车载总线自动化测试系统的设计与应用

随着现代汽车技术的迅速发展,当汽车网络上电控单元数量越来越多,总线结构越来越复杂时,测试工作量将成倍增长,传统手动测试已无法满足测试需求。通过对车载网络总线测试的研究,分析了测试方法的优缺点,提出了一种车载网络自动化测试系统。该系统以Vector的工具链为测试平台,通过C#语言开发的上位操作平台对系统进行配置与控制以完成车载网络CAN(controller area network)总线、CANFD(CAN with flexible date-rate)总线、LIN(local interconnect network)总线的测试,解决了以往测试过程中通用性差的缺点,提高了测试效率。

Design and Application of The Vehicle Network Automation Test System

With the rapid development of modern automotive technology, When the number of electronic control units on the car network is growing and the structure of the bus is more and more complicated, the workload will grow exponentially and the traditional manual test has been unable to meet the test requirements. By testing the vehicle network bus research and analyzing the advantages and disadvantages of the test method, this paper presents a vehicle network automation test system,which takes the tool chain of Vector as the testing platform and configures and controls the system through the upper-level operating platform developed by C # to complete the test of the on-board network CAN bus, CANFD bus, and LIN bus, this method improves the test efficiency and solves the shortcomings of poor versatility in the past testing process
