The disclosed embodiment provides a fuel cell vehicle power-off control method, as shown in fig. 1, the method includes:
and S11, detecting the state of the personnel in the fuel cell vehicle.
The in-vehicle personnel state is used for representing whether personnel exist in the fuel cell vehicle or not.
And S12, acquiring the charging state information of the fuel cell vehicle.

And S13, judging whether the fuel cell vehicle meets a preset power-off condition or not at least according to the state of the people in the vehicle and the charging state information.
The power-off condition is a preset condition indicating that the driver leaves the vehicle but forgets to power off the vehicle. In other implementation manners, the present disclosure may further jointly determine whether the fuel cell vehicle satisfies the power-off condition according to the key detection state of the fuel cell vehicle, the vehicle occupant state, and the charging state information, which will be described in detail in other embodiments herein.
And S14, controlling the power system and the ignition switch of the fuel cell vehicle to be powered down under the condition that the fuel cell vehicle meets the power-down condition.
By adopting the method, the fuel cell vehicle can be controlled to automatically power off under the condition that the driver leaves the vehicle but forgets to power off the vehicle, so that the power resource of the fuel cell vehicle is saved, and the power supply of the storage battery and the power battery caused by excessive consumption of hydrogen of the fuel cell because the driver does not use the vehicle again for a long time is avoided.
In order to make the method provided by the embodiment of the present disclosure more easily understood by those skilled in the art, the method steps described above in fig. 1 are explained in detail below.
With respect to step S13, in a possible implementation manner of the embodiment of the present disclosure, the step may include: and determining that the fuel cell vehicle meets the power-off condition under the condition that the in-vehicle personnel state represents that the in-vehicle personnel of the fuel cell vehicle leave and the charging state information represents that the fuel cell vehicle is not in a charging state or the charging is finished.
In another possible implementation manner of the embodiment of the present disclosure, the fuel cell vehicle power-off control method provided in the embodiment of the present disclosure may further obtain a key detection state of the fuel cell vehicle before determining whether the fuel cell vehicle meets a preset power-off condition at least according to the vehicle interior personnel state and the charging state information; accordingly, step S13 may include: and determining that the fuel cell vehicle meets the power-off condition under the condition that the key detection state represents that a key leaves the vehicle, the in-vehicle personnel state represents that in-vehicle personnel of the fuel cell vehicle leave, and the charging state information represents that the fuel cell vehicle is not in a charging state or charging is completed.
For example, the detection of the state of the person in the vehicle according to the embodiment of the present disclosure may be performed by performing face recognition on an image acquired by an image acquisition device in the fuel cell vehicle, or may be performed by performing detection on a seat sensor disposed on a seat of the fuel cell vehicle, where for example, the seat sensor is a pressure sensor, and when a pressure value detected by the pressure sensor on each seat is smaller than a preset threshold value, it may be determined that the person in the vehicle has left, or it may be determined whether the person exists on the fuel cell vehicle jointly with the image acquired by the image acquisition device and a signal of the seat sensor.
In a possible implementation manner, in order to avoid that a person in the vehicle is triggered to automatically power off when the person leaves for a short time, and the vehicle use of a driver is affected, in the embodiment of the disclosure, when the state of the person in the vehicle is detected, the person existing in the fuel cell vehicle may be detected through an image acquisition device and/or a seat sensor in the fuel cell vehicle, and the person in the vehicle of the fuel cell vehicle is determined to have left under the condition that the person existing in the fuel cell vehicle is not detected within a first preset time period. That is, the embodiment of the present disclosure may determine that all the people in the vehicle have left only when the presence of people in the fuel cell vehicle is not detected for the first preset time period. The first preset time period may be set according to an actual requirement, for example, may be 5 minutes, which is not limited in this disclosure.
For example, the detection of the charging state in the embodiment of the present disclosure may be performed by detecting a current of a battery management system of the fuel cell vehicle, or may be performed by detecting a connection state of an on-board charger of the fuel cell vehicle, for example, if the on-board charger is not connected, it may be determined that the fuel cell vehicle is in the non-charging state, or the charging state of the fuel cell vehicle may be determined together with the current of the battery management system and the connection of the on-board charger.
For example, the detection of the key status in the embodiment of the present disclosure may be to sense whether the key leaves the vehicle by using a radio frequency identification technology to a vehicle body area control unit in the fuel cell vehicle, for example, the fuel cell vehicle may determine that the key does not leave the fuel cell vehicle by sensing that the key is in a vehicle body range through the radio frequency identification technology.
In one possible implementation manner, in order to avoid that a person in the vehicle leaves the key in the fuel cell vehicle to influence the vehicle use of a driver, when the key state is detected, if the obtained key detection state indicates that the key does not leave the vehicle, and under the condition that no personnel is detected in the fuel cell vehicle within a second preset time period, sending a message for prompting that a key is left in the vehicle to a mobile terminal bound with the fuel cell vehicle, the second preset time period may be set according to an actual requirement, and may be, for example, 5 minutes, which is not limited by the present disclosure, for example, in the case where the presence of a person in the fuel cell vehicle may not be detected for the first preset period of time as in the embodiment of the present disclosure described above, the second preset time length can be set to be greater than or equal to the first preset time length under the condition that the schemes that all the persons in the vehicle leave are determined to be combined.
Further, the step S14 may further include: judging whether a power system of the fuel cell vehicle is in a power-off state; and under the condition that the power system of the fuel cell vehicle is not in a power-off state, after delaying for a third preset time, powering off the power system and the ignition switch of the fuel cell vehicle. The second preset time period may be set according to actual requirements, for example, may be 10 minutes, which is not limited by the present disclosure, for example, in combination with the possible implementation manner of the second preset time period in the step S13, the third preset time period may be set to be longer than the second preset time period.
In addition, in a possible implementation manner of the embodiment of the disclosure, in a case where it is determined that the fuel cell vehicle satisfies the power-off condition, before controlling the power system of the fuel cell vehicle and the ignition switch to power off, it is determined whether the air conditioner of the fuel cell vehicle is in an on state, and in a case where the air conditioner of the fuel cell vehicle is in the on state, the air conditioner of the fuel cell vehicle is turned off. That is to say, under the condition that the fuel cell vehicle is judged to meet the preset power-off condition at least according to the personnel state and the charging state information in the vehicle, the air conditioner of the fuel cell vehicle is detected to be in an on state, the air conditioner of the fuel cell vehicle is turned off, and then the power system and the ignition switch of the fuel cell vehicle are controlled to be powered off.
