Description

[0001] The invention relates to an operating device for a motor vehicle, specifically an operating device with an operating part that can be displaced from a rest position toward at least one end stop for operation and that automatically returns to its rest position. Furthermore, the invention relates to a motor vehicle with such an operating device.

[0002] It is known that operating devices with a monostable control element are installed in the interior of a motor vehicle. A monostable control element can assume multiple positions, but with a monostable control element, only one position, namely a single rest position, is stable. Starting from the unstable positions, the control element automatically returns to its stable rest position.

[0003] To provide a particularly high-quality control device, the control device must exhibit a high-quality haptic response in the rest position. Thus, the control device should neither wobble in the rest position when not actuated, nor jam or catch when moved from the rest position. To date, it has been difficult to provide a control device with such a haptic response in the rest position.

[0004] There is a need for an operating device of a motor vehicle with an operating part which, starting from a position displaced from a rest position, automatically returns to its rest position, wherein in the rest position the operating part should neither wobble in the unactuated state nor jam or catch when displaced from the rest position.

[0005] DE 10 2014 002 030 A1 discloses a haptic-generating device, namely an electrical switch.

[0006] DE 10 2008 060 256 A1 discloses a control element with adjustable haptics. The haptics are provided by permanent magnets.

[0007] DE 10 2017 120 076 B3 discloses a switching device with magnetic detent. The switching device has an actuating element coupled to a haptic device.

[0008] DE 10 2012 222 237 A1 discloses a control element with magnetic haptics. The control element comprises an operating lever and a driver lever, with a permanent magnet attached to the driver lever. Haptic feedback is generated when the driver lever is pivoted.

[0009] DE 10 2007 058 001 A1 discloses a control device for a manual transmission with a joystick. At least one permanent magnet is attached to an element that is attached to the joystick and can be moved by the joystick. Along the movement path of the joystick, additional permanent magnets are arranged on a support. These permanent magnets have a polarity opposite to that of the permanent magnet moved by the joystick.

[0010] DE 10 2014 103 988 A1 discloses an operating device of a motor vehicle with an operating part which automatically returns to its rest position.

[0011] US 2016 / 0 230 878 A1 discloses a further operating device, wherein a plunger is guided in an operating part of the operating device, which plunger is subjected to a spring force via a spring element arranged in the operating part and which is pressed against a guide via the spring force of the spring element.

[0012] DE 10 2006 002 634 A1 and discloses further prior art.

[0013] The object of the invention is to provide a novel operating device of a motor vehicle with an operating part, wherein the operating part neither wobbles in the rest position nor jams or catches when moved from the rest position.

[0014] Furthermore, a motor vehicle with such an operating device is to be provided.

[0015] This object is achieved on the one hand by an operating device of a motor vehicle according to patent claim 1 and on the other hand by a motor vehicle according to patent claim 11.

[0016] The operating device according to the invention comprises an operating part which, for operation, can be pivoted from a rest position toward at least one end stop and which automatically returns to the rest position. A plunger is guided in the operating part, which is subjected to a spring force via a spring element arranged in the operating part.

[0017] The operating device according to the invention has a guide which defines the rest position of the operating part, wherein the plunger can be displaced along the guide when the operating part is pivoted and is pressed against the guide by the spring element, and wherein, depending on the pivoting movement of the operating part, the plunger can be displaced further into the operating part against the spring force of the spring element or further out of the operating part by the spring force of the spring element.

[0018] The operating device according to the invention has at least one first permanent magnet arranged in the region of the rest position and fixed relative to the guide and at least one ferromagnet or second permanent magnet fastened to the operating part.

[0019] The at least one first permanent magnet interacts with the at least one ferromagnet or the at least one second permanent magnet in such a way that play-dependent relative movement between the operating element and the plunger guided in the operating element is minimized or prevented. The operating element neither wobbles in the rest position nor is it possible for the operating element to jam or catch when moved from the rest position.

[0020] In the operating device according to the invention, the operating element automatically returns to its rest position. The plunger is guided in the operating element and is subjected to a spring force via the spring element arranged in the operating element. The plunger interacts with a guide that is fixed relative to the operating element and defines the rest position of the operating element.

[0021] If the operating unit is moved from its rest position to another position, the plunger is pressed against the guide by the spring element, whereby the plunger is moved either further into the operating unit or further out of the operating unit, depending on its position along the guide. The permanent magnet, which is stationary in relation to the operating unit and the guide, is arranged in the rest position. Either the ferromagnet, which is not permanently magnetic, or the second permanent magnet is attached to the operating unit. In the rest position, the first permanent magnet attracts the ferromagnet or the second permanent magnet. Any play between the operating unit and the plunger guided in the operating unit does not lead to an unwanted relative movement of the operating unit relative to the plunger when the operating unit is in the rest position and the operating unit is not actuated.Furthermore, jamming or catching of the control panel when operated from the rest position is prevented. Overall, a particularly high-quality haptic experience can be provided in the rest position of the control panel.

[0022] Preferably, the control element is monostable, with a single stable rest position to which the control element automatically returns. In particular, the control element is a shift-by-wire control lever designed as a gear selector lever of an automatic transmission or as a direction selector lever. The invention is preferably used in a monostable gear selector lever or monostable direction selector lever of a motor vehicle, namely a passenger car.

