Problems solved by technology

At present, many domestic manufacturers have been able to independently design automotive body controllers, but their product testing is still at the level of manual testing, with low efficiency, poor precision, large errors, and long testing cycles.
At the same time, with the increase of body controller functions and signals, the workload of test engineers is also increasing exponentially

Abstract

The invention relates to a network communication signal automatic testing system for a body control module (BCM). The system is characterized in that a testing industrial personal computer is connected with a touch display screen through a VGA line to display a test case, a test process and a test result. A USB interface is connected with and controls an automobile network interface card (VN8910). The automobile network interface card (VN8910) is connected with and controls a board backplane (VT8012) through an Ethernet interface. The board backplane returns the test result to the automobile network interface card, and ultimately the test result is returned to the testing industrial personal computer to form test data and a test report. The network communication signal automatic testing system can accurately and efficiently test all the functional signals of the BCM.

Description

technical field [0001] The invention relates to an automatic test system for network communication signals of a vehicle body controller (BCM), which is an automatic test system for efficiently completing the function signals of the vehicle body controller. Background technique [0002] On today's motor vehicles, electronic control units are increasingly used in modern cars. The body controller is one of the important automotive electronic controller devices, including central door lock control, electric window control, light control, wiper control, etc. At this stage, many domestic manufacturers have been able to independently design automobile body controllers, but the testing of their products is still at the level of manual testing, with low efficiency, poor precision, large errors, and long testing cycles. At the same time, with the increase of body controller functions and signals, the workload of test engineers is also increasing exponentially. Contents of the inven...
