Abstract

This paper presents a measurement method of the normalized equivalent cornering stiffness (normalized Cp), which dominates a vehicle's steering responses. First, the method measures rear normalized Cp from the velocity at which the sign of vehicle slip angle is reversed in steady-state turning. The method is accurate because the velocity is independent of the errors of measuring instruments. Second, the method measures front normalized Cp from yaw velocity gain. Last, the measured normalized Cp's of various vehicles are plotted on a distribution map, which indicates steering responses of each vehicle.
