DRIVE SYSTEMS AND METHODS FOR IMPLEMENTING ENGINE STALL PROTECTION IN A SELF-PROPELLED MACHINE

摘要

Drive systems and methods for implementing engine stall protection in a self-propelled machine are disclosed. A drive system (100) of a self-propelled machine incorporating engine stall protection includes an engine (110) being in communication with a control unit (150) and transmitting power and an engine load signal to the control unit. An actuation mechanism can be actuated to assign a desired ground speed of the self-propelled machine, the actuation mechanism being in communication with the control unit and transmitting a control signal corresponding to the desired ground speed to the control unit. The control unit is configured to control a transmission motor (132) to achieve an actual ground speed of the self-propelled machine based on both the engine load signal and the control signal. The engine load signal can be an engine speed signal, wherein engine speed is dependent on a load applied to the engine.
