TIRE PRESSURE CONTROL SYSTEM, TIRE PRESSURE CONTROL DEVICE AND TIRE PRESSURE CONTROL METHOD

摘要

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.
