Description

[0001] The invention relates to a method for displaying an identified vehicle in an environment. Furthermore, the invention relates to a mobile terminal for this purpose.

[0002] If a user selects a vehicle, for example, during a selection process when booking a vehicle, the user may need to be able to identify the selected vehicle from a large number of vehicles in the area. To support vehicle identification, relevant vehicle information can be displayed to the user on a user-specific mobile device.

[0003] DE 11 2016 005 347 T5 discloses a system for providing a vehicle rating for a vehicle capable of connecting, in particular wirelessly, to a transit hub, another vehicle, and a device. The device comprises a camera for capturing an image, a stored photo application (photo app) for optically recognizing the image, and a display for displaying a map, received vehicle information, and a position of the vehicle for identifying the vehicle.

[0004] A disadvantage of the system from the above-mentioned publication is that the surroundings of the vehicle are only displayed in a highly simplified bird's-eye view and it is necessary for a user to compare the received vehicle information with characteristics of all vehicles in the surrounding area in order to identify the vehicle.

[0005] DE 10 2015 005 696 A1 describes a method for operating a motor vehicle, wherein an environmental feature (object or event) is superimposed into the vehicle's surroundings to warn and / or inform a driver of a motor vehicle. A display device provides a representation of the vehicle's surroundings from a perspective of the motor vehicle using a camera and a screen of the motor vehicle or a portable terminal. Based on relative coordinates of the environmental feature, a position marker and / or a highlight of the environmental feature is superimposed into the representation of the vehicle's surroundings.

[0006] Furthermore, DE 10 2014 208 310 A1 describes a driver assistance system for a vehicle for displaying augmented reality. A receiving unit receives a first image signal, which is generated by a sensor of the vehicle, another vehicle, and / or a stationary infrastructure facility and contains an environmental area obscured by an environmental object. Using an additionally detected line of sight of a driver, the display is adapted to the driver's current perspective. The evaluation unit calculates a second image signal, which corresponds to a virtual view of the driver of the environmental area, and sends it to a display unit for partially transparently displaying the second image signal. The display unit is designed, for example, as a mobile user terminal comprising a camera and a screen.

[0007] To improve the display of the vehicle's surroundings, the last two publications mentioned above disclose a representation of the surroundings using augmented reality to display a hidden object or a hidden area of ​​the surroundings by overlaying it into the display of the surroundings. The disadvantage of this is that the surroundings are captured by a vehicle camera or a stationary camera. Thus, the surroundings are displayed to the driver of the vehicle for operation. However, the vehicle is not identified using the display of the surroundings.

[0008] US 2018 / 0 349 699 A1 discloses a method for identifying a vehicle. In an activated augmented reality mode, image data from a camera of a mobile device can be captured. If the vehicle is identified based on vehicle information stored in the mobile device, an augmented image display can be provided on a screen of the mobile device, which can include image data from a real-time recording and augmented data.

[0009] US 2018 / 0 075 287 A1 discloses a method for identifying a target vehicle, wherein a wireless signal transmitted by the target vehicle is received by an image detector of a mobile device. If the target vehicle is identified as a source of the radio signal, the identity of the target vehicle can be displayed to a user on a display of the mobile device.

[0010] Furthermore, US 2018 / 0 374 002 A1 describes a method for vehicle identification. To recognize a pre-booked autonomous vehicle, the vehicle can have a unique identification object (e.g., display panel, symbol) on an exterior of the vehicle.

[0011] The object of the present invention is to provide a method for displaying an identified vehicle in a particularly user-friendly manner.

[0012] This object is achieved by the subject matter of the independent patent claims. Advantageous embodiments with expedient and non-trivial refinements of the invention are specified in the dependent claims, the following description, and the figures.

[0013] The invention provides a method for displaying an identified vehicle in an environment by means of a mobile terminal, wherein in a representation of the environment at least one display symbol, for example a graphic element, of the identified vehicle is superimposed with at least one recognized object of the environment.

