Description

Technical Field

[0001] The invention relates to an operating mode selection device in a motor vehicle. The invention also relates to a motor vehicle having such an operating mode selection device. Background Art

[0002] Compared to vehicles with internal combustion engines, electric vehicles generally no longer require a transmission in the drive train. Therefore, a transmission shift lever or a selector lever is no longer required. However, electric vehicles also require the possibility of selecting the operating mode of the drive device of the electric vehicle, for example for forward driving, for reverse driving or also for parking. Although such a selection can be made on a touch screen, it is desirable for reasons of humanization and also for reasons of driving safety to be able to select the operating mode via a discrete operating device that is provided for this purpose.

[0003] It is generally known that in motor vehicles equipped with an internal combustion engine and an automatic transmission, the drive position is electrically selected by means of a lever that can be tilted back and forth in the vertical longitudinal plane of the vehicle. In addition, in the case of a mechanical transmission, a parking position of the transmission is provided that can be engaged by a separate button, and an electrical parking brake that can be actuated by means of a further button is additionally and separately provided. Summary of the invention

[0004] The object of the present invention is to provide an improved, intuitively operable operating mode selection device for a motor vehicle, in particular for an electrically driven motor vehicle. In addition, a motor vehicle is to be provided which is equipped with such an operating mode selection device.

[0005] The part of this object which relates to the operating mode selection device is achieved by the features of claim 1 .

[0006] An operating mode selection device in a motor vehicle is provided with an operating element, which is connected or coupled to an electrical switch device in order to operate the switch device. Such an operating mode selection device is characterized according to the invention in that the operating element can be moved along a first spatial axis to select at least one operating mode of the motor vehicle and can be moved along a second spatial axis orthogonal to the first spatial axis to select at least one driving position of the motor vehicle.

[0007] In the case of such an operating mode selection device according to the invention, it is advantageous that both the selection of the drive position and the selection of the operating mode are combined in a single operating element, thus allowing intuitive operation.

[0008] Advantageously, the electrical switching device has for this purpose stationary electrical contacts and movable electrical contacts, the movable electrical contacts being formed on a movable contact body so that they can enter into conductive contact with the stationary electrical contacts or disengage from the stationary electrical contacts during actuation, the movable contact body being provided with the actuating element or being coupled to the actuating element.

[0009] Further preferred and advantageous features of the operating mode selection device according to the invention are the subject matter of dependent claims 2 to 9 .

[0010] Preferably, the first spatial axis extends in the vehicle transverse direction and the second spatial axis extends in the vehicle longitudinal direction. Intuitive operability is thereby increased, since the selection of the driving direction corresponds to a displacement of the operating mode selector along the vehicle axis, the operating mode selector moving forwards, for example, determining the forward driving direction, and the operating mode selector moving backwards, for example, determining the reverse direction. Conversely, the movement in the vehicle transverse direction allows the selection of the operating mode itself at a higher level, which switches between a parking operating mode and a driving operating mode, in which, for example, the parking brake of the motor vehicle is activated. Preferably, the first and second spatial axes here form a horizontal plane.

[0011] It is particularly advantageous if the movability of the actuating element along the first spatial axis is formed by a sliding guide of the actuating element and the movability of the actuating element along the second spatial axis is formed by a sliding guide or a tilting bearing of the actuating element. The resulting sliding movement of the actuating element in the vehicle transverse direction and optionally also in the vehicle longitudinal direction or, alternatively, a tilting movement of the actuating element in the vehicle longitudinal direction (i.e. about the vehicle transverse axis) when actuating the operating mode selector facilitates intuitive operation and allows "blind" actuation of the operating mode selector without the driver having to take his eyes off the road.

[0012] According to a preferred embodiment of the invention which can be combined with other embodiments, the electrical switching device has at least one electrical switching function in order to select the at least one operating mode by displacement of the operating element along the first spatial axis, the electrical switching function causing, for example, a switch between a parking mode and an idle position of a driving operating mode of the motor vehicle. Such a switching function ensures that the electrical switching device respectively assumes a defined position associated with the respective operating mode, from which position the switching device can only be moved again in a targeted manner and by intentional actuation of the operating element.

