Method for detecting an actuating movement for an actuating device of a motor vehicle trim element and actuating device of a motor vehicle trim element

摘要

The present invention provides a method for detecting an actuation movement (G1, G3) for sensor-controlled activation of an actuation device for at least one motor vehicle equipment element, which has at least two capacitive sensors (S1, S2) with overlapping detection areas (E1, E2), the signals provide to a control unit for controlling the equipment element. The method first comprises defining at least one direction of the actuation movement (G1, G3) within the overlapping detection areas (E1, E2, E4) as a valid direction of movement for actuating the motor vehicle equipment element. This is followed by the detection of a movement (G1, G2, G3, G4) by the detection areas (E1, E2, E4) of two sensors (S1, S2) and the determination of a total duration (tges) of the movement (G1, G2, G3, G4 ) through the detection areas (E1, E2, E4) with the control device and the detection of an overlap duration (t12, t24) of the movement (G1, G2, G3, G4) in an overlap area (E12, E24) of the overlapping detection areas (E1, E2 , E4), whereupon a quotient is calculated from the overlap duration (t12, t24) and the total duration (tges), which is compared with a predetermined limit value which separates a validity range from an invalid range, the limit value being determined by a ratio of a route section through the Total overlap aligned total distance is determined by the detection areas (E1, E2, E4). Finally, the movement (G1, G2, G3, G4) is recognized as an actuating movement (G1, G3) with a valid direction of movement if the quotient is in the valid range. Furthermore, a sensor-controlled actuating device for a motor vehicle equipment element and a motor vehicle equipped therewith are disclosed.
