提出了车辆动力学稳定性控制的控制目标,基于滑模变结构控制理论,并综合考虑主动制动车轮的滑移率对车辆稳定性的影响,设计了车辆动力学稳定性控制器;基于ADAMS/Car和MATLAB/Simulink联合仿真平台,分别采用阶跃转向工况和单移线工况进行了联合仿真,验证了该控制器的正确性。研究成果为实际车辆动力学稳定性控制系统设计提供了理论依据。
This paper put forward the target of vehicle dynamics stability control, designed the controller based on variable structure control and the infection from the variety of slip rate. In step steering and single lane changing environment, the validity of this strategy was proved by means of co-simulation between ADAMS/Car and Matlab/Simulink. The vehicle stability and maneuverability in critical situation are enhanced, which has provided a foundation of theory to design of vehicle dynamics stability control.
