Method for evaluating manipulation comfort level of automobile clutch based on fuzzy association theory

Abstract

The invention relates to a method for evaluating a manipulation comfort level of an automobile clutch based on a fuzzy association theory. An objective detection device is used for collecting main performance parameters of a clutch manipulation process and an operation simulation system is used for restoring an operation environment of real driving to the greatest extent; and a data processing and analyzing system is used for analyzing detected objective data and calculating a corresponding comfortableness evaluation grade of the clutch. When the clutch is tested in the operation simulation system of a real automobile, a testing person treads a pedal of the clutch and objective performance parameter samples of one group of the clutches are obtained by the objective detection device. The data processing and analyzing system is used for utilizing a membership grade function to calculate the membership grade of each index of the samples to each evaluation grade according to a parameter variation range of each grade; then the weight of samples is combined and a clear comprehensive judgment is used as reference, so as to calculate a grey correlation degree of the samples corresponding to each grade; and the comfort level grade of the test sample clutch is determined according to the maximum principle.

Description

technical field [0001] The invention belongs to the technical field of detection of automobile clutch performance, in particular to a method for evaluating the comfort of automobile clutch control based on fuzzy correlation theory. Background technique [0002] Although the automatic transmission system is the development trend of the automobile transmission system in the world today, due to the constraints of cost and technology, the manual mechanical reducer and its dry friction clutch are still the main application components. mainstream. However, there are not many researches on the comfort of operating components, especially the research on the comfort of clutch control. Since there are many quantitative indicators for evaluating the comfort of clutch operation, and the relationship between these factors and the overall subjective evaluation standard of the driver when operating the clutch is quite complicated, and the driver's feeling of comfort also has ambiguity and...

However, there are not many studies on the comfort of operating parts, especially the research on the comfort of clutch control.

Since there are many quantitative indicators for evaluating the comfort of clutch operation, and the relationship between these factor indicators and the overall subjective evaluation criteria of the driver when operating the clutch is quite complicated, and the driver's feeling of comfort is also fuzzy and uncertain. How to fairly judge the comfort of clutch control is seldom published
