Tire status monitoring apparatus
First Claim
1. A tire status monitoring apparatus for monitoring statuses of a plurality of tires provided on a vehicle, the tire status monitoring apparatus comprising:
- transponders provided on the respective tires which detect statuses of the tires in response to a request signal and generate transponder data including data indicative of the statuses of the tires detected; and
a transceiver which transmits the request signal to each transponder, receives the transponder data from each transponder, and determines the number of times the request signal is transmitted per unit time in accordance with speed of the vehicle.

Abstract
A tire status monitoring apparatus capable of providing notification of an abnormal status for a tire in accordance with the speed of a vehicle. The tire status monitoring apparatus includes transponders which are provided on the respective tires, detect statuses of the tires in response to a request signal and generate transponder data including data indicative of the statuses of the tires detected, and a transceiver which transmits the request signal to each transponder and receives the transponder data from each transponder. The transceiver determines the number of times the request signal is transmitted per unit time in accordance with the speed of the vehicle.

9. A method of monitoring statuses of a plurality of tires provided on a vehicle wherein each tire includes a transponder which generates transponder data including data indicative of the statuses of the tire and the vehicle includes a transceiver which receives the transponder data from each transponder, the method comprising the steps of:
-
detecting the speed of the vehicle;
determining the number of times a request signal is transmitted per unit time to the plurality of tires in accordance with the detected speed of the vehicle;
transmitting the request signal to each transponder from the transceiver by the decided number of transmissions of the request signal per unit time;
causing the transponders to detect the statuses of the tires in response to the request signal and generate the transponder data; and
transmitting the transponder data to the transceiver. - View Dependent Claims (10, 11)
