| 摘 要： | 过去对CAN的漏检错帧概率的研究很有限,数据的获得主要依靠大量的仿真测试.由于要仿真的量太大,实际上仿真的仍然是极小的样本,所以得到的漏检错帧概率可信性不足.本文介绍了漏检实例的构造方法,从而进行漏检错帧概率下限的分析计算.得到的CAN协议的漏检错帧概率远大于以前的结论,因此对CAN的应用有巨大的冲击.由于已有大量应用...

| Abstract: | Limited literatures were published about the research of undetected frame error rate of CAN protocol.They were based on the software fault injection.Though the simulation was exhausting,but in comparing with the possible quantity of error cases it was a very small sampling.Hence the conclusion based on that simulation is less persuasive.Present paper gives a reconstruct method of error undetected frame.Based on this method the lower boundary of undetected error rate obtained is several orders higher than th... |
