Abstract
A tire pressure detection apparatus includes: a transmitter at each of a plurality of wheels with a tire; and a receiver at a vehicle body. The transmitter has: a sensing device having a pressure sensor outputting a detection signal related to a tire pressure of each of the plurality of wheels and an acceleration sensor detecting an acceleration including a centrifugal acceleration caused by rotation of the wheel and a gravitational acceleration; a first controller performing signal processing on the detection signal of the pressure sensor and creating a frame storing data related to the tire pressure; and a radio wave transmitter transmitting the frame. The receiver has: a radio wave receiver receiving the frame; and a second controller detecting a tire pressure based on the data related to the tire pressure stored in the received frame.
