Abstract:
1. A tire pressure detecting apparatus for a vehicle having a body and a plurality of wheels with tires, the tire pressure detecting apparatus comprising: a transmitter being integrated to each of the plurality of wheels, the transmitter including a first control unit, the first control unit detecting tire pressure of the wheel, the first control unit generating and transmitting a frame including identification information specific to the transmitter and tire pressure information regarding the tire pressure detected; and a receiver being integrated to the body, the receiver including a second control unit, the second control unit receiving the frame transmitted from the transmitter through an antenna, the second control unit performing a wheel position detection to specify a wheel position indicating which of the wheels the transmitter transmitting the frame is integrated to and to store a relationship between the wheel position specified and the identification information of the transmitter, as a wheel position relationship, the second control unit permitting an indicator to indicate tire pressure provided by the tire pressure information included in the frame while specifying the wheel, based on the wheel position relationship stored in the wheel position detection, wherein until a current wheel position detection finishes, when a difference of tire pressure of the wheels provided by the tire pressure information stored in the frames is equal to or less than a threshold, the second control unit permits the indicator to indicate the tire pressure based on a previous wheel position, as a provisional wheel position, that is provided by a previous wheel position relationship stored in a previous wheel position detection.
