Vehicle tire information obtaining apparatus and tire information processing apparatus

摘要

A vehicle tire information processing apparatus for processing tire information of tires mounted on the axles of a vehicle and a non-mounted tire carried by the vehicle, comprising tire state detectors; transmitters provided in the respective tires which transmit tire data sets; a receiver provided in the body of the vehicle for receiving the tire data sets; a non-mounted-tire information determining portion which determines whether the tire data sets have been transmitted from the non-mounted tire; and a data processor which processes the tire data sets in a first manner in a first case in which one of the tire data sets can be determined to have been transmitted from the non-mounted tire by distinguishing the tire data sets from each other; and which processes the tire data sets in a second manner in a second case in which none of the tire data sets can be determined to have been transmitted from the non-mounted tire equally irrespective of whether they have been transmitted from the mounted or the non-mounted tire.
