基于驾驶模拟器的驾驶员所偏好的转向盘力矩特性研究

Study on Steering Effort Preference of Drivers Based on Driving Simulator

利用ADSL开发型驾驶模拟器研究了在不同速度和侧向加速度下的中国驾驶员所偏好的转向盘力矩特性。研究结果表明,中国驾驶员所偏好的转向盘力矩与欧洲和日本驾驶员所偏好的转向盘力矩一致,随车速的增大而增大,在线性区域内(侧向加速度小于3m/s2),随侧向加速度的增大而明显增大,在非线性区域内(侧向加速度大于3m/s2),随侧向加速度的增大,驾驶员所偏好的转向盘力矩增大不明显。研究结果为汽车电动助力转向的助力特性设计和线控转向的路感模拟提供了依据。

This paper present the study on steering effort preference of Chinese drivers by using ADSL Driving Simulator. The steering effort preference was a function of automobile speed and lateral acceleration. The results show：Chinese driver＇s steering effort preference increases with the automobile speed, which is similar with the Europe and Japanese drivers, but the preference values is less than the values of Europe and Japanese driver＇s. The steering effort preference increases with the lateral acceleration obviously in linear region （lateral acceleration less than 3m/s^2）. But this increase is not obvious in nonlinear region （lateral acceleration more than 3m/s^2）.
