Abstract

The invention provides an automatic diagnostic test system based on a vehicle body domain controller. The automatic diagnostic test system comprises a test host, a test board card, a network monitoring device, a power supply device, a resistance matching circuit board, a real load and a tested controller. The test board card includes a control board card, an analog board card, a load board card, aconditioning board card, a power distribution board card and a fault injection board card. The automatic diagnostic test system can automatically diagnose a function of the tested controller, can automatically diagnose an ECU in a simulated ECU environment, does not depend on a real ECU environment, and can automatically execute test cases and the result judgment, thereby avoiding the error of the manual testing and improving test efficiency and accuracy.

Description

technical field [0001] The invention relates to the technical field of vehicle controller bus diagnostic testing, in particular to an automatic diagnostic testing system based on a vehicle body domain controller. Background technique [0002] With the rapid development of automotive electronics technology, the functions of on-board controllers are becoming more and more complex, among which the diagnostic function is essential. Most of the diagnostic functions of existing on-board controllers are implemented based on CAN bus diagnostic specifications, such as diagnostic-related international standards ISO15765 and ISO14229, etc. Some of the diagnostic functions are custom-developed by various OEMs. Through the diagnostic function, it is possible to read and clear the fault code, configure the offline configuration of the production line, the dialogue service of the diagnostic instrument, and the program flashing function, etc. Therefore, the diagnostic test verification of t...
