Abstract: A vehicular height controlling arrangement changing a length of a suspension cylinder by supplying or draining the hydraulic oil through a damping force selector valve. The damping force selector valve changes a damping force of a suspension cylinder by changing an orifice therein. When the vehicular height is lowered under a vehicle stopping condition, a large orifice is selected in the damping force selector valve so as to quickly lower the vehicular height. Thereafter, a small orifice is immediately selected to suppress the swinging of the automotive vehicle.

Abstract: The posture of a vehicle is controlled using a specific variable damping force damper without the necessity of changing over the variable damping force damper frequently and at a high rate and without using a vehicle height sensor. A variable damping force damper U having at least two change-over modes including a mode in which the compression side damping force is soft when the extension side damping force is hard and another mode in which the compression side damping force is hard when the extension side damping force is soft is interposed between a vehicle body D and a wheel E. The variable damping force damper U is changed over by means of an acceleration sensor J mounted on the vehicle body D and a controller M including an integrator P for converting a signal from the acceleration sensor J into a velocity signal and a calculation processing circuit Q for outputting a changing over signal to the variable damping force damper U in accordance with the velocity signal from the integrator P.
