and the management module is used for controlling the plurality of electric equipment to execute corresponding actions according to the actual working state, calculating the total power consumption of the current electric equipment of the whole vehicle, and sending the total power consumption to the energy management module of the vehicle so as to manage the low-voltage power consumption in the current running state through the energy management module, so that the low-voltage power consumption is smaller than a preset threshold value.
7. The apparatus of claim 6, wherein before determining the actual operating states of the plurality of electric devices corresponding to the optimal scene mode from the preset scene-electric device table based on the optimal scene mode, the matching module is further configured to:
constructing a plurality of use scenes based on the use condition of the target vehicle, and determining a whole vehicle function demand list and a scene questionnaire of each use scene;
based on the finished vehicle function demand list and the scene questionnaire, performing work demand decomposition according to a plurality of electronic electrical systems of the target vehicle to obtain a scene-equipment work demand list;
classifying the electronic appliance systems according to the characteristics of the electronic appliances in the electronic appliance systems based on preset regulations and safety conditions, and obtaining the preset scene-electric appliance list according to the classification result and preset scene definition.
8. The apparatus of claim 7, wherein the electrical system comprises at least one of a power system, a braking system, a steering system, a thermal management system, a safety system, a regulatory system, a cockpit system, and a driving system.
9. An electronic device, comprising: memory, a processor and a computer program stored on the memory and executable on the processor, the processor executing the program to implement the power management method of a vehicle according to any one of claims 1 to 5.
10. A computer-readable storage medium on which a computer program is stored, characterized in that the program is executed by a processor for implementing a power management method of a vehicle according to any one of claims 1 to 5.
