Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a flowchart of an electronic lock control method for a vehicle according to an embodiment of the present invention is shown. The electronic lock control method for the vehicle provided by the embodiment of the invention can be executed by a vehicle-mounted charger and also can be executed by an electronic lock state machine arranged in the vehicle-mounted charger.

The electronic lock control method of the vehicle specifically comprises the following steps of S11 to S13:

s11, receiving an electronic lock instruction sent by the vehicle control unit; the electronic lock instruction comprises an electronic lock locking instruction and an electronic lock unlocking instruction;

s12, executing a driving detection operation corresponding to the electronic lock instruction; the driving detection operation is used for sending a driving signal corresponding to the electronic lock instruction to the electronic lock and then detecting the current running state fed back by the electronic lock; the running state comprises a locking state or an unlocking state;

and S13, reporting the state mode of the electronic lock according to the current running state fed back by the electronic lock.

Specifically, the vehicle control unit of the vehicle generates a corresponding electronic lock instruction according to the current charging or discharging requirement of the vehicle and sends the electronic lock instruction to the vehicle-mounted charger. For example, when the electric quantity of the vehicle battery is less than a preset electric quantity lower limit threshold value and it is detected that a charging gun is plugged in a charging interface of the vehicle, a locking instruction of the electronic lock is generated and issued to a vehicle-mounted charger, so that the vehicle-mounted charger can drive the electronic lock to perform a locking action and control the vehicle to enter a charging state and the like. For another example, when the electric quantity of the vehicle battery reaches a preset electric quantity upper limit threshold value, or when the current vehicle is not in the process of charging or discharging, an electronic lock unlocking instruction is generated and the vehicle-mounted charger is issued, so that the vehicle-mounted charger can drive the electronic lock to execute an unlocking action, and a user can pull down the charging gun smoothly.

It is to be understood that the situation that the vehicle control unit sends the electronic lock command is not limited to the above scenario, and is not specifically limited herein.

Further, after receiving an electronic lock instruction sent by the vehicle control unit, the vehicle-mounted charger sends a driving signal corresponding to the electronic lock instruction to the electronic lock. The driving signal comprises a locking driving signal corresponding to the electronic lock locking instruction and used for driving the electronic lock to execute a locking action, and the driving signal also comprises an unlocking driving signal corresponding to the electronic lock unlocking instruction and used for driving the electronic lock to execute an unlocking action.

It should be noted that the electronic lock may continuously or periodically feed back the running state of the electronic lock to the vehicle-mounted charger. The operation state comprises two states, namely an unlocking state and a locking state. On the basis, after the vehicle-mounted charger sends a corresponding driving signal to the electronic lock, the current running state fed back by the electronic lock is detected, and then the state mode of the electronic lock is reported according to the current running state fed back by the electronic lock.

The embodiment of the invention provides a vehicle electronic lock control method, wherein after receiving an electronic lock instruction sent by a vehicle controller, a vehicle-mounted charger sends a driving signal corresponding to the electronic lock instruction to an electronic lock so as to drive the electronic lock to perform a locking action or an unlocking action. And then, the vehicle-mounted charger detects the operation state fed back by the electronic lock again, and reports the state mode of the electronic lock according to the operation state fed back by the electronic lock. The embodiment of the invention adopts the control logic of first driving and then detecting, can effectively avoid the situation that the electronic lock cannot normally lock or unlock according to the instruction sent by the whole vehicle controller by the electronic lock because the operation state fed back by the quality problem of the electronic lock is wrong under the control logic of firstly detecting the operation state of the electronic lock and then determining whether to send the driving signal according to the operation state, and can effectively improve the reliability and robustness of the driving control logic of the electronic lock, thereby better ensuring the personal safety of a user and improving the vehicle using experience of the user.

As a preferred implementation manner, refer to fig. 2, which is a schematic relationship diagram of status modes of an electronic lock in an embodiment of the present invention. The state modes of the electronic lock comprise a default state mode, a locking state mode and an unlocking state mode. The locking state mode is divided into a locking state mode, a locked state mode and a locking fault state mode; the unlock state mode is further classified into an unlock-in-state mode, an unlocked state mode, and an unlock failure state mode.

Preferably, before the step S11, the method further includes a step S11':

and S11', reporting that the state mode of the electronic lock is a default state mode when the whole vehicle is powered on.

In the embodiment of the invention, when the whole vehicle is powered on, the running state of the current electronic lock is not detected, so a default mode, namely the default mode, is preset and reported and displayed by the electronic lock state machine when the whole vehicle is powered on.

When the vehicle-mounted charger receives an electronic lock instruction of the vehicle control unit, if the electronic lock instruction is an electronic lock locking instruction, reporting that a state mode of the electronic lock is a specific state mode in a locking state mode according to an actual driving detection operation result. And if the electronic lock instruction is an electronic lock unlocking instruction, reporting that the state mode of the electronic lock is a specific state mode in the unlocking state modes according to an actual drive detection operation result.

