The inflation pressure data

摘要

PROBLEM TO BE SOLVED: To provide a tire pneumatic pressure control system capable of safely regulating the pneumatic pressure of each tire when automatically regulating the pneumatic pressure to the pressure suitable for the traveling environment whether a traveling road is a general road or a highway while a vehicle is traveling.;SOLUTION: The data for setting the tire pneumatic pressure according to at least the kind of a road is stored in a tire pneumatic pressure data storage unit 35, the kind of the traveling road by the data taken in from a navigation device 12 is detected by a traveling road kind detection unit 50, and the tire pneumatic pressure is determined by a tire pneumatic pressure determination unit 31 by the data of the tire pneumatic pressure data storage unit 35 corresponding to the detected road kind. When the stable condition of the vehicle traveling is detected by a traveling stability detection unit 39, a tire pneumatic pressure changing unit 40 changes the tire pneumatic pressure of front wheels 42 and rear wheels 43 to the pneumatic pressure determined by the tire pneumatic pressure determination unit 31 through a decrease 45 in pressure or an increase 46 in pressure.;COPYRIGHT: (C)2006,JPO&NCIPI
