## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is based on and hereby claims priority to International Application No. PCT/EP2010/007184 filed on Nov. 26, 2010 and German Application No. 10 2009 056 186.2 filed on Nov. 27, 2009, the contents of which are hereby incorporated by reference.
BACKGROUND
The following description relates to an apparatus for the operator control of at least one function of a motor vehicle and/or of at least one appliance installed in a motor vehicle.
An operator control apparatus is described in DE 10 2004 031 659 A1. In this case, an armrest includes a supplementary operator control element which complements an operator control element which is present in the dashboard. The supplementary operator control element may have a transparent touch-sensitive layer, beneath which further parts of the supplementary operator control element are arranged. However, although the touch-sensitive layer of the supplementary operator control element is transparent, it is not possible to perceive the underlying surface beneath the supplementary operator control element.
Another example of an apparatus is described in DE 103 04 704 A1 or DE 103 04 720 A1, for example. Such “touchpads”, or touch-sensitive input panels, have recently also found their way into the interior of motor vehicles. In such an application, they can be used for operator control of a wide variety of functions of the motor vehicle or of an appliance installed in the motor vehicle, such as a navigation appliance, for example.
In order to allow appropriate operator control, these operator control panels require a relatively large surface area. However, a large surface area may be regarded as troublesome, particularly in high-end vehicles with correspondingly high-end interior fittings, because the touchpads in some cases require very large areas of the interior trim cut out. This interior trim removal greatly interferes with the aesthetics of the interior of the motor vehicle.
SUMMARY
Therefore, the following description relates to an apparatus for the operator control of a function of a motor vehicle or of an appliance installed in a motor vehicle, while providing the least possible disruption to the interior design aesthetic of the motor vehicle.
In accordance with one aspect of the present disclosure, an operator control apparatus for operator control of at least one function of a motor vehicle having a surface formed from a material includes a touch-sensitive input panel comprising a transparent material, wherein the touch-sensitive input panel is arranged above the surface of the motor vehicle such that the material forming the surface of the motor vehicle can be perceived through the touch-sensitive input panel.
Because the touch-sensitive input panel is produced from a transparent material, it can be fitted on any desired base support in the interior of the motor vehicle without disrupting the interior design and without requiring the provision of a cutout or the like on the base support. This results in significantly improved design freedom, in comparison with known solutions, for the area in which the touch-sensitive input panel is arranged. The material and the surface of the base support may be perceived through the touch-sensitive input panel, which is advantageous, particularly when the surface of the base support is made from a high-quality material, such as wood, metal, or leather, for example. Accordingly, operators of the motor vehicle may derive a particularly high-quality impression from the design of the interior of the motor vehicle.
In order to achieve a floating impression for the touch-sensitive input panel, the touch-sensitive input panel may be arranged at a distance from a base support.
This floating impression may also be reinforced when the distance between the touch-sensitive input panel and the base support is greater than or equal to approximately 3 millimeters.

FIG. 1 illustrates an embodiment of the apparatus;
FIG. 2 illustrates an embodiment of the apparatus;
FIG. 3 illustrates an embodiment of the apparatus;
FIG. 4 illustrates an embodiment of the apparatus according to the invention, and
FIG. 5 illustrates a view of an embodiment of the apparatus in the direction of the arrow V from FIG. 1.



DETAILED DESCRIPTION
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.
FIG. 1 illustrates a portion of a center console 1 in an interior of a motor vehicle, the entirety of which is not shown. Adjacent to the center console 1 is a vehicle seat 2, which is likewise not shown completely. Arranged above the center console 1 in a known configuration is an arm support or armrest 3 which may be foldable.
Next to a gear selector lever 4, the center console 1 furthermore holds an apparatus 5 for the operator control of at least one function of the motor vehicle and/or of at least one appliance installed in the motor vehicle. The apparatus 5 may be used to operate a wide variety of functions of the motor vehicle, such as the adjustment of shock absorbers, or particular engine maps, for example, and also different functions of various appliances installed in the motor vehicle, such as a navigation appliance, an air conditioning system, or a cruise control system, for example.
To this end, the apparatus 5 in the present case has, among other things, a touch-sensitive input panel 6 which may be produced from a transparent material, so that it is possible to selectively perceive functions on the input panel and the material and surface of the center console 1 through the touch-sensitive input panel 6. This is advantageous, particularly when the surface of the center console 1 is made from a high-quality material, such as wood, metal, or leather, for example. Accordingly, operators of the motor vehicle may derive a particularly high-quality impression inform the design of the interior of the motor vehicle. By way of example, a touch-sensitive input panel 6 of this kind may allow the use of character recognition to achieve particularly convenient operator control of the motor vehicle or of the appliance installed therein.
In addition to the touch-sensitive input panel 6, the apparatus 5 in the present case may also include a rotatable ring 7 which surrounds the touch-sensitive input panel 6. The rotatable ring 7 may be an input device for the operator control of at least one function of the motor vehicle and/or of the appliance installed in the motor vehicle. The rotatable ring 7 can thus be used to extend the functionality of the touch-sensitive input panel 6. In addition, the apparatus 5 in the exemplary embodiment shown also has two switching elements 9, which may be provided in the form of pressure switches, which are arranged on a frame 8 encompassing the touch-sensitive input panel 6 and the rotatable ring 7. The switching elements 9 may likewise perform particular operator control functions for the motor vehicle and/or the appliance installed therein.
Whereas the apparatus 5 has the frame 8 fitted completely above the center console 1 in the embodiment in FIG. 1, it projects beyond the center console in the embodiment shown in FIG. 2, so that other operator control opportunities and other opportunities for supporting the arm of the operator are obtained.
FIG. 3 illustrates an embodiment of the apparatus 5 in which the frame 8, with the touch-sensitive input panel 6, is mounted on at least one rail, such as two rails 10 running parallel to one another as shown, for example. In this embodiment, the frame 8 with the touch-sensitive input panel 6, the rotatable ring 7, and the switching elements 9 may be displaced. As a further example, the rails 10 may also form a curved path.
The embodiment in FIG. 4 illustrates the apparatus 5 with the frame 8 and the touch-sensitive input panel 6 held therein, the rotatable ring 7, and the switching elements 9 fitted on the armrest 3 instead of on the center console 1. Although not shown, in this embodiment, the frame 8 may also be displaceable on rails 10 fitted on the armrest 3.
FIG. 5 illustrates the touch-sensitive input panel 6 arranged at a distance from a base support, such as from the center console 1 or the armrest 3, for example. The distance between the touch-sensitive input panel 6 and the base support may be greater than or equal to approximately 3 millimeters in order to achieve a floating impression. Alternatively, however, the touch-sensitive input panel 6 may be fitted directly on the surface of the center console 1 or the armrest 3.
In all of the embodiments shown, the rotatable ring 7 surrounding the touch-sensitive input panel 6 and/or the switching elements 9 may be optionally excluded. Also, frame 8 may be optionally excluded if the touch-sensitive input panel 6 were fitted directly on the respective base support, such as the center console 1 or the armrest 3, for example.
The invention has been described in detail with particular reference to preferred embodiments thereof and examples, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention covered by the claims which may include the phrase “at least one of A, B, and C” as an alternative expression that means one or more of A, B, and C may be used, contrary to the holding in Superguide v. DIRECTV, 69 USPQ2d 1865 (Fed. Cir. 2004).