Referring to fig. 3, a flow chart of a method for controlling an electronic lock of a vehicle according to a second embodiment of the present invention is shown as a preferred implementation manner. The electronic lock control method for the vehicle provided by the second embodiment of the present invention is specifically executed through steps S21 to S23:

and S21, receiving an electronic lock locking instruction sent by the vehicle control unit, and reporting that the state mode of the electronic lock is a locking state mode.

S22, executing locking drive detection operation; the locking drive detection operation is: sending a locking driving signal to the electronic lock to drive the electronic lock to be locked; and after a first preset time, detecting the current running state fed back by the electronic lock.

And S23, if the current operation state fed back by the electronic lock is detected to be the locking state, reporting that the state mode of the electronic lock is the locked state mode.

In an embodiment of the present invention, if the electronic lock command sent by the vehicle control unit is an electronic lock locking command, the driving detection operation corresponding to the electronic lock command is a locking driving detection operation.

Fig. 4 is a schematic diagram of locking control of an electronic lock according to an embodiment of the present invention. The vehicle control unit sends an electronic lock locking instruction to the vehicle-mounted charger, the current charging gun is in a connected state, and the vehicle-mounted charger reports that the state mode of the electronic lock is a locking state mode after receiving the electronic lock locking instruction. And then, the vehicle-mounted charger sends a first locking driving signal to the electronic lock so as to drive the electronic lock to execute a locking action. The driving time of the lock driving signal is TBD1 ms. After the driving time is over, and after a waiting time TBD2ms passes, the vehicle-mounted charger detects the current operation state fed back by the electronic lock, and if the operation state fed back by the electronic lock is the locking state, it indicates that the locking driving is successful at this time, or the electronic lock itself is in the locking state. And reporting that the state mode of the electronic lock is the locked state mode according to the locked state fed back by the electronic lock.

The first preset time is the sum of the driving time and the waiting time. The first preset time, the driving time and the waiting time are all set according to actual conditions, and are not specifically limited herein. Preferably, the waiting time is slightly greater than the driving time. The reason why the waiting time is set to be slightly longer is to avoid the situation where the feedback signal is jittered when the electronic lock is actually operated.

In another case, the electronic lock control method for a vehicle according to the second embodiment of the present invention further includes step S24:

and S24, if the current running state fed back by the electronic lock is detected to be the unlocking state, the locking driving detection operation is executed again.

Fig. 5 is a schematic diagram of locking control of an electronic lock according to another embodiment of the present invention. And after a first preset time period passes, the vehicle-mounted charger detects the current running state fed back by the electronic lock, and if the running state fed back by the electronic lock is an unlocked state, the current running state shows that the locking driving fails, or the electronic lock is in a locked state but the fed back running state is wrong. At this time, in order to increase the success rate of driving the electronic lock to be locked, the vehicle-mounted charger jumps to step S22, and re-executes the locking driving detection operation, so as to report that the state mode of the electronic lock is the locked state mode when detecting that the current operation state fed back by the electronic lock is the locked state.

Further, after the step S24, the method further includes steps S25 and S26:

s25, counting the re-execution of the lock drive detection operation;

s26, when the number of times of re-executing the locking driving detection operation reaches a first preset number of times and it is detected that the current running state fed back by the electronic lock is an unlocked state, stopping executing the locking driving detection operation and reporting that the state mode of the electronic lock is a locking fault state mode.

The vehicle-mounted charger calculates the number of times T1 for which the lock drive detection operation is to be re-executed. For example, if the vehicle-mounted charger receives an electronic lock locking command of the vehicle control unit and then transmits a locking driving signal to the electronic lock, the locking driving signal is defined as a first locking driving signal, and when the locking driving detection operation is re-executed, the transmitted locking driving signal is defined as a second locking driving signal, and at this time, the number of times T1 that the locking driving detection operation is re-executed is defined as one, that is, T1 is 1.

When the number T1 of times of re-executing the locking driving detection operation reaches a first preset number and it is detected that the current running state fed back by the electronic lock is an unlocked state, the execution of the locking driving detection operation is stopped, and the state mode of the electronic lock is reported as a locking fault state mode.

For example, if the first preset number of times is set to 4, then when the number of times T1 of re-executing the locking driving detection operation is 4, that is, after the vehicle-mounted charger has sent the fifth locking driving signal, if it is detected that the current operating state fed back by the electronic lock is still the unlocked state, the vehicle-mounted charger does not execute the locking driving detection operation any more, and reports that the state mode of the electronic lock is the locking fault state mode according to the unlocked state fed back by the electronic lock, so that the user can check and maintain the electronic lock according to the displayed locking fault state mode.

By adopting the technical means of the embodiment of the invention, the reported locking state mode of the electronic lock is divided into three modes of locking, locked and locking fault, the electronic lock is driven to execute corresponding locking action through the control logic which is driven and detected firstly, and the current state mode of the electronic lock is reported according to the multiple detection results of the running state of the electronic lock, so that the reliability and robustness of the driving control logic of the electronic lock can be effectively improved, the state mode of the electronic lock can be reported more accurately, the electronic lock is convenient for a user to check and overhaul, and the vehicle using experience of the user is improved.

