Aiming at the problem of lateral control in driverless vehicle, this paper proposes the application of intelligent PID control algorithm to driverless vehicle. Intelligent PID control is a new type of intelligent model free control method, which combines traditional PID control and intelligent control technology. It has good robustness, self-learning, self-adaptive and other excellent characteristics. In this paper, the kinematical model of driverless vehicle is established, and the lateral control problem is mainly studied. On this basis, the intelligent PID controller is designed, and the control algorithm is simulated and verified in MATLAB. The experimental results show that the intelligent PID control algorithm can well solve the highly nonlinear problem of the lateral control in the driverless vehicle, and can meet the requirements of driving.
