Abstract

The invention relates to a steering wheel switch module for a motor vehicle for integration into a stored steering wheel (1) of the motor vehicle with at least two multi-key control switch assemblies (5, 6, 7, 8), wherein the steering wheel switch module (100) as a whole vorgefetigt in the steering wheel (1) - and is removable.

Description

The The invention relates to a steering wheel switch module for a motor vehicle according to the preamble of claim 1.

operating devices in the form of switches, buttons, rotary switches, toggle switches and The like are necessarily used in motor vehicles. Here are simple switching elements, either on rotary or Push-action or on a simple tilt-lock operation based, used only for such device, the only know the switching states "on" and "off".

Besides However, in automobiles are often electronic devices used, which does not operate autonomously, but the appropriately controlled can or must be. These are more complex Operating devices necessary, including often a multiple Arrangement of individual switches and switching elements or operating elements correlate with each other.

To Come that the plurality of operating devices for the large number of devices on dashboards and steering wheels are difficult to accommodate. As a consequence of this the controls must be kept small, which on to a bewildering variety of control buttons, buttons and switches similar or similar construction leads.

In addition, as already mentioned, increasingly electronic devices, such as the now widely used navigation system and driver assistance functions and the separate influence or influenceability of the safety devices or other devices in the motor vehicle by switching elements actuated. For this purpose, multifunction operating devices are often used, which are also mostly menu-driven. A corresponding device for the central display of vehicle-related data is for example from EP 1 195 299 B1 known.

A further application of modern vehicle information technology exists in it, the driver in the operation of a vehicle by the demand-oriented Provision of on-board information and operating instructions. In this way, the driver can, for example, on reading a voluminous Manual waive and still all in his vehicle operate the provided functions correctly.

These However, a variety of facilities to use also runs the risk of that the driver is distracted from the traffic and thus the risk of accidents is greatly increased. Thus exists the need to design the controls as intuitively as possible.

In addition, it is known to also output information auditory, so that the driver is not visually distracted. A corresponding system is for example from the DE 101 26 673 A1 known. This system uses a multifunction steering wheel with push buttons to operate the system without letting go of the steering wheel.

From the DE 100 03 610 A1 is known an operating device for electrical / electronic devices in motor vehicles, in which a rotary actuator and a tilting operation is provided, wherein only a common operating element is provided for this purpose. It is a joystick-type billet, which in addition to the usually known tilt function additionally allows rotation about its own axis.

The DE 199 41 947 A1 discloses a steering wheel having integrated controls that can be configured as a bidirectional rotatable roller or as a cross-rocker switch, wherein the roller can be additionally designed to be movable perpendicular to the longitudinal or rotational axis of the roller, so can be pressed. The controls are assigned to the steering wheel spatially the respective instrument to be controlled.

The DE 198 07 410 A1 discloses a multifunction control device for selecting and controlling a plurality of functions comprising a display, function keys, which is associated with a fixed function, the flow control can be influenced by displayable softkeys on the display, and at least one control panel dedicated functionality. The function keys are partially freely programmable and associated with at least one two-dimensional menu selection switch of the multifunction control device. In addition, an embodiment includes four cross-function keys, in the middle of a rotary switch is arranged.

The DE 102 12 781 A1 describes a vehicle steering wheel with at least one arranged on this switch, which can be operated in at least two substantially mutually perpendicular directions, ie horizontally and vertically, wherein the switch or button is arranged on a memory of the steering wheel. It is further provided that the switch is moved and / or rotated. In addition, the switch can additionally act as a pressure switch, so that it can be pressed as a whole perpendicular to the plane of the steering wheel.

Another steering wheel, the switch to Be Servicing of vehicle functions is out of the EP 1 046 565 A2 known. Each switch works simultaneously as a rotary switch and as a pressure switch, the switch automatically adjusts itself centrally in the unactuated state. In addition, it can be seen from the description that several separate switches are individually embedded in the steering wheel at different positions.

