CONTROL METHOD FOR IDLE ANTI-ROLLBACK OF PURE ELECTRIC VEHICLE

摘要

Disclosed is a control method for idle anti-rollback of a pure electric vehicle, and the steps are as follows: a vehicle controller determines whether anti-rollback control of the vehicle is required in the current status according to a brake pedal, a handbrake device, and an accelerator pedal; if required, a determination is made to judge whether the current status of a power battery, a motor controller, and the motor satisfy the working conditions of the anti-rollback control; if not satisfied, the torque output of the motor is stopped; if satisfied, the motor outputs the torque for the anti-rollback control. The method applies to an idle starting of the pure electric vehicle, and effectively prevents the rollback of the electric vehicle on a slope. The method has a simple and quick processing procedure, with a stable and reliable performance, thereby being able to be applied in a wide range.
