  • Publication number: 20170050476
    Abstract: A tire-monitoring device is arranged on a tire and includes a tire pressure sensor and a temperature sensor respectively sense tire pressure and temperature and respectively generate a tire pressure signal and a temperature signal received by a controller. When the controller determines that the tire pressure value continuously varies for a preset period or determines that a rising variation of the temperature value is larger than a preset variation, the controller generates a transmission control signal received by a wireless transmitter. The wireless transmitter transmits the tire pressure signal and the temperature signal to an external device, so as to display the tire pressure value and the temperature value. The present invention directly observes that the vehicle has started according to the continual variation of the tire pressure value and the variation of the temperature value and notifies the transmitter that the transmitter transmits the signal.