The above switch, facilities and steering wheels have all the disadvantage that they are relatively complex assembly and Dismantling operations bring with it.

task The invention is a steering wheel switch module for a Motor vehicle for integration in a stored steering wheel of the motor vehicle To provide that built as easy as possible assembly is provided by the supplier with a high degree of prefabrication can be. It should nevertheless the selection as well as the control individual vehicle-related functions allow, while an ergonomic meaningful and intuitive operation of vehicle-related functions allow and in addition the driver in his attention affect as little as possible. Furthermore, should the operator switch assembly is for menu control of modern vehicle information and operation systems, such as As music system, speed controls and navigation systems. In addition, the operating switch arrangements of the Steering wheel switch module as little space in the vehicle claim and ultimately be simple.

These The object is achieved by the recited in claim 1 steering wheel switch module solved.

Thereby, in that the steering wheel switch module for a motor vehicle for integration into a stored steering wheel of the motor vehicle with provided at least two multi-key control switch assemblies is, wherein the module is designed such that it as Whole prefabricated in the steering wheel is removable and expandable, it is possible to install the steering wheel switch module easy to install and with a high degree of prefabrication provided by the supplier. It can therefore be used in the final assembly with a few simple steps with no complex processes necessary. At the same time, several operating switch arrangements are simultaneously being made installed in the respective steering wheel, so that despite the simplification the assembly or disassembly not on the selection and the control a variety of vehicle-related functions is omitted.

Logically, To do this, the multi-key switcher arrangements on one common base plate built. It is favorable if the common base plate the screen of the control switch assemblies or the steering wheel switch module is, so that additional Parts can be saved.

In a preferred embodiment connects the screen the spokes of the steering wheel. This allows an ergonomic meaningful and intuitive operation of vehicle-related functions reach and also the driver is due to this placement the operating switch arrangements in his attention as possible little affected.

The Ergonomics will be even better if the screen is the spokes connects the steering wheel while one of the Bedienschalterschalteranordnungen a spoke and the other operator switch assembly between the spokes is arranged. So can more often used functions via the one control switch assembly be driven on the spoke, the most visible there and is reachable. More features will be over the other Serving switch assembly, which is also easily accessible is placed. In addition, the space on the steering wheel, which is also limited is present, since usually in the middle part of the steering wheel, an airbag is provided, well used.

A further simplification of assembly and improvement of rationalization achieved when the Bedienschalteranordnung also as a separate Modules are formed, so the steering wheel switch module itself modular is.

The individual modules, so the switch switch arrangements can over Locking means with the steering wheel switch module connectable or to this be configured composed, in particular with the common Baseplate.

Around to simplify assembly and disassembly and to avoid errors is provided in one embodiment that the Control switch arrangements for electrical / electronic coupling have separate sockets. These are advantageous physically coded so that they are not confused. So they can stand apart from each other in different colors have distinctive shapes, so that only a single correct plug connection is possible in each case.

The control switch assemblies provided with the steering wheel switch module are suitable for menu control of modern vehicle information and control systems, such as vehicle control systems. As music system, speed controls and navigation systems. Thus, despite a lot number of possible functions that are to be operated via the operating switch arrangements, as compact a structure as possible can be achieved.

To can the one operating switch arrangement with four switching elements, which are arranged in a cross shape, and with another Switching element, which is arranged centrally relative to the four switching elements is provided, wherein the four switching elements cross-shaped are arranged around the central further switching element and the switching elements in such a way are executed that they can be operated separately from each other are and that a further switching element, in particular annular, surrounding common rocker switch is provided over the four switching elements are actuated separately, wherein the other switching element regardless of the four switching elements via a separate button is executed operable.

So It is an intuitive way for the driver of motor vehicles Give control unit to the hand, which is compact and easy is constructed and located next to the operation of electrical / electronic Devices (eg radio, air conditioning etc.) especially for the menu-based prompting and / or Control of modern vehicle information and operation systems is suitable and yet easy to assemble or disassemble.

