TIRE AIR PRESSURE DETECTION DEVICE

A tire air pressure detection device includes a plurality of transceivers and a receiver. The plurality of transceivers are correspondingly provided in a plurality of wheels of a vehicle. Each wheel has a tire. The receiver is attached to a vehicle body. Each of the plurality of transceivers outputs a detection signal indicative of an air pressure of the tire of the corresponding wheel. Each of the plurality of transceivers processes the detection signal, and generates a frame storing the processed detection signal as data related to the air pressure of the tire. The receiver receives the frame. The receiver detects the air pressure of the tire based on the data stored in the received frame.
