According to the survey,20%fatal traffic accidents are caused by fatigue driving.Adaptive cruise control(ACC)sys-tem plays an important role in reducing fatigue driving.In the study of Adaptive Cruise Control,the core control algorithm is a major re-search direction.At present,Proportion Integral Differential(PID)is widely used in ACC.However,the PID has some drawbacks,such as overshoot and oscillation,which cause the poor tracking performance.In this paper,the simulation model of ACC is constructed by Matlab,then the optimal control algorithm is applied to ACC which basic application flow and the choices of paremeters are dis-cussed,Finally the tracking performance based on optomal control is compared to PID by comparing the residual sums of squares.The following conclusion can be drawn from the study,optimal control has better tracking performance than PID.
