[0096] Furthermore, the operating device 14 comprises a switch circuit board 34 and, by way of example, three further circuit boards 36. The microswitch 24 is arranged on the switch circuit board 34.

[0097] The housing 26, the display carrier 28, the display 16 and the front glass 30 have the same, for example rectangular, shape when viewed from the outside with regard to the front glass 30.

[0098] The display 16 is positioned on the display carrier 28 such that the windscreen 30 is freely accessible and visible from the surroundings. An image 18 displayed by the display 16, for example a user interface, is visualized behind the windscreen 30. The image 18 is visible through the windscreen 30. The windscreen 30 faces the interior of the vehicle 10.

[0099] The display carrier 28 with the display 16 and the front glass 30 are held in the housing 26 by means of the guide mechanism 32.

[0100] The guide mechanism 32 comprises a butterfly element 38 and, by way of example, four bearing elements 40.

[0101] Butterfly element 38 is an approximately rectangular frame. One in the Fig. 2. The upper, approximately U-shaped frame part is connected via two flexible connections to a section in the Fig. The two lower, approximately U-shaped frame sections are connected. The two U-shaped frame sections can be pivoted relative to each other via the flexible connections.

[0102] In the area of ​​the four corners, the butterfly element 38 has four bearing axes 42. The bearing axes 42 run parallel to each other and parallel to the respective pivot axes of the two flexible connections between the U-shaped frame parts of the butterfly element 38. Each of the bearing axes 42 is movably connected to one of the four bearing elements 40. The four bearing elements 40 are attached in respective receptacles 44 on the base of the housing 26.

[0103] Furthermore, the guide mechanism 32 has two spring elements 46. The spring elements 46 are attached in corresponding receptacles 48 on the base of the housing 26. The receptacles 48 for the spring elements 46 are located in an area that is defined by the receptacles 44 for the bearing elements 40. The receptacles 48 for the spring elements 46 are located on opposite sides of a switch receptacle 50. The circuit board 34 with the microswitch 24 is mounted in the switch receptacle 50.

[0104] The spring elements 46 are located between the rear of the display carrier 28 and the base of the housing 26. The spring elements 46 are supported against both the base of the housing 26 and the rear of the display carrier 28. When the actuating device 20 is activated, the spring elements 46 are elastically tensioned by the mechanical force exerted on the display carrier 28, which moves it towards the housing 26. When the force is released, the spring elements 46 cause the display carrier 28 to return to its initial position. The microswitch 24 is implemented as a momentary switch.

[0105] If an external mechanical force acts on the front glass 30, the display carrier 28 with the display 16 is forced into place, as shown, for example, in a sectional view in the Fig. As shown in Figure 6, the display carrier 26 with the display 16 is moved relative to the housing 26. The guide mechanism 32 guides the display carrier 26 with the display 16 in such a way that it is not tilted. The display carrier 26 with the display 16 is thus moved parallel to itself.

[0106] The display carrier 28 has a display mounting section 52 and a connecting section 54. The display mounting section 52 and the connecting section 54 are formed as a single unit. The display mounting section 52 is approximately rectangular in shape. The display 16 is arranged on one surface of the display mounting section 52. The connecting section 54 is located on the rear surface of the display mounting section 52, opposite the display 16. The connecting section 54 is approximately rectangular in shape.

[0107] The butterfly element 38 has four connecting flanges 58. The connecting section 54 of the display carrier 28 is attached to the butterfly element 38 via the connecting flanges 58.

[0108] Furthermore, the display carrier 28 has a stamp section 56. The stamp section 56 is in the Fig. 5 and Fig. Figure 6 shows that the stamp section 56 is integrally formed with the display mounting section 52. The stamp section 56 is located on the same side of the display mounting section 52 as the connecting section 54. The stamp section 56 is arranged within an area surrounded by the connecting section 56. The stamp section 56 extends approximately perpendicularly from the rear surface of the display mounting section 52 facing away from the display 16. An imaginary axis of the stamp section 56 is coaxial with an imaginary axis of the button of the microswitch 24.

