1. 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 that separates 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.