[0014] The method according to the invention comprises several steps that are carried out by devices on the mobile terminal and / or a server. The mobile terminal is, for example, a mobile phone or smartphone, a tablet, or a wearable computer, and the server is, for example, an external computing device of an external service provider, such as a passenger transport broker. The devices required to carry out the method include a transmitting and receiving device for transmitting and receiving data via an established communication connection, a detection device for detecting the surroundings, and an evaluation device for evaluating and generating data. The mobile terminal has a display device for displaying the identified vehicle in the surroundings.In this context, data refers to identification data of the vehicle, environmental data of the environment, and object data of at least one object.

[0015] To identify the vehicle, the identification data is received by the receiving device, with the identification data being received by the receiving device via the aforementioned communication connection. For this purpose, the transmitting and receiving device of the mobile terminal and / or the server establishes the communication connection with a transmitting and receiving device of a unit providing the identification data and receives the identification data from the unit via the communication connection. The unit can, for example, comprise a server-internal or external database system that stores the identification data of the vehicle to be identified and / or transmits it via the communication connection upon request.Based on the transmitted identification data, the vehicle can be uniquely identified as the vehicle to be identified. For this purpose, the identification data can include or describe one or more characteristics that characterize the vehicle. For example, a user receives the identification data of the vehicle booked via an application (app) from the brokerage service provider (e.g., Uber™) on their mobile phone, making it possible to identify the vehicle from a multitude of vehicles based on the identification data.

[0016] Now an automated detection of at least one object actually present in the environment can take place in order to be able to check for the at least one detected object using the identification data whether it is the vehicle to be identified.

[0017] Firstly, object recognition can be carried out on the basis of environmental data. The environment is recorded by the recording device to generate the environmental data. In this case, the environment of the mobile device and / or the server is recorded, i.e. recorded, for example, using sensors using a camera in the recording device. On the basis of the recorded environmental data, the at least one object is recognised by the evaluation device. The evaluation device is in particular a computing device. For example, the environment of the user who wants to identify the vehicle they have booked is recorded using the mobile phone camera. In order to recognise the at least one object, the evaluation device checks whether the environmental data match the stored or filed recognition data of the at least one object.The stored recognition data therefore describes at least one possible object that can be recognized by the evaluation device. The recognition can be carried out, for example, using an artificial neural network trained for recognition. The recognition data can then comprise the configuration data of the neural network. For object recognition, the environmental data is compared with the stored recognition data of the at least one object. The stored recognition data are, in particular, stored features of the at least one object, based on which the at least one object is recognized as an object of a specific object type, for example, as a vehicle. The recognition data is retrieved, for example, from a storage device of the mobile device and / or the server.During the verification, the focus is on assignment, i.e., classification, rather than a unique, individual identification of the at least one object. Based on the environmental data, the at least one object is recognized, for example, only by its object type (e.g., as a vehicle). For example, the at least one object in the environment is determined to be a stationary object, such as an infrastructure facility (e.g., a building or a traffic route), a geographical object (e.g., vegetation or geology), or a mobile object (e.g., a vehicle or a living being).

[0018] If the environmental data matches the stored detection data, i.e., at least one object in the environment was detected, object data is generated that characterizes the at least one object and is extracted from the recorded environmental data by the evaluation device. This allows the object data to represent a subset of the recorded environmental data. Thus, object data is only available for at least one object that is potentially considered the vehicle to be identified.

[0019] Now it is necessary to check whether the vehicle to be identified is located beneath the at least one detected object. The evaluation device checks whether the object data of the at least one detected object match the vehicle's identification data. Thus, the features of the at least one object extracted from the environmental data are compared with the transmitted features characterizing the vehicle to be identified. For example, it is detected that the at least one object and the vehicle to be identified at least partially match in their shape and / or position and / or a marking.

[0020] If the object data matches the identification data, at least one display symbol is generated that characterizes the identified vehicle. The object data preferably matches the identification data in such a way that a matching criterion, for example, a minimum percentage match of the respective data, is met. If the vehicle can be identified based on the match, i.e., can be clearly recognized as the vehicle to be identified, then at least one display symbol, for example, the graphic element, is generated, i.e., provided.

