Abstract
A method for detecting motion for sensor-controlled activation of an operating device involves detecting a direction of the operating motion within the overlapping detection areas as a valid motion direction for actuating the vehicle equipment item. A motion through the detection areas of two sensors is detected and a total duration of the motion through the detection areas is determined. An overlap duration of the motion in an overlapping area of the overlapping detection areas is determined. A quotient from the overlap duration and the total duration is calculated and compared with a predetermined threshold separating a valid area from an invalid area. The motion is recognized as an operating motion having a valid motion direction if the quotient is in the valid area.

11. A method for detecting operating motion for sensor-controlled activation of a vehicle equipment item by an operating device comprising at least two capacitive sensors having overlapping detection areas, wherein the method comprises:
-
determining, based on a direction of the operating motion within the overlapping detection areas, that the operating motion is in a valid motion direction; detecting a motion through detection areas of the at least two capacitive sensors; determining a total duration of the motion through the detection areas of the at least two capacitive sensors; detecting an overlap duration of the motion in an overlapping area of the overlapping detection areas; calculating a quotient from the overlap duration and the total duration; comparing the quotient with a predetermined threshold separating a valid area from an invalid area; and determining that the motion is an operating motion with a valid motion direction if the quotient is in the valid area. - View Dependent Claims (12, 13, 14)
