A NEW PROCEDURE FOR DETERMINING ON-THE-ROAD VEHICLE DIRECTIONAL RESPONSE CHARACTERISTICS

A NEW PROCEDURE IS DESCRIBED IN WHICH CONVENTIONAL CONTROL SYSTEM ANALYSIS TECHNIQUES ARE USED TO DERIVE THE TRANSFER FUNCTION RELATING STEER INPUT TO VEHICLE LATERAL MOTION. THE INFLUENCE OF THE DRIVER'S LIMITED TORQUE CAPABILITIES ON THE STEERING SYSTEM INPUT IS INTRODUCED. THIS APPROACH PRODUCES SOMEWHAT DIFFERENT DESCRIPTIONS OF VEHICLE RESPONSE FROM THOSE OBTAINED IN THE PAST WHEN SUCH DESCRIPTIONS DID NOT INCLUDE THIS DRIVER INFLUENCE. SINCE THE RESULTING TRANSFER FUNCTION IS A UNIQUE ON THE ROAD DESCRIPTION OF VEHICLE DYNAMICS, REALISTIC VEHICLE MOTION RESPONSE TO ANY QUANTIFIABLE STEER INPUT CAN BE COMPUTED. /HSL/
