COMPUTER MODEL OF DRIVER RESPONSE

The development of a digital computer software package designed to allow the user to predict the dynamic response of a driver/vehicle system to a limited number of roadway scenarios is described. The simulation is restricted to a single vehicle travelling at constant forward speed and does not cover complex multivehicle interactions. When a driving scenario is specified, the program selects a driver model. A simulation program is used to steer the vehicle through the maneuvers necessary to complete the driving task. In this manner records of steering wheel position and vehicle trajectory are generated. Three driving scenarios are included in the present development: (1) lane tracking along a straight roadway in the presence of disturbances; (2) lane tracking along a winding roadway; and (3) the obstacle avoidance maneuver. They are basically linear differential equations which mimic the driver's steering wheel response under the conditions which hold in each driving scenario. Each module in the analysis package is described.
