Disclosure of Invention

Problems to be solved by the invention

An object of the present disclosure is to provide a technique that can achieve a balance between user convenience and vehicle safety in a vehicle in which an internal combustion engine is operated by remote operation and pre-air conditioning is performed in the vehicle.

Means for solving the problems

The present disclosure can be understood as a control device applied to a vehicle that starts an internal combustion engine and pre-air-conditions the vehicle interior in accordance with a remote signal transmitted from a remote controller. In this case, the control device may include a control unit that sets a control mode of the vehicle to a driving prohibition mode that is a control mode in which a driving operation for the vehicle is invalidated when the pre-air conditioning in the vehicle is started based on the remote signal, and releases the driving prohibition mode while continuing the operation of the internal combustion engine when a predetermined release operation is detected while the remote controller is present in the vehicle when the control mode of the vehicle is set to the driving prohibition mode.

Detailed Description

In the present embodiment, an example in which the vehicle control device according to the present disclosure is applied to a vehicle control system is described. The control system of the vehicle in this example is a system that performs pre-air conditioning in the vehicle by remote operation using exhaust heat during operation of the internal combustion engine, a compressor driven by the internal combustion engine, or the like. The "pre-air conditioning" referred to herein is to heat or cool the interior of the vehicle in advance before the vehicle starts to run (for example, before a user gets into the vehicle or before the user starts a driving operation of the vehicle). The vehicle to which such a control system is applied may be a vehicle equipped with an internal combustion engine as a prime mover, or may be a vehicle equipped with a hybrid system equipped with an internal combustion engine and an electric motor as a prime mover.

In the control system of the vehicle in the present example, the remote controller used by the user receives a pre-air-conditioning request from the user. When the remote controller receives the pre-air-conditioning request, the remote controller transmits a remote signal to a control device of the vehicle. The remote signal is a signal including a request for causing the pre-air conditioning in the vehicle to be performed. The remote signal may include a target temperature in the vehicle and/or information on a scheduled travel start time.

When the control device of the vehicle receives the remote signal, the control unit starts the internal combustion engine and starts pre-air conditioning. This enables the interior of the vehicle to be set to an appropriate temperature in advance before the user gets on the vehicle or before the user starts the driving operation of the vehicle.

Here, a mode may be considered in which, when a riding action to the vehicle (for example, unlocking of a door, opening of a door, or the like) is detected after the pre-air conditioning is started, the operation of the internal combustion engine is automatically stopped. According to such a method, it is possible to prevent a situation in which the vehicle is improperly driven by a third party other than the user of the vehicle. However, even when the user of the vehicle performs the riding operation after the start of the pre-air conditioning, the operation of the internal combustion engine is automatically stopped. Therefore, in order for a user of the vehicle to run the vehicle after starting the pre-air conditioning, the user needs to perform a restart operation of the internal combustion engine. This may reduce the convenience of the user of the vehicle. On the other hand, if the operation of the internal combustion engine is continued even after the detection of the riding action, there is a possibility that the vehicle is improperly driven by a third party. This may reduce the safety of the vehicle.

Therefore, in the present disclosure, the control portion sets the control mode of the vehicle to the driving prohibition mode at the time of starting the pre-air conditioning. The driving prohibition mode is a control mode that invalidates the driving operation for the vehicle. The driving operation that is made invalid in such a driving prohibition mode includes a driving operation for starting the running of the vehicle. Examples of such a driving operation include a steering wheel operation, a shift operation, and an accelerator operation. The driving operation to be invalidated in the driving prohibition mode is not limited to the above, and may include, for example, a release operation of the parking brake. When the control mode of the vehicle is set to the driving prohibition mode at the time of starting the pre-air conditioning, it is possible to suppress a situation in which the third party improperly drives the vehicle during execution of the pre-air conditioning. This ensures the safety of the vehicle.

Further, when a predetermined cancel operation is detected while the remote controller is present in the vehicle when the control mode of the vehicle is set to the drive prohibition mode (pre-air-conditioning is being performed), the control portion cancels the drive prohibition mode while continuing to operate the internal combustion engine. That is, when the conditions that the remote controller is present in the vehicle interior and the predetermined release operation is detected are satisfied, the driving prohibition mode is released while the internal combustion engine continues to operate. The predetermined cancellation operation is, for example, an operation different from the operation performed when the vehicle starts traveling, and is preferably an operation in which two or more operations are combined. For example, the predetermined releasing operation may be a braking operation, or may be an operation combining a braking operation and an operation of a button for starting the internal combustion engine or the like. Thus, if the user of the vehicle holds the remote controller and rides on the vehicle and performs a predetermined cancel operation, the drive prohibition mode is cancelled while the internal combustion engine continues to operate. As a result, when the user of the vehicle drives the vehicle after the start of the pre-air conditioning, the user becomes unnecessary to perform the restart operation of the internal combustion engine.

Here, the two conditions are set as the conditions for canceling the driving prohibition mode while continuing the operation of the internal combustion engine in order to prevent the vehicle from being accidentally driven by an erroneous operation by a family member of the user or the like in addition to preventing the vehicle from being abnormally driven by a third party. For example, when the internal combustion engine is continuously operated and the driving prohibition mode is canceled only on condition that the predetermined cancel operation is detected, if a third party who may know the predetermined cancel operation does not hold the remote controller and rides on the vehicle, the improper driving of the vehicle by the third party may be permitted. Further, when the internal combustion engine is continuously operated and the driving prohibition mode is canceled on the condition that only the remote controller is present in the vehicle, there is a possibility that accidental travel of the vehicle due to an erroneous operation by a family member or the like of the user is permitted when the family member or the like holds the remote controller and rides the vehicle. Therefore, if the internal combustion engine is continuously operated and the driving prohibition mode is canceled when the above two conditions are satisfied, it is possible to suppress the occurrence of the above-described problem and to suppress a reduction in the convenience of the user of the vehicle.

