This disclosure relates to a control system for a machine implement. The control system includes a measurement sensor configured to provide an implement measurement signal indicative of a velocity of a machine implement, and a controller. The controller is configured to provide an implement measurement signal and an operator command signal, and to determine an adjusted implement command based signal based on the implement measurement signal and the operator command signal.

Implement control system for a machine

This disclosure relates to a control system for a machine. The control system includes a sensor configured to provide an implement measurement signal indicative of a velocity of a machine implement, and a controller. The controller is configured to receive the implement measurement signal, determine whether a main threshold condition is met, and to determine an adjusted implement command based at least in part on the implement measurement signal.

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.

A method and apparatus for operating an implement for a machine is provided. The machine has a body, a pump, an implement, an operator station, a first operator input device, and a second operator input device. The pump is mounted to the body and has a first operating range. The implement is mounted to the body and coupled to the pump. The operator station is positioned on the body. The first operator input device is located within the operator station and operable to control the implement over the first operating range and the second operator input device is positioned external to the operator station and operable to control the implement over a second operating range. The second operating range is less than the first operating range.

A protection system is provided for a work machine with a power source. At least one sensor is configured to monitor a fluid parameter of a work machine system external to the power source. The sensor is further configured to produce a signal indicative of a value of the fluid parameter. The component protection system has a control module in communication with the at least one sensor, the control module being configured to derate a power source output base upon the value of the fluid parameter.

When operating a work machine such as a backhoe, fuel consumption, pollution and noise can be decreased by reducing engine speed below a throttle setting when a set of equipment attached to a rear side of a work machine body is idled for a predetermined period of time. The engine speed is reduced by a control system including an electronic control module having an engine speed reduction algorithm. When the electronic control module determines that a seat assembly that is rotatably mounted to the work machine body is in a forward-facing position, the engine speed reduction algorithm is inactive. When the electronic control module determines that the seat assembly in a rearward-facing position, the engine speed reduction algorithm is active. By basing, at least in part, the activation and deactivation of the engine speed reduction algorithm on the seat assembly position, the engine speed reduction algorithm will be active when the backhoe is operable.
