Description

A method for determining a user authorization of a user of a motor vehicle

DESCRIPTION:

The invention relates to a method for determining a user authorization of a predestined user of a motor vehicle. The predestined user is an expected user of the motor vehicle, or, in other words, an anticipated or predetermined user of the motor vehicle.

Piloted motor vehicles can perform a longitudinal control and a lateral control of the motor vehicle fully autonomously, i. drive without driver intervention. Piloted motor vehicles can be used as taxis, for example. This creates the problem that recognition of the passenger by the motor vehicle is difficult to achieve. Even with teilautonom or manually controlled motor vehicle in which, for example, a taxi driver can sit, there is the problem that the driver usually does not know who to pick up. So the questions arise as to how the potential passenger recognizes the taxi, for example in a metropolis, where there are many taxis, and how the taxi recognizes the right person.

So far, recognizing a passenger has been accomplished by the passenger identifying with a gesture or voice. Nevertheless, it can happen that someone pretends to be the passenger and pushes forward.

From the prior art, the US 2015/0339928 A1, DE 10 2015 010 748 A1 and US 2015/0279131 A1 address this problem. US 2015/0279131 A1 describes the recognition of the desire of a user by a gesture recognition device of the motor vehicle. However, this does not solve the above-mentioned problems because even an unauthorized user can execute these gestures. US 2015/0339928 A1 describes a system for controlling a motor vehicle fleet. When the autonomous motor vehicle arrives at a pickup location at which the motor vehicle is to pick up a user, the motor vehicle can recognize a mobile terminal of the user.

DE 10 2015 010 748 A1 describes a method for switching a transport service, wherein an autonomous transport motor vehicle can receive position data of an interested transport service customer and then autonomously adapt its direction of travel accordingly.

US 2016/0301698 A1 describes a technology for authorizing a passenger of an autonomous vehicle to use the motor vehicle as a taxi.

The described picking up of an interested transport service customer does not solve the above-mentioned problems. The proposal to detect a user's mobile terminal is a consideration for solving the above-mentioned problems. This solution is sufficient in an area where there are few vehicles, for example, on land or in a village. However, in a large city, where there are a great many taxis, there is still the problem of allocating the passenger the correct motor vehicle - and the motor vehicle to the correct passenger.

An object of the invention is to improve an association of motor vehicle and user to each other.

The object is achieved by the method according to the invention and the devices according to the invention according to the independent patent claims. Further advantageous developments are given by the dependent claims.

The invention is based on the idea of using two different codes for such allocation and for determining a user's authorization to use. For this purpose, a recognition code is used, which is preferably easily recognizable by a person and can be, for example, a picture code, as well as an authentication code, with which the user can assist with the Motor vehicle can authenticate. Using the recognition code, the user can recognize the motor vehicle assigned to him.

The method according to the invention for determining a user authorization of a predestined user of a motor vehicle initially comprises steps carried out by an association device, which comprise providing a recognition code for identifying the motor vehicle and providing an authentication code for authenticating the user, as well as transmitting the recognition code and the Authentication codes to a mobile terminal of the user and to an authentication device of the motor vehicle. In the latter step, the recognition code and the authentication code are transmitted to the mobile terminal, and the recognition code and the authentication code are sent to the authentication device.

An associating device is understood to mean a device or a device component which is set up to generate a recognition code and an authentication code and may have, for example, a software and / or a control board. The authentication device of the motor vehicle is understood to mean a device component or a device which may comprise a software and / or a control board and is set up to communicate with other devices or device components to read a code. The identification code can preferably be a code from an easily recognizable combination of symbols and / or colors and / or numbers. The identification code is used to identify the motor vehicle, ie that the user can easily recognize the motor vehicle from the outside, which is the motor vehicle assigned to him. Authentication code may preferably be a code less easily recognizable by the user, for example a bar code, and may preferably be designed such that it can hardly be copied by another person. The authentication code is used to authenticate the user. The authentication device of the motor vehicle transmits the identification code to a display device of the motor vehicle for outputting the identification code to an external environment of the motor vehicle. For this purpose, the authentication device preferably generates an output signal that can describe the identification code and transmits the output signal to the display device. A display device is understood to be a device or a device component that is set up to display information and, for example, may have a screen. By the display device so the identification code can be displayed, for example, on a screen on a motor vehicle side.

