基于灰色关联度法的汽车转向操纵动态特性评价

Evaluation of Dynamic Characteristic of Vehicle Steering Control Based on Gray Correlation Method

为解决汽车转向操纵动态特性的评价问题,提出了一种主观评价汽车转向操纵动态特性的综合评价方法。针对在主观评价中,专家所打的分数无法避免个人因素的影响而具有一定灰色性与模糊性的问题,采用灰色关联度法处理专家所打的分数,并通过模糊数学方法来计算汽车转向操纵动态特性的综合得分。最后,通过实例计算,比较了采用该方法得到的汽车转向操纵动态特性的计算结果与实际专家平均打分结果,验证了该评价方法的正确性与可行性。

In order to solve the problem of how to evaluate the dynamic characteristic of vehicle steering control, an integrated subjective evaluation method was presented. Because of the personal factors the subjective evaluation results of experts have both gray characteristics and fuzziness, gray correlation method was used to dispose the subjective evaluation results of experts. Then the final e- valuation result of the dynamic characteristic of vehicle steering control was calculated through fuzzy mathematics. Finally, the correctness and feasibility of this method was verified through an example calculation.
