CA 2396321

A combine with a throughput dependent speed control includes an angle sensor responsive to uphill, downhill and sidehill slopes. When the combine is angled from a level position, harvest speed is lowered to prevent grain losses from increasing above a target level. The control continuously learns tilt angle, loss and throughput correlation, and the speed reduction is selected based upon the learned correlation. In the preferred embodiment, throughput is estimated utilizing rotor variable drive actuator pressure (RVDAP), and a target RVDAP is modified for short periods of time in accordance with the learned correlation.
