TIRE FORCE ESTIMATING DEVICE AND TIRE FORCE ESTIMATING METHOD

摘要

A tire force estimating device estimates tire forces which are forces applied from a ground surface to a wheel of a vehicle which turns in a bank state in which a vehicle body is tilted around a forward-rearward axis. The tire force estimating device includes a first tire force estimating section which estimates the force applied from the ground surface to the wheel, based on a change over time of a motion state of the vehicle body within a plane perpendicular to the forward-rearward axis.
