摘要
针对最坏响应时间法计算的保守性,分析了CAN网络报文传输的模型及影响网络性能的因素;从概率角度分析位填充机制,提出填充系数的概念。以典型汽车车身控制系统为例,利用填充系数法分析了帧时间以及负载率。
Because of the conservatism of the worst-case response time, the factors of the net and the model of the messages transmitting are analyzed; the bitstuffing framework is analyzed based on probability, and the concept of the stuffing coefficient is put forward. The time of frames and loading ratio are calculated with the stuffing coefficient algorithm based on the type automotive body controlling system.