Under "annularly surrounding" should not alone a circular one Arrangement of the rocker switch to understand the central switching element around be. There are also oval, elliptical, rectangular, square, diamond-shaped and the like arrangements of the rocker switch in question.

By the cross-shaped arrangement of the switching elements and the operation of the four "outer" switching elements over a common rocker switch will provide the intuitive and ergonomic operation of the Devices or systems ensured. So it is for the Driver especially easy to maneuver through menu systems and electronic or electrical devices, such. Legs Music system to use. This is still due to the separate operation possibility amplified the switching elements.

By the cross arrangement of the four switching elements and their corresponding operation keys can be virtually imaginary Mimic directions of movement "left-right" and "up-down", which gives the user an ingenious logic regarding the Operation of many functions is. This is true for. B. on the volume control or station selection of a radio, CD player, etc. This is also true for navigation in hierarchically arranged menus to, where a movement of a control cursor "up-down" the Run through points in a menu list while "left-right" menu levels changes. These are only two many examples that are feasible with the invention.

There the other switching element regardless of the four switching elements via a separate button is executed operable, This central button then serves z. B. for easy implementation, Selection, acknowledgment or confirmation of commands, change of controlled devices etc.

The other control switch assembly can this purpose at least three switching elements two of which together form approximately the shape of a "C" and the third switching element is disposed within the legs of the "C" is. In addition, it can be a fourth and fifth switching element have, from other switching elements laterally and below are arranged. The fourth and fifth switching element can over executed a common rocker button actuated be.

advantageously, becomes an electric with the one operation switch assembly and / or electronic device, in particular music system, and / or a hierarchical menu of a device for display and Control of motor vehicle-related functions is in the vehicle operated / controlled. With the other control switch assembly is then a Fahrzeuggeschwindigkeitsregelvorrrichtung (cruise control) operated / controlled.

there can be performed by one or more switching elements Functions with the respective switching elements are assigned permanently. This is z. B. useful for particularly important functions, such as the volume control, preferably the opposite Assigned "up-down" pair of switching elements of the four switching elements is. So in every situation it is guaranteed that these in vehicle operation with most frequently used function always is ready.

alternative One or more switching elements can be designed in this way be that the functions assigned to them freely programmable are. In many vehicles functions are also over nowadays Logic units, microcontrollers or microprocessors etc. controlled, which are programmable. This also applies to the over the switching elements to be triggered or operated functions to. Thus it is possible within the scope of the invention individual or several switching elements with certain functions to occupy, for. With favorites or frequently used functions. Of the Driver or user can so his own turned off and customizing the control system.

Alternatively, one or more switching elements can be designed such that the supplied them These functions change depending on the context. This makes it possible to control a variety of functions with a few switching elements. So z. B. the "left-right" switching elements in radio operation to control the station search in the respective direction, cause the change of titles in CD mode or cause a cue operation forward or rewind. The central switching element can, for. B. in an incoming phone call to effect its acceptance and effect the termination during the call or the connection. On the other hand, if the radio plays, it could be provided that the normal context-dependent function of the station selection or programming is temporarily changed to the call acceptance described.

additionally can the switching elements be designed in such a way that they depend on their duration of operation assigned to different functions. This also allows to use the limited space in the vehicle sparingly and to operate several functions via a switching element. So can with a short operation another function be triggered than during a long operation or a permanent operation. So could one short press the central button a current station search stop on the radio while a long press the central button to switch the radio to the CD player, So a cyclic switching all with the switch assembly could cause controllable devices, the Release the currently selected device selects.

In spite of the sometimes particularly sophisticated turn-tilt-pressure switch the prior art, which involves a simultaneous rotation, Tilting or pressing a switching element as possible perform many functions, it has been found that the switching elements It makes sense to be simple pressure switches, which may be multi-stage switches. These switches are easy to operate and guide the driver least and are also robust and simple. Multi-stage switch offer the possibility depending on actuation path the switch to trigger various functions.

