Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the drawings are described in detail below.

The inventor finds in research on a conventional vehicle power-on control method that the conventional control method is relatively rough, namely after identity verification is completed, when it is detected that a vehicle door is opened, it is determined that a driving intention of a user exists, and a power-on action is completed immediately. However, in some application scenarios, a user may take things or rest in the vehicle when opening the vehicle door, and there is no driving intention, and this control method cannot accurately analyze the high-voltage power demand of the user, which affects the driving experience of the user.

Based on the above, the application provides a vehicle power-on control method, which discretely processes potential high-voltage power utilization requirements, and the method includes that when a user has driving intention, if it is detected that the pressure on a main driving seat is greater than or equal to a preset pressure threshold value and the condition duration is greater than a preset time threshold value, indicating that the user has driving intention, the vehicle is controlled to be powered on at high voltage. And the other mode is that the power consumption requirement of the high-voltage vehicle-mounted equipment and the remote control power-on requirement respond to a user instruction input by a user to control the vehicle to be powered on at high voltage. The other is that the power demand is determined according to the current working state of the battery, namely when the voltage of the starting battery is lower than a preset voltage threshold value, the vehicle is controlled to be electrified at high voltage so as to charge the starting battery; when the temperature of the power battery is lower than the preset temperature threshold value, in order to avoid damage to the power battery caused by low temperature, the high-voltage electrification of the vehicle is controlled, and the temperature of the battery is increased so as to prolong the service life of the battery.

Therefore, the method and the device have the advantages that the potential high-voltage power-on requirements are subjected to discrete visualization, each high-voltage power-on requirement is accurately analyzed and controlled, the use scene without high-voltage power-on is avoided, and more intelligent and convenient driving experience is brought to users.

In order to facilitate understanding of the technical solutions provided in the present application, a method for controlling power on of a vehicle provided in the present application will be described below with reference to the accompanying drawings.

Referring to fig. 1, which is a flowchart of a vehicle power-on control method provided in an embodiment of the present application, as shown in fig. 1, the method may include:

s101: and acquiring the pressure on the main driving seat detected by the pressure sensor.

In this embodiment, when the driver sits on the main driving seat, the driver is considered to have driving intention, and based on this scenario, a pressure sensor may be provided below the main driving seat, and the pressure signal may be used as a basis for powering on. Specifically, the pressure sensor detects the pressure on the main driving seat in real time, and the vehicle control unit can acquire the pressure value from the pressure sensor in real time.

S102: and when the pressure is greater than or equal to a preset pressure threshold value and the duration of the pressure greater than or equal to the preset pressure threshold value is greater than a preset time threshold value, controlling the vehicle to be electrified at high pressure.

After the vehicle control unit obtains the pressure on the main driving seat, the size of the pressure and a preset pressure threshold value at the moment is judged, and if the pressure on the current main driving seat is larger than or equal to the preset pressure threshold value, a driver is judged to exist at the moment. And then judging whether the continuous time is greater than a preset threshold value or not when the pressure on the current main driving seat is greater than or equal to the preset pressure threshold value, if so, determining that the user has driving intention, and controlling the vehicle to be electrified at high voltage.

In specific implementation, in order to further accurately analyze that the user really has the driving intention, whether the safety belt is opened or not can be further detected, if the safety belt is opened, the driving intention is determined to exist, and the vehicle is controlled to be powered on at high voltage. Specifically, a safety belt expansion coefficient is obtained, and when the safety belt expansion coefficient meets a preset expansion threshold value, the vehicle is controlled to be electrified at high voltage. Namely, when the safety belt expansion coefficient is larger than the preset expansion threshold value, the safety belt is tied by a user and the user wants to drive the vehicle, the vehicle is controlled to be powered on at high voltage. The seat belt stretching coefficient may be a length or a moment of the seat belt being stretched, and the specific expression form may be determined according to an actual situation, which is not limited herein.

In addition, before the pressure on the main driving seat of the pressure sensor is obtained, identity authentication can be performed firstly, and under the condition that the authentication is passed, the vehicle is controlled to be powered on at low voltage, so that a user can use part of vehicle-mounted equipment on the vehicle conveniently. Specifically, identity authentication is carried out based on a PEPS system or biological recognition, and when the authentication is passed, the vehicle is activated; and acquiring a vehicle door signal, and controlling the vehicle to be electrified at low voltage when the vehicle door signal is a vehicle door opening signal. Namely, after the vehicle completes identity authentication, the vehicle is activated firstly; and continuously monitoring the action of the vehicle door, and controlling the vehicle to be electrified at low voltage if the vehicle door is opened so as to facilitate a user to use the vehicle entertainment system. The biometric identification can be fingerprint identification, voice identification and other identification methods.

Referring to fig. 2, which is a flowchart of another vehicle power-on control method provided in the embodiment of the present application, as shown in fig. 2, the method may include:

s201: and acquiring a user instruction.

S202: and controlling the vehicle to be powered on at high voltage according to a user instruction.

In this embodiment, the controller may obtain a user instruction input by the user in real time, so as to execute a corresponding action according to the user instruction. The user instruction can be an instruction for starting the vehicle-mounted equipment, an automatic parking instruction or an upgrading instruction.

