Definitions
- the invention relates to a method for controlling a motor vehicle door or motor vehicle flap, with a drive for a wing of the motor vehicle door or motor vehicle flap that is movable relative to a motor vehicle body, and also with at least one sensor for detecting individual or multiple static and/or or dynamic parameter of the wing, and with a self-learning control unit that evaluates the sensor values.
- motor vehicle doors or motor vehicle flaps for example motor vehicle side doors, motor vehicle tailgates or motor vehicle front hoods
- the drive for the associated wing which is movable relative to the motor vehicle body, is provided as the dominant component of the motor vehicle door or motor vehicle flap.
- the wing can be a side door wing, a tailgate wing or a front flap.
- other flaps or wings are also conceivable, such as loading flaps, sliding doors, etc.
- the drive of the movable wing in question can be used both in connection with an associated opening movement of the wing as well as in connection with a closing movement or both.
- vehicle users are used to supporting or at least initiating the movement of the sash in question.
- all the energy required by the drive for the wing of the drive is not required, but only partially. This ultimately depends on how the individual vehicle user applies the wing.
- the generic prior art according to DE 10 2006 057 679 B4 is about a device for closing a driven movable component and in particular a tailgate or door on a motor vehicle.
- a first detector device is designed to signal a closed state of the component.
- a second detector device With the help of a second detector device, a distance measurement is carried out as part of a switch-off device.
- a self-learning control system is implemented. In fact, several closing processes can be examined in such a way that an average value for a delay time during the closing process can be derived. As a result, the delay time can be changed dynamically, for example depending on the seasonal ambient temperature. Any adaptation to the user is once again not reflected.
- the invention is based on the technical problem of further developing such a method in such a way that conclusions about the user and his impact on the leaf of the motor vehicle door or motor vehicle flap can be derived and implemented.
- a generic method for controlling a motor vehicle door or motor vehicle flap is characterized in the context of the invention in that the control unit evaluates the parameters of the wing for user recognition.
- the control unit usually proceeds in such a way that the dynamic parameters of the wing are evaluated for user recognition.
- These dynamic parameters of the wing are, for example, temporal progressions of the wing movement. This can be a distance-time history, a speed-time history, an acceleration-time history, etc. individually or together.
- These dynamic parameters of the wing are now evaluated according to the invention for user recognition.
- a specific and characteristic path-time curve and consequently also a speed-time curve and acceleration-time curve of the sash can be determined for the user Closing and opening movements are derived and derived.
- This specific time course of the user is now evaluated for user recognition and taken into account by the control unit.
- the control unit can not only carry out a specific user identification based on the relevant time history, but can also fundamentally distinguish between different users based on the time history. Of course, averaging can be carried out to improve accuracy and better differentiation.
- control unit can carry out the user recognition implemented according to the invention based on the dynamic parameters of the wing and evaluate the questionable parameters of the wing for user recognition. As a result of this user recognition, the control unit can then recalibrate the drive for acting on the sash.
- a user applies a particularly “swinging” force to the sash in question during the opening and/or closing process
- this may be implemented and interpreted by the control unit in such a way that not only the user is recognized, but the drive undergoes the desired recalibration depending on his user identification .
- this means that the drive for the wing is reduced in terms of the power exerted on the wing.
- the drive will be adjusted and, if necessary, recalibrated depending on the user recognition carried out, so that it almost exclusively ensures the movement of the sash.
- control unit takes into account static parameters of the wing in the form of, for example, its mass.
- static parameters can, for example, be stored in the control unit by the manufacturer.
- the wing or its movement sequence depends not only on the application by the user, the previously described mass of the wing, but also on the friction of the wing relative to a bearing on the motor vehicle body.
- the control unit can now choose between these distinguish between different influencing variables, i.e. between the user, the mass of the wing and finally its friction in the bearing or the several bearings. This distinction can be made based on the movement of the wing, whereby additional and known values for the mass of the wing are taken into account if necessary.
- the user recognition is usually carried out based on the temporal sequence of movements, for example the maximum achievable speed, the speed curve and the temporal drop in the speed of the wing as it was acted upon by the user.
- the friction between the wing and the motor vehicle body has a largely static influence on the movement sequence in question, thus leading to a more or less significant damping of its speed.
- a rotation angle sensor is primarily used to record the dynamic parameters of the wing, i.e. to be able to record and evaluate the movement profile described as an example in the form of a path-time profile. All of these values, ie the dynamic movement sequence of the wing as a result of the user recognition, any static parameters in the form of the mass of the wing and its friction in the bearing with the motor vehicle body, are now implemented overall by the control unit in such a way that the control unit controls the drive of the wing depending on the values of the sensor for loading the wing recalibrated. In fact, values from both the current sensor and the rotation angle sensor are generally used at this point.
- control unit usually specifies different operating states depending on the values of the sensor in question. This means that a distinction can be made, for example, between normal operation, load operation or even overload operation.
- Normal operation corresponds to the control unit acting on the drive to act on the wing in such a way that it takes into account the user recognition as well as the detected mass and the friction and the drive also has the drive power required for this.
- the control unit ensures, for example, an increase in the drive power for the drive, which, for example, takes or can take into account increased friction of the wing relative to the motor vehicle body.
- overload operation corresponds to the fact that the friction and/or mass of the wing has increased to such an extent that the nominal drive power of the drive is no longer sufficient to be able to move the wing at all.
- the drive is not activated by the control unit, but instead, for example, an error message is output or overload operation is displayed.
- the invention also relates to a device which is particularly suitable for carrying out the method.
- a method and a device are described, with the help of which user recognition in particular can be carried out.
- the control unit usually carries out the user recognition in question depending on time-dependent values of the sensor.
- the control unit usually also takes into account static parameters of the wing in the form of its mass or the friction in a bearing or several bearings with the motor vehicle body.
