Beschreibung
Zusammenfassung:	Described herein are control systems and methods for self-propelled windrowers and other types of agricultural dual-path machines that improve drive efficiency of the machines through automated control of propulsion, steering, or engine speed. In some embodiments, a control system improves drive efficiency by adjusting engine speed and pressure and flow of a hydraulic propulsion system. In such embodiments and others, a controller controls the engine speed and pressure and flow of the hydraulic propulsion system in left and right drive pumps and motors of the dual-path machine according to setpoints and adjustment factors. The adjustment factors in such examples and others are not allowed to exceed respective thresholds, such as a fixed percentage of a raw command, to prohibit immobilizing the machine while disabling or limiting the controller. The adjustment factors are based on feedback signals from various sensors of the machine.
