Description

[0001] The present invention relates to a method for displaying information on a vehicle display device with a display capable of generating various viewing-page-specific information displays. In this method, by actuating a control element, which is a displayed button, the information display for a first viewing page is changed so that the information display for a second viewing page is shown for that first viewing page. The invention further relates to a control device for a vehicle with a display device that includes a display capable of generating various viewing-page-specific information displays. The control device also includes a control unit for controlling the information displays of the display for the different viewing pages.Finally, the operating device includes an input unit with a control element that is a displayed button. Pressing this button changes the information display for a first viewing side so that the information display for a second viewing side is shown for that side. The display is specifically designed to simultaneously generate different information displays for different viewing angles. Seats on different sides of the vehicle are assigned to these viewing angles or viewing sides.

[0002] German patent application DE 10 2007 048 599 A1 discloses such a method for operating a vehicle display device and such an operating device. The device described in this document uses a display in which an optical barrier presents a different image to the viewer to the right and left of a central viewing axis. Such displays are also known as dual-view displays. It is known to use such dual-view displays in a motor vehicle to show different information to the driver than to the passenger.

[0003] Furthermore, an active-matrix liquid crystal display is known from EP 1 062 652 B1, which can display different images for different viewing angles. With this active-matrix liquid crystal display, it is particularly possible to show a different image to the driver of a vehicle than to the passenger.

[0004] German patent DE 10 2007 034 272 A1 describes a display and control system for a motor vehicle with a multi-view display device. The system comprises a control device for capturing user input and a detection unit that detects the approach of an actuating element to the control device. The actuating element is assigned to a viewing angle range, so that an actuating action of the actuating element detected by the control device can be assigned to a viewing angle range.

[0005] The subsequently published DE 10 2008 024 416 A1 describes an operating and display system for a motor vehicle with a centrally arranged optical display unit which simultaneously displays two different image outputs for different viewing angle ranges.

[0006] A problematic aspect of using viewing-side-specific or viewing-angle-dependent information displays in a vehicle is the operation of devices supported by the display, or the operation of the information display itself. In particular, when operated by the driver, the challenge lies in ensuring that the operation process is as simple, quick, and intuitive as possible, so that the driver is not distracted from driving.

[0007] It is therefore the object of the present invention to provide a method and an operating device of the type mentioned at the outset, which enable simple and intuitive operation of the information displays reproduced by the display of the display device.

[0008] This problem is solved according to the invention by a method having the features of claim 1 and an operating device having the features of claim 9. Advantageous embodiments and further developments are described in the dependent claims.

[0009] The method according to the invention is characterized in that, in conjunction with the activation of the control element, a graphic object is displayed, at least for the first viewing side, which at least partially reproduces information from both the information display for the first viewing side and information from the information display for the second viewing side. When the button is activated, the position of the button's display changes along with a change in the representation of the graphic object. Thus, when the control element is activated, the user can already see parts of the information display for the other viewing side. This results in the activation of the control element being supported by an intuitively perceptible display.The switch from the information display for a first viewing page to an information display for a second viewing page is visualized by the graphic object when the control element is activated.

[0010] In the context of the invention, a viewing-side-specific information display is understood to mean that a viewing side which, for example, is assigned to viewing the display from the driver's seat, has a different information display than another viewing side which, for example, is assigned to viewing the display from the passenger's seat.

[0011] According to a further development of the inventive method, different information displays can be generated simultaneously for different viewing angles, in particular for different angular ranges, using the display. The display is thus a so-called dual-view display as described, for example, in DE 10 2007 048 599 A1. In this case, in conjunction with the activation of the control element, the graphic object is displayed, at least for the first viewing angle, which at least partially reproduces information from both the information display for the first viewing angle and information from the information display for the second viewing angle.

