Abstract:

Based on improved fuzzy-AHP, a certain vehicle was evaluated and the weights of subjective evaluation indexes were obtained through real vehicle evaluation test. Cooperated with the weights and the subjective evaluation the overall performance results were
obtained.The results show that the proposed method can provide a scientific reference for the vehicle designer to control the structure parameters of the vehicle,making it be suitable for driving and enough active safety.

Key words: vehicle, handling and stability, subjective evaluation, analytic hierarchy process(AHP), fuzzy comprehensive evaluation

摘要：

基于改进的模糊层次分析方法(fuzzy-AHP)，对某款车型进行了主观评价试验。通过经验丰富的驾驶员对该车型指标层指标进行主观评分，并将其与已确定的权重系数相结合，得到操纵稳定性的总体性能评价结果。研究结果可以帮助汽车设计人员合理地控制汽车的结构参数，使之既适合于驾驶员驾驶又具有足够的主动安全性。
