DETAILED DESCRIPTION
In the figures the same elements or elements having the same function are indicated by the same reference signs.
FIG. 1 shows a schematic flow diagram of an exemplary implementation of a method for displaying visual content 1 (see FIG. 2 to FIG. 4 and FIG. 7) and/or of a method for providing a motor vehicle 2 (see FIG. 2 and FIG. 3). FIG. 2 and FIG. 3 show a motor vehicle 2 and a user 6 with a mobile electronic device 3 as well as an exemplary embodiment of a system 8 for displaying visual content 1 on the motor vehicle 2.
In step S1 of the method, a user 6 may input a user input concerning the visual content 1 to a user interface (not shown in the figures) of the mobile electronic device 3. The user request may comprise a request of the motor vehicle 2, for example in the context of a rental or sharing service. The computing system 7 may determine visual content data representing the visual content 1 depending on the user request received from the mobile electronic device 3.
In an embodiment, the user request data comprises data concerning an intended use of the motor vehicle 2, such as an expected route or time of use of the motor vehicle 2. The mobile electronic device 3 may transmit the user request, for example in a wireless manner, to a computing system 7 of the system 8 and/or of the motor vehicle 2. In another embodiment, the computing system 7 or parts of the computing system 7 may be arranged externally to the motor vehicle 2, for example in a remote or server computer system.
The computing system 7 may comprise one or more individual computing units which may or may not be spatially distributed. In an embodiment, the computing system 7 comprises one or more computing units of the motor vehicle 2. In another embodiment, the computing system 7 comprises, in addition or alternatively, one or more remote or server computing units (not shown in the figures). The one or more remote or server computing units may communicate wirelessly with other computing units of the computing system 7, for example of the motor vehicle 2.
In step S2, the computing system 7 may determine whether the user 6 has provided a user input concerning the visual content 1, for example in order to customize the visual content 1, to the mobile electronic device 3 and the mobile electronic device 3 has generated the user request data depending on the user input.
In step S3, the computing system 7 may determine visual content data representing the visual content 1 depending on the user request. To this end, the computing system 7 may select an appropriate visual content 1 depending on the specific situation or depending on the user request data and, in particular, depending on the user input, if available. Several variants of the visual content 1 may, for example, be stored on a database (not shown) of the motor vehicle 2 or the computing system 7.
In step S4, the motor vehicle 2 may be controlled by an electronic vehicle guidance system (not shown in the figures) of the motor vehicle 2 to move automatically to a boarding position depending on a position signal or on a position of the mobile electronic device 3. To this end, the mobile electronic device 3 may generate the position signal representing the position of the mobile electronic device 3 and transmit it to the computing system 7. Alternatively, or additionally, the electronic vehicle guidance system may determine the boarding position depending on map data retrieved from a map database, for example of the computing system 7.
In some embodiments, the position signal may be transmitted by the mobile electronic device 3 via Bluetooth, infrared communication, Wi-Fi, or other suitable communication signals.
In step S5, the computing system 7 may check the position of the mobile electronic device 3 again and determine whether it has been changed, for example, while the motor vehicle 2 has been moving from a parking position to the boarding position.
In step S6, the computing system 7 may select one of at least two windows 4a, 4b, 4c, 4d of the motor vehicle 2, such that the selected window is most suitable for displaying the visual content 1 depending on the position of the user 6. For example, when the user 6 is standing on a left side of the motor vehicle 2, the computing system 7 may select a left side window 4a of the motor vehicle 2, as shown schematically in FIG. 2, or, if the user 6 is standing on a right side of the motor vehicle 2, the computing system 7 may select a right side window 4b of the motor vehicle 2, as shown schematically in FIG. 3.
In some embodiments, the computing system 7 may select the window according to or depending on the position signal or the updated position signal of the mobile electronic device 3. In some embodiments, the computing system 7 may send a request signal to the mobile electronic device 3 to trigger the mobile electronic device 3 to generate and transmit the position signal or the updated position signal. The position of the mobile electronic device 3 may be understood as a relative position with respect to the motor vehicle 2. In other words, the window may be selected by the computing system 7 in a way that the user 6 is provided with a free view to the respective selected window of the motor vehicle 2.
In some embodiments, the computing system 7 may retrieve map information from a map database, which is, for example, stored on a storage element of the computing system 7, and select the window depending on the map information. The computing system 7 may determine from the map information, which side or which window of the motor vehicle 2 may be most suitable for displaying the visual content. To this end, the computing system 7 may, for example, take into account a probable position and orientation of the motor vehicle 2 when located in the boarding position and the user 6.
Depending on the selected window, the computing system 7 may adjust a light emission direction of a projection arrangement 5 of the motor vehicle 2 in order to project the visual content 1 on the selected window. In several embodiments, the projection arrangement 5 may comprise one or more light emitting units. The projection arrangement 5 may also comprise a driver unit to generate driver signals for the light emitting units depending on control data, which is generated by the computing system 7 depending on the visual content data and the selected window. Finally, the projection arrangement 5 may also comprise controllable optics, such as mirrors and/or lenses, to deflect light emitted by the light emitting units, in order to generate the visual content 1 and project it on the selected window.
