Description

TECHNICAL FIELD

[0001] The invention relates to a method and a device for presenting information to a driver of a motor vehicle and to a motor vehicle. BACKGROUND

[0002] In modern vehicles, a large number of information can be provided to the driver. However, this information is difficult to recognize and can distract from the normal driving operation. There is also information which is difficult or even impossible for the driver to obtain without the aid of a third device, for example using a mobile phone. SUMMARY

[0003] It is therefore an object of the present invention to provide an improved method and an improved device for presenting information to a driver of a motor vehicle. In particular, it is an object of the present invention to achieve a better visualization of information for the driver.

[0004] This object is achieved by the subject matter of the independent claims. Advantageous improvements are given in the dependent claims.

[0005] According to a first aspect, a method for presenting information, in particular driving information, to a driver of a motor vehicle is provided. Herein, the method comprises the steps of: acquiring a control operation of the driver on the motor vehicle; determining driving information for the driver based on the control operation; and displaying the driving information on a portable display device of the driver.

[0006] The method of the present invention serves to visualize driving information for a driver of a motor vehicle. Herein, the driver is in particular seated on a driver's seat of the motor vehicle and wears a display device. The display device can be an apparatus designed to display elements of a real world, that is to say reality, together with elements of a virtual world, that is to say virtual reality. In particular, the display device is a pair of glasses worn on the bridge of the nose and / or in front of the eyes of the driver. Alternatively, the display device can also be an apparatus, for example a visor or a visor, fixed on a headgear, in particular a helmet, such as a jet helmet or a full-face helmet, of the driver. In the worn state, at least a part of the display device is then arranged in front of the eyes of the driver in such a way that the driver can see the elements displayed on the display device, in particular the driving information described below.

[0007] The display device can be designed, inter alia, as a device for presenting a virtual reality (VR, English, virtual reality) to the wearer of the display device, i.e. the driver. Virtual reality here means presenting reality that is at least partially filled by images of things that are not present in the surroundings of the occupant, such as objects or panoramas, in a visual manner. In particular, the method serves to merge parts of the actual reality, for example in the external space around the motor vehicle and in the vehicle interior of the motor vehicle, with virtual reality. Reality can also be referred to as augmented reality (AR, English, augmented reality), augmented virtual reality (AV, English, augmented virtuality) and / or mixed reality (MR, English, mixed reality), or the method is designed to present not only virtual reality but also augmented reality, wherein the two terms are used synonymously in the following text unless stated otherwise.

[0008] In a first step of the method according to the application, a control operation of the driver on the motor vehicle is acquired or determined. The control operation is in particular an operation on a motor vehicle control element, such as a steering wheel, an accelerator pedal and / or a brake pedal. In particular, the control operation is a steering, acceleration and / or braking, or an operation on a motor vehicle device that causes a steering, acceleration and / or braking to occur. To this end, the motor vehicle can have suitable sensors that can acquire such an operation, such as a steering wheel sensor, in particular a steering wheel angle sensor, an accelerator pedal sensor and / or a brake pedal sensor.

[0009] In a further step of the method according to the application, driving information provided for the driver is determined or calculated on the basis of the control operation.

[0010] This determination can be made, inter alia, by means of a processor device that accesses one or more sensors. This can be implemented in a wired manner or in a wireless manner. For example, on the basis of an excessively operated accelerator pedal or an excessively steered, it can be determined to issue a warning to the driver. Alternatively or additionally, a specific location in the vehicle surroundings can be prompted to the driver.

[0011] In a further step of the method according to the application, the previously determined driving information is displayed on a portable display device of the driver. To this end, the processor device, inter alia, accesses the display device or provides the display device with the data required for this purpose. This can be implemented in a wired manner or in a wireless manner.

[0012] In particular, the driving information can be displayed in the form of a so-called virtual avatar. A virtual avatar is a realistic or near-realistic virtual representation, for example in the form of a human or humanoid representation and / or in the form of a car, in particular a motor vehicle, which the driver is driving.

[0013] In particular, the virtual avatar in the form of a human can display gestures and / or hand signals to the driver. Here, the virtual avatar can be shown in a photo-realistic or near-realistic manner or, alternatively, as a comic or fantasy character. Furthermore, the virtual avatar in the form of a car, in particular, can drive ahead of the driving route of the motor vehicle. Additionally or alternatively, the driving information can also contain displayed text, which will also be described in the following.