In addition, the predetermined cancellation operation may be set to an operation that is difficult for the third party to know, from the viewpoint of further improving the safety of the vehicle. For example, the combination of two or more operations arbitrarily set by the user may be used, or an operation of inputting a password arbitrarily set by the user to the in-vehicle terminal may be used.

According to the control device for the vehicle, the balance between the convenience of the user and the safety of the vehicle can be realized.

Further, when an operation (prohibition operation) different from a predetermined cancel operation is detected when the control mode of the vehicle is set to the drive prohibition mode (when pre-air conditioning is being performed), the control unit may automatically stop the operation of the internal combustion engine. The "prohibition operation" referred to herein includes, for example, operations for starting the running of the vehicle such as a steering wheel operation, a shift operation, and an accelerator operation. If the operation of the internal combustion engine is automatically stopped when such an operation prohibition is detected, it is possible to more reliably suppress the start of the travel of the vehicle against the intention of the user due to an improper operation by a third party, an erroneous operation by the family of the user, or the like.

Further, when the control mode of the vehicle is set to the driving prohibition mode (when the pre-air conditioner is being executed), the control unit may automatically stop the operation of the internal combustion engine when a predetermined cancel operation is detected while the remote controller is not present in the vehicle. This makes it possible to more reliably suppress a situation in which a third party who is likely to be notified of a predetermined cancel operation improperly drives the vehicle.

When the operation of the internal combustion engine is automatically stopped for the various reasons described above, the control unit may transmit a signal for notifying the user that the operation of the internal combustion engine has been automatically stopped to the remote controller. Thus, the user of the vehicle can recognize that there is a possibility that the third party performs an improper operation on the vehicle, or that the family of the user or the like performs an improper operation on the vehicle. As a result, the user can also confirm the state of the vehicle.

Further, when the operation of the internal combustion engine is automatically stopped, the control unit may set the control mode of the vehicle to a safe mode, which is a control mode for invalidating the restart operation of the internal combustion engine. This can suppress the third party from improperly restarting the internal combustion engine.

Here, it is desirable to have a mode in which the user can release the security mode when it is confirmed that the reason why the operation of the internal combustion engine is automatically stopped is an erroneous operation by the family of the user or the like, that is, when it is confirmed that an unauthorized operation by a third party is not performed. Therefore, when the control mode of the vehicle is set to the safe mode, the control unit may release the safe mode when a predetermined release operation is detected in a state where the remote controller is present in the vehicle. That is, the security mode may be released if a user of the vehicle rides in the vehicle while holding the remote controller and performs a predetermined release operation. The predetermined cancellation operation at this time may be the same operation as the predetermined cancellation operation for canceling the driving prohibition mode, or may be a different operation. Thus, the safety of the vehicle can be improved while ensuring the convenience of the user.

The above-described drive prohibition modes may include a first drive prohibition mode in which the operation of opening the door of the vehicle and the driving operation with respect to the vehicle are prohibited from being executed, and a second drive prohibition mode in which the operation of opening the door of the vehicle is permitted and the driving operation with respect to the vehicle is prohibited from being executed. Further, the control unit may set the control mode of the vehicle to the first driving prohibition mode after the start of the pre-air conditioning and until the detection of the normal door unlocking operation. The "normal door unlocking operation" referred to herein is, for example, an unlocking operation using a remote controller corresponding to the vehicle, an unlocking operation using a physical key corresponding to the vehicle, or the like. This can suppress the driving operation of the vehicle from being performed by the third party unfairly, and also can suppress the third party from riding in the vehicle unfairly. In addition, the prohibition operation during the first driving prohibition mode setting may include an operation for starting the travel of the vehicle such as a steering wheel operation, a shift operation, and an accelerator operation, as well as an operation for opening a door of the vehicle. Thus, the operation of the internal combustion engine can be automatically stopped when an unauthorized door opening operation by a third party is detected, in addition to the case where an unauthorized driving operation by a third party is detected.

Further, the control unit may set the control mode of the vehicle to the second driving prohibition mode after the detection of the normal door unlocking operation. That is, the control unit may switch the control mode of the vehicle from the first drive prohibition mode to the second drive prohibition mode when a normal door unlock operation is detected. Thus, after the normal door unlocking operation is performed, the user of the vehicle can open the door and get on the vehicle, or the user of the vehicle can open the door and load the cargo. Further, it is possible to suppress a situation in which the vehicle travels due to an improper driving operation performed by a third party after a normal door unlocking operation is performed, and a situation in which the vehicle travels unexpectedly due to an erroneous operation of a family member of the user or the like. In addition, the prohibition operations during the setting of the second driving prohibition mode may include operations for starting the travel of the vehicle such as a steering wheel operation, a shift operation, and an accelerator operation, and may not include an operation for opening a door of the vehicle. This can prevent the operation of the internal combustion engine from being automatically stopped when the user, family member, or the like of the vehicle performs a door opening operation. Further, the operation of the internal combustion engine can be automatically stopped when the third party performs an improper driving operation or when a driving operation is performed by mistake, such as by the family of the user of the vehicle.

< embodiment >

A more specific embodiment of the vehicle control system described above will be described with reference to the drawings.

