汽车CAN FD总线报文周期一致性的测试方法及应用

Testing Method and Application of Message Cycle Consistencyin Automotive CAN FD Bus

随着汽车智能网联技术的不断发展,汽车功能需求开发对总线数据传输质量和稳定性要求也越来越高,汽车总线网络开发设计过程中,需要考虑总线的负载率对实际网络稳定性的影响。总线数据传输稳定是功能应用开发的可靠保证,因此,针对总线负载高引起的报文丢帧或延迟问题提出一种自动测试报文周期一致性方法,这种自动测试报文周期一致性测试方法对网络总线开发设计具有重要意义。

With the continuous development of automobile intelligent networking technology,the development of automobile functional requirement requires higher and higher bus data transmission quality and stability.During the development and design of automobile bus network,the impact of bus load rate on actual network stability needs to be considered.The stable transmission of bus data is a reliable guarantee for functional application development.Therefore,an automatic testing method for message cycle consistency is proposed to address the issue of message frame loss or delay caused by high bus load.This automatic testing method for message cycle consistency is of great significance for network bus development and design.
