Abstract: A control system for a machine having a cylinder and an accessory is disclosed. The control system may include a pump configured to provide fluid to the cylinder and the accessory, and a controller operatively connected to the pump. The controller may be configured to operate the pump to provide a primary flow to the cylinder at up to a predetermined maximum level for the cylinder. The predetermined maximum level for the cylinder may be less than a maximum flow capability of the pump. The controller may also be configured to operate the pump to provide a secondary flow to the accessory utilizing a remaining fluid.

Abstract: Method of controlling multiple variable displacement hydraulic pumps determined relative to operator commands. If non-second-pump-dominated command, a respective adjusted displacement request is determined based upon the lesser of the operator requested torque limited displacement and an adjusted torque limited displacement that calculated based upon and the torque limited displacement of the respective pump and a scaling factor calculated based upon the first relief valve set pressure and respective pump pressure. If second-pump-dominated command, the set pressure of a relief valve associated with one of the pumps is instead utilized in calculating the scaling factor in the above strategy.

Abstract: A machine may include a continuously variable transmission (CVT) operatively coupled to a power source. A virtual gear ratio may be selected from a plurality of virtual gear ratios associated with the CVT. A power source speed may be locked between a minimum power source limit and a maximum power source limit that are associated with the selected virtual gear ratio. If the virtual gear ratio is changed, a controller including one or more control maps may compare the power source speed as locked to the minimum power source limit and the maximum power source limit as they relate to the newly selected virtual gear ratio. If power source speed is outside the minimum or maximum power source limits, the method may limit the power source speed. In some embodiments, the minimum and/or maximum power source limits may vary with respect to the plurality of virtual gear ratios.

Abstract: A system and method of controlling the speed of a machine having a continuously variable transmission (CVT) operatively coupled to a power source. A plurality of selectable virtual gear ratios can be associated with the CVT. The machine may include an operator input device that may generate a operator input signal indicative of a desired adjustment in the ground speed. The operator input signal may be converted to a CVT speed command and to a power source speed command that are communicated to the CVT and the power source, respectively. The CVT adjusts the machine speed in accordance with the CVT speed command, while the power source adjusts its speed in accordance with the power source speed command, so that operation of the power source is substantially independent of operator of the CVT.

Abstract: A method controls the power-transmission in a machine having a continuously variable transmission (CVT) and a power source operatively coupled together in a powertrain. The method regulates operation of the CVT with a retarding power limit in order to limit the amount of retarding power transferable from the powertrain to the power source. The retarding power may be utilized to decelerate or decrease the speed of the machine. The method may register an operator input signal indicative of a deceleration event from a plurality of possible deceleration events. The deceleration event is compared to a lookup table to determine if the retarding power limit should be adjusted. The method may adjust the retarding power limit in accordance with the comparison.