[0013] For selecting the driving position, the electrical switch device can have at least one electrical switching function so that the at least one driving position is selected by displacing the operating element along the second spatial axis. The corresponding driving position then also takes up a defined position, which forms a latching position, for example.

[0014] In an alternative embodiment of the invention, which can also be combined with other embodiments, it is provided that the electrical switching device has at least one electrical pushbutton function for selecting the at least one drive position by displacement of the operating element along the second spatial axis, the pushbutton function causing the activation of the drive position of the motor vehicle. In this case, the selection of the respective drive position is caused by a sliding movement of the operating element, similar to a classic sequential shifting or motorcycle shifting, wherein the operating element respectively rebounds into an intermediate initial position (neutral position) after an actuation.

[0015] It is also particularly advantageous if the electrical switch device respectively effects an electrical pushbutton function in two opposite directions in order to select the at least one drive position by displacement of the operating element along the second spatial axis, wherein displacement of the operating element in the direction of travel activates the forward drive position and displacement of the operating element counter to the direction of travel activates the reverse drive position. Intuitive operation is thus also achieved since the actuation direction of the operating element corresponds to the desired direction of travel.

[0016] A refinement of the invention is particularly advantageous in which a displacement of the operating element along the second spatial axis is possible only in the driving operating mode position of the operating element, thus achieving a defined functional separation between the parking operating mode and the driving operating mode.

[0017] In yet another further embodiment of the invention, which can also be combined with other embodiments, it is provided that the movement path of the operating element along the first spatial axis at least in one movement direction for selecting the at least one operating mode has a lock that acts when the operating element is displaced and / or a force threshold or brake to be overcome when the operating element is displaced. For this purpose, a mechanical lock is preferably provided, which in the locked state prevents switching between operating modes, in particular preventing a change from a driving operating mode position to a parking operating mode position. This locked state can be cancelled, for example, by actuating a further operating device, such as a foot brake pedal.

[0018] As an alternative or supplement to such a locking device, a force threshold value that can be slid over by increased force expenditure can be specified on the sliding path in the vehicle transverse direction. Such a force threshold value can act in two sliding directions (from left to right and from right to left).

[0019] Alternatively, such a force threshold that can be overcome by increasing the sliding force expenditure can be specified only in the sliding direction from the parking mode position to the driving mode position, while for the opposite sliding direction (from the driving mode position to the parking mode position) a mechanical locking device that can be released again separately mentioned above is specified.

[0020] It is particularly advantageous if the movement path of the operating element along the second spatial axis for selecting the at least one driving operating mode has a force threshold to be overcome when the operating element is displaced, which force threshold accordingly forms a pressure point. This prevents the drive stage from being engaged inadvertently, since the operator would need to intentionally overcome the pressure point with increased sliding or tilting force.

[0021] Furthermore, the present invention is directed to a motor vehicle according to claim 10 which is equipped with an operating mode selection device as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Preferred embodiments of the invention together with additional design details and other advantages are described and explained in more detail below with reference to the accompanying drawings.

[0023] The attached pictures are as follows:

[0025] Figure 2 A top view of the operating mode selector device in a second operating mode position (driving operating mode—neutral) with an associated force-displacement diagram;

[0026] Figure 3 In Figure 2 The side view in the direction of arrow III shows Figure 2 An operating mode selection device with an associated force-displacement diagram. DETAILED DESCRIPTION

[0027] Figure 1 In the top view, the operating mode selection device 1 according to the invention is shown in the upper region, which is arranged in a motor vehicle 2, which is only schematically illustrated here. The operating element 10 is arranged in the interior of the motor vehicle 2 above a plate 20 with a visible surface 21 and is connected to an electrical switching device 12, which is arranged below the plate 20 and is only schematically illustrated in the drawing.

[0028] For this purpose, the electrical switching device 12 has at least one movable contact body with an electrical contact, which is mechanically coupled to the operating element 10 by means of a coupling element 13, which is only schematically shown, and which forms a movable electrical contact of the switching device 12 and cooperates with a stationary electrical contact of the electrical switching device 12 in a manner generally known to a person skilled in the art by bringing the movable electrical contact into electrically conductive contact with the stationary electrical contact or out of engagement with the stationary electrical contact. The switching device 12 can thus be operated by sliding and / or tilting the operating element 10.

