Abstract

The present invention discloses a motor vehicle operating device. It comprises, in a first embodiment, a head unit, one or more augmented reality goggles having at least one display and operatively connected to the head unit. Furthermore, the motor vehicle operating device has a viewing direction sensor which is provided for detecting head movements and which is a position sensor arranged on the augmented reality glasses. Furthermore, a motor vehicle with the motor vehicle operating device according to the invention and a motor vehicle operating method are disclosed.

Description

  • The invention relates to a motor vehicle operating device, a motor vehicle having such a motor vehicle operating device and a motor vehicle operating method.
  • The amount of information that can now be presented to the driver of a motor vehicle, comes to the limits or exceeds the possibilities of conventional display concepts. In addition to the strictly vehicle-related information, the rigorous upgrading of the sensors together with the increased functionality (safety, assistance and comfort systems) has increased the amount of information that has to be conveyed. At the same time, the desire to provide the driver with as much information as possible without distraction from the traffic is higher than ever. In addition to vehicle-related warnings also short messages, mails and information from social networks can be displayed. In addition to classic display instruments, displays in the instrument cluster and / or in the center console can already be used to display multimedia presentations and configure the displays in a user-specific manner. Here, however, both the display positioning and the display size are linked to strong boundary conditions in terms of design and space. Especially dedicated systems, which rely on large and high-resolution displays, often can not be implemented as would be desirable for optimal user interaction. Therefore, it has been proposed to use head-mounted displays for displaying information in the motor vehicle. In particular, so-called augmented reality glasses are advantageous, which allow the simultaneous perception of a display content and reality.
  • So concerns the EP 1 990 674 A1 a head-mounted display system, which is intended in particular for use in motor vehicles and has as a central component display glasses. The motor vehicle has outside area sensors connected to a data processing device. The display glasses are communicatively connected to the data processing unit, with data from the outdoor sensors being displayed in the display glasses. In addition, the view can be overlaid with vehicle information, for example about the oil level, engine temperature and / or the current speed. In addition, a viewing direction sensor can be fixedly arranged on the motor vehicle, with which larger head movements can be detected. On the glasses, another viewing direction sensor can be arranged, which detects eye movements of the user. The viewing direction data can be used to display different information in the display depending on the viewing direction.
  • Based on this prior art, it is an object of the present invention to improve the eye caused by changing the direction of the user operating the motor vehicle without or provide as little as possible installations in the vehicle interior.
  • This object is achieved by means of a motor vehicle operating device having the features of claim 1.
  • Furthermore, the task results to create a motor vehicle that can be operated optimally and without disturbing the driver by changing the gaze direction of the user.
  • This object is achieved by a motor vehicle having the features of claim 3.
  • Finally, there is the object of providing a motor vehicle operating method which makes it possible to operate such a motor vehicle more intuitively than before.
  • This object is achieved by a motor vehicle operating method with the features of claim 5.
  • Further developments of the devices and the method are each carried out in the subclaims.
  • The motor vehicle operating device according to the invention comprises, in a first embodiment, a head unit, one or more augmented reality goggles having / having at least one display and being operatively connected to the head unit. Furthermore, the motor vehicle operating device has a viewing direction sensor which is provided for detecting head movements and which is a position sensor arranged on the augmented reality glasses.
  • The head unit is the data processing device of the infotainment system, in which sensor signals are processed and output signals are generated. For example, applications for navigation and / or the parking assistant are executed there. Within the meaning of the invention, the "augmented reality glasses" are to be understood as spectacles which have at least one display for displaying information and the position sensor which is suitable for detecting the relative position and the orientation or inclination of the spectacles in the vehicle , Such sensors are, for example, acceleration sensors and / or sensors whose position can be determined by radio positioning, the position of the spectacles then determined using multiple such sensors. In contrast to known motor vehicle operating device, which also know the operation with an augmented reality glasses, according to the invention for determining the position of the glasses no separate motor vehicle-bound position sensor, such as a mounted on the dashboard or in the mirror triangle camera necessary; the sensors are completely assigned to the glasses. Therefore, it is possible to install the motor vehicle operating device according to the invention very inconspicuously in the motor vehicle interior. Furthermore, it is also possible that not only the driver uses an augmented reality pair of glasses coupled with the head unit, but also, for example, passengers in the back seat. There, too, the position and inclination of the glasses can be advantageously detected, without the need for additional cameras or similar detection devices should be directed to the wearer glasses.
  • In a further embodiment of the motor vehicle operating device, the augmented reality glasses and the head unit can be communicatively connected to one another via a wireless connection, advantageously via a short-range radio connection or an optical connection. Alternatively or additionally, the display of the augmented reality glasses can be a semi-transparent display, in particular a semi-transparent display with a beam splitter. Furthermore, the augmented reality glasses may have at least one sound transducer, such as a microphone and / or a loudspeaker. Furthermore, a motor vehicle-bounded outside area sensor can be communicatively connected to the head unit, the outside area sensor advantageously being a camera, and a night-vision camera and / or a reversing camera being or being particularly advantageous.