[0014] By means of the method according to the application, it is achieved that important information is displayed to the driver during driving without distracting the driver's attention, while the information is presented in a social manner familiar to the driver or human. In particular, by using a virtual avatar, it is achieved that the driving information is compiled and displayed in a particularly vivid, intuitive and easy-to-understand manner.

[0015] According to an improvement, the method further comprises acquiring a navigation destination of the motor vehicle, wherein the driving information is determined additionally based on the navigation destination.

[0016] Here, the navigation destination is an address, for example a road and a house number, coordinates, a point of interest (English, POI, point of interest) and / or a basic orientation.

[0017] In particular, the acquisition can be carried out by user input, which will also be described in more detail in the following. Alternatively, the acquisition can also be carried out by accessing a navigation system.

[0018] At this point, the driving information is determined additionally based on the previously acquired navigation destination of the motor vehicle. In particular, the driving information can be determined taking into account the control operation and the navigation destination and displayed to the driver. Thus, the virtual avatar can additionally show navigation instructions.

[0019] By means of this improvement, it is achieved that the driver's attention is not distracted even when navigating to the navigation destination and that the navigation destination is reached safely.

[0020] According to an improvement, the method further comprises acquiring a location of the motor vehicle, wherein the driving information is determined additionally based on the location.

[0021] The location comprises the current location of the motor vehicle and / or a range of a defined radius around the motor vehicle, for example 100 m, 500 m or 1000 m. This can be achieved by means of suitable positioning sensors, for example GPS sensors.

[0022] Alternatively or additionally, the location of the motor vehicle comprises a future location of the motor vehicle, for example a location on the route to the navigation destination and / or a location to be reached in future on the basis of road guidance. This can be derived from the navigation system of the motor vehicle and / or from stored map data, in particular also using GPS sensors.

[0023] At this point, the driving information is additionally determined on the basis of the previously acquired location of the motor vehicle. In particular, the driving information can be determined taking into account the control operation and the location, and displayed to the driver. Thus, the virtual avatar can additionally provide POIs or points of interest on the route.

[0024] By means of this refinement, a particularly rich amount of information is achieved for the journey. In particular, it is thereby achieved that the driver is informed about important events along the navigation route.

[0025] According to one refinement, the method further comprises acquiring an acceleration of the motor vehicle, wherein the driving information is additionally determined on the basis of the acceleration.

[0026] The acceleration in particular comprises a longitudinal acceleration and / or a transverse acceleration or a resultant acceleration of the motor vehicle, and / or an acceleration vector resulting therefrom. For example, the acceleration comprises a longitudinal acceleration when driving straight and / or a transverse acceleration when turning. The acceleration can also take negative values, for example when driving at a deceleration.

[0027] Additionally or alternatively, the method can also acquire a speed and / or derive a speed from the acceleration.

[0028] Here, the acquisition is achieved by means of suitable sensors, for example acceleration sensors, one or more gyroscopes, in particular MEMS gyroscopes, and / or one or more inertial sensors. The acquisition of the acceleration can in particular also be achieved by means of sensors already present in the motor vehicle and / or derived from driving data.

[0029] The driving information is additionally determined on the basis of the previously acquired acceleration of the motor vehicle. In particular, the driving information can be determined taking into account the control operation and the acceleration, and displayed to the driver. Thus, the virtual avatar can additionally provide control operation instructions.

[0030] By means of this refinement, it is achieved that the driver is indicated in advance when a braking operation or a steering operation should be performed. In particular, it is thereby achieved that the driver is prompted about an excessively high acceleration or an excessively high speed, and guided to brake before a dangerous situation arises. This is particularly safe.

[0031] According to an improvement, the method further comprises obtaining a user input of the driver, wherein the driving information is displayed additionally based on the user input.

[0032] Here, the user input comprises an input of the driver on the motor vehicle or on an input device of the motor vehicle. Here, the user input is suitable for communicating information, in particular the wishes, needs and / or requests of the driver, to the motor vehicle or to the processor device. In particular, the user input is not a control operation of the driver on the motor vehicle, but rather a different input.

[0033] For example, the user input is an actuation of a specific button, key and / or switch. Alternatively or additionally, the user input is an input on a touch screen, in particular a selection of a virtual button displayed on the touch screen and / or a text input on a virtual keyboard displayed on the touch screen.

