[0050] Acquire signals detected by the hatch status sensor;

[0051] If the door is determined to be open based on the signal detected by the door status sensor, and a preset operation of the user's preset gear switch is received, then the door status sensor is determined to be faulty.

[0052] Optionally, the processor 101 can be used to call the vehicle control program stored in the memory 102 and perform the following operations:

[0053] If the door is determined to be open based on the signal detected by the door status sensor, the area where the vehicle is located can be obtained.

[0054] If the area where the vehicle is located is a preset area, then the door status sensor is determined to be faulty.

[0055] Optionally, the processor 101 can be used to call the vehicle control program stored in the memory 102 and perform the following operations:

[0056] When the operating status of the hatch status sensor is detected to be normal, the opening or closing of the hatch is determined based on the signal detected by the hatch status sensor.

[0057] If the hatch is open and the vehicle is in motion, a power-off command is sent to the battery management system after a preset time, so that the battery management system controls the vehicle to disconnect from power.

[0058] Optionally, the processor 101 can be used to call the vehicle control program stored in the memory 102 and perform the following operations:

[0059] If the hatch is open and the vehicle is stationary, then it is detected whether a preset operation of a preset gear switch has been received.

[0060] If a preset operation of the gear switch is received, a high-voltage power-on command is sent to the battery management system so that the battery management system controls the vehicle to power on.

[0061] If the hatch is closed, a high-voltage power-on command is sent to the battery management system so that the battery management system controls the vehicle to power on.

[0063] Obtain the power-on status signal of the high-voltage contactor sent by the battery management system;

[0064] If the high voltage is successfully powered on based on the power-on status signal, then the signal detected by the door status sensor is acquired.

[0065] If the hatch is determined to be open based on the signal detected by the hatch status sensor, a prompt message indicating that the hatch is open is generated and output.

[0066] Based on the hardware architecture of the vehicle control device described above, an embodiment of the vehicle control method of the present invention is proposed.

[0067] Reference Figure 2 or Figure 3 , Figure 2 This is a first embodiment of the vehicle control method of the present invention, the vehicle control method comprising the following steps:

[0068] Step S10: Detect the operating status of the hatch status sensor.

[0069] Optionally, this embodiment applies to the vehicle's VCU (Vehicle Control Unit), i.e., the vehicle control device. The VCU controls the BMS (Battery Management System), which controls the vehicle's power supply by controlling a high-voltage contactor. The vehicle is equipped with a door status sensor to detect the opening and closing of the doors. Optionally, the vehicle includes a fuel cell vehicle, such as a hydrogen fuel cell vehicle.

[0070] Optionally, the hatch status sensor can be a proximity switch type status sensor, which consists of two parts, such as a detection element and an electronic processor. One part is installed inside the hydrogen refueling tank, for example, close to the hatch, and the other part is installed on the inner surface of the hatch. When the hatch is open, the two parts separate, and the hatch status sensor is in the on state; when the hatch is closed, the two parts approach each other, and the hatch status sensor is in the off state. Therefore, the opening and closing of the hatch can be detected by the proximity switch type status sensor.

[0071] Optionally, the hatch status sensor feeds back the detected signals, such as an on or off signal, to the VCU in real time via a wiring harness. The VCU determines the opening or closing of the hatch based on the signals detected by the hatch status sensor. Specifically, when the hatch status sensor is off, the hatch is determined to be closed; when the hatch status sensor is on, the hatch is determined to be open. Optionally, the hatch status sensor can be a position sensor. Based on the position sensor, the position status of the hatch is obtained. The position status includes a suspended state and a non-suspended state. When the hatch is in a suspended state, the hatch is determined to be open; when the hatch is in a non-suspended state, the hatch is determined to be closed.

[0072] Optionally, the hatch status sensor can be a photosensitive sensor, which acquires the hatch's open state based on the photosensitive sensor. The light intensity is different when the hatch is open and closed, so the open or closed state of the hatch can be determined based on the light intensity.