- the drive for acting on the wing can be recalibrated and ultimately the energy required for the drive adjust accordingly. All of this is achieved through a learning process of the control unit depending on the dynamic and static parameters of the wing.
- the corresponding recalibration can be carried out and implemented through routines using, for example, artificial intelligence.
- the calibration that takes place during operation in the example case takes into account any changes in the movement of the wing, among other things with regard to the observed friction conditions.
- This provides an overall high-quality tactile operation of the sash, which can be implemented with particularly little effort and ease. This is where the main advantages can be seen.
- Fig. 1 shows the device according to the invention for controlling a
- Fig. 2A shows a movement sequence in the form of a speed
- Fig. 2B shows the current drawn by the drive over time schematically.
- the figures show a device for controlling a motor vehicle door or motor vehicle flap.
- the device is one with the help of which a motor vehicle side door is controlled.
- the motor vehicle side door has a wing 2 that can be moved relative to a motor vehicle body 1.
- the wing 2 of the motor vehicle door or motor vehicle side door is equipped with a motor vehicle Lock 3 equipped, of which only schematically a locking mechanism 4, 5 consisting of a rotary latch 4 and a pawl 5 interacting with it are shown.
- the motor vehicle lock 3 or its locking mechanism 4, 5 interacts with a body-side lock holder or striker 6.
- the sensor 9, 10 or the two sensors 9, 10 serve to detect individual or several static and/or dynamic parameters of the wing 2.
- the control unit 8 now evaluates the values of the sensor 9, 10 or the rotation angle sensor 9 as well as the current sensor 10 out. According to the invention, the signals in question from the sensor 9, 10 and thus the parameters of the wing 2 are now evaluated by the control unit 8 for the purpose of user recognition.
- FIG. 2A shows the movement of the wing 2, specifically shows two different curves of the speed v of the wing 2 over time t. These two speed curves show a speed v of the wing 2 that starts from the origin 0 and increases differently over time t.
- the drive 11 for the wing 2 may provide support for the closing movement of the wing 2 shown at this point.
- wing 2 is in The example case shown in FIG. 2A is closed both manually and by a motor.
- the time t2 then corresponds to the closed state of the leaf 2, which is manifested based on the closed state of the associated motor vehicle lock 3. This closing state is reported to the control unit 8 using the sensor 7.
- a speed threshold v s is also shown in FIG. 2A.
- This speed threshold is not exceeded by a first user belonging to the lower (dash-dotted) curve, but is exceeded by the second user belonging to the upper (solid) curve.
- the drive 11 can provide support for the closing movement of the sash 2 for the first user with a speed curve below the threshold v s , whereas the closing movement of the sash 2 for the second user above the threshold v s is not additionally supported by a motor.
- the threshold v s can be specified by the control unit 8 in a variable and displaceable manner.
- the speed-time curve v(t) in FIG. 2A ultimately represents the signal of the rotation angle sensor 9
- the current curve over time l(t) in FIG. 2B ultimately presents the values of the current sensor 10.
- the time corresponds ti causes the current I drawn by the drive 11 to increase at this point, up to a maximum at time t2. i.e. in the case that the wing 2 has reached its closed state relative to the motor vehicle body 1. This closing state is detected again using the sensor 7 inside the motor vehicle lock 3 and reported to the control unit 8.
- the control unit 8 can now control the parameters of the wing 2, that is, both the dynamic parameters of the wing 2, i.e. its movement sequence according to FIG evaluate.
- the Control unit 8 selects the dynamic parameters of the wing 2, as can be seen from FIG. 2A.
- the respective user creates a movement profile that is characteristic of him or a characteristic movement sequence over time, which is shown and reproduced here using the speed-time curve v(t).
- the control unit 8 can distinguish between different users.
- control unit 8 “knows” that when the wing 2 is acted upon by the first user belonging to the lower (dash-dotted) speed profile, the drive 11 must intervene to provide support, and for the second user belonging to the upper (solid) speed profile, additional support is little or no is required.
- control unit 8 can take into account static parameters of the wing 2 in the form of its mass.
- the current sensor 10 can provide information about this, as can any friction in a bearing between the door leaf 2 and the motor vehicle body 1. In fact, the bearing is shown here as a schematic point at which the drive 11 for the wing 2 engages.
- any increasing mass of the wing 2 and/or its friction in the bearing in question relative to the motor vehicle body 1 leads to the current intensity I measured by the current sensor 10 and recorded by the drive 11 increasing, as shown schematically in FIG. 2B .
- the one operating state associated with the dashed curve of the current intensity I corresponds to normal operation, whereas the curve of the current intensity I shown in solid lines over time t corresponds to load operation.
- the drive 11 is subjected to the maximum possible current in the example case. If an even higher current intensity is required to act on the drive 11, for example as a result of increased friction, the so-called overload operation is observed, which occurs beyond a threshold for the current intensity l s in FIG. 2B.
- This overload operation corresponds to the control unit 8 not acting on the drive 11 for the wing 2.
- control unit 8 takes into account static parameters of the wing 2 in the form of its mass or the friction relative to the motor vehicle body 1.
- the corresponding values are recorded using the current sensor 10, which is provided on the drive 11 and for recording the static parameters of the wing 2 is provided.
- the control unit 8 ensures that the drive 11 is recalibrated depending on the values of the sensor 9, 10 for acting on the wing 2.
- control unit 8 allows a correspondingly increased current consumption of the drive 11 or ensures that the Drive 11 and its loading must be recalibrated accordingly.
- the control unit 8 can, depending on the values of the sensor 9, 10, specify the different operating states already described with reference to FIG. 2B, such as the dashed normal operation, the solid-line load operation and finally the overload operation beyond the threshold ls .
