Abstract
A method for managing power in a hydrostatically driven vehicle includes calculating the power consumption of the vehicle based on the pressure of the compressed fluid in a hydraulic circuit, and the displacement of the pump. An electronic controller further calculates the power output of the engine based on at least one engine operating parameter, and operates to change the power output of the engine based on a difference between the power consumption and the power output.
