A method for controlling a rotation damper operating according to the gyroscopic principle for a motor vehicle, wherein the rotation damper includes a flywheel, which is driven by a drive and rotating about a rotation axis with an angular velocity .sub., which is cardanically mounted via a first bearing element and via a second bearing element, wherein the flywheel is rotatably mounted on a first bearing element and at a rotation angle , and the first bearing element is rotatably mounted on a second bearing means about a first axis that is oriented orthogonally to the rotation axis of the flywheel, and the second bearing element is rotatably mounted at a second rotational angle ().

One or more vehicle sensors can be used in a suspension control system of an agricultural machine to dynamically adjust pistons located proximal to wheels of the machine to substantially control orientation. Such vehicle sensors could include: a speed sensor configured to provide an output indicating a speed of the machine; a turn angle sensor configured to provide an output indicating a turn angle of the machine; and/or an Inertial Measurement Unit (IMU) configured to detect a chassis-to-horizon angle. The output can be compared to a threshold for determining when to control valves in the suspension system to apply height corrections.

A damper control device feeds back a pressure within an extension-side chamber to control an extension-side solenoid valve that adjusts the pressure within the extension-side chamber, and feeds back a pressure within a compression-side chamber to control a compression-side solenoid valve that adjusts the pressure within the compression-side chamber. The damper control device performs a compression-side reduction correction which reduces a compression-side current supplied to the compression-side solenoid valve during extension of a damper, and performs an extension-side reduction correction which reduces an extension-side current supplied to the extension-side solenoid valve during contraction of the damper.

A suspension for a motor vehicle is described comprising a first lever directly or indirectly connected to a sprung mass and to an unsprung mass of said motor vehicle; and a shock absorber comprising a first element connected to the sprung mass and a second element connected to the unsprung mass movable relative to one another; the shock absorber comprises, in turn, a driving member, which can operatively be operated so as to determine the motion of the first element relative to the second element; and a transmission assembly designed to transmit the motion from said driving member to the first element; the suspension comprises a second lever defining a housing at least partly accommodating the transmission assembly; the second lever is articulated on said first lever and is directly or indirectly connected to the sprung mass and unsprung mass.

A method for changing a ride height position of a motor vehicle comprises measuring a respective relative distance of a vehicle superstructure from corresponding wheels, with spring travel sensors and transmitting a respective spring travel signal to an electronic open-loop and closed-loop control device of the motor vehicle. The spring travel signals pass through a frequency filtering in the electronic open-loop and closed-loop control device The frequency filtering initially comprising a bandpass filtering which splits the spring travel signal into a signal component excited by the wheel and a signal component excited by the vehicle superstructure. The signal component excited by the vehicle superstructure is filtered out, the frequency filtering then comprising an absolute value conversion of the bandpass-filtered spring travel signal and subsequently a low-pass filtering.

A damper control device feeds back a pressure within an extension-side chamber to control an extension-side solenoid valve that adjusts the pressure within the extension-side chamber, and feeds back a pressure within a compression-side chamber to control a compression-side solenoid valve that adjusts the pressure within the compression-side chamber. The damper control device performs a compression-side reduction correction which reduces a compression-side current supplied to the compression-side solenoid valve during extension of a damper, and performs an extension-side reduction correction which reduces an extension-side current supplied to the extension-side solenoid valve during contraction of the damper.
