ABSTRACT:
A system and process for controlling an excavation implement during excavation between an above-ground position and a below-ground position. The excavation implement is actuated by use of the engine operating at a target output level. A computer controls the rate at which the excavation implement is moved in a generally vertical direction while excavating earth between the above-ground and below-ground positions. A sensor senses a performance parameter indicative of either engine performance or excavation implement performance as the excavation implement progresses through the earth. The computer modifies actuation of the excavation implement in response to the sensed performance parameter to maintain the engine at the target output level when the engine is subject to variations in loading as the excavation implement moves between the above-ground and below-ground positions.
