Piste grooming vehicle

A piste grooming vehicle comprising:

• at least one piste grooming device for preparing a piste;
• a detection device configured to detect an actual topography of a piste section, positioned in front of the piste grooming vehicle in a forward travel direction thereof, of the piste, the detection device being configured to:
• detect coordinates of the actual topography with respect to a local vehicle coordinate system assigned to the piste grooming vehicle;
• and detect a location and a position of the piste grooming vehicle and therefore of the local vehicle coordinate system with respect to a global reference coordinate system, the detection device comprising:
• a GPS unit configured to detect the location of the piste grooming vehicle with respect to the global reference coordinate system;
• and
• a position measuring unit configured to detect the position of the piste grooming vehicle with respect to the global reference coordinate system by measuring a longitudinal inclination and/or a transverse inclination of the piste grooming vehicle;
• a determining device connected to the detection device and configured to transform the detected coordinates of the actual topography into the global reference coordinate system in accordance with the detected location and the detected position of the local vehicle coordinate system, the determining device being further configured to determine at least one differential value between the transformed coordinates of the actual topography and coordinates of a reference topography of the piste, the coordinates of the reference topography being based on the global reference coordinate system, to determine an actual topography of the piste section with respect to the global reference coordinate system;
• and
• a control device connected to the determining device and configured to actuate the at least one piste grooming device in accordance with the at least one determined differential value.
