Operating unit for an in-vehicle system
First Claim
1. An operating unit for an in-vehicle system to control an operation of at least one in-vehicle electric device, comprising:
- a touchscreen;
a rotary knob that is arranged on the touchscreen;
a shaft that extends through the touchscreen, the shaft being non-rotatably connected to the knob;
an electromagnetic latching arrangement with a permanent magnet non-rotatably connected to the shaft and a plurality of electromagnets arranged circumferentially around an axis of rotation of the shaft in a radially outward direction with respect to the axis of rotation, the electromagnetic latching arrangement configured to allow different latched rotary positions of the rotary knob in a non-contact manner relative to the touchscreen; and
at least one electronics assembly connected to the latching arrangement and configured to, in response to a variable function assignment of the rotary knob, control the latching arrangement by varying a number of the plurality of electromagnets to be energized such that an angle of rotation between adjacent latchable rotary positions of the rotary knob is varied.

Abstract
The disclosure relates to an operating unit for an in-vehicle system to control an operation of at least one in-vehicle electric device of a vehicle. The operating unit includes at least one touch screen, at least one rotary knob that is arranged on the touchscreen and at least one shaft that extends through the touchscreen and is connected in a non-rotatable manner to the rotary knob. In order to simplify operation of the operating unit via haptic feedback from the operating unit, the operating unit comprises at least one electromagnetic latching arrangement that is connected to the shaft and renders it possible to latch different rotary positions of the rotary knob in a non-contact manner.

6. An in-vehicle control system comprising:
an operating unit including a rotary knob arranged on a touchscreen and non-rotatably connected to a rotary shaft, the rotary shaft extending through and supported by a radial bearing positioned in a passage defined by the touchscreen, and an electromagnetic latching arrangement configured to electromagnetically latch the rotary knob and rotary shaft in predefined positions relative to the touchscreen without contacting the rotary knob and rotary shaft. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 19, 20)

14. A vehicle, comprising:
-
an in-vehicle control system; and an operating device connected to the in-vehicle control system and being internal to the vehicle, and having a touchscreen and rotary knob on the touchscreen, wherein a shaft extends through the touchscreen such that an electromagnetic latching arrangement, connected to the shaft, allows different, non-contact positions of the rotary knob relative to the touchscreen, the shaft being non-rotatably connected to the rotary knob, wherein the electromagnetic latching arrangement includes a permanent magnet non-rotatably connected to the shaft and a plurality of electromagnets arranged circumferentially around an axis of rotation of the shaft in a radially outward direction with respect to the axis of rotation, the permanent magnet spaced apart from an axis of rotation of the shaft, the permanent magnet having first and second opposite ends, the first end positioned between the axis of rotation and the second end. - View Dependent Claims (15, 16, 17)
