A TWO LEVEL MODEL OF HUMAN STEERING BEHAVIOR IN A MOTOR VEHICLE
EIN ZWEI-EBENEN-MODELL DES MENSCHLICHEN LENKVERHALTENS IM KRAFTFAHRZEUG
In establishing design criteria for vehicle dynamics which may improve the performance of the driver-vehicle system, a quantitative description of driver steering behavior was formulated. The steering task was divided into two levels. The guidance level, involving the perception of the instantaneous and future course of the forcing function provided by the forward view of the road and the response to it in an anticipatory open-loop control mode, and the stabilization level, whereby any occurring deviations from the forcing function are compensated for in a closed-loop control mode. This concept of the quality of the driver's steering activity led to a two-level mathematical model of driver steering behavior. Its parameters were identified on the basis of data measured in driving simulator experiments. The parameter estimates of both levels of the model show significant dependence on the experimental situation which can be characterized by variables such as vehicle speed and desired path curvature.
