SYSTEM AND METHOD FOR ADJUSTING BALANCE OF OPERATION OF HYDRAULIC AND ELECTRIC ACTUATORS
First Claim
1. A system for controlling power in a machine comprising an electric power source, a hydraulic power source, an electric actuator, and a hydraulic actuator, the system comprising:
- an interface; and
a controller configured to;
receive a signal indicative of a requested hydraulic operation of the hydraulic actuator, the requested hydraulic operation corresponding to a requested hydraulic power level;
receive a signal indicative of a requested electric operation of the electric actuator, the requested electric operation corresponding to a requested electric power level;
provide a signal for supplying an amount of electric power to the electric actuator at a level less than the requested electric power level based on an electric power output ratio; and
provide a signal for supplying an amount of hydraulic power to the hydraulic actuator at a level less than the requested hydraulic power level based on a hydraulic power output ratio,wherein at least one of the electric power output ratio and the hydraulic power output ratio is adjustable via the interface.

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.
