Stability control of electric vehicles based on a novel longitudinal force distribution strategy and Smith predictor
نویسندگان
چکیده
In this paper, a novel yaw moment control system is proposed to improve vehicle’s handling and stability. The control system includes reference model, DYC controller, Distributer, and Smith predictor. The reference model is used to obtain the desired yaw rate. The DYC controller determines the desired yaw moment by means of sliding-mode technique. The Distributer, based on maneuverability and comfort, distributes driving torque or braking torque according to the desired yaw rate. The Smith predictor based on linear vehicle model is used to solve the time delay problems caused by actuators and sensors/observers. The simulation results show that the proposed control algorithm can improve vehicle’s handling and stability effectively. Key-Words: Electric vehicles; Drive force distribution; Longitudinal force distribution; Sliding mode Control; DYC
