Abstract: A wheel provided with a tire sensor unit having a sensor and a radio transmitter. The sensor detects a pressure and temperature of a tire, and generates a tire pressure data signal and a tire temperature data signal based on the pressure and temperature of the tire. The radio transmitter generates a data signal including the tire pressure data signal and the tire temperature data signal, and transmits the data signal by wireless.

Abstract: Door opening and closing control information transmitted from a portable transmitter 3 is received at a receiving apparatus 20 to drive a door locking mechanism 4. A tire sensor unit 10 mounted on each tire 2 detects tire pressure and tire internal temperature and radio-transmits those data and identification information. A signal transmitted from the tire sensor unit 10 is received at the receiving device 20 to be supplied to a display device 30. A tire abnormality judging section 31 lights a warning lamp 32 when the air pressure drops to the lower level than an air pressure drop detecting threshold value and the temperature is higher than a temperature rise detecting threshold value. The tire abnormality judging section 31 also sounds an alarm buzzer 33 to inform the tire abnormality.

Abstract: According to the present invention, there is provided a tire monitoring system in which electric power is fed from a car body to a tire sensor unit in a non-contact manner. The tire sensor unit 10 (10a-10d) is mounted on a corresponding tire 2 (2a-2d) of a car, and electric power is radio-transmitted from a corresponding non-contact type power supply portion 40 (40a-40d) provided in the car body to the tire sensor unit 10 by electromagnetic induction or by microwaves. The tire sensor unit 10 is provided with a non-contact type power receiving portion which generates direct-current power by energy transmitted from the non-contact type power supply portion 40 so as to supply electric power necessary for activating the tire sensor unit 10. The tire sensor unit 10 senses air pressure or the like, and radio-transmits the information to the receiving device 20.