By a sensor device of the motor vehicle is a detection of the authentication code from the mobile terminal. A sensor device is a device or a device component for detecting a property of the environment of the motor vehicle, in particular a device or a device component with a sensor for detecting the authentication code from the mobile terminal. For this purpose, the user can, for example, hold the mobile terminal to a sensor device of the motor vehicle, which, for example, has a scanner and can be arranged on a door latch of the motor vehicle.

The authentication device performs a comparison of the detected authentication code of the mobile terminal with the authentication code received from the allocation device, and depending on a result of the comparison, the determination of a user authorization of the user takes place. For example, the comparison may show that the authentication code transmitted by the assignment device to the mobile terminal matches the authentication code transmitted by the assignment device to the authentication device. The authentication device may then determine that the user of the mobile terminal is authorized to use the motor vehicle and thereby authenticate the user. When determining the authorization to use, unlocking of a motor vehicle door can preferably take place.

The inventive method brings advantages, especially in large cities. For example, a piloted taxi can be detected very easily and quickly using the recognition code. Likewise, the motor vehicle can recognize the user using the authentication code. The inventive method can be used both for piloted, as well as partially autonomous or manually operated taxis. In addition, the user does not have to disclose his name to use the motor vehicle, which is why his personal information is protected. By the method according to the invention, a hit rate in the correct ten assignment of a motor vehicle with a user achieved. Especially in unsafe areas, the inventive method and the devices according to the invention constitute an additional safety system that is also used in non-piloted motor vehicles.

The mapping device provides a geographical map with pickup coordinates, the pickup coordinates describing a geographical point at which the user is to be picked up. The geographical map, which is to be understood as a digital geographical map, is transmitted to the mobile terminal, for example via an Internet connection. There is likewise a generation of a navigation signal which can describe the pickup coordinates, and a transmission of the navigation signal to a navigation device of the motor vehicle. As a result, users and motor vehicles are guided to each other.

It is provided that when approaching the motor vehicle to the Abholkoordinaten the outputting of the identification code by the display device takes place. For this purpose, the navigation device, which can be understood as a device or device component for navigating a motor vehicle and may include, for example, a navigation device, compare a current geographical position of the motor vehicle with the Abholkoordinaten and upon entry of the motor vehicle in a predetermined area in which the Abholkoordinaten are located then transmit the recognition code and / or a control signal for outputting the recognition code to the display device. This results in advantageous that in the presence of many such vehicles only those indicate the respective identification code whose Abholkoordinaten are in the vicinity. The passenger has to look through so fewer recognition codes and can find his assigned motor vehicle faster.

The providing of the recognition code can be done by generating an image signal describing an image, wherein the image can form the recognition code. Such a recognition code is a very easily recognizable recognition code that can be designed individually for the user, for example. For the user, it is so easy to recognize the motor vehicle. In addition, for example, the recognition code may be designed to be easily recognizable from a distance, for example, as compared to a license plate of the motor vehicle. The providing of the recognition code may include personalization of the recognition code, whereby the recognition code is personalized in dependence on a predetermined property or preference of the user. For example, the allocator may retrieve a user profile of the user, or the user may specify a preference to the associator, for example by typing in a keyword or specifying an image, while personalizing may provide, for example, a recognition code with a cartoon character if the user for example, a child, or, for example, a recognition code with a photo of the user or a relative or friend.

In accordance with a further embodiment of the method according to the invention, the allocating device can be used to associate the motor vehicle with the mobile terminal as a function of a travel route signal received from the mobile terminal, wherein the travel route signal can describe a journey planned by the user with a starting point and a destination point. Through such an assignment, the predestination of the user as a user of the motor vehicle can take place. This makes it possible to provide a platform for, for example, a taxi company, and in addition it is possible to logistically control which motor vehicle is assigned to which user.

As already described above, the method according to the invention can also comprise the output of the recognition code by the display device.

The object set out above is likewise achieved by an authentication device, which may preferably have a microcontroller and / or a microprocessor, wherein the authentication device is set up to perform the deceleration processes of an embodiment relating to an authentication device as described above. It results in the above advantages. The above object is also achieved by a motor vehicle, which may be preferably designed as a motor vehicle, for example as a passenger car. The motor vehicle according to the invention has a display device for outputting the identification code to an external environment of the motor vehicle, a sensor device for detecting the sensor. identification codes, and an embodiment of an authentication device according to the invention. The motor vehicle is characterized by an allocation device which is set up to carry out the method steps relating to an allocation device of a method step of a method of one of the embodiments described above. It results in the above advantages.