[0034] Alternatively or additionally, the user input is a voice input and / or a gesture. Here, the user input is not limited to the driver and / or the wearer of the display device, but rather also a passenger who does not wear the display device and / or a companion of the driver can input.

[0035] In particular, the user input is the navigation destination described above, or this can also be different. For example, the user input is a request to display a specific POI along the route.

[0036] Here, the driving information is displayed additionally based on the previously obtained user input. In particular, the driving information can be determined taking into account the control operation and the user input and displayed to the driver. Thus, the virtual avatar can additionally take into account the user's wishes when it is displayed.

[0037] Alternatively or additionally, the user input comprises a question to the virtual avatar, for example about the operation of a vehicle function, and the driving information contains an explanation of the virtual avatar about this function.

[0038] Furthermore, the user input comprises an operation of a function, in particular a comfort function of the vehicle, and the virtual avatar additionally visualizes the activation of this comfort function. For example, in the case of an operation of a heating device, the virtual avatar can change its color. In particular, by operating a vehicle function, an interaction with the virtual avatar can also be simulated. That is, for example, during the activation of a seat belt tensioner, the virtual avatar can virtually lunge at the driver, thereby pressing the driver against the seat.

[0039] With this improvement, a user feedback can be realized for the driver. In particular, the driver can interact with the virtual avatar by means of the user input, thus expressing his wishes and needs. Thus, a particularly interactive method can be realized.

[0040] According to an improvement, the method further comprises retrieving secondary information, wherein the driving information is determined additionally based on the secondary information.

[0041] Here, the secondary information is information related to the motor vehicle, the driver, the accompanying person and / or the motor vehicle's surroundings. In particular, the secondary information is information which is not stored in the motor vehicle and / or which is only retrieved on demand in specific situations. For example, the secondary information is extended information about a POI, such as opening hours, public ratings and / or free parking spaces.

[0042] Here, the retrieval can be implemented in particular by means of a communication device and / or a processor device of the motor vehicle, for example in accordance with a mobile communication standard (for example 3G, 4G or 5G) and / or a vehicle-to- everything communication standard.

[0043] Here, the driving information is determined additionally based on the previously retrieved secondary information. In particular, the driving information can be determined taking into account the control operation and the secondary information and displayed to the driver. Thus, the virtual avatar can additionally take into account the user's wishes when it is displayed.

[0044] By means of this improvement, it is possible to retrieve further information based on the user input, for example information about the navigation destination or information about the route along the way, and to display it to the driver. Thereby, a particularly rich amount of information of the method is achieved.

[0045] According to an improvement, the method further comprises acquiring the position of the driver, wherein the driving information is displayed additionally based on the position.

[0046] Here, the position of the driver in particular comprises the seat position. The seat position of the driver can be derived for example from a seat setting (for example a memory function) and / or calculated by a seat occupancy sensor (for example a weight sensor).

[0047] Alternatively or additionally, the position of the driver comprises a position in the vehicle interior, in particular relative to objects present in the vehicle interior (for example A-pillars, a windscreen, a steering wheel and / or interior mirrors). In particular, the position of the driver also comprises the position of the display device relative to these objects. For this purpose, one or more sensors, in particular image acquisition sensors, can be used in the vehicle interior of the motor vehicle and / or on the display device. For example, an infrared sensor on the interior mirror can recognize the driver, in particular his head, in an image and determine the position in the motor vehicle therefrom.

[0048] The driving information is thus additionally displayed on the basis of the previously acquired driver position. In particular, the driving information can be displayed to the driver taking into account the control operation and the driver position. The virtual avatar can thus be positioned particularly precisely on the display device for display. In particular, the virtual avatar can be positioned in such a way that it is displayed for the driver in a specific region, such as at the edge of the field of vision, in particular in such a way that it does not obstruct the road guidance.

[0049] By means of this refinement, it is possible to take into account the position, in particular the seat position, and thus the individual field of vision of the driver, so that a particularly safe, at the same time comfortable, display is possible.

[0050] According to one refinement, the method further comprises: acoustically reproducing the driving information.

[0051] Here, the acoustic reproduction can in particular be effected by means of loudspeakers in the vehicle interior and / or on the display device.

[0052] Here, the acoustic reproduction of the driving information can contain the same information as the displayed information or can contain different information from the displayed information. For example, the virtual avatar can display a hand signal for braking, while the request "stop" or "brake" is acoustically reproduced.

