Analysis of Driver and a “Four Wheel Steering Vehicle” System Using a Driving Simulator ISSN0148-7191 880641

Four wheel steering vehicle (hereafter called “4WS”) is a passenger car having simultaneously steerable front and rear wheels. But driver's desired steering control characteristics for 4WS have not been determined yet. This paper reports the driver's steering control characteristics, described by a transfer function, to various kinds of vehicles including 4WS, which were obtained by test results of a driver-vehicle system using the driving simulator. This paper also reports evaluation results about the dynamic characteristics of the vehicles from a standpoint of the driver's steering control characteristics.
