Abstract
Twelve drivers detected changes in vehicle steering sensitivity in free maneuvering of limited duration. The changes were produced by diverse means, and drivers' discrimination of changes was determined as just noticeable differences in yaw rate sensitivity. These measures were not significantly different for changes being made in steering ratio, stability factor, and vehicle speed. This result supports the hypothesis that drivers detect changes in yaw rate sensitivity when attempting to discriminate changes in steering sensitivity. Drivers readily detected changes in yaw rate sensitivity, the overall average just noticeable difference being relatively small. It is suggested that yaw rate sensitivity is an input/output quantity of fundamental importance.
