Abstract: 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.

Abstract: A method for controlling a machine is provided. The method senses an orientation of a seat of an operator. The method selects a desired mode function with respect to at least one work tool, wherein the at least one work tool is equipped with the machine. Further, the orientation of the seat and the desired mode function is communicated to a processing module. Furthermore, a number of input modules are configured corresponding to predefined patterns to control functions of the at least one work tool and the machine. The predefined patterns define functions of the at least one work tool and the machine corresponding to the orientation of the seat, and the desired mode function.

Abstract: Systems and methods for simulating electro-hydraulic (EH) braking of a work machine using a combination of hydraulic braking and engine braking may include determining a commanded brake pressure requested by an operator, determining an available engine braking force, and comparing the available engine braking force to a maximum available bleed pressure that is available to reduce a hydraulic braking force. An engine braking output and a pressure reducing valve output pressure may be determined based on the available engine braking force and the maximum available bleed pressure. A pressure reducing valve may be actuated so that the hydraulic braking force is equal to the commanded brake pressure minus the pressure reducing valve output pressure, and a transmission may be actuated so that the engine applies an engine braking force equivalent to the engine braking output to brake the work machine.

Abstract: A system for correcting an angle of an implement coupled to a loader is disclosed. The system comprises a controller that is configured to calculate a first angle correction signal based at least upon an engine speed signal and an operator interface actuation signal, the operator interface actuation signal commanding movement of a lift arm on a loader; calculate a second angle correction signal based at least upon a coupler angle signal; transmit the first and second angle correction signals to change the angle of a coupler configured to couple an implement to the lift arm; and temporarily disable transmission of the second angle correction signal.