[0109] As long as no mechanical force is exerted on the windscreen 30, the piston section 56 remains at rest, as shown in the Fig. Figure 5 shows the microswitch 24 being pressed with almost no force. In this position, the microswitch 24 is not actuated.

[0110] Furthermore, the operating device 14 includes a front lighting device 60 and an ambient light sensor 62. The front lighting device 60 and the ambient light sensor 62 are located in a side section on the side of the display 16 facing the front window 30.

[0111] The front lighting device 60 comprises several light sources, for example, LEDs. The front lighting device 16 can illuminate the front of the display 16 facing the front glass 30.

[0112] The ambient light sensor 62 can be used to determine the intensity of the ambient light.

[0113] The ambient light sensor 62 and the front lighting device 60 are each connected to an operating control unit 64 of the operating device 14. The operating control unit 64 is, for example, located in the Fig. 7 shown. Fig. Figure 7 shows a functional diagram of the operating device 14. The operating control unit 64 is implemented with electronic components, for example processors. The components of the operating control unit 64 are arranged on the circuit boards 36.

[0114] The front lighting device 60 can be activated depending on the intensity of the ambient light, which is determined by the ambient light sensor 62. The display 16 can thus be illuminated as needed, for example in low ambient light.

[0115] Furthermore, three connection interfaces 66 extend laterally from the display 16. These connection interfaces 66 are implemented as flexible cables, for example, ribbon cables or flexible circuit boards. The display 16 is connected to the vehicle control unit 12 via cables connected to these interfaces 66.

[0116] Furthermore, the operating device 14 includes a driver unit 68. The driver unit 68 comprises electronic components. The driver unit 68 is arranged on the circuit board 36. The driver unit 68 controls the display of images 18 on the display 16. The driver unit 68 is connected to the display 16 and the operating control unit 64. The driver unit 68 can also be implemented as part of the display 16.

[0117] The operating control unit 64 comprises a microswitch control unit 70 and a main processor 72. The microswitch control unit 70 includes a control algorithm 81, for example, software. The control algorithm 81 can detect the switching state of the microswitch 24.

[0118] The main processor 62 includes a control algorithm 81, for example, software. The main processor 62, via the driver unit 68, can control the pixels of the display 16 to display images 18. Furthermore, the main processor 62 can receive and process touch information from the touch sensor 22. Additionally, the main processor 62, via the microswitch control unit 70, can receive and process signals from the microswitch 24.

[0119] The operating control unit 64 is connected to the driver unit 68 via a suitable data transmission system, for example, a Universal Serial Bus (USB). The driver unit 68 is connected to the display 16 via a suitable electrical connection, for example, a flexible circuit board. The microswitch 24 is connected, for example, to the microswitch control unit 70 of the operating control unit 64 via a separate data transmission system, for example, a cable.

[0120] In Fig. Figure 8 shows six images 18, each showing a user interface displayed with the display 16 of the operating device 14.

[0121] In Fig. Figure 8, top center, shows image 18 for a start user interface. Fig. 8, top left, is image 18 for a music selection user interface and below it, in Fig. Figure 8, bottom left, shows image 18 for a music output user interface. Fig. 8, top right, is image 18 for a vehicle user interface and below it in Fig. Figure 18, bottom right, shows a tire pressure user interface. Fig. Figure 18, shown in the bottom center of Figure 8, depicts an air conditioning user interface.

[0122] Each of the user interfaces has several buttons 74 and several display fields 76. For the sake of clarity, only the start user interface is shown in Figure 18. Fig. 8, top center, some of the buttons 74 and some of the display fields 76 are marked with reference marks. For the sake of clarity, all other elements that also appear in the start user interface are only marked with reference marks there.

[0123] The buttons 74 are virtual controls on the respective user interface. Touching the user interface in the area of ​​a button 74 selects one of the functions assigned to that button 74. Confirmation of the function selection is achieved by pressing, for example, a finger 80 on the front panel 30 in the area of ​​the button 74, which triggers the microswitch 24. Fig. 6 is indicated by finger 80 as an arrow.

[0124] The display fields 76 are used to display information, such as numbers, letters, words, symbols or the like.

