A tire valve registration system including: a plurality of tire valves that are respectively installed on a plurality of tires and on a spare tire and that each transmit a radio signal that includes a valve ID and data on tire air pressure; and a receiver that is provided to a vehicle body and that is capable of receiving the radio signal from each of the plurality of tire valves. The system includes: a spare tire ID collecting unit that collects, as at least one spare tire candidate ID, the valve ID of at least one radio signal received by the receiver; and a spare tire ID confirming unit that confirms the ID of the spare tire.

A vehicle wheel information acquiring device includes a vehicle wheel sensor and a vehicle-body-side device. The vehicle wheel sensor is configured to revolve around an axle with a rotation of a vehicle wheel. The vehicle-body-side device includes a reception unit, a processing unit, a rotation position acquiring unit, an on-reception rotation position storage unit, and a determination unit. The determination unit is configured to determine whether a revolution position of the vehicle wheel sensor is included in an insufficient received intensity area during a stopping operation of a vehicle.

The present disclosure relates to a tire rotation imbalance detection device and method, and a vehicle provided therewith. A device according to one embodiment of the present disclosure is a device provided in a vehicle, including a memory and a processor configured to perform processing to detect whether tire rotation imbalance occurs using information stored in the memory. The processor is configured to identify an angular velocity () of each of a plurality of tires of the vehicle over time using a sensor signal from a wheel speed sensor installed on the tire, perform Fourier transform on the angular velocity (), and determine whether tire rotation is imbalanced based on signal magnitudes of frequency signals included in a reference region according to the Fourier transform in a frequency domain.
