Abstract:

The car's BCM plays a pivotal role in the body function control system.Therefore,both the enterprise and the consumer attach great importance to the detection of car's BCM before they leave the factory.Most of current enterprises still use manual testing methods.This test system uses samsung's S3C2440 as the core controller,uses the Qtopia application development platform control interface under the embedded Linux system to add a testing and control program,and realizes automatic detection through the interface board which connects car's BCM.

Key words: car BCM;ARM Linux;Qtopia;automatic detection
