Description

  • The invention relates to a method for operating a flap device for a vehicle specified in the preamble of claim 1. Art. Furthermore, the invention relates to a flap device for a vehicle specified in the preamble of claim 8. Art Furthermore, the invention relates to a vehicle with a flap device.
  • Generally there is the problem with electrically operated flaps, for example in electrically operated tailgates for motor vehicles, which have a sensor device for relative position determination of the flap, that after disconnecting and re-applying the energy supply of the flap, a controller can no longer determine the absolute position which the flap is currently. This effect is exacerbated, for example, in a tailgate, as it can also be moved manually during a power interruption and thus can be in a different position after re-energizing the power supply than before disconnecting the power supply.
  • From the DE 10 2009 047 441 A1 is a method for operating an electrically operable flap of a flap device, in particular a tailgate of a motor vehicle, to take as known. The flap device disclosed therein comprises a sensor unit, by means of which a relative position determination of the flap is made possible, after reaching a predefined position of the flap, the current position indication of a current position of the flap is assigned, so that the movement of the flap in the direction of the open position to a predetermined maximum open position is limited. After applying a previously separate power supply to the flap device and before reaching the predefined position, the currently detected position indication is assigned to a provisional maximum open position, so that the movement of the flap in the direction of the open position is limited to the provisional maximum open position. In other words, after the power supply has been re-applied, the flap can only be electrically closed and not opened again, since the position actually taken after the power supply has been re-established is defined as a provisional maximum end position. This is intended to protect the flap against possible damage, since an absolute position determination after the immediate re-application of the power supply is not possible. This limitation of the electrical pivotability of the flap brings with it corresponding functionality losses, which an operator of the flap may find disturbing.
  • The DE 10 2006 039 257 A1 shows an adjusting device and a method for adjusting a movable body part of a motor vehicle. The body part is controllable by means of a control device, which changes from an operating state to a rest state when no adjustment of the body part takes place within a predetermined period of time. The position of the body part is detected and stored at the time when the control device has been set to the idle state. Once a manual adjustment of the body part takes place during the idle state, the control device is put back into the operating state, wherein the position of the body part is detected again and the previously stored when entering the idle state position is updated with this new position value.
  • It is an object of the present invention to provide a solution by means of which an improved operability of an electrically actuated flap is made possible, the flap itself and elements around the flap to be protected from damage.
  • This object is achieved by a method for operating a flap device for a vehicle and a flap device for a vehicle and a vehicle having the features of the independent patent claims. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the dependent claims.
  • An inventive method for operating a flap device for a vehicle with an electrically operable flap, in particular a tailgate, comprises the following steps:
    • - Moving the flap by means of a damper drive, which is controlled by a control device with a normal operating characteristic during a first state supplying the flap device with energy;
    • By means of the control device, detecting a re-application of a power supply to the flap device after a second state following the first state, in which the energy supply is separated from the flap device;
    • - detecting a requested movement of the flap by means of the control device; wherein the method according to the invention is characterized by the following steps:
    • By means of the control device, selecting a stored restart characteristic curve by means of which control parameters of the damper drive provided for moving the damper are determined, the restart characteristic differing from the normal operating characteristic in that the damper drive is at Using the restart characteristic without information about the absolute position of the flap is controllable; and
    • Moving the flap by means of the flap drive, which is controlled by the control device with the selected restart characteristic until the flap reaches a predetermined absolute position.
  • So while it is the subject of the DE 10 2009 047 441 A1 is provided to limit the electrical movement of the flap after re-applying a previously interrupted power supply to a closing movement, it is provided according to the invention that after re-applying a previously interrupted power supply to the flap device, the flap can be both opened and closed. The flap is thereby moved according to a specific restart characteristic curve, wherein the restart characteristic differs from the normal operating characteristic, with which the flap is moved, if an absolute position determination of the flap is possible. The restart characteristic can have such changed control parameters compared to the normal operating characteristic for controlling the damper drive and thus for moving the damper, that the damper can be moved more carefully after a restart of the damper device or a reapplication of the energy supply to the damper device. This makes it possible, the flap - despite a non-given absolute position determination of the flap - both further open as well as close. As a result, the functionality of the electrically operable flap is substantially fully given even after the power supply to the flap device has been interrupted.
