Whole vehicle function test system and method

Abstract

The embodiment of the invention provides a whole vehicle function test system and method. The computer equipment sends a test instruction to the calibration tool, wherein the test instruction comprises a test case; in response to the test instruction, the calibration tool calibrates the fault of the tested controller corresponding to the current test case to generate a fault mark; the calibration tool sends a fault mark to the gateway controller and the computer equipment; the gateway controller sends a fault instruction to the tested controller according to the fault mark; the tested controller breaks down according to the fault instruction; the computer equipment inquires a first processing strategy corresponding to the fault mark; If the computer equipment judges that the first processing strategy is the same as the set second processing strategy, the computer equipment collects a first controller local area network signal value so as to test the whole vehicle according to the first controller local area network signal value.

Description

【Technical field】 [0001] The invention relates to the technical field of vehicles, in particular to a vehicle function testing system and method. 【Background technique】 [0002] According to the automobile "V" model development process stipulated in the ISO26262 standard, the whole vehicle needs to undergo a system integration test, that is, a vehicle function test, to verify whether the system function meets the design requirements. Conventional functional tests can only collect vehicle Controller Area Network (CAN) signals for observation. For tests with high test timing requirements, normal signal-level functional tests cannot be satisfied. In related technologies, the vehicle function test is limited by many conditions, and some fault tests need to destroy the vehicle under test to conduct the vehicle test, which makes the operation of the actual test difficult, the test takes a long time, and reduces the test efficiency of the vehicle. 【Content of invention】 [0003]...