So the switching elements can have plungers, which act on a contact mat approximately perpendicular to the actuation to close or open a contact.

In order to only one function is executed despite the common rocker switch is the operation switch arrangement can be carried out in this way be that only one function at a time by the common rocker switch is triggered. This is in a preferred embodiment provided that the operating switch arrangement forced control means having. These can be considered at the back of the Rocker button trained guide tappet and corresponding guide openings formed in a housing part be educated. It is beneficial if the leadership breakthroughs are cross-shaped in cross section.

Becomes So at z. B. while driving by the user the common rocker button not exactly at the pressure point of one of the switching elements pressed, but about between two of these, z. B. by Pressure on a corner of the rocker switch, so it is still only a function triggered, since the precautionary means ensure that the rocker button ultimately only in one of the switching directions can move successfully.

The complete operating switch assembly can also be constructed as a module so that it is in and out of maintenance as a whole.

are one or more switching elements designed such that the change functions that are performed with them depending on the context, can be the most commonly used in an intuitive way Function "placed" on the respective switching element.

on the other hand can also be performed by one or more switching elements Fixed functions with the respective switching elements or be wired so that particularly important functions, as the volume control is always available stand.

If one or more switching elements are designed in such a way that their assigned functions are freely programmable an adaptation of the operation to the preferences of the driver is possible. This also allows a change in the functions when z. B. another device is newly installed in the vehicle or a new "software" version is played.

Becomes monitors the duration of operation of one or more switching elements, so may vary depending on it Functions are triggered, what a simple way multiple assignment of the switching elements allowed. So can a short Actuation of the central switching element effect a selection (see above), whereas a longer operation Jump back to a basic menu or reset or zeroing certain functions.

Further Features, details and advantages of the invention will become apparent the following description of an embodiment based on the drawing. Show it:

1 a plan view of a steering wheel of a Passenger vehicle with the steering wheel switch module according to the invention and

2 an exploded perspective view of the items of the steering wheel switch module 1 ;

With reference to the figures, the structure and the use according to the invention of the steering wheel switch module 100 or whose Bedienschalterschalteranordnungen explained.

In 1 is a steering wheel 1 a passenger car in a plan view, which has a circular steering rim 2 has, over four spokes 3 with a middle part 4 connected is. About the middle part 4 usually becomes the steering wheel 1 Connected to the steering column and it usually houses an airbag.

Usually, the steering wheel 2 grasped by the fingers, with the palm of your hand thus on the steering wheel 2 rest the thumbs roughly on the upper spokes 3 resting in the area of the transition of the spokes 3 to the middle part 4 ,

Between the respective left and right spokes 3 is a steering wheel switch module 100A , B provided. The modules 100 connect the spokes, so to speak 3 , with a part on / in the upper spoke 3 is arranged, a part parallel to the middle part 4 between the spokes 3 runs and a part on / in the lower spoke 3 is arranged. The steering wheel switch modules 100 are arranged approximately mirror images of each other.

Each steering wheel switch module 100 includes a switch assembly 5 respectively. 6 at the upper spoke 3 and another switch arrangement 7 respectively. 8th parallel to the middle part 4 between the upper and lower spoke 3 ,

Each switch arrangement 5 respectively. 6 includes a central switching element 9 . 10 that's over in the 1 visible button is actuated. Cross-shaped around this central switching element 9 respectively. 10 each are four other switching elements 11 . 12 . 13 . 14 respectively. 15 . 16 . 17 . 18 arranged, via a common visible rocker switch 19 . 20 are separately actuated, the central switching element 9 . 10 or whose key surrounds. The rocker switch 19 . 20 surrounds the key of the central switching element 9 . 10 roughly square with rounded corners, with the upper and lower sides of the square slightly tapering outwards in accordance with the spokes 3 to run.

