[0032] FIG. 1 shows a schematic cross sectional illustration of an operating device 100 for selecting at least one gear setting of a vehicle according to an exemplary embodiment. The operating device 100 is configured to at least set the gear setting of the vehicle. The operating device 100 has at least one sensor 105 and one deformable surface 110 for this. According to this exemplary embodiment, the operating device 100 has four sensors 105, two of which sensors 105 can be seen in the cross section shown herein. The deformable surface 110 is configured to form at least one haptic operating element 120 with the sensors 105 that has at least one touch-sensitive region when it is in the deformed state 115. The surface 110 is shown in the deformed state 115 in FIG. 1, in which the haptic operating element 120 exhibits a recess according to this exemplary embodiment.

[0033] According to various exemplary embodiments, the sensor(s) 105 can be integrated in the surface 110 or located on the surface 110. The surface 110 can be formed as a deformable layer, e.g. a film or suchlike.

[0034] According to one exemplary embodiment, each of the sensors 105 has a dedicated touch-sensitive region, or a touch-sensitive region is formed by each sensor 105. The haptic operating element 120 is configured to output a selection signal indicating the actuation of the operating device 100 in response to touching the haptic operating element 120 in or on the touch-sensitive region or one of the touch-sensitive regions. The selection signal can be an electric signal that is received by a transmission control device and used for setting a gear setting to which one of the touch-sensitive regions that has been touched is dedicated.

[0035] The operating device 100 has at least one actuator 130, four actuators 130 according to this exemplary embodiment, two of which actuators 130 are visible in the cross section. The actuators are configured to convert the surface 110 to the deformed state 115. According to this exemplary embodiment, the actuators 130 are low-voltage actuators with a high level of expansion. The surface 110 is made of a magnetorheological material according to this exemplary embodiment. According to this exemplary embodiment, each of the actuators 130 can be actuated separately, or the actuators 130 can be actuated collectively, in order to deform the surface 110. For this, the actuators 130 are configured to each receive an electric actuation signal according to an exemplary embodiment.

[0036] The present approach describes an operating device 100 that generates at least one haptic operating element 120 or numerous haptic operating elements 120 for selecting a gear setting in closed surfaces 110. The operating device 100 can accordingly also be referred to as a device for generating haptic operating elements 120 in closed surfaces for selecting gear settings of a vehicle, or as a 3D-tronic. The operating device 100 presented herein is based on the fundamental principle that the surface 110 is deformed three dimensionally, thus generating the operating element 120 in the form of a finger track according to this exemplary embodiment, on which a user can orient in a tactile manner using the receptors of the human hand, in order to thus enable a guided, blind operation of the operating element 120. The haptic operating element 120 depicted herein has a touch-sensitive region, which either forms a display region on the whole, or comprises individual display sections, as is the case in the following exemplary embodiments shown in FIGS. 3, 6, 9 and 12. The region also contains the respective circuit diagram for the transmission settings, by means of which the driver can select the possible gear settings, also referred to as drive positions, by means of finger movement. The haptic operating element 120 according to this exemplary embodiment also contains recesses and/or, as shown in FIGS. 7 to 12, raised sections that form a haptic guide for the finger, providing the user, who can also be referred to as the driver or operator, with an intuitive and non-distracting operation by means of tactile perception.

[0037] The haptic operating element 120 can be formed using various technologies, and according to this exemplary embodiment, the surface 110 contains magnetorheological elements, wherein this material becomes deformed in a magnetic field, and returns to its initial shape after the magnetic field is switched off.

[0038] A quality of the surface 110 can be obtained using various materials, patterns and structures, which enable a three dimensional deformation, e.g. plastics with elastic properties such as elastomers, and/or wood, and/or metals, and/or rock, and/or substances such as synthetic substances, and/or leather. The structure of the surface 110 can be polygonal and/or hexagonal.

[0039] The haptic operating elements 120 can be formed or received in different surfaces 110 in the vehicle, e.g. armrests, hand rests, a central console, a steering wheel, and/or a dashboard of the vehicle. A setting of the haptic operating element 120, i.e. the converting of the surface 110 to the deformed state 115, can be initiated and deactivated with different processes, i.e. when the vehicle is started, or by means of a proximity sensor system.

According to an exemplary embodiment, the sensors of the operating device 100 are deactivated in this state. According to one exemplary embodiment, the sensors are activated in response to an activation of the actuators 130 for converting the surface 110 to the deformed state, and deactivated in response to a renewed activation of the actuators 130 or a deactivation of the actuators 130 for converting the surface 110 to the deformed state 200. Alternatively, the sensors can be active independently of the state of the surface 110, and thus independently of a state of the actuators 130.

According to an alternative exemplary embodiment, the entire touch-sensitive region forms the display section 305. The touch-sensitive display sections 305 of the operating elements 120 are equipped with haptic feedback by means of various technologies, such as an electrostatic film or a solution based on piezo actuators, according to this exemplary embodiment, in order to make targeted individual regions of the operating surface, such as the shifting surface and the actuation field perceivable.
