[0001] The invention relates to an operating device for a vehicle, a vehicle and a method for operating a vehicle. Background Art

[0002] For operating vehicle functions, for example, operating elements may be used which can be turned and squeezed by a user in order to navigate through a function menu. Summary of the invention

[0003] Against this background, the invention provides an improved operating device for a vehicle, an improved vehicle and an improved method for operating a vehicle according to the independent claims. Advantageous embodiments result from the dependent claims and the following description.

[0004] According to an embodiment, in particular, an operating device for operating a vehicle or for controlling a vehicle function can be provided with a variable and a static tactile element. In this case, the operating device can be realized, for example, by a combination of a first rotary adjuster with a mechanical stop on the same axis of rotation and a second rotary adjuster with a variable tactile element for intuitive operation of vehicle functions. In this case, an actuator comprising a magnetorheological medium can be used for the second rotary adjuster. Thus, for example, a tactile operating element with a variable tactile element and a static tactile element can be provided, with which a plurality of different functions of the vehicle, in particular driving functions, comfort functions, infotainment functions, etc. in the vehicle, can be intuitively operated. Advantageously, according to an embodiment, a plurality of functions of the vehicle can be operated, in particular, by a compact and intuitive operating unit.

[0005] An operating device for a vehicle comprises: a first operating element, which is used to select one of a plurality of main functions of the vehicle on the user side, wherein the first operating element is supported in a manner that it can rotate about a rotation axis, wherein the first operating element has at least one predefined stable rotational position; and a second operating element, which is used to adjust a subfunction of the main function selected by the first operating element on the user side, wherein the second operating element is supported in a manner that it can rotate about the rotation axis; and an actuator device including a magnetorheological medium, which is coupled to the second operating element and is configured to apply a parking force that depends on the viscosity of the magnetorheological medium to the second operating element, wherein the actuator device is configured to adjust the viscosity of the magnetorheological medium depending on the main function selected by the first operating element and depending on the rotational position of the second operating element.

[0006] The vehicle can be, for example, a motor-driven two-wheeled vehicle, such as a motorcycle or a scooter, a different type of land vehicle, an aircraft or a boat. For example, driving functions of the vehicle, such as transmission functions, chassis functions, lighting functions, etc., comfort functions and infotainment functions can be operated by the operating device. The first operating element and the second operating element can have a common axis of rotation. The parking force depending on the main function selected by the first operating element and the rotational positioning of the second operating element can represent a stop, a change process of the parking force depending on the rotational positioning, and additionally or alternatively represent the arrangement of the parking part depending on the selected main function or the stable rotational positioning of the second operating element. The first operating element can have a static tactile part, which has at least one mechanical parking part tactile part for defining at least one stable rotational positioning. The second operating element can have a variable tactile part, which has a parking part for stable rotational positioning caused by an actuator device depending on the selected main function. The operating element can be formed as a stabilizing bracket, a rotating ring, a rotating adjuster, etc. From the user's point of view, depending on the magnitude of the parking force, the second operating element can be fixed, can be moved easily or can be moved with difficulty, wherein almost any intermediate level can be set by appropriately setting the viscosity of the magnetorheological medium. In this way, the operating force required to move the second operating element can be adapted, for example, to the operating function currently provided by the operating device or to the sub-function of the main function selected accordingly by means of the first operating element. The magnetorheological medium can be a medium comprising magnetically polarizable particles. In particular, it can be a magnetorheological fluid (MRF), which is already used in vehicle applications, for example. Alternatively, it can be a magnetorheological elastomer. The actuator device can be configured to adjust the viscosity of the magnetorheological medium by the magnitude of the magnetic field acting on the magnetorheological medium. The greater the viscosity, the greater the parking force. The magnitude of the parking force can be adjusted by adjusting the viscosity. In this way, a change in viscosity can lead to a change in the parking force.

[0007] According to one embodiment, the first operating element can have a stable rotational position for each main function. Such an embodiment offers the advantage that a reliable selection of the main function can be achieved. Alternatively, the first operating element can be rotated in at least one direction starting from a single stable rotational position in order to switch between the main functions for selection. The main function can be selected here by so-called "toggling" or switching on the main function. After each deflection of the first operating element starting from the stable rotational position, the first operating element can automatically return to the stable rotational position. Here, the next main function can be switched on. Thus, a first operating element that is particularly easy to implement in terms of structure can be provided.

[0008] The first operating element may also have an indicator element for pointing to the selected main function. The indicator element may be shaped as a protruding section that is located beyond the periphery of the first operating element. In this way, the selected main function can be optically identified quickly, simply and reliably on the user side.