[0029] The operating element 10 is formed by an elongated rectangular sliding button 11 which is shaped in the manner of a hip roof and has an inclined operating surface 11 ′, 11 ″, 11 ′″, 11 ″″ on each of its four sides.

[0030] The operating element 10 is Figure 1 2 shows that in a first operating mode position (parking operating mode), the operating element can be slid to the left and to the right (relative to the driving direction F) along a first spatial axis y extending in the vehicle transverse direction Y in the direction of the longitudinal extension of the operating element in order to select at least one operating mode of the motor vehicle 2 (parking operating mode "P" or driving operating mode "D"), such as by Figure 1 The slidability of the operating element 10 along the first spatial axis y is formed by a sliding guide 22 of the operating element 10, for example by a slot 23 provided in the plate 20 and extending in the direction of the first spatial axis y, in which the coupling element 13 is guided.

[0031] When the actuating element 10 is turned to the right (relative to the direction of travel F) along the first spatial axis y from the position indicated at Figure 1 Parking mode "P" in the display Figure 2 In the movement path of the driving operating mode "D" in which the operating element occupies the neutral position or the idle position "N", a force threshold value K1 is to be overcome, which has a force edge K1 which gradually increases along the path. A , as in Figure 1 This can be seen in the force-displacement graph in the lower area.

[0032] exist Figure 2 Display Figure 1The operating mode selection device 1 of FIG. 1 is shown in which the operating element 10 is in its second operating mode position (driving operating mode) “D”. When an attempt is made to slide the operating element 10 back from the second operating mode position “D” to the first operating mode position “P”, a lock acts which builds up a high locking force K2 which cannot be overcome by the operating element 10, as in the case of Figure 2 . For this purpose, for example, a mechanical locking device (not shown) is provided, which in driving operating mode "D" is placed in the sliding path of the operating element 10, blocks this path and thus creates a locked state. This locked state is canceled, for example, by actuating the foot brake pedal and thus causing the locking device to be pulled back from the sliding path.

[0033] In driving operating mode “D”, the operating element 10 can be switched from the Figure 2 The neutral position or idle position in the vehicle moves forward (in the driving direction F) and backward (counter to the driving direction F) along the second spatial axis x extending in the longitudinal direction X of the vehicle, as in Figure 3 , in order to engage the driving stage forward or rearward. The operating element 10 can be slid forward and rearward along the second spatial axis x for this purpose, as shown in FIG. Figure 2 The double arrow B in FIG. 1 schematically illustrates the operation of the actuator, or the operating element can be supported in a tilting manner and can be tilted forward and backward about a tilting axis y1 extending parallel to the first spatial axis y, such as by Figure 3 The movability of the operating element 10 along the second spatial axis x is formed by a sliding guide or a tilting guide 24 of the operating element 10, for example, by a sliding slot 25 ( Figure 2 ) or through a shorter flip slot 25'( Figure 3 )form.

[0034] In the description of Figure 3 In the tilting variant in , the actuating element 10 is designed to be pivotable back and forth along a tilting slot 25 ′ by means of a coupling element 13 which forms a tilting bearing 26 and can be tilted about a tilting axis y1 .

[0035] The electrical switch device 12 has front and rear electrical pushbutton contacts (not shown) for forming an electrical pushbutton contact function. The electrical switch device 12 is actuated by displacing the actuating element 10 in a sliding or tilting manner along the second spatial axis x in the driving direction F for selecting at least one forward drive position "V", and by displacing the actuating element in a sliding or tilting manner along the second spatial axis x in the opposite direction of the driving direction F for selecting the reverse drive position "R". The movement path W of the actuating element 10 in the driving direction F along the second spatial axis x is V and the movement path W of the operating element 10 counter to the direction of travel F R Both during sliding and during tilting, there is a front force threshold K3 or a rear force threshold K4 to be overcome, which each form a pressure point that has to be overcome before the associated key contact closes at the path point W3 or W4 and allows the corresponding current to flow, which in turn causes the relevant driving stage to be engaged.

[0036] The operating mode selection device 1 according to the invention therefore allows safe and intuitive single-handed operation of not only the operating mode of the motor vehicle 2 but also the various driving stages of the motor vehicle by means of an operating element 10, which can be moved in a plane, preferably a horizontal plane, along a first spatial axis and a second spatial axis orthogonal to the first spatial axis.
