With the involvement of SBW system, a total of 12 extensively distributed force feedback characteristics for on-center steering are generated by specific arrangement of adjustable parameters. These characteristics are rated subjectively by 12 drivers in a driving simulator and meanwhile are simulated off-line objectively in accordance with international standards of on-center weave test and transition test. Then the correlations between subjective evaluation items and objective evaluation indices are analysed by multiple regression and logarithmic regression. The results show that for each subjective evaluation item, the mean absolute proportional error of the ratings predicted by each correlation equation is less than 4 %. The proposed methodology can acquire reliable correlations between subjective and objective evaluations and has potentials to be extended to cover other aspects of handling quality.
