Beschreibung
Zusammenfassung:	A method for controlling a hydrostatic transmission (4) of a motor vehicle (1) with a drive axle (3) driven by the hydrostatic transmission (4) includes the steps of detecting an input command emitted by a driver operable command member (9) of the motor vehicle, determining a limit drive torque transmissible to the drive axle (3) as a function of the detected input command through a predetermined mapping, acquiring a first quantity indicative of an actual torque acting on the drive axle (3), computing a desirable speed value for the motor vehicle (1) as a function of a relationship between the limit drive torque and the actual torque indicated by the acquired first quantity, determining a target speed for the motor vehicle (1) based on the computed desirable speed value, and setting the target speed as a set-point for controlling the hydrostatic transmission (4).
