Work vehicle with improved implement position control and self-leveling functionality

A method for automatically adjusting the position of an implement for a work vehicle may generally include receiving an input associated with a flow-related parameter of the work vehicle as loader arms of the work vehicle are being moved and determining a speed control signal for the implement based at least in part on the flow-related parameter, wherein the speed control signal is associated with an implement speed at which the implement is to be moved in order to maintain the implement at a fixed orientation relative to a given reference point. In addition, the method may include generating a valve command signal based at least in part on the speed control signal and transmitting the valve command signal to a valve associated with the implement in order to maintain the implement at the fixed orientation as the loader arms are being moved.
