CONSTRUCTION MACHINE RIDE CONTROL SYSTEMS AND METHODS USING ELEVATION CYLINDER CONTROL

A road work machine comprises a frame, a plurality of ground engaging units, a plurality of vertically moveable legs connecting the plurality of ground engaging units to the frame, respectively, a hydraulic system to control heights of the plurality of vertically moveable legs, pressure sensors for sensing hydraulic pressures in the plurality of vertically movable legs, and a controller configured to, in response to signals received from the pressure sensors, generate a control signal. A method for ride control can comprise adjusting an attitude of the machine in response to sensed pressures.
