Research of Evaluation Parameters on the Operating Performance of Steering Column Switches Based on Discrete Analysis

Abstract

By analyzing the shifting process of steeringcolumn switches, select the inflection point force, shift force, the difference between the force, down gradient, displacement as performance evaluation parameters of steeringcolumn switches.Tested and acquisition operating characteristic curve of 100 subjective assessment for steering column switches quality, and extracting the corresponding parameters of operation performance evaluation for discrete analysis. Determine the degree of influence on the performance of the dispersion according to each evaluation parameter. On this basis points out, the paper puts forward the on-line rapid detection method of automobile Steering column switches operating performance.
