Alternatively, the present embodiment is applied to a VCU (Vehicle control unit, vehicle controller) of a vehicle, i.e., a vehicle control device, for controlling a BMS (Battery Management System ) that controls power on or off of the vehicle by controlling a high-voltage contactor, the vehicle being provided with a door state sensor for detecting opening and closing of a door. Alternatively, the vehicle comprises a fuel cell vehicle, such as a hydrogen fuel cell vehicle.
Alternatively, the door status sensor may be a proximity switch status sensor, wherein the door status sensor is comprised of two parts, such as a detection element and an electronic processor, one part being mounted within the hydrogenation chamber, such as in a position proximate to the door, and the other part being mounted on the interior surface of the door. When the cabin door is opened, the two parts are separated, and the cabin door state sensor is in a connection state; when the cabin door is closed, the two parts approach, and the cabin door state sensor is in an open state at the moment, so that the opening and closing of the cabin door can be detected through the proximity switch type state sensor.
Optionally, the door status sensor feeds back the detected signal, such as the signal of the on state or the signal of the off state, to the VCU in real time through the wire harness, and the VCU determines the opening and closing of the door through the signal detected by the door status sensor, wherein when the door status sensor is in the off state, it is determined that the door is closed; when the door status sensor is in an on state, it is determined that the door is open. Optionally, the door state sensor may be a position sensor, and based on the position sensor, the position state of the door is acquired, where the position state includes a suspended state and a non-suspended state, and when the position state of the door is the suspended state, it is determined that the door is opened; and when the position state of the cabin door is a non-suspension state, judging that the cabin door is closed.
Alternatively, the door status sensor may be a photosensor, based on which the open status of the door is obtained, wherein the light intensity is different when the door is opened and closed, so that the opening or closing of the door can be determined according to the light intensity.
Optionally, if the cabin door is opened, a prompt message is generated and sent to an instrument of the vehicle, and the instrument displays characters for opening the cabin door to prompt a driver, for example, the prompt message is "fueling, do not drive". Optionally, if the door is closed, the meter has no hint information. When determining whether the instrument displays prompt information, only signals fed back by the cabin door state sensor are used as the basis.
Optionally, the operation state of the door state sensor includes normal or failure, and no matter whether the operation state of the door state sensor is normal or failure, when deciding whether to display the prompt information on the meter, the prompt information is "fuelling, do not run" only based on the door opening and closing fed back by the door state sensor.
Optionally, step S10 includes, before: after detecting a starting operation of a user, for example, ignition by screwing a key, performing self-checking by the VCU, determining whether the cabin door sensor fails according to the acquired signal of the cabin door sensor and whether a preset operation of a preset gear switch is received. Optionally, acquiring a signal detected by a cabin door state sensor; if the opening of the cabin door is determined according to the signal detected by the cabin door state sensor and the preset operation of a preset gear switch by a user is received, the cabin door state sensor is judged to have a fault.
Optionally, if the opening of the cabin door is determined according to the signal detected by the cabin door state sensor, acquiring the area where the vehicle is located; if the area where the vehicle is located is a preset area, judging that the cabin door state sensor has faults. Alternatively, the predetermined area is an area outside the fueling station, for example, an area outside the predetermined range of the fueling station. Alternatively, the preset area is a lane or the like.
Optionally, before step S20, the method further includes: in the process of preparing the vehicle to start, for example, when a driver turns a key to ignite, the vehicle is found to be incapable of loading high pressure, the actual opening and closing state of the cabin door input by a user is acquired, and if the cabin door is determined to be closed according to the actual opening and closing state, the cabin door state sensor is judged to have faults.
And step S20, when detecting that the running state of the cabin door state sensor is a fault, acquiring the current use state of the vehicle.
Alternatively, when the operation state of the cabin door state sensor is detected to be a fault, the cabin door opening and closing output by the cabin door state sensor may be wrong, and the opening and closing of the cabin door determined by the cabin door state sensor cannot be adopted at this time, so that the starting or running of the vehicle is controlled. The current use state of the vehicle needs to be acquired, and the vehicle is controlled according to the current use state.
Alternatively, the current usage state includes a stationary state or a running state of the vehicle, where the stationary state may include a parking state, and the running state may further include a running speed or a running gear, and the like.
