The Research of Drivability Evaluation Index and Quantitative Method 2016-01-1906

The application of energy efficient technologies reduces the driving qualities of vehicles. Taking subjective evaluation methods to evaluate vehicle qualities is costly, poor reproducibility, seriously affecting the vehicle calibration cycle. In order to overcome the drawbacks of the subjective evaluation methods, this paper analyzes the characteristics of the content of drivability evaluation, and the subjective evaluation system is modified for an objective evaluation system. A Fuzzy Hierarchy quantization method is proposed based on AHP (Analysis Hierarchy Progress) and Fuzzy comprehensive method to quantify the content of drivability evaluation. This paper studied the topology relationship of subjective evaluation and vehicle performance parameters, and the drivability model of objective evaluation; the Fuzzy AHP combined with expert experience, the right weight of valuation indexes for quantitative analysis, and the model of objective evaluation are established based on Hierarchy Fuzzy Method. Experimental results show that the proposed method can achieve the objective evaluation of drivability and can be more rapid feedback drivability to further guidance on calibration.
