2014中国汽车工程学会年会用户论文集：The development of the vehicle network always involves numerous tests requiring lots of manpower and material resources on traditional methods. This automated test system applicable to the automotive electronics field is relatively more convenient and efficient. This system, includes a power supply module, a digital signal I/ O module, a signal disturbance source, a real vehicle network bench and a man-machine software, can test CAN network management protocol and measure physic and data link layer property of CAN signal. Trough automatically generated reports from man-machine software, users in vehicle companies can verify ECU providers’quality and analysis the controllers'performance in CAN network.CAN网络在汽车ECU中的一个自动测试系统
