Tire inflation pressure monitoring device
First Claim
1. A tire inflation pressure monitoring device, comprising:
- transmitters attached to respective tires of a vehicle, for transmitting air pressure signals indicative of air pressures in the tires detected by respective air pressure sensors; and
a receiver for receiving the air pressure signals from the respective transmitters, the receiver being adapted to generate a warning signal in accordance with the received air pressure signals,wherein the air pressure signal transmitted from each of the transmitters includes an ID of the corresponding transmitter as an ID signal,the receiver is capable of switching a mode thereof to an ID registration mode in which the IDs of the transmitters are registered, andduring the ID registration mode, the transmitters are forced to transmit the air pressure signals, and if the number of the air pressure signals received from the transmitters is equal to a predetermined value, the receiver registers the IDs of the transmitters based on the ID signals included in the received air pressure signals.

Abstract
A tire inflation pressure monitoring device includes transmitters for transmitting air pressure signals indicative of air pressures in tires, detected by respective air pressure sensors, and a receiver for generating a warning signal in accordance with the air pressure signals received from the transmitters. The air pressure signal transmitted from each of the transmitters includes an ID of the corresponding transmitter as an ID signal. When the receiver is in an ID registration mode in which the IDs of the transmitters are registered (S12), the transmitters are forced to transmit the air pressure signals, and if the number of the received air pressure signals is equal to a predetermined value, the receiver registers the IDs of the transmitters based on the ID signals included in the received air pressure signals (S20, S26).

-
transmitters attached to respective tires of a vehicle, for transmitting air pressure signals indicative of air pressures in the tires detected by respective air pressure sensors; and a receiver for receiving the air pressure signals from the respective transmitters, the receiver being adapted to generate a warning signal if the air pressure in any of the tires, indicated by the received air pressure signals, is equal to or lower than a predetermined value, wherein, the air pressure signal transmitted from each of the transmitters includes an ID of the corresponding transmitter as an ID signal, the receiver is capable of switching a mode thereof to an ID registration mode in which the IDs of the transmitters are registered, in the ID registration mode, actual air pressures in the tires are reduced to a value equal to or lower than the predetermined value, and if, in the ID registration mode, the air pressures in the tires, indicated by the respective air pressure signals, are equal to or lower than the predetermined value, the receiver registers the IDs of the transmitters based on the respective ID signals included in the air pressure signals. - View Dependent Claims (6, 7, 8)
