Abstract
An automatic loading control system for loading a work implement of a work machine with material from a pile may include a lift sensor configured to monitor a lift actuator and communicate a lift signal. The system may also include a tilt sensor configured to monitor a tilt actuator and communicate a tilt signal. A speed sensor may be configured to communicate a speed signal indicative of a speed of the work machine. A control module may be configured to receive the lift signal, the tilt signal, and the speed signal and generate a signal to control a rim-pull based on at least one of a lift velocity of the lift actuator, a tilt velocity of the tilt actuator, and a work machine velocity to facilitate movement of the work implement through the pile.