[0073] Optionally, if the hatch is open, a prompt message is generated and sent to the vehicle's instrument panel, which displays the hatch opening information to the driver in text, such as "Refuel, do not drive." Optionally, if the hatch is closed, no prompt message is displayed on the instrument panel. The decision to display a prompt message on the instrument panel is based solely on the signal from the hatch status sensor.

[0074] Optionally, the operating status of the hatch status sensor may include normal or faulty. Regardless of whether the operating status of the hatch status sensor is normal or faulty, the decision to display a prompt message on the instrument panel is based solely on the hatch opening and closing status fed back by the hatch status sensor. For example, the prompt message may be "Refueling, do not drive".

[0075] Optionally, before step S10, the process includes: detecting a user's start operation, such as turning a key to ignite the ignition; the VCU performing a self-test; and then determining whether the door sensor is faulty based on the acquired door sensor signal and whether a preset operation of a preset gear switch is received. Optionally, the signal detected by the door status sensor is acquired; if the door is determined to be open based on the signal detected by the door status sensor, and a preset operation of a user's preset gear switch is received, then the door status sensor is determined to be faulty.

[0076] Optionally, if the door is determined to be open based on the signal detected by the door status sensor, the area where the vehicle is located is obtained; if the area where the vehicle is located is a preset area, then the door status sensor is determined to be faulty. Optionally, the preset area is an area outside the refueling station, for example, an area outside the preset range of a hydrogen refueling station. Optionally, the preset area is a lane, etc.

[0077] Optionally, before step S20, the method further includes: during the vehicle preparation to start, for example, when the driver turns the key to start the ignition and finds that the vehicle cannot access the high voltage, obtaining the actual opening and closing status of the hatch input by the user; if the hatch is determined to be closed based on the actual opening and closing status, then determining that the hatch status sensor is faulty.

[0078] Step S20: When the operating status of the door status sensor is detected to be faulty, the current usage status of the vehicle is obtained.

[0079] Optionally, when a fault is detected in the door status sensor, it indicates that the door opening / closing information output by the sensor may be incorrect. In this case, the door opening / closing information determined by the door status sensor cannot be used to control the vehicle's start or movement. It is necessary to obtain the vehicle's current usage status and control the vehicle based on that status.

[0080] Optionally, the current usage state includes the vehicle's stationary state or driving state. The stationary state may include the parked state, and the driving state may include the driving speed or driving gear, etc.

[0081] Optionally, when the operating status of the hatch status sensor is detected to be faulty, the signal detected by the hatch status sensor is acquired; when it is determined that the hatch is open based on the signal detected by the hatch status sensor, a prompt message indicating that the hatch is open is generated and output.

[0082] Optionally, the system receives signals collected by the hatch status sensor in real time and determines the time and / or location characteristics of the data collected by the hatch status sensor based on the time and / or location of the signals collected by the hatch status sensor; it selects the range of historical signal values ​​corresponding to the time and / or location characteristics from the sensor's historical database; and it determines whether the signals collected by the hatch status sensor are within the range of historical signal values: if yes, the hatch status sensor is determined to be fault-free; if no, the hatch status sensor is determined to be faulty.

[0083] Step S30: When the current usage state is a stationary state and a preset operation of a preset gear switch is received, a high-voltage power-on command is sent to the battery management system so that the battery management system controls the vehicle to power on.

[0084] Optionally, the preset operation of the preset gear switch can be a continuous pressing operation of a specific inching gear switch, such as rapidly pressing the hazard light button multiple times.

[0085] Optionally, when the current usage state is stationary and a preset operation of the preset gear switch is received, it indicates that the vehicle needs to be started at this time. The VCU's instruction to prohibit high voltage is released. At this time, the VCU can send control commands to the BMS normally, and the BMS controls the high voltage contactor to close, so that the vehicle can be connected to high voltage.

