Tire pressure monitoring system

摘要

A tire pressure monitoring system driven by a battery power source allowing radio transmission of a monitor signal of a detection value of tire pressure detected by a sensor. The transmission is to the vehicle via a transmitting section in the monitoring system. A control section in the system compares the detection value from the sensor with a set value, and based on a comparison result, controls radio transmission of the monitor signal by the transmitting section. Prior to normal radio transmission of the monitor signal, radio transmission of the monitor signal is controlled by the control section. The sensor preferably comprises a temperature sensor.
