Description

  • The invention relates to an operating device for a motor vehicle, comprising a sensor device, and a user interface covering the sensor device, wherein the sensor device is designed to detect an actuating force applied to the operating surface, and wherein the user interface has a first rigidity in a first operating region and at least a second operating region has a second stiffness greater than the first stiffness. The invention also relates to a motor vehicle.
  • Operating devices for motor vehicles are already known from the prior art. By means of an operating device, a person, for example a driver or another occupant of the motor vehicle, can select, trigger or control functions of the motor vehicle. The EP 2 450 207 A2 shows, for example, a arranged on a bumper of a motor vehicle sensor which is contactlessly actuated, for example, to open a tailgate of the motor vehicle.
  • It may also be that the operating device is designed pressure-sensitive and thus by means of an actuating force, which applies the person, for example with her finger on a user interface of the operating device and which is detected for example by a pressure sensor of the operating device, can be actuated. It is usually a force detection or a touch detection on user interfaces, which are flat or slightly curved, no problem. However, as soon as the user interface has structures, for example edges or other geometrically shaped elements, operating forces in these areas on the user interface can no longer be easily recognized and evaluated. This results in restrictions with regard to the arrangement of the operating devices in the motor vehicle, since proper operation of the operating device on edges or structures within the motor vehicle is not possible.
  • It is an object of the present invention to realize a reliable operating device, which can be positioned particularly flexibly in a motor vehicle.
  • This object is achieved by an operating device and by a motor vehicle having the features according to the independent claims. Advantageous embodiments of the invention are the subject of the dependent claims, the description and the figures.
  • An operating device according to the invention for a motor vehicle comprises a sensor device and a user interface covering the sensor device. In this case, the sensor device is designed to detect an applied to the user interface operating force. The user interface has a first operating area with a first rigidity and at least one second operating area with a second rigidity that is greater than the first rigidity. In addition, the sensor device comprises a first sensor region, which has a first sensitivity and is assigned to the first operating region, and at least one second sensor region, which has a second sensitivity and is assigned to the at least one second operating region, wherein the second sensitivity increases with respect to the first sensitivity is. In other words, the second sensitivity is greater than the first sensitivity.
  • By means of the pressure-sensitive operating device, for example, functions of the motor vehicle can be selected and / or triggered by a user applying the actuating force, for example with his finger, to the operating surface or touching the operating surface. This actuating force or this contact can be detected by the sensor device.
  • The user interface comprises at least two operating areas, each of which has different rigidity. The stiffness as a mechanical parameter describes a resistance of the user interface against a deformation of the user interface by the applied actuating force. In the first operating area, which has the lower rigidity, the operating surface can be deformed more easily by the applied actuating force than the operating surface in the at least one second operating area with the same actuating force. The rigidity depends in particular on the elastic properties of the user interface and on the geometry of the user interface. Thus, to form the second rigidity, at least one edge can preferably be formed within the second operating region. The increased second rigidity results from the bending moment, which is applied to the formation of the at least one edge on the user interface. The different stiffnesses have the consequence that the user interface is deformed differently within the respective operating areas with the same applied operating force. In a pressure sensor according to the prior art, which detects the actuation force on the user interface of the operating device, this operating range-dependent deformability would result in different, operating range-dependent sensor output signals of the pressure sensor, which may for example lead to a faulty triggering of a function or to a non-triggering of a function.
  • However, in order to compensate for these different, user-area-dependent deformability, the pressure-sensitive sensor device according to the invention comprises at least two sensor regions, the first sensor region having a lower sensitivity than the at least one second sensor region. In this case, the first sensor area is covered by the first operating area, and the at least one second sensor area is covered by the at least one second operating area, so that an actuating force or an actuating pressure on the first operating area is detected by the first sensor area and an actuating force or an actuating pressure on the second operating area is detected by the second sensor area. In other words, this means that the operating area with the higher rigidity is assigned to the sensor area with the higher sensitivity and the operating area with the lower rigidity is assigned to the sensor area with the lower sensitivity, whereby the different sensitivities of the user area in the sensor area are due to the different sensitivities of the sensor areas the operating areas are compensated.
  • In this case, the respective sensitivity is particularly preferably adjusted such that a sensor output signal of the sensor device is independent of an operating location on the user interface with the same applied actuating force. In other words, this means that the sensitivity of the first sensor area is set so that applying the actuating force to an operating location in the first operating area results in the same sensor output signal of the entire sensor device as applying the same amount of actuating force to an operating location in the second operating area.
  • Thus, advantageously, an actuating force can be detected and evaluated reliably on user interfaces which have geometric shapes and edges. The operating device can thus be positioned particularly flexibly in the motor vehicle, in particular in areas of the motor vehicle which have geometric shapes and edges.
