[0002] As vehicle electrification continues to increase, numerous high- and low-voltage electrical devices are installed within vehicles, such as high-voltage drive motors and low-voltage onboard electronic systems. Traditional vehicle voltage control methods often rely on fixed distribution modes, making it difficult to flexibly adjust power according to the vehicle's real-time status. This often results in energy waste or insufficient power during critical times. For example, if the low-voltage system continues to consume power at its normal capacity during rapid acceleration, when high-voltage, high-power output is required, this will weaken the high-voltage power supply. Meanwhile, when the vehicle is parked or on standby, the high-voltage system's continued high-load operation increases energy consumption and is unable to adapt to complex and changing vehicle operating scenarios.

[0056] Step S302, determining current vehicle status information based on vehicle driving status data, vehicle-mounted device 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 pre-set, and vehicle state information corresponding to each vehicle driving state is determined. The driving state mapping information is established based on each vehicle driving state and the vehicle state information corresponding to each vehicle driving state. For example, the vehicle driving state can 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 specifically as follows:

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

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

[0061] 3) Vehicle low-speed congestion state 1: vehicle speed is less than 30 km / h, accelerator pedal change frequency is greater than a first preset frequency but less than a second preset power, battery power is greater than a first preset threshold, and vehicle-mounted equipment power is less than the first preset power;

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

[0063] 5) The third vehicle congestion state at low speed: 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 the 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 a mode mapping relationship table;

[0067] Step S403, determining a vehicle voltage distribution strategy according to the current voltage control mode;

[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 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 runs efficiently. At the same time, the vehicle's low-voltage power supply system is controlled to reduce the power supply 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 of the vehicle, the vehicle speed is lower than 30 km / h and the acceleration pedal is frequently changed. It is determined that the power demand is weakened and the energy saving demand is highlighted. The high-voltage power supply system of the vehicle is controlled to reduce the power supply power of the high-voltage power supply to 30% of the rated power, so as to reduce unnecessary energy consumption. At the same time, when the battery has sufficient power, the low-voltage power supply system of the vehicle is controlled to increase the power supply power of the low-voltage power supply, so that each vehicle-mounted electronic device can maintain normal operation during parking and waiting, improve the driving comfort, and realize the fine utilization of energy.

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

[0077] In some embodiments, optionally, the vehicle low-voltage power associated components can include but are not limited to vehicle driving motor, vehicle electric compressor, vehicle high-voltage distribution box, etc., and the vehicle low-voltage power associated components can include but are not limited to vehicle air conditioning system, vehicle body controller, vehicle lighting system, vehicle multimedia system and vehicle safety system (including various vehicle sensors and controllers) etc.

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

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

[0080] Step S602, according to the first priority and the first voltage distribution weight corresponding to each vehicle high-voltage power associated component, distributing the vehicle high-voltage to each vehicle high-voltage power associated component;

[0081] Step S603 : Distribute 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 associated component corresponds to the power priority level of each vehicle high-voltage power supply associated component. Assume that there are vehicle high-voltage power supply associated components 1 to 5, among which the first priority corresponding to vehicle high-voltage power supply associated component 1 is A1, the first priority corresponding to vehicle high-voltage power supply associated component 2 is A2, the first priority corresponding to vehicle high-voltage power supply associated component 3 is A3, the first priority corresponding to vehicle high-voltage power supply associated component 4 is A4, and the first priority corresponding to vehicle high-voltage power supply associated component 5 is A5. A2>A1>A4>A3>A5, then the output order of the vehicle high voltage is: vehicle high-voltage power supply associated 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 distribution weight of each vehicle high-voltage power supply associated component, the vehicle high voltage is distributed 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 distribution weight of each vehicle low-voltage power supply associated component, the vehicle low voltage is distributed to each vehicle low-voltage power supply associated component.
