STUDY OF VEHICLE STEERING AND RESPONSE CHARACTERISTICS IN SIMULATED AND ACTUAL DRIVING

Simulator characteristics were matched to those of the full-scale vehicle with respect to steering torque gradient, control sensitivity, and lateral acceleration response time; identical disturbance signals were applied to each facility. The influence of torque gradient was accentuated in the Simulator and at low levels of control sensitivity, with high levels of torque gradient producing smaller steering wheel and vehicle motion deviations. The effect of control sensitivity on steering wheel deviations was accentuated under actual driving conditions and for slower response times. A greater improvement in lateral position deviations with increased control sensitivity was noted for the slow response time configurations. Even though there were statistically significant interactions involving simulated versus actual driving conditions, examination of the data indicates that the performance trends are essentially the same in both facilities.
