Abstract: 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.

at least one satellite navigation device and/or a second detection device; wherein the second detection device is configured to define data by processing the areas of the environment in front of the snow groomer vehicle and framed by said device;
a control system including a processing unit configured to process the data from the satellite navigation device and/or from at least the second detection device and to define an objective map of a desired snow treatment;
the processing unit being configured to define at least one first desired implement configuration defined on the basis of an objective map in such a way that the passage of the implement causes the snowpack to change according to a desired conformation;
the processing unit being configured to determine a second optimal implement configuration on the basis of the first desired implement configuration and on the basis of the defined snow quality value; and
the processing unit being configured to perform at least one of the following two actions:
sending to a display screen the information of the optimal implement configuration in order to suggest to the operator how to act on the implement;
operate the actuator assembly and/or the speed of rotation of the implement and/or the working chamber of the implement so as to make the implement work in the second, determined optimal configuration.
