EFFECTS OF AUTOMOBILE STEERING CHARACTERISTICS ON DRIVER VEHICLE SYSTEM DYNAMICS IN REGULATION TASKS
A regulation task which subjected the automobile to a random gust disturbance which is countered by driver control action is used to study the effects of various automobile steering characteristics on the driver/vehicle system. The experiments used a variable stability automobile specially configured to permit insertion of the simulated gust disturbance and the measurement of the driver/vehicle system characteristics. The tests were conducted in two phases: a broad coverage of vehicle dynamics in which over 40 configurations of vehicle steering dynamics and steering gains were tested with an expert test driver; and a validation phase which covered 6 sets of vehicle dynamics with 16 subjects. In both phases driver/vehicle system dynamics were measured and interpreted as an effective open-loop system describing function. Objectives measures of system bandwidth, stability, and time delays were deduced and compared. These objective measures were supplemented by driver ratings. A tentative optimum range of vehicle dynamics for the directional regulation task was established.