[0053] By means of this refinement, it is possible to either additionally redundantly inform the driver acoustically or to additionally inform the driver acoustically. It is thus possible to achieve particularly reliable and / or content-rich information.

[0054] According to another aspect, a method for presenting information for a driver of a motor vehicle is specified.

[0055] Here, the method comprises the following steps: acquiring the location of the driver; acquiring the location of the motor vehicle; determining the vehicle information provided for the driver on the basis of the acquired locations; and displaying the driving information on a portable display device of the driver.

[0056] This aspect, which will be described in more detail below, is in particular used for the driver to interact with the motor vehicle from the outside without staying in the motor vehicle. Furthermore, this aspect is in particular used for interacting with the motor vehicle without acquiring the control operation of the driver. The aspect can be carried out after the method aspect described above and can be carried out before and / or during the method.

[0057] Here, the acquisition of the location of the motor vehicle can be realized by suitable sensors as previously described. Likewise, the acquisition of the location of the driver can be realized by suitable sensors, for example by a GPS sensor installed in the portable display device or a further device coupled with the display device and / or the motor vehicle, for example a smartphone. It is also possible to acquire the orientation of the driver relative to the motor vehicle, for example by wireless communication (for example Wifi, Bluetooth or NFC). Thereby, it is also possible to carry out a communication of the portable display device with the motor vehicle, for example by transferring the vehicle information of the motor vehicle described hereinafter from the motor vehicle to the portable display device.

[0058] Subsequently, the vehicle information provided for the driver is determined on the basis of the two acquired locations and displayed to the driver on the portable display device.

[0059] The vehicle information can be in particular the location of the motor vehicle. The vehicle information can then contain the distance to the motor vehicle and / or the basic orientation relative to the motor vehicle. In addition, the vehicle information can also contain further information about the motor vehicle, for example the license plate number of the motor vehicle, the color and / or the model of the motor vehicle. The vehicle information can also contain information about the surroundings of the motor vehicle, for example images, objects or landmarks in the vicinity of the motor vehicle. In particular, the vehicle information can also contain information about the parking space of the motor vehicle, like for example the name and location of the parking lot, the floor, the parking space number or the parking area.

[0060] The display of the vehicle information can be in particular at least partially or completely in the form of a so-called virtual avatar, as has already been described previously. In particular, the virtual avatar can be designed to guide the path to the motor vehicle, wherein the virtual avatar is displayed on the portable display device such that the virtual avatar walks in front of the driver and turns into the correct road, alley or parking area on the path to the motor vehicle, thereby guiding the driver to the motor vehicle. Alternatively or additionally, the virtual avatar can be displayed such that it is located at and / or on the vehicle and / or the motor vehicle is highlighted in color or other graphical manner on the portable display device. In particular, the virtual avatar can be displayed such that it interacts with the driver, for example by waving or making a guiding gesture to the driver, whereby the location of the motor vehicle and how to find the motor vehicle can be indicated.

[0061] In particular, the acquisition of the specific location of the driver and / or the specific distance of the driver from the motor vehicle can trigger the method. For example, the method recognizes that the driver approaches the vehicle and / or enters the parking lot in which the motor vehicle is located. In particular, the determination of the vehicle information can be carried out as a response to the acquisition of the specific location of the driver.

[0062] It is thus made easier for the driver to find the motor vehicle. In particular in complex and / or large parking lots or city center areas, the driver can be safely and reliably guided to the motor vehicle. This is particularly useful in the case of a rental vehicle, where the driver only briefly sees the motor vehicle and does not remember the model, color and / or license plate number of the motor vehicle.

[0063] The method can be improved in that the method further comprises the step of acquiring a user input of the driver, wherein the driving information is displayed additionally based on the user input.

[0064] Here, the acquisition of the user input can take place as described above. In particular, the user input is a voice input and / or a gesture, which is acquired and processed, for example, by the portable display device.

[0065] In particular, the user input can comprise a question to the virtual avatar, for example, regarding the operation of a vehicle function, and the driving information contains an explanation of the virtual avatar on this function, as has been described previously. In particular, the vehicle function can be a function relating to the exterior space of the motor vehicle, for example, opening a filler cap, opening a charging port cover and / or opening a trunk.

