Abstract
A method for filling a hydraulic system with a hydraulic fluid includes sealing the hydraulic system in a pressure-tight manner and recording a pressure in the sealed hydraulic system, filling or removing a predefined volume of the hydraulic fluid from the sealed hydraulic system, recording a pressure in the sealed hydraulic system after the filling or removing, calculating a volume of a total residual air in the hydraulic system depending on the pressures before and after the filling or removal of the predefined volume, calculating a final correction volume depending on the volume and a design-specified air feed of the hydraulic system, and refilling or removing the calculated final correction volume to achieve a final correct filling quantity for the hydraulic system.