According to a further embodiment of the motor vehicle according to the invention, a display surface of the display device can be arranged fixedly on a rim and / or an axis of the motor vehicle. As a result, the recognition code can be better visible because it is not located on a body of the motor vehicle due to the positions of the display surface and thus is not displayed in a position where other motor vehicles often wear painted advertising or pictures.

Alternatively, the display surface may be rotatably mounted on a rim and / or a wheel of the motor vehicle, and the rim and / or the wheel may comprise a sensor device for detecting a rotation and / or a rotational speed of the rim and / or the wheel. The pointing device is set up to control a set of luminous elements of the display surface as a function of the detected rotation and / or the detected rotational speed. A luminous element is a component of the display surface which emits light and the totality of the luminous elements can thus output a display content. Such a designed motor vehicle can compensate for the display of the recognition code rotation of the display surface during operation of the motor vehicle, so that the recognition code for a viewer appears to be fixed. The object set out above is likewise achieved by an authentication device, which can have a processor device which can be set up to execute the method steps relating to an authentication device, an embodiment of the method according to the invention. For this purpose, the processor device can have at least one microprocessor and / or one microcontroller. Furthermore, the processor device may have a program code which is set up to execute the method steps relating to an authentication device of an embodiment of the method according to the invention when executed by the processor device. The Pro program code can be stored in a data memory of the processor device.

The invention will be explained in more detail by means of concrete embodiments with reference to the accompanying drawings. The exemplary embodiments explained below are preferred embodiments of the invention. In the embodiments, however, the described components of the embodiments each represent individual, independently of each other to be considered features of the invention, which each further independently form the invention and thus individually or in any other than the combination shown are to be regarded as part of the invention. Furthermore, the described embodiments can also be supplemented by further features of the invention already described. Functionally identical elements have the same reference numerals in the figures. It shows:

Fig. 1 is a schematic sketch of an embodiment of the method according to the invention, Fig. 2 is a schematic sketch of a further embodiment of the method according to the invention, and

3 shows a schematic sketch of a further embodiment of the method according to the invention, an embodiment of a mobile terminal with an example of a recognition code under a

Authentication code.

Fig. 1 shows schematically the principle of the method according to the invention with reference to a first embodiment. For this purpose, FIG. 1 shows a motor vehicle 10, which can preferably be designed as a motor vehicle, for example as a piloted passenger car. The motor vehicle 10 has an authentication device 12, which may be configured, for example, as a control board with a processor device 17. The processor device 17 may be, for example, a corresponding circuit of the authentication device 12.

The motor vehicle 10 also has a display device 14, which may have one or more display surfaces 16. The display device 14 can be designed, for example, as a display device that has a data th communication line (shown in FIG. 1 as a connecting line) may be connected to the authentication device 12. The display device 14 may have, for example, one or more display surfaces on or in a windshield 20, on a motor vehicle front side, for example in the region of a radiator grille, on a motor vehicle side, for example in the vicinity of a door latch of the motor vehicle 10, and / or on a wheel 18.

The display surface 16 may comprise, for example, light-emitting diodes (LEDs) as light elements. Suitable alternatives to this are known to the person skilled in the art.

The display surface 16 may, for example, be arranged fixedly on a rim 19 of the motor vehicle 10, and / or on an axle of the motor vehicle 10. Here, a fixed arrangement is understood to mean that the display surface 16 during operation of the motor vehicle 10 and a Turning the wheels 18 does not rotate. The display surface 16 may be configured, for example, as a screen, which may be attached to an end point of an axle. If the display surface 16, for example, arranged on a rim 19, an axis of the motor vehicle 10 or a wheel 18 motor vehicle that it can rotate with, it may, for example, on the axle and / or the wheel 18 and / or the rim 19th a sensor device 21 are located, which can detect, for example, a rotational angle and / or rotational movement of the wheel 18 and thus the display surface 16. A suitable sensor device 21 for detecting the angle of rotation and / or the rotation may comprise, for example, a rotary encoder or a gyrometer a tachometer.

A sensor signal describing this rotation or rotational movement can be evaluated by the display device 14, for example, and depending on a result of the evaluation, the display device 14 can generate, for example, a control signal that individual lighting elements (not shown in FIG. 1) of the display surface 16, preferably a totality of the lighting elements or a subset of the lighting elements, control, so that the rotational movement can be compensated. For a user looking at the display surface 16 from the outside, the image displayed by the display device 14 appears as a fixed image even though the display surface 16 rotates. The display surface 16, which may be arranged in FIG. 1 by way of example on a radiator grille of the motor vehicle 10, may be designed, for example, as a display (ie as a screen) or the identification code 27 can be arranged, for example, via a rear projection by means of a vehicle 10 arranged in the motor vehicle Projector can be projected onto a screen of the display surface 16.

