    -1- Description Title Method for recognizing a destination position of a display and/or control unit in a holding device and an associated display and/or control unit The invention relates to a method and a computer program for recognizing a destination position of a display and/or control unit in a holding device and an associated display and/or control unit.
    State of the art Both in the motor vehicle sector and in the case of two-wheelers, it is necessary to mount display and/or control units such as navigation equipment, speedometers or smartphones in the user's field of view.
    Some providers use a bayonet lock, where the display and/or control unit must first be inserted into a holder and then turned.
    After the display and/or control unit is locked in this way, the user can activate the function of this unit.
    It is an object of the present invention to provide a method and an apparatus that performs the method, wherein proper mounting and/or orientation of the display and/or control unit is provided for performing the further functions in the holding device.
    Revelation of the Invention
    The method of the invention or a computer program executing the method and an apparatus on which the method or computer program is executed are suitable for determining the destination
    9. position of a screen and/or control unit, for example a rest position, to be recognized in a holding device.
    The destination position can be determined such that the display and/or control unit assumes a predetermined orientation or arrangement with respect to the holding device in this destination position in which it is held or locked or fixed.
    It is also conceivable that the destination position is specified so as to allow an optimized data connection between the display and/or control unit and a transmitting and/or receiving module on or in the holding device.
    Of course, this optimized data connection can also be made possible with another or further transmitting and/or receiving module mounted or integrated in the vehicle on which the holding device is mounted.
    In order to recognize the destination position, the method or the computer program records a first measured value from a sensor of the display and/or control unit.
    In this case, essentially a sensor value must be recorded representing the position or orientation of the display and/or control unit, for example a mobile terminal.
    A transmission signal from a wireless signal transmission module, for example a Bluetooth module integrated in the container or on the vehicle on which the container is mounted, is also recorded as the second measurement value.
    The destination position is recognized or information is generated as a function of reaching the destination position by means of a comparison of the first measurement value with a first comparison value and a further comparison of the second measurement value with a second comparison value.
    For example, upon detecting insertion of the display and/or control unit into the holder with subsequent rotational movement in the bayonet lock with simultaneous increase in the received signal strength of the wireless signal transmission module's transmission signal, it is assumed that a latch whether fixing of the display and/or control unit has taken place in the holding device.
    With this knowledge, the
    3. control function can be activated automatically in the display and/or control unit without the user having to do it manually. In this way, the control function as well as the display function for transferred information is made available more quickly.
    A location value or orientation is registered with the first measured value of the sensor in the display and/or control unit. This can be, for example, an alignment of the display and/or control unit, but also a special location coordinate. It is also conceivable that several first measured values are also recorded, with which a movement of the display and/or control unit can be recognized. This first measurement value or the chronological order of several first measurement values is then compared with one (or more) comparison value(s) corresponding to a start position or a locking process. For example, it may be provided that the attachment of the display and/or control unit to a corresponding holder of the holding device is recognized via the first comparison value. Alternatively, it is also conceivable that the first comparison value represents a first predetermined orientation of the display and/or control unit with respect to the holder of the holding device, so that correct insertion into the holding device is recognized. In one embodiment of the invention, it can be provided that when several first measured values are acquired, a change in position of the display and/or control unit and in particular of a mobile terminal such as a smartphone is recorded. For example, the sensor values of an acceleration sensor or a rotation sensor are suitable for this. However, it is also possible to detect a movement, in particular an expected movement in the holding device, via the brightness differences via a light sensor. In this case, the first comparison value represents the movement of the display and/or control unit, which can be recognized by a comparison with the first measurement value.
