中文摘要：
信息物理融合系统（ CPS）是计算、通信与控制技术的融合,汽车自适应巡航控制系统是一种典型的CPS,具有广泛的应用前景。通过建立汽车纵向行驶的数学模型,并基于CPS给出自适应巡航控制系统的结构,设计系统的状态机模型。基于Ptolemy分别设计前车、测量距离和本车的计算模型,构建系统的层次模型,在子模型中采用模态模式对基于时间的模型与状态机模型相结合的混合系统行为进行建模。仿真结果表明,该方法能满足自适应巡航控制系统的要求,保证系统的安全性。
英文摘要：
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.