(System outline)

Fig. 1 is a diagram showing a schematic configuration of a vehicle control system according to the present embodiment. As shown in fig. 1, the control system in this example is configured to include a vehicle 1 and a remote controller 200. The vehicle 1 in this example is a vehicle driven by an internal combustion engine 10 as a prime mover, and is equipped with an air conditioner 15 for air conditioning (air conditioning) the vehicle interior. The remote controller 200 is a device for remotely operating locking and unlocking of the vehicle 1, an air conditioner in the vehicle, and the like, and is used by a user of the vehicle 1. In such a control system, the user can perform air conditioning (pre-air conditioning) in the vehicle by the air conditioner 15 by operating the remote controller 200 before riding in the vehicle 1. This enables the user to set the interior at a comfortable temperature in advance before riding in the vehicle 1.

(Structure of vehicle 1)

Here, a specific configuration of the vehicle 1 in the present embodiment will be described. As shown in fig. 1, a vehicle 1 is a vehicle equipped with an internal combustion engine 10 as a prime mover. The internal combustion engine 10 is a spark ignition type internal combustion engine (gasoline engine) or a compression ignition type internal combustion engine (diesel engine) having at least one cylinder. The internal combustion engine 10 rotationally drives the drive wheels 54 via the transmission 12 and the like. The vehicle 1 may be a vehicle equipped with a hybrid system including an internal combustion engine and an electric motor as a prime mover.

The vehicle 1 further includes a steering actuator 11, a transmission 12, a brake actuator 13, a door lock actuator 14, an air conditioner 15, and the like. The steering actuator 11 is an actuator for changing the steering angle of the steered wheels. The transmission 12 increases or decreases the rotational speed of an output shaft (crankshaft) of the internal combustion engine 10, or reverses the rotational direction of the output shaft of the transmission 12 with respect to the rotational direction of the crankshaft. The brake actuator 13 is an actuator for changing the braking force acting on the vehicle 1. The door lock actuator 14 is an actuator for locking and unlocking the doors (a car door that is opened and closed when a car as a riding space is loaded and unloaded, a trunk door that is opened and closed when cargo is loaded and unloaded to and from the trunk, and the like) of the vehicle 1. The air conditioner 15 in this example is a device that heats the vehicle interior by using the heat (exhaust heat) released from the internal combustion engine 10 when the internal combustion engine 10 is operating.

As shown in fig. 2, the air conditioner 15 includes, for example, a heat exchanger 15A and an opening/closing valve 15B. The heat exchanger 15A exchanges heat between the cooling water circulating in the internal combustion engine 10 and the air for heating. The heat exchanger 15A moves heat from the cooling water, which has absorbed heat released from the internal combustion engine 10, to the heating air. The opening/closing valve 15B blocks or opens the flow of the cooling water from the internal combustion engine 10 to the heat exchanger 15A. The on-off valve 15B is opened when heating by the air conditioner 15 is required, and is closed when heating by the air conditioner 15 is not required.

The air conditioner 15 may be configured to have a function of cooling the vehicle interior. In this case, the air conditioner 15 may be configured to further include a compressor for compressing the refrigerant by the output of the internal combustion engine 10, a condenser for cooling the refrigerant compressed by the compressor, a receiver-drier for temporarily storing the refrigerant cooled by the condenser, an expansion valve for atomizing the refrigerant, an evaporator for performing heat exchange between the cooling air and the refrigerant, and the like.

The vehicle 1 configured as described above is mounted with an ECU (Electronic Control Unit) 30 for controlling devices mounted on the vehicle 1. ECU30 controls devices mounted on vehicle 1 based on a driving operation by a user, detection signals from various sensors mounted on vehicle 1, and a remote signal from remote controller 200. Here, the sensors and the like connected to the ECU30 include the brake sensor 20, the acceleration sensor 21, the steering sensor 22, the shift sensor 23, the start button 24, the door handle sensor 25, and the like. The brake sensor 20 detects an operation amount (depression amount) of the brake pedal. The acceleration sensor 21 detects an operation amount (depression amount) of an accelerator pedal. The steering sensor 22 detects an operation amount (steering angle) of a steering wheel and/or a steering torque. The shift sensor 23 detects the position of the shift lever. The start button 24 is a button operated by a user when turning on or off the auxiliary power supply of the vehicle 1 and when starting or stopping the internal combustion engine 10. The door handle sensor 25 detects an operation of a door handle (door handle) provided on an outer side of a door of the vehicle 1.

The ECU30 controls the brake actuator 13 based on a detection signal of the brake sensor 20. The ECU30 controls the intake air amount and/or the fuel injection amount of the internal combustion engine 10 based on the detection signal of the acceleration sensor 21. The ECU30 controls the steering actuator 11 based on a detection signal from the steering sensor 22. The ECU30 controls the transmission 12 based on a detection signal from the shift sensor 23. Further, the ECU30 controls the door lock actuator 14 based on a remote signal including a lock request or an unlock request from the remote controller 200. The ECU30 controls the air conditioning device 15 based on an operation of an air conditioning operation panel or the like provided in the vehicle, a remote signal including a pre-air conditioning request from the remote controller 200, or the like.

The ECU30 may be constituted by one ECU, or may be constituted to include a plurality of ECUs. For example, the ECU30 may be configured to include an ECU that controls the internal combustion engine 10, an ECU that controls the steering actuator 11, an ECU that controls the transmission 12, an ECU that controls the brake actuator 13, an ECU that controls the door lock actuator 14, an ECU that controls the air-conditioning apparatus 15, and an ECU that processes signals transmitted and received between the remote controller 200 and the vehicle 1. In this case, the plurality of ECUs may be connected to each other via an in-vehicle Network such as CAN (Controller Area Network).

