Definitions

  • the invention relates to a motor vehicle operating device for an interior of a motor vehicle.
  • Motor vehicle operating devices are known from the prior art with which a vehicle occupant can control functions of a motor vehicle.
  • a vehicle occupant can control functions of a motor vehicle.
  • This is, for example, a light bar or a light island, on which the vehicle lighting can be adjusted.
  • a light bar or light island may include further functions that the vehicle occupant can control via the corresponding motor vehicle operating device, for example front or rear window heating, play heater or rear fog light.
  • motor vehicle operating devices which comprise a user interface, on which a plurality of switching symbols are shown.
  • the symbols are printed on keys that are mechanically operated to activate or deactivate the assigned function.
  • the buttons are assigned pressure sensors, which recognize the mechanical operation accordingly.
  • capacitive motor vehicle operating devices which comprise capacitively designed operating elements, which likewise include switching symbols.
  • capacitively designed controls an approach and a touch of the user interface can be detected in a simple manner. A mechanical operation is not required.
  • the capacitively trained controls the same functionality as the pressure sensors are achieved, so activate or deactivate a function.
  • the object of the invention is to provide a motor vehicle operating device which is inexpensive and easy to manufacture, having an increased functionality.
  • a motor vehicle operating device for an interior of a motor vehicle, with a user interface on which a plurality of symbols are shown, each associated with a touch sensor, wherein the touch sensors are each configured to detect an approach and / or a touch of the user interface wherein the motor vehicle operating device further comprises a plurality of pressure sensors associated with the switching symbols, wherein the number of pressure sensors is less than the number of touch sensors.
  • the basic idea of the invention is that the motor vehicle operating device has increased functionality by using different sensors which are provided for detecting different operations of the motor vehicle operating device. The different sensors are the touch sensors and the pressure sensors.
  • An approximation and / or a touch of the user interface can be detected via the touch sensors, whereas the additional pressure sensors detect a pressure exerted on the user interface, ie a mechanical actuation which requires a force. Since the number of pressure sensors is less than the number of switching symbols, the cost of producing the motor vehicle operating device is also lower than in the known from the prior art motor vehicle operating devices comprising a plurality of pressure sensors, each associated with a corresponding key.
  • the pressure sensors can be arranged in such a way that, in a triangulation method, in particular involving the geometry of the user interface, they determine the location on the operating surface to which the actuation or operating force is applied. Accordingly, those of the evaluated several signals sensor signals to (at least roughly) close to the location on the user interface, where the vehicle occupant has pressed on the user interface.
  • the touch sensors and / or the pressure sensors are capacitively and / or piezoelectrically designed.
  • the touch sensors can be designed as self-capacitive touch sensors, so that they easily detect an approach to the user interface.
  • the pressure sensors may be capacitively formed, wherein, for example, two capacitor plates are provided whose distance from each other is changed, if a pressure is exerted on the user interface. This is detected accordingly via the pressure sensors or the electric field changing as a result, in order to conclude a corresponding actuation.
  • the pressure sensors may be formed by piezoelectric sensors that convert an applied pressure (actuation) into an electrical signal, which can be evaluated.
  • the motor vehicle operating device comprises an evaluation unit that is coupled to the touch sensors and the pressure sensors in order to evaluate the acquired data.
  • the respective sensors therefore transmit the acquired data to the evaluation unit, that is to say the touch or approach signal and the actuation signals.
  • the evaluation unit evaluates the different signals in order to conclude a specific approach / touch or actuation of the motor vehicle operating device, in particular the user interface.
  • the signals of the different sensors can be linked with one another in order, for example, to detect an actuation of a specific switching symbol, even if a pressure sensor is not assigned directly to this switching symbol.
