Definitions

  • the invention relates to a piste grooming vehicle with a rear implement carrier, on which a piste grooming device is detachably arranged, the Rear implement carrier and / or the slope maintenance device by means of at least the height and / or inclination of an actuator can be changed, and with an electronic control unit that the at least one Control element.
  • Such snow grooming vehicles are for processing snow slopes well known.
  • a known slope grooming vehicle has one Rear equipment carrier on which a piste grooming device is detachably arranged can be.
  • a piste grooming device is for the preparation of Ski slopes especially a snow blower provided with a rear smoothing device, also referred to as a finisher is combined.
  • the rear implement carrier is by means of or several actuating cylinders, in particular hydraulic cylinders, in their position variable.
  • the at least one actuating cylinder is activated using hydraulic control means that are controlled by an electronic Control unit can be controlled.
  • Corresponding control commands are Manually from the driver's cab using the operating and control levers made. In particular in the case of uneven floors, steep slopes, steep slopes or crests, even slope preparation Achieving is a great deal of experience for the driver of the piste grooming vehicle required to operate the control levers.
  • the object of the invention is a piste grooming vehicle of the type mentioned Way of creating that without even greater human experience potential enables uniform slope maintenance.
  • At least one sensor for direct or indirect detection of an actual state of the slope grooming device to be processed slope surface is provided is connected to the control unit and that the control unit one Memory for recording at least one map over different Slope surface designs as well as assigned target settings for height and / or incline of the rear slope grooming device as well as an evaluation unit, which records the actual values of the Compares the sensor with the corresponding target values of the map and depending on the result of the evaluation, the at least one control element controls accordingly.
  • sensors for direct detection of the Slope surface are touching or non-contact sensors provided that directly face the slope surface.
  • Force or displacement sensors are provided, which are located in the area of the rear implement carrier, on the vehicle or in the area of the piste grooming device are arranged.
  • the map for the various slope surface designs and suitable target settings for the respective machining processes is preferably empirically determined by dry settings different processing states achieved.
  • a piste grooming device in Form of a snow blower with a downstream smoothing device are for one a flat slope, the other the transition from a flat Slope on a slope or an incline; furthermore the running over a crest or the situation where a front attachment is lifted out of the snow, which extends the entire slope grooming vehicle due to the weight of the front attachment down in the front area by a small amount lowers and at the same time raises the rear of the vehicle.
  • the milling machine would not have any compensatory control intervention reach too deep into the ground. Uniform slope preparation would not be possible.
  • the respective slope design is recognized and by means of the Control unit an automatic adjustment according to the desired Setting parameters achieved without manual intervention the driver or operator of the snow grooming vehicle is required. Regulation can thus be achieved in a simple manner.
  • the solution is particularly suitable for chain-driven snow grooming vehicles for processing and maintaining snow slopes.
  • Such a piste grooming vehicle can also be used for sand, Gravel, gravel, grass or earth slopes can be used.
  • a control element is on the vehicle side articulated, in particular hydraulic actuating cylinder provided.
  • This Design is particularly advantageous for a chain driven Snow grooming vehicle that is used on snow slopes.
  • actuating cylinder floating in the piste grooming operation, i.e. switched passive, and that Actuating cylinder as a sensor for indirect detection is a force or displacement sensor assigned. Due to the floating entrainment of the actuating cylinder takes place when the slope grooming device or the Rear implement carrier a relative movement between the vehicle side hinged part, i.e. the cylinder part or the piston part, and the part hinged on the rear implement carrier side or snow grooming implement side, correspondingly vice versa of the piston or cylinder part. The relative movement sets a parameter for the corresponding change in position represents, so that a corresponding sensor signal from the electronic Control unit can be processed.
  • the Actuating element as a hydraulic actuating cylinder is preferred controlled by at least one hydraulic control element that is on the electronic control unit is connected.
  • the actuating cylinder is a force sensor assigned as a sensor for indirect detection.
  • a corresponding sensor can be provided, which increases the pressure force or reductions in a hydraulic circuit of the respective Actuating cylinder detected by appropriate displacement movements the rear implement carrier or the piste grooming device.
  • an incline or stationary position sensor in the area of the rear implement carrier or the piste grooming device or directly stationary on the vehicle to arrange.
  • a piste grooming vehicle 1 according to FIGS. 1 and 2 is on the opposite Each side with a crawler track 3 so that the slope grooming vehicle 1 is chain-driven.
  • the slope grooming vehicle 1 is particularly suitable for snow slopes.
  • a rear implement carrier 4 is arranged on which a rear slope grooming device 5 is articulated.
  • the piste grooming device 5 is shown Embodiment of a snow blower 6 and a downstream Smoothing device 7.
  • Such a slope grooming device is on its own generally known, so that this will not be discussed in more detail got to.
  • the rear implement carrier 4 and the slope grooming device 5 are made by two hydraulic actuating cylinders 8 and 9 in their position with regard to height and inclination changed.
  • a lower hydraulic actuating cylinder 9 engages on the rear implement carrier 4 on.
  • the upper actuating cylinder 8 engages on a connection extension for the piste grooming device 5.
  • Both actuating cylinders 8, 9 are on Vehicle rear 2 articulated.
  • Both actuating cylinders 8, 9 are hydraulic Control means actuated, only in FIGS. 1 and 2 Hydraulic control means 11 shown for the upper actuating cylinder 8 is.
  • the hydraulic control means are controlled by a electronic control unit 10, which is provided with a memory in a map of different slope surface designs as well as assigned target settings for the height and / or inclination of the Snow groomer 5 are stored.
  • the electronic Control unit 10 an evaluation unit described in more detail below, which, depending on the result of a target / actual value comparison, actuation the hydraulic control means.
  • a path sensor 12 for indirect detection of the actual state of the slope surface P is integrated in the lower actuating cylinder 9.
  • the displacement sensor 12 is connected to the electronic control unit via a signal line S 1 .
  • the displacement sensor 12 transmits actual values of the relative displacement between the cylinder part which is articulated on the vehicle side and the piston part of the actuating cylinder 9 which is articulated on the rear implement carrier side.
  • Fig. 1 is a normal floating position in dashed lines of the slope grooming device 5 shown for processing a flat Slope is suitable.
  • the slope grooming device is in dash-dotted lines 5 shown for a tip processing. It is it is important that the smoothing device engages in the slope surface and forms a support point for the slope grooming device 5.
  • the evaluation unit of the control unit 10 issues a corresponding control command to the hydraulic control element 11 for the upper actuating cylinder 8 as a function of the corresponding target / actual value comparison, as a result of which the latter is extended or retracted in a suitable manner via the hydraulic control line H 1 in order to achieve the desired one To achieve the position and inclination of the slope grooming device 5.
  • a displacement sensor 13 is also integrated in the upper actuating cylinder 8 and is connected to the electronic control unit 10 by means of a further signal line S 2 .
  • this additional displacement sensor 13 also makes it possible, as an alternative, to use this displacement sensor 13 as a sensor for indirect detection of the actual values of the slope surface P to be processed.
