How are automotive parts tested?

1.? Bench building:

This link is mainly to connect the controllers according to a certain logic. Because of the many functions of the car, there are many controllers, and it is difficult to build them.

2.? Test scripting

The process of scripting is more like using simulink in matlab (simply put, it is the feeling of building blocks), and converting existing test cases into a scripting language tests the engineer's test logic. The main use of several basic languages (e.g., set, if, wait, etc.) to automate the test cases, but also through their own into to realize the complexity of the function (such as vector in the CAPL language).

3.? Script debugging

After writing an automated test script, it is necessary to integrate the test script with the already built stage for debugging, to see if the executor is tested according to its own design, and if there is an error, the script needs to be adjusted or the harness connection needs to be changed. Some new features, such as the hidden door handle function and NFC function, are relatively new and take some time to test.

4. Formal testing ?

Traditional OEMs have much less workload after this step, but new car-making forces, such as Xiaopeng Automobile, Weimar, Azure, and other Internet automobile companies that we often hear about, have very fast updating of the controller functions, so the scripts and hardware of the bench need to be changed frequently as well.
