Abstract

Abstract:

The handling stability control of vehicles plays a vital role in their active safety.This paper deals with the handling stability control of the electric vehicle based on the anti- directional Bi- rotary motor.First,a model of the vehicle in an ideal status is established to estimate the yaw rate and the side- slip angle,and the phase plane method is used to design the stability criteria of the vehicle,so as to detect the driving situation.Next,a fuzzy yaw moment controller is employed to estimate the compensatory yaw moment according to the instability situation of the vehicle.Then,the slip rate of the target wheel is estimated by using a slip rate controller and is adjusted to a re-quired value by means of the PID control,the fuzzy control,and the fuzzy PID control of both the brake system and the anti- directional Bi- rotary motor.Finally,the vehicle is analyzed by using the simulation software Vedyna.The effectiveness of the proposed control strategy is thus verified.

Key words: vehicle stability control system, anti- directional Bi- rotary motor, yaw rate, side- slip angle, fuzzy control
