Arrangement for the control of the forward propulsion speed of a harvesting machine with fuzzy logic

Abstract
A crop harvesting machine is equipped with a crop intake arrangement which delivers crop to a crop processing arrangement. In order to maintain a substantially constant flow of crop to the crop processing arrangement despite a variance in the amount of crop located in various locations on a field, a control circuit employing non-precise or fuzzy logic controls the forward propulsion speed of the harvesting machine and/or the speed of a conveyor used to unload a buffer or crop accumulator that is mounted upstream from the crop processing arrangement. This control is based on crop flow data obtained by a sensor that senses the rate and/or the amount of a crop taken up by the crop intake arrangement, and by a fill sensor associated with a buffer which temporarily accumulates crop at a location upstream from the crop processing arrangement.
