1. An operating unit (100) of a vehicle (300), the operating unit (100) comprising:
- a capacitive touch panel (101) configured to receive a user input;
a first capacitive sensor unit (102), the first capacitive sensor unit (102) being configured as a conductor loop;
a second capacitive sensor unit comprising a plurality of capacitive sensors arranged around the capacitive touch panel;
a third capacitive sensor unit comprising a second plurality of capacitive sensors arranged so as to cover the touch panel; and
a first control unit (103),wherein;
the first, second and third capacitive sensor units cooperate to detect an approach of a user to the capacitive touch panel (101),the capacitive touch panel (101) is configured to detect a touch of the capacitive touch panel (101) by the user or the approach of the user to the capacitive touch panel (101),the first control unit (103) is configured to activate the capacitive touch panel (101) if one or more of the first, second and third capacitive sensor units detect the approach of the user to the capacitive touch panel (101), andthe conductor loop being arranged so as to surround the capacitive touch panel (101) such that the capacitive touch panel (101) is arranged entirely within the conductor loop.

Abstract
An operating element in a vehicle includes a capacitive touch panel and a capacitive sensor unit configured to detect a user approaching the touch panel. When the capacitive sensor unit detects the approaching user, a first control unit activates the touch panel, such that the touch panel may be activated from a sleep mode by a single movement, and such that the user can, at the same time, perform inputs using the touch panel.

7. A method for operating an operating device having a capacitive touch panel and first, second and third capacitive sensor units in a vehicle, the method comprising:
-
detecting, by one or more of the first, second and third capacitive sensor units of the operating device, an approach of a user to the capacitive touch panel (S1), the first capacitive sensor unit being configured as a conductor loop arranged so as to surround the capacitive touch panel such that the capacitive touch panel is arranged entirely within the conductor loop, the second capacitive sensor unit comprising a plurality of capacitive sensors arranged around the capacitive touch panel, and the third capacitive sensor unit comprising a second plurality of capacitive sensors arranged so as to cover the touch panel; activating, by a first control unit, the capacitive touch panel if one or more of the first, second and third capacitive sensor units detect the approach of the user to the capacitive touch panel (S2); and receiving, by the capacitive touch panel, a user input by detecting a touch of the capacitive touch panel by the user or by detecting the approach of the user to the capacitive touch panel (S3).