In some embodiments, for changing or adjusting the light emission direction of the projection arrangement 5, the orientation of the whole projection arrangement 5, in particular the whole device including the optics and the light emitting units, may be changed or rotated. To this end, a motor and a drive of the projection arrangement 5 may be used.
In other embodiments, the light emission direction of the projection arrangement 5 may be adjusted by changing an orientation of the optics of the projection arrangement 5 or by using different light emitting units.
By adjusting the light emission direction and/or the orientation of the projection arrangement 5 depending on the selected window, the projection arrangement 5 may be put into the right position to project the visual content 1 on the particular selected window. In step S8, the projection arrangement 5 may then be controlled depending on the control data by the computing system 7 to project the visual content on the selected window.
FIG. 4 shows several examples for the visual content 1 that may be displayed on the selected window.
In the upper and panel of FIG. 4, an open lock symbol 1a is shown as well as a text portion 1b. The middle panel of FIG. 4 shows a check symbol 1c and also a text portion 1d. The text portions 1b, 1d may for example comprise a salutation directed to the user 6. The lower panel of FIG. 4 shows a closed lock symbol 1e and a further text portion 1f. The text portion 1f may for example inform the user 6 that the motor vehicle 2 cannot be accessed yet and/or when access to the motor vehicle 2 will be granted.
FIG. 5 shows an exemplary user interface of the mobile electronic device 3 that can be used to customize the visual content 1. For example, the user 6 may select his or her initials 1′ or another symbol to be displayed. In some embodiments, the user 6 may select a shape of a contour for the initials 1′ or symbol, such as a circle or a polygon. In some embodiments, the user 6 may select a color of the contour and/or the initials 1′ or symbol.
FIG. 6 shows a further exemplary user interface of the mobile electronic device 3 that can be used to customize the visual content 1. For example, the user interface may display a representation of a pattern 1′′ to be displayed on the motor vehicle 2. Furthermore, an image 1′′′ of the motor vehicle 2 with the pattern 1′′ may be shown.
FIG. 7 shows a further example for the visual content 1, comprising an image 1g of the user 6 accompanied by a text portion 1h, which may, for example, comprise potential or planned route information and/or booking information.
As described, the various aspects of the invention allow the user 6 to easily identify a motor vehicle 2 amongst others. In some embodiments, control may be given to the user 6 to customize the visual content 1 and also may take into account the location of the user 6 to choose the ideal window to show the visual content 1. When the vehicle approaches the user 6, for example controlled automatically, the window may be automatically selected and the customized visual content may be displayed.
In some embodiments, for requesting the motor vehicle 2, the user 6 may open his mobile phone or another mobile electronic device 3, enter a destination and then is provided with a user interface allowing him to choose a customized visual content. The user 6 may for example select amongst different colors, shapes and/or symbols for the visual content 1. The user 6 may select his or her initials or name or choose a pattern from a set of predefined available options. The user 6 may also choose his or her favorite color for the initials or add another outer contour of the symbol or add another icon or the like. The mobile electronic device 3 then sends the user request to the computing system 7 as described. As shown in FIG. 6, the user interface may also show the vehicle 2 together with a further representation 1′′ of the selected visual content 1 in various alternative ways on a screen of the mobile electronic device 3. As the motor vehicle 2 approaches the user 6, it may send a signal to the mobile electronic device 3 and the mobile electronic device 3 may signal that the motor vehicle 2 has arrived to the user 6, for example, by generating a haptic or visual or acoustic signal. Depending on the position of the user 6, obtained via the position of the mobile electronic device 3 or the map information, the projection arrangement 5 may rotate to the optimal window and send the projections on the side of the window the user 6 would be to display the visual content 1. The user 6 can then look at the visual content 1, for example his or her initials and/or custom pattern, and access the motor vehicle 2. In this way, the motor vehicle 2 is also able to personally greet the user 6 and the user 6 can easily find the motor vehicle 2. The user 6 can easily distinguish the intended motor vehicle 2 from others. Since the user 6 has actually selected the visual content 1, the user 6 may easily remember and look out for the selected visual content 1 to save time and effort.
In some embodiments, the motor vehicle 2 is a fully automatically drivable vehicle, which may, upon the user request, be moved fully automatically from a parking position to a boarding position, where the user 6 may wait to enter the motor vehicle 2. Since no human driver may be involved, the user 6 may easily identify the motor vehicle 2 among other vehicles. Furthermore, for example by customizing the visual content 1, the user 6 may easily confirm that the respective motor vehicle 2 is actually the right vehicle, without needing support of another person.
In some embodiments, the mobile electronic device 3 may be designed as a handheld electronic device, a mobile phone, a smartphone, a handheld computer, a tablet computer, a laptop computer and so forth.
In an embodiment, the system 8 for displaying visual content comprises the mobile electronic device 3.
In an embodiment, the user request data comprises data concerning an intended use of the motor vehicle 2 and the visual content data is determined by the computing system 7 depending on the data concerning the intended use. The visual content data is determined by the computing system 7 depending on data concerning the identity of the user 6, which is comprised by the user request. The data concerning the intended use may for example comprise an intended route and/or an intended time of use