[0021] The display device of the mobile device displays at least one display symbol of the identified vehicle and the surroundings. The display device is, for example, a screen of the mobile device which outputs the at least one display symbol and the surroundings data. When displaying the surroundings, the at least one display symbol is superimposed on the at least one detected object. For example, the user is shown a virtual view of the surroundings via the screen of their mobile phone, wherein, by means of an augmented reality image, the at least one display symbol at least partially obscures a sub-area of ​​the surroundings which is associated with the at least one detected object. For example, the display of the surroundings shows several parked vehicles, wherein the identified vehicle is one of the vehicles.In order to display the identified vehicle to the user, at least one display symbol is superimposed on the virtually displayed environment so that the identified vehicle stands out visually from the surroundings in the display.

[0022] An advantage of the method according to the invention is that the identified vehicle is displayed to the user in a particularly easy-to-recognize manner using the representation of the surroundings explained above. At least one display symbol indicating the identified vehicle is inserted into the representation of the surroundings. By means of the at least one display symbol, the identified vehicle is optically marked and / or optically highlighted from the displayed surroundings, visible from the outside. The method according to the invention can be used for any type of vehicle handover that requires the identification of the vehicle. An advantage is that devices of the motor vehicle, such as a sensor device of the motor vehicle, can be dispensed with.The method according to the invention can be used, if necessary, by means of the mobile terminal for displaying the representation and other devices of the mobile terminal, in particular the mobile phone, and / or the server.

[0023] It is further provided that, by means of a detected relative movement of the mobile device in relation to the vehicle, the representation of the surroundings is corrected depending on the detected relative movement. The relative movement of the mobile device is determined, for example, by a sensor device such as a yaw rate sensor of the mobile device and / or transmitted coordinates of the mobile device and is evaluated taking into account transmitted vehicle coordinates. Based on this evaluation, the representation of the surroundings is adjusted. For example, the user tilts, i.e. moves the mobile device, so that a different section of the surroundings is detected. The representation of the surroundings must be changed accordingly so that deviations caused by the relative movement of the mobile device are compensated.An advantage is that the mobile device can be relocated by the user, with the display of the surroundings being adjusted to the relative movement. This allows the user to move freely while using the mobile device to view the identified vehicle.

[0024] The invention is based on the finding that, particularly in an environment comprising multiple vehicles and / or multiple objects, the search for a specific vehicle, i.e., the vehicle to be identified, is challenging, since recognizing the respective features of the vehicle to be identified is difficult due to overlap and / or distraction. Thus, the identification, i.e., the search for the vehicle to be identified, is supported by a direct transmission (live image) from the camera of the mobile device, with at least one display symbol marking the vehicle within a real camera image.

[0025] The invention also includes further developments which result in additional advantages.

[0026] One embodiment provides that the transmitted vehicle identification data comprise at least one of the following identification features: vehicle coordinates, such as a vehicle position and / or a vehicle orientation; a vehicle number, such as a vehicle license plate number and / or a vehicle key number (vehicle key number or KBA number); a vehicle symbol, such as a machine-readable one- or multi-dimensional code, for example a QR code (quick response code); a vehicle signal, such as a radiation signature of a radio communication device (transponder); a vehicle feature, such as a shape, a color, a vehicle type, and / or a specific vehicle component. The vehicle can be uniquely recognized, i.e., identified, based on at least one of the identification features.This can counteract the risk of confusion with another vehicle, especially if the vehicle to be identified and the other vehicle appear visually similar. For example, a sticker on the exterior of the vehicle bearing the vehicle-specific QR code can be used to identify the motor vehicle if the environmental data of the detected area includes the detected QR code.

