摘要： Transmitters of a tire condition monitoring apparatus that monitors condition of vehicle tires. Each transmitter has a measuring sensor, a transmission circuit, a vehicle speed sensor and a controller. The measuring sensor measures condition of the corresponding tire. The transmission circuit periodically transmits data representing the tire condition. The vehicle speed sensor detects moving of the vehicle. The controller sets a delay time, the delay time being a period from when the vehicle speed sensor detects moving of the vehicle to when the data representing the condition of the corresponding tire is transmitted. The delay time varies from one transmitter to another.

摘要： A transmitter, which is operated by a battery, wirelessly transmits data including data that represents the temperature T in a tire and data that represents the voltage V of the battery. A receiver judges whether or not the life of the battery is ending depending on the battery voltage V read from the received data. More specifically, the receiver performs the judgment regarding the life of the battery based on a comparison between the battery voltage V and a variable voltage reference value V0, which is selected in accordance with the temperature T in the tire. The judgment regarding the life of the battery is thus accurately performed.

摘要： A tire condition monitoring apparatus that improves data communication accuracy. Permanent magnets are fixed to the wheel well. A transmitter fixed to a tire includes a pressure sensor for detecting the air pressure of the tire and an MI sensor for detecting magnetic fields generated by the permanent magnets. As the tire rotates, the positions of the permanent magnets relative to the MI sensor change. Thus, the intensity of the magnetic field acting on the MI sensor changes. The transmitter determines the rotation angle of the tire based on the detection of the MI sensor. When the rotation angle of the tire is in a range optimal for wireless communication, the transmitter transmits the air pressure data generated by the pressure sensor.