(hardware construction of ECU and remote controller)

The main storage unit 302 and the auxiliary storage unit 303 are computer-readable recording media. The hardware configuration of the ECU30 is not limited to the example shown in fig. 3, and components may be omitted, replaced, or added as appropriate. The ECU30 loads and executes a program stored in a recording medium into the work area of the main storage unit 302 via the processor 301, and controls each functional configuration unit and the like by executing the program, thereby realizing a function in accordance with a predetermined purpose.

The Processor 301 is, for example, a CPU (Central Processing Unit) or a DSP (Digital Signal Processor). The processor 301 controls the ECU30 and performs various information processing operations. The main storage unit 302 includes, for example, a RAM (Random Access Memory) and a ROM (Read Only Memory). The auxiliary storage unit 303 is, for example, an EPROM (Erasable Programmable ROM) or a Hard Disk Drive (Hard Disk Drive). Further, the auxiliary storage portion 303 can include a removable medium, i.e., a portable recording medium. Examples of the removable medium include a USB (Universal Serial Bus) memory, a CD (Compact Disc), and a DVD (Digital Versatile Disc).

The auxiliary storage unit 303 stores various programs, various data, and various tables in a readable and writable manner in a recording medium. The program stored in the auxiliary storage unit 303 includes an Operating System (OS). In addition, a part or all of the information may be stored in the main storage unit 302. In addition, a part or all of the information stored in the main storage unit 302 may be stored in the auxiliary storage unit 303.

Communication unit 304 transmits and receives information between an external device and ECU 30. The communication unit 304 is, for example, a wireless communication circuit for wireless communication. The wireless communication circuit performs data communication with the remote controller 200, for example, according to the Bluetooth (registered trademark) LowEnergy standard (hereinafter, referred to as BLE). The wireless Communication circuit may be configured to perform wireless Communication with the remote controller 200 by NFC (Near Field Communication), UWB (Ultra-Wideband), Wi-Fi (registered trademark), or the like. The wireless communication circuit may be configured to connect to the network using a mobile communication service such as 5G (5th Generation) or LTE (Long Term Evolution). In this case, the Network is, for example, a WAN (Wide Area Network) which is a world-scale public communication Network such as the internet, or a telephone communication Network such as a mobile phone. The communication unit 304 may include a circuit for receiving Radio waves in a high Frequency (RF) band from the remote controller 200. The communication unit 304 may include a circuit that transmits radio waves in a Low Frequency (LF) band for searching for a remote controller present in the vehicle interior space.

The series of processes executed by the ECU30 configured as described above can be executed by hardware or software.

Next, the remote controller 200 is a small computer for remotely controlling the locking and unlocking of the doors of the vehicle 1, the air conditioner 15, and the like as described above. Such a computer is a small computer that can be carried by a user, such as an electronic key (portable device) of a smart key, a smartphone, a mobile phone, a tablet terminal, a personal information terminal, and a wearable computer (smart watch or the like). The remote controller 200 may be a Personal Computer (PC) connected to the ECU30 via a network such as the internet as a public communication network.

The remote controller 200 has: a processor 201, a main storage unit 202, an auxiliary storage unit 203, a display unit 204, an input unit 205, and a communication unit 206. The processor 201, the main storage 202, and the auxiliary storage 203 are the same as the processor 301, the main storage 302, and the auxiliary storage 303 of the ECU30, and therefore, description thereof is omitted. The Display unit 204 is, for example, an LCD (Liquid Crystal Display) or EL (Electroluminescence) panel. The input unit 205 includes, for example, a touch panel or a push button capable of inputting symbols such as characters, a microphone capable of inputting voice, a camera capable of capturing a moving image or a still image, and the like. The communication unit 206 is a communication circuit that accesses a network using a mobile communication service, for example, and performs data communication with the ECU 30. Communication unit 206 may be configured to communicate with ECU30 by the same short-range communication standard as that of communication unit 304 of ECU 30. The communication unit 206 may include a circuit for transmitting radio waves in the RF band to the ECU30 of the vehicle 1 and a circuit for receiving polling radio waves in the LF band.

The series of processes executed by the remote controller 200 configured as described above can be executed by hardware or software.

(functional Structure of ECU)

Next, a functional structure of the ECU30 will be described with reference to fig. 4. As shown in fig. 4, the ECU30 in this example includes, as its functional components, a remote signal processing unit F310, a lock/unlock processing unit F320, a pre-air conditioning processing unit F330, and a mode processing unit F340. The remote signal processing unit F310, the lock/unlock processing unit F320, the pre-air conditioning processing unit F330, and the mode processing unit F340 are formed by the processor 301 of the ECU30 executing computer programs on the main storage unit 302. Any one or a part of the remote signal processing unit F310, the lock/unlock processing unit F320, the pre-air conditioning processing unit F330, and the mode processing unit F340 may be formed by a hardware circuit.

When the communication unit 304 receives the remote signal transmitted from the remote controller 200, the remote signal processing unit F310 executes the authentication process of the remote controller 200. In the authentication process, for example, the identity of the authentication information stored in the main storage unit 302 or the auxiliary storage unit 303 and the authentication information included in the remote signal is verified. When the two pieces of authentication information match, it is determined that the authentication is successful. On the other hand, if the two pieces of authentication information do not match, it is determined that the authentication has failed. The authentication process is not limited to the example of the implementation by the above-described method, and may be implemented by a method using asymmetric encryption.

