Vehicle body control module test system and test method

Abstract

The invention relates to a vehicle body control module test system and test method. The system comprises an industrial personal computer, a test adaptation unit, a signal router and a power supply module. Wherein the industrial personal computer is used for simulating a working condition signal; the test adaptation unit is used for simulating an external control signal and load information; the vehicle body control module is used for receiving working condition signals, external control signals and load information and outputting vehicle body control data; the industrial personal computer is also used for receiving the vehicle body control data and comparing the vehicle body control data with theoretical control data to obtain a test result; the signal router is used for providing network connection; the power supply module is used for supplying power. In the long-time endurance test process of the vehicle body control module, the system simulates each working condition of the vehicle body control module, measures the output control signal of the vehicle body control module and compares the output control signal with the theoretical value under the corresponding working condition, so that the function of the vehicle body control module is detected, and the test efficiency and the test accuracy of the vehicle body control module can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to a vehicle body control module testing system and a testing method. Background technique [0002] With the development of society, people are constantly improving the safety and comfort of vehicles, and the system components in the vehicle are also increasingly diversified and complicated. As the core control module in the body domain system, the body control module plays an important role in the safety, comfort and convenience of the car. Therefore, the reliability test of the body control module is an indispensable link in the development and verification process of the OEM's model. At present, many body control module manufacturers or test and testing institutions usually use the host computer software provided by the signal generator to perform manual operation tests during the environmental test process. For each test, it is necessary to convert the pairing learning...
