Tire air pressure monitoring device
First Claim
1. A tire air pressure monitoring device comprising:
- a receiving component configured to wirelessly receives a detected function code, an ID code, and tire air pressure data for each wheel of a vehicle;
an ID code registration determining component configured to determine an ID code registration method based on a rotational state of the wheels;
a function code setting component configured to set a reference function code based on said ID code registration method determined by said ID code registration determining component when said reference function code corresponds to said detected function code of said receiving component; and
an ID code registration component configured to register said ID codes of the wheels based on said reference function code set by said function code setting component.

Abstract
A tire air pressure monitoring device is inexpensively constructed, and avoids misregistering ID codes from other vehicles by using a receiver that determines the ID code registration method based on the speed of the vehicle, and a function code setting process that sets the function code of the data intended for ID code registration based on the results of the ID code registration method determining process. The receiver identifies data intended for ID code registration by the function code, and then registers the ID code. Further, the receiver has an ID code permutation comparison process that permutes the ID codes received from a plurality of transmitters to form ID code permutation blocks. The receiver compares the ID code permutations of consecutive ID code permutation blocks, and registers the ID codes when the ID code permutations are the same in two consecutive ID code permutation blocks.
