总线自动化测试设备的设计与研究

Design and Research of Bus Automatic Test Equipment

由于现代汽车电子技术的迅速发展,电子控制器在汽车上的应用越来越多,各控制器之间的信息交互日益复杂,总线技术在车辆上的应用逐渐普及,相应的CAN总线测试技术也不断发展。搭建基于NI硬件的总线自动化测试设备,自动运行测试设备中的测试用例,实现对相应总线控制器的自动化测试,减少测试时间,提高测试效率。

With the rapid development of modem vehicle electronic technology, more and more ECUs are applied in vehicles. The information interactions between control units are increasingly complex. The CAN bus technology on vehicle is gradually gaining ground, and the corresponding CAN bus testing technology is also developing continuously. By setting up a NI-hardware-based CAN bus automatic testing device to execute the inside test cases automatically and accomplish the automatic tests of corresponding CAN bus control units, it can save testing time and enhance efficiency.
