Patent ID: 6954687

Claim:
A method for registering identifications (IDs) of transmitters associated with respective tires of its own vehicle to a memory of a pneumatic tire pressure monitoring apparatus provided in a vehicle body, comprising the steps of: causing each transmitter to transmit variable data of an associated tire together with an ID assigned to said each transmitter, said variable data varying between a moment said vehicle is traveling and a moment said vehicle is stopped; causing said pneumatic tire pressure monitoring apparatus to receive said variable data; inputting traveling condition specifying data which specifies traveling conditions of said vehicle; registering said ID transmitted from each of said transmitters as a provisional ID of said transmitter when said traveling condition specifying data indicates that said vehicle is stopped; judging whether said provisional ID of each of said transmitters agrees with said ID transmitted from said transmitter when said traveling condition specifying data indicates that said vehicle is traveling; identifying said provisional ID of one of the transmitters associated with the tires actually installed on wheels of the vehicle based on said variable data transmitted from said transmitter when said provisional ID agrees with said ID transmitted from said transmitter; registering said identified provisional ID of said transmitter into said memory of the pneumatic tire pressure monitoring apparatus as an authorized ID of said transmitter.
