According to the ideal vehicle model with twodegrees of freedom of the transverse effect of yaw rate and sideslip angle ofthe vehicle stability, the yaw rate and side slip angle as the controlparameter of vehicle stability control system, through the PID controlalgorithm and the Genetic Optimization PID control algorithm is studied on thesimulation diagram, andbuilding in matlab/simulink, theauthor makes a comparison an,d simulation analysis results of the twoalgorithms. Through the combination of simulation results, Genetic OptimizationPID control algorithm has better control effect than PID control algorithm. The amplitude of the yaw rate and sideslip angle andthe overshoot is significantly reduced, significantly improving the stability of automobile when steering.
