Abstract: Cyber physical system (CPS) is composed of networked physical devices,in which computing entities are embedded to perceive everything and controll the running of the devices.Evaluating the integral effect of the physical and computing arguments,control indicators and related real-time properties is essential to the product development of a CPS system.In this paper,an intelligent vehicle was taken as the research object,and an extended differential Petri net (DPN) model was adopted to establish the integrated model of its cyber physical behavior and desired control effect,in which the key design elements are reflected.By executing of the model,the integrated control effect is judged directly from the model.This method provides an effective way to assess the integral properness,and combined design of key design indicators of a CPS system.
