Abstract
An operating device includes a first operating element with which a user can select one or numerous main functions of a vehicle and that can rotate about an axis of rotation and has at least one predefined fixed rotational position. A second operating element with which a user can adjust subfunctions of the main function can rotate about the axis of rotation and also comprises an actuator unit that comprises a magnetorheological medium configured to exert a retaining force on the second operating element based on a viscosity of the magnetorheological medium. The actuator unit is configured to set the viscosity on the basis of the main function selected with the first operating element, and on the basis of a rotational position of the second operating element.
Claims20
An operating device for a vehicle, comprising:
- a first operating element with which a user can select one of a plurality of main functions of a vehicle, wherein the first operating element is configured to rotate about an axis of rotation, wherein the first operating element has at least one predefined fixed position;
- a second operating element with which a user can adjust at least one subfunction of the main function selected with the first operating element, wherein the second operating element is configured to rotate about the axis of rotation;
- and
- an actuator unit comprising a magnetorheological medium, which is coupled to the second operating element and is configured to exert a retaining force on the second operating element on a basis of a viscosity of the magnetorheological medium,
- wherein the actuator unit is configured to set the viscosity of the magnetorheological medium on a basis of the main function selected with the first operating element and on a basis of a rotational position of the second operating element.
A method for operating a vehicle comprising:
- detecting, by a detection device, a rotational position of a first operating element in an operating device of the vehicle, wherein the first operating element is configured to rotate about an axis of rotation and has at least one predefined fixed position;
- adjusting, by an actuator unit, a viscosity of a magnetorheological medium in the actuator unit on a basis of the detected rotational position of the first operating element;
- exerting, by the actuator unit, a retaining force on a second operating element of the operating device on a basis of the viscosity of the magnetorheological medium;
- detecting, by the detection device, a rotational position of the second operating element in the operating device;
- and
- determining a control signal for controlling the operation of the vehicle on the basis of the detected rotational position of the first operating element and the detected rotational position of the second operating element.
