Abstract: In the study of vehicle road load test methods, it is found that there are certain differences in the requirements of test conditions and data processing in test regulations at home and abroad. It is unknown how much these differences can affect the test results. By collecting domestic and foreign test regulations for comparative analysis, find out the differences in various regulations, and use actual cases to illustrate the impact of differences on data processing results, which is of great significance to the research or revision of road coast down test methods.
