In this paper, by using the advantages of Adams/CAR software, the simulation model of automobile dynamics is built; based on linear quadratic of optimal control theory and direct yaw moment control （DYC） theory, the feed forward-back composite control system software and the joint control module with ADAMS are built in Matlab. Co-simulation between ADAMS and MATLAB is realized to control the stability of vehicle. By adjusting the control system parameters, the step condition simulation on slippery road surface is done, the results of the co-simulation are analyzed, the best effect of the controller on the vehicle＇s stability control is achieved. The results showed that the designed control system can improve vehicle stability effectively.