Specifically, when the user wants to start the in-vehicle device in the vehicle, a start-up-in-vehicle-device instruction may be input through the control panel or the voice assistant to start the in-vehicle device with the instruction. For example, when a passenger waits for a driver to drive a vehicle on the vehicle, or uses an air conditioner, a heater, or the like due to environmental factors, a user may input a user command through an air conditioner control panel or a Positive Temperature Coefficient heater (PTC) panel, or a user command to start the air conditioner, the PTC, through a voice assistant. And each vehicle-mounted equipment switch transmits high-voltage level to the vehicle control unit through a low-voltage line, and the vehicle control unit controls the vehicle to be powered on at high voltage after receiving the signals. As shown in fig. 3, a user may input a user instruction through the air conditioner control panel, the PTC control panel, and the intelligent voice terminal, respectively, and the control panel or the intelligent voice terminal outputs the user instruction to the vehicle control unit.

When a user wants to control the vehicle to automatically park in or out of the parking space, an automatic parking instruction and an automatic parking instruction can be sent to the vehicle through the remote control key, and when the controller receives the instructions, the controller controls the vehicle to be powered on at high voltage, so that the vehicle is controlled to execute corresponding operation. The automatic parking and the automatic parking are the automatic parking functions of the vehicle, and the automatic parking and the automatic driving out of the parking space of the vehicle can be realized through remote control.

When a user wants to perform software upgrading in a wireless transmission mode, remote upgrading can be performed through the remote control terminal T-BOX. When the controller receives an upgrading instruction sent by the remote control terminal, the vehicle is controlled to be powered on at high voltage so as to upgrade the software of the vehicle.

Referring to fig. 4, which is a flowchart of another vehicle power-on control method provided in the embodiment of the present application, as shown in fig. 4, the method may include:

s401: and acquiring the working voltage of the starting battery.

S402: and when the working voltage is lower than the preset voltage threshold, controlling the vehicle to be powered on at high voltage.

In this embodiment, since the starting battery is a key device for starting the vehicle, in order to ensure that the vehicle can be started normally, the working performance of the starting battery needs to be detected in real time, so as to ensure the service life of the battery. Specifically, when the controller monitors that the voltage of the battery is lower than a set voltage threshold, the controller controls the vehicle to be powered on at high voltage to charge the starting battery, otherwise, the vehicle cannot be started due to insufficient voltage of the starting battery.

It can be understood that, in a low-temperature environment, in order to ensure the normal operation of the power battery, the temperature of the power battery needs to be monitored in real time to avoid the damage of the low temperature to the power battery. The vehicle controller sets a self-checking period according to the reserved time, monitors the temperature of the power battery, and executes high-voltage electrification after the temperature is lower than a preset temperature threshold value, so that the temperature of the power battery is increased, and the battery is prevented from being damaged. Specifically, the working temperature of the power battery is obtained, and when the working temperature is lower than a preset temperature threshold, the vehicle is controlled to be powered on at high voltage. The power-on is a passive power-on of the vehicle with no driving intention, the power-on state is required to be displayed on an instrument and the power of the vehicle is required to be locked, namely, the vehicle is not allowed to be driven, and the power-on state is released after the power is supplied and shut down for a new time, so that the vehicle can be normally driven.

In a possible implementation manner, when the temperature of the power battery is detected, in order to ensure that the temperature of the power battery can reach the normal working temperature when a user drives the vehicle, the time for high-voltage power-on of the vehicle can be determined according to the reserved driving time and the current temperature of the power battery, so that the temperature of the power battery is just recovered to be normal before the user drives the vehicle, and the waste of high-voltage power utilization is avoided. Specifically, the reserved driving time is obtained, and the time for controlling the high-voltage power-on of the vehicle is determined according to the reserved driving time and the working temperature. For example, the reserved driving time set by the user is 8 am, the vehicle control unit determines that 30 minutes is needed to enable the temperature of the power battery to rise to the normal temperature according to the temperature of the power battery and the temperature rise rate, the vehicle high-voltage power-on time is controlled to be 7:30, and the vehicle control unit controls the vehicle to carry out high-voltage power-on when the vehicle control unit is 7:30, so that the temperature of the power battery is raised.

It should be noted that, the starting battery in this embodiment generally means that a 12V starting battery is a lead-acid battery, and provides low voltage for starting a vehicle; the power battery is a high-voltage power battery which provides main energy for a vehicle, generally a lithium ion battery, and the lithium ion battery is irreversibly damaged in a low-temperature environment, so that preheating is necessary if large-current discharge is required to be realized in the low-temperature environment (the large-current discharge is heated by using a heating film or other heating devices).

According to the embodiment, the potential high-voltage power utilization requirement is subjected to discrete processing, and one mode is that when the driving intention of the user exists, if the fact that the pressure on the main driving seat is greater than or equal to the preset pressure threshold value and the condition duration is greater than the preset time threshold value indicates that the driving intention of the user exists, the vehicle is controlled to be powered on at high voltage. And the other mode is that the power consumption requirement of the high-voltage vehicle-mounted equipment and the remote control power-on requirement respond to a user instruction input by a user to control the vehicle to be powered on at high voltage. The other is that the power demand is determined according to the current working state of the battery, namely when the voltage of the starting battery is lower than a preset voltage threshold value, the vehicle is controlled to be electrified at high voltage so as to charge the starting battery; when the temperature of the power battery is lower than the preset temperature threshold value, in order to avoid damage to the power battery caused by low temperature, the high-voltage electrification of the vehicle is controlled, and the temperature of the power battery is increased so as to prolong the service life of the power battery.
