<P>PROBLEM TO BE SOLVED: To provide a method and a device that can obtain the roll angle at automatic vehicle height adjustment non-execution time by desired accuracy only by detecting displacement and an internal pressure value of a suspension at one arbitrary time point. <P>SOLUTION: The roll stiffness coefficient K<SB POS="POST">ϕ13</SB>that is intrinsic to a vehicle is calculated from a first and second displacement and a first and second inner pressure value that are measured. The roll angle ϕ<SB POS="POST">2es</SB>when automatic vehicle height adjustment is not executed is obtained on the basis of the displacement and inner pressure value measured at an arbitrary time point after calculating and the calculated roll stiffness coefficient K<SB POS="POST">ϕ13</SB>(K<SB POS="POST">ϕ13new</SB>). <P>COPYRIGHT: (C)2013,JPO&INPIT |