Hereinafter, for simplicity, reference will be made to the switching elements themselves, it being understood that in 1 only their operation buttons are visible.

The respective opposite switching elements 11 . 13 and 12 . 14 respectively. 15 . 17 and 16 . 18 each form a pair of opposing function associated with vertical and horizontal directions, as will be described later. Their buttons are also marked with corresponding symbols.

Each additional switch arrangement 7 respectively. 8th initially comprises three switching elements 21 . 22 . 23 respectively. 24 . 25 . 26 , of which also only the operation buttons in 1 are visible. Here are the upper and lower switching element 21 . 22 respectively. 24 . 25 arranged or shaped approximately C-shaped and the respective third switching element 23 respectively. 26 is located between them within the "C".

In the present case, the left has further switch arrangement 7 still a fourth and fifth switching element 27 . 28 on, the laterally below the first three switching elements 21 . 22 . 23 are arranged and via a common rocker switch 29 are operable.

All Switching elements are pressure switches and designed in such a way that they are operated separately from each other. Furthermore, their keys have nubs, bars or similar Structures that find their pressure point without visual Allow feedback.

All Switching elements are monitored by a microprocessor, not shown, so that their duration of operation can be determined and depending on it different functions per Switching element are executable. In addition, the microprocessor allows a programming or modification of the function of the respective Switching element, possibly also context-dependent.

The switch arrangements 5 respectively. 6 and other switch assemblies 7 respectively. 8th are each as a single module 200 respectively. 300 built so that these prefabricated to the steering wheel switch module 100 can be assembled. This and the structure of the steering wheel switch module 100 from the modules 200 . 300 is related to 2 described below.

In the 2 is a module 100 shown in detail. In this case, it is the left module 100A , It is understood, however, that the right module 100B is constructed analogously.

First, the structure of the module 200 the switch assembly 5 described. The switch arrangement 5 includes a housing base 30 connecting to the steering wheel 1 provides. Into the hous sebasis 30 is a circuit board 31 used, which carries a possible evaluation electronics or resistor cascade for the individual switching elements and contact pins for the connection to the other vehicle electronics. On this board 31 is a contact mat 32 hung up with pairs of contact elements 33 is provided, each associated with a switching element and at an operation, so a pressure, close a contact, so that the evaluation unit performs the operation of the respective switching element.

For actuating the contact elements 33 the four outer switching elements 9 - 14 are each ram 34 provided, which have a widened base, so that both contact elements 33 of a couple are depressed together. The contact elements 33 are designed so that they in addition to a pressure resistance and a resilient return of the plunger 34 cause.

The pestles 34 and the contact mat 32 be from a housing top 35 covered, which additionally guide breakthroughs for the plunger 34 has, so that this with the button above 19 can cooperate to actuate the contact elements 33 to effect. The rocker switch 19 has on its back in each case four actuating tappets, which with the corresponding plungers 34 interact.

The switch arrangement 5 is designed in such a way that only ever a function by the rocker switch 19 is actuated or triggered. So if z. B. while driving by the user the rocker switch 19 not exactly at the pressure point of one of the switching elements 11 - 14 pressed, but about between two of these, z. B. by pressing a corner of the rocker switch 19 , but only one function will be triggered. For this purpose, the switch arrangement 5 suitable forced guidance means.

These are also on the back of the rocker switch 19 In the corners guide tappet provided in corresponding guide openings in the upper housing part 35 intervention. The guide openings are cross-shaped in cross section.

In the rest position of a guide tappet in a guide opening, the guide tappet is located in the center of the cross-shaped guide opening. Now, the key is pressed between two pressure points, z. B. between the positions that the switching elements 11 and 12 correspond, so the upper right corner, the guide plunger will move obliquely in this direction to the top right and abut the side edge of the Führungsdurchbruchs between the arms of the cross, so that initially neither an actuation of the switching element 11 yet 12 takes place. However, as a rule, the pressure will not be exactly between the two switching elements 11 and 12 is exercised, but one of the two directions will always be somewhat preferred, that is, be subjected to a little stronger force. Therefore, the pressure of the rocker switch 19 tilt slightly in one of the directions so that the guide tappet is in the respective direction of the switching element 11 or the switching element 12 move within the guide aperture, whereby the corresponding switching element 11 respectively. 12 is pressed.

