Sensor arrangement for detecting movement gestures of operator at motor car, has control and evaluating device actuating time-shifted sensing electrode portion subsections and separately determining capacitance of subsections

摘要

The sensor arrangement has an elongated capacitive sensing electrode arrangement (3a) comprising sensing electrode portion subsections (4a, 4b), which are axially arranged one behind the other in a longitudinal direction. The subsections are galvanically disconnected from each other. A control and evaluating device (2) is coupled with the subsections such that the control and evaluating device actuates the time-shifted subsections and determines capacitance of the subsections separately and at different times.
