Abstract: The electronic stability controller (ESC) system is one of the most important active safety technologies in the automotive industry in the last decade. The system can greatly improve the stability of the vehicle under some extreme driving conditions. However, due to the poor consistency of the vehicle test on snow and ice surface conditions, there are few tests on snow and ice surface for electronic stability controller system. In this paper, a typical test method of double line shifting under snow and ice surface is selected, and a large number of repeated tests are carried out under snow and ice surface. Through the analysis of data collection, we try to find out the main influencing factors and influencing rules of test consistency. From the data results, it is found that the operation error of the pilot is the main factor affecting the consistency of the test. Only after excluding this influencing factor can we further study the influence of natural conditions such as temperature, humidity and wind speed on the test results. In this case, it is an effective method to improve the consistency of the test by using robot operation and improving the driver's skills.