[0125] Alone Fig. The eight user interfaces shown have a button 74 "House icon" and a button 74 "Triangle icon" in the upper right corner. Pressing button 74 "House icon" displays image 18 for the start user interface. Pressing button 74 "Triangle icon" activates or deactivates the vehicle's hazard warning lights (not shown).

[0126] On the Start interface, the Climate Control interface, and the Music Output interface, buttons 74 (House icon) and 74 (Triangle icon) are highlighted in red. On the Music Selection interface, the Vehicle interface, and the Tire Pressure interface, buttons 74 (House icon) and 74 (Triangle icon) are highlighted in white.

[0127] The first time the control device 14 is switched on, the image 18 of the start user interface is displayed.

[0128] The start user interface, the climate control user interface, and the music output user interface each have two temperature fields 78, which are assigned to the left and right seating areas of the vehicle 10. The temperature fields 78 have a black background. Each temperature field 78 has a display field 76 for showing the currently set temperature. For example, in the Fig. The display shows "22", which corresponds to a temperature of 22 °C. Next to the temperature display field 76 are two buttons 74 for adjusting the temperature. Pressing button 74 "+" increases the selected temperature. Pressing button 74 "-" decreases the selected temperature.

[0129] The start user interface and the music output user interface feature three buttons below the temperature fields 78: "Music", "Climate", and "Car", which have a black background. Pressing button 74 "Music" switches to the music selection user interface. Pressing button 74 "Climate" switches to the climate control user interface. Pressing button 74 "Car" switches to the vehicle user interface.

[0130] The climate control user interface has a total of five buttons 74 below the temperature fields 78 for switching the seat heaters of the two front seats, the air conditioning, the rear window heater, and the windshield heater on and off. These buttons 74 have a black background. In the Fig. The five buttons (74) are marked with the usual pictograms.

[0131] The music selection user interface does not have a temperature field 78. Instead, there are, for example, three buttons 74 for selecting music tracks, labeled "Song 1", "Song 2", and "Song 3". These buttons 74 also have a black background. Furthermore, the music selection user interface has a display field 76 "Music" in the lower left corner, indicating that the music selection user interface is displayed.

[0132] The music output user interface features a display field 76 at the bottom for the currently selected music track, which in this example is song three. Display field 76 has a black background.

[0133] The vehicle user interface and the tire pressure user interface do not have a temperature field 78. Instead, a passenger car icon with a white background is displayed. A display field 76 labeled "Car" is located in the lower left corner, indicating which vehicle-related user interface—namely the vehicle user interface or the tire pressure user interface—is currently active.

[0134] The vehicle user interface features two white buttons (74) to the left of the vehicle icon for selecting two aerodynamic settings, labeled "Aero light" and "Aero +" for example. To the right of the vehicle icon are two white buttons (74) for selecting two chassis settings, labeled "Eco" and "Sport" for example. Below the vehicle icon is a white button (74) labeled "Tires," which opens the tire pressure user interface.

[0135] The tire pressure user interface features two white display fields 76 below the vehicle icon, each corresponding to one of the tires on the icon. These display fields show the respective tire pressure, for example, "2.1" and "2.2". Below these two display fields 76 is another white display field 76 labeled "Tire pressure", which indicates that the tire pressure user interface is currently displayed. In the upper left corner of the tire pressure user interface is a white arrow-shaped button 74, which allows the user to return to the vehicle user interface.

[0136] The following describes the process for activating buttons 74 using the Fig. 5 and Fig. 6 explained in more detail.

[0137] Examples include the Fig. 5 and Fig. 6 designates a location where button 74, which is to be pressed, is located. Fig. Figure 5 shows a sectional view of the operating device 14 in a basic state before the button 74 is pressed. Fig. Figure 6 shows the corresponding sectional view of the operating device 14 during the actuation of button 74.

[0138] To activate the buttons 74, the user touches the area of ​​the front panel 30 where the button 74 is located with a finger 80 of their hand. The touch sensor 22 determines the position of the finger 80 relative to the user interface. The determined position of the finger 80 is transmitted via the driver unit 68 to the operating control unit 64. If the position of the finger 80 corresponds to the position of the button 74, the button 74 is recognized as selected. The touch sensor 22 acts as a position detection means for selecting the buttons 74.