  • Thus, an improved solution for operating a flap device after a re-application of a power supply is provided, by means of which an improved operability of the electrically operated flap is made possible, the flap itself and the adjoining elements are protected from damage. The flap can both be electrically closed after opening the power supply and can be opened further, on the other hand, the flap, its mechanics and surrounding elements are effectively protected by a method of the flap with a correspondingly provided restart characteristic from damage. Overall, this increases the ease of use for a user of the tailgate, as it can continue to electrically open and close the door after an interruption in the power supply of the flap device without having to intervene manually.
  • In an advantageous embodiment of the invention, in a control of the damper drive with the restart characteristic, the damper is moved at a lower speed than in a control of the damper drive with the normal operating characteristic. The slower movement of the flap after a re-application of the power supply is effectively protected against damage.
  • A further advantageous embodiment of the invention provides that the movement of the flap in the operation with the restart characteristic is stopped at a lower movement resistance presented to the flap than in the operation with the normal operating characteristic. For example, in the restart characteristic curve a correspondingly lower threshold value than in the normal operating characteristic curve can be predetermined, at which the movement of the flap is stopped. Since after reapplication of the power supply to the flap device - as already mentioned - no absolute position assignment of the flap is possible, the flap itself and its mechanics is effectively protected from damage by using more sensitive movement or anti-jam parameters, if the flap, for example, in a upper mechanical stop or even against an obstacle should drive.
  • In a further advantageous embodiment of the invention is selected by the control device after re-applying the power supply for an opening movement of the flap, a different restart characteristic than for a closing movement of the flap, wherein the restart characteristics differ such that the opening movement is slower than the closing movement and / or the opening movement of the flap is stopped at a lower resistance of the flap than during the closing movement. Usually, it is less critical if the flap is moved to a lower maximum end position, usually a corresponding lock, than if the flap were to travel in an upper mechanical end stop at too high a speed. By providing or selecting different restart characteristics for an opening or closing movement of the flap, this circumstance can be taken into account, so that after the restart, for example, a faster closing movement than an opening movement is made possible. Overall, this further allows an increase in the ease of use of the flap device.
  • A further advantageous embodiment of the invention provides that the control device again selects the normal operating characteristic as soon as the flap during operation of the Damper device with the restart characteristic has reached the absolute position. As a result, the flap is moved again as quickly as possible with the normal operating characteristic, whereby it can be moved again at the earliest possible time with a faster traversing or pivoting speed. If, prior to reaching the absolute position, a predetermined threshold value for a movement resistance to be provided for the flap should be exceeded, the movement of the flap is, of course, prematurely stopped in order to prevent it from being damaged.
  • Furthermore, it is provided according to a further advantageous embodiment of the invention that when moving the flap with the restart characteristic, a signal is output, by means of which it is indicated that the flap is moved in accordance with the restart characteristic. The signal may be, for example, a warning tone and / or, for example, a flashing signal, by means of which the user of the flap device is signaled in a simple manner that the flap is being moved in accordance with the restart characteristic curve. As a result, a user can see in a particularly simple manner that the flap has just been connected to a power supply again, and is therefore moved with changed movement parameters.
  • According to a preferred embodiment of the invention, it is provided that the flap is moved to a maximum open end position or a closed end position as the absolute position. The detection of the closed end position is particularly easy to detect because it can be detected, for example, by means of a suitable sensor device as soon as the flap has been moved into a lock. The maximum open end position can be detected, for example, that a designated limit switch is approached by the flap.