There Corresponding guide tappets in each corner and leadership breakthroughs are present always two guide tappets the above Perform movements to actuate one To reach switching element.

The rocker switch 19 is also with a central recess 36 provided so that this is the central button 9 can accommodate the central switching element. For the actuating plunger of the central button 9 is also an opening in the depression 30 intended.

The upper housing part 35 has a central guide opening or hollow mandrel 37 on, which has a spherical head on which the rocker switch 19 rests with a corresponding surface so that it is "rocking" in the direction of all four switching elements. Here is the central recess 36 so dimensioned that the central button 9 is not affected.

The key 19 is made of translucent plastic, so that it can be backlit. For this purpose, the board 31 two LEDs 38 on, passing through windows 39 in the contact mat 32 their light to a suitably constructed light guide 40 give the light then to the keys. For this purpose, the light guide 40 four cruciform arranged upwardly extending arms 41 . 42 on, two of which 41 each one window 39 are too ordered and so the light of the LED's 28 take up. These arms 41 Forward the light so that all four of the switching elements 11 - 14 corresponding positions of the rocker switch 19 are backlit. The key 9 is opaque on the other hand.

The other two arms 42 serve as guide elements and engage in the assembled state to corresponding guide openings in the upper housing part 35 one.

In addition, the light guide has 40 a second function and that of an actuating plunger for the central switching element 9 or their button. For this purpose, the light guide 40 a central thorn 43 up, through the hollow thorn 37 of the upper housing part 35 grips and on the button 9 sitting. Will the button 9 pressed, the light guide moves 40 as a whole down, so that the centrally arranged contact elements 33 over the two non-light-guiding arms 42 be operated. In the process, the light guide becomes 40 guided over the leadership breakthroughs.

The entire switch arrangement 5 is as a prefabricated module 200 installed. This is the module 200 initially by plugging the housing parts 30 . 35 and the remaining parts assembled and then in a common base plate 101 of the steering wheel switch module 100A snapped in and then with the module 100A in the steering wheel 1 used latching and bolted. In this case, the module has 200 a contact plug 44 at the bottom of the housing base 30 for connecting the contacts of the board 31 with the other vehicle electronics. The common base plate 101 is in the present case, the screen 101 of the entire steering wheel switch module 100A ,

Now, the structure of the further switch assembly 7 described. The switch arrangement 7 is also called a module 300 prefabricated, in the present example, the assembly directly on the common screen 101 of the entire steering wheel switch module 100A he follows. The structure corresponds to the module 200 the further switch arrangement 7 the just described technique for switch assembly 5 ,

The switch arrangement 7 So includes a housing base 46 into which a board 47 is inserted, on the turn an upper contact mat 48 with pairs of contact elements 49 put on and under the one lower contact mat 50 with pairs of contact elements 51 is underlaid.

On the upper contact mat 48 follows the common screen 101 , which in turn has suitable recesses for the keys, which are provided on its underside with actuating cams to the contact elements 49 on the upper contact mat 48 directly, ie without a plunger to operate. So the buttons 21 to 23 into a depression 45 on the screen 101 They can be clipped latching, they also have locking means on their underside 52 on.

On the bottom of the board 47 is the bottom contact mat 50 with contact elements 51 between the board 47 and the lower housing part 46 arranged so that the rocker switch 29 the fourth and fifth switching elements 27 . 28 on the operation of plungers 53 the contact elements 51 can close to close at contact, so a pressure, a contact, so that the evaluation unit perceives the operation of the respective switching element. The side rocker button 29 is due to a breakthrough 54 in the housing lower part 46 led to the outside.

