Abstract
The present invention relates to a method for determining a present state of wear of a hydrostatic machine during the operation of the hydrostatic machine. The hydrostatic machine comprises a drive with variable rotational speed and a hydrostatic pump, wherein the drive is designed to drive the hydrostatic pump for generating a volume flow of a fluid, and wherein the hydrostatic machine is connected to a fluid transport channel in which the fluid is transported in a manner driven by the hydrostatic machine. The method has a step for determining a first torque of the drive at a specified drive vector. Furthermore, the method has a step for ascertaining a second torque of the drive at the specified drive vector using a first calculation method, and in addition, the method has a step for determining the present state of wear of the hydrostatic machine using a second calculation method, in order to compare the first determined torque and the second ascertained torque to one another.