[0027] A further embodiment provides that, when detecting the environment, coordinates of the mobile terminal are detected by means of the detection device and / or a navigation system. The detection device is designed to detect, for example, a distance, an angle, a direction, an altitude and / or a rotation rate. The navigation system is based in particular on a global navigation satellite system (GNSS) for determining positions, for example NAVSTAR GPS, GLONASS, Galileo or Beidou. Based on the detected coordinates, a position, i.e. a location and / or an attitude, i.e. a spatial orientation, of the mobile terminal in relation to the environment and / or the vehicle can be determined. This means that the position and / or attitude of the mobile terminal relative to the environment and / or the vehicle is detected.It is advantageous that the coordinates can be used to determine a current state and / or a change in state of the mobile device within a spatial reference system based on a historical state and the current state. For example, a distance traveled by a user can be determined based on a historical position and a current position.

[0028] A further embodiment provides that a distance to a transmitted vehicle position and / or a position difference to a transmitted vehicle position is determined using the detected coordinates of the mobile device. This can be calculated using vector subtraction. Depending on the determined distance and / or the determined position difference, additional information is output when displaying the surroundings. This means that the additional information is displayed in addition to at least one display symbol. For example, the additional information includes the distance still to be covered between a current user position, determined based on the position of the mobile device, and the transmitted vehicle position. It is advantageous that the display of the surroundings and the at least one overlaid display symbol is specified or supplemented based on the displayed additional information.This makes it particularly easy for the user to assess the information provided.

[0029] A further embodiment provides that the representation of the surroundings is provided from a perspective of the mobile device. In this case, the surroundings of the mobile device are output virtually in such a way that the representation of the surroundings is provided to the user in particular so that it is congruent with the actual surroundings. As a result, the representation of the surroundings is particularly advantageously integrated into the environment and can be captured, i.e. perceived, by the user as part of the environment. Since the representation of the surroundings visually merges into the actual environment at its boundary, particularly reliable identification of the vehicle within the displayed environment is provided. It is not necessary for the user to mentally convert, for example, the representation of the surroundings from a bird's eye view, as with a conventional road map, into a user perspective.

[0030] A further embodiment provides that the at least one display symbol is partially transparent and / or displayed in a signal color. The at least one partially transparent display symbol thus incompletely overlays the representation of the surroundings, so that the surroundings optically located behind the at least one display symbol remain visible through the at least one display symbol. This prevents, for example, a possible loss of information caused by complete concealment and / or counteracts irritation of the user due to the representation. The signal color is, in particular, a visually striking color in relation to the surroundings, i.e., a different color and / or a color associated with a specific information content, for example, green is associated with a match.This means that at least one detected object that identifies the vehicle is visually highlighted, i.e., marked, in the representation of the surroundings. Advantageously, the at least one such display symbol clearly indicates the identified vehicle within the representation of the surroundings.

[0031] A further embodiment provides that the display of the identified vehicle is carried out following a completed vehicle selection process or during the selection process using the mobile device. The selection process is, for example, a booking of the motor vehicle for passenger transport, wherein the motor vehicle is operated by the user and / or by another user (for example a driver) and / or autonomously. For example, the vehicle is displayed after the completed selection process, in particular after a rental agreement entered into by the user at an earlier point in time. In contrast, when the selection process is carried out in connection with the brokerage service provider that connects the user with a rented and / or private vehicle with a driver, such as Uber™, Didi™, Lyft™, MOIA™ or other taxi concepts, the vehicle is issued to the user, in particular during the selection process.The mobile device transmits at least one user input and / or receives at least one user output via the communication connection. For example, the at least one user input is a request to book a motor vehicle, with the request being confirmed to the user by means of the at least one user output and the identity data of the motor vehicle being transmitted. Alternatively or additionally, the selection process can also be used in the context of using a shared vehicle (car sharing). The advantage is that the selection process allows user-specific requests to be easily taken into account, allowing the user to select the vehicle according to their mobility requirements.

