Abstract:

    We design a universal hardwareintheloop test system for a vehicle body control module (BCM) to verify the validity and reliability of its software. It includes test software, data acquisition and periphery circuit and has such functionalities as data acquisition, status display, analogous control and online testing. We explain the test process by an individual functionality test based on the analysis of test requirement. A BCM product is tested with the system.Test result indicates that the system can satisfy the reality requirements, and can improve work efficiency. It therefore can be applied to other application scenarios with similar requirements.

Key words: vehicle body control module, hardwareintheloop testing, virtual instrument