  • the touch sensors form a touch sensor, which is designed to detect and locate an approach and / or a touch of the user interface. This is done in a simple manner in that the respective switching symbols is associated with exactly one touch sensor, so that the approach or touch of a Switch symbol is detected via the associated capacitive touch sensor of the touch sensor. The corresponding signal is forwarded to the evaluation unit, which activates the function associated with the approach or touch.
  • the touch sensor system can also be designed such that it already recognizes an approach to the entire user interface of the motor vehicle operating device, that is not to a specific switching symbol, wherein due to the approach to the entire user interface, a function is activated, for example, a search lighting of the motor vehicle operating device is turned to to backlight the individual symbols. The search light therefore makes it easier to find the buttons on the user interface so that they can be operated accordingly.
  • the pressure sensors may form an actuation sensor configured to detect a pressure on the user interface. As soon as the vehicle occupant presses on the user interface, this is detected by the plurality of pressure sensors, that is to say the actuation sensor system. As already explained, the pressure sensors can estimate, based on a triangulation method, at which position the vehicle occupant has actuated the user interface. The more pressure sensors available, the more accurate the estimate. In particular, the user interface is considered as a boundary condition.
  • the touch sensor system and the actuation sensor system are designed such that together they detect an actuation of one of the several circuit symbols.
  • the touch sensor detects, for example, to which switching symbol the corresponding operating object has previously approached, so that only the plausibility of the pressure sensors of the actuation sensor, whether actually the corresponding switching symbol has also been actuated by a pressure on the switching symbol has been exercised. As a result, an accidental operation can be effectively prevented by unintentional contact.
  • the actuation sensor system can serve to check the plausibility of the touch sensor system if the touch sensor system reacts to a touch.
  • the motor vehicle operating device may be configured to detect an approach to the entire user interface, an approach to one of the plurality of switching symbols, a touch of one of the plurality of switching symbols and / or a pressing of one of the plurality of switching symbols, in particular where different functions are assigned to the detected states. Due to the approach to the entire user interface, a search illumination can be switched on, so that the switching symbols displayed on the user interface are backlit, making it easier for the vehicle occupant to find the corresponding switching symbol to be switched.
  • the assigned function can already be activated so that it does not have to touch the corresponding switching symbol.
  • the vehicle occupant must touch the corresponding switching symbol in order to carry out the function.
  • the contact of the switching symbol activates a further function assigned to the switching symbol.
  • a further function which is linked to the specific switching symbol, can be activated by pressing the switching symbol, that is to say applying a mechanical pressure to the corresponding switching symbol.
  • the motor vehicle operating device may comprise a maximum of n pressure sensors at n + 2 touch sensors, where n is an integer> 1. This makes it possible for an extremely high functionality of the motor vehicle operating device to be created via n pressure sensors and n + 2 touch sensors. Since each switching symbol is associated with a touch sensor, there are n + 2 switching symbols in each of which a mechanical actuation can be detected, with fewer pressure sensors being provided as switching symbols. For example, six switching symbols on the user interface, six touch sensors and four pressure sensors are provided.
  • the motor vehicle operating device comprises a printed circuit board, the touch sensors being arranged on a first printed circuit board surface of the printed circuit board assigned to the user interface are.
  • the touch sensors may be formed by electrodes disposed in the respective areas of the circuit board associated with the switching symbols.
  • the user interface is at least partially electrically conductive, so that it forms the contact sensors together with the electrodes on the circuit board.
  • the user interface may be provided on a panel which is a two-component injection molded part.
  • the pressure sensors may be arranged on a second circuit board surface opposite the first circuit board surface.
  • the first circuit board surface may be referred to as the front side, whereas the second circuit board surface may be referred to as the back side.
  • the second printed circuit board surface ie the rear side, can be assigned to a basic module of the motor vehicle operating device, on which the pressure sensors are supported, in order to convert a correspondingly applied pressure into an electrical signal.
  • the distance between the capacitor plates of the capacitively formed pressure sensors changes, if a pressure is exerted, since the capacitor plates assigned to the basic module can not be displaced further, so that their distance from the operating surface decreases.
