The invention provides a suspension control apparatus for a vehicle which
can execute a suspension control suitable even for a rough road by
executing the suspension control based on an actual road surface profile,
while taking various vehicle states (weight, speed, etc.) into
consideration, and learning the road surface profile. The suspension
control apparatus has a vertical acceleration sensor for detecting a
vertical acceleration of the vehicle, and a control unit for determining
a road surface profile by estimating waves and irregularities in the road
surface based on the vertical acceleration of the vehicle detected by the
vertical acceleration sensor, and determining a suspension control value
based on the thus determined road surface profile.
