Description

Technical Field

[0002] As global resources become increasingly scarce and environmental pollution becomes increasingly serious, environmental protection has become a topic of concern to the automotive industry. Hydrogen fuel cells, as a clean, efficient, and pollution-free electrochemical power generation device, have received widespread attention at home and abroad. At the same time, hydrogen fuel cell vehicles have become the mainstream of the current automotive industry development.

[0003] At present, when the fuel cell of a fuel cell vehicle is in a startable state, after the driver performs the power-on operation, the entire vehicle begins to execute the power-on process. At this time, the CCU (Central Computing Unit) will send a start instruction to the fuel cell. However, after the driver performs the power-off process during the fuel cell startup process, the fuel cell will continue to execute the startup process, and when the fuel cell is shut down after the fuel cell startup is completed, the entire vehicle can execute the power-off process. However, when the vehicle's power battery is low and the fuel cell needs to be started, the driver performs the power-on and power-off switching operation.

[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] To facilitate understanding of the technical solutions provided by the embodiments of the present application, the background technology involved in the embodiments of the present application will be described below.

[0040] As mentioned above, hydrogen fuel cell vehicles have become the mainstream of the current automotive industry. When the power battery of a fuel cell vehicle reaches the fuel cell start-up threshold, when the driver performs the power-on operation, the entire vehicle performs the power-on process, and the CCU will request the fuel cell to start. However, when the driver performs the power-off process during the startup of the fuel cell, the fuel cell will perform the startup process and when the fuel cell startup is completed, the fuel cell will be shut down and the entire vehicle can perform the power-off process. However, when the vehicle's power battery is low and the fuel cell needs to be started, the driver performs the power-on and power-off switching operation. The fuel cell not only needs to be started and stopped frequently, but the vehicle's power-on and power-off time are also relatively long, affecting the driver's driving experience.

[0041] The method provided in the embodiment of the present application can be executed by a controller, and the controller can control various functional modules of the vehicle, such as CCU (Central Computing Unit, central control switch module) and FCU (Fuel Control Unit, fuel control unit).

[0042] In order to solve this problem, a fuel cell state control method, device, equipment, storage medium and vehicle are provided in the embodiments of the present application. Obtain the power-on and power-off switching instructions during the fuel cell startup process; detect whether the power-on and power-off switching instructions meet the interruption condition; in response to meeting the interruption condition, adjust the fuel cell to a prohibited startup state within a first preset time; adjust the fuel cell state according to the vehicle usage state or the first preset time. Thus, when it is detected that the driver quickly presses the one-button start switch to switch between power on and off (for example, press four times within three minutes, power on → power off → power on → power off), the fuel cell startup is prohibited within N minutes to prevent the fuel cell from being frequently started and stopped and the vehicle from being powered on and off for a long time, thereby avoiding waste of resources and improving the efficiency and accuracy of power-on and power-off switching.

[0043] In order to facilitate understanding of the in-vehicle power generation method provided by the embodiment of the present application, the scenario example of the present application is explained below.

[0044] The following is an example of an embodiment to illustrate a fuel cell state control method provided by the present application. Figure 1 , which is a flow chart of a fuel cell state control method provided in an embodiment of the present application, including:

[0045] S101: Obtaining power-on and power-off switching instructions during the fuel cell startup process.

[0046] The power-on and power-off switching command is a control command issued by the person in the vehicle for controlling the power-on and power-off. For example, during the startup process of the fuel cell, when the CCU recognizes that the driver quickly presses the one-button start switch four times within 15 seconds (currently in the state of power-on → power-off → power-on → power-off), the controller obtains the power-on and power-off switching command issued by the person in the vehicle, and the number of switching indicated by the current power-on and power-off switching command is 4.

[0047] S102: Detect whether the power-on / power-off switching instruction satisfies an interruption condition.

[0048] The interruption condition is that the number of switching times indicated by the power-on and power-off switching instruction is greater than the quantity threshold within the third preset time. According to the power-on and power-off switching instruction obtained in the above steps, the instruction indicates that the number of switching times within 15 seconds is 4 times. If the current interruption condition is set to switch 2 times within 15 seconds, the current power-on and power-off switching instruction meets the interruption condition.

[0049] S103: In response to the interruption condition being met, adjusting the fuel cell to a startup prohibition state within a first preset time.

[0050] When the obtained power-on and power-off switching meets the interruption condition, the controller adjusts the fuel cell to a startup-prohibited state, and the duration of this state is a first preset time. The length of the first preset time can be set according to actual needs and can be set by the system or the driver, and is not limited here.

