Pneumatic fluid is discharged from or supplied to the pneumatic compartment of a hydropneumatic vehicle suspension depending on the sign of the difference between the vehicle speed and the reciprocal square root of the relative displacement between the suspension elements being positive or negative, so that the stiffness of the suspension is increased and reduced with increasing and decreasing speed of the vehicle. Alternatively, in a vehicle having purely hydraulic suspensions, transverse acceleration due to curves is sensed and used to vary the amount of hydraulic fluid in the suspensions associated with individual wheels so as to vary the attitude of the sprung mass of the vehicle in order to compensate for the transverse inertial forces acting on the passengers. Transient vertical forces acting on the wheels due to unevenness of the driving surface are also used to vary the amount of fluid in the suspension so as to simulate the action of springs.
