摘要:

制动踏板感觉直接影响到制动安全性和驾驶舒适性,为准确可靠地描述汽车的制动踏板感觉,本文中提出了一种基于主客观综合赋权法的制动踏板感觉评价方法。首先通过实车试验获得各项评价指标的主观评分和客观测试数据;接着构建制动踏板感觉分层结构模型,并基于三角模糊层次分析法得到主观权重,基于熵值法得到客观权重,之后基于主客观综合赋权法得到综合权重;最后引用模糊综合评价理论得到试验车踏板感觉评价得分与隶属度等级,并与制动感觉指数评价方法对比来验证评价结果的有效性。结果表明:本文中提出的基于主客观综合赋权法的制动踏板感觉评价体系确立了统一的试验工况和主观评分标准,可以把主观评分和客观数据有机结合,实现无量纲标准化的制动踏板感觉评价结果表达。

Abstract:

The brake pedal feeling directly affects braking safety and driving comfort. In order to accurately and reliably describe the brake pedal feeling of the vehicle, this paper proposes a brake pedal feel evaluation method based on the subjective and objective comprehensive weighting method. Firstly, the subjective scores and objective test data of each evaluation index are obtained through real?vehicle experiments. Then, the hierarchical structure model of brake pedal feeling is built, and the subjective weight is obtained based on the triangular fuzzy analytic hierarchy process, the objective weight is obtained based on the entropy method, and the comprehensive weight is obtained based on the subjective and objective comprehensive weighting method. Finally, the fuzzy comprehensive evaluation theory is used to obtain the pedal feeling evaluation score and the membership grade of the test car, and the effectiveness of the evaluation results is verified by comparing with the brake feeling index evaluation method. The results show that the brake pedal feeling evaluation system based on the subjective and objective comprehensive weighting method proposed in this paper establishes a unified test condition and subjective scoring standard, which integrates subjective scoring and objective data to achieve a dimensionless and standardized expression of brake pedal feeling evaluation results.
