Vehicle control unit test system and vehicle control unit test method

Abstract

The invention provides a vehicle control unit test system and vehicle control unit test method. The test system comprises a test table, a vehicle control unit and an upper computer; the vehicle control unit collects message information and analog information of an analog controller in the test table; the vehicle control unit generates a first control instruction according to the message information and the analog information and sends to the analog controller; the upper computer acquires the analog information and the first control instruction and tests whether the vehicle control unit runs normally or not according to the analog information and the first control instruction. By the arrangement, full-functional test of the vehicle control unit can be achieved, qualitative and quantitative verification on system integration level is realized, and test results are more accurate.

Description

technical field [0001] The present invention relates to vehicle testing technology, in particular to a testing system and method for a vehicle controller. Background technique [0002] Compared with traditional cars, the control method adopted by pure electric vehicles is that low-voltage electricity controls high-voltage electricity. The controllers in pure electric vehicles mainly include vehicle controller (VCU), motor controller (MCU), and battery management system (BMS). Among them, the VCU plays a coordinating and overall planning role and position in the entire system. The performance of the VCU function is related to the safety of the vehicle and driving in line with the driving intention. Therefore, it is very important for the test verification of VCU. However, the current system integration test of VCU relies more on the real vehicle test. Many problems can be found in the real vehicle test, but the real vehicle test has great limitations, and it is difficult t...