[0066] Thereby, in particular in the case of a new car or a rental vehicle, one or more functions can be explained to the driver.

[0067] It goes without saying that these aspects can be combined with the aspects of the method described above and, in particular, can be carried out by the same device. In particular, these aspects can be carried out alternately and / or in a chronological order with the aspects of the method described above.

[0068] The method is in particular a computer-implemented method, which can be carried out partially or completely by a data processing device and / or one or more processor devices, which will also be explained below with reference to the device according to the application.

[0069] For application cases or application situations, which can occur in the method and are not explicitly described here, it can be provided that an error report is output and / or a user feedback is requested according to the method, and / or a default setting and / or a predetermined initial state is set.

[0070] According to another aspect, a device for presenting information for a driver of a motor vehicle is presented. The device, which can also be referred to as control device, can have a data processing device or processor device which is configured to carry out an embodiment of the method according to the invention. To this end, the processor device can have 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 device can have program code which is arranged, when being executed by the processor device, to carry out an embodiment of the method according to the invention. The program code can be stored in a data memory of the processor device. For example, the processor device can be based on at least one circuit board and / or at least one SoC (System on Chip).

[0071] In particular, the device can be a portable display device.

[0072] According to another aspect, a motor vehicle is presented which comprises such a device or control device.

[0073] Preferably, the motor vehicle according to the invention is designed as a car, in particular as a passenger car or a utility vehicle, or as a bus or a motorcycle.

[0074] As a further solution, the invention also comprises a computer-readable storage medium which comprises program code which, when being executed by a computer or computer group, carries out an embodiment of the method according to the invention. The storage medium can be provided at least partially as a non-volatile data memory, for example a flash memory and / or an SSD - solid state drive, and / or at least partially as a volatile data memory, for example a RAM - random access memory. The storage medium can be arranged in the computer or computer group. But the storage medium can also be operated on the internet, for example as a so-called APP store server and / or cloud server. By means of the computer or computer group, a processor circuit having, for example, at least one microprocessor can be provided. The program code can be provided as binary code and / or as assembly code and / or as source code of a programming language, for example C, and / or as a program script, for example Python.

[0075] The invention also comprises combinations of features of the described embodiments. Thus, the invention also comprises the following implementation scenarios, each having a combination of features of several of the described embodiments, as long as these embodiments are not described as mutually exclusive.

[0085] The embodiments explained below are preferred embodiments of the application. In the embodiments, the described individual parts of the embodiments are respectively single features of the application which can be considered independent of each other and which respectively improve the application independently of each other. The disclosure therefore also comprises combinations of features which differ from the shown combinations of features of the embodiments. Furthermore, the described embodiments can also be supplemented by other features of the application which have been described.

[0086] In the drawings, identical reference numerals respectively designate identical elements.

[0087] Figure 1A schematic flow chart illustrating one embodiment of a method 1000 for presenting driving assistance for a driver of a motor vehicle is shown.

[0088] The method 1000 starts with a first step 1010 in which a position of the driver is acquired. This step can also be referred to as an initial step and provides a basis for a particularly precise presentation.

[0089] The method 1000 continues with a further step 1020 in which a user input of the driver is acquired.

[0090] The method 1000 continues with a further step 1030 in which a location of the motor vehicle is acquired.

[0091] The method 1000 continues with a further step 1040 in which a navigation destination of the motor vehicle is acquired.

[0092] The method 1000 continues with a further step 1050 in which an acceleration of the motor vehicle is acquired.

[0093] The method 1000 continues with a further step 1060 in which secondary information is retrieved.

[0094] The method 1000 continues with a further step 1070 in which a control operation of the motor vehicle by the driver is acquired.

[0095] Here, the steps 1020 to 1070 can be referred to as acquisition steps and can in particular be executed repeatedly in a different order and / or periodically, in particular asynchronously. For example, the location and / or the control operation of the motor vehicle are acquired periodically, but the user input is acquired only as required and the navigation destination is acquired only once or when a change occurs.

[0096] The method 1000 continues with a further step 1080 in which driving information provided for the driver is determined on the basis of the acquisition steps.

[0097] The method 1000 continues with a further step 1090 in which the driving information previously obtained is displayed on a portable display device of the driver. Here, the display content can also take into account or be based on the acquisition content in the initial step 1010 and the user input in the step 1020.

[0098] The method 1000 continues with a further step 1100 in which the driving information previously obtained is also reproduced acoustically.

