Abstract:
An operator control element system for a vehicle has an operator control element. The operator control element has a plurality of operator control areas and a region which faces an operator and a region which is located in a vehicle trim panel. The operator control element is distinguished in that it is mounted such that it can pivot about a rotation axis.

CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is based on and hereby claims priority to International Application No. PCT/EP2012/004392 filed on Oct. 19, 2012 and German Application No. 10 2011 118 723.9 filed on Nov. 16, 2011, the contents of which are hereby incorporated by reference. 
     BACKGROUND 
     The present invention relates to a control element. 
     With the generic control element disclosed in DE 103 43 134 A1 the control element is fixed in position and joined to the surface of a vehicle panel so as to be approximately flush therewith. 
     SUMMARY 
     One potential object is to provide a control element with simple operation and a wide range of uses. 
     The inventors propose a control element system in which the control element is mounted so as to pivot about an axis of rotation that is parallel to a surface of a vehicle panel. The pivot angle is thereby preferably between 5 and 30°. With such an embodiment of the control element it can be used at any point in the entire interior paneling of the vehicle, which extends the use of control elements in vehicles. 
     In one embodiment the region of the control element disposed in the vehicle panel is mounted between operation detection sensors. Thus the region of the control element disposed in the vehicle panel presses against a sensor that detects an operation when the control element is operated by an operator, which causes pivoting of the control element about the axis of rotation, and the sensor generates a sensor signal. Advantageously, the operation detection sensors are in the form of pressure sensors, whereas of course other sensors are also conceivable as operation detection sensors. With this embodiment, an easily handled control element results that functions similarly to a piano key. 
     Advantageously, the region of the control element facing the operator protrudes out of the surface of the vehicle panel. It is particularly advantageous if the protrusion lies in the range from 3 cm to 8 cm. This design of the control element increases the accessibility to the control element and thus also improves operability. 
     In an alternative embodiment an actuator is integrated within the control element, which imposes a movement on the control element when the control element is operated by the operator and thus produces tactile feedback to the operator. The actuator can e.g. be an electromagnetically driven actuator here. When the control element is operated an operation signal is passed to a control unit from the operation sensors. The control unit passes said operation signal to the actuator and triggers it. 
     Advantageously, the control fields, which can e.g. be in the form of press buttons or touch-sensitive surfaces, are disposed on the top and/or the bottom of the control element. With the control fields disposed on the top and the bottom of the region of the control element facing the operator, it is particularly advantageous if complementary control functions such as e.g. “increase volume” and “reduce volume” are disposed opposite each other, i.e. “increase volume” on the top and “reduce volume” on the bottom of the region of the control element facing the operator. The intuitive operation of the control element is improved with such an embodiment of the control element. Of course, the control fields can also have other associated functions, such as e.g. temperature regulation, ventilation regulation or radio transmitter. 
     In another embodiment the control element is disposed on a side wall of a central console or on a vehicle door. 
     Advantageously, the region of the control element facing the operator has a drop-shaped cross section. 
     In another embodiment the control element is in the form of a bar or of a lever. 
     The control element can be made of a plastic or a metal such as aluminum. In order to improve the presentation of individual control fields of the control element, it can be provided that the surfaces (in the case of plastic), which normally includes a dark cover layer, are lasered out at the control field borders and a light source such as e.g. an LED or OLED is integrated within the control element. Such an embodiment causes illumination of the border regions of the control fields. An indirect light feed by optical fibers into the control element is also conceivable, in order to be able to illuminate the border regions of the control fields.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. 
     In the sectional view of  FIG. 1  the control element  1  comprises a region  2  facing the operator that protrudes out of the vehicle panel  6  and a region  3  disposed in the vehicle panel  6 . Here the region  2  facing the operator protrudes by 3 cm to 8 cm from the vehicle panel  6 . The control element  1  is mounted so as to pivot about the axis of rotation  4 , which runs parallel to a surface  7  of the vehicle panel  6 . The pivot angle by which the control element pivots is in the range from 10° to 25° in this case. The region  3  of the control element  1  that is disposed in the vehicle panel  6  is mounted between operation detection sensors  5 . 1 ,  5 . 2 . If the operator presses on a control field  12 . 1 ,  12 . 2 ,  12 . 3 ,  12 . 4 ,  12 . 5 ,  12 . 6  on the top  8  or the bottom  9  of the region  2  of the control element  1  facing the operator, then the control element  1  pivots about the axis of rotation  4  of the control element  1 . As a result of said pivoting motion the region  3  of the control element  1  disposed in the vehicle panel  6  presses with one side  10 ,  11  on the operation detection sensors  5 . 1 ,  5 . 2 , which are in the form of pressure sensors. The side  10 ,  11  that presses on the operation detection sensors  5 . 1 ,  5 . 2  depends on whether a control field  12 . 1 ,  12 . 2 ,  12 . 3 ,  12 . 4 ,  12 . 5 ,  12 . 6  of the top  8  or of the bottom  9  of the region  2  of the control element  1  facing the operator is operated. If a control field on the top  8  of the region  2  of the control element  1  facing the operator is operated, the side  10  of the region  3  of the control element  1  disposed in the vehicle panel  6  presses on the operation detection sensor  5 . 1 . If a control field on the bottom  9  of the region  2  of the control element  1  facing the operator is operated, then the side  11  of region  3  of the control element  1  disposed in the vehicle panel  6  presses on the operation detection sensor  5 . 2 . The operation detection sensors  5 . 1 ,  5 . 2  pass the operation signal to a control unit that is not shown, which then carries out the corresponding control function and controls an actuator  21  disposed in the control element  1 . The actuator  21  produces tactile feedback to the operator when controlled by imposing on the entire control element a movement along the axis of rotation  4  of the control element, which can be detected by the operator. 
       FIG. 2  shows a plan view of the region  2  of the control element  1  facing the operator. A plurality of control fields  12 . 1  to  12 . 6  with different control functions is disposed on the top  8  of the region  2  of the control element  1  facing the operator. Here the control fields  12 . 1  to  12 . 6  are occupied by “positive” control functions such as e.g. increase volume, increase temperature, increase ventilation, or switch on the interior lighting.