  • An inventive flap device for a vehicle comprises an electrically operable flap, in particular a tailgate, with a control device which is adapted to control a flap drive, by means of which the flap is movable, wherein
    • - The control device is adapted to control the damper drive with a normal operating characteristic in a valve device supplying the first state of energy;
    • - The control device is adapted to detect a reapplication of a power supply to the flap device after a second state following the first state, in which the power supply is disconnected;
    • - The control device is adapted to detect a requested movement of the flap; wherein the flap device according to the invention is characterized in that
    • - The control means is adapted to select a stored restart characteristic by which control parameters are set for controlling the damper drive, wherein the restart characteristic of the normal operating characteristic differs in that the damper drive is controlled using the restart characteristic without information about the absolute position of the flap; and
    • - The control device is adapted to control the damper drive according to the restart characteristic until the flap is in a predetermined absolute position.
  • Advantageous embodiments of the method according to the invention are to be regarded as advantageous embodiments of the flap device, in which case in particular the flap device comprises means with which the method steps can be carried out.
  • Furthermore, it is provided in an advantageous embodiment of the invention that the flap device comprises a position detector which is adapted to detect a relative position of the flap, wherein after reaching the predetermined position of the flap, the position detector can be calibrated to a value assigned to the predetermined position of the flap is. In other words, when the predefined position is reached, an absolute position specification with respect to the flap becomes possible again, since the flap is recalibrated again in this position. Accordingly, for a method of the flap after the calibration, the normal operating characteristic for moving the flap can be selected so that it can now be moved faster again and possibly also with modified anti-jamming parameters. In the case of the predefined position of the flap, it may be the already explained absolute position of the flap, for example the maximum open end position or the closed end position of the flap.
  • A vehicle according to the invention comprises a flap device according to the invention or an advantageous embodiment of the flap device according to the invention.
  • Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figures are not only in the respectively indicated combination, but also in others Combinations or alone, without departing from the scope of the invention.
  • Exemplary embodiments of the invention are explained in more detail below with reference to schematic drawings, in which:
  • 1 a schematic representation of a vehicle with a flap device, which comprises a control device, a damper drive and an electrically operable flap in the form of a tailgate; and
  • 2 a schematic side view of the in 1 shown vehicle, wherein the electrically operable tailgate is shown pivoted in three different positions.
  • In the figures, identical or functionally identical elements are provided with the same reference numerals.
  • In 1 is a vehicle 10 which is a flap device 12 with an electrically operated tailgate 14 trained flap includes, shown in a schematic view. The movement of the tailgate 14 is by means of a control device 16 controlled, which a flap drive 18 for moving the tailgate 14 according to one in the control device 16 stored characteristic. The flap device 12 further comprises a position detector, not shown here, which is adapted to a relative position of the tailgate 14 capture. This position detector detects during a movement of the tailgate 14 the change of the position of the tailgate 14 and transmits a corresponding information to the control device 16 , For cost reasons is usually in such flap devices 12 omitted a position detector for detecting the absolute position and instead only uses a position detector, the relative change in position of the tailgate 14 can be detected, for example in farm of a Hall sensor. The damper drive 18 can be formed for example as a translatory drive. Alternatively, the damper actuator 18 also be a rotary motor, which can cause a translational travel by means of a gearbox to the tailgate 14 to adjust.
  • For information regarding the absolute position of the tailgate 14 despite using a relative position detector, after reaching a predetermined position the tailgate 14 the position detector is usually calibrated to a predetermined value associated with the position of the flap. For example, a counter of the position detector can be set to zero when the tailgate 14 has reached a closed position. The closed position is particularly easy to recognize because, for example, a catching the tailgate 14 in a designated lock 20 particularly easy to detect. Alternatively or additionally, it is also possible that the position detector is then calibrated when the tailgate 14 has been moved, for example, in a maximum open upper end position, for example in a mechanical stop. However, as soon as the power supply from the damper device 12 is disconnected, the information goes on the absolute position of the tailgate 14 but lost again.
  • Based on 2 in which the vehicle 10 is shown in a schematic side view, a method is explained below, which after re-applying the power supply to the flap device 12 is carried out.
