Abstract: 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.