[0012] According to a further embodiment of the method according to the invention, the control element is a button displayed at least on the first viewing page. For the purposes of the invention, a button is understood to be a control element of a graphical user interface. A button differs from elements and areas for purely displaying information, so-called display elements or display areas, in that it is selectable. When a button is selected, a function assigned to it is executed. This function can only result in a change to the information display. Furthermore, the buttons can also be used to control devices whose operation is supported by the information display. The buttons can thus replace conventional mechanical switches. The buttons can be created and displayed anywhere on the freely programmable display area of ​​the screen.Furthermore, it may be possible to select a button. In this case, the assigned function is not yet executed. However, the selected button is displayed more prominently than other buttons. Selecting and / or highlighting a button can be done using a cursor or by directly interacting with a touch-sensitive surface on the display.

[0013] In the method according to the invention, the position of the button's display changes when the button is pressed. The button is displayed, in particular, in conjunction with the graphical object. Furthermore, the button's position changes, especially in conjunction with a change in the graphical object's display. In this case, the button serves the user as a reference point for switching between the information displays for the different viewing sides or angles. It is a visible element that the user can target and operate. It thus corresponds to a physical tab, handle, or the like. The display generated in conjunction with the activation of the control element therefore visualizes the activation of a physical control element with which one can switch from one information display to another.The operation of the control element is thus graphically visualized in such a way as to support the development of a mental model by the user.

[0014] According to a further development of the inventive method, the display has a touch-sensitive surface, wherein when the button is pressed, the touch-sensitive surface at the button is touched and subsequently a movement is performed on the touch-sensitive surface.

[0015] According to a further embodiment of the inventive method, a control signal is automatically generated depending on an event that influences the display content. This control signal changes the information display for the first viewing page so that the information display of the second viewing page is shown on that page. This type of switching of information displays is particularly advantageous when the event requires a specific information display for a specific viewing page. For example, if a telephone call comes in, the information display for the driver should change so that the incoming telephone call is visualized. Similarly, warning messages from driver assistance systems or the vehicle's navigation system should always be displayed to the driver.In this case, it is advantageous if the information display changes automatically without requiring any operation of the control element.

[0016] According to one embodiment of the inventive method, the graphic object shows a cuboid in which the original information display for the first viewing side is shown on one cuboid face and the information display for the second viewing side is shown on another cuboid face. During activation of the control element, the display of the cuboid is changed, for example, such that the cuboid is pivoted from the display of one cuboid face to the display of the other cuboid face. During the transition from the display of one cuboid face to the display of the other cuboid face, both cuboid faces are shown in a perspective view. Specifically, during activation of the control element, the display of the cuboid is changed such that the cuboid is pivoted from the display of one cuboid face to the display of the other cuboid face.In this way, the activation of the control element is visualized on the display in such a way that the information display for the original viewing side or angle is swiveled away and the information display for the other viewing side or angle is swiveled into the visible area.

[0017] According to a preferred embodiment of the inventive method, the button is displayed on at least one of the cuboid faces. When the cuboid's display is changed, the button pivots with the cuboid face. The display thus gives the user the impression of grasping the cuboid and pivoting it so that the information is displayed from a different viewing angle. Such an operating procedure is very intuitive for the user. In particular, the user can remember the operating procedure very easily.

[0018] According to another embodiment of the inventive method, the graphic object shows a cylinder in which the original information display for the first viewing side is shown on one circumferential section and the information display for the second viewing side is shown on another circumferential section. During actuation of the control element, the display of the cylinder is changed, in particular such that the cylinder is rotated about a vertical axis from the display of one circumferential section to the display of the other circumferential section. Instead of a cylinder, a ring, a cylinder, or the like can also be displayed as the graphic object.

[0019] According to a further embodiment of the inventive method, the information display for the first viewing side already includes a visualization of the information display for the other, second viewing side. The information displays are shown, in particular, on a graphic object. The graphic object is depicted perspectively such that it is pivoted towards the viewing side or viewing angle to which the information display inherently belongs. The information display for the first viewing side is thus shown on the graphic object as pivoted perspectively towards this viewing side. The information display for the second viewing side, when shown as part of the information display for the first viewing side, is shown pivoted away from the first viewing side.

[0020] If the graphic object is a cuboid, a cuboid surface is already visible from a sharp angle when viewing the information for the first side, visualizing the information for the second side. When the control element is activated, the cuboid surface, initially visible from a sharp angle, is rotated to the view for the first side. However, the information for the second side, viewed from the first side, remains slightly rotated, ensuring that the relationship between the information and the respective viewing side is always clear to the viewer.

