EXPERIMENTAL INVESTIGATION OF HUMAN STEERING BEHAVIOR IN A SIMULATED ROAD DRIVING TASK. PART 1

EXPERIMENTELLE UNTERSUCHUNG DES MENSCHLICHEN LENKVERHALTENS BEI SIMULIERTER STRASSENFAHRT. TEIL 1

The capabilities and limitations of the human controller substantially affect the lateral dynamics of the driver-vehicle system. The steering behavior of the driver is investigated in this paper from a control engineering viewpoint. The experimental data of six subjects who participated in a driving simulator test series are analyzed. The simulated vehicle dynamics approximated an automobile. The driving task was to guide the vehicle as closely as possible along the center line of the road at a verbally requested speed. The driver perceives the critical portion of information for the steering task from his visual field. In the driving simulator the driver's front window scene was simulated with electronically generated quasi-natural road features. The simulated road image consisted of the dotted centerline, the road borders with side posts and a horizontal scene. The information which the driver receives from the complex visual scene may be distinguished into two types which are relevant to two aspects of the driving process: 1. Information on the instantaneous and future course of the forcing function (i.e. road center line) which is contained in the front part of the road. The relevant quantity used in the control engineering concept is the desired path curvature derived from the deterministic run of the road centerline. 2. Information on derivations between the forcing function and the vehicle's actual path. The relevant quantities used are path curvature error, heading angle and lateral deviation from centerline. The derivation of these quantities implied in the visual perception process is discussed in detail on the basis of flowing velocity vector fields and stationary perspective road patterns appearing under certain conditions in these velocity vector fields.
