The present invention relates to a method for controlling a hydrostatic travel drive (1) of a mobile working machine, wherein the hydrostatic travel drive is provided with a first hydraulic machine (4) with adjustable displacement volume and with a second hydraulic machine (6) and a third hydraulic machine (8), wherein the first hydraulic machine can be coupled or is coupled to a drive machine (20), wherein the pressure medium coming from the first hydraulic machine can be conveyed to the second and to the third hydraulic machine (6, 8), which are arranged parallel to each other, the second hydraulic machine (6) being rotatably connectable by means of a clutch (38) to at least one wheel or chain or axle to be driven, the third hydraulic machine (8) being rotatably connected to the at least one wheel or chain or axle, wherein the displacement volume of said first hydraulic machine (4) can be regulated based on a control pressure,
characterized in that the method comprises the following steps:
a. Receiving a driving demand for the mobile working machine;
b. Providing a request for the opening of the clutch so that the second hydraulic machine (6) will not be anymore rotationally connected to the at least one wheel or chain or axle;
c. Reducing the displacement volume of said first hydraulic machine (4) by reducing said control pressure to an unload level which is dependent on the driving demand;
d. Opening said clutch;
e. Increasing the displacement of said first hydraulic machine (4) by increasing said control pressure to a load level which is dependent on said driving demand.
