Recently multilayer automotive nets systems based on CAN and LIN are adopted to solve problems of the increasing of wire bunch weight, lack in module installation space in automotive electronic systems and so on. The software structure of multilayer automotive nets becomes more and more complex, and the real-time of control messages on the automotive nets is difficult to describe. The difficulty of designing multilayer automotive nets software is discussed and a modeling method for hierarchical automotive nets based on the object-oriented Petri net is proposed in this paper. First the model describes each subsystem behavior of real-time processing messages and controlling implemental devices, and analyzes features of information sharing among the objects, and then the paper puts forward a software framework for automotive body control subsystem. Second, the model is used to analyze features of information sharing among the objects. Third, it is used to describe each subsystem real-time behaviors of processing messages and implemental device controllers operating, and put forward a reasonable software framework for the automotive body control subsystem. This study can help to design and analyze the object-oriented model in the automotive body system effectively, and provide a convenient and rapid way for developing the logical multilayer automotive nets systems software.