    -4- Reaching the destination position is furthermore detected by detecting a transmission signal from a wireless signal transmission module, for example a Bluetooth module, which is attached to the holding device or to a vehicle to which the holding device is attached. The transmission signal can be detected by means of an associated receiver module in the display and/or control unit. By knowing both the location of the wireless signal transmission module and the transmission power of the wireless signal transmission module, a signal threshold value can be set as the second comparison value, whereby the correct mounting of the display and/or control unit in the holder according to the intended destination position is available. If the second measurement value now exceeds or reaches this signal threshold value, the method or system consisting of the method or computer program and the display and/or control unit can assume that the display and/or control unit is in the specified destination position. It can optionally be provided that a further condition must be met before the method detects the destination position. In this case, the holding device may have electrical contacts which only come into electrical contact with electrical contacts of the display and/or control unit in the destination position. This can be achieved, for example, by connecting elements of the mobile terminal in contact with corresponding connecting elements of the holding device. If a current, voltage or resistance measurement is performed at these electrical contacts by the display and/or control unit or the holding device, a contact and thus the destination position can be recognized.
    In a particular embodiment of the invention, it is provided that there is an existing wireless connection between the display and/or control unit and the holding device or wireless signal transmission module before being plugged into the holding device. In this case, the first and/or second comparison value can be sent over the wireless connection,
    with which to recognize the start and reaching the destination position. The advantage of such a transfer of the corresponding comparison values from the container or vehicle on which the container is attached to the display and/or control unit is that the comparison values transferred reflect the specific geometries and may contain conditions as they exist in the holding device. Thus, the second comparison value may contain a signal threshold that is matched to the required geometric distance between the destination position and the Bluetooth module.
    Optionally, it can be provided that the first and/or second comparison value has a range of values, for example 1%, 2%, 5% or 10% around an average value. In this way, manufacturing accuracy or varying mounting conditions of the retaining device on the vehicle can be compensated for. The present invention can be applied particularly advantageously to two-wheeled vehicles such as bicycles and electric bicycles. For example, a smartphone can be used as a speed indicator or as a control unit for the electric motor. However, this requires a corresponding secure holder in the associated holding device to prevent damage due to accidental falling out or inaccurate locking. In addition, especially with wireless data transmissions, for example via Bluetooth, a defined signal strength is required to ensure the control and also the feedback of the data from the two-wheeler. This requires a minimum strength of the signal reception, which is achieved by a specific setting of a minimum distance from the transmitter module in the holder to the receiver module of the smartphone. The same applies, of course, to the transmission of control signals from the smartphone to the receiver module of the Bluetooth module. Brief description of the drawings
    6. The block diagram in figure 1 schematically shows an evaluation unit according to the invention, such as can be arranged, for example, in a display and/or control unit. One possibility for designing the method according to the invention is shown in the flow chart in figure 2.
    Embodiments of the Invention Referring to the block diagram of Fig. 1, the principle of an apparatus executing the method according to the invention or the corresponding computer program will be described. In this case, a control unit 100 is provided which is suitable for evaluating the recorded measured values. This control unit 100 may be attached to a retaining device as an independent unit or may be part of a further device which is inserted into the retaining device and finally locked or fixed. In particular, it may be provided that the control unit 100 is part of a display unit, for instance a speedometer. In addition, the control unit 100 may also be part of a mobile terminal, such as a smartphone.
    The control unit 100 optionally has a memory 110 in which comparison values for carrying out the method or for recognizing the destination position can be stored. Further, the control unit 100 detects first measurement values from a sensor 120 present in the display and/or control unit 100 or in the mobile terminal. This can be an acceleration sensor, a rotational speed sensor, a position sensor, an inclination sensor, an angle detecting sensor, but also a GPS or other location identification module. The control unit 100 also detects second measurement values from a wireless signal transmission module 130, for example a Bluetooth module, which is provided on the holding device in which the display and/or control unit 100 is to be placed. Alternatively, the wireless signal transmission module can also be mounted separately from the retaining device to a vehicle to which the retaining device is mounted. Furthermore, it is optionally possible
    -7- that an electrical connection is detected via electrical contacts 140 on the display and/or control unit 100. Furthermore, a wireless connection can optionally be provided, with which the wireless signal transmission module 130 or a further transmission module 150 transmits corresponding first and/or second comparison values to the display and/or control unit. Thus, the comparison values transmitted and received and stored by the display and/or control unit 100 in this manner can be individually adapted to the intended dimensions, geometries and/or arrangements of the holding device and the arrangement of the wireless signal transmission module 130 on the vehicle.
