A method for controlling a hydrostatic drive, which has a driving engine, a hydraulic pump coupled to the driving engine and a hydraulic motor coupled to the hydraulic pump by way of a pressurized hydraulic work line, includes calculating a manipulated variable vector comprising at least one manipulated variable for the hydrostatic drive based on (i) an output torque setpoint value for a torque on a secondary shaft driven by the hydraulic motor, (ii) a rotational speed and torque of the driving engine emerging from a predetermined operating point characteristic for the driving engine, and (iii) volumetric and mechanical losses of at least one adjuster unit comprising the hydraulic pump and the hydraulic motor. The manipulated variable vector is used to control the hydrostatic drive.
