基于网关互连的CAN网络最坏响应时间分析
Worst-case response time analysis for messages in Controller Area Network(CAN)based on gateway-interconnection
摘要
Abstract
Controller Area Network(CAN)is widely used in automotive electronics systems. It needs a gateway for com-munication between different CAN networks. For existing exhaustive search algorithm and simplify search algorithm, they both ignore the impact of higher priority message in the analysis of non-period inference caused by gateway message. This paper considers this point and improves the Worst-Case Response Time(WCRT)analysis for messages in CAN based on gateway-interconnection by considering the ignored higher priority messages and proving that gateway messages can cause maximum non-period interference when being released simultaneously. Finally simulation experiment is used by Matlab, and the experiment results indicate that the improved algorithm has lower time complexity and can reduce pessimism of the results.关键词
