Cyber Physical System( CPS) ,as a new topic in research of computer science and technology,is the fusion of computation,communication and control. The Auto Adaptive Cruise Control ( ACC ) system is thought as a typical CPS,which has wide application prospect. This paper builds the mathematical model for the vertical travel of the car,and gives the architecture and the system state machine model of the ACC based on the theory of CPS. It designs the model of vehicle ahead,own vehicle and the distance between the two vehicles based on Ptolemy,and builds the hierarchical model of the system. In the submodel of the system, it constructs the system behavior model which is combined with model based on time and state model with the modal model. Simulation results show that the method can meet the requirements and ensures the security of ACC system.
