This disclosure concerns a snow groomer vehicle and a method for controlling a snow groomer vehicle. In addition, this disclosure concerns a management system for a snow groomer vehicle, a ski resort comprising this management system, and a method for managing a ski resort.
A snow groomer vehicle is used by professional operators who are instructed in the use of a snow groomer vehicle. Usually, the snow groomer vehicles are used at night because the ski slopes are free and not occupied by users. In addition, the snow groomer vehicles operate on snowy slopes where obstacles and sources of danger cannot be immediately recognised due to the presence of snow throughout the surrounding environment. In addition, a snow groomer vehicle may be used by expert operators and less expert ones who do not know the environment in which they are operating, and the associated risks, perfectly.
For this reason, the use of a snow groomer vehicle may entail risks for the operator, for people around the snow groomer vehicle, and for the surrounding environment due to various factors, for example due to there being excessive snow on the slope that makes it more difficult to recognise surrounding obstacles and sources of danger either due to scarce visibility owing to particular weather conditions, or due to the operator's scarce knowledge of a particular place where they are operating, for example, a particular slope on which they are operating, or due to the inexperience of an operator, perhaps an operator who does not have a great deal of experience in the use of snow groomer vehicles in general or of the particular snow groomer vehicle that they are operating.
The purpose of this disclosure is to provide a snow groomer vehicle that reduces certain of the drawbacks of certain of the prior art.
According to this disclosure, therefore, a snow groom vehicle comprising the following is provided: a frame; two tracks; a drive unit connected to the two tracks to move the snow groomer vehicle; at least one working device selected from a group of working devices including: a winch, a tiller assembly, and a shovel, in particular the working device being connected to the frame by a connecting device; at least one control device configured to control at least one parameter of the snow groomer vehicle, such as related to the tracks or the at least one working device, in particular the at least one parameter being selected from a group comprising the following parameters: speed of the snow groomer vehicle; number of revolutions of the drive unit; switching on of a light assembly of the snow groomer vehicle; settings of the tiller; settings of the winch; settings of the blade; positions of the blade with respect to the three Cartesian axes; settings of the snow groomer vehicle; setting of the suspension of the snow groomer vehicle; a message to be sent to a display screen of the snow groomer vehicle; setting of the speed limit; setting of alarms; warnings concerning driving direction, in particular warnings concerning critical area entry; warning of risk of collision with static or dynamic objects; distance indicator to other snow groomer vehicles such as during operations of fleet snow groomer vehicles; direction of rotation of a shaft of the tiller assembly; depth and/or angle of cut of the tiller assembly, such as of the tiller; position of the tiller assembly along a vertical axis; mode of adjusting the position of the tiller assembly along a vertical axis, in certain instances, from among; a mode in which the tiller assembly is in a fixed position, a mode in which the tiller assembly exerts a given pressure on the snowpack in addition to its own weight or subtracted from its own weight and said exerted pressure value, and a mode in which the tiller assembly is in a floating position, in particular, in the floating position, it follows the snowpack; position of the wings, open or closed; volume of a working chamber of the tiller; position of the tiller with respect to a horizontal plane; mode of adjusting the position of the tiller with respect to a horizontal plane preferably between a mode in which the tiller assembly is in a fixed position, and a mode in which the tiller assembly is in a floating position, in particular, in the floating position, it follows the movements of the snow groomer vehicle; and position of the finisher; the snow groomer vehicle comprising a radio communication unit coupled to the control device and configured to receive data from the outside and preferably send data to the outside, and configured to provide the data received from the outside to the control device; the snow groomer vehicle comprising a user interface comprising at least one control for receiving control instructions from an operator relating to the at least one parameter of the snow groomer vehicle and coupled to the control device so as to send thereto the control instructions received from the operator; the snow groomer vehicle comprising a position detector, in particular of the GNSS type, configured to detect the position preferably within a ski resort and coupled to the control device so as to send the detected position to the control device; the control device being configured to control in a first operating mode the at least one parameter based on the operator's control instructions received via the user interface, on the data received via the radio communication unit, and on the position detected via the position detector.
In accordance with the present disclosure, the use of the snow groomer vehicle is relatively safer for an operator because it is possible to set parameters for the snow groomer vehicle, for example remotely, so as, for example, to limit the speed in some areas that are particularly relatively dangerous, or to switch on the lights or to implement various functions to improve the relative safety of the snow groomer vehicle when the snow groomer enters some areas that are defined beforehand as relatively dangerous.
Another purpose of this disclosure is to provide a method of controlling a snow groomer vehicle that reduces certain of the drawbacks of certain of the prior art.
