The Synthetic Evaluation Method of HEV Motor Propulsion System

In order to proper evaluate the kinds of motor propulsion system of hybrid electric vehicles (HEV), and supply some proper evaluating indicator, based on a lot of test data of the motor propulsion system, the shortage of the traditional evaluation method was presented. The evaluation method was improved with the gray correlation. The comprehensive approach degree was used to evaluate the correlation among the fuzzy sets. The combination performance evaluation of motor propulsion system was fulfilled with the degree of compatibility guidelines (DCG). At the end, feasibility of the evaluation method is verified and the evaluating results can be seen as the reference of improve the motor propulsion system performance.
