advantageous embodiments and further developments of the invention are specified in the dependent claims.

According to the invention is a manual actuating means an operating system for a vehicle designed as a touchpad and on a screen is in at least one viewport a selected one Field visible marked, with a change of the selected field on the screen by a corresponding one of an attachment point independent, sliding wiping movement with a specifiable contact force on the touchpad in an alternating direction is feasible, with the selected field is changed when the sliding wiping movement at least one Crossing field length exceeds.

With the touchpad can on the screen displayed entries of a menu structure with several menu levels intuitively selected and / or to be activated.

By the separate version the touchpad as an input device can be ergonomically optimized in the gripping area can be arranged and the screen display can be used as output means be arranged in the optimum field of view.

By the visible representation of the selected field on the screen receives the user advantageously always direct feedback on the current position within the menu structure. The currently selected field is also highlighted when no finger on the touchpad is up. By a corresponding swipe on the touchpad can the selected Field, the change being independent of where the user is puts his finger on the touchpad. Crucial for the change is the direction and the length the swipe on the touchpad, with the highlighted and selected field is changed when a swipe movement in an alternating direction with a prescriptive length is detected on the touchpad. In addition, the operation in an advantageous Way at any time and at a later date to be continued.

In an embodiment of the operating system, the possible alternating directions for the sliding wiping movements on the touchpad for selecting and / or activating one of the entries advantageously correspond to the alignment of the entries displayed in an activated display area and the direction of the sliding wiping movement to leave the active display area is in each case for aligning the displayed entries orthogonal, the entries preferably being arranged in horizontal and / or vertical lists and / or menus. As a result, it is advantageously possible to change the selected entries intuitively within lists or submenus displayed on the screen display, and by means of a swipe movement on the touchpad surface which is orthogonal to the list or menu direction, the corresponding list or the corresponding menu to Close and / or change the main movement direction within intersecting lists or menus. Therefore, the touchpad can also be used to operate multi-dimensional, matrix-like menus.

In Another embodiment of the operating system, the length of the For example, wiping between placing it on the touchpad and the lift off the touchpad and / or a detected end of the swipe movement and / or a detected reversal point of the wiping movement direction determined.

That's why the touchpad is also on stored on a switch, over which the printing operation be executed can. By the pressure actuation can new ones Lists or new submenus open and closed. additionally can by repeated pressing, for example, double press, more Functions triggered become. In addition, the pressure operation be implemented so that between a long and a short printing operation can be differentiated to trigger different functions.

The Fields with the entries in the individual display areas are, for example, as vertical List in a y-direction of an xyz-coordinate system and / or as a horizontal list in an x-direction of the xyz coordinate system arranged, the pressure actuation in the z direction of the xyz coordinate system.

In Another embodiment of the operating system is the sensitivity of the touchpad by changing the required field change path length and / or the required Berührkraft context-dependent adjustable. As a result, the operating safety optimally to the adjusted menu structure become. So can these parameters for different Menus and / or Lists and / or directions of movement can be made variably adjustable.

By the touchpad sensitivity is determined, for example, the number of list entries or menu entries, which the mark of the selected Entry while painting jumps further from a given field change path length.

So For example, the sensitivity of the touchpad may vary from the scale the presentation can be set on the screen, in particular in the map display of a navigation application.

Additionally or Alternatively, the sensitivity of the touchpad in case of a change the direction of change initially be reduced. Through this "hysteresis" when changing the Actuation direction may be incorrect operation be avoided.

at an additional one or alternative embodiment of the operating system can be used for a field change required route length of the number of alternating direction arranged fields with entries and / or on the number of field changes already carried out during an actuation process and / or from a required contact force dependent be.

5 to 8th in each case a schematic representation of a mask for a touchpad 1 ,

How out 1 can be seen, includes the operating system 100 for a vehicle a screen display 200 , a manual designed as a touchpad actuator 300 , an evaluation and control unit 400 as well as others to the evaluation and control unit 400 connected input or output units, such as a voice control system 500 , more manual actuation 510 . 520 , which are embodied for example as hardkeys, and / or an acoustic output channel 530 , About the control system, not shown vehicle systems and / or applications, such as a navigation system, a heating and air conditioning, a mobile phone, a video system, an audio system, etc. are operated. The vehicle systems transmit signals to the evaluation and control unit 400 which make up the control and evaluation unit 400 Current system states determined.

The individual components 200 to 530 of the operating system can be arranged separately from each other, so that both the screen display 200 as well as the touchpad 300 and the other input and output units 500 to 530 can each be arranged at an ergonomically optimal position.