Preferably, in step S26, that is, after the status mode of the electronic lock is reported as the locking fault status mode, if an electronic lock unlocking instruction sent by the vehicle control unit is received, the status mode of the electronic lock is reported as the unlocking status mode, and the original locking fault status mode is released. The specific status mode of the reported unlocked status modes is contingent on the specific situation.

By adopting the technical means of the embodiment of the invention, when the electronic lock is in the locking fault, the unlocking instruction of the vehicle control unit is received again, and the locking fault is automatically cleared, so that the locking fault of the electronic lock can be eliminated through vehicle control, and the control flexibility of the electronic lock is improved.

Referring to fig. 6, a flow chart of an electronic lock control method for a vehicle according to a third embodiment of the present invention is shown as a preferred implementation manner. In the electronic lock control method for a vehicle provided by the third embodiment of the present invention,

specifically, the steps S31 to S33 are performed:

and S31, receiving an electronic lock unlocking instruction sent by the vehicle control unit, and reporting that the state mode of the electronic lock is an unlocking state mode.

S32, executing unlocking drive detection operation; the unlock drive detection operation is: sending an unlocking driving signal to the electronic lock to drive the electronic lock to unlock; and after a second preset time period, detecting the current running state fed back by the electronic lock.

And S33, reporting that the state mode of the electronic lock is the unlocked state mode if the current running state fed back by the electronic lock is detected to be the unlocked state.

In the embodiment of the invention, the electronic lock instruction sent by the vehicle control unit is an electronic lock unlocking instruction, and the drive detection operation corresponding to the electronic lock instruction is an unlocking drive detection operation.

The vehicle control unit sends an electronic lock unlocking instruction to the vehicle-mounted charger, and the vehicle-mounted charger reports that the state mode of the electronic lock is an unlocking state mode after receiving the electronic lock unlocking instruction. And then, the vehicle-mounted charger sends a first unlocking driving signal to the electronic lock to drive the electronic lock to execute an unlocking action. The driving time of the unlocking driving signal is TBD' 1 ms. After the driving time is over, and after a waiting time TBD' 2ms passes, the vehicle-mounted charger detects the current operation state fed back by the electronic lock, and if the operation state fed back by the electronic lock is an unlocking state, it indicates that the unlocking driving is successful at the moment, or the electronic lock is in the unlocking state. And reporting that the state mode of the electronic lock is the unlocked state mode according to the unlocked state fed back by the electronic lock.

The second preset time is the sum of the driving time and the waiting time. The second preset time, the driving time and the waiting time are all set according to actual conditions, and are not specifically limited herein. Preferably, the waiting time is slightly longer than the driving time, and the second preset time period is equal to the first preset time period.

In another case, the electronic lock control method for a vehicle according to the third embodiment of the present invention further includes step S34:

and S34, if the current running state fed back by the electronic lock is detected to be the locked state, re-executing the unlocking driving detection operation.

And after sending a first unlocking driving signal to the electronic lock and after the second preset time, the vehicle-mounted charger detects the current running state fed back by the electronic lock, and if the running state fed back by the electronic lock is a locked state, the unlocking driving fails at the moment, or the electronic lock is in an unlocked state but the fed back running state is wrong. At this time, in order to improve the success rate of driving the electronic lock to unlock, the vehicle-mounted charger jumps to step S32 to re-execute the unlocking driving detection operation, so that when it is detected that the current running state fed back by the electronic lock is the unlocked state, the state mode of the electronic lock is reported as the unlocked state mode.

Further, after the step S34, the method further includes steps S35 and S36:

s35, counting the re-execution of the unlock drive detection operation;

and S36, when the number of times of re-executing the unlocking driving detection operation reaches a second preset number of times and the current running state fed back by the electronic lock is detected to be a locking state, stopping executing the unlocking driving detection operation and reporting that the state mode of the electronic lock is an unlocking fault state mode.

The vehicle-mounted charger calculates the number of times T2 for which the unlock drive detection operation is re-executed. For example, after receiving an electronic lock unlocking instruction of the vehicle control unit, the vehicle-mounted charger records an unlocking driving signal sent to the electronic lock as a first unlocking driving signal, and when the unlocking driving detection operation is re-executed, the vehicle-mounted charger records the sent unlocking driving signal as a second unlocking driving signal, and at this time, the number of times T2 of re-executing the unlocking driving detection operation is recorded as one time, that is, T2 is 1.

When the number of times T2 of re-executing the unlocking driving detection operation reaches a second preset number of times and it is detected that the current running state fed back by the electronic lock is a locked state, the execution of the unlocking driving detection operation is stopped, and the state mode of the electronic lock is reported as an unlocking fault state mode.

For example, if the second preset number of times is set to 4, then when the number of times T2 of re-executing the unlocking driving detection operation is 4, that is, after the vehicle-mounted charger has sent the fifth unlocking driving signal, if it is detected that the current operating state fed back by the electronic lock is still the locked state, the vehicle-mounted charger does not execute the unlocking driving detection operation any more, and reports the state mode of the electronic lock as the unlocking fault state mode according to the locked state fed back by the electronic lock, so that the user can check and maintain the electronic lock according to the displayed unlocking fault state mode.
