Modeling and Simulation of Yaw Controlling for Vehicle Stability Control System

The vehicle reference model,and a 8-DOFs vehicle dynamics model covering yaw and roll motion are established in Matlab/Simulink.Using the method of different states of yaw angle,a direct yaw control strategy has been proposed based on fuzzy control principle,then the stability control of the vehicle ESC system is achieved.The results of fishhook test simulations in characteristic cycles show that the designed control strategy can effectively implement yaw stability control and reduces lateral acceleration.Furthermore,the vehicle's anti-rollover capacity is increased,and the stability and safety of the vehicle are enhanced.
