Abstract
An apparatus and method for controlling a variable displacement motor of a hydrostatic transmission is provided. The apparatus includes an engine, and a hydraulic pump mechanically coupled to the engine. The variable hydraulic motor includes an output shaft. The apparatus monitors rotational speed of the output shaft. The apparatus and method control motor displacement and detect and/or predict the occurrence of an overspeed condition. The displacement of the motor is modified if an overspeed condition is predicted and/or detected.