If the authentication process is successful, if the remote signal is a signal including an unlock request or a lock request (hereinafter, also referred to as an "unlock request signal" or a "lock request signal"), the unlock request or the lock request is transmitted from the remote signal processing unit F310 to the lock/unlock processing unit F320. When the ECU30 receives the unlock request signal, if pre-air conditioning is performed, the authentication result of the authentication process is notified from the remote signal processing unit F310 to the mode processing unit F340. In the case where the authentication is determined to be successful in the authentication process, if the remote signal is a signal including a pre-air-conditioning request (hereinafter, also referred to as "pre-air-conditioning request signal"), the pre-air-conditioning request is transmitted from the remote signal processing unit F310 to the pre-air-conditioning processing unit F330.

The locking/unlocking processing unit F320 controls the door lock actuator 14 in response to the unlocking request or the locking request transmitted from the remote signal processing unit F310. For example, if the request transmitted from the remote signal processing unit F310 to the locking/unlocking processing unit F320 is an unlocking request, the locking/unlocking processing unit F320 transmits an unlocking command to the door lock actuator 14. Further, if the request transmitted from the remote signal processing unit F310 to the locking/unlocking processing unit F320 is a locking request, the locking/unlocking processing unit F320 transmits a locking command to the door lock actuator 14. The unlock command and the lock command are transmitted from the ECU30 to the door lock actuator 14 via an in-vehicle network such as CAN.

The pre-air conditioning processing unit F330 controls the internal combustion engine 10 and the air conditioner 15 in accordance with the pre-air conditioning request transmitted from the remote signal processing unit F310. For example, the pre-air conditioning processing unit F330 first executes a start-up process of the internal combustion engine 10. In the start-up process, for example, a process of operating a starter motor, a process of operating a fuel injection valve, a process of operating an ignition plug, and the like are executed. When the start of the internal combustion engine 10 is completed, the pre-air conditioning processing portion F330 operates the air conditioning device 15 and starts pre-air conditioning. Specifically, the pre-air conditioning unit F330 opens the opening/closing valve 15B. Thus, in the heat exchanger 15A, heat is exchanged between the cooling water that has absorbed the heat released from the internal combustion engine 10 and the air for heating, whereby the air for heating is heated. As a result, the interior of the vehicle can be set at an appropriate temperature before the user gets into the vehicle 1. When the pre-air conditioning process unit F330 starts the pre-air conditioning, a pre-air conditioning start notification is notified from the pre-air conditioning process unit F330 to the mode process unit F340. Various commands transmitted from the pre-air conditioning unit F330 to the internal combustion engine 10 and the air conditioner 15 are transmitted via an in-vehicle network such as CAN.

Here, in the case where the information specifying the scheduled travel start time of the vehicle 1 is included in the pre-air-conditioning request, the pre-air-conditioning processing unit F330 may start the internal combustion engine 10 and start the pre-air-conditioning by the air-conditioning device 15 before a predetermined time of the scheduled travel start time. The "predetermined time" referred to herein may be a fixed value or a variable value that is changed in accordance with an external temperature, a target temperature in the vehicle, or the like.

The mode processing unit F340 sets and changes the control mode of the vehicle 1. For example, upon receiving the pre-air-conditioning start notification from the pre-air-conditioning processing unit F330, the mode processing unit F340 sets the control mode of the vehicle 1 to the driving prohibition mode. The driving prohibition mode is a mode in which a predetermined operation for the vehicle 1 is invalidated. The drive prohibition modes in this example include a first drive prohibition mode and a second drive prohibition mode. The first driving prohibition mode is a mode in which an operation of opening the doors of the vehicle 1 and a driving operation (a steering wheel operation, a shift operation, an accelerator operation, and the like) with respect to the vehicle 1 are invalidated. The second driving prohibition mode is a mode in which the driving operation (steering wheel operation, shift operation, accelerator operation, and the like) with respect to the vehicle 1 is invalidated while the operation of opening the doors of the vehicle 1 is permitted.

Here, the first driving prohibition mode is set when the pre-air conditioning is started by the pre-air conditioning processing unit F330 (when the mode processing unit F340 receives the pre-air conditioning start notification). During the setting in the first driving prohibition mode, the opening operation of the door and the driving operation performed by the third party not holding the remote controller 200 corresponding to the vehicle 1 are set to be invalid. Thus, even if the user of the vehicle 1 leaves the vehicle 1 while the pre-air conditioning is being performed, it is possible to suppress an improper ride and an improper driving operation by a third party.

Further, when the prohibition operation is detected while the first driving prohibition mode is being set, the mode processing portion F340 may automatically stop the operation of the internal combustion engine 10. The prohibition operations in this case include door opening operations of the doors (operations of the door handles) and operations for starting travel of the vehicle 1 (steering wheel operations, shift operations, accelerator operations, and the like). Further, the mode processing unit F340 may switch the control mode of the vehicle 1 from the first driving prohibition mode to the safe mode. The safe mode is a mode in which a restart operation of the internal combustion engine 10 (for example, an operation of the start button 24) is disabled. Thus, even if a third party can improperly open the doors of the vehicle 1, the third party cannot restart the internal combustion engine 10. As a result, it is possible to more reliably suppress the vehicle 1 from being improperly driven.