The rocker switch 29 is similar to the rocker button 19 over a here Y-shaped light guide 55 backlit by an invisible LED 56 on the bottom of the board 47 is fed. Also the buttons 21 to 23 are with the help of appropriate LEDs 57 on the board 47 backlit, but due to the structure could be dispensed with the use of light guide.

Is the module 300 the switch assembly 7 on the common screen 101 constructed, the module described above 200 latching into the recess provided for this purpose 58 be used latching.

The finished steering wheel switch module 100A then gets into the steering wheel 1 used, screwed and fixed.

The respective switch arrangements 5 . 7 each have a separate integrated socket, which are connected to each other in the Lenkradendmontage via electrical lines, the connector housing are coded such that no mishaps is possible.

The following is the use of the above-described steering wheel 1 in a passenger car with a music system, a telecommunications system and a device for displaying and controlling of motor vehicle-related functions in the vehicle, in particular a navigation system / board computer and a cruise control described.

The switch arrangement 5 is used to operate the music system and the telecommunications system, so is a "multimedia disk switch". The further control switch arrangement 7 is used together with its right counterpart to operate a Fahrzeuggeschwindikeitsregelvorrrichtung or a cruise control, so is a "speed control switch". The right switch arrangement 6 is used to control / actuate a device for displaying and controlling vehicle-related functions.

In the present example, the left switch assembly is used 5 for controlling / operating the music and telephone system in the vehicle.

These are the vertical switching elements 11 . 13 the left switch assembly 5 Hardwired, ie permanently assigned to a specific function, regardless of the duration of the operation. In the present case, this is the volume control of a not illustrated set music system.

• – Im Radiobetrieb: Automatischen Sendersuchlauf in die jeweilige Richtung starten;
• – Im Kassettenbetrieb: Beginnen und Beenden des schnellen Vor- und Zurückspulens;
• – Im CD-Spielerbetrieb: Vor- und Zurückspringen zwischen den einzelnen Titeln;
• – Im CD-Wechslerbetrieb: Vor- und Zurückspringen zwischen den einzelnen Titeln der momentan ausgewählten CD;

The remaining horizontal switching elements 12 . 14 are assigned context-dependent, ie their function changes, depending on which device of the music system is currently in operation and is dependent on the duration of the operation. So have the horizontal switching elements 12 . 14 short press the following functions:

• - In radio mode: Start automatic station search in the respective direction;
• - In cassette mode: start and stop fast forward and rewind;
• - In CD player mode: jump forward and backward between the individual titles;
• - In CD changer mode: jump forward and backward between the individual tracks of the currently selected CD;

Appropriate Other functions are for MP3 players, minidisk players etc. conceivable.

• – Im Radiobetrieb: Kontinuierliches Durchlaufen der Radio-Frequenzen in die jeweilige Richtung solange die Wipptaste 19 gedrückt bleibt;
• – Im Kassettenbetrieb: Beginnen und Beenden des schnellen Vor- und Zurückspulens;
• – Im CD-Wechslerbetrieb: Kontinuierliches Durchlaufen der Abspielposition innerhalb des jeweiligen Titels der momentan ausgewählten CD in die jeweilige Richtung solange die Taste gedrückt bleibt;

In contrast, the horizontal switching elements 12 . 14 after prolonged operation, the following functions:

• - In radio mode: Continuous passage of the radio frequencies in the respective direction as long as the rocker switch 19 remains pressed;
• - In cassette mode: start and stop fast forward and rewind;
• - In the CD changer mode: Continuously scrolling the play position within the respective title of the currently selected CD in the respective direction as long as the key remains pressed;

Appropriate Other functions are for MP3 players, minidisk players etc. conceivable.

The central switching element 9 is wired and context dependent.

This is how the button is pressed for a long time 9 the switching between different devices of the music system causes. These can be analogous to above: radio, CD player, cassette drive, CD changer, MP3 player, mini-disc player, etc.

