A Study on Vehicle Cornering Characteristics Using Model Considering Limited-Slip Differential Mechanism in Rear Wheel

Abstract

In the cornering behavior of a vehicle, the differential connecting the left and right wheels is not negligible. In this study, to clarify the handling characteristics of a rear-wheel-drive vehicle in the locked and slipping states of the differential including lateral load transfer, derivatives for yaw damping during cornering and yaw moment change when a driving force is applied were derived from a linear 2 degrees of freedom 3-wheels vehicle model, and their effects on handling characteristics were discussed.
