Abstract
A detection system for the approach recognition of a hand or arm movement in the direction a display or control unit. The detection takes place in two stages by way of long-range detection and close-range detection. The first stage detects using at least one optical or acoustic sensor.

14. A detection system for vehicles configured to recognize an approach of an appendage in a direction of an operating unit, comprising:
-
a long range detector comprising at least one of;
at least one optical sensor and at least one acoustic sensor configured for long range detection at a first distance from the operating unit;a close range detector configured for close range detection at a second distance from the operating unit configured for short range detection at the second distance from the operating unit, the second distance being less than the first distance; and an evaluation unit, configured such that the long-range detection automatically triggers the close-range detection when the appendage moves from the long range to the short range. - View Dependent Claims (15, 16, 17, 18, 19, 28, 29)

20. A method for operating a detection system for vehicles for recognizing an approach of an appendage in a direction of an operating unit in a vehicle interior, the system perfoming two-stage detection in which a long-range detector comprises at least one of at least one optical sensor and at least one acoustic sensor, the method comprising:
-
beginning long-range detection with a detection of movement of the appendage in the direction of the operating unit; triggering close-range detection automatically as a result of the appendage movement directly approaching the operating unit. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 30, 31, 32, 33)