[0139] As soon as the user presses their finger 80 against the contact point on the front panel 30, the display carrier 28 with the display 16 is moved towards the housing 26. This elastically tensions the spring elements 46. The microswitch 24 is actuated by the plunger section 56 of the display carrier 28. When the microswitch 24 is actuated, the user receives haptic feedback via their finger 80. The microswitch 24 acts as a feedback device. The actuation of the microswitch 24 is detected by the microswitch control unit 70 and forwarded to the main processor 72. The selected button 74 is then recognized as activated. The microswitch 24 acts as a confirmation device for the selection of button 74.

[0140] When the finger 80 is removed from the front glass 30, the elastic tension of the filter elements 46 causes the display carrier 28 with the display 16 to move into its position in the Fig. The starting position shown in section 5 is returned.

[0141] Instead of passive haptic feedback when the microswitch 24 is actuated, a device for active haptic feedback, for example a piezo element, a magnetic coil or the like, can also be provided, which can be integrated, for example, in the display 16.

[0142] In an alternative embodiment of the operating device 14, not shown, another switching device, for example a sensor or a touch switch, can be provided instead of the microswitch 24 to confirm the selection of the buttons 74.

[0143] The following is an exemplary procedure for generating images 18 on the display 16 using a flowchart. Fig. 9 explained in more detail. The procedure is carried out using a software-implemented control algorithm 81. The software can be described as a display control device, which controls the display 16 to output images 18.

[0144] In a start step 82, software for controlling the display 16 is initialized. Furthermore, the display 16 is controlled via the driver unit 68 so that the image 18 for the start user interface is displayed, as shown in the Fig. 10 is shown in the upper left corner.

[0145] In a sensor test step 84, it is checked whether the touch sensor 22 reports a touch of the front glass 30 in the area of ​​one of the buttons 74 of the user interface currently shown in Figure 18.

[0146] If no touch of buttons 74 is detected, the sensor test step 84 is repeated until a touch of one of buttons 74 is detected.

[0147] If a touch of one of the buttons 74 is detected in the sensor test step 84, a confirmation query step 86 checks whether the selection of button 74 was confirmed by actuating the microswitch 24.

[0148] If the check in the confirmation query step 86 shows that there is no confirmation of the selection of a button 74, the procedure steps from sensor check step 84 are repeated.

[0149] If the check in confirmation query step 86 shows that the selection of button 74 has been confirmed, then a mode check step 88 verifies whether pressing button 74 triggers a change of the user interface to a different user interface. In the Fig. Figure 10, for example, shows a switch from the start user interface, top left, to the vehicle user interface, bottom right.

[0150] If the check in mode test step 88 shows that no change to the user interface is necessary, the already displayed user interface is updated in an image refresh step 90. The contents of the display fields 76 are updated without fundamentally changing the user interface. To update the displayed user interface, the image data is read from the operating control unit 64 by the driver unit 68, and the updated image 18 is generated. This process can also be referred to as "rendering".

[0151] For example, in the Fig. In the start user interface shown in the upper left, pressing one of the buttons 74 “+” to increase the temperature results in a change in the temperature, but no switch to a different user interface occurs. The corresponding display field 76 for the temperature is updated accordingly to the newly selected temperature.

[0152] If the check in mode check step 88 indicates that a change of user interface is required, image 18 is refreshed with the currently displayed user interface in an image refresh step 92. To refresh the displayed user interface, the image data is read from the operating control unit 64 by the driver unit 68, refreshed, and the refreshed image 18 is generated. This process can also be referred to as "rendering." For the refresh, the pixels of image 18 that are affected by the change of user interface are controlled to output the color that is complementary to the color that was displayed before the change of user interface.

[0153] In Fig. Figure 10 shows the updated image 18 of the start user interface in the center. The changes affect the pixels in the area of ​​button 74 with the house icon and button 74 with the triangle icon. The pixels originally controlled to output red are now controlled to output green. Green is the complementary color to red. Furthermore, the pixels of the temperature fields 78, which were originally controlled to output black, are now controlled to output white. White is the complementary color to black. The pixels for displaying the originally black display fields 76 for the temperature reading and the black buttons 74 for changing the temperature are also controlled to output white. In addition, the pixels for displaying the originally white buttons 74 "Music," "Climate," and "Car" are also controlled to output white.

