Abstract

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.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an automobile climbing test method and a test system. Background technique [0002] Vehicle test is the most important method to verify vehicle performance, and plays an important role in the process of vehicle development and verification, among which climbing performance is an important factor to measure the power of vehicle engine. [0003] The traditional car climbing test is based on the outdoor road. During the test, data collection is inconvenient. For example, the car's maximum climbing test is very difficult and dangerous, and the test accuracy is poor; the repeatability is poor. Poor and greatly affected by external environmental conditions, it is difficult to test the maximum climbability of the car. Contents of the invention [0004] (1) Technical problems to be solved [0005] The technical problem to be solved by the invention is how to accurately and effective...
