Driver Model of Steering Based on Target Position and Orientation 950166

A driver model of steering is developed using quartic prediction curve and dual sight distances. The target orientation and position information is incorporated into the quartic prediction curve. The model assumes that the driver gazes on a fixed point if it is a point of concern. Upon reaching a minimum distance, the driver's gaze shifts to normal.Driving simulation were conducted on a workstation with stereo vision of road consisting of straight line segments joined with angles of 5, 10 or 15 degrees. Five subjects performed driving simulation with 3 DOF model of a passenger car at the constant speed of 15 m/s. Model parameters are obtained through the curve fitting of the driver model to the experimental data. The results shows that the distances and time delay change predictably according to the road curvature.
