摘　　要：采用确定与随机petri网(DSPN)对CAN总线通信过程进行建模仿真,通过改变系统参数:信息到达时间间隔,受阻率和通道忙闲率,分析该系数对系统性能参数,即吞吐量和冲突概率的影响,从而有效地分析CAN总线系统的实时性能,为实际工程应用提供有价值的理论与方法。Deterministic and Stochastic Petri Net （DSPN） is adopted in modeling and simulation of CAN communication process. By changing the system parameters, such as interval of information arrival, blocked rate, access busy and idle rate, while analyzing effects of those parameters to system performance parameters--throughput and collision rate, the real-time performance of CAN is effectively analyzed, and valuable theories and methods for practical applications are provided.