  • In addition, the motor vehicle operating device can have an input device operatively connected to the head unit, wherein an input key, in particular a rotary-push-dial, is advantageous.
  • As used herein, "communicative connection" is intended to mean that the augmented reality goggles are advantageously coupled to the head unit for bidirectional data exchange. In particular, position and position data of the position sensor are transmitted to the head unit by the augmented reality glasses, while the glasses receive and reproduce display data and / or audio data. The term semitransparent display herein means that when viewing the display, the reality behind the display can still be perceived simultaneously. This can be done, for example, by a partially transparent LCD display, which is positioned directly in front of the eye, or by a beam splitter prism with which an image of, for example, arranged in a bracket of the glasses projector is reflected. For wireless data transmission from the augmented reality goggles to the head-unit and vice versa are joining techniques and protocols known as Bluetooth ® or Wi-Fi. A wireless connection is associated with special advantages, since no disruptive cables run in the interior and the appearance of the interior can be kept very tidy.
  • A motor vehicle according to the invention has, according to a first embodiment, a motor vehicle operating device according to the invention.
  • Advantageously, no additional cameras or other detection devices on the motor vehicle or in the motor vehicle interior must be arranged for detecting the position information of the augmented reality glasses, since the sensor system for this is completely integrated in the glasses. This makes it possible to make the interior inconspicuous; it does not occur that the motor vehicle is equipped with the motor vehicle operating device according to the invention.
  • In a further embodiment, the head unit can have an Internet connection and / or TV reception device. Alternatively or additionally, an autonomous driving device may be operatively coupled to the head unit.
  • The device for autonomous driving can be connected to the head unit, for example, for inputting desired data, such as a desired speed and / or a destination, and for outputting status and warning information, for example the transfer of control to the driver.
  • A first embodiment of the motor vehicle operating method is carried out using the motor vehicle according to the invention and comprises the steps:
    • Setting of a predetermined viewing direction and detection of motor vehicle relative viewing direction data by the position sensor of the augmented reality glasses,
    • Sending the gaze direction data from the augmented reality goggles to the head unit and processing the gaze direction data through the head unit;
    • - Sending a viewing direction data assigned predetermined display content from the head unit to the augmented reality glasses and displays on the display.
  • Advantageously, virtual contents or projection surfaces can be more intuitively noted by the method according to the invention than hitherto. Certain places in or on the motor vehicle display information is assigned to this. The user must, to perceive this information, as with conventional instruments, swing his gaze to this very position. This corresponds much more to the familiar interaction with instruments. The user behavior for acquaintance with conventional instruments is virtually transferred to the "virtual instruments" assigned to a specific location. There is a variety of display content conceivable that can be displayed when looking at very different places in or outside of the vehicle.
  • The display contents may be, for example, vehicle dynamics information, imaging data of the outside area sensor, vehicle information, tire information, a representation of a communication means, in particular an internet browser and / or a social networking application, a video and / or TV image display, a interactive maintenance instruction, preferably with instructions, act. In this case, in particular the view of a door, a door warning, the view of another road user distance warning, the view of a seat a seatbelt warning, the view in direction, direction information, speed information, range information, navigation information and / or image data of the indulgence camera, the view to the rear of the vehicle and / or a rear-view mirror image data of the outside area sensor, preferably imaging data of the rear view camera, the view of an energy filling connection an energy storage information, the view of the engine compartment engine information from the group comprising oil temperature, oil level, oil temperature, coolant level, coolant temperature, Betriebsflüssigkeitsnachfüllanleitung, the view on a tire a tire information, the view of a front seat and / or a headrest from a back seat from a video and / or TV image, the view of a wheel or the Koffe rraum be assigned a wheel change instructions.
  • The enumeration of the display contents is not conclusive, but more display content including other associated places are possible. Advantageously, it is possible by the method according to the invention, a motor vehicle that has no rearview mirror to operate as a conventional motor vehicle with rear-view mirrors. The mirror positions are each associated with imaging data of one or more reversing cameras. In order to further improve the orientation of the driver when using the rear view camera, the image can also be displayed in the area of the windshield, so that he has the impression that he was sitting backwards in the vehicle. The view in the direction of travel can be superimposed in the dark, the image of a pointing in the direction of travel night-vision camera and alternatively or additionally, a pedestrian warning system can be displayed. The method allows for improved safety by allowing the driver to operate the numerous assistance systems more intuitively, thereby making them more useful than with a conventional operating concept. However, the contents of the display are not limited to driving safety-relevant content, but passengers in the back seat, for example, can watch television and / or a video on a virtual display in the front seats or at a separation level to the front seat row. The display of specific maintenance instructions with step-by-step execution instructions is a very important display content, in particular due to the increasing complexity and the decreasing technical understanding of the users, which can even influence the purchase decision for a motor vehicle with the method according to the invention.
