Abstract

The invention provides an automatic tester and an automatic method for a vehicle controller. The automatic tester for the vehicle controller is connected with the vehicle controller to test the vehicle controller, and comprises a signal collection unit, a signal generation unit, a control unit and a parameter configuration unit. The signal generation unit is used for generating test signals underthe control of the control unit and sending the test signals to the vehicle controller to do tests. The signal collection unit is used for collecting output signals, which are output by the vehicle controller to respond the test signals, and sending the output signals to the control unit. The control unit is used for judging whether the vehicle controller has operation faults or not according to the collected output signals. The automatic tester for the vehicle controller has the advantages that automatic testing can be realized, comprehensive and accurate testing is guaranteed, testing efficiency is improved greatly, testing reliability is improved, artificial influences are avoided, labor operation is reduced, testing content and parameters can be adjusted, and support is provided to production line visualization.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to an automatic testing device and method for a vehicle controller. Background technique [0002] For the traditional test of the vehicle controller, it is still at the level of manual testing. The traditional test instrument uses a single-chip microcomputer as the control circuit, LEDs as the indicator light, and various buttons as the switch input form. The various functions of the control module are tested step by step manually, the test efficiency is low, the reliability is poor, and the product is difficult to trace. The common problem is that the testing process is cumbersome and some characteristics are difficult to detect; the amount of data is large, and manual processing is difficult; the efficiency of manual testing is low, and the risk of human factors is relatively high. Contents of the invention [0003] In view of this, the purpose of the embodiment ...
