<P>PROBLEM TO BE SOLVED: To provide a method and a device that can obtain with high accuracy the roll angle at automatic vehicle height adjustment non-execution time without depending on the change state of the suspension and the state change of a load. <P>SOLUTION: In a first method, the roll angle ϕ<SB POS="POST">2es</SB>when vehicle height adjustment is not executed is obtained by using the displacements and the inner pressure values (a first and second displacement and a first and second inner pressure value) at two different points in time. In a second method, the roll angle ϕ<SB POS="POST">2es</SB>when vehicle height adjustment is not executed is obtained by using the displacement and inner pressure value (second displacement and second inner pressure value) at one point in time and a predetermined roll stiffness coefficient K<SB POS="POST">ϕ13new</SB>stored before measuring the displacement and the inner pressure value. The first method and the second method are selected and employed, as appropriate, according to the transitory condition of the suspension or the changes in the state of a load. <P>COPYRIGHT: (C)2013,JPO&INPIT |