[0086] Optionally, while sending control commands to the BMS, the vehicle's instrument panel displays a prompt message. The content of the prompt message is consistent with the door opening / closing status detected by the door status sensor, for example, a message such as "Refueling, do not drive." This avoids jeopardizing the vehicle's normal starting needs due to a malfunctioning door status sensor, and also prompts the driver to inspect and maintain the door status sensor at their convenience.

[0087] Optionally, the VCU sends control commands to the BMS. After the BMS controls the high-voltage contactor to power on, it acquires the power-on status signal of the high-voltage contactor sent by the battery management system BMS. If the high-voltage power-on is successful based on the power-on status signal, it acquires the signal detected by the door status sensor. If the door is open based on the signal detected by the door status sensor, it generates and outputs a door-opened prompt message. If the high-voltage power-on fails based on the power-on status signal, it generates a prompt message to remind the user to check for other faults.

[0088] Reference Figure 3 After the driver turns the key to start the ignition, the VCU performs a self-check. Based on the signal from the door status sensor, the VCU determines whether the door is open. If the door is determined to be open, a prompt message is displayed on the instrument panel. Upon confirming that the jog switch has been continuously pressed, the VCU sends a high-voltage power-on command to the BMS. The BMS then controls the high-voltage contactor to close, powering the vehicle. If the door is determined to be closed, the VCU sends a high-voltage power-on command to the BMS, which in turn controls the high-voltage contactor to close, powering the vehicle.

[0089] In this embodiment, the operating status of the door status sensor is detected. When a fault is detected in the door status sensor, the current usage status of the vehicle is obtained. If the current usage status is a stationary state and a preset operation of a preset gear switch is received, a high-voltage power-on command is sent to the battery management system to enable the battery management system to control the vehicle to power on. By detecting the operating status of the door status sensor, it is determined whether the vehicle can be powered on, thus avoiding the harm caused by a faulty door status sensor to the normal starting of the vehicle and improving the safety of vehicle starting.

[0090] Reference Figure 4 or Figure 3 , Figure 4 This is a second embodiment of the vehicle control method of the present invention. Based on the first embodiment, after step S20, it further includes:

[0091] Step S40: When the current usage state is driving state, acquire the signal detected by the door state sensor;

[0092] Step S50: When it is determined that the hatch is open based on the signal detected by the hatch status sensor, a prompt message indicating that the hatch is open is generated and output.

[0093] Optionally, when the vehicle's current operating status is "driving," it means the vehicle is in motion, i.e., the vehicle is powered by high voltage and has started moving. If a sudden door status sensor malfunctions and the sensor determines the door is open, the vehicle will not be powered off to ensure driving safety. In this case, the VCU will not send a high-voltage disconnect command to the high-voltage contactor to the BMS, and the vehicle can continue to drive normally, preventing a sudden loss of power.

[0094] Optionally, after determining that the hatch is open, a hatch opening prompt message is generated and output, and the vehicle's instrument panel displays the prompt message, such as the text "Refuel, do not drive". This can both avoid the risk of sensor failure to the normal driving safety of the vehicle, and also prompt the driver to check and maintain the hatch status sensor at a convenient time, or prompt the driver to further check the opening and closing status of the hatch.

[0095] In the technical solution of this embodiment, when the current usage state is driving state, the signal detected by the door status sensor is acquired; when it is determined that the door is open according to the signal detected by the door status sensor, a prompt message for the door opening is generated and output, so as to avoid the sensor failure from causing harm to the normal driving safety of the vehicle, and can also prompt the driver to further confirm the opening and closing status of the door to ensure safe driving.

[0096] Reference Figure 5 or Figure 3 , Figure 5 In a third embodiment of the vehicle control method of the present invention, based on the first or second embodiment, the method further includes:

[0097] Step S60: When the operating status of the hatch status sensor is detected to be normal, the opening and closing of the hatch is determined according to the signal detected by the hatch status sensor.

