✦ Synopsis

This paper presents a measurement method of the normalized equivalent cornering sti!ness (normalized C N

), which dominates a vehicle's steering responses. First, the method measures rear normalized C N 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 C N from yaw velocity gain. Last, the measured normalized C N 's of various vehicles are plotted on a distribution map, which indicates steering responses of each vehicle.