Further, when a normal unlocking operation is detected while the vehicle is in the setting of the first drive prohibition mode, the mode processing portion F340 switches the control mode of the vehicle 1 from the first drive prohibition mode to the second drive prohibition mode. The "normal unlocking operation" referred to herein is an unlocking operation performed by the remote controller 200 corresponding to the vehicle 1, an unlocking operation performed by a physical key corresponding to the vehicle 1, or the like. In the case where the user of the vehicle 1 performs an unlocking operation by the remote controller 200, an unlocking request signal is sent from the remote controller 200 to the ECU 30. In this case, as described above, the authentication process performed by the remote signal processing section F310 is executed. When the authentication process is judged to be successful, the door is unlocked by the lock/unlock processing unit F320 sending an unlock command to the door lock actuator 14. Further, as described above, the authentication result of the authentication process is transferred from the remote signal processing unit F310 to the pattern processing unit F340. If the authentication result is that the authentication is successful, the mode processing portion F340 switches the control mode of the vehicle 1 from the first drive prohibition mode to the second drive prohibition mode. On the other hand, if the authentication result is that the authentication has failed, the lock/unlock processing unit F320 does not unlock the vehicle door, and the mode processing unit F340 continues to set the first driving prohibition mode.

When switching from the first drive prohibition mode to the second drive prohibition mode is performed, the user of the vehicle 1 is permitted to open the vehicle door. Thereby, the user of the vehicle 1 can ride on the vehicle 1 or load the cargo into the vehicle 1. However, since the driving operation with respect to the vehicle 1 is invalidated, even if the user leaves the vehicle 1 with the doors unlocked, it is possible to suppress the vehicle 1 from traveling due to an improper driving operation by a third party, an erroneous operation by the family of the user, or the like.

Further, when the prohibition operation is detected while the second driving prohibition mode is being set, the mode processing portion F340 may automatically stop the operation of the internal combustion engine 10. In the prohibition operation in this case, the operation for starting the travel of the vehicle 1 is included, but the door opening operation of the door is not included. Further, the mode processing unit F340 may switch the control mode of the vehicle 1 from the second driving prohibition mode to the safe mode. This can suppress unnecessary stop of the operation of the internal combustion engine 10 due to the door opening by the user of the vehicle 1. Further, when the prohibition operation is improperly performed by a third party or when the prohibition operation is erroneously performed by a family member of the user or the like, the operation of the internal combustion engine 10 can be automatically stopped. Further, when the prohibition operation is improperly performed by the third party, the third party may be inhibited from restarting the internal combustion engine 10. As a result, after the door of the vehicle 1 is unlocked by the normal unlocking operation, it is possible to more reliably suppress a case where the third party improperly travels the vehicle 1, a case where the family of the user or the like erroneously travels the vehicle 1, and the like.

Here, when the operation of the internal combustion engine 10 is automatically stopped during the setting of the first drive prohibition mode or during the setting of the second drive prohibition mode, the mode processing unit F340 may transmit a signal (hereinafter, also referred to as "stop notification signal") for notifying the user of the vehicle 1 of the stop to the remote controller 200. Thus, the user of the vehicle 1 can recognize that an improper operation or an erroneous operation is performed on the vehicle 1 during execution of the pre-air conditioning. As a result, the user of the vehicle 1 can also confirm the state of the vehicle 1.

Further, when a predetermined cancel operation is performed in a state where the remote controller 200 corresponding to the vehicle 1 is present in the vehicle while the second driving prohibition mode is set, the mode processing portion F340 cancels the second driving prohibition mode while continuing the operation of the internal combustion engine 10. After the second driving prohibition mode is released, the driving operation for the vehicle 1 is permitted as long as the remote controller 200 is present in the vehicle. Thus, the user of the vehicle 1 can start the running of the vehicle 1 without having to take time and effort to restart the internal combustion engine 10.

The predetermined release operation is, for example, an operation of operating the start button 24 simultaneously with the operation of the brake pedal. Such a predetermined release operation is detected based on the detection signals of the brake sensor 20 and the start button 24. That is, when the operation of the start button 24 is detected simultaneously with the detection of the operation of the brake pedal by the brake sensor 20, it can be determined that the predetermined release operation is performed.

Further, the determination as to whether or not the remote controller 200 corresponding to the vehicle 1 is present in the vehicle is performed in the following order. That is, the mode processing unit F340 first performs polling based on radio waves in the LF band or the like to acquire authentication information of the remote controller present in the vehicle. At this time, if no remote controller exists in the vehicle, the authentication information cannot be acquired. Therefore, the mode processing portion F340 determines that the remote controller 200 corresponding to the vehicle 1 is not present in the vehicle. Further, if any remote controller exists in the vehicle, the mode processing portion F340 performs authentication processing on the authentication information acquired by the polling. The authentication process at this time is performed in the same order as the authentication process performed by the remote signal processing unit F310. When it is determined that the authentication has failed in the authentication process, the mode processing portion F340 determines that the remote controller 200 corresponding to the vehicle 1 is not present in the vehicle. On the other hand, when it is determined that the authentication is successful in the authentication process, the mode processing portion F340 determines that the remote controller 200 corresponding to the vehicle 1 exists in the vehicle.

Here, when it is determined that the remote controller 200 corresponding to the vehicle 1 is not present in the vehicle when the predetermined release operation is detected, the mode processing unit F340 may automatically stop the operation of the internal combustion engine 10. Then, the mode processing unit F340 may switch the control mode of the vehicle 1 from the second driving prohibition mode to the safe mode. Thus, it is possible to suppress the vehicle 1 from being run improperly or the vehicle 1 from being run unintentionally, for example, when a third party performs a predetermined cancel operation improperly, or when a family member of a user performs an operation similar to the predetermined cancel operation accidentally.

The predetermined cancellation operation is not limited to the above example, and may be changed according to regulations and the like. The predetermined cancel operation may be a combination of two or more operations arbitrarily set by the user, or may be an operation of inputting a password arbitrarily set by the user into the input device mounted on the vehicle.

