Tire pressure monitoring system and method
First Claim
1. A tire pressure monitoring system comprising:
- a tire pressure detecting device attached to each of tires of a vehicle and detecting a tire pressure;
a transmitting device that transmits radio signals indicative of a detected tire pressure of each tire and each corresponding ID code provided to each tire separately;
a receiving device attached to a vehicle body side and receiving the radio signals from the transmitting device; and
a controller that controls a tire deflation warning;
the controller including;
an ID code registration section that registers the ID code of each tire by updating data stored in a memory; and
a jack-up determination section that determines whether the vehicle has been jacked up;
wherein the ID code registration section performs registration of the ID code of each tire when the jack-up determination section determines that the vehicle has been jacked up.

Abstract
A tire pressure monitoring system includes a tire pressure detecting device attached to each of tires of a vehicle and detecting a tire pressure, a transmitting device that transmits radio signals indicative of a detected tire pressure of each tire and each corresponding ID code provided to each tire separately, a receiving device attached to a vehicle body side and receiving the radio signals from the transmitting device, and a controller that controls a tire deflation warning. The controller includes an ID code registration section that registers the ID code of each tire by updating data stored in a memory, and a jack-up determination section that determines whether the vehicle has been jacked up. The ID code registration section performs registration of the ID code of each tire when the jack-up determination section determines that the vehicle has been jacked up. A tire pressure monitoring method is also provided.

a vehicle speed detecting device that detects a vehicle speed; and
a vehicle height detecting device that detects a vehicle height at each position where each tire is disposed;
wherein the jack-up determination section determines that one of the tires has been changed with the vehicle being jacked up if a condition of a vehicle speed being zero has continued a predetermined time and if a variation of the vehicle height equal to or larger than a predetermined value has occurred before lapse of the predetermined time after stoppage of the vehicle.

3. A tire pressure monitoring system according to claim 2, wherein the ID code registration section enters an ID code registration mode if the jack-up determination section determines that one of the tires has been changed with the vehicle being jacked and thereafter the vehicle speed becomes higher than a predetermined value.

4. A tire pressure monitoring system comprising:
-
tire pressure detecting means provided to each of tires of a vehicle for detecting a tire pressure;
transmitting means for transmitting radio signals indicative of a detected tire pressure of each tire and each corresponding ID code provided to each tire separately;
receiving means provided to a vehicle body side for receiving the radio signals from the transmitting means;
ID code registration means for registering the ID code of each tire by updating data stored in a memory; and
jack-up determination means for determining whether the vehicle has been jacked up;
wherein the ID registration means performs registration of the ID code of each tire when the jack-up determination means determines that the vehicle has been jacked up.

5. A tire pressure monitoring method comprising:
-
detecting a tire pressure of each of tires of a vehicle;
transmitting radio signals indicative of a detected tire pressure of each tire and each corresponding ID code provided to each tire separately;
receiving the radio signals;
registering the ID code of each tire by updating data stored in a memory; and
determining whether the vehicle has been jacked up;
wherein the registering of the ID code of each tire is performed when the determining determines that the vehicle has been jacked up. - View Dependent Claims (6, 7)
detecting a vehicle speed; and
detecting a vehicle height at each position where each tire is disposed;
wherein the determining includes determining that one of the tires has been changed with the vehicle being jacked up if a condition of a vehicle speed being zero has continued a predetermined time and if a variation of the vehicle height equal to or larger than a predetermined value has occurred before lapse of the predetermined time after stoppage of the vehicle.

7. A tire pressure monitoring method according to claim 6, wherein the registering comprising entering an ID code registration mode if the determining determines that one of the tires has been changed with the vehicle being jacked up and thereafter the vehicle speed becomes higher than a predetermined value.
