Vehicle stability control system simulation

Vehicle handling and stability control is based on road conditions and vehicle movement state control of the movement of vehicles to prevent vehicle handling and control, and thus more effective to improve vehicle stability and driving safety, it belongs to the field of automotive active safety research, is the current hot topic. In this paper, the control of vehicle handling and stability at home and abroad studies present situation, the use of fuzzy control theory to vehicle handling and stability were studied. First in the ADAMS / CAR vehicle virtual prototype model to establish and verify the correctness of the model by testing for the control system to provide a reasonable model. Vehicle dynamics stability under the basic principle of the system, a single wheel brake to generate additional yaw moment to improve the cars handling and stability under extreme conditions. Control system for vehicle handling and stability of nonlinear, time-varying characteristics, the choice of robust, practical, easy operation of the fuzzy control method, designed yaw rate feedback controller and sideslip angle feedback fuzzycontroller, and the yaw rate and sideslip angle feedback control of the joint fuzzy controller, and finally through the ADAMS / CAR and MATLAB / Simulink co-simulation of these three controllers. Simulation results show that: the three controllers are to achieve a better vehicle stability control, which yaw rate and sideslip angle feedback fuzzy controller to control the joint is superior to exercise control of a single variable fuzzy controller The results of automotive electronic stability control system hardware development has certain reference significance.
