Method for detecting an actuating motion for an actuator of a motor vehicle equipment element and actuator of a motor vehicle equipment element
First Claim
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.

Abstract
The present invention provides a method for detecting motion for the sensor controlled activation of an operating device for at least one motor vehicle equipment item having at least two capacitive sensors with overlapping detection zones, which provide signals to a control device to control the equipment item. The method comprises the determination of at least one direction of the operating motion within the overlapping detection zones as a valid motion direction for actuating the vehicle equipment item.
