Patent ID: 7975410

Claim:
A control system for use with an excavation machine, comprising: a boom member; a linear actuator connected to pivot the boom member in a first direction; a rotary actuator connected to swing the boom member in a second direction substantially orthogonal to the first direction; an operator input device configured to generate a command signal indicative of a desired movement of the boom member; a tilt sensor configured to detect an inclination of the excavation machine; and a controller in communication with the rotary actuator, the operator input device, and the tilt sensor, the controller being configured to: receive a swing end stop for the boom member; control the rotary actuator to move the boom member based on the command signal; and modify the command signal based on the detected inclination in a manner to account for an effect the detected inclination will have on a speed and force of the boom member to inhibit movement of the boom member past the swing end stop.