Like from the 2 to 4 can be seen with the touchpad 300 Posts 11 to 57 . 1.1 to 7.3 in the corresponding fields on the screen 200 are arranged in a menu structure with multiple menu levels selected and / or activated. The entries 11 to 57 . 1.1 to 7.3 represent applications and / or functions and / or sub-functions and / or options and / or status indicators in various menu levels of a menu structure. How out 2 can be seen on the screen 200 several display areas 10 to 50 to display the menu structure, wherein in at least one of the display areas 10 to 50 a selected field 23 is marked. A change of the selected field 23 on the screen 200 is done by a corresponding from an attachment point on the touchpad 300 independent, sliding wiping movement with a specifiable contact force on the touchpad 300 in an alternating direction, with the selected field 23 is changed when the sliding wiping movement mindes at least one field change path length exceeds.

For example, in the field 22 to the left of the currently selected field 23 changed when on the touchpad 300 a wiping movement is carried out from right to left, being between a touchdown point on the touchpad 300 and a lift point from the touchpad 300 is a track length which corresponds to at least one required field change path length, ie it is at a wiping movement in the negative x direction of an xyz coordinate system on the touchpad 300 a field change in negative x-direction made on the screen.

Will on the touchpad 300 a swipe is performed from left to right, then in the field 24 right of the currently selected field 23 changed when the length of the wiping movement corresponds to at least the required field change path length, ie it is at a wiping movement in the positive x direction on the touchpad 300 a field change in the positive x direction made on the screen.

Will on the touchpad 300 a sweeping movement is carried out from bottom to top, ie in positive y-direction, then the current on the screen 200 active viewport 20 leave that as a horizontal list with the entries 21 to 25 is executed, and the viewport 10 is activated, which is above the viewport 20 arranged and as a horizontal list with the entries 11 . 12 is executed. As selected field in the first viewport 10 , for example, the field 11 be marked. To change the display areas, the route length of the wiping movement corresponds to at least the required field change path length, ie it is in a wiping movement in the positive y direction on the touchpad 300 a field change in the positive y-direction on the screen 200 performed.

Will on the touchpad 300 a swipe is performed from top to bottom, ie in the negative y direction, then the current on the screen 200 active viewport 20 leave and the viewport 30 is activated, which is below the viewport 20 is arranged. As a selected field in the illustrated embodiment, the entire display area 30 be marked. To change the display areas, the route length of the wiping movement corresponds to at least the required field change path length, ie it is in a wiping movement in the negative y direction on the touchpad 300 a field change in the negative y direction on the screen 200 performed.

For each wiping movement whose route length corresponds to the field change path length, a field change is made. Thus, several field changes can be made without lifting the finger by the wiping movement is carried out over a longer Stecke. For example, by a longer wiping movement in the positive x-direction of the selected field 23 in the field 25 can be changed and by a longer wiping movement in negative y-direction over the fourth display area 40 in the fifth display area 50 change.

Additionally or alternatively, the distance of the wiping movement between the placing on the touchpad 300 and a detected end of the swipe or between placing it on the touchpad 300 and a detected reversal point of the wiping movement direction are determined.

The activation of the selected entry associated with an application and / or a function and / or a subfunction and / or an option 23 of the active display area 20 is done by at least one push of the touchpad 300 perpendicular to the touchpad surface in a negative z-direction, which is directed into the plane of the drawing, wherein the applied operating force is greater than the contact force for performing the wiping movement.

The touchpad can be of any size, with a size of 6 × 5 cm to 3 × 2 cm has been found useful. To perform the print operation, the touchpad is additionally mounted on a switch. The switch is activated by pressing the touchpad 300 triggered against a spring force at any point. The activation of the selected entry 23 can be reached by briefly tapping the touchpad 300 take place, by a repeated tapping, in particular two taps, a separate function can be triggered. In addition, the print function can be implemented so that a distinction can be made between a long and a short press.

to Implementation of the invention may be any touchpad technology used, which is able to detect a wiping movement and a track length and / or a contact force to investigate.

The sensitivity of the touchpad 300 can by changing the required field change path length and / or the required contact force context dependent on the evaluation and control unit 400 be set, ie for a change of the selected field 23 required stre Length can be programmed differently depending on the active application and / or function and / or subfunction and / or option. In particular, it may be useful for many entries in a vertical and / or horizontal list, a higher sensitivity of the touchpad 300 to program as with a few entries.

The sensitivity can be adjusted, for example, such that a wiping movement over the entire length of the touchpad 300 in the x direction of a total length or a half of the total length of the list in the x direction on the screen display 200 equivalent. Alternatively, a swipe can be made over the entire length of the touchpad 300 in the x direction of a predetermined number of fields in the X direction on the screen display 200 correspond. Analogously, the sensitivity can be set over the entire length of the touchpad in the y direction.

In addition, the sensitivity of the touchpad 300 from the scale of the display on the screen 200 be dependent, for example, when displaying a navigation map of the scale of the map shown. In addition, the sensitivity of the touchpad 300 become smaller with a change of the direction of change and become larger in a continuous wiping movement in the same direction of change, that is, the required field change path length is smaller.

