DETAILED DESCRIPTION

[0023] It is to be understood that the disclosure is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The Figures and written description are provided to teach those skilled in the art to make and use the inventions for which patent protection is sought. The disclosure is capable of other embodiments and of being practiced and carried out in various ways. Those skilled in the art will appreciate that not all features of a commercial embodiment are shown for the sake of clarity and understanding.

[0024] In addition, it is to be understood that the phraseology and terminology employed herein are for the purpose of describing the present disclosure and should not be regarded as limiting. For example, the use of a singular term, such as, a is not intended as limiting of the number of items. Also, the use of relational terms, such as but not limited to, top, bottom, left, right, upper, lower, down, up, side, are used in the description for clarity in specific reference to the Figures and are not intended to limit the scope of the present disclosure. Further, it should be understood that any one of the features may be used separately or in combination with other features. Other systems, methods, features, and advantages will be or become apparent to those skilled in the art upon examination of the Figures and the description. The term driver is used throughout this disclosure but is not limited to a person who is operating or controlling the vehicle; it may refer to any vehicle occupant, person, passenger, or user inside the vehicle, or, in certain circumstances, a person who is outside the vehicle but controlling the vehicle or interested in movement of the vehicle. It is intended that all such additional systems, methods, features, and advantages be included within this description, and be within the scope of the present disclosure.

[0025] A motor vehicle, which in its entirety is designated by reference numeral 10, includes a driver's seat 12 with a seat surface 14 and a backrest 16. The backrest 16 is adjustable in terms of its inclination in relation to the seat surface 14. The seat 12 can here also be rotated in its entirety, for example, in order to enable the driver to turn to face the passengers seated at the back of the motor vehicle 10 during autonomous operation of the motor vehicle 10. In the upright sitting position shown in FIG. 1, a head 18 of the driver 20 is directed towards a windscreen 22 of the motor vehicle 10, so that the driver can perceive the traffic situation. Further information, such as the speed of the motor vehicle 10, a map display or similar can be displayed on a dashboard 24 or via projection onto a headup display on the windscreen 22. The motor vehicle 10 further includes a front view camera 26, which can record the traffic situation in front of the motor vehicle, and a camera 28 pointing inward , with which contact-free inputs by the driver 20 can be recorded, for example.

[0026] If, during autonomous operation of the motor vehicle 10 or when the motor vehicle 10 is at a standstill, the driver 20 readjusts the backrest 16 of the driver's seat 12 into the leaned back resting position shown in FIG. 2, this is recorded by corresponding sensors in the driver's seat 12. In order to enable the driver 20 to also have a view in this position onto the traffic situation on the front side, a signal from the front image camera 26 is now shown on a headliner 30 of the motor vehicle 10. This can be shown using a video projector; alternatively, the headliner 30 can also be designed as a flexible or form-adapted monitor, partially or over its entire surface.

[0027] This makes it possible that in the resting position also shown in FIG. 2 the driver 20 can also view the traffic situation, so that their attention is not negatively impacted and if applicable, travel sickness due to a discrepancy between their visual perception and their perception of speed and acceleration is avoided.

[0028] In addition to the signal from the front image camera 26, further information can also be shown on the headliner 30, such as the image of a headup display or also signals from additional cameras, such as a rear view camera.

[0029] If the driver 20 does not wish to have this display, it is possible for them to change the display mode and the signal shown on the headliner 30 via contact-free inputs, which can for example be recorded by the camera 28. For example, as an alternative to the signal from the front image camera 26, a signal from an entertainment system, a signal from a telecommunications system, such as email or SMS, or an operating interface for a telephone system or similar can be shown. If the driver does not wish to receive distracting displays or displays showing unnecessary information on the headliner 30, a background image or a background video, such as the image of a starry sky, can be shown. It is further possible for the driver 20 to move the display of an additional display apparatus, such as a monitor in the dashboard 24, onto the headliner 30.

[0030] Examples of possible contact-free inputs are summarized in FIG. 3. For example, as shown in FIG. 3A, gestures of the extremities of the driver 20 can be recorded by the camera 28. A recording of their entire body posture or iris position and/or direction of view is also possible. Here, it is also possible to record whether the eyes of the driver 20 are open or closed, which can also be used as a control signal for the display on the headliner 30.

[0031] FIG. 3B illustrates how through eye movements or hand movements of the driver 20, different display modes can be selected on the projection surface, in this case, the headliner 30. FIGS. 3C and 3D illustrate how the display of an additional display area can be transferred onto the display in the headliner 30 by gesture control . This can be achieved through simple virtual movement of the display by means of a corresponding gesture.

[0032] FIG. 4 shows a control diagram for a control appliance for implementing the method. In one method step S10, signals from the front view camera 26 are here first recorded. At the same time, in one method step S12, headup display information is generated and in a further method step S14, the signals from an interior rear view camera are recorded. In addition, in one method step S16, information about the sitting position is recorded. In step S18, the recorded signals from the front view camera and the rear view camera, and the generated signal for the headup display are summarized, wherein depending on the recorded sitting position, the display area is changed. If the driver 20 moves their seat into the resting position shown in FIG. 2, in step S20, the headliner 30 is selected as the display area. If the driver 20 moves the sitting position back into the upright position shown in FIG. 1, in step S22, the display on the headliner 30 is deactivated again.

[0033] In a further step S24, the recording of additional contact-free inputs by the driver 20, as already described above, is made as summarized in FIG. 3. Depending on the type of contact-free input by the driver 20, in a further step S26, the display is then changed to an entertainment system, in step 28 a background image, such as a starry sky, is shown or in step S30 the display of an additional screen is moved onto the headliner 30. Naturally, in additional method steps, which are not shown in detail, further display modes can be selected, as has already been described above.

[0034] Overall, therefore, the display mode of the motor vehicle 10 can always be adapted with a minimum of active inputs to the current configuration of the motor vehicle 10 and to the needs of the driver 20.

[0035] The features of the invention disclosed in the above description, in the drawings and in the claims can be essential both individually and in any combination required for the realization of the invention in its different embodiments.
