Automated test system design based on Tellus for in-vehicle CAN network

Aiming at the requirements of high efficiency, high reliability in testing electrical modules of in-vehicle network, Based on CAN network environment of passenger-cars in Beijing Automotive Technology Co., Ltd.(BATC), by means of IPC-610L, vehicle protocol tester Tellus™ Pro(Tellus), CAN bus interference generator CAN Spider, programmable power supply, self-made relays module, Digital I/O cards, diagnostic testing tool Electrical Tester System(ETS), and by programming with Tellus software and other upper computer software on the platform of LabVIEW, an automated test system used for CAN network nodes in vehicles is designed. It can be used for various ECU network tests, diagnostic tests from different car models. After conducting a series of network node test on the system, the validity of this test system is then verified.
