Timing Parameter Choosing and Application in Diagnostic Design of A Heavy Truck

文章以某型重卡的诊断定时参数设置为例,浅述了UDSonCAN协议中关于诊断定时参数的相关要求及具体应用流程,将诊断协议中定时参数的使用场景具象化,选择合适的定时参数数值,通过控制器诊断测试流程进行校验分析,既可以满足控制器诊断测试的可靠性要求,也提高了诊断流程的效率,为相关车型的诊断测试提供一定的参考。

In this paper, a heavy truck is taken as an example to describe the vehicle diagnostic timing parameters setting, and introduces the requirements on the diagnosis of timing parameters in the UDSonCAN protocol and the specific application process.Visualize of the use of the timing parameters in the diagnostic protocol. By choosing the appropriate timing parameters, the controller diagnostic test flow is used for verification and analysis. It can not only meet the reliability requirements of the controller diagnostic test, but also improve the efficiency of the diagnosis process, and provide a reference for the diagnosis and testing of the related vehicle type.
