Simulation Study of Vehicle Brake Stability Control on Turning Lane Based on ABS

Abstract:

Vehicle under braking in turn condition can easily cause lateral instability because of the centrifugal force. In this paper, the defects of ABS control methods of the vehicle under braking in turn condition were analyzed, a braking force control strategy by the integrated control of ABS and yaw moment control for vehicle cornering is presented. Based on ABS, a yaw moment controller using fuzzy control theory is designed, by controlling yaw moment of vehicle and regulating slip rate of wheels, the dynamic regulation of yaw moment in vehicle braking is realized, therefore, vehicle braking stability on turning lane is improved. A simulation is performed with it during two different conditions: step input and sinusoidal input, the results showed that the transient and steady response based on presented method is better than that of ABS only, and the presented method can effectively control the yaw rate and side slip angle synchronously, achieve good transient and steady response, lighten the burden of the driver and improve vehicle yaw stability.
