[0056] Step S302, determining current vehicle status information according to vehicle driving status data, vehicle-mounted equipment power usage information and vehicle battery status data;

[0057] Step S303: determining a current vehicle driving state that matches the current vehicle state information from a plurality of vehicle driving states according to the driving state mapping information.

[0058] In some embodiments, multiple vehicle driving states are preset, and the vehicle state information corresponding to each vehicle driving state is determined. According to each vehicle driving state and the vehicle state information corresponding to each vehicle driving state, the driving state mapping information is established. For example, the vehicle driving state may be a first state of high-speed cruising, a second state of high-speed cruising, a first state of low-speed congestion, a second state of low-speed congestion, or a third state of low-speed congestion, etc. The vehicle state information corresponding to each vehicle driving state is as follows:

[0059] 1) The first state of vehicle high-speed cruising: the vehicle speed is greater than 100 km / h, the frequency of accelerator pedal change is less than the first preset frequency, the first preset frequency is the frequency of accelerator pedal change in a stable driving state, the battery power is greater than the first preset threshold, and the power consumption of the vehicle-mounted equipment is less than the first preset power;

[0060] 2) The second state of high-speed cruising: the vehicle speed is greater than 100 km / h, the accelerator pedal change frequency is less than the first preset frequency, the first preset frequency is the accelerator pedal change frequency in a stable driving state, the battery power is greater than the first preset threshold, and the vehicle-mounted equipment power is greater than the first preset power;

[0061] 3) The first state of vehicle low-speed congestion: the vehicle speed is less than 30 km / h, the accelerator pedal change frequency is greater than the first preset frequency but less than the second preset power, the battery power is greater than the first preset threshold, and the power consumption of the vehicle-mounted equipment is less than the first preset power;

[0062] 4) The second state of vehicle low-speed congestion: the vehicle speed is less than 30 km / h, the frequency of accelerator pedal change is greater than the second preset frequency, the battery power is greater than the first preset threshold, and the power consumption of the vehicle-mounted equipment is greater than the first preset power;

[0063] 5) The third state of vehicle low-speed congestion: the vehicle speed is less than 30 km / h, the accelerator pedal change frequency is greater than the second preset frequency, the battery power is less than the first preset threshold, and the power consumption of the vehicle-mounted equipment is less than the first preset power.

[0064] In some embodiments, step S103 may include but is not limited to steps S401 to S404:

[0065] Step S401, obtaining a mode mapping relationship table; the mode mapping relationship table includes a plurality of preset voltage control modes and a vehicle driving state corresponding to each voltage control mode;

[0066] Step S402, determining a current voltage control mode corresponding to the current vehicle driving state from a plurality of voltage control modes according to the mode mapping relationship table;

[0068] Step S404: Control the vehicle voltage according to the vehicle voltage distribution strategy.

[0069] In some embodiments, a corresponding voltage control mode is set according to each vehicle driving state, and a mode mapping relationship table is established according to each voltage control mode and the vehicle driving state corresponding to each voltage control mode. Optionally, the mode mapping relationship table is shown in the following table:

[0070]

[0071] When the vehicle is in high-speed cruising state, the vehicle speed is stable at more than 100km / h, the accelerator pedal changes smoothly, and the battery power is sufficient. It is determined that the power demand is the main one at this time, and the vehicle's high-voltage power supply system is controlled to increase the high-voltage power supply power to 80% of the rated power, and output high voltage to the drive motor, so that the drive motor can run efficiently. At the same time, the vehicle's low-voltage power supply system is controlled to reduce the power supply power of the low-voltage power supply to the minimum limit for maintaining the operation of various on-board electronic equipment, that is, the minimum operating power, to avoid energy waste.

[0072] In the low-speed congestion state, the vehicle speed is less than 30km / h and it starts and stops frequently, and the accelerator pedal changes frequently. It is determined that the power demand is weakened at this time, and the energy-saving demand is highlighted. The vehicle's high-voltage power supply system is controlled to reduce the high-voltage power supply power to 30% of the rated power to reduce unnecessary energy consumption. At the same time, when the battery power is sufficient, the vehicle's low-voltage power supply system is controlled to increase the power supply power of the low-voltage power supply, so that various on-board electronic equipment can maintain normal operation during parking and waiting, improve driving comfort, and realize the refined utilization of energy.

[0076] Step S503, according to the vehicle high voltage power distribution strategy, determine the vehicle low voltage power output power, a number of vehicle low voltage power related components, and the second priority and second voltage distribution weight corresponding to each vehicle low voltage power related component.

[0077] In some embodiments, optionally, the vehicle low-voltage power supply-related components may include but are not limited to vehicle drive motors, vehicle electric compressors, vehicle high-voltage distribution boxes, etc., and the vehicle low-voltage power supply-related components may include but are not limited to vehicle air-conditioning systems, body controllers, vehicle lighting systems, vehicle multimedia systems, and vehicle safety systems (including a variety of vehicle sensors and controllers), etc.

[0078] In some embodiments, step S404 may include but is not limited to steps S601 to S603:

[0079] Step S601, outputting the corresponding vehicle high voltage and vehicle low voltage according to the vehicle high voltage power supply output power and the vehicle high voltage power supply output power, wherein the vehicle high voltage is controlled and outputted through the vehicle high voltage power supply system, and the vehicle low voltage is controlled and outputted through the vehicle low voltage power supply system;

[0081] Step S603 , distributing the vehicle low voltage to each vehicle low voltage power supply-related component according to the second priority and the second voltage distribution weight corresponding to each vehicle low voltage power supply-related component.

[0082] In some embodiments, the first priority corresponding to each vehicle high-voltage power supply-related component corresponds to the power priority level of each vehicle high-voltage power supply-related component. Assuming that there are vehicle high-voltage power supply-related components 1 to 5, among which the first priority corresponding to vehicle high-voltage power supply-related component 1 is A1, the first priority corresponding to vehicle high-voltage power supply-related component 2 is A2, the first priority corresponding to vehicle high-voltage power supply-related component 3 is A3, the first priority corresponding to vehicle high-voltage power supply-related component 4 is A4, and the first priority corresponding to vehicle high-voltage power supply-related component 5 is A5, A2>A1>A4>A3>A5, then the output order of the vehicle high voltage is: vehicle high-voltage power supply-related component 2-vehicle high-voltage power supply off Connecting component 1-vehicle high-voltage power supply associated component 4-vehicle high-voltage power supply associated component 3-vehicle high-voltage power supply associated component 5, then, according to the output order of the vehicle high voltage and the first voltage allocation weight of each vehicle high-voltage power supply associated component, the vehicle high voltage is allocated to each vehicle high-voltage power supply associated component. Similarly, the second priority corresponding to each vehicle low-voltage power supply associated component corresponds to the power priority level of each vehicle low-voltage power supply associated component. According to the second priority corresponding to each vehicle low-voltage power supply associated component, the output order of the vehicle low voltage is determined, and then, according to the output order of the vehicle low voltage and the second voltage allocation weight of each vehicle low-voltage power supply associated component, the vehicle low voltage is allocated to each vehicle low-voltage power supply associated component.
