  • Patent number: 8576047
    Abstract: A motor vehicle outside door handle with a wall surrounding an interior space, a first sensor electrode of a first capacitive sensor for triggering a final locking operation, a second sensor electrode of a second capacitive sensor for triggering a locking operation, and an evaluation circuit, which is connected to the first sensor electrode. The second sensor electrode is arranged in the interior space. The first sensor electrode, the second sensor electrode and the evaluation circuit are accommodated in a single sensor module which can be inserted into the interior space. The sensor module has a flat plastic trough which has a bottom wall and is open on one side. A printed circuit board provided with connecting cables is placed into the plastic trough filled with a plastics compound. The sensor electrodes are formed by metal-coated layers of the printed circuit board or by metal bodies mounted on the printed circuit board.

  • Patent number: 8454062
    Abstract: The invention relates to a handle device for a vehicle door, comprising an outer shell with a metal layer at least on the side facing away from the vehicle door and a cavity in which a sensor system for the keyless activation of a locking and unlocking system is arranged. According to the invention, the outer shell (4) has a free surface (7) with no metal layer, provided with a first sensor element (6a) arranged in the sensor system (6a, 6b, 6c), which has a touch- or proximity-sensor embodiment.

  • Patent number: 7151324
    Abstract: The invention relates to an electric steering lock wherein a permanent magnet (20) and two different Hall sensors (21,22) are used to recognise a locking and an unlocking position. The pole transition (23) of the magnet (20) is oriented in the direction of the lift (14). In order to increase efficiency, one sensor (21) is south-pole active and the other (22) is north-pole active. The sensors (21,22) are arranged in an intermediate area (25) between both end positions (10.1, 10.2) of the pole transition (23) of the permanent magnet (20) and are disposed at a defined end distance (38, 39) from both end positions (10.1, 10.2). At said end distance (10.1), the N-active sensor (21) is oriented towards the north pole and the S-active sensor (22) is oriented towards the south pole of the permanent magnet. Said end distance (38, 39) corresponds to the distance at which the magnetic flow density (30.1) of the permanent magnet (20) is at least identical to the threshold value (21.1) required to turn on (28.1, 29.