  • In yet another embodiment of the method, the display content may include only a subset of the imaging data of the exterior area sensor. The subset is selected as a function of the viewing direction data by the head unit from a total of the image data, wherein advantageously those image data are selected which show the part of the exterior, not visible from the position of the augmented reality glasses due to occlusion by a body component is.
  • The parts of the exterior, which are covered by the opaque body component, such as the columns, doors, etc., can not be viewed by the driver without tools. However, outside area sensors can "look" into these areas. The data of the outdoor sensors are now displayed in perspective correct in the display of the augmented reality glasses, so that the wearer of the glasses gives the impression that the vehicle is at least partially "transparent". As a result, a previously unattained all-round visibility is achieved, which allows even small children or recumbent drivers to easily recognize what the traffic safety, especially when driving in the city, significantly improved. However, a motor vehicle equipped with the method can also be much more aerodynamically optimized, since it is no longer necessary to pay so much attention to boundary conditions that are due to clarity.
  • In addition, the display content may include a navigable selection menu of the head unit. The menu navigation may be accomplished by executing one or more predetermined gestures, preferably nodding or turning the head, simultaneously acquiring the gaze direction data through the augmented reality gantry sensor and sending to the head unit. Alternatively, it is also possible to navigate through the menu by operating the input device.
  • Combinations of the input through the augmented reality goggles and the input device are also conceivable; for example, a drop-down menu can be scrolled with the aid of the augmented reality goggles while the selection is made by the input device. Such an operating concept makes it possible to achieve menu functions with significantly fewer actuations of the "hardware" input device than before, as a result of which the driving safety can be increased since the driver no longer has to take his hands from the steering wheel for operation. The list of gestures is not to be taken as conclusive, if it makes sense, for example, due to cultural differences, quite different gestures can be used.
  • Alternatively or additionally, a viewing direction-independent display content can be sent from the head unit to the augmented reality glasses and displayed on the display. In this case, the viewing direction-independent display content advantageously comprises warning information, particularly advantageously information associated with the device for autonomous driving.
  • The viewing direction independent display content can be displayed at any time on the augmented reality glasses, no matter which display content was displayed before that time. In particular, this function is important as a safety function, since always, even if the driver is watching television through the augmented reality glasses while the vehicle is driving autonomously, an error can occur, which must be communicated immediately. This warning information can overlay or completely displace the current display content. The display is independent of the tilt and position of the glasses, so that the wearer perceives the warning stationary, which makes it difficult for him to ignore them. In particular, this is true when the autonomous driving device gives the vehicle control back to the driver; In this case, as stationary display content, for example, a countdown to be displayed until the handover.
  • According to another embodiment, a display content configuration method may be performed within the vehicle operation method. It has the following steps:
    • Selecting a display content to be assigned to the viewing direction by the head unit,
    • Adjusting the viewing direction, detecting the viewing direction data by the position sensor and sending to the head unit,
    • - Operating the input device or maintaining the viewing direction for a predetermined period of time, thereby assigning the gaze direction data to the display content and storing the assignment in the head unit.
  • Using the display content configuration method, it is possible to personalize the virtual projection surfaces of the control concept. According to his preferences, the driver can position certain display contents at any vehicle positions, for example he can position the representation of means of communication, such as an internet browser, a mailing service or any other apps, on the area of the passenger seat, so that from his driver's seat, as it were, a "rolling office" can be operated intuitively and comfortably. Of course, the selection of the display content to be assigned can also be done by the input device. However, it can not only be provided to configure the display contents and associated positions, but it is also possible to individually determine the gestures to be recognized for input.
  • These and other advantages will be set forth by the following description with reference to the accompanying figure.
  • The reference to the figure in the description is to aid in the description and understanding of the subject matter. The figure is merely a schematic representation of an embodiment of the invention.
  • The sole figure shows a motor vehicle cockpit from the perspective of a vehicle user wearing the coupled with the head unit of the vehicle augmented reality glasses. The glasses has a position sensor, with which it is always possible to determine relative to the vehicle, the viewing direction of the wearer and to send to the head unit. Depending on the direction in which the wearer is looking, the head unit transmits another display content to the augmented reality glasses and displays it. For example, when looking at a position of the interior rearview mirror 1 Image data of a rearview camera in a virtual projection screen are displayed or when looking at a position of the exterior mirrors 2 Pictures of another or the same reversing camera in other virtual projection screens. According to the invention, the driver finds the known sources of information or instruments in the long-known places, although they are not physically present; they are merely virtual instruments or sources of information, but they are virtually assigned a fixed position. However, many more information can be displayed, for example, when looking at a seat 3 , are displayed as a superimposed representation, whether the seat belt is worn or not. The possibilities of the operating concept using the augmented reality glasses is not limited to the interior, but can also important information from the outside, such as the view be assigned to the filler neck a current capacity or the view of a wheel, a Radwechselanleitung. For particularly important warning messages can also be provided that they are displayed location-independent, in particular this is true for warning messages of the Abstandsregeltempomats or in the event that the device for autonomous driving passes the control to the driver.