Optionally, when detecting that the operation state of the cabin door state sensor is a fault, acquiring a signal detected by the cabin door state sensor; and when the cabin door is judged to be opened according to the signal detected by the cabin door state sensor, generating and outputting prompt information of cabin door opening.

And step S30, when the current use state is a static state and a preset operation of a preset gear switch is received, a high-voltage power-on instruction is sent to a battery management system so that the battery management system controls the vehicle to be powered on.
Alternatively, the preset operation of the preset gear switch may be a continuous pressing operation of a specific click gear switch, for example, a quick multiple-press double-flash button.
Optionally, when the current use state is a stationary state and the preset operation of the preset gear switch is received, the vehicle is required to be started at the moment, the command that the VCU prohibits high voltage is released, at the moment, the VCU can normally send a control command to the BMS, and the BMS controls the high voltage contactor to be closed, so that the vehicle can be at high voltage.
Optionally, while sending the control command to the BMS, the meter of the vehicle displays a prompt message, where the content of the prompt message is consistent with the opening and closing of the cabin door detected by the cabin door state sensor, for example, the prompt message is a text prompt of "fueling, do not travel". The damage to the normal starting requirement of the vehicle caused by the fault of the cabin door state sensor can be avoided, and a driver can be prompted to check and maintain the cabin door state sensor when the vehicle is convenient.
Optionally, the VCU sends a control instruction to the BMS, and after the BMS controls the high-voltage contactor to be powered on, the power-on state signal of the high-voltage contactor sent by the battery management system BMS is obtained; if the high-voltage power-on is judged to be successful according to the power-on state signal, acquiring a signal detected by a cabin door state sensor; if the opening of the cabin door is determined according to the signal detected by the cabin door state sensor, the prompt information that the cabin door is opened is generated and output. If the high-voltage power-on failure is judged according to the power-on state signal, a prompt message is generated to prompt a user to check other faults.
Referring to fig. 3, after a driver turns a key to ignite, the VCU performs a self-check, determines whether a door is opened according to a signal fed back by a door state sensor, displays a prompt message on an instrument when the door is determined to be opened, and transmits a high-voltage power-on command to the BMS when it is determined that a tap switch is continuously pressed down, and the BMS controls a high-voltage contactor to be closed to control the power-on of a vehicle. When the cabin door is judged to be closed, a high-voltage power-on instruction is sent to the BMS, and the BMS controls the high-voltage contactor to be closed to control the vehicle to be powered on.
In the technical scheme of the embodiment, the running state of the cabin door state sensor is detected; when detecting that the running state of the cabin door state sensor is a fault, acquiring the current use state of the vehicle; when the current use state is a static state and the preset operation of the preset gear switch is received, a high-voltage power-on instruction is sent to the battery management system, so that the battery management system controls the vehicle to be powered on. By detecting the running state of the cabin door state sensor, whether the vehicle can be controlled to be electrified or not is determined, the damage to the normal starting of the vehicle caused by the fault of the cabin door state sensor is avoided, and the safety of the starting of the vehicle is improved.
Referring to fig. 4 or fig. 3, fig. 4 is a second embodiment of the vehicle control method according to the present invention, based on the first embodiment, after the step S20, further includes:
step S40, when the current use state is a running state, acquiring a signal detected by the cabin door state sensor;
and S50, when the opening of the cabin door is judged according to the signal detected by the cabin door state sensor, generating and outputting prompt information of the opening of the cabin door.
Optionally, when the current use state of the vehicle is a driving state, the vehicle is indicated to be in the driving process, that is, the vehicle is powered on by high voltage and starts. If the burst cabin door state sensor fails and the cabin door state sensor judges that the cabin door is opened, the vehicle is not powered off at the moment, and the driving safety is ensured. At this time, the VCU does not transmit a high-voltage disconnection instruction to the BMS, and the vehicle can continue to travel normally, avoiding sudden loss of power of the vehicle.
Optionally, after judging that the cabin door is opened, generating and outputting prompt information of the cabin door opening, wherein the instrument of the vehicle displays the prompt information, for example, the prompt information is a text prompt of 'fueling and no driving'. Therefore, the damage to the normal running safety of the vehicle caused by the sensor fault can be avoided, and the driver can be prompted to check and maintain the cabin door state sensor when the vehicle is convenient, or further check the opening and closing conditions of the cabin door.
