Coordinated Vehicle Lateral Stability Control Based on Direct Yaw Moment and Engine Torque Regulation under Complicated Road Conditions

This paper proposed a control method of vehicle lateral stability system. In order to obtain the best driving performance under complicated friction conditions track, direct yaw moment (DYC) and engine torque regulation (ETC) value need be adjusted avoid penalisation each other. Firstly, intervention timing is studied, which judged by phase plane longitudinal speed threshold method, respectively. Then, algorithm based on sliding mode designed, its target calculation depends linear two-degree-of-freedom model. The calculated fuzzy algorithm. input values are mainly state parameters driver’s steering wheel. Matlab/Simulink, AMESim, CarSim software programs used simulate sine with dwell maneuver. simulation results show effectiveness cooperation in this paper.