In FIG. 1, the exemplary display surfaces 16 are shown as being disposed on an outer side of the motor vehicle 10, but alternatively, the display surface 16 may be disposed in an interior of the motor vehicle 10 such that the display surface 16 is externally, i. from outside the motor vehicle 10, is visible. Alternatively, the display surface 16 may be configured, for example, as a transparent screen on a pane of the motor vehicle 10.

The exemplary motor vehicle 10 of FIG. 1 also has a sensor device 13 for detecting the authentication code 25. This sensor device 13 may include, for example, a bar code scanner. In other words, the sensor device 13 can be designed as a reading device for a corresponding authentication code.

FIG. 1 likewise shows an allocation device 22, which can be configured, for example, as a control circuit board of a data server 23 remote from the motor vehicle. Alternatively or additionally, the allocation device 22 may comprise, for example, a computer program or a program code which may be stored in a data memory of the data server 23. The allocation device 22 can establish a data communication connection 28 with the authentication device 12 as well as with the mobile terminal 24, for example a wireless Internet connection or a WLAN connection. According to a further embodiment it can be provided that the allocation device 22 can be stored as program code on the mobile terminal 24 or in the authentication device 12 of the motor vehicle 10. In such a case, the data communication link 28 to the motor vehicle 10 or to the mobile terminal 24 may also be a wired data communication link 28, for example a data bus link.

The exemplary mobile terminal 24 shown in FIG. 1 may be, for example, a smartphone or a telephone or a tablet PC. The mobile Terminal 24 has a screen 26 that can display, by way of example, identification code 27, authentication code 25 and, for example, an image of a geographic map 30. The map 30 can show, for example, a current location 32 of the user and a current location 34 of the motor vehicle 10. Alternatively or additionally, the location 34 may also be a marked position, which may be marked as a pick-up location, ie as a location where the motor vehicle 10 picks up the user. The example mobile terminal 24 of FIG. 1 also displays a time indication 36 ("60 SEC"), which may indicate, for example, a pickup time or a remaining time until the arrival of the motor vehicle 10.

In the embodiment of FIG. 1, for example, the user can stand at Munich Central Station and need a taxi to Ingolstadt. With the aid of the mobile terminal 24, he can call, for example, at a taxi center to which, for example, the motor vehicle external data server 23 shown in FIG. 1 may belong. With the aid of, for example, an application program ("app"), the user can specify the city of Ingolstadt as the destination and the mobile terminal 24 can, for example, generate a travel route signal, and transmit this information by a travel route signal to the allocator 22 (S1).

The allocation device 22 can determine, for example via suitable logistics software, that a motor vehicle 10 is currently in the vicinity of the location 32 of the user and can be available. The determined motor vehicle 10 can then be assigned to the mobile terminal 24 (S2).

The allocation device can provide the identification code 27 (S3), that is to say generate it, for example, and also the authentication codes 25 (S4). It can be provided, for example, that the recognition code 27 can be a personalized recognition code 27. For personalizing the recognition code 27 (S5), the allocator 22 may, for example, retrieve a user profile of the user and capture a user-specific property of the user. If the user is a child, for example, an image of a comic character can be provided as identification code 27 (S3). An example of this is shown in FIG. 3. Alternatively, the recognition code 27 may be, for example, a photograph that the user of the mobile terminal 24 for example from a memory of the mobile terminal 24 and can transmit together with the travel route signal to the allocation device 22 (S1).

The recognition code 27 can preferably consist of a simple letter sequence or number sequence or symbol sequence or a single image, so that the user can quickly recognize the motor vehicle 10 assigned to him. For example, the recognition code 27 may be the name of the user, or the license plate of the motor vehicle 10. The advantage here is that such a recognition code 27 is easy and classic to recognize, especially by the demarcated from a license plate display by the display surface 16. Ist the recognition code 27 is the name of the user, the recognition code 27 is particularly simple and classically recognizable. In addition, the recognition code 27 is easy to remember. However, if a user's privacy is to be respected, or if it is intended to prevent confusion with other persons in the environment who may have the same name, then a recognition code 27, consisting for example of the license plate of the motor vehicle, is more advantageous Combination of symbols. The provision of the recognition code 27 (S3) can therefore be done, for example, by generating an image signal that can describe the corresponding image.