In the technical scheme of the embodiment, when the current use state is the running state, a signal detected by a cabin door state sensor is obtained; when the opening of the cabin door is judged according to the signal detected by the cabin door state sensor, prompt information of the opening of the cabin door is generated and output, so that the damage to the normal running safety of the vehicle caused by the sensor fault is avoided, and a driver can be prompted to further confirm the opening and closing condition of the cabin door so as to ensure the safe running.
Referring to fig. 5 or 3, fig. 5 is a third embodiment of the vehicle control method according to the present invention, and based on the first or second embodiment, the method further includes:
step S60, when the operation state of the cabin door state sensor is detected to be normal, determining the opening and closing of the cabin door according to the signal detected by the cabin door state sensor;
and step S70, if the cabin door is opened and the vehicle is in a running state, sending a power-off and power-on instruction to the battery management system after a preset time length so that the battery management system controls the vehicle to be powered off.
Alternatively, when the operation state of the door state sensor is normal, it indicates that the opening and closing of the door detected by the door state sensor is correct. Thus, the vehicle is controlled based on the signal detected by the door status sensor.
Optionally, if the cabin door is opened and the vehicle is in a stationary state, if the driver turns on the key to ignite, the VCU displays a prompt message after completing the self-test, for example, the prompt message is a text prompt of "fueling, do not run", and the driver is reminded to check and repair the cabin door when it is convenient. At this time, if the driver does not press the inching gear switch, the VCU does not send a high-voltage power-on instruction to the BMS, and the vehicle cannot drive away from the hydrogen station at high voltage. The driver looks at the actual open and closed state of the hatch. If the cabin door is indeed opened, the driver can close the cabin door and try to turn the key again to power up, and the vehicle is successfully powered up at high voltage and can run normally.
Optionally, if the cabin door is opened and the vehicle is in a running state, sending a power-off and power-on instruction to the battery management system after a preset duration, so that the battery management system controls the vehicle to be powered off to control the vehicle to stop, and safety accidents are avoided. Optionally, if a preset operation of the preset gear switch is received within a preset time period, the power-on disconnection instruction is not sent to the battery management system, so that the vehicle is prevented from being forcibly parked under the condition that the vehicle cannot be parked, and inconvenient traffic is caused.
Optionally, if the cabin door is opened and the vehicle is in a stationary state, detecting whether a preset operation of a preset gear switch is received; if the preset operation of the gear switch is received, a high-voltage power-on instruction is sent to a battery management system, so that the battery management system controls the vehicle to be powered on; alternatively, the preset operation of the preset gear switch may be a continuous pressing operation of a specific click gear switch, for example, a quick multiple-press double-flash button.
Optionally, if the cabin door 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 be powered on.
Optionally, if the cabin door is closed, detecting whether a preset operation of a preset gear switch is received; and if the preset operation of the preset gear switch is received, sending a high-voltage power-on instruction to the battery management system so that the battery management system controls the vehicle to be powered on. Alternatively, the preset operation of the preset gear switch may be a continuous pressing operation of a specific click gear switch, for example, a quick multiple-press double-flash button.
Optionally, the VCU sends a control instruction to the BMS, and after the BMS controls the high-voltage contactor to be powered on, the power-on state signal of the high-voltage contactor sent by the battery management system BMS is obtained; if the high-voltage power-on is judged to be successful according to the power-on state signal, acquiring a signal detected by a cabin door state sensor; if the opening of the cabin door is determined according to the signal detected by the cabin door state sensor, the prompt information that the cabin door is opened is generated and output. If the high-voltage power-on failure is judged according to the power-on state signal, a prompt message is generated to prompt a user to check other faults.
In the technical scheme of the embodiment, when the operation state of the cabin door state sensor is detected to be normal, the opening and closing of the cabin door are determined according to the signal detected by the cabin door state sensor; if the cabin door is opened and the vehicle is in a running state, sending a power-off and power-on instruction to the battery management system after a preset time period so that the battery management system controls the vehicle to be powered off. The detection result of the cabin door state sensor is prevented from damaging the normal running safety of the vehicle, and the power-off treatment is carried out on the vehicle after the preset duration of the opening and closing of the cabin door to ensure the safe running.
