SIMULATOR STUDIES OF THE DRIVER'S DYNAMIC RESPONSE IN STEERING CONTROL TASKS - WITH DISCUSSION AND CLOSURE

THE UCLA DRIVING SIMULATOR, FEATURING MOVING MODEL LANDSCAPE AND TV-PROJECTED ROADWAY IMAGE, HAS BEEN USED TO STUDY DRIVER STEERING CONTROL IN OVERTAKING AND PASSING MANEUVERS AND RANDOM GUST REGULATION TASKS. THE SIMULATOR EVOKES SIMILAR CONTROL RESPONSE FROM THE SAME SUBJECTS IN EQUIVALENT TASKS, CONFIRMING ITS REALISM AND UTILITY. THE DRIVER IS SEATED IN A CAR MOUNTED ON A CHASSIS DYNAMOMETER WHOSE SPEED DETERMINES THE LANDSCAPE VELOCITY RELATIVE TO THE CAMERA. THE DRIVER'S STEERING OUTPUT IS FED TO AN ANALOG COMPUTER THAT CONTAINS THE VEHICLE EQUATIONS OF MOTION, AND ITS PARAMETERS DEFINE THE VEHICLE'S HANDLING PROPERTIES. THE CAMERA HAS LATERAL POSITION AND HEADING DEGREES OF FREEDOM CORRESPONDING TO MOTIONS OF THE SUBJECT VEHICLE. THE EXPERIMENTAL SERIES INVOLVED DRIVER STEERING CONTROL TO REGULATE THE CAR DURING RANDOM-APPEARING CROSSWIND GUSTS AND TO MAINTAIN THE CAR IN THE CENTER OF THE LANE ON A TANGENT ROADWAY. THE DYNAMIC RESPONSE PROPERTIES OF 5 SUBJECTS WERE MEASURED AS QUASI-LINEAR DESCRIBING FUNCTIONS. ALTHOUGH THE DATA ARE EXPLORATORY, THEY DO SHOW FAIRLY CONSISTENT VALUES OF DRIVER TIME DELAY AND CONTROL RESPONSE BANDWIDTH AMONG SUBJECTS AND GOOD REPEATABILITY WITH THE SAME SUBJECT ON SUCCESSIVE RUNS. THE DATA ARE CONSISTENT WITH PREVIOUSLY PUBLISHED MODELS FOR DRIVER STEERING CONTROL, AND THEY PROVIDE SOME INSIGHT INTO THE PERCEPTUAL FEEDBACK THAT THE DRIVER MAY BE USING. /AUTHOR/
