摘要：

对驾驶员理想转向盘力矩的影响因素进行分析,提出了一种用以描述稳态转向工况的驾驶员理想转向盘力矩模型。针对三款不同型号车辆进行驾驶员转向盘力矩道路试验, 建立了中国西南地区驾驶员理想转向盘力矩模型，研究结果表明: 一定车速下，驾驶员理想转向盘力矩是转向盘转角或者侧向加速度的增函数，但随着转向盘转角或者侧向加速度的增大，驾驶员理想转向盘力矩增大的程度减缓；一定转向盘转角或者侧向加速度下，驾驶员的理想转向盘力矩与速度近似成线性正比关系；如果车辆的体积、车重相近，道路条件相同，驾驶员理想转向盘力矩与车辆的型号无关。

Abstract:

The ideal steering wheel effort characteristics of driver were analyzed and a model was put forward to describe the characteristics in the working conditions of steady state steering. The ideal steering wheel effort model for drivers in southwest China was established based on the road test results of three different vehicles. The results show: ideal steering wheel effort of driver is an increasing function of steering wheel angle or vehicle lateral acceleration when driving at a certain speed, but the increasing rate is become slower as steering wheel angle or vehicle lateral acceleration become larger. Under the condition of the same steering wheel angle or lateral acceleration, ideal steering wheel effort of driver is almost linearly proportional to the vehicle speed. When driving on the same road, driver's ideal steering wheel effort is barely related to the vehicle type if these vehicles' volume and weight are close.

Key words: steering wheel torque, road feel, lateral acceleration, electric power assist steering system, assist characteristic curve
