Description

[0018] An embodiment of the invention is shown in the drawings.

[0019] In detail show

[0020] FIG. 1 a schematic perspective view of a sensor unit,

[0021] FIG. 2 a block diagram of the sensor unit and its connections and

[0022] FIG. 3 a perspective view to a car door.

[0023] The sensor unit 1 in FIG. 1 has housing 2 and a cover 3. The cover 3 is shaped equally to a door sealing of the car (not shown) and has a window 4 for a sensor in the sensor area 5. In the housing are located a printed circuit board (PCB) 6, i.e. a flexible PCB, a NFC antenna 7 and the sensor area 5.

[0024] Connected to the PCB 6 there is another flexible PCB 8 which leads to an electronic module 9 arranged in the car door. In a distance to the sensor unit 1 a mobile phone 10 is shown to illustrate the use of the sensor unit 1.

[0025] In FIG. 2 the electronic module 9 is shown with connections 12 to a DCU 13 and an electronic control unit for car access 14. On the other side the electronic module 9 is connected with connections 11 to the NFC antenna 7 and the touch and/or proximity sensor in the sensor area 5. So the electronic module 9 can detect the proximity illustrated by the dotted line 17 of an object like the mobile phone 10, a car key, a smartcard, etc. and/or communicate via the NFC-connection 18. After the detection of the proximity of the object, i.e. the mobile phone 10 the NFC-communication 18 is started.

[0026] In FIG. 3 the position and form of the sensor unit 1 in the car door 15 is illustrated. The sensor unit 1 is prolonging a door sealing 16 and has the same shape as the door sealing 16.

[0027] With such a sensor unit 1 a keyless touch and/or proximity unlock or release combined with the possibility of a smart access is realized, wherein the sensor system is usable to enable the opening of any car door 15, however especially of car doors without door handle and the sensor system is integrated into the visible surface of a door sealing 16.
