<p><P>PROBLEM TO BE SOLVED: To provide an air pressure control device of a tire which eliminates deflection of a vehicle by generating rotational moment in the direction of eliminating the deflection of the vehicle around the center of gravity of the vehicle through a changing ratio of air pressure of left and right tires due to change in air pressure of each tire. <P>SOLUTION: The air pressure control device 20 of the tire estimates a target yaw rateγ<SB>0</SB>from a vehicle speed V and a steering angleθ, acquire a plurality of data D(n) to be difference between the target yaw rateγ<SB>0</SB>and a real yaw rateγ, acquires an average value Dave from the plurality of the acquired data D (n), and estimates the deflection direction and amount of deflection of the vehicle based on the acquired average value Dave. The air pressure control device 20 of the tire generates the rotational moment M in the direction of eliminating the deflection of the vehicle around the center of gravity of the vehicle by changing the air pressure of the tire in accordance with the average value Dave. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
