Function test system and test method of automobile body control module

Abstract

The invention discloses a function test system of an automobile body control module. The function test system comprises a junction box which is connected with an automobile function module to be tested, and the junction box is connected with a digital board card which is connected with an industrial personal computer. The invention also discloses a test method by utilizing the system. According to the function test system and the test method, on the aspect of hardware construction, the realization is convenient and rapid, under the premise of ensuring the precision, the cost is lowered, the system is expanded by loading different functions of board cards, and then can be conveniently connected with a device to be tested by the junction box, and on the aspect of test software, the system has the largest characteristics that a state diagram is utilized for generating a test case, the test purpose is realized by traversing the work state of a BCM (Body Control Module), the understanding is convenient, the operation is easy, the test effect is achieved, and when the test case is tested, the automatic batch test can be selected, the singly manual test is conducted, the function consistency can be automatically analyzed and designed in advance, the manual comparison can be conducted to implement sequential analysis, so that the problem can be found and checked conveniently.

Description

technical field [0001] The invention relates to a function test system and a test method of a control module, in particular to a function test system and a test method of an automobile body control module. Background technique [0002] With the increasing application of electronic control units in automobiles, the data communication between electronic devices has become more and more. At the same time, the extensive use of these separate modules has not only improved the comfort of vehicles, but also brought about failure rates. Rise, complex wiring and other issues. As a powerful control module, BCM (BODY CONTROL MODEL) realizes the control of these discrete controllers, sensors and many electrical appliances. It includes various functional modules such as light control, wiper control, window control, and door lock control. It also has CAN and LIN gateway functions, which greatly improves the performance of the vehicle. There are more and more functions integrated by ...
