本文中对中间位置转向力特性主客观评价的相关性进行了研究。首先基于线控转向系统，针对中间位置转向建立了一个参数可调的转向力特性模型，运用均匀试验设计方法分析了12种不同的中间位置转向力特性。评价人员在驾驶模拟器上对这12种不同转向力特性进行了主观评价。同时，通过离线仿真，按照ISO中间位置操纵特性试验方法对这12组力特性进行了客观评价试验。然后应用多元线性回归方法分析主观评价项目与客观评价指标之间的相关性。结果表明，应用建立的相关性对主观评分进行预测的平均相对误差小于4%。最后，基于所建立的多元线性回归模型求取了关键客观评价指标的理想值。该方法可有效地指导转向系统的开发。

The correlations between subjective and objective evaluations of on-center steering force charac-teristics are studied in this paper. Firstly based on steering by wire system, a steering force characteristics model with adjustable parameters is built for on-center steering, and with uniform experimental design technique, 12 differ-ent on-center steering force characteristics are analyzed, then on which a subjective evaluation is performed by eval-uators on driving simulator. Meanwhile, an objective evaluation is also carried out by off-line simulation according to the relevant international standards of ISO. Then the correlation between subjective evaluation items and objective e-valuation indicators is analyzed by applying multivariate linear regression method. The results show that the average relative error of subjective ratings predicted by the correlation established is less than 4%. Finally, the ideal values of key objective indicators are obtained based on the multivariate linear regression model built. The method proposed provides an effective guide to the development of steering system.
