ABSTRACT:
An improved method for controlling a suspension apparatus for a vehicle which is capable of enhancing a boarding-on feeling and a running stability by increasing a boarding-on feeling and the road surface contact force of wheels based on the size of a road surface input and a control logic which is variable in accordance with a frequency. The method includes the steps of obtaining a displacement value by passing an acceleration value measured by a vehicle vertical acceleration sensor through an integration unit having the following Equation (1); and computing a predetermined road surface signal by using the acceleration and displacement value as shown in Equation (2); ##EQU1## where, .xi..sub.1 and w.sub.1 are coefficients used for determining the coefficient of the filter used in the integration.
