Patent number: 12320085Abstract: A snow groomer vehicle includes a frame, a tool connected to the frame through a front connecting device equipped with an actuator assembly operable to determine a relative position of the tool with respect to the frame, a satellite navigation device and a control system. The control system includes a processing unit and a memory device, containing a target map representing a desired surface to be obtained by processing the snowpack over a region. The processing unit determines a position and orientation of the frame from the data provided with satellite navigation device and determines a configuration of the tool as a function of the position and orientation of the frame and of the target map, so that the passage of the tool causes a removal of the snowpack that conforms the snowpack to the target map. The actuator assembly is operated so as to bring the tool into the determined configuration.Type: GrantFiled: May 3, 2019Date of Patent: June 3, 2025Assignee: PRINOTH S.P.A.Inventors: Martin Kirchmair, Alberto Paoletti, Richard Casartelli
