Real-time analysis of dynamic priority of CAN bus protocol

Based on the static scheduling algorithm, the article, which introduced a dynamic priority promotion mechanism for CAN, proposed a scheduling algorithm with the advantages of both static scheduling algorithm and dynamic scheduling algorithm. The algorithm can improve the real-time transmission of data; especially data with low priority and the utilization rate of CAN network bandwidth being very high. The simulating results show that the transmission of data with different priorities can be remarkably improved, which verify the design concept.