[0021] According to a further embodiment of the inventive method, a graphic object is displayed as two windows, wherein one window at least partially or at least symbolically displays the information for the first viewing page and the other window at least partially or at least symbolically displays the information for the other viewing page.

[0022] The operating device according to the invention is characterized in that, by means of the control unit in conjunction with the actuation of the operating element, the display can be controlled such that, at least for the first viewing page, a graphic object is displayed which at least partially reproduces information from the information display for the first viewing page as well as information from the information display for the second viewing page. When the button is actuated, the position of the button's display changes along with a change in the representation of the graphic object.

[0023] The operating device according to the invention makes it possible to carry out the steps of the method described above partially or completely.

[0024] According to one embodiment of the operating device according to the invention, different information displays can be generated simultaneously for different viewing angles. In this case, the control unit, in conjunction with the actuation of the operating element, can control the display in such a way that, at least for the first viewing angle, the graphic object can be displayed in such a way that it reproduces at least part of the information displayed for the first viewing angle as well as information displayed for the second viewing angle.

[0025] Preferably, the control unit can display a button as an operating element on the display, at least from the first viewing angle or side. According to another embodiment, the operating element is a mechanical one.

[0026] The display features a touch-sensitive surface. This allows gestures performed on the display surface to be detected and analyzed.

[0027] According to another embodiment, the operating device includes a mechanism that allows user gestures performed in front of the display to be detected and interpreted. In this case, actuating a control element corresponds to performing a gesture in front of the display.

[0028] The invention will now be explained using an exemplary embodiment with reference to the drawings. Fig. Figure 1 shows the arrangement of the display device of an embodiment of the operating device according to the invention in a vehicle, Fig. 2 shows an embodiment of the operating device according to the invention, the Fig. 3A-3E illustrate operating procedures according to exemplary embodiments of the method according to the invention and the Fig. Figures 4A-4E show information displays that are reproduced in connection with exemplary embodiments of the method according to the invention.

[0029] The control device of the exemplary embodiment is located in the area of ​​the center console of a motor vehicle. It comprises a display device with a screen 1, which can show information to the driver and other vehicle occupants. Furthermore, the driver and other vehicle occupants, in particular the front passenger, can control vehicle functions via the control device by making certain inputs.

[0030] Vehicle equipment includes the display device itself, as well as, for example, a navigation system, communication devices such as a mobile phone, multimedia applications such as music playback, a passenger infotainment system, an infotainment system for rear passengers, a television or photo viewer, and the vehicle's own system components. These system components can include, for example, heating and ventilation systems and air conditioning, mirror and seat adjustments, and other features that can be controlled from inside the vehicle.

[0031] Display 1 can generate information displays specific to each viewing side. A viewing side is defined as a side of the vehicle from which Display 1 can be viewed. For example, one viewing side is assigned to the driver 2, who sits in the driver's seat 4, and another viewing side is assigned to a passenger 3, who sits in the passenger seat 5. In the embodiment described below, Display 1 is designed such that different information displays can be generated simultaneously for different viewing angles X and Y, or angular ranges. In this case, the viewing side assigned to the driver 2 is thus assigned to viewing angle X, and the viewing side assigned to the passenger 3 is assigned to viewing angle Y.

[0032] To display different content simultaneously to viewers to the right and left of the central line of sight to Display 1, Display 1 includes an optical barrier. This optical barrier is positioned so that the driver 2, viewed from angle X, can see a first information display, and the passenger 3, viewed from angle Y, can see a second. The individual information displays can be controlled separately, allowing for side- or angle-specific information displays. Certain information displays A are assigned to the driver's side, and other information displays B are assigned to the passenger's side. As will be explained later, it is also possible to display the other information display.

[0033] As in Fig. As shown in Figure 2, the display 1 is coupled to a control unit 8, which in turn is connected to a vehicle course 9. The control unit 8 receives data via the vehicle course 9, which is then displayed on the display 1. The control unit 8 can control the display 1 in such a way that different display content is generated and shown simultaneously for the driver 2 and the passenger 3.

