Vehicle dynamics control based on sliding mode control technology

The paper presents a vehicle dynamics control strategy devoted to prevent vehicles from spinning and drifting out. With vehicle dynamics control system, counter braking are applied at individual wheels as needed to generate an additional yaw moment until steering control and vehicle stability were regained. A sliding mode controller was designed to produce demanded yaw moment according to the error between the measured yaw rate and desired yaw rate. Vehicle dynamics control system utilizes the demanded yaw moment to calculate the brake torque on wheels respectively. With this improved control system, the vehicle can afford nice manoeuvrability and stability.
