[0060] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0061] Figure 1 is a flow chart of a method for controlling vehicle warm-up according to a first embodiment of the present invention. The vehicle is a fuel cell vehicle, including a fuel cell and a battery. As an embodiment of the present invention, Figure 1 As shown, the method for controlling vehicle warm-up may include:

[0062] Step S101 , in response to the temperature of the fuel cell being below freezing, controlling the vehicle to warm up.

[0063] The temperature of the fuel cell can be detected by a temperature sensor. If the temperature of the fuel cell is detected to be below the freezing point, that is, less than 0° C., the vehicle is controlled to warm up. Warming up means actively raising the temperature of the fuel cell so that the temperature of the fuel cell reaches a preset temperature range.

[0064] During the warm-up process, the battery supplies high voltage power to the hydrogen pump and air compressor to ensure smooth warm-up. The output power of the fuel cell during warm-up is less than the output power of the fuel cell during normal driving of the vehicle, that is, the fuel cell is in a low output state.

[0065] In step S101, it is determined whether the temperature of the fuel cell is below the freezing point in a normal pressure environment. When the vehicle is used in a plateau where the atmospheric pressure is lower, the freezing point in step S101 can be appropriately changed according to the atmospheric pressure of the use environment. The atmospheric pressure in the use environment can be directly detected by installing an atmospheric pressure sensor in the vehicle, or it can be inferred from the altitude of the place where the vehicle is located based on the vehicle's location information.

[0066] In step S101 , if it is determined that the temperature of the fuel cell exceeds the freezing point, it is determined that warm-up is not necessary, and the process ends, and the vehicle can travel normally.

[0067] Step S102 , in response to the vehicle warm-up time being less than a timeout threshold, determining whether the SOC consumed by the battery during the warm-up process is greater than or equal to a first SOC consumption threshold.

[0068] A timeout threshold may be preset. In step S102, the timer starts from the time when the vehicle starts to warm up, and it is determined at regular intervals whether the vehicle warm-up time is less than the timeout threshold. If the vehicle warm-up time does not exceed the timeout threshold (i.e., it is less than the timeout threshold), it is determined whether the SOC consumed by the battery during the warm-up process is greater than or equal to a first SOC consumption threshold. The first SOC consumption threshold is preset.

[0069] In step S102, if the vehicle warm-up time is greater than or equal to the timeout threshold (i.e., the system times out), the vehicle is controlled to stop warm-up operation and the battery is controlled as a power source to drive the vehicle's motor. In this case, the fuel cell is controlled to stop running, and only the battery is used as a power source to drive the vehicle's motor. At this time, the vehicle enters the retreat driving mode, in which the vehicle has basic driving functions, so that the user can drive the car into a room with a higher temperature and thaw it through natural heating of the ambient temperature.

[0070] Step S103 , in response to the SOC consumed by the battery during the warm-up process being greater than or equal to a first SOC consumption threshold, controlling the vehicle to stop warming up.

[0071] If the SOC consumed by the battery during the warm-up process is greater than or equal to the first SOC consumption threshold, the vehicle is controlled to stop warming up, that is, the fuel cell is controlled to stop running and the battery is controlled to stop supplying power to the heating component to avoid waste caused by excessive power output from the battery.

[0072] The embodiment of the present invention determines whether to control the vehicle to stop warming up based on whether the SOC consumed by the battery during the warming up process is greater than or equal to the SOC consumption threshold, which can avoid wasting the power output by the battery.

[0073] Figure 2 FIG. 1 is a flow chart of a method for controlling vehicle warm-up according to a second embodiment of the present invention. As another embodiment of the present invention, Figure 2 As shown, the method for controlling vehicle warm-up may include:

[0074] Step S201, determine whether the temperature of the fuel cell is below the freezing point; if so, execute step S202; if not, execute step S206.

[0075] Step S202, controlling the vehicle to warm up.