[0034] Furthermore, the operating device includes an input unit, which in this case is designed as a touch-sensitive surface 12 of the display 1. The user can make inputs by, for example, touching the touch-sensitive surface 12 of the display 1 at a specific position with their fingertip 6. A button 10 is displayed on the display 1 as the input element. If the user touches the touch-sensitive surface of the display 1 in the area where the button is displayed, this touch is interpreted by the control unit 8 as an actuation of the button 10. The control unit 8 then implements or initiates the function assigned to the button 10.

[0035] To determine which user pressed the button, a device can also be provided by means of which it is possible to detect which user touched the touch-sensitive surface 12 of the display 1. In particular, it is possible to distinguish whether the driver 2 or the passenger 3 pressed a button 10. Such identification of the seating position is described below with reference to Fig. 2 explained: An electrode array 7 is located in the seat 5 of the passenger 3. An identification code can be capacitively coupled into the passenger 3's body via this electrode array 7. The identification code can identify the seating position of the user 3 as well as the user 3 themselves. The identification code is transmitted via the passenger 3's body and capacitively coupled out at the fingertip 6 so that it can be transmitted to a receiver located in the display device, in particular the display 1.

[0036] The receiving device is connected to the control unit 8, which in turn is capacitively coupled to the electrode unit 7. The capacitive couplings between the electrode unit 7 and the passenger 3 on the one hand, and between the passenger 3 and the receiving device in the display unit on the other, utilize an electric field with a very limited range, e.g., a few centimeters or decimeters. Relatively low carrier frequencies of a few hundred kHz are used for signal transmission, resulting in quasi-static fields, i.e., fields for which the physical principles applicable to static fields largely apply. For further details of this signal transmission, reference is made to DE 10 2004 048 956 A1 and the further literature cited therein, which are hereby incorporated into the present application by reference.In particular, the circuit devices used in DE 10 2004 048 956 A1 can be applied. A corresponding electrode device 7 is also located in seat 4 of the driver 2.

[0037] The following refers to the Fig. Section 3A-3E explains how to switch between the different information displays A and B for driver 2 and passenger 3, respectively. It is assumed that information display A is assigned to driver 2 and information display B is assigned to passenger 3. As explained below, driver 2 and passenger 3 can also display the information display assigned to the other viewer. The following explanations focus only on the information display for the driver's side, as shown for viewing angle X. Furthermore, they only address the operation of controls, i.e., in this embodiment, the operation of buttons 10, by driver 2. The information display for passenger 3 at viewing angle Y can be changed accordingly by passenger 3.If buttons 10 for activation by the driver 2 and for activation by the passenger 3 are displayed in identical positions, the above can be applied with reference to . Fig. 2 explains that it can be automatically distinguished whether the operation was carried out by the driver 2 or the passenger 3.

[0038] In Fig. 3A shows the output information display A for the driver 2 on the left. A button 10 is displayed within the information display A. When the driver touches the touch-sensitive surface 12 of the display 1 at button 10 with their fingertip 6, the middle one appears in Fig. Display 3A is shown. In this case, the original information display A no longer fills the entire display area. Instead, a cuboid is displayed as graphic element 11 in perspective, containing the original information display A on the larger visible surface of the cuboid. Simultaneously, however, information display B, which is assigned to passenger 3, is at least partially visible on a smaller surface of the cuboid. The current information display B of passenger 3 can be shown on the smaller surface of the cuboid. Furthermore, button 10 remains visible within information display A, which is now shown on a surface of the cuboid of graphic object 11.

[0039] If the driver 2 now moves their fingertip 6 further to the left on button 10 on the touch-sensitive surface 12 of the display 1, they move button 10 according to the movement of fingertip 6, while simultaneously the cuboid is rotated so that the cuboid surface with information display A becomes smaller and the cuboid surface with information display B becomes larger. On the right side of the Fig. Figure 3A shows the final view when driver 2 has moved button 10 to the upper left corner of display 1 with their fingertip 6. Driver 2 now sees information display B, which is actually assigned to passenger 3.

