Definitions

  • the present invention relates to a method for operating a cover of a lifting roof, in particular a sliding / lifting roof, for closing a roof opening of a vehicle by means of a cover drive, the cover being arranged in a first relative position with respect to a roof skin surrounding the cover when the vehicle is stationary and the cover being moved from the first relative position into a second relative position when the vehicle is moving by a negative pressure force caused by a driving wind. Furthermore, the invention relates to a corresponding control device and a sunroof system of a motor vehicle.
  • a sliding sunroof of a motor vehicle is known in which a cover can be adjusted by means of an electric motor which can be reversed in its direction of rotation in order to realize an open or closed position of the cover with respect to a roof opening of the motor vehicle.
  • a known solution is to set the rest position of the cover in the Z direction of the vehicle to a correspondingly low position, the cover being displaced to a position in which the surface of the cover is essentially flush with the surrounding roof skin in the event of negative pressure forces which may occur due to driving.
  • this has the disadvantage that wetness accumulates undesirably on the outside of the cover when the vehicle is stationary.
  • An electrical positioning drive suitable for the operation of a lifting / sliding roof affected here is usually known from EP 0 692 400 Bl.
  • the drive has a switching wheel driven by a motor, on which permanent magnetic markings are applied.
  • Hall sensors are also provided, which are arranged such that they generate signals in accordance with the permanent magnetic markings. By means of electronics, these signals are evaluated together with actuation signals entered by a user and converted into corresponding motor signals. The motor then turns the ratchet wheel on its positioning path.
  • the present invention has for its object to provide a method and a control device for operating a lifting roof mentioned above, which avoid the aforementioned disadvantages of the prior art.
  • a lifting roof system is to be created which, even at high vehicle speeds, enables the sliding roof cover to be automatically adapted to the roof skin surrounding the cover.
  • the special feature of the method proposed according to the invention is that a physical quantity correlating with the vacuum force is determined and the position of the cover by means of the cover drive, depending on the detected size, corresponding to the direction of the vacuum force from the second relative position to a third relative position to change.
  • This makes it possible for the cover to be in its closed position, regardless of the respective driving mode, always in the same position relative to the roof skin surrounding it. With the appropriate adjustment, this single zero position enables a visually positive overall impression of the outer surface in the transition area between the cover and the adjacent roof skin. Because a possible loss of coverage between the sunroof cover and the surrounding roof skin is compensated for by actively moving the cover back to its original position, so to speak, and thus restoring the original covering. This also allows an automatic compensation of the mechanical play of the sunroof system and the inadequate rigidity of the sunroof.
  • the proposed method can be implemented and implemented simply and inexpensively without the need to make any changes to the lifting roof mechanism or drive mechanism and to the control electronics.
  • the third relative position preferably substantially coincides with the first relative position.
  • the position of the cover is only changed when a first threshold value of the size is exceeded. This enables a particularly simple and low-cost implementation of the method, since it is the same Another switching point in the sunroof drive is to be provided. It can also advantageously be provided that the cover drive has an additional switch-off position which is approached when the upper threshold value of the large value is exceeded and from which the large value is retracted when the lower threshold value is undershot.
  • the physical size is recorded continuously and the position of the cover is continuously changed accordingly.
  • the continuous operation only takes place from the first threshold value, the threshold value being able to be selected such that no measurable displacements of the cover occur below the threshold value.
  • the control device also proposed according to the invention for the operation of such a sunroof cover provides in particular sensor means for detecting the physical quantities or physical quantities as well as control means for generating a control signal for the cover drive which correlates with the respectively detected quantity. On the basis of the control signal, the cover is opened by means of the cover drive. From the second relative position m, a third relative position is moved in order to restore the cover of the cover to the cover skin as far as possible.
  • first sensor means for detecting an instantaneous speed of the vehicle and / or second sensor means for detecting a change in the position of the cover that occurs in the direction of the negative pressure force and / or third sensor means for detecting heat noise occurring on the cover as a result of the head wind can be provided his.
  • the sensor means mentioned can be used both alternatively and cumulatively.
  • corresponding first and / or second and / or third sensor means can be provided for the continuous detection of the large or large and control means for the continuous generation of a corresponding control signal for the cover drive.
  • the lifting roof system further proposed according to the invention provides in particular that a drive mechanism of the cover has an additional mechanical switching or locking point corresponding to the third relative position of the cover.
  • the invention can be implemented in a wide variety of ways, namely by reprogramming a control program (software) loaded into a control unit for the operation of the lifting roof, or alternatively by minor modifications to the mechanical or electrical part of the lifting roof drive.

  • a transition is made to a next waiting loop 12, in which a query is made as to whether the instantaneous speed v of the vehicle is greater than a presettable upper limit value GR , upper.
  • This limit value is chosen so that the negative pressure forces (so-called "wind load") that arise due to the vehicle speed only reach a range in which the cover begins to lift and is moved into a second relative position that deviates from the zero position.

Abstract

L'invention concerne un dispositif permettant de faire fonctionner le volet du toit ouvrant d'un véhicule. Quand le véhicule est à l'arrêt, le volet est dans une première position relative par rapport à la toiture qui l'entoure. Quand le véhicule se déplace, le volet passe, sous l'action d'une force de dépression due au vent relatif, de la première position relative à une deuxième position relative et ce, avec les étapes suivantes; a) détection (12, 14) d'une grandeur physique en corrélation avec la force de dépression; b) changement (13) de la position du volet à l'aide d'un mécanisme d'entraînement en fonction de la grandeur détectée à l'encontre du sens de la force de dépression de la deuxième position relative à une troisième position relative correspondant sensiblement à la première position relative. Ainsi, lorsque le volet est dans sa position fermée, il est toujours dans la même position relative par rapport à la toiture qui l'entoure et ce, quelle que soit la vitesse du véhicule.