In method step S6, the assignment device 22 transmits on the one hand the recognition code 27 as well as the authentication code 25 to the mobile terminal 24 which can output the recognition code 27 and the authentication code 25. The authentication code 25 can be, for example, a barcode or a sequence of tones, wherein the exemplary sequence of tones can be output, for example, by a loudspeaker of the mobile terminal 24. Alternatively, the authentication code 25 may also be, for example, a pixel code as used in the prior art for, for example, airline tickets or train tickets. The authentication code 25 may alternatively be transmitted, for example, as a radio signal or via a wireless WLAN connection (S6).

On the other hand, the association device 22 transmits both the recognition code 27 and the authentication code 25 to the authentication device 12 of the motor vehicle 10 (S6). The authentication device 12 may, for example, an image signal containing the recognition code 27 to the display device 14, which then displays the recognition code 27 via the display surface 16 (S7).

In the example of FIG. 1, the recognition code 27 can be, for example, a succession of playing card symbols. By the individual identification code 27, the user can recognize exactly which motor vehicle 10 has been assigned. In contrast to using the name of the user as the recognition code 27, the privacy of the user is preserved, and a hit ratio of the correct assignment of the user and the motor vehicle 10 is increased if, for example, several people with the same name could be at the pick-up location 34.

Optionally, it can be provided that the allocation device 22 can determine a pickup location 34, ie a location at which the motor vehicle 10 picks up the user. The coordinates for this can likewise be transmitted with the geographical map 30 to the mobile terminal 24 and to the motor vehicle 10, in particular to the authentication device 12 or to a navigation device of the motor vehicle 10 (S8). In addition, the association device 22 can generate a navigation signal (S9) that can be transmitted to the navigation device of the motor vehicle 10 (not shown in FIG. 1), for example a navigation device, and used by the latter to control the motor vehicle 10. By way of example, a position signal, for example a GPS signal, the navigation device (not shown in FIG. 1) of the motor vehicle 10 can determine, for example, whether the motor vehicle 10 is at a predetermined maximum distance to the pickup location 34, and a control signal for outputting the recognition code 27 (S7) may be generated when the motor vehicle 10 is, for example, 20 meters or less away from the pickup location 34.

FIG. 2 shows by way of example an embodiment of the mobile terminal 24 which can display the identification code 27, the authentication code 25, and the card 30. The mobile terminal 24 may, for example, have a navigation device 38, which can determine, for example via a position signal, a current location 32 of the user. This current location 32 may also be displayed on the map 30, for example. So the user can see where he has to go to get to the pickup location 34. In the example of FIG. 2, the screen 26 of the mobile terminal 24 can additionally display the time indication 36 which, for that the user can travel 60 seconds ("60 SEC") to pickup location 34 or be picked up in 60 seconds. For example, a time measuring device (not shown in FIG. 2) of the mobile terminal 24 may be provided for the time indication 36, which may, for example, measure a current time and compare it with the pickup time transmitted by the assignment device 22.

The sensor device 13 shown in FIG. 1, when the user has arrived at the motor vehicle 10, the authentication code 25 detect (S10). For this purpose, the user can, for example, hold the mobile terminal 24 to the sensor device 13, so that the exemplary barcode can be scanned or read. In addition, it can be provided as an additional security measure that the identification code 27 can also be read. The sensor device 13 can then generate a sensor signal which can describe the detected authentication codes 25 and optionally the identification code 27. This sensor signal can be transmitted to the authentication device 12, which compares the detected authentication code 25 from the sensor device 13 by, for example, a suitable algorithm with the authentication code 25 received from the assignment device 22 (S1 1). If the two authentication codes 25 match, the user's authorization to use can be determined (S12). For example, a door of the motor vehicle 10 can be unlocked as a result of the determination of the use permission (S12).

Alternatively, the sensor device 13 may comprise, for example, a camera with, for example, an optical image recognition software. The sensor device 13 may, for example, be embedded in or secured to an outer skin of the motor vehicle 10. Alternatively, the sensor device 13 may, for example, be arranged behind a window of the motor vehicle 10, this alternative allowing simple retrofitting of the motor vehicle 10 with a sensor device 13.

The above-mentioned embodiments illustrate the principle of the invention to provide a system for recognizing, for example, ordered piloted taxis.

