Abstract

The invention discloses a vehicle electrical accessory control system, a control circuit and a vehicle. The system comprises at least one electrical accessory, wherein the at least one electrical accessory comprises at least one of the following: a power-assisted steering oil pump motor, an air compressor air pump motor and a battery; an overall controller connected to each electrical accessory for controlling the conversion of a direct current provided by a power battery on an electric vehicle into a corresponding working current of each electrical accessory, wherein the working current comprises at least one of the following: a first working current for the power-assisted steering oil pump motor, a second working current for the air compressor air pump motor, and a third working currentfor the battery. The invention solves the technical problems of a large number of circuits and interfaces of the electric vehicle due to that each electric vehicle accessory adopts a separate controller for control in the existing electric vehicle accessory system.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a control system, a control circuit and a vehicle for electric accessories of a vehicle. Background technique [0002] With the increasingly prominent problems of environmental pollution and oil energy shortage, pure electric vehicles with the characteristics of zero pollution and low energy consumption are developing rapidly.
