Problems solved by technology

[0003] Traditional testing mainly relies on manpower. Due to the complex structure and many functions of the automatic driving controller, the use of manual testing has the problems of high testing cost, labor cost and time cost, and the level and experience of testers are relatively high. High, it takes a lot of time and effort, and the accuracy of the test results is also low
