  • Control apparatus and method for a hydrostatically actuated vehicle
    Patent number: 8424630
    Abstract: A method and apparatus for controlling operation of an engine in a hydrostatically driven vehicle having high and economy modes may include monitoring one or more control inputs. When in the economy mode the engine may be operated: at a fixed propel neutral speed when a propel control input is in a neutral position; at a fixed propel drive speed when the propel control input is in a drive position and a propel pump displacement signal is less than a maximum displacement position of a propel pump; and at a variable drive speed when the propel control input is in the drive position and the propel pump displacement signal indicates a maximum displacement position. The economy mode conserves fuel while ensuring that sufficient engine power is maintained to operate the propel and any implement pumps provided on the vehicle.
