摘要
汽车的行驶动力学性能作为汽车主动安全的重要属性,需要在汽车设计、使用等环节对其进行有效评价。汽车行驶动力学性能的主观评价方法,具有限制少、效率高、可测参数广等优点,能更好地提高汽车性能与消费者实际需求的契合度。为了对主观评价中存在矛盾性的诸多参数进行有效综合、得出具有一定区分度的评估结果,文章提出了一种基于可拓物元法的车辆动力学性能主观评价方法。首先采用最大偏差加权法将差异较大的指标赋予更大的权重;其次对传统的可拓物元法进行修正,将各指标评价中存在的矛盾问题和不一致性转换为相容问题,将评价者的主观感受转化为具有科学依据的量化数值,从而为管理者和决策者提供辅助决策。
As an important attribute of vehicles’ active safety, the dynamic performance is needed to be effectively evaluated in many occasions such as automobile design and use. The subjective assessment method has the advantages of less restrictions, high efficiency and wide measurable parameters, which can better improve the compatibility between vehicle performance and actual consumer demand. In order to effectively synthesize many contradictory parameters in subjective evaluation and obtain evaluation results with certain discrimination, a subjective assessment method based on the maximum deviation weighting method and extension matter-element method is proposed in this paper. First, feature with greater difference is assigned to larger weight by the maximum deviation weighting method. Second, contradictions and inconsistencies between evaluation indicators are converted into compatibility problems by the modified extension matter-element method. The subjective feelings of evaluators are transformed into quantitative values with scientific basis, which can provide decision support for managers and decision makers.
