Automobile climbing testing method and system

The invention relates to the technical field of vehicles and discloses an automobile climbing testing method and system. The testing method comprises the steps: S1, a testing environment and a tested automobile are prepared before testing; S2, the tested automobile and a chassis dynamometer are preheated; S3, a road coasting test is conducted on the tested automobile and meanwhile running data in the testing process are recorded; S4, data analysis and comparison are performed according to the data recorded in the step S3 and judgment whether the climbing performance of an automobile meets the design requirement or not is made. According to the testing method, the chassis dynamometer is adopted to simulate an actual track, conduct climbing performance testing on the automobile and acquire the running data of the automobile in the testing process, the data acquisition process is simple, convenient and quick, the accuracy of acquired data are higher, the testing method is safe, and testing cost can be greatly reduced.