[0009] Furthermore, symbols representing the main functions can be arranged on the operating device around the first operating element. The symbols can be printed. Additionally or alternatively, the symbols can be illuminated. Additionally or alternatively, the symbols can be displayed or shown. The symbols can graphically or alphanumerically show the represented main functions. For example, the symbols can be displayed or shown using at least one display or at least one display device. Such an embodiment offers the advantage that, depending on the desired embodiment of the operating device, easily readable symbols can be implemented for the main functions.

[0010] Furthermore, the operating device may have a display unit for displaying sub-functions of the main function selected by the first operating element. Such an embodiment offers the advantage that an intuitive operation of the operating device is possible even without using a further display device of the vehicle. Alternatively, the operating device may be connected to a display of the vehicle in a signal-transmittable manner in order to display the sub-functions of the main function selected by the first operating element.

[0011] Here, the display unit can be arranged in a rotationally fixed manner within the periphery of the second operating element. Such an embodiment provides the advantage that the entire operating device can be compact in structure. Alternatively, the display unit 360 can be integrated into the second operating element 230. Alternatively, the display unit can be arranged outside the operating element. In this way, the operating device can be realized particularly cost-effectively.

[0012] Furthermore, the operating device can have a detection device which is designed to detect a rotational position of the first operating element and a rotational position of the second operating element.

[0013] Here, the detection device can be designed to provide a control signal for controlling the operation of the vehicle using the detected rotational position of the first operating element and the detected rotational position of the second operating element. Such an embodiment provides the advantage that the operation of the vehicle can be controlled intuitively and reliably using the operating device.

[0014] Additionally or alternatively, the actuator device can be designed to adjust the viscosity of the magnetorheological medium as a function of the detected rotational position of the first operating element. Thus, depending on the selected main function, a haptic adapted to the associated subfunction can be realized for the second operating element. The haptic can be adjusted with respect to a number of subfunctions and additionally or alternatively with respect to at least one other characteristic of the subfunction.

[0015] The detection device can also be configured to output the detected rotational position of the first operating element to a display unit of the operating device for displaying a sub-function of the main function selected by the first operating element, or to provide it to the display unit for output. Such a display unit can be configured to display a sub-function of the selected main function using the detected rotational position of the first operating element. As a result, the relevant sub-function can be reliably displayed to the user.

[0016] According to one embodiment, the first operating element and the second operating element can be arranged concentrically and have different radii. Such an embodiment provides the advantage that a compact structure along the axis of rotation can be achieved with simple operability. Alternatively, the first operating element and the second operating element can be arranged coaxially along the axis of rotation in a staggered manner. Thus, a compact structure transverse to the axis of rotation can be achieved for the operating device with simple operability. Furthermore, optionally, the first operating element and additionally or alternatively the second operating element can be shaped in a wrinkled manner on a surface that can be gripped by a user. Such an embodiment provides the advantage that the first operating element and additionally or alternatively the second operating element can be rotated safely and non-slip.

[0017] The vehicle may have the above-described embodiment of the operating device. The operating device may be installed in the vehicle or used to control vehicle functions in order to operate the vehicle.

[0018] The method for operating such a vehicle comprises the following steps:

[0019] detecting a rotational positioning of a first operating element of the operating device;

[0020] adjusting a viscosity of a magnetorheological medium of an actuator device of the operating device using the detected rotational position of the first operating element;

[0021] detecting a rotational positioning of a second operating element of the operating device; and

[0022] Using the detected rotational position of the first operating element and the detected rotational position of the second operating element, a control signal for controlling the operation of the vehicle is determined.

[0023] The steps of the method can be implemented in a suitable device, which can be part of an operating device or, for example, part of a controller of a vehicle. Such a device can be an electrical device that processes electrical signals (for example, sensor signals) and outputs control signals accordingly. The device can have one or more suitable interfaces, which can be constructed in hardware and / or software. In the case of a hardware-side construction, the interface can, for example, be part of an integrated circuit in which the functions of the device are implemented. The interface can also be its own integrated circuit, or at least partially composed of discrete structural elements. In the case of a software-side construction, the interface can be a software module, which, for example, exists on a microcontroller next to other software modules.

[0024] Also advantageous is a computer program product having a program code which can be stored on a machine-readable carrier such as a semiconductor memory, hard disk storage or optical storage and is used for executing the method according to one of the described embodiments when the program is executed on a computer or a device.
