摘　　要：搭建了基于Matlab/Simulink/Stateflow的15自由度汽车动力学稳定性控制仿真平台,通过实车实验验证了仿真平台的精确性。应用该平台和β法分析了主动制动横摆力偶矩对汽车动力学稳定性控制(DSC)的作用,研究了基于车身姿态控制和轮胎滑移率控制的DSC主副循环控制算法。通过软、硬件在环仿真与实车实验验证了动力学稳定性控制的效果,为汽车动力学稳定控制系统的研发提供了有效的平台。The simulation platform for the vehicle dynamics stability control was studied based on the 15 DOF vehicle dynamics simulation model with Matlab/Simulink/Stateflow. The accuracy of the simulation system was tested by the real vehicle experiment. Applying the platform and the β method, the stability control effect of the yaw moment from the active brake to DSC was analyzed, then control arithmetic for the DSC with the outer control loop for the vehicle attitude and the inner control loop for the tire slip rate control were studied. The control effect was tested through the software-in-the-loop simulation and vehicle experiment. Then the available platform for the DSC research was established.
