Patent ID: 8594896

Claim:
A system for automatically controlling movement of a lift arm of a loader near a limit of travel of the lift arm, the system comprising: a sensor on one of the lift arm and the loader; a sensor trigger on another of the lift arm and the loader; and a controller configured to: receive an engine speed signal indicative of an engine speed of an engine on the loader; receive an operator interface actuation signal indicative of an actuation of an operator interface on the loader, the operator interface actuation signal indicating a desired movement of the lift arm; receive a sensor actuation signal indicative of actuation of the sensor based upon movement of the sensor near the sensor trigger at a position near the limit of travel of the lift arm; determine a lift arm command signal for directing movement of the lift arm based at least upon the engine speed signal and receipt of the sensor actuation signal; and transmit the lift arm command signal to an electro-hydraulic system to control the movement of the lift arm.
