1. A method for controlling a snow-trail grooming vehicle, comprising the steps of:
- providing a snow-trail grooming vehicle having a drive motor for providing driving power, a chain or track drive, a hydraulic pump driven by the drive motor and a hydrostatic gear of the chain or track drive, further consumers of driving power comprising at least one of a snow-trail grooming device and a cable winch, means for distributing driving power onto the chain or track drive and the snow-trail grooming device and cable winch, and a central processing system for controlling said means for distributing driving power;
selectively prioritizing one of the chain or track drive, the snow-trail grooming device and the cable winch;
correlating the adjustments of the drive motor, the hydraulic pump driven by the drive motor and the hydrostatic gear of the chain or track drive under the control of the central processing system in order to obtain the desired distribution of the driving power with little power loss; and
distributing the driving power according to the desired distribution.
