Anti-electromagnetic interference control method and motor controller integrated assembly for electric vehicle

Abstract

The invention discloses an anti-electromagnetic interference control method and a motor controller integrated assembly for an electric vehicle. A controller used for achieving driving control over a motor is installed on the end face of a stator assembly of the motor. In the starting operation process of the motor, the controller at least adopts one of the following steps to carry out anti-electromagnetic interference control: A10) pre-checking characteristic parameters of the motor by utilizing a checking handshake protocol, B10) removing superposed interference signals from the sampled current signals through a filtering algorithm, C10), removing the superposed temperature ripple signals through a temperature algorithm, and D10), removing signals with Hall duty ratios not in a preset range through a position sensing algorithm. The problem of electromagnetic interference after the motor and the controller of the electric vehicle are integrally installed can be effectively solved, and the normal driving performance of the motor controller integrated assembly is ensured.
