摘要： A tire pressure monitoring system includes tire air pressure detectors (4), arranged on tires (2) and configured to transmit a tire air pressure signal including pressure data and a tire ID only when the tire is rotated, and a receiver (13), arranged on a vehicle body (5) and capable of receiving the signal from each tire air pressure detector (4). The receiver (13) includes a tire recognition unit (22) configured to monitor whether or not the signal is received from each tire air pressure detector (4) over fixed periods and during each fixed period, obtain a number of the fixed periods during which the signal is not received for each tire air pressure detector (4), and recognize whether each tire is a traveling tire or a spare tire based on the number of the fixed periods that is obtained for the corresponding tire air pressure detector (4).

摘要： A tire position determination system is provided with: a plurality of tire air pressure transmitters (4) respectively attached to a plurality of tires (2) and each capable of transmitting a first radio signal including air pressure data and a tire ID; a plurality of axle rotation detection units (19) respectively attached to a plurality of axles (18) and each generating axle rotation information by detecting rotation of corresponding one of the plurality of axles; and a receiver (12) mounted to a vehicle body and capable of receiving the first radio signal transmitted from each of the plurality of tire air pressure transmitters (4). Each of the plurality of tire air pressure transmitters (4) includes a specific position detection unit (19) capable of detecting the arrival of the tire air pressure transmitter (4) at a specific position on a trajectory of rotation of the tire, and a transmission control unit (20) that, based on a result of detection by the specific position detection unit (19), generates a second radio signal including data indicating the arrival of the tire air pressure transmitter (4) at the specific position on the trajectory of rotation of the tire and the ID, and that causes the second radio signal to be transmitted from the tire air pressure transmitter (4). The receiver (12) includes an axle rotation information acquisition unit (23) that acquires the axle rotation information from each of the plurality of axle rotation detection units (19) each time the second radio signal is received by the receiver, and a position determination unit (24) that determines a tire position of the plurality of tires (2) by calculating a distribution of the axle rotation information for each ID by gathering statistics about the axle rotation information for each ID and by identifying the ID of the tire that rotates in synchronism with the axle rotation information about each of the plurality of axles (18) on the basis of the distribution.