  • According to one embodiment of the invention, the sensor device has two electrically conductive films and an elastically deformable carrier, which is arranged between the electrically conductive films. The electrically conductive films and the elastically deformable carrier thus approximately form a plate capacitor, in which the electrically conductive films form the electrodes of the plate capacitor and the electrically non-conductive, elastically deformable carrier forms the dielectric between the electrodes. The sensor output signal of the sensor device can be, for example, a total capacitance of the plate capacitor, which is proportional to an area of the electrically conductive films and to a permittivity of the elastically deformable carrier, as well as indirectly proportional to a distance between the films, which is formed by a thickness of the dielectric is is. In particular, an actuating force is evaluated capacitively, that is, a change in the total capacitance of the plate capacitor and thus of the output sensor signal is detected.
  • In particular, the operating device has a layered structure which comprises the user interface, a first of the conductive films as an upper electrode, the elastically deformable support, and a second of the conductive films as a lower electrode which is stationary with respect to the upper electrode. The user interface is preferably designed as a flexible film which can be impressed locally, for example, at the position of the applied actuating force by the applied actuating force. By pressing the user interface and due to the fixed arrangement of the lower electrode of the elastically deformable support is also pressed, whereby the first film is moved toward the stationary second film. As a result, a distance of the films to each other and thus the total capacity is changed. By using films as electrodes, the operating device is designed to save space.
  • In one development of the invention, the electrically conductive foils for setting the respective sensitivity in the at least one second operating area have a larger surface area than in the first operating area. The electrically conductive foils and the elastically deformable carrier thus form in the first operating region a first plate capacitor having a first capacitance and in the at least one second operating region a second plate capacitor having a second capacitance. The first and the second plate capacitor are thus connected in parallel, resulting in the total capacity of the sum of the first and the second capacity. Because the electrically conductive foils in the at least one second operating region have a larger area than in the first operating region, the second plate capacitor also has a larger second capacitance than the first plate capacitor.
  • Due to the greater rigidity of the user interface in the at least one second operating area, an actuating force on the operating surface in the at least one second operating area leads to a lower deformation of the user interface, in particular to a lower impression of the user interface than the same actuating force on the user interface in the first operating area with the lower rigidity. As a result, the distance between the foils to each other despite the same operating force in the second operating area less than the distance between the foils to each other in the first operating area. In order to compensate for this operating-range-dependent change in distance, the surface area of the electrically conductive foils in the second operating area is larger than the first operating area. Thus, the first capacity at an actuation pressure on the less rigid user interface has the same value as the second capacitance at the same actuation pressure on the stiffer surface. The first and the second capacity thus provide the same contribution to the total capacity at the same operating pressure. Thus, a sensitivity can be adjusted in a particularly simple manner by the surface areas of the electrically conductive films in the respective operating areas.
  • Alternatively or additionally, the elastically deformable carrier has a higher permittivity for setting the respective sensitivity in the at least one second sensor region than in the first sensor region. By increasing the permittivity or the dielectric constant of the elastically deformable carrier in the at least one second sensor region, the same result can be achieved as by increasing the surface area of the electrically conductive foils in the at least one second operating region since, as already described, the capacitance is direct is proportional to the surface area of the electrodes as well as the permittivity of the dielectric.
  • Alternatively or additionally, the elastically deformable carrier for setting the respective sensitivity in the at least one second sensor region has a smaller thickness than in the first sensor region, so that a distance of the electrically conductive films from each other in the second sensor region is smaller than in the first sensor region. To increase the second capacitance in the second sensor region, alternatively or additionally to the enlargement of the surface area of the films and to increase the permittivity of the elastically deformable carrier, the distance between the films relative to one another in the second operating region can also be reduced. To vary the spacing of the films, the thickness of the elastic support can be adapted locally in a particularly simple manner.
  • According to a development of the invention, for adjusting the respective sensitivity, the elastically deformable carrier in the second sensor region has greater elasticity than in the first sensor region. In other words, this means that the elastically deformable carrier in the first sensor region has a greater modulus of elasticity than in the second sensor region. This has the consequence that the elastically deformable carrier in the first operating range of its deformation by a force applied directly to the electrically conductive foil actuating force opposes more resistance than the elastically deformable carrier in the second operating area. Thus, the distance of the electrically conductive foils to one another in the second operating region would be reduced more by an actuating force applied directly to the electrically conductive foil, than the distance of the electrically conductive foils in the first operating region by an actuating force which is directly equal to one of the electrically conductive foil. In combination with the user interface, the distance between the foils to one another in the second operating area is changed by an actuating force applied to the stiffer operating surface to the same extent as the distance between the foils to each other in the first operating area by an equal operating force applied to the less rigid user surface , Thus, the increased rigidity of the first operating area can be compensated for particularly easily. In particular, the user receives the same haptic feedback with the same applied actuating force at each operating point on the user interface. This means that the user does not directly sense the operating-range-dependent stiffness, since this is compensated by the wearer's area-dependent and thus operating-range-dependent elasticity of the wearer.

