汽车操纵稳定性的模糊综合评判与验证

主观评价是汽车操纵稳定性评价发展过程中的主要评价手段，基于实车试验各单项评价指标的驾驶员打分，提出一种汽车操纵稳定性的模糊综合评判方法，并将该方法对两辆样车进行评价。以三自由度汽车转向开环模型为对象，基于汽车操纵逆动力学理论，建立汽车操纵逆动力学模型并对两辆样车的操纵稳定性进行仿真分析，将其与模糊综合评判结果比较，验证模糊综合评判方法应用到汽车操纵稳定性评判的可行性。

Fuzzy Comprehensive Evaluation and Verification for Handling Stability of Vehicle

A subjective evaluation of a prototype vehicle is still a main evaluation means used in the automotive industry, and the overall performance of the scoring is more difficult. According to the scoring based on individual evaluation of the real vehicle test, a method used in fuzzy comprehensive evaluation of vehicle handling stability was presented. And the approach was applied in evaluating two prototype vehicles. Based on vehicle steering open-loop model with 3 degrees of freedom and vehicle handling inverse dynamics theory, the vehicle handling inverse dynamics model was established and the control stability of two cars were simulated and analyzed. The two results were compared to verify the feasibility of fuzzy comprehensive evaluation method applied to evaluate vehicle handling stability.