In addition, even when the control mode of the vehicle 1 is set to the safe mode, the safe mode may be released on condition that the predetermined release operation is performed in a state where the remote controller 200 is present in the vehicle. Thus, for example, when the operation of the internal combustion engine 10 is automatically stopped due to an erroneous operation by a family member of the user or the like, the user can cancel the safe mode.

The same driving prohibition mode may be set during a period from the start of pre-air conditioning until the execution of the normal unlocking operation by the remote controller 200 and during a period after the execution of the normal unlocking operation by the remote controller 200. That is, the drive prohibition mode corresponding to the second drive prohibition mode may be set in these periods. In this case, it is possible to suppress at least the vehicle 1 from traveling due to an improper driving operation.

(functional Structure of remote controller)

Next, a functional configuration of the remote controller 200 will be described with reference to fig. 5. As shown in fig. 5, the remote controller 200 in this example includes, as its functional structural elements, a request processing section F210 and a communication processing section F220. These request processing unit F210 and communication processing unit F220 are formed by the processor 201 of the remote controller 200 executing a computer program on the main storage unit 202. Further, either one of the request processing unit F210 and the communication processing unit F220 or a part thereof may be formed by a hardware circuit.

When the pre-air-conditioning request operation is performed on the remote controller 200, the request processing part F210 generates a remote signal (pre-air-conditioning request signal) including the authentication information of the remote controller 200 and the pre-air-conditioning request. When the unlock request operation or the lock request operation is performed on the remote controller 200, the request processing unit F210 generates a remote signal (an unlock request signal or a lock request signal) including the authentication information of the remote controller 200 and the unlock request or the lock request. The remote signal generated by the request processing section F210 is transmitted to the communication processing section F220.

The communication processing unit F220 transmits and receives various signals to and from the ECU30 of the vehicle 1. For example, when receiving the remote signal generated by the request processing unit F210, the remote signal is transmitted to the ECU30 through the communication unit 206. When the communication unit 206 receives the stop notification signal from the ECU30, the communication processing unit F220 also has a function of displaying, on the display unit 204, character information or the like indicating that the internal combustion engine 10 has been automatically stopped during execution of the pre-air conditioning. When the communication unit 206 receives the polling radio wave from the ECU30 at the time of the search of the remote controller 200, the communication processing unit F220 also has a function of transmitting the authentication information of the remote controller 200 to the ECU30 via the communication unit 206.

(flow of treatment)

Next, a flow of processing executed by the ECU30 in the present embodiment will be described with reference to fig. 6. Fig. 6 is a flowchart showing the flow of processing executed by the ECU30 triggered by the start of the pre-air conditioning processing.

As described above, when the pre-air conditioning performed by the pre-air conditioning processing unit F330 is started, the pre-air conditioning start notification is transmitted from the pre-air conditioning processing unit F330 to the mode processing unit F340. The mode processing unit F340 sets the control mode of the vehicle 1 to the first driving prohibition mode, triggered by the reception of the pre-air-conditioning start notification (step S101).

While the first driving prohibition mode is set, the mode processing unit F340 determines whether or not the prohibition operation is detected by monitoring the detection signal of the door handle sensor 25 in addition to the steering sensor 22, the shift sensor 23, and the acceleration sensor 21 (step S102). The prohibition operation during the first driving prohibition mode setting includes an operation to open the door (operation of the door handle) in addition to the driving operations such as the steering wheel operation, the shift operation, and the accelerator operation.

If any one of the steering wheel operation, the shift operation, the accelerator operation, and the door handle operation is not detected while in the first drive prohibition mode setting (negative determination in step S102), the ECU30 makes a determination as to whether or not an unlock request signal is received (step S103).

If the ECU30 does not receive the unlocking request signal (negative determination in step S103), the processes after step S102 are executed again. On the other hand, if the ECU30 receives the unlock request signal (affirmative determination in step S103), the remote signal processing section F310 executes authentication processing of the authentication information included in the unlock request signal (step S104). The result of the authentication process performed by the remote signal processing unit F310 is transmitted from the remote signal processing unit F310 to the pattern processing unit F340.

The mode processing unit F340 determines whether or not the result of the authentication process performed by the remote signal processing unit F310 is an authentication success (step S105). If the result of the authentication process performed by the remote signal processing portion F310 is that the authentication has failed (negative determination in step S105), the ECU30 receives an unlocking request signal from a remote controller different from the remote controller 200 corresponding to the vehicle 1. In this case, the processing after step S102 is executed again. On the other hand, if the authentication is successful as a result of the authentication process performed by the remote signal processing unit F310 (affirmative determination in step S105), the mode processing unit F340 switches the control mode of the vehicle 1 from the first drive prohibition mode to the second drive prohibition mode (step S106).

While the second driving prohibition mode is set, the mode processing portion F340 monitors the detection signals of the steering sensor 22, the shift sensor 23, and the acceleration sensor 21 to determine whether or not the prohibition operation is detected (step S107). The prohibition operations during the setting of the second driving prohibition mode include driving operations such as a steering wheel operation, a shift operation, and an accelerator operation, but do not include a door opening operation of the door (operation of the door handle).

If any of the steering wheel operation, the shift operation, and the accelerator operation is not detected while in the second driving prohibition mode setting (negative determination in step S107), a determination is made as to whether a predetermined release operation is detected (step S108). The predetermined release operation is, for example, an operation of the start button 24 while the brake operation is performed. Therefore, the mode processing unit F340 monitors the detection signal of the brake sensor 20 and the detection signal of the start button 24 to determine whether or not a predetermined release operation is detected.

