Problems solved by technology

However, there are two problems in this type of test method: (1) the test of the controller is limited to the test of electrical parameters, and some special function tests, such as CAN bus test and memory test, cannot be realized; (2) during the test process, The controller under test does not send test data according to the requirements of the test command, but sends all electrical interface information to the bus in real time, which will occupy CAN communication network resources, and the test status is uncontrollable

Abstract

The invention provides a method of carrying out an automatic test on an automobile electric control device. the method comprises the following steps: S1, test equipment sends a parameter test command to a tested electric control device according to the preset test sequence; S2, the tested electric control device receives the parameter test command and a test is carried out according to the parameter test command to generate test data; S3, the test data are sent to the test equipment; S4, the test equipment carries out a test on input parameters of the tested electric control device to generate reference test data; and S5, the test equipment generates a test report according to the test data and the reference test data. The method of carrying out the automatic test on the automobile electric control device adopts a request-response mode to realize comprehensive and high-efficiency test on the electric control device, both the electrical parameters and other functions can be tested, and the test state is controllable. The invention also provides equipment for carrying out the automatic test on the automobile electric control device.

Description

technical field [0001] The invention relates to the technical field of testing electric control products, in particular to a method for automatically testing an electric control device of an automobile and a device for automatically testing the electric control device of an automobile. Background technique [0002] With the wide application of electronic control technology in the whole vehicle, the intelligentization of automobiles is getting higher and higher, and the requirements for the safety and reliability of electronic control components are getting higher and higher. In order to ensure the safety of each electronic control component on the vehicle, it is required that the electronic control component must meet the safety and reliability requirements in the design stage, verification stage and production stage. [0003] At present, new energy electronic control components need to be strictly tested during the production stage. Therefore, in order to ensure that the fu...
