Wheel condition monitoring system and wheel position detection method

摘要

A wheel condition monitoring system includes a plurality of transmitters; a receiver; an antenna directivity control unit; a memory unit; and a wheel position determination unit. The transmitters are at each wheel of the vehicle, and transmit signals that include wheel condition data and identification data of themselves. The receiver receives the transmission signals so that the wheel condition monitoring system monitors the conditions of the respective wheels based thereon. The antenna directivity control unit controls the antenna directivity of the receiver. The memory unit stores the identification data by assigning relations between the identification data and the position of the corresponding wheel. The wheel position determination unit determines the position of the wheel at which the transmitter is installed based on the relations.
