Abstract
A method is for operating an axial piston machine whose displacement volume is continuously adjustable using a double-acting control cylinder having two oppositely acting control chambers. The method includes providing a corresponding axial piston machine. An electrically adjustable pressure control valve is connected to one control chamber. Another control chamber is connected to an electrically adjustable 3/2-way switching valve. The method includes providing a target control pressure difference. A zero case is defined as a case in which the target control pressure difference is essentially zero. A positive case is defined as a case in which the target control pressure difference is positive. A negative case is defined as a case in which the target control pressure difference is negative. The method further includes calculating a first and a second control pressure. A case differentiation includes determining whether the zero case, the positive case, or the negative case is present.
