Method for controlling a hydrostatic drive

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, the method comprising:

• 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, the secondary shaft rotating at a secondary shaft rotational speed, (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;
• and
• using the calculated manipulated variable vector to control the hydrostatic drive.
