Abstract
A tire pressure monitoring system, that includes a plurality of the wheel state detection unit, provided at wheel of a vehicle, and that transmits detected wheel state information. A request signal transmitter transmits a request signal to request transmission of the detected wheel state information. When each wheel state detection unit receives the request signal, it transmits the detected wheel state together with the indication information indicating that the wheel state is detected in response to the transmission request signal. The ECU sets a determination threshold value for triggering an alert regarding tire pressure based on the detected wheel state information transmitted from the plurality of wheel state detection units.