To improve operating safety, the required field change path length and / or the required contact force on the touchpad 300 be set for a first field change in one direction of change greater than for subsequent field changes in the same direction of change.

To make a repeated sweeping over the touchpad 300 to avoid long vertical or horizontal lists in the illustrated embodiment, a field repeat function is implemented, which continues to perform a field change in the sense of the entered direction of exchange until a lift and / or change the direction of change is detected and / or the end of the vertical list 61 . 62 . 63 and / or the horizontal list 10 . 20 . 50 . 71 to 77 is reached. The field repeat repeat function is triggered by the fact that after a swipe in an alternating direction on the touchpad 300 and one on the screen 200 made field changes of the fingers on the touchpad 300 remains on hold. If the user reaches a border area during a swipe motion 301 of the touchpad 300 and leaves the user's finger on the touchpad edge 301 lie, then the list 61 scrolled further until the end of the list reached, the finger from the touchpad 300 is lifted off or moved in a different direction. Additionally or alternatively, the field repeat function is triggered by a further swiping in the opposite direction when on the screen 200 a fringe field 7.1 is selected in the direction of change and in the direction of other entries are selectable.

3 shows such a vertical list 61 with seven entries 1.1 to 7.1 of which the entry 7.1 is selected in a fringe field, as indicated by the hatched representation. By the arrow below the list 61 will indicate that there are more entries not on the screen 200 can be represented. The user now performs a swipe on the touchpad 300 in the direction of the arrow, ie in the negative y-direction, which is required to mark this on the subsequent field, then both in a further wiping movement as well as by leaving the finger the list 61 Continue scrolling to the bottom of the list 61 reached, the finger from the touchpad 300 is lifted off or moved in a different direction.

The described touchpad 300 can be coupled with other operating functions, such as with a "wrap around" function for lists, in which at the end of the list is jumped back to the top of the list.

How out 4 can be seen with the touchpad 300 matrix-like constructed menus are served, where the entries 1.1 to 7.3 on the screen in three vertical lists 61 . 62 and 63 or in seven horizontal lists 71 to 77 are arranged. The arrows at the edge of the screen 200 indicate that the associated lists 61 to 63 and 71 to 77 in the direction of the arrow still have other entries not shown. In the illustrated embodiment, the entry 3.2 in the vertical list 62 or the horizontal list 73 selected. A change of the selected entry takes place, as already stated above, by a corresponding wiping movement on the touchpad 300 in the desired direction of change.

The operating system additionally includes an acoustic output unit 530 and a haptic output unit, not shown, in the region of the touchpad 300 is arranged and outputs via specifiable pressure points and vibrations corresponding feedback to the user. For example, the user receives sufficient contact force on the touchpad 300 a corresponding haptic feedback. In addition, the user receives after a successful field change an audible feedback on the acoustic output unit and by changing the mark on the screen 200 a corresponding optical Feedback.

In the operating system according to the invention, at least one field is always marked in operation in at least one display area, regardless of whether the user has a finger on the touchpad 300 lying or not. The marker will only be changed if a corresponding swipe on the touchpad 300 is recognized, which triggers a field change. As a result, the user always advantageously receives a direct feedback about the current position within the menu structure.

to Prevention of incorrect operation can certain directions on the touchpad are disabled, i. these Barrier areas are not evaluated when evaluating the wiping movement. Becomes For example, only one horizontal and one vertical direction admitted, then, for example the angular ranges of 45 ± α, 135 ± α, 225 ± α and 315 ± α are not evaluated become.

The blocking areas can be, for example, by at least one on the touchpad 300 Applicable mask 320 . 340 . 360 . 380 be covered, whereby at the same time certain directions of change on the touchpad 300 pretend. The 5 to 8th show various embodiments of such masks 320 . 340 . 360 . 380 , The mask 320 out 5 allows only a vertical or a horizontal swipe on the touchpad 300 , The mask 340 on 6 allows only a circular swipe on the touchpad 300 and the mask 360 out 7 allows only diagonal wiping movements. By means of such masks arbitrary alternating directions can be specified, such as through the mask 380 out 8th is clarified. The mask 380 indicates a horizontal and / or a vertical and / or a diagonal and / or a circular direction of change. The circular alternating direction can be used for example for zooming in or out of a screen display and / or for selecting circularly arranged entries.

To release or cover the touchpad 300 can the masks by a relative movement of the touchpad 300 removed and / or placed in a covering position. The masks promote intuitive operation and avoid incorrect operation or unwanted contact.

If required, the masks can be folded down or moved away, for example, for "mouse operation" or character input.Additionally, the masked-out touchpad areas can be used for special functions, such as buttons above the touchpad 300 be placed on the touchpad 300 Press or with your own contacts above or below the touchpad 300 are arranged and for example via plunger through the touchpad 300 be operated. Alternatively, the masked areas can be represented by a frame, wherein a pressure within the frame on the touchpad 300 the respective special function is triggered.