[0032] Furthermore, the invention provides a mobile terminal for displaying an identified vehicle in an environment, wherein the mobile terminal has a control device configured to carry out an embodiment of the method according to the invention. The control device for carrying out the method according to the invention comprises a processor unit which, for this purpose, has at least one microprocessor and / or at least one microcontroller and / or at least one FPGA (Field Programmable Gate Array) and / or at least one DSP (Digital Signal Processor). Furthermore, the processor unit can have program code configured to carry out the embodiment of the method according to the invention when executed by the processor unit. The program code can be stored in a data memory of the processor unit.

[0033] The invention also includes further developments of the mobile terminal according to the invention that have features already described in connection with the further developments of the method according to the invention. For this reason, the corresponding further developments of the mobile terminal according to the invention are not described again here.

[0034] The vehicle to be identified is preferably configured as a motor vehicle, in particular a car, for example a passenger car or truck, or as a passenger bus or motorcycle. Furthermore, the vehicle can comprise a non-powered vehicle, such as a bicycle.

[0035] The invention also includes combinations of the features of the described embodiments.

[0036] Exemplary embodiments of the invention are described below. Shown are: Fig. 1 a display of an identified vehicle using a mobile device; and Fig. 2 schematically shows a sequence of a method for displaying the identified vehicle in an environment.

[0037] The exemplary embodiments explained below are preferred embodiments of the invention. In the exemplary embodiments, the described components of the embodiments each represent individual features of the invention that can be considered independently of one another, each of which also develops the invention independently of one another. Therefore, the disclosure is intended to encompass combinations of the features of the embodiments other than those shown. Furthermore, the described embodiments can also be supplemented by further features of the invention already described.

[0038] In the figures, the same reference symbols designate elements with the same function.

[0039] The one in Fig. The exemplary embodiment shown in Figure 1 may be based on the following situation. Several vehicles 10 designed as passenger vehicles are arranged one behind the other in the direction of travel on a traffic area in an environment 12, wherein one of the vehicles 10 is a vehicle 14 to be identified. A schematic sequence of a method for displaying the identified vehicle 14, explained below, may Fig. 2 can be taken.

[0040] A user selects the vehicle 14 to be identified by means of a selection process in a preparatory step S0 of the method. A communication connection 16 is established between the mobile terminal 18, which in this case is a user's mobile phone, and a server 20 of a brokerage service, such as a cloud server, by means of respective transmitting and receiving devices 22 for mutual data exchange. If the user books the vehicle 14 by means of a user input 24 via an application (app) on their mobile terminal 18, the user input 24 is transmitted to the server 20 via the communication connection 16. In response, the server (20) can transmit a confirmation of the booking as a user output 26, which is received by the receiving device 22 of the mobile terminal 18 via the communication connection 16.

[0041] In a first step S1 of the method, i.e., following the selection process for the vehicle 14 or during the selection process, identification data 28 for identifying the selected vehicle 14 are transmitted via the communication connection 16 and received by the receiving device 22. The identification data 28 comprise at least one of the following identification features: vehicle coordinates 30, 32, such as a vehicle position 30 and a vehicle orientation 32; a vehicle number, such as a vehicle license plate number; a vehicle symbol 34, such as an adhesive QR code or an identifying image; a vehicle signal, such as a radiation signature; and a vehicle feature, such as a shape, a contour, a vehicle color, a vehicle type, a vehicle brand, or a specific vehicle component.

[0042] In a second step S2 of the method, the environment 12 is captured by means of a capture device 36, such as a camera of the mobile terminal 18, and based on the captured environment 12, an evaluation device 38, such as a computing unit, generates environment data 40. For this purpose, the user can swivel the terminal 18 around the environment 12.

[0043] In the subsequent third step S3 of the method, the evaluation device 38 checks whether the transmitted environmental data 40 matches stored recognition data 42 of at least one object 44. The recognition data 42 are transmitted from a storage device of the server 20 via the communication connection 16 to the evaluation device 38 of the mobile terminal 18.

[0044] If the environmental data 40 matches the stored recognition data 42, object data 46 are generated in a fourth step S4 of the method. The object data 46 characterize the at least one recognized object 44 and are extracted from the acquired environmental data 40.