  • a pressure is generated in piezoelectric pressure sensors, which is correspondingly converted into an electrical signal.
  • FIG. 1 shows an exploded view of a motor vehicle operating device according to the invention
  • FIG. 2 shows the front side of a printed circuit board of the motor vehicle operating device according to FIG. 1, and FIG.
  • FIG. 3 shows the rear side of the printed circuit board of the motor vehicle operating device according to FIG. 1.
  • FIG. 1 shows a motor vehicle operating device 10 which, in the embodiment shown, is designed as a light island 12.
  • the motor vehicle operating device 10 comprises a basic module 14, which comprises a plug chamber 15 into which a plug (not shown here) for electrical connection of the motor vehicle operating device 10 can be inserted.
  • a circuit board 16 is also received, the contact pins 18 which extend in the assembled state in the connector chamber 15 to be contacted by the plug.
  • the printed circuit board 16 has a first printed circuit board surface 20 shown in FIG. 1, which may also be referred to as the front side (FIG. 2).
  • the printed circuit board 16 has a second printed circuit board surface 22, which is opposite to the first printed circuit board surface 20, and which may also be referred to as the rear side (FIG. 3). Via the second printed circuit board surface 22, the printed circuit board 16 is supported on the base module 14, as will be explained below.
  • the motor vehicle operating device comprises a diaphragm 24, which forms an operating surface 26, on which a plurality of switching symbols 28 are shown, which functions of the motor vehicle are assigned, which can be activated or deactivated via the switching symbols 28, as will be explained below.
  • the switching symbols 28 are partially transparent, so that they can be backlit by a search illumination 32.
  • the search illumination 32 also includes light guides 34, which are also shown in FIG.
  • the light guides 34 are each delimited laterally by Lichtabschottungen 36. This ensures that the functional light sources associated with the light exit surfaces 30, which are not shown in detail on the printed circuit board 16, are not illuminated by the light emanating from the light guides 34.
  • the switching symbols 28 are associated with both touch sensors 38 and pressure sensors 40.
  • the touch sensors 38 are arranged on the first printed circuit board surface 20, which in the assembled state of the motor vehicle operating device 10 is assigned to the user interface 26.
  • the touch sensors 38 are designed as capacitive sensors, in particular self-capacitive sensors, so that they already detect an approach to a corresponding switching symbol 28. Accordingly, these are electrode areas provided on the first board surface 20.
  • the touch sensors 38 may be formed as capacitive sensors that together with the user interface 26 form a capacitor whose electric field is changed, as long as the partially electrically conductive user interface 26 is touched.
  • the pressure sensors 40 are arranged on the second printed circuit board surface 22, via which the printed circuit board 16 is supported on the base module 14.
  • the basic module 14 has correspondingly designed support surfaces 42 on which the pressure sensors 40 rest accordingly when the motor vehicle operating device 10 is in the assembled state.
  • the pressure sensors 40 may be designed as capacitive sensors, for example by two opposing capacitor plates, so that they convert a change in distance into a corresponding electrical signal.
  • the pressure sensors 40 are formed as piezoelectric sensors, so that they convert an applied pressure into an electrical signal.
  • the plurality of pressure sensors 40 may also be designed mixed, that is, partly as capacitive sensors and the other part as piezoelectric sensors.
  • the printed circuit board 16 may comprise an evaluation unit 44 (see FIG. 3) which is coupled to the touch sensors 38 and the pressure sensors 40 in order to detect different operating or operating scenarios.
  • the touch sensors 38 together form a touch sensor 46, via which an approach to the user interface 26 or a specific switching symbol 28 and / or a touch of the corresponding switching symbol 28 can be detected and located. This is because each switch symbol 28 is associated with a touch sensor 38.
  • the touch sensor 46 may be formed by a capacitive foil having a matrix structure such that the individual touch sensors 38 are formed.