  • In the present case, the flap device 12 again with an energy supply of the vehicle 10 coupled after the flapper device 12 previously completely cut off from any energy supply. This is the tailgate 14 in the middle position, in which the tailgate 14 marked with a solid line. Immediately after re-applying the power supply to the valve device 12 is a user not shown here, for example via a remote control, a command, the tailgate 14 to pivot upwards. This requested movement of the tailgate 14 is by means of the control device 16 recognized. Subsequently, the controller selects 16 a restart characteristic by which control parameters for controlling the movement of the tailgate 14 provided damper drive 18 are fixed, wherein the restart characteristic differs from a normal operating characteristic. The normal operating characteristic is the characteristic that is generated by the control device 16 is used when the controller 16 an information regarding the absolute position of the tailgate 14 is present.
  • After selecting the restart characteristic, the tailgate becomes 14 then in the requested direction of movement, in this case upwards, by means of the damper drive 18 which moves from the control device 16 controlled according to the selected restart characteristic. The tailgate 14 is moved at a lower speed when moving in accordance with the restart characteristic than when operating according to the normal operation characteristic. Furthermore, the tailgate 14 when operating with the restart characteristic at a lower tailgate 14 opposing movement resistance than stopped in the operation with the normal operating characteristic. Due to the slower and more sensitive movement of the tailgate 14 after the restart or the re-application of the power supply, the tailgate 14 saved from possible damage. In the present case, in which the tailgate 14 first to be moved upward according to the user instructions, this can be moved so long, for example, according to the selected by the control device restart characteristic until the tailgate 14 in the upper end position, which is represented by the upper dashed line has been moved. Usually, the tailgate 14 in their upper end position on a corresponding mechanical stop.
  • In this maximum upper end position of the tailgate 14 As previously mentioned, the position detector is calibrated so that it is set to zero, for example, or assigned a different predetermined value, so that from now on an absolute position determination of the tailgate can be made 14 is possible. The control device 16 then selects the normal operating characteristic for further movement of the tailgate 14 as soon as it has been moved to the upper end position shown here, which corresponds to a predefined position.
  • Alternatively, it is of course also possible that the tailgate 14 is to be moved down from its middle position after re-energizing the power supply. The control device 16 selects after restarting the power supply also a corresponding restart characteristic, which differs in the requested closing movement of the restart characteristic, which is selected in the opening movement after re-energizing the power supply. This has the background that closing the tailgate 14 after a restart of the flap device 12 usually less critical than a further swinging the tailgate 14 because the tailgate 14 when further turning usually at some point in the direction of the castle 20 is moved, with the risk of damaging the tailgate 14 or the entire valve device 12 less than if the tailgate 14 should go too fast in the upper mechanical limit stop.
  • According to the selected restart characteristic for closing the tailgate 14 this will proceed until the tailgate 14 has been moved in its lower, also shown here by dashed lines position in its closed position, said closed position of the tailgate 14 Usually recognized by the fact that the tailgate 14 in the castle 20 snaps, wherein of the flap device 12 the operation of the lock 20 is recognized. After the tailgate 14 in its lower end position has been moved, in which the lock 20 has been pressed, the controller selects 16 also the normal operating characteristic, so that the tailgate 14 can be moved in a subsequent opening movement according to the selected normal operating characteristic.
  • To indicate to a user that the tailgate 14 is just moved with changed motion parameters, so with the selected restart characteristic, is indicated by means of a signal on a use of the restart characteristic. For example, a warning sound can be output or a corresponding optical signal can be output so that the user is in any case informed that the tailgate 14 is being moved with changed motion parameters.
  • This makes it easy for the user to understand that the tailgate 14 is not moved with their normal operating parameters, so a user will not be surprised if the tailgate 14 is moved at a reduced speed. As soon as the position detector has undergone a calibration by approaching a defined position, the warning signal extinguishes because the flap device 12 From this point on, it will be operated again with a normal operating characteristic curve.