[0098] Step S70: If the hatch is open and the vehicle is in motion, a power-off command is sent to the battery management system after a preset time, so that the battery management system controls the vehicle to disconnect from power.

[0099] Optionally, when the door status sensor is operating normally, it indicates that the door opening and closing detected by the sensor is correct. Therefore, the vehicle is controlled based on the signal detected by the door status sensor.

[0100] Optionally, if the hatch is open and the vehicle is stationary, if the driver turns the key to start the ignition, the VCU will complete its self-check and display a prompt message on the instrument panel, such as "Refueling, Do Not Drive," reminding the driver to check and maintain the hatch at a convenient time. At this time, if the driver does not press the jog switch, the VCU will not send a high-voltage power-on command to the BMS, and the vehicle cannot be driven away from the hydrogen refueling station. The driver checks the actual open / closed status of the hatch. If the hatch is indeed open, the driver will close the hatch and try turning the key to start the ignition again. If the vehicle is successfully powered on, it can be driven normally.

[0101] Optionally, if the hatch is open and the vehicle is in motion, a power-off command is sent to the battery management system after a preset time period, so that the battery management system controls the vehicle to cut off power and stop the vehicle to avoid a safety accident. Optionally, if a preset operation of a preset gear switch is received within the preset time period, a power-off command is not sent to the battery management system to avoid the vehicle being forced to stop when it cannot be stopped, causing traffic inconvenience.

[0102] Optionally, if the door is open and the vehicle is stationary, it is detected whether a preset operation of the preset gear switch has been received; if the preset operation of the gear switch is received, a high-voltage power-on command is sent to the battery management system so that the battery management system controls the vehicle to power on; optionally, the preset operation of the preset gear switch can be a continuous pressing operation of a specific inching gear switch, for example, pressing the hazard light button quickly and multiple times.

[0103] Optionally, if the hatch is closed, a high-voltage power-on command is sent to the battery management system so that the battery management system controls the vehicle to power on.

[0104] Optionally, if the door is closed, it checks whether a preset operation of a preset gear switch has been received; if a preset operation of the preset gear switch is received, a high-voltage power-on command is sent to the battery management system so that the battery management system controls the vehicle to power on. Optionally, the preset operation of the preset gear switch can be a continuous pressing operation of a specific inching gear switch, for example, rapidly pressing the hazard light button multiple times.

[0105] Optionally, the VCU sends control commands to the BMS. After the BMS controls the high-voltage contactor to power on, it acquires the power-on status signal of the high-voltage contactor sent by the battery management system BMS. If the high-voltage power-on is successful based on the power-on status signal, it acquires the signal detected by the door status sensor. If the door is open based on the signal detected by the door status sensor, it generates and outputs a door-opened prompt message. If the high-voltage power-on fails based on the power-on status signal, it generates a prompt message to remind the user to check for other faults.

[0106] In this embodiment, when the door status sensor detects that it is operating normally, the opening or closing of the door is determined based on the signal detected by the sensor. If the door is open and the vehicle is in motion, a power-off command is sent to the battery management system after a preset time, causing the battery management system to cut off the vehicle's power. This avoids the door status sensor's detection results from jeopardizing the vehicle's normal driving safety, and ensures safe driving by cutting off the vehicle's power after a preset time for door opening or closing.

[0107] The present invention also provides a vehicle control device, the vehicle control device including a memory, a processor, and a vehicle control program stored in the memory and executable on the processor, wherein when the vehicle control program is executed by the processor, it implements the various steps of the vehicle control method as described in the above embodiments.

One device of the door status sensor is located inside the cabin, and the other device is located at the door. When the two devices are far apart, the door status sensor is in an on state; when the two devices are close together, the door status sensor is in an off state.

[0109] The present invention also provides a computer-readable storage medium storing a vehicle control program, which, when executed by a processor, implements the various steps of the vehicle control method described in the above embodiments.