[0040] Such an operating procedure is very intuitive for the user who wants to switch from information display A to information display B, since button 10 acts like a physical handle attached to the cuboid, which the user can use to swivel the cuboid. The cuboid, used as graphic object 10, symbolizes a physical object that displays information display A on one surface and information display B on another. It is essential that when button 10 is pressed, graphic object 11 not only displays information display A for one viewing angle A, but also at least partially displays information from information display B for the other viewing angle B. In this way, the user can recognize which information display they are switching to when they press the control element, i.e., in this case, button 10.

[0041] The passenger 3 can also activate a corresponding button 10, which may be displayed in a different position, to access the information display visible from viewing angle Y. In this way, both the driver 2 and the passenger 3 can view either information display A or information display B. Furthermore, it is possible for the driver 2 to view information display A and the passenger 3 information display B, or vice versa.

[0042] In Fig. Figure 3B shows three views of Display 1, through which the user can switch from Information Display A to Information Display B in a different way. In this case, no button 10 is shown as a control element. Instead, a gesture performed by the user with their fingertip 6 is interpreted as actuating the control element. The user can perform the gesture either on the touch-sensitive surface 12 of Display 1 or within a control zone in front of Display 1, provided the input unit includes appropriate means for detecting such a gesture in front of Display 1. If the gesture is performed on the touch-sensitive surface 12 of Display 1, the user can touch Display 1 at any position and then, for example, drag their fingertip 6 to the left on the touch-sensitive surface 12 of Display 1.In conjunction with performing this gesture, as shown in the middle view of the . Fig. Figure 3B shows a cuboid as graphic object 11, which displays information A on one cuboid surface and information B on another cuboid surface, and which is rotated, as already shown with reference to the Fig. 3A was explained. Furthermore, it may be provided that the gesture is performed by simultaneously touching the touch-sensitive surface 12 of the display 1 with two fingertips, provided that the input unit is designed in such a way that the simultaneous touching of the surface in two delimited areas can be detected and interpreted as an input gesture.

[0043] In Fig. Figure 3C shows two views of Display 1, in which a button 10 is displayed below information display A or B. If the user touches this button, for example with their fingertip 6, the display switches to the other information display. The way in which the information display on Display 1 changes when button 10 is pressed will be explained later with reference to the Fig. 4 explained.

[0044] In Fig. Three 3D views of Display 1 are shown, illustrating another way to switch between information displays A and B. As with the initial view, which is also shown in Fig. As shown in Figure 3C, a button 10 is displayed below information display A. When the user touches this button 10 with their fingertip 6, a selection menu appears. This selection menu includes a graphic object 11, which contains both information display A and information display B in two windows. If necessary, information displays A and B can be shown in a reduced size or only symbolically. The user can then select the desired information display by, for example, touching the corresponding area on the touch-sensitive surface 12 of the display 1. For example, if they select information display B in the middle view of the Fig. When 3D is turned off, the display on screen 1 switches to the right side. Fig. 3D rendering.

[0045] In Fig. Figure 3E shows a further embodiment of the operating device according to the invention, in which, instead of buttons 10 being displayed on the display 1, two mechanical toggle switches 13 are provided as operating elements. One toggle switch 13 is provided for the driver 2, the other toggle switch 13 is provided for the passenger 3. By means of the toggle switch 13, the driver 2 or the passenger 3 can switch between the different information displays A and B. The display associated with the actuation of the mechanical toggle switch 13 will be described later with reference to the Fig. 4 explained.

[0046] In addition to the various actions of the button 10 or the mechanical switches 13, the information display can also change automatically, i.e., without the user operating any control element, when the control unit 8 receives a signal for a specific event that changes the display content on the screen 1. For example, if the passenger 3 is shown information display B, which is associated with the navigation system, and the control unit 8 receives a warning message via the vehicle's path 9, which is displayed within the navigation system's screen, the information display for the driver 2's viewing angle A can automatically switch to information display B for the passenger 3, so that the warning message is displayed to the driver.