If the operation of the start button 24 is not detected while the operation of the brake pedal is detected by the brake sensor 20, a predetermined release operation is not performed (negative determination in step S108). In this case, the processing after step S107 is executed again. On the other hand, if the operation of the start button 24 is detected simultaneously with the detection of the operation of the brake pedal by the brake sensor 20, a predetermined release operation is performed (affirmative determination in step S108). In this case, the mode processing portion F340 determines whether or not the remote controller 200 corresponding to the vehicle 1 is present in the vehicle interior (step S109). For example, the mode processing unit F340 searches for a remote controller by polling radio waves and the like using the LF band. Thus, when the authentication information of the remote controller is acquired, the mode processing section F340 executes the authentication process. When it is determined in the authentication process that the authentication is successful, it is determined that the remote controller 200 corresponding to the vehicle 1 is present in the vehicle (affirmative determination in step S109). In this case, the mode processing portion F340 cancels the setting of the second driving prohibition mode (step S110).

Further, the mode processing portion F340 automatically stops the operation of the internal combustion engine 10 (step S111) when the prohibition operation is detected while the first drive prohibition mode setting is in progress (affirmative determination in step S102), when the prohibition operation is detected while the second drive prohibition mode setting is in progress (affirmative determination in step S107), and when the remote controller 200 is not present in the vehicle when a predetermined release operation is detected (negative determination in step S109).

When the operation of the internal combustion engine 10 is automatically stopped, the mode processing portion F340 transmits a stop notification signal to the remote controller 200 via the communication portion 304 (step S112). Next, the mode processing portion F340 switches the control mode of the vehicle 1 from the first driving prohibition mode or the second driving prohibition mode to the safe mode (step S113). Further, while the safe mode is being set, the safe mode may be released when the predetermined release operation is detected while the remote controller 200 corresponding to the vehicle 1 is present in the vehicle.

In addition, it is assumed that the pre-air-conditioning request operation may be performed by the remote controller 200 after the user gets into the vehicle 1. In such a case, the user can cancel the drive prohibition mode by performing a predetermined cancel operation after performing a normal door unlock operation (i.e., after switching from the first drive prohibition mode to the second drive prohibition mode). Further, the mode processing portion F340 may be configured to cancel the first driving prohibition mode when a predetermined cancel operation is detected in a state where the remote controller 200 corresponding to the vehicle 1 is present in the vehicle while the first driving prohibition mode is set. In this case, when the determination at step S102 in fig. 6 is negative, the same processing as that at step S108 and step S109 may be performed. Further, it may be configured such that the first driving prohibition mode is canceled by the mode processing portion F340 if it is determined that the remote controller 200 corresponding to the vehicle 1 is present in the vehicle when a predetermined cancel operation is detected.

According to the above-described embodiment, if the user gets on the vehicle 1 with the remote controller 200 in possession of the regular unlocking operation after the start of pre-air conditioning, the driving prohibition mode can be canceled by the user performing a predetermined cancel operation. In this case, since the operation of the internal combustion engine 10 is continued, the user can start the running of the vehicle 1 without performing the restart operation of the internal combustion engine 10. Further, since the door opening operation of the door is also invalidated in addition to the driving operation on the vehicle 1 until the normal unlocking operation is detected after the start of the pre-air conditioning, it is possible to suppress a situation in which the third party gets into the vehicle 1 improperly and a situation in which the third party starts the traveling of the vehicle 1 improperly. Further, since the driving operation for the vehicle 1 is invalidated after the detection of the normal unlocking operation, it is possible to suppress a case where the third party improperly starts the traveling of the vehicle 1 and a case where the family of the user or the like erroneously starts the traveling of the vehicle 1. Therefore, the balance of the convenience of the user and the safety of the vehicle 1 can be achieved.

Further, if the operation of the internal combustion engine 10 is automatically stopped when the prohibition operation is detected while the driving prohibition mode is being set, it is possible to more reliably suppress the third party from improperly starting the running of the vehicle 1. Further, if the restart operation of the internal combustion engine 10 is invalidated when the operation of the internal combustion engine 10 is automatically stopped, the third party cannot restart the internal combustion engine 10 improperly, so it is possible to further improve the safety of the vehicle 1.

In the present embodiment, an example in which heating in the vehicle interior is performed by pre-air conditioning is described, but the control device for a vehicle according to the present disclosure can be applied also to a case in which cooling in the vehicle interior is performed by pre-air conditioning. In short, the control device for a vehicle according to the present disclosure can be applied if the internal combustion engine needs to be operated when pre-air conditioning is performed.

In addition, from the viewpoint of suppressing the third party from improperly starting the travel of the Vehicle, the processing related to the setting of the driving prohibition mode and the processing related to the release of the driving prohibition mode may be applied to EV (Electric Vehicle), PHV (Plug-in Hybrid Vehicle), or FCV (Fuel Cell Vehicle). For example, by applying the processing relating to the setting of the prohibition mode and the processing relating to the cancellation of the driving prohibition mode according to the present disclosure to the EV, the PHV, or the FCV in which the drive system is switched to the operable state in accordance with the start of the pre-air conditioning, it is possible to suppress the vehicle from running improperly. In this case, when the prohibition operation is detected while the driving prohibition mode is being set, the process of turning off the drive system may be executed instead of the process of stopping the operation of the internal combustion engine. Further, after the pre-air conditioning is started, if the user takes the EV, the PHV, or the FCB with the remote controller in the possession of the regular unlocking operation, the driving prohibition mode may be canceled by the user performing a predetermined cancel operation. In this case, by continuing the operable state of the drive system, the user can start the traveling of the EV, the PHV, or the FCV without performing the restart operation of the drive system.