[0045] In a fifth step S5 of the method, the evaluation device 38 checks whether the object data 46 of the at least one object 44 match the identification data 28 of the vehicle 14.

[0046] If a match is found, in a sixth step S6 of the method, the at least one display symbol 48 is generated which characterizes the identified vehicle 14.

[0047] Finally, in a seventh step S7 of the method, the surroundings 12 and the at least one hatched display symbol 48 of the identified vehicle 14 are displayed by means of a display device 50 of the mobile terminal 18, designed as a screen of the mobile phone. When the surroundings 12 are displayed, the at least one display symbol 48 is superimposed on the at least one detected object 44.

[0048] All in Fig. 1 and Fig. The devices 22, 36, 38, 50 shown in FIG. 2 and assigned to the mobile terminal 18 are controlled by a processor unit of a control device 52 of the mobile terminal 18 to carry out the method. All devices 22, 36, 38, 52—except for the display device 50—of the mobile terminal 18 can also be assigned to the server 20. Alternatively, the devices 22 assigned to the server 20 can be assigned to the mobile terminal 18.

[0049] To display the identified vehicle 14 in the environment 12, the at least one display symbol 48 characterizing the identified vehicle 14 is partially transparent and output in a signal color in order to highlight the at least one object 44 recognized as the vehicle 14 in the representation of the environment 12. The at least one display symbol 48 is displayed in the representation of the environment 12 such that the virtually displayed environment 12 and the actual environment 12 correspond to one another and are provided from a perspective of the mobile terminal 18. Thus, the at least one display symbol 48 is only visible if the representation of the environment 12 also includes the identified vehicle 14.The representation and / or the perspective is determined or corrected, for example, based on detected coordinates 56, 58 and / or a detected relative movement of the mobile terminal 18 in relation to the environment 12 and / or the vehicle 14.

[0050] When detecting the environment 12, the coordinates 56, 58 of the mobile terminal 18 are detected by the detection device 36, such as a magnetic or laser-based sensor unit. Alternatively, the coordinates 56, 58 can also be determined using a navigation system (not shown). The detected coordinates 56, 58 include a position 56 and an orientation 58 of the mobile terminal 18 relative to the environment 12 and the vehicle 14. Using the transmitted vehicle coordinates 30, 32, i.e., the vehicle position 30 and the vehicle orientation 32, a distance and / or a position difference is determined, which is output as additional information 60 when displaying the environment 12.

[0051] The user can then clearly distinguish the vehicle 14 he has selected from the remaining vehicles 10 in the vicinity of the vehicle position 30 based on the representation of the surroundings 12 displayed on the mobile terminal 18 and the at least one displayed display symbol 48.

[0052] The invention is based on the finding that a user's mobility is individualized by means of various brokerage services, such as Uber, Didi, Lift, Moia, or other taxi concepts. This type of mobility is also referred to as ride-hailing, i.e., requesting a driving service. The driving service is requested using an application (app) offered on the mobile phone, i.e., the mobile terminal 18, by means of which the vehicle 14 is booked. After the booking, the vehicle 14 drives to the user, or the user moves to the displayed vehicle position 30, i.e., a stopping position of the vehicle 14. If there are several vehicles 10 in the vicinity of the vehicle position 30, it is not clear to the user which of the vehicles 10 is the booked vehicle 14.

[0053] By displaying the surroundings 12 in conjunction with an augmented reality image, the vehicle 14 sought by the user can be identified. For this purpose, the user scans the vehicles 10 using the detection device 36 of the mobile terminal 18, i.e., the camera of their mobile phone. The booked and identified vehicle 14 is optically marked or highlighted by the display device 50 of the mobile terminal 18, i.e., the screen (display) of their mobile phone, using at least one display symbol 48.

[0054] The procedure can also be used for picking up the vehicle 14 as part of a rental car pick-up at a rental car station or for other vehicle pick-ups.

[0055] Overall, the examples show how the invention can provide an assisted search of the identified vehicle 14, particularly in ride-hailing.
