Abstract

The invention relates to an automotive four-motor controller and a control system. The controller comprises a master control unit, a bus voltage detection unit, a drive signal output unit, a position signal processing unit, a current signal processing unit, a temperature signal processing unit and a bus unit, wherein the master control unit is used for generating four paths of drive signals; the bus voltage detection unit is used for collecting direct current bus voltage; the drive signal output unit is used for outputting the four paths of drive signals; the position signal processing unit is used for collecting rotating speed and position signals of four motors; the current signal processing unit is used for collecting current signals of the direct current bus and the four motors; the temperature signal processing unit is used for collecting cooling water temperature of the motors and the controller; the bus unit is used for connecting the master control unit and an automobile control unit; and the master control unit is in two-way connection with the bus voltage detection unit, the drive signal output unit, the position signal processing unit, the current signal processing unit, the temperature signal processing unit and the bus unit respectively. According to the automotive four-motor controller, the number of the motor controllers can be reduced; and the wire harness arrangement is optimized, so that the reliability of an electric automobile control system is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle control, in particular to a vehicle four-motor controller and a control system. Background technique [0002] With the development of wheel motor technology and hub motor technology, the automobile industry is developing from traditional internal combustion engines to electric vehicles powered by electric motors.