[0047] With reference to the Fig. Sections 4A-4E now describe the displays on Display 1 that appear in conjunction with the activation of the control element. Activation of the control element can be understood as an operation that extends over a specific time interval. The change in the display on Display 1 can begin at the start of the operation and end at the end of the operation. For example, a change in the display can be triggered as soon as the touch-sensitive surface 12 of Display 1 is touched at a specific button 10. Alternatively, the change in the display can be triggered only after the user has made a slight movement on the touch-sensitive surface of Display 1, starting with the movement at a button 10.

[0048] All displays generated on Display 1 in conjunction with the activation of a control element have in common that a graphic object 11 is displayed, which at least partially reproduces information from the information display for different viewing angles or viewing sides. The various in the Fig. The displays shown in 4A-4E can be combined with any actuation of a control element, as related to the Fig. 3A-3E have been explained. However, if buttons 10 are displayed on a touch-sensitive surface 12 of the display 1, which are moved in their position by a gesture of the user, the display that supports the operation preferably corresponds to the display that visualizes the change of the information displays.

[0049] Fig. Figure 4A shows three views of display 1, in which a cuboid is rotated as graphic object 11, as already mentioned in relation to the Fig. 3A and Fig. 3B was explained.

[0050] Fig. 4B shows a similar rendering to the one related to Fig. 4A was explained. In the initial state, which is on the left in the Fig. As shown in Figure 4B, the user does not see information display A in full screen. Instead, the cuboid is already visible, but only slightly rotated, so that the cuboid surface with information display B is perspectivally visible from a very acute angle. Thus, in the normal view, the user can already perceive information display B for the other side of the screen, at least partially or symbolically. The information display A assigned to driver 2 is displayed in such a way that it is also shown on the cuboid surface, perspectively rotated towards driver 2. For example, if driver 2 switches modes by activating a control element, as described above with reference to the... Fig. 3A-3E, explained with regard to information display B, the cuboid is rotated until the cuboid surface representing information display A is only recognizable from a sharp perspective angle, and the cuboid surface with information display B occupies most of the display 1. However, in the perspective rendering of the cuboid, the cuboid surface with information display B, which is assigned to passenger 3, is shown as having been rotated towards passenger 3.

[0051] If, in this configuration, the user wishes to activate further buttons belonging to functions displayed on information display A or B, it may be provided that, as the operating hand approaches, the display changes so that the corresponding information display A or B completely fills display 1, as described in relation to Fig. 4A explains. The approach of the operating hand can be detected, for example, by an infrared sensor located below display 1. This change in the display for the activation of buttons on display 1 has the advantage that the buttons are displayed undistorted and as large as possible for operation.

[0052] In Fig. Figure 4C shows three views of the display 1, which are displayed in conjunction with the operation of a control element. When switching from information display A to information display B, two windows are displayed as graphic object 11, which show reduced sizes of information displays A and B. This transition from information display A to information display B can be shown, in particular, in conjunction with the operation of buttons 10 or toggle switches 13, as shown with reference to the Fig. 3C, Fig. 3D and Fig. 3E was explained.

[0053] In Fig. 4D shows a transition from information display A to information display B, which corresponds to the one in Fig. The transition shown in Figure 4C is similar. In this case, however, the two windows of the graphic object 11 are not displayed completely, but only partially, whereby when the control element is activated, the window with information display A is reduced in size and the window with information display B is enlarged. Through the operating process, which in this case is in particular a gesture in which the user moves their fingertip 6 from right to left on the touch-sensitive surface 12 of the display 1, the window with information display B is preferably moved into the display of the display 1 synchronously with the movement of the fingertip 6.

[0054] Finally, in the Fig. Figure 4E shows three displays of Display 1, in which a cylinder or ring is represented as the graphic object 11 instead of the cuboid. The cylinder displays information A on one half of its circumference and information B on the other half. At the start of the operation, the display switches from the full-screen view of information A to a representation of the cylinder, in which both information A and at least part of information B are displayed on the cylinder's circumference. If the user now moves, for example, their fingertip 6 from right to left on the touch-sensitive surface 12 of Display 1, the cylinder is rotated accordingly around a vertical axis until only the section of the circumference with information B is displayed. From this view, the display then jumps to the full-screen view of information B, as shown in the right-hand view of the Fig. 4E is shown.
