Id registration method for tire pressure sensor, id registration apparatus, id registration tool for tire pressure monitoring system, and tire with air pressure sensor

Abstract

Provided is a tire pressure monitoring system capable of preventing mistaken registration of ID due to radio interference. In the system, a tire pressure monitoring apparatus is switched into an ID registration mode while an ID is read out from a bar code or the like and is transmitted to the tire pressure monitoring apparatus. The tire pressure monitoring apparatus registers the received ID in a memory. After the completion of the registration of a necessary number of IDs, the tire pressure monitoring apparatus is switched into a normal mode, before the ID registration operation comes to an end. On the other hand, in the case of tire replacement, through the use of an ID registration tool, an ID is read out from a bar code adhered onto a tire detached and is transmitted to the tire pressure monitoring apparatus. The tire pressure monitoring apparatus removes an ID corresponding to this ID from the memory, and through the use of the ID registration tool, an ID is read out from a bar code adhered onto a tire to be newly mounted and is transmitted to the tire pressure monitoring apparatus to be registered therein.
