Patent ID: 8132607

Claim:
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.
