PURPOSE:To provide a suspension controller by which a comfortable ride can be obtained, regardless of an undulant road-surface. CONSTITUTION:A control signal adjusting part 44 for sending a control signal thetafor making an extending side damping coefficient small is provided in a control signal sending part 43, when the absolute value of downward sprung acceleration alpha exceeds a sprung acceleration reference value. When a vehicle finishes rise of the undulation on a road-surface and the absolute value of downward sprung acceleration alpha exceeds the sprung acceleration reference value, the control signal adjust part 44 sends the control signal theta for making the extending side damping coefficient small to the control signal sending part 43 and not only a displacement in the extending direction of an damping coefficient valuable type shock absorber but also the displacement in the relative extending direction of a wheel and a car body is carried out easily and the downward vertical acceleration of the car body is restrained to a small value. Thereby, such feeling as being thrown out upward as well as uncomfortable feeling are not given to an occupant. |
