摘要
为了保障车载网络的畅通和LIN网络应用层设计的正确性,需要在开发阶段对应用层协议进行测试。在分析了LIN网络各种性能指标的基础上,开发了LIN总线测试系统;在测试车身网络时,着重研究了LIN总线应用层中调度表设计对总线性能的影响。测试结果表明,LIN调度表的设计对车载网络性能的优化有着极其重要的作用,这为LIN总线应用层协议设计提供了依据。该测试系统已在某车型车身网络开发过程中得到了应用,并取得了良好的效果。
To ensure in-vehicle network to be unblocked and the correct design of local interconnect network(LIN) application layer,it is necessary to do the test in developing stage for the protocol of application layer.On the basis of analyzing various performance indexes of LIN,the test system of LIN bus is developed.In testing auto body network,the influence of the design of scheduling tables in application layer of LIN on bus performance is researched emphatically.The test result indicates that the design of scheduling tables greatly affecting on optimization of performance of the auto body network,it provides foundation of design on application layer protocol of LIN bus.This test system has been applied in the developing process of certain auto body network,and has a good results.