According to a further exemplary embodiment, for example, a taxi can be ordered via, for example, an app or a classic telephone. Preferably, by means of the mobile terminal 24. The association means 22, for example a system, may transmit a recognition code 27 to the mobile terminal 24 (S6), wherein the recognition code 27 may preferably consist of an easily recognizable combination of symbols, colors or numbers, and the allocation means 22 transmits an authentication code 25, which is preferably a less easily recognizable code, such as a bar code, so that the authentication code 25 can not be mimicked by another person in a hurry. The example easily recognizable code, the recognition code 27, may, for example, indicate to the user who ordered the taxi, for example, an automobile outside (S7), as the exemplary piloted taxi approaches. So the user can recognize the right taxi. The motor vehicle 10 can be opened, for example, only after the user has held his mobile terminal 24, for example a smartphone, on the sensor device 13-for example a reader or a reader on the outside of the motor vehicle 10. For example, all codes can be scanned there. If they match, the motor vehicle 10 can be opened.

In addition, the taxi or the sensor device 13 can be provided, for example, with a camera or cameras which, for example, can recognize a user's facial recognition from a distance and can drive to the user depending on the facial recognition. Alternatively, this can be done via an exchange of location data via the mobile terminal 24. The identification code 27 can also be generated or displayed abstractly (S6), for example using a matrix of luminaires on the exterior of the motor vehicle 10. By way of example, certain LEDs can light up, others can not and thus the identification code 27 can arise.

Advantageously, it follows that, for example, in a metropolis, a taxi can be easily recognized by the easily recognizable recognition code 27. The taxi can recognize or authenticate the user by means of the heavy code, ie by means of the authentication code 25. The exemplary symbols of the recognition code 27 may be adapted, for example, for example, to an age and / or the interests of the user. For example, children may, for example, use a cartoon character as a recognition code 27 get. This system can also be applied to taxis driven by one person.

The technical implementation can be done, for example, with a reservation system via a telephone or an app. Also, for example, software may be used to generate the codes. A determination of the location of the taxi and the user, for example, via GPS and / or the mobile device 24, such as a cell phone, done. The person can be recognized, for example, via facial recognition and / or the location of his mobile terminal 24. The display surface 16 or display surfaces 16, for example displays, can be arranged, for example, on an outer side of the motor vehicle 10. The sensor device 13, for example a code reader, can be arranged, for example, on an outer side of the motor vehicle 10.

According to a further exemplary embodiment, which can likewise be explained with reference to FIG. 1, the sensor device 13 can have, for example, a camera scanner and / or a scanner and / or a camera. On the wheels 18, for example, a respective display surface 16 can be arranged, in which LED points can compensate for a rotation of the corresponding wheel 18. Thus, the display surfaces 16, such as displays, compensate for the rotation. Alternatively or additionally, one or more display surfaces 16 may be provided as a fixed display surface 16 on an axis of the motor vehicle 10.

According to a further embodiment, a booking of the motor vehicle 10 may initially take place, including entering a destination, a location and / or a time. The system, that is to say one embodiment of the allocation device 22, can search for a motor vehicle 10. If a motor vehicle 10 is found, the assignment device 22 can send a recognition code 27, for example a recognition symbol, to, for example, a mobile phone or iPad as a mobile terminal 24 (S6) and an authentication code 25 (S6), for example a barcode, and / or one Map 30 with, for example, a location 34 of the motor vehicle 10 and / or a user's own location 32, and optionally an indication of where the user must go in order to be picked up.

Shortly before the motor vehicle 10 arrives at the pickup location 34, the identification code 27, for example a pickup symbol, can appear, for example. For example, on a display on a front window of the motor vehicle 10, on a display of a windshield of the motor vehicle 10, and / or as a projection on a front side of the motor vehicle 10. So knows the user, for example in a city with many piloted motor vehicles 10 or private cars that can be used in between, for example, as taxis, which motor vehicle 10 is intended for him.

When the motor vehicle 10 stops, the user can hold the exemplary mobile phone with the symbol and the bar code to the sensor device 13, for example a scanner or a camera. If these are ok, i. For example, when the user's permission to use is detected (S12), a vehicle door may open and the user may get in. In a further embodiment, which can also be explained with reference to FIG. 2, an exemplary pick-up / recognition symbol can be used as the recognition code 27 depending on the profile or interests or age of the person to be picked up (S3, S5). For example, a photo of a grandma or a cartoon character can be provided to a child (S3).
