Evaluation method for realizing association between subjective data and objective data of automobile clutch

Abstract

The invention provides an evaluation method for realizing association between subjective data and objective data of an automobile clutch. The method comprises the following steps that: firstly a database is established in a control computer, and then an operator performs user login on the control computer and sets all information of the experiment; then a test driver performs user login and carries out a separation and combination process test on the automobile clutch according to system prompt, and an objective detection device records and stores the data of each detection sensor of the clutch; after the test is performed once, subjective evaluation scoring for the operating performance of the clutch is carried out, and then the subjective evaluation score is recorded into the database; and after the driver test is finished, the operator can check the test curve of the clutch, carries out contrastive analysis on the association between objective detection parameters and driver subjective evaluation score and evaluates the operating comfortability of the clutch. The method provided by the invention can be used for objectively reflecting the operating performance of different clutches and conveniently eliminating the influence of different vehicle control systems during a real vehicle test.

Description

technical field [0001] The invention belongs to the technical field of automobile clutch performance detection, and in particular relates to an evaluation method for realizing association of subjective and objective data of automobile clutches. Background technique [0002] In a mechanical transmission vehicle powered by an internal combustion engine, the clutch is an important part of the transmission system. The performance of the automobile clutch directly affects the comfort level of the driver during driving. At present, a variety of detection equipment has been developed for the performance of automobile clutches at home and abroad, including detection platforms for clutch separation characteristics and load characteristics. These detection devices use a group of sensors installed on the test bench to obtain the working parameters of the clutch. It is used to distinguish whether the clutch is qualified, but the operating comfort performance of the clutch in the car ca...

At present, a variety of detection equipment has been developed for the performance of automobile clutches at home and abroad, including detection platforms for clutch separation characteristics and load characteristics. These detection devices use a group of sensors installed on the test bench to obtain the working parameters of the clutch. It is used to distinguish whether the clutch is qualified, but the operating comfort performance of the clutch in the car cannot be obtained

The most intuitive way to judge the comfort of automobile clutch operation is to install the clutch on the automobile for real vehicle testing. This method requires each clutch to be equipped with a corresponding prototype vehicle, which is not practical, and requires the prototype vehicle to be Prior to clutch development, this method greatly limits the development of new clutches, so it is difficult to achieve in actual operation