    After recognizing that the display and/or control unit 100 has reached the destination position in the holding device, the evaluation unit in the display and/or control unit 100 can automatically perform a function of the display and/or control unit 100 or control a part 160 of the vehicle. Optionally or additionally, the user can also be informed visually or acoustically by means of an associated device 170 about the detection of reaching the destination position.
    The destination position can be defined as a locking position of the display and/or control unit 100 in the holding device in which the display and/or control unit 100 is locked or fixed. This prevents the display and/or control unit 100 from being removed from the user or falling out of the holding device without further action. Furthermore, the destination position can be defined as the preferred orientation of the display and/or control unit 100 in the holding device. For example, it can be ensured that, when using a smartphone, the screen in the holder device is fixed lengthwise in the holder device in order to enable the widest possible display. Such views are useful for navigation purposes, for example. Alternatively, it can be provided that the screen is aligned longitudinally to take up as little space as possible on the handlebars of a two-wheeler.
    -8- After the method or the computer program has been started, in a step 200 at least a first measured value of a sensor 120 in the display and/or control unit 100 is registered. This first measurement value can be, for example, a sensor value of an acceleration sensor, a rotational speed sensor, a brightness sensor, usually a position sensor or an inclination sensor. Of course, a combination of sensor values can also be detected to detect the orientation and/or positioning of the display and/or control unit 100 relative to the holding device. In a further step 210, a transmission signal from a Bluetooth module 130 is recorded. The two steps 200 and 210 can be acquired sequentially, in parallel or independently of the subsequent evaluation of the measured values from step 220. It is also conceivable that several measured values are recorded to detect a change in the measured values over time. In this way, a movement of the display and/or control unit 100 or a change in the signal strength of the wireless signal transmission module 130 can be recognized.
    In order to evaluate the recorded first and second measurement values, in step 220 the first measurement value is compared with a first comparison value. This makes it possible to determine whether the display and/or control unit 100 is inserted into the holding device. By further acquiring first measurement values from the same or another sensor, it can be recognized whether the movement of the display and/or control unit 100 is suitable to allow locking and/or fixation in the holding device. A rotation, which is typical for the use of a bayonet lock, can therefore be recognized by the sensor values. However, a sliding movement can also be detected by means of the sensor values, which is also used in some well-known holding concepts. If no typical movement for locking or fixing the display and/or control unit 100 in the holding device is detected by the comparison in step 220, the method can be run again with acquiring the first measurement values.
    -9. In a next step 230, the recorded second measurement value is compared with a second comparison value. The second comparison value represents a minimum signal strength that must be achieved to detect a secure locking of the display and/or control unit 100 in the holding device. At the same time, the minimum signal strength also ensures that the wireless transmission is sufficient for sending control signals and for receiving operating parameters. Step 230 can take place both before and after step 220 and also independently of this step. If it is acknowledged that the minimum signal strength is not reached, the acquisition of measurements can be restarted in step 200 or alternatively only new second measurements can be acquired in step 210.
    If it is recognized in step 220 that a move suitable for locking has been performed and the transmission strength of the received signal from the wireless signal transmission module is higher than a minimum signal strength, in the next step 240, a signal is generated that matches the signal. - rectifying the destination position represents the locking position or the desired orientation of the display and/or control unit 100 . This signal can be transmitted visually or acoustically to the user of the vehicle.
    In a further embodiment of the invention, the first and/or second comparison values may be specified as a magnitude interval. It is conceivable that the minimum signal strength, assuming an average value, is considered to be achieved if the deviation from the average value is 1%, 2%, 5% or 10%. Optionally, such an increase in the tolerance for recognizing the destination position can also be selected by the user. This case is conceivable, for example, if the holding device is mounted separately from the Bluetooth module on the vehicle, for example on the steering wheel, and the distance has to be increased because of the distance.
    -10 -
    Optionally, in a next step, 250 components of the two-wheeled vehicle to which the holding device is attached can be controlled based on the detection of reaching the destination position.
    For example, the motor of an electric bicycle can be automatically put on standby so that it is easy to go out.
    Alternatively or additionally, the initialization of the connection of a wireless connection to a Cloud server can also be started.
