Correlation and Evaluation of Driver/Vehicle Directional Handling Data

Results of a study to analyze and correlate handling-related driver/vehicle system response and performance data are reported. Steering control tasks involving maneuvers and disturbance regulation are emphasized. Correlations between vehicle handling parameters, objective measures, and subjective rating data have been made. These have lead to the tentative definition of values of steering gain and effective yaw time constant which are preferred for satisfactory handling qualities and performance for passenger automobiles.
