Abstract: A system for communicating an impact sustained by a work machine moving at a worksite to a remote operator workstation for controlling the work machine through the remote operator workstation. The system includes a controller configured to obtain data associated with an acceleration of the work machine along one or more degrees of motion during a movement of the work machine at the worksite and derive an acceleration value based on the data. The controller is further configured to issue a notification of the impact of the work machine to the remote operator workstation through an output device of the remote operator workstation if the acceleration value exceeds a threshold acceleration value during the movement of the work machine.

Abstract: A control system for a machine includes a chassis, an implement attached to the chassis, at least one sensor coupled to the chassis or the implement, and a controller in communication with the sensor. The controller is configured to receive one or more signals from the at least one sensor, determine a stabilization factor based on the one or more signals from the at least one sensor, and signal one or more actuators to control a movement and/or a position of the implement based at least in part on the stabilization factor.

Abstract: Flushing circuits for closed loop hydrostatic circuits enable overriding of the normal function of the flushing circuit during certain machine operational events where flushing can cause undesirable performance issues. The disclosed flushing circuits may prevent flow from leaving the flush valve, may prevent flow from leaving the flushing circuit, may prevent flow from entering the flushing circuit, may prevent the flush valve from shifting from a normally closed position to an open position or may replace the hydro-mechanical control of the flush valve with an electronic control. Cancellation of the flushing function may be commanded by a controller based on fluid temperatures, pressures, turning commands, engine speed, etc.

Abstract: A track type tractor incorporates control over lift, tilt, angle and pitch into an implement control joystick. The pitch cylinder and the tilt cylinder share segments of the hydraulic circuit, and a diverter valve prioritizes pitch control over tilt control in the rare occurrence when the operator is requesting both tilt and pitch changes to the dozer blade. Angle control and pitch control may be accomplished by finger controllers incorporated into the implement control joystick. Thus, the operator can control the dozer blade in four degrees of freedom without losing contact with the implement control joystick.