[0076] Step S203 , determining whether the warm-up time of the vehicle is less than a timeout threshold; if so, executing step 204 ; if not, executing step 207 .

[0077] Step S204, determining whether the SOC consumed by the battery during the warm-up process is greater than or equal to a first SOC consumption threshold; if so, executing step S205; if not, executing step S203.

[0078] Step S205, controlling the vehicle to stop warming up, prompting the user whether to warm up again, and in response to receiving the instruction submitted by the user to warm up again, executing step S201 again, or executing step S201 again after a predetermined time.

[0079] After controlling the vehicle to stop warming up, a prompt is issued to the user whether it is necessary to warm up again. If an instruction submitted by the user to warm up again is received, it is determined again whether the temperature of the fuel cell is below the freezing point. If so, the vehicle is controlled to warm up again. In other embodiments of the present invention, it is also possible not to issue a prompt to the user whether it is necessary to warm up again, but to start timing from the time when the vehicle is controlled to stop warming up, and after a predetermined time, it is determined again whether the temperature of the fuel cell is below the freezing point. If so, the vehicle is controlled to warm up again. If the warm-up effect is not ideal, continuing to warm up will result in a waste of electricity output by the fuel cell and the battery. Therefore, first controlling the vehicle to stop warming up and then controlling the vehicle to warm up again can improve the warm-up effect, thereby shortening the warm-up time and avoiding wasting electricity output by the fuel cell and the battery.

[0080] Step S206, controlling the vehicle to travel normally.

[0081] Step S207 , controlling the vehicle to stop warming up and controlling the battery as a power source to drive the motor of the vehicle.

[0082] The embodiment of the present invention determines whether to control the vehicle to stop warming up based on whether the SOC consumed by the battery during the warming up process is greater than or equal to the SOC consumption threshold, which can avoid wasting the power output by the battery.

[0083] Furthermore, the embodiment of the present invention prompts the user whether to warm up the engine again, which can help the user understand the reason why the vehicle cannot run normally, and the user can independently choose whether to warm up the engine again according to their own needs or environmental conditions.

[0084] It should be noted that, in step S207, the output power of the electric motor is limited, thereby limiting the driving speed of the vehicle, so that the driving speed of the vehicle is lower than the driving speed of the vehicle during normal driving.

[0085] Figure 3 FIG. 1 is a flow chart of a method for controlling vehicle warm-up according to a third embodiment of the present invention. Figure 3 As shown, the method for controlling vehicle warm-up may include:

[0086] Step S301, determine whether the temperature of the fuel cell is below the freezing point; if so, execute step S302; if not, execute step S308.

[0087] Step S302, controlling the vehicle to warm up.

[0088] Step S303, determining whether the warm-up time of the vehicle is less than a timeout threshold; if so, executing step S304; if not, executing step S309.

[0089] Step S304, determining whether the temperature of the fuel cell is less than the warm-up completion temperature; if so, executing step S305; if not, executing step S308.

[0090] Step S305, determining whether the temperature of the fuel cell is below the freezing point; if so, executing step S306; if not, executing step S303.

[0091] Step S306, determining whether the SOC consumed by the battery during the warm-up process is greater than or equal to a first SOC consumption threshold; if so, executing step S307; if not, executing step S303.

[0092] Step S307, controlling the vehicle to stop warming up, prompting the user whether to warm up again, and in response to receiving the instruction submitted by the user to warm up again, executing step S301 again, or executing step S301 again after a predetermined time.

[0093] Step S308, controlling the vehicle to travel normally.

[0094] Step S309, controlling the vehicle to stop warming up and controlling the battery as a power source to drive the motor of the vehicle.

[0095] The warm-up completion temperature may be preset, such as 40°C, 50°C or 65°C, etc. When the vehicle warm-up time is less than the timeout threshold, it is first determined whether the temperature of the fuel cell is less than the warm-up completion temperature. If not, the vehicle is controlled to run normally, thereby saving the power consumed by the battery and avoiding wasting power. When the temperature of the fuel cell is less than the warm-up completion temperature, S305 is continued.

