A method and device for automatic testing of electronic control devices of automobiles

Abstract

The present invention proposes a method for automatically testing the electronic control device of an automobile, which includes the following steps: S1, the test equipment sends a parameter test command to the electronic control device to be tested according to a preset test sequence; S2, the electronic control device to be tested The device receives a parameter test command, and performs a test according to the parameter test command to generate test data; S3, sends the test data to the test equipment; S4, the test equipment tests the input parameters of the electronic control device under test to generate benchmark test data; S5, the test device generates a test report according to the test data and the benchmark test data. The method for automatically testing the electronic control device of the automobile adopts a request-response method to realize comprehensive and efficient testing of the electronic control device, not only can realize electrical parameter testing, but also can realize other functional tests, and the test state is controllable. The invention also proposes a device for automatically testing the electric control device of the automobile.

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...

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
