TRACTION EFFECTS WHILE CORNERING

THE NEED TO CONSIDER AUTOMOBILE DYNAMIC PROBLEMS, IN WHICH THE VEHICLE IS SUBJECT TO LONGITUDINAL AND LATERAL FORCES SIMULTANEOUSLY, IS OUTLINED. TETHERED TESTING IS PROPOSED AS A METHOD FOR MEASURING VEHICLE BEHAVIOR UNDER THESE CONDITIONS, AND UP TO THE MAXIMUM LATERAL FORCE THAT CAN BE OBTAINED. EQUIPMENT AND DATA ANALYSIS PROCEDURES ARE DESCRIBED. IT IS SHOWN THAT THE RATE OF CHANGE OF STEER ANGLE WITH LATERAL ACCELERATION AND THE RATE OF CHANGE OF STEER ANGLE WITH SLIP ANGLE ARE SUITABLE QUANTITIES FOR CHARACTERIZING VEHICLE STEADY STATE BEHAVIOR. RESULTS ARE PRESENTED IN TERMS OF THESE QUANTITIES TO ILLUSTRATE THE EFFECTS OF COMBINED CORNERING AND TRACTION FOR FRONT AND REAR WHEEL DRIVE VEHICLES. /HSL/
