To overcome the shortcomings of subjective evaluation, there have been several studies to examine the correlations between subjective and objective evaluations of on-center steering feel, and some useful results are obtained. However, it is still not clear how to design the steering characteristic based on the correlations.
In this paper, we propose a methodology of identifying the optimal on-center steering force characteristic based on the correlations between subjective and objective evaluations. Firstly, significant correlations between subjective and objective evaluations regarding on-center steering feel are established and verified. These verified correlations are then used to design the steering force characteristic. With desired ratings of the subjective evaluation items set as optimization goals, the ideal values of objective evaluation indices are obtained by use of an optimal design method. At last, the optimal steering force characteristic is designed based on the ideal objective indices. To satisfy the requirement of different engineering applications, the desired ratings of subjective evaluation items can be adjusted accordingly. The proposed methodology shows great potential in helping engineers streamline the design and development process of the steering system.
