THE EFFECT OF PAVEMENT ROUGHNESS ON SAFE VEHICLE HANDLING CHARACTERISTICS

A SIMPLE MATHEMATICAL MODEL IS SELECTED TO REPRESENT THE VEHICLE, AND PAVEMENT ROUGHNESS IS INTRODUCED IN THE FORM OF TIME-VARYING DYNAMIC TIRE FORCES. THE PATH OF THE VEHICLE IS DETERMINED FOR A STEP STEER ANGLE INPUT FOR DIFFERENT VEHICLE PARAMETERS AND PAVEMENT ROUGHNESS. THE STEER ANGLE AND THE SIDESLIP ANGLE ARE DETERMINED FOR SELECTED PATHS AND VEHICLE PARAMETERS. IT IS CONCLUDED THAT PAVEMENT ROUGHNESS REDUCES THE FORCES THAT ARE AVAILABLE TO CONTROL THE VEHICLE. /NTIS/