[0051] S104: adjusting the fuel cell state according to the vehicle use state or the first preset time.

[0052] The vehicle usage status may include vehicle speed status and function execution status.

[0053] In actual application scenarios, after the fuel cell is adjusted to the prohibited start state, the controller can control the timing module to start timing, and before the first preset time ends, the fuel cell is controlled to remain in the prohibited start locking state.

[0054] In the first case, after the first preset time ends, the prohibited start-up state of the fuel cell is released and the fuel cell is adjusted to a start-able state.

[0055] In the second case, when the CCU prohibits the start-up of the fuel cell, the current vehicle speed is obtained to determine whether the vehicle speed meets the vehicle speed condition, where the vehicle speed condition is that the vehicle is in a driving state and the vehicle speed is continuously greater than the speed threshold within a second preset time interval; for example, if the CCU detects that the vehicle speed is greater than 2km / h for 5 consecutive seconds and the current vehicle is still in a driving state, it is determined that the driver has a need to use the vehicle, and the fuel cell is controlled to be adjusted to a startable state.

[0056] In the third case, when the CCU prohibits the start-up of the fuel cell, the function execution status of the current vehicle is obtained to detect whether the vehicle speed meets the functional conditions. The functional conditions are that the discharge function of the vehicle is turned on and executed. For example, it is detected that the vehicle executes the V2L discharge function. In response to the vehicle meeting the functional conditions, the fuel cell is adjusted to a startable state.

[0057] In actual application scenarios, when the fuel cell has been adjusted to a startable state, the CCU central control switch module requests the fuel cell to start and issues a start command. For example, when the power battery is low and not in a charging state, the person in the car presses the one-button start button, which issues a start command and the CCU requests the fuel cell to start.

[0058] A fuel cell state control method is provided in an embodiment of the present application. When it is detected that the driver quickly presses the one-button start switch to switch between on and off power, the fuel cell is set to be prohibited from starting within N minutes. If it is detected that there is a demand for the current vehicle or the countdown of the first preset time is over when the fuel cell is in the prohibited start state, fuel-electric start is allowed. Preventing the fuel cell from being frequently started and stopped and the vehicle from being powered on and off for a long time, thus avoiding waste of resources and improving the efficiency and accuracy of switching between on and off power. Solving the problem of the time required to start the fuel cell vehicle when the power battery is low and reducing the power consumption of the power battery. Preventing the fuel cell from being frequently started and stopped when the power battery is low and the fuel cell vehicle needs to be started increases the service life of the fuel cell.

[0059] The following is an example of a fuel cell state control method provided by the present application. Figure 2 , Figure 2 A flow chart of a fuel cell state control method provided in an embodiment of the present application includes:

[0060] S201: Obtain a power-on request.

[0061] The person in the car initiates a power-on request. In actual application scenarios, the initiation time, initiation method, and initiator of the power-on request can be recorded in the database to generate a driving log.

[0062] S202: Detect whether the vehicle meets the power-on condition.

[0063] The power-on condition is that the SOC value of the power battery is less than the fuel cell startup threshold. During the application process, the current power battery power is obtained to determine whether the current power battery SOC value is less than the fuel cell startup threshold.

[0064] S203: In response to the vehicle meeting a power-on condition, starting the fuel cell.

[0065] When the power battery is lower than the fuel-electric start threshold, the CCU requests the fuel cell to start, otherwise the vehicle is powered and driven purely on electricity.

[0066] S204, obtaining power-on and power-off switching instructions during the fuel cell startup process.

[0067] According to the aforementioned process, the fuel cell is already in the startup state, and in the current startup process, a power-on and power-off switching instruction issued by the occupant of the vehicle is obtained.

[0068] S205: Detect whether the power-on and power-off switching instruction satisfies an interruption condition.

[0069] Detect whether the current power-on and power-off switching instructions meet the preset interruption conditions. In actual application scenarios, the content of the interruption conditions can be set according to actual needs and can be defined by the driver. There is no restriction on the adaptive modification of this condition in this application.

[0070] S206 , in response to satisfying the interruption condition, adjusting the fuel cell to a startup prohibition state within a first preset time.

[0071] Among them, the first preset time can be set and adjusted according to actual needs.

[0072] S207: Adjust the fuel cell state according to the vehicle usage state or the first preset time.

[0073] The vehicle use status is used to display whether there is a demand for the vehicle during the current use of the vehicle, so as to determine whether it is necessary to allow the fuel cell to start within the first preset time.
