US 2023/0415524 A1 · TIRE POSITION IDENTIFICATION DEVICE AND TIRE POSITION IDENTIFICATION METHOD

Abstract

A tire position identification device is provided as a device that can identify the positions of wheels to which tires are attached by using information about other than air pressure. The tire position identification device has: deformation detection units, each of which can detect deformation of the relevant tire; a turn detection unit that can detect whether a vehicle having the tires and wheels has made a turn and can also detect the direction of the turn; a speed detection unit that can detect the speed of the vehicle, and a control unit that infers the positions of the wheels to which the tires are attached according to the deformation of the tires, the direction of the turn of the vehicle, and its speed.
