KAPAZITIVE ANNÄHERUNGSSENSORANORDNUNG AN EINER TÜR EINES KRAFTFAHRZEUGS ZUM ERFASSEN EINER NÄHERUNGSWEISE HORIZONTALEN ANNÄHERUNGSBEWEGUNG EINER BEDIENERHAND
A capacitive proximity sensor arrangement (8) on a door (2) of a motor vehicle for detecting an approximately horizontal approaching movement of an operator's hand is arranged in an outer wall adjacent to a handle edge (6A; 3) to be gripped from behind by the operator's hand. At least two electrode arrangements are arranged spaced apart next to one another in an area in the approximately horizontal direction of movement (7), to be detected, of the approaching movement. Each of the electrode arrangements consists of an elongate electrode (10, 11, 12) extending in a transverse direction to the approximately horizontal direction of movement (7) or of a chain of electrodes extending in said transverse direction, wherein each electrode (10, 11, 12) has a sensor capacity in relation to a reference potential (15). An evaluating circuit (14) for detecting changes in the sensor capacities is coupled to the electrodes (10, 11, 12), wherein the dimensions of and distances between the electrodes are selected in such a manner, and the evaluation circuit (14) is configured in such a manner, that the latter detects whether an object is moving in an approximately horizontal direction with a speed of between 0.2 m/s and 2 m/s past the electrode arrangements in the immediate vicinity thereof and is approaching the handle edge (6A; 3).
