Cyber-physical system is a kind of hybrid system that connects the information system and the physical system. It includes various technologies such as sensing, communication, computing and control. Its system operation includes both discrete computing process and continuous physical process. Aiming at this characteristic, an event-driven and data-centric augmented hybrid Petri net model is proposed. Firstly, CPS has an event-driven intrinsic attribute, defines a variable factor for assigning data value to events, and takes data as the core of the execution level of the event. Secondly, temporal and spatial attributes are added to the hybrid Petri nets, and the concept of conditional arcs is introduced for the occurrence of transitions. Finally, the operational mechanism of the adaptive cruise control system is modeled and analyzed to verify the feasibility of the proposed model.
