PROBLEM TO BE SOLVED: To provide a tire valve ID registration system that can quickly complete a tire valve ID registration of own vehicle to a receiver.SOLUTION: Upon a change in a determination result of vehicle 1's travel or stop based on detection signals in a gravity detection part 9, tire valves 4 send radio waves Sva within a fixed time (within "16 s" that is a gravity monitoring interval). By utilizing operations of the tire valves 4, a travel determination of the vehicle 1 is also carried out in a TPMS (Tire Pressure Monitoring System) receiver 12 on the basis of a vehicle information Sv. Valve IDs, that can be received by the TPMS receiver 12 within a fixed time (e.g. equivalent to "16 s" ) after the determination result that a travel determination has shifted, are treated as IDs that have a high possibility of being the valve IDs of own vehicle. In this way, the valve IDs of own vehicle's tires are determined. |
