摘要

摘要: 在对相关文献路感概念及人对车辆操控心理感受强度特性分析的基础上,提出了考虑方向盘力矩及转角大小的综合路感强度概念。以韦伯-费希纳定律为指导,利用综合路感强度与车辆转向响应强度的对应关系给出了方向盘理想力矩的计算方法,并进行了实例计算。对计算转矩与文献试验驾驶员方向盘力矩偏爱数据进行了对比分析,探讨了车辆转向响应强度的改进计算方法。计算数据与文献试验数据的对比分析表明本文提出的方向盘理想力矩的理论计算方法是合理可行的。

Abstract: On the basis road feel concept and human psychological feeling characteristics in vehicle handling, a comprehensive road feel concept, which takes steering wheel torque and angle into account, is proposed. According to Weber-Fischna's law and the corresponding relationship between road feel and vehicle response, a method to cal-culate the desired steering wheel torque is presented in this paper. The desired steering wheel torque in various driving conditions is calculated and the results are compared with the experiment ones of literatures. To improve the calculation accuracy, a revised method to compute the intensity of vehicle response is discussed. The comparisons of results demonstrate the feasibility of the proposed method.