[0154] Subsequently, in a delay check step 94, it is checked whether a delay time specified, for example, in the operating control unit 64, has elapsed. If delay check step 94 detects that the delay time has not elapsed, the delay check step 94 is repeated until the elapsed delay time is detected.

[0155] If the delay check step 94 detects that the delay time has expired, the image 18 for the new user interface is displayed in the image refresh step 90. To change the user interface, the image data for the new user interface is read from the operator control unit 64 by the driver unit 68 and the new image 18 is generated. In the Fig. The vehicle user interface is displayed in the bottom right corner after the change. Displaying the new image (18) takes 100 ms or more.

[0156] The process steps are then repeated starting from sensor test step 84.

[0157] By addressing the pixels affected by the user interface change with their complementary color in image refresh step 92 before image 18 for the new user interface is displayed in image refresh step 90, ghosting effects resulting from the originally displayed image 18 are avoided. These ghosting effects can occur particularly during the transition from colored to white displays. White is the default state of the pixels. The inventive method, especially image refresh step 92, ensures that a display in pure white can occur after a colored display. Without the inventive method, the pixels used to output colored displays do not output the default white, but rather gray.

[0158] An alternative method involves omitting the pixels of the original image 18 that represent black or white during image refresh step 92. Extensive testing has shown that ghosting effects occur less frequently or not at all with black and white. This can increase the speed when switching between user interfaces.

[0159] In the Fig. 11, Fig. 12 to Fig. Figure 13 shows a second embodiment of an operating device 214. Those elements which correspond to those of the first embodiment from the Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 to Fig. The 10 similar embodiments are provided with the same reference numerals plus 100. The second embodiment differs from the first embodiment in that the operating device 214 is not permanently installed in the vehicle 10. The operating device 214 can also be used outside the vehicle 10 to display images 218 relating to the vehicle 10 and to adjust functions relating to the vehicle 10.

[0160] In the operating device 214, a switch 224 is arranged on the side of the housing 226 facing away from the display 216. The setting, for example activation or deactivation, of functions relating to the vehicle 10 is carried out in the operating device 214 by actuating the switch 224.

[0161] The functions that can be set using switch 224 include, for example, the locking functions of the doors and windows. Furthermore, the function of a parking heater can be set using switch 224, in particular, it can be activated or deactivated.

[0162] Furthermore, the operating device 214 has an electrical energy source, for example a battery.

[0163] As long as switch 24 is not activated, the image 218, which was displayed when switch 224 was last activated, will be shown on display 216.

[0164] For example, the display shows 216 in the Fig. 11. An image 218 in the form of a black logo on a white background, which characterizes the vehicle 10. Alternatively, the display 216 can also show other images 218, which may also include letters, numbers, symbols, or the like. For example, the image 218 could represent the logo of the manufacturer of the vehicle 10, or a license plate of the vehicle 10, or the like.

[0165] The display 216, designed as an electronic paper display, does not require any conservation energy to maintain the constructed image 18.

[0166] The activation of switch 224 can be indicated by a change in the image 218 on the display 216. For example, as shown in the Fig. As shown in Figure 12, the color of the area surrounding the black logo can be changed from white to green. This setting can remain in effect until switch 224 is activated again.

[0167] To output an image 218 on the display 216, the following is done in the Fig. The methods described in the invention are used as described in 9.

[0168] The operating device of two 14 can, for example, have the function of a remote control, such as a radio-operated vehicle key or the remote control of a parking heater or the like.

[0169] Optionally, the vehicle 10 can be provided with a receptacle for the operating device 214 according to the second embodiment. The operating device 214 can be stably arranged in the receptacle.

[0170] Furthermore, the device can include a portion of an electrical charging device with which the power source of the operating device 214 can be charged. A contact-based charging device can be provided. In this case, the operating device 214 can have corresponding electrical contacts. For example, the operating device 214 can have an electrical plug connection or the like. Alternatively, an induction-based charging device can be provided. In this case, the operating device 214 does not require any electrical contacts.