• – Im Radiobetrieb: Ändern der Vorauswahl (Preset?);
• – Im Kassettenbetrieb: Kassettenabspielrichtung ändern;
• – Im CD-Wechslerbetrieb: Vor- und Zurückspringen zwischen den eingelegten CD's;

With a short press of the button 9 On the other hand, a different function is executed depending on the device currently being used. A short press performs the following functions:

• - In radio mode: change the preselection (Preset?);
• - In cassette mode: Change cassette playback direction;
• - In CD changer mode: jump back and forth between the inserted CD's;

In addition, by briefly pressing the central button 9 an incoming telephone call can be accepted or a call is terminated when the connection is established.

In the present example, the right switch assembly is used 6 for controlling / operating a hierarchical menu displayed on a display of a device for displaying and controlling motor vehicle-related functions (not shown).

The Display is in the field of vision for ergonomic reasons Driver, preferably well visible centrally in the dashboard between the speed and speed display arranged. Thus, the Driver distracted as little as possible from driving and does not require major eye movements or head turns perform.

The Device is z. B. a conventional navigation / board computer system, besides navigation via GPS, etc. also consumption values, Range, outside temperature, current consumption, time etc. and the control / setting of other functions of the Vehicle allowed.

The Device for displaying and controlling motor vehicle-related Functions are controlled via the hierarchical menu, set and pressed. The menu includes a basic menu I and several menu levels II, III, IV, each with several list-like shown Menu items II.1, II.2, II.3 ...; III.1, III.2, III.3 ..., IV.1, IV.2, IV.3 etc.

The hierarchical menu is controlled by means of a cursor, set and actuated, in turn, by the switching elements of the switch assembly 6 is moved.

For cursor movement are the vertical switching elements 15 . 17 the right switch arrangement 6 Hardwired, ie assigned to a specific function, regardless of the duration of the operation. In the present case, this is the movement of the cursor through the menu items (eg IV.1, IV.2, IV.3, etc.) of a menu level, which are shown as a list one above the other. If the cursor arrives at a list above or below, it jumps down or up to the last or first displayed menu item. It thus moves intuitively cyclically through the displayed list in the direction of the respectively actuated key of a switching element, here 15 . 17 ,

The horizontal switching elements 16 . 18 Keys are also fixed, namely moving the cursor between menu levels, ie to the left of the previous higher-level menu (eg III + 1 = IV) or to the right to below lying lower-level menu (eg III + - 1 = II). Prolonged pressure causes the actuation of the left switching element 16 by means of the rocker switch 20 Jump back the cursor or the display in the base menu I regardless of the current cursor position.

The central switching element 10 is also permanently connected to a function. This will reset the displayed function during a long press. By way of example, the reset of the daily mileage counter or the average consumption are mentioned. In the case of a short press, on the other hand, a selection or acknowledgment of the function currently selected with the cursor on the display in the menu is carried out. So z. B. the switching of the standard language for the menu system of the display are acknowledged.

The further control switch arrangement 7 will be together with her right counterpart 8th used to operate and control a cruise control. The keys of the three switching elements serve this purpose 24 . 25 . 26 for controlling or adjusting the speed to be kept. Here are the buttons 24 and 25 with an increase or decrease in the set speed, whereas the key 26 acts as a reset button. The key 21 the left switch assembly 7 Serves to take over the speed that has just been driven by the speedometer as the speed to be maintained or as the default for cruise control.

In the present case, the cruise control is not only able to automatically maintain a set speed, but can also automatically maintain a distance to the vehicle in front or issue a warning if the distance falls below a predeterminable distance. This is the button 22 occupied with the function of assuming the currently maintained distance. The key 23 serves to turn off the distance control, z. B. in traffic. The via the common rocker switch 29 operable switching elements are used to reduce or increase the distance to the car in front.

It It is understood that a variety of variants and combinations are conceivable within the invention.
