  • Patent number: 9416779
    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.

  • Patent number: 9067501
    Abstract: A system for controlling power in a machine includes an interface and a controller configured to receive a signal indicative of a requested hydraulic operation of a hydraulic actuator corresponding to a requested hydraulic power level. The controller is further configured to receive a signal indicative of a requested electric operation of the electric actuator corresponding to a requested electric power level. The controller is also configured to provide a signal for supplying electric power to the electric actuator less than the requested electric power level based on an electric power output ratio, and provide a signal for supplying hydraulic power to the hydraulic actuator less than the requested hydraulic power level based on a hydraulic power output ratio. At least one of the electric power output ratio and the hydraulic power output ratio is adjustable via the interface.
