Abstract

The invention discloses a test system and method for a vehicle body central control unit. The test system of the vehicle body central control unit comprises a rack, a cabinet, and an upper computer; the rack is provided with a vehicle body central control unit to be test; the cabinet is connected with the rack; the cabinet is provided with a test board card; the test board card includes an input interface and an output interface; the upper computer stores a test program; the test program is executed in the upper computer, so that the upper computer transmits a test command to the input interface of the test board card; the cabinet sends test signals to the vehicle body central control unit through the output interface according to the test command so as to test the vehicle body central control unit and receives the test result of the vehicle body central control unit so as to generate a test report based on the test result. With the test system and method for the vehicle body central control unit of the invention adopted, the automatic test of the vehicle body central control unit can be realized, test efficiency can be improved, the repeated workload of personnel can be decreased,and test costs can be saved.

Description

Technical field [0001] The invention relates to the technical field of automobile production, in particular to a test system and method for a vehicle body central control unit. Background technique [0002] With the continuous development of automotive electronic technology, the number of various electronic control units ECUs in automobiles continues to increase. These electronic control unit ECUs usually require a central body control unit (CBCU: Center Body Control Unit) for unified control. Therefore, the stability and reliability of the vehicle body central control unit has a vital impact on vehicle safety and performance. [0003] Once the control logic of the central control unit of the vehicle body is unreasonable or has defects, it will seriously affect the safety and performance of the vehicle. Therefore, it is necessary to test the control logic of the vehicle body central control unit. In related technologies, testers usually perform tests manually, and testers perform...