[0096] Figure 4 FIG. 4 is a flow chart of a method for controlling vehicle warm-up according to a fourth embodiment of the present invention. Figure 4 As shown, the method for controlling vehicle warm-up may include:

[0097] Step S401, determine whether the temperature of the fuel cell is below the freezing point; if so, execute step S402; if not, execute step S409.

[0098] Step S402, controlling the vehicle to warm up.

[0099] Step S403, determining whether the warm-up time of the vehicle is less than a timeout threshold; if so, executing step S404; if not, executing step S410.

[0100] Step S404, determining whether the temperature of the fuel cell is less than the warm-up completion temperature; if so, executing step S405; if not, executing step S409.

[0101] Step S405, determining whether the temperature of the fuel cell is below the freezing point; if so, executing step S406; if not, executing step S403.

[0102] Step S406, determining whether the SOC consumed by the battery during the warm-up process is greater than or equal to a first SOC consumption threshold; if so, executing step S407; if not, executing step S403.

[0103] Step S407, determining whether the current SOC of the battery is greater than or equal to the SOC remaining threshold; if so, executing step S408; if not, executing step S410.

[0104] Step S408, controlling the vehicle to stop warming up, prompting the user whether to warm up again, and in response to receiving the instruction submitted by the user to warm up again, executing step S401 again, or executing step S401 again after a predetermined time.

[0105] Step S409, controlling the vehicle to travel normally.

[0106] Step S410, controlling the vehicle to stop warm-up operation and controlling the battery as a power source to drive the motor of the vehicle.

[0107] If the SOC consumed by the battery during the warm-up process is greater than or equal to a first SOC consumption threshold, it is determined whether the current SOC of the battery is greater than or equal to a SOC remaining threshold; if the current SOC of the battery is greater than or equal to the SOC remaining threshold, the vehicle is controlled to stop warming up and step S401 is executed again according to user needs or after a predetermined time; if the current SOC of the battery is less than the SOC remaining threshold, the vehicle is controlled to stop warming up and the battery is controlled as a power source to drive the vehicle's motor, so that the battery has sufficient SOC to allow the user to drive the car into a room with a higher temperature and thaw it through natural warming up of the ambient temperature.

[0108] In the case that the current SOC of the battery is greater than or equal to the SOC remaining threshold, the vehicle is controlled to stop warming up and step S401 is executed again according to user needs or after a predetermined time has passed, that is, the vehicle is controlled to perform a second warm-up. Similarly, the timing starts from the start of the second warm-up of the vehicle, and it is determined at intervals whether the second warm-up time of the vehicle is less than the timeout threshold. In the case that the second warm-up time of the vehicle does not exceed the timeout threshold, it is determined whether the temperature of the fuel cell is less than the warm-up completion temperature. In the case that the temperature of the fuel cell is less than the warm-up completion temperature, it is continued to be determined whether the temperature of the fuel cell is below the freezing point. In the case that the temperature of the fuel cell is below the freezing point, it is determined whether the SOC consumed by the battery during the second warm-up process is greater than or equal to the second SOC consumption threshold; in the case that the SOC consumed by the battery during the second warm-up process is greater than or equal to the second SOC consumption threshold, it is continued to be determined whether the current SOC of the battery is greater than or equal to the SOC remaining threshold. In the case that the current SOC of the battery is greater than or equal to the SOC remaining threshold, the vehicle is controlled to stop warming up and step S402 is executed again according to user needs or after a predetermined time has passed, that is, the vehicle is controlled to perform a third warm-up. And so on, I won’t go into details.

[0109] Optionally, the second SOC consumption threshold is less than or equal to the first SOC consumption threshold, so as to avoid wasting the power output by the battery. Similarly, during the third warm-up process, the third SOC consumption threshold is less than or equal to the second SOC consumption threshold, which will not be described in detail. Thus, it is possible to further avoid wasting the power output by the battery.
