Abstract

The invention provides an automobile low-voltage power supply control system and method. The automobile low-voltage power supply control system comprises a battery, a central calculation module and a plurality of regional power supply controllers, the battery is connected with the central calculation module and the regional power supply controller, and the regional power supply device is in communication connection with the central calculation module; the area power supply controller is connected with a user-defined electric device and a basic electric device in the area, and the basic electric device and the user-defined electric device are respectively in communication connection with the central calculation module. The method comprises the following steps of S1, receiving a signal, and judging whether to switch a power supply mode or not according to the signal; if yes, switching a power supply mode; S2, after the power supply mode is switched, the user-defined electric device being switched on or off according to setting of the user-defined electric device in the power supply mode; and S3, receiving a signal, and judging whether the user-defined electric device is reset or not; and if yes, updating the on or off information of the user-defined electric device in different power supply modes. According to the method, personalized function requirements of users can be met, and electric energy loss is saved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile low-voltage power supply control method and system. Background technique [0002] The power output system of low-voltage power supply for automobiles is mainly composed of low-voltage batteries, low-voltage power generation system or low-voltage conversion system, ECU (Electronic Control Unit) with low-voltage power supply output, fuses, relays, wiring harnesses, etc. For traditional fuel vehicles, the low-voltage power generation system uses the engine to drive the generator to generate low-voltage power generation; for pure electric vehicles, the low-voltage conversion system uses DCDC to convert the high voltage of the power battery into a low-voltage power supply. The electrical load of the low-voltage power supply of the automobile includes all the low-voltage electrical appliances of the automobile, which are mainly composed of three types of electrical appliances: ...