[0099] The method 1000 ends with the step 1100 and can be started again if necessary.

[0100] The method 1000 ends with the step 1100 and can be started again if necessary. Figures 2 to 7An apparatus is shown which is designed, inter alia, to carry out the method described in connection with Figure 1 It goes without saying that the embodiments shown in the following Figures 2 to 7 may exist side by side, or be carried out or realized simultaneously and / or successively by the same apparatus.

[0101] Figure 2 A schematic diagram of an embodiment of an apparatus 100 for presenting driving assistance to a driver of a motor vehicle 1 is shown.

[0102] For the sake of clarity, the driver is not shown in Figure 2 sitting on a driver's seat 2 and observing through a portable display device 110, which is part of the apparatus 100. The display device 110 is currently designed as an augmented reality display device, which comprises partially or completely light-transmissive mirrors 111 and 112 through which the driver can see reality in the form of an interior space 3 of the motor vehicle 1 and an exterior space 4 of the motor vehicle.

[0103] Alternatively, the display device 110 can also be designed as a completely virtual display device, which comprises one or more image acquisition apparatuses which acquire parts of the interior space 3 and the exterior space 4 and present them to the driver through non-transparent mirrors.

[0104] Here, the apparatus 100 is designed to acquire a control operation of the driver on a steering wheel 5 of the motor vehicle 1, to determine driving information provided for the driver on the basis of the control operation and to display the driving information on the portable display device 110 of the driver.

[0105] It goes without saying that not only the driver, but also one or more accompanying persons can wear such a display device, which also receive the same information, in particular driving information, or different information.

[0106] In the embodiment shown in Figure 2 the driving information 10 is displayed in the form of a humanoid virtual avatar. This virtual avatar can move the arms, for example, and thus display driving information, such as acceleration, braking or steering operations, for example, such as a turn and / or a lane change, to the driver.

[0107] Figure 3 A schematic diagram of a further embodiment of an apparatus for presenting driving assistance to a driver of a motor vehicle is shown in Figure 2

[0108] At this point, as Figure 2 ​The embodiment shown in the illustration not only depicts a human or humanoid virtual avatar, but also additional information, particularly secondary information, that has been remotely retrieved from a location far from the vehicle 1. Here, the secondary information is exemplarily displayed as a speech bubble, but alternatively or additionally, it can be played back acoustically on a speaker in the vehicle's interior space 3.

[0109] Here, secondary information is based on the vehicle's current location and the planned navigation destination. Therefore, secondary information includes recommendations for restaurants located near the navigation destination and / or along the route to the navigation destination.

[0110] In addition to the name and address, more information, such as reviews, can be displayed at this point. Specifically, secondary information can be retrieved and displayed based on user input from the driver or front passenger, such as displaying nearby highly-rated restaurants based on voice data.

[0111] and Figure 2 The implementation shown differs, in which a humanoid virtual avatar is displayed outside vehicle 1, and is specifically displayed such that the virtual avatar has the same height and / or position as a person in the real external world 4. Therefore, the virtual avatar is specifically displayed such that it is located on the roadside and / or not in the lane for motor vehicles.

[0112] Figure 4 It shows Figure 3 A schematic diagram of another embodiment of a device for demonstrating driving assistance to drivers of motor vehicles.

[0113] At this time, as Figure 3 The additional embodiment shown not only depicts a human or humanoid virtual avatar and primary information in the form of speech bubbles, but also additional secondary information in the form of an oversized beverage bottle.

[0114] In particular, the beverage bottle can be displayed based on user behavior, especially if the driver has previously searched for or mentioned this type of soda. Alternatively or additionally, the possibility of purchase can be offered at the real-world location where the beverage bottle is displayed. Additionally, virtual avatar speech bubbles or acoustic reproduction can also prompt for this type of soda.

[0115] Figure 5 It shows Figure 4 A schematic diagram of another embodiment of a device for demonstrating driving assistance to drivers of motor vehicles.

[0116] and Figure 4In contrast to the embodiment shown in Fig. 1, here the virtual avatar of the motor vehicle is shown to the driver together with a navigation guide as driving information. In particular, the driving information indicates a free parking space available to the motor vehicle in the vicinity of the navigation destination of the vehicle.

[0117] In particular, the free parking space can be recognized by means of an image recognition algorithm.
