Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The schematic diagram in FIG. 1 schematically shows an evaluation unit according to an example embodiment of the present invention as may be present for example in a display and/or control unit. An example embodiment of the method according to the present invention is shown in the flow diagram of FIG. 2.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

[0015] On the basis of the schematic diagram of FIG. 1, the design is now described of a device that carries out the method according to an example embodiment of the present invention, or the corresponding computer program. Here, a control unit 100 is provided that is suitable for evaluating the acquired measurement variables. This control unit 100 can be attached to a holding device as a self-contained unit, or can be part of a higher-order device that is attached in the holding device and is finally arrested or fixed there. In particular, it can be provided that control unit 100 is part of the display unit, for example of a speed indicator. In addition, control unit 100 can also be part of a mobile terminal device such as a smartphone.

[0016] Control unit 100 optionally has a memory 110 in which comparison variables can be stored for carrying out the method, or for recognizing the target position. In addition, control unit 100 acquires first measurement variables of a sensor 120 that is in display and/or control unit 100, or in the mobile terminal device. This can be an acceleration sensor, a rotational rate sensor, a position sensor, an inclination sensor, a sensor for acquiring an angle, or also a GPS or some other location identification module. In addition, control unit 100 acquires second measurement variables of a wireless signal transmission module 130, for example a Bluetooth module, that is provided on the holding device in which display and/or control unit 100 is to be placed. Alternatively, the wireless signal transmission module can also be attached, separately from the holding device, to a vehicle on which the holding device is fastened. In addition, it is optionally possible for an electrical connection to be acquired via electrical contacts 140 on display and/or control unit 100. In addition, a wireless connection can optionally be provided by which wireless signal transmission module 130, or another transmission module 150, transmits corresponding first and/or second comparison variables to the display and/or control unit. The comparison variables sent out in this way and received and stored by display and control unit 100 can thus be individually adapted to the provided dimensions, geometries, and/or situations of the holding device, and to the situation of wireless signal transmission module 130 on the vehicle.

[0017] After the recognition that display and/or control unit 100 has reached the target position in the holding device, the evaluation unit in display and/or control unit 100 can automatically control a function of display and/or control unit 100, or of a component 160 of the vehicle. Optionally or in addition, the user can also be informed about the recognition of the reaching of the target position optically or acoustically, by a corresponding device 170.

[0018] The target position can be defined as a locking position of display and/or control unit 100 in the holding device in which position display and/or control unit 100 is arrested or fixed. In this way, display and/or control unit 100 is prevented from being removed without further action by the user, or from falling out of the holding device. In addition, the target position can be defined as a preferred orientation of display and/or control unit 100 in the holding device. Thus, it can for example be provided that, given the use of a smartphone, the screen is deliberately attached in the holding device lengthwise in order to offer as wide a display as possible. Such displays are required for example for navigation purposes. Alternatively, it can be provided that the screen is to be oriented in the longitudinal direction in order to take up as little space as possible on the handlebar of a two-wheeled vehicle.

[0019] After the start of the method or of the computer program, in a step 200 at least one first measurement variable of a sensor 120 in display and/or control unit 100 is acquired. This first measurement variable can be for example a sensor variable of an acceleration sensor, of a rotational rate sensor, of a brightness sensor, in general of a position sensor, or of an inclination sensor. Of course, a combination of sensor variables can also be acquired in order to detect the orientation and/or positioning of display and/or control unit 100 in relation to the holding device. In a further step 210, a transmit signal of a Bluetooth module 130 is acquired. Here, the two steps 200 and 210 can be acquired one after the other, in parallel, or independently of the following evaluation of the measurement variables starting from step 220. In addition, it is possible that a plurality of measurement variables are acquired in order to acquire a temporal change in the measurement variables. In this way, a movement of display and/or control unit 100, or a change in the signal strength of wireless signal transmission module 130, can be recognized.

[0020] In order to evaluate the acquired first and second measurement variables, in step 220 the first measurement variable is compared to a first comparison variable. In this way, it can be determined whether display and/or control unit 100 has been placed in the holding device. Through the further acquisition of first measurement variables of the same or of another sensor, it can be recognized whether the movement of display and/or control unit 100 is suitable to enable the arresting and/or fixing in the holding device. Thus, through the sensor variables a rotation can be recognized that is typical for the use of a bayonet coupling. However, the sensors can also recognize a sliding movement that is also used in some conventional holding designs. If no typical movement is recognized for the arresting or fixing of display and/or control unit 100 in the holding device through the comparison in step 220, then the method can be run through again with the acquisition of the first measurement variables.

[0021] In a further step 230, the acquired second measurement variable is compared with a second comparison variable. Here, the second comparison variable is a minimum signal strength that has to be reached in order to recognize a secure arresting of 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 adequate for the transmission of control signals and for the reception of operating parameters. Step 230 can take place both before or after step 220, or also independent of this step. If it is recognized that the minimum signal strength has not been reached, then the acquisition of measurement variables can be begun again in step 200, or alternatively only new second measurement variables can be acquired in step 210.

[0022] If in step 220 it is recognized that a movement suitable for arresting has been carried out, and if the transmit strength of the received signal of the wireless signal transmission module is above a minimum signal strength, then in the following step 240 a signal is produced that represents the correct reaching of the target position, the locking position, or the desired orientation of display and/or control unit 100. This signal can be communicated to the user of the vehicle optically or acoustically.

[0023] In a further specific embodiment of the present invention, the first and/or second comparison variable can be indicated as a size interval. Thus, it is possible for the minimum signal strength to be regarded as reached, starting from a mean value, if the deviation from the mean value is 1%, 2%, 5%, or 10%. Optionally, such an increase in the tolerance for the recognition of the target position can also be selected by the user. This case is possible for example if the holding device is attached to the vehicle separately from the Bluetooth module, for example on the handlebar, and the distance has to be made larger for reasons of space.

[0024] Optionally, in a further step 250, starting from the recognition of the reaching of the target position a controlling of components of the two-wheeled vehicle to which the holding device is attached can take place. Thus, for example the motor of an electric vehicle can automatically be put into operational readiness in order to permit uncomplicated starting. Alternatively or in addition, the initialization of the connection of a wireless connection to a cloud server can also be initiated.
