      Abstract:Based on the automobile with cruise control system, the paper analyzes the structure and functions of cruise control system, through the analysis of the principle of PID controller, a controller algorithm for cruise control system are established, and the key parameters of the controller are confirmed later. After calibration and real road test on vehicle, the results show that the system has better control accuracy and fast response speed, works stably and can satisfy the actual use needs of automobile cruise control system.
