CAPACITIVE SENSOR ARRANGEMENT FOR SWITCHING A DOOR OPENING ON A MOTOR VEHICLE

摘要

The invention relates to a sensor arrangement for sensing movement gestures close to a motor vehicle, comprising a capacitive sensor electrode (2; 12) and at least one control and evaluation device (4) which is coupled to the sensor electrode and which senses a change in the capacitance of the sensor electrode. The sensor electrode (2; 12) is embodied as an elongate flat electrode, whereby in the longitudinal direction, sensitive electrode sections (a) having a first surface width alternate with less sensitive sections (b) having a second, narrower surface width such that electrode surfaces, which have different levels of sensitivity, different measurements and which are continuously conductive in sections, are formed.
