TIRE PRESSURE CONTROL SYSTEM, TIRE PRESSURE CONTROL DEVICE AND TIRE PRESSURE CONTROL METHOD
First Claim
1. A tire pressure control system that controls a tire pressure at each wheel of a vehicle, comprising:
- a wheel side pressure sensor, installed at each wheel, that detects the tire pressure;
a transmitter, installed at each wheel, that wirelessly transmits tire pressure information that indicates the detected tire pressure;
a receiver, installed at a vehicle body, that receives the tire pressure information transmitted by the transmitter;
a tire pressure regulating device, installed at the vehicle body, that regulates the tire pressure by supplying and discharging air to and from the tire; and
a control unit that controls the tire pressure to a target value by driving the tire pressure regulating device based on the tire pressure information received by the receiver,wherein the control unit drives the tire pressure regulating device regardless of whether the tire pressure information is received if a reception-incapable condition, in which the receiver is unable to receive the tire pressure information, occurs.

Abstract
A tire pressure control system that controls the tire pressure in the tire at each wheel of a vehicle includes: a wheel-side tire pressure sensor; a transmitter that transmits the detected tire pressure; a receiver that receives the tire pressure information from the transmitter; a tire pressure regulating device; and a control unit that drives the tire pressure regulating device based on the tire pressure information. The control unit drives the tire pressure regulating device regardless of whether the tire pressure information is received if a reception-incapable condition, in which the receiver is unable to receive the tire pressure information, has occurred.

11. A tire pressure control device, installed in a vehicle, that controls a tire pressure at each wheel of a vehicle, wherein the vehicle includes:
- a wheel-side pressure sensor, installed at each wheel, that detects the tire pressure thereof;
a transmitter, installed at each wheel, that wirelessly transmits of tire pressure information indicating the tire pressure; and
tire pressure regulating device, installed on the vehicle body, that regulates the tire pressure by supplying and discharging air to and from the tire, wherein;the tire pressure control device outputs, to the tire pressure regulating device, a control signal to adjust the tire pressure to a target value based on the tire pressure information transmitted from the transmitter; and the tire pressure control device outputs a control signal to drive the tire pressure regulating device regardless of whether the tire pressure information is received, if it is determined that a reception-incapable condition, in which the receiver cannot receive the tire pressure information, has occurred.
- a wheel-side pressure sensor, installed at each wheel, that detects the tire pressure thereof;
-
12. A tire pressure control method of a tire at each wheel of a vehicle, comprising:
-
detecting the tire pressure by using a wheel side pressure sensor installed at each wheel; wirelessly transmitting tire pressure information that indicates the detected tire pressure from a transmitter installed at each wheel; receiving the transmitted tire pressure information by a vehicle body-side receiver; and controlling the tire pressure to a target value based on the transmitted tire pressure information, wherein if a reception-incapable condition, in which the tire pressure information cannot be received by the vehicle body-side receiver, occurs, the tire pressure is adjusted regardless of whether the transmitted tire pressure information is received. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A tire pressure control system that controls a tire pressure at each wheel of a vehicle, comprising:
-
a sensor that detects a wheel state of each wheel; a tire pressure regulating device that regulates the tire pressure by supplying and discharging air to and from the tire; and a control unit that controls the tire pressure to a target value by driving the tire pressure regulating device based on the detected wheel state, and that drives the tire pressure regulating device regardless of whether the wheel state has been obtained if a predetermined obtainment-incapable condition, in which the wheel state cannot be obtained, occurs.
