Abstract

The invention provides a vehicle braking performance evaluation method. The method comprises the following steps: when a vehicle is subjected to a braking test, collecting braking test parameters, attitude response parameters and internal parameters of a braking system of the vehicle within a period of time from braking starting to vehicle stopping; establishing a corresponding relationship amongbrake test parameters, attitude parameters, internal parameters of a brake system and time; and quantitatively evaluating the braking performance of the vehicle based on the corresponding relation ofthe braking test parameters, the attitude parameters and the internal parameters of the braking system at the same moment. According to the method, the mutual relation among the braking performance ofthe vehicle, the braking test parameters of the vehicle and the internal parameters of the braking system of the vehicle can be smoothly obtained, and then important data support and improvement basis are provided for overall improvement of the braking performance of the vehicle in the future.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle braking performance evaluation method. Background technique [0002] In order to achieve the best braking performance of the vehicle, it is usually necessary to test the braking system of the vehicle during the vehicle development process or before the vehicle leaves the factory to obtain the braking performance of the vehicle, and then to debug the vehicle. Adjust the braking performance of the vehicle to the best condition. Especially in the process of vehicle braking performance development, there are many performance parameters of the whole vehicle involved, and there are conflicts and contradictions among the performance parameters of the whole vehicle, so it is difficult to accurately calibrate each performance parameter of the whole vehicle. If the performance parameters of the vehicle are not well calibrated, it will greatly affect the braking performance of t...