  • 3 shows an embodiment of an operating device according to the invention 24 , Can also be used for selecting and / or triggering functions of the motor vehicle. The operating device 24 is shown here in a side view or a sectional view. Areas of the operating device 24 in the xy-plane are thus not shown here The operating device 24 includes a user interface 26 which has a first operating area 28 and a second operating area 30 having. The first operating area 28 has a first stiffness and the second operating area 30 a second stiffness greater than the first stiffness. The second, greater stiffness in the second operating area 30 results here from edges 32 , which by an applied bending moment in the second operating area 30 are formed. The user interface 26 in the second operating area 44 So is by applying an actuating force by the finger 22 less deformed than the user interface 26 in the first operating area 42 by applying the same operating force.
  • The operating device 24 also includes a sensor device 34 which is a first electrically conductive foil 36 , a second electrically conductive foil 38 and an elastically deformable carrier 40 having. The operating device 10 So has a layered structure in the negative z-direction, which is the user interface 26 , the first electrically conductive foil 36 , the elastically deformable, electrically non-conductive support 40 and the second electrically conductive film 38 which are stationary with respect to the first film 36 is included. The sensor device 34 is thus formed as a plate capacitor having a total capacitance C ges . The total capacitance C ges is directly proportional to an area A of the electrically conductive foils 36 and 38 and to a permittivity ε of the elastically deformable carrier 40 , as well as indirectly proportional to a distance of the electrically conductive films 36 and 38 to each other, which by a thickness d of the elastically deformable carrier 40 is formed. By applying an actuating force by the finger 22 becomes the user interface 26 pressed at the respective operating point and the elastically deformable carrier 40 is deformed, in particular also pressed. This reduces the thickness d of the electrically deformable carrier 40 and thereby the distance of the films 36 and 38 to each other. This results in a change in the total capacitance C ges and thus in a change in the sensor output signal.
  • The sensor device 34 also has a first sensor area 42 with a first sensitivity and a second sensor area 44 with a second sensitivity on. In the first sensor area 42 thus form the electrically conductive films 36 and 38 a first plate capacitor having a first capacitance C1. The first capacitance C1 is proportional to an area A1 of the electrically conductive foils 36 and 38 in the first operating area 28 and to a first permittivity ε1 of the elastically deformable carrier 40 in the first sensor area 42 , as well as indirectly proportional to a first distance of the electrically conductive films 36 and 38 to each other, which by a first thickness d1 of the elastically deformable carrier 40 in the first sensor area 42 is formed. In the second sensor area 44 form the electrically conductive films 36 and 38 a second plate capacitor with a second capacitance C2. The second capacitance C2 is proportional to a surface area A2 of the electrically conductive foils 36 and 38 in the second operating area 30 and to a second permittivity ε2 of the elastically deformable carrier 40 in the second sensor area 44 , as well as indirectly proportional to a second distance of the electrically conductive films 36 and 38 to each other, which by a second thickness d2 of the elastically deformable carrier 40 in the second sensor area 42 is formed. The total capacitance C ges results from the sum of the first capacitance C1 and the second capacitance C2.

As a result, the first sensor area 42 but has a lower sensitivity than the second sensor area 44 the total capacitance C tot in the same degree will change, independently of the operator control. Thus, the operating force can be detected quantitatively and reliably.
  • In 4 is an embodiment of a sensor device 34 an operating device 24 shown in a plan view in the xy plane. The sensor device 34 here includes four first electrically conductive films 36 , Due to the top view of the sensor device 34 Here are only the first electrically conductive films 36 as well as in the drawing plane below, so located in the negative z-direction, elastically deformable carrier 40 shown. The second electrically conductive films 38 are located in the negative z-direction under the elastically deformable carrier 40 and are therefore not recognizable here. The first electrodes 16 , the non-conductive spacer 20 and the second electrodes, not shown here 18 each form a plate capacitor, each of the plate capacitors having the total capacitance C ges .
  • The electrically conductive first films 36 have here a trapezoidal shape, whereby the electrically conductive films 36 in the first sensor area 42 a smaller area A1 than in the second sensor area 44 exhibit. The sensor area 44 in which the electrically conductive films 36 have the larger area A2 is at the edge 36 of the second operating area 30 arranged. The increased second sensitivity is in This embodiment thus adjusted by the increased surface area A2.
  • By the embodiment, an operating device or a control panel with capacitive touch evaluation and / or force evaluation of geometrically shaped elements, such as edges, shown. Thus, the sensor area, which is specially adapted to the surface geometry, for example to a stable and rigid area, counteract a deviation of the sensor output signal and thus reliably detect an actuating force.
