PROBLEM TO BE SOLVED: To provide a tire condition monitoring device that is able to individually monitor each of tire conditions by means of a simple configuration.SOLUTION: A tire condition monitoring device comprises: condition detection means arranged on tires 1, 2, 3, and 4 attached to the corresponding wheels of a vehicle; transmission means that transmits, by means of an electric wave, a detected condition result obtained by the corresponding condition detection means; reception means that receives the detected-condition results from the plurality of transmission means; control means 40 in which a signal from the reception means is input; and magnetic materials disposed near the tires 1, 2, 3, and 4; and magnetic detection means that detects the magnetic field of each magnetic body. The magnetic materials are disposed in places fewer than the places where the tires 1, 2, 3, and 4 are arranged. The transmission means transmits a detected magnetic field result obtained by the magnetic detection means and identification information allotted to the condition detection means. The control means 40 acquires the rotation angle of each wheel from rotation angle detection means 50 provided on the vehicle, and determines, from the rotation angle and the detected magnetic field result, from which one of the tires 1, 2, 3, and 4 the detected condition result has been acquired.SELECTED DRAWING: Figure 2 |