[0023] Preferred developments of the invention will become apparent from the dependent claims and the following description. Exemplary embodiments of the invention are explained in more detail, without being limited thereto, with reference to the drawings. Herein: Fig. 1 a highly schematic view of an operating device according to the invention in a first state; Fig. 2 a highly schematic view of an operating device according to the invention in a second state.

[0024] Fig. 1 and Fig. 2 shows a schematic representation of an operating device 10 according to the invention for a motor vehicle. In the preferred embodiment shown, the operating device 10 has a monostable operating element 11.

[0025] Such a monostable operating part 11 is designed for operation from a rest position, which the operating part 11 in Fig. 1, can be displaced in the direction of at least one, in the embodiment shown two, end stops 12. Fig. 2 shows the control unit 11 in a position displaced from the rest position towards one of the end stops 12.

[0026] Only the Fig. The rest position of the control unit 11 shown in Figure 1 is stable. The positions of the control unit 11 in the area of ​​the end stops 12 are not stable; the control unit 11 returns to its stable rest position automatically.

[0027] According to the Fig. 1 and Fig. In the embodiment shown in Figure 2, the operating part 11 is an operating lever which, in the embodiment shown, is pivotably mounted at one end in a joint 13.

[0028] In the Fig. 1. A plunger 14 is guided into the operating part 11, which is designed as an operating lever. The plunger 14 is subjected to a spring force via a spring element 15. The spring element 15 pushes the plunger 14 out of the operating part 11 against a stop (not shown).

[0029] When moving the control unit 11 from its Fig. 1 in the direction of one of the end stops 12, the plunger 14 is moved along a locking contour 16 of a fixed guide 17 and, depending on the pivoting movement of the operating part 11, is either moved further into the operating part 11 against the spring force of the spring element 15 or is moved further out of the operating part 11 by the spring force of the spring element 15.

[0030] Then, when the control unit 11 and via the control unit 11 the plunger 14 from the Fig. 1, the spring element 15 presses the plunger 14 against the locking contour 16 of the guide 17, so that the plunger 14 touches the locking contour 16.

[0031] In the rest position of the Fig. 1, the plunger 14, as in Fig. 1, be lifted off the locking contour 16, whereby the spring element 14 then presses the plunger 14 against the stop (not shown). However, it is also possible that in the Fig. 1, the plunger 14 contacts the locking contour 16 of the guide 17 or rests against it.

[0032] In order to provide a particularly high-quality haptic quality for the operating device 10 according to the invention in the rest position of the operating part 11, it is provided according to the invention that in the region of the rest position, which is provided by the guide 17, namely the locking contour 16 thereof, at least one first permanent magnet 19 which is stationary with respect to the guide 17 and the operating part 11 is arranged.

[0033] According to the invention, at least one ferromagnet 20 or at least one second permanent magnet is firmly connected to the operating part 11, wherein in the embodiment shown the Fig. 1 and Fig. 2, a non-permanent magnetic ferromagnet 20 is permanently connected to the control unit 11. However, at least one second permanent magnet can also be permanently connected to the control unit 11, which has an opposite polarity to the at least one first permanent magnet 19.

[0034] In the Fig. 1, the first permanent magnet 19 attracts the ferromagnet 20 attached to the operating part 11 and, in the rest position, minimizes or prevents a play-dependent relative movement between the operating part 11 and the plunger 14 guided in the operating part 11. Fig. 1 and Fig. 2 it can be seen that a gap is formed between the operating part 11 and the plunger 14, which defines the play between the operating part 11 and the plunger 14.

[0035] Through the interaction of the first permanent magnet 19 with the Fig. 1, Fig. 2 or alternatively with a second permanent magnet, the play-dependent relative movement between the operating part 11 and the plunger 14 is prevented, in particular when the operating part 11 is not actuated.

[0036] When the control unit 11 is not actuated, this prevents any wobbling movement between the control unit 11 and the plunger 14. Furthermore, jamming or catching of the control unit 11 when actuated is prevented.

[0037] In the embodiment shown, a single first stationary permanent magnet 19 is arranged in the area of ​​the guide 17, namely in the area of ​​the rest position defined by the guide 17. Furthermore, in the embodiment of the Fig. 1 and Fig. 2 a single, ring-shaped ferromagnet 20 is connected to the operating part 11, wherein the plunger 14 extends through this ring-shaped ferromagnet 20.

[0038] It is possible to arrange several first permanent magnets 19 in the rest position area. It is also possible to connect several ferromagnets 20 or several second permanent magnets to the operating part 11, which are then arranged around the plunger 14, preferably equally spaced or equidistant.

[0039] The invention enables the provision of high-quality haptics for an operating device 10 with a pivotable operating part 11, in particular a monostable operating part 11, in the rest position of the operating part 11.

[0040] The control element 11 or the control lever is preferably a gear selector lever of an automatic transmission or a direction selector lever, as is common in electric vehicles without a manual transmission. The control element 11 is preferably a shift-by-wire control lever.
