[0048] In the following figures, identical reference signs are used for the same technical features even from different embodiments.
[0049] FIG. 1 shows a three-dimensional view of an inventive authentication system 10 for a vehicle 100, in particular for a motor vehicle 100. The authentication system 10 advantageously comprises a one-piece outer housing 11, which is provided with only one opening 12. This opening 12 is used to arrange the electronic unit 20 as well as an inlay 60 for mechanical fixation of the ID-transmitter 80 inside the outer housing 11. It is advisable to close the opening 12 of the outer housing 11 by at least one closing element 13, in this case two closing elements, namely a first 13.1 and a second closing element 13.2. The two closing elements 13 are connected by a fastening element 14, in particular in the form of a screw. To accommodate the ID-transmitter 80 securely and inaccessibly in the outer housing 11 of the authentication system 10, an electronic security unit is provided which monitors the secure storage within the outer housing 11.
[0050] In the following figures, individual components of the inventive authentication system are presented in more detail.
[0051] For example, FIG. 4 shows an electronic unit 20 inside the outer housing 11 for the authentication system 10. It is additionally equipped with an actuating mechanism 40 for mechanical actuation of the ID-transmitter 80 (see FIG. 7). This electronic security unit comprises at least two printed circuit boards 26, namely an upper 26.1 and a lower printed circuit board 26.2, which are connected to each other via electric connections. On the upper printed circuit board 26.1, electronic components can be seen which may form part of the electronic security unit 22. In addition, these electronic components may also form various interfaces 21. In addition, this electronic unit 20 also comprises a drive 25 which serves to drive the actuating mechanism 40 for the ID-transmitter 80 (see FIG. 7). Various monitoring sensors 23 can also be arranged on these printed circuit boards 26 of the electronic unit 20, which, for example, monitor the security fit of a fastening element, in particular the screw for the closing element 13, in the closed position. This can be a mechanical button 80.1, for example. In addition, the monitoring sensors 23 can also comprise light sensors, acoustic sensors or motion and acceleration sensors, through which theft and manipulation attempts can be directly detected by measurement and transmit corresponding status signals to the electronic security unit. If the electronic security unit is switched on in the monitoring mode, an alarm signal can be generated. The lower printed circuit board 26.2 of the electronic unit 20 can be designed as an interference signal transmitter with a corresponding coil printed on it. By means of this interference signal transmitter it is possible to completely interfere with a signal of the external ID-transmitter 80 arranged above it. This means that the ID-transmitter 80 is then not able to effectively transmit an opening signal for the central locking system or a release signal for the engine management system or the immobilizer of the vehicle 100. Below the lower printed circuit board, a fixing element 15 in the form of a mounting plate 15 is indicated, which can be positioned or fixed by holding means, in particular in the form of engaging means on the outer housing 11 of the authentication system 10. By means of a corresponding monitoring sensor 23, in particular in the form of a Hall sensor, or a pressure sensor, the corresponding holding means for connecting the fixing element 15 to the outer housing 11 can be monitored by measurement for their proper fit or position.
[0052] FIG. 2 shows for example an inlay 60 for mechanical fixation of the external ID-transmitter 80. This inlay 60 serves to position the external ID-transmitter 80 locally within the outer housing 11. Ideally, a receiving region 61 inside the inlay 60 is provided for this purpose, which is geometrically complementary to the outer shape of the ID-transmitter 80 in order to be able to reliably fix the ID-transmitter 80 mechanically inside the inlay 60. To ensure that the ID-transmitter 80 is always electrically operable, a battery adapter 62 can be provided which supplies the ID-transmitter 80 with voltage from the authentication system 10. The corresponding battery adapter 62 is shown in FIG. 2 with the connecting wires and the contact lugs for contacting the electronic unit 20. With this battery adapter 62, it is also possible to cause destruction of the ID-transmitter 80, in particular of the electronics of the ID-transmitter 80 by an overvoltage.
[0053] FIG. 3 shows an exemplary ID-transmitter 80 on the left in front view and on the right in back view. The front view shows the buttons 80.1 and a display 80. These buttons 80.1 can be mechanically operated within the authentication system 10 by the actuation mechanism 40 (see FIG. 7). Only the corresponding actuation signal must be present, whereupon the electronic unit 20 controls the actuation mechanism 40 via a drive 25 and thus acquires a purely mechanical actuation of the ID-transmitter 80. As can be seen from the back side of the ID-transmitter 80, it comprises a battery compartment in which the battery adapter 62 can be arranged for a permanent voltage supply.
[0054] FIG. 1 also shows the closing state II of the authentication system 10, wherein the inlay 60, indicated by a dashed line, is inserted through the opening 12 of the outer housing 70 for mechanical fixation of the ID-transmitter 80 (see FIG. 4). The inlay 60 is secured in its corresponding position (in the closing state II) inside the outer housing 11. It is advisable to provide this inlay 60 with fastening means 14 which engage with the outer housing 11 from inside, preferably independently. These fastening elements 14 can be monitored accordingly by the monitoring sensors 23 provided. A change in the position of the fastening elements then leads to a status signal at the monitoring sensors 23, which transmit this to the electronic security unit 22, whereupon an alarm signal is generated if necessary.
[0055] FIG. 4 shows the authentication system 10 from FIG. 1, but without the inlay 60 for the mechanical fixation of the ID-transmitter 80. Hereby, the electronic unit 20 is pre-mounted with the actuating mechanism 40 and the interference signal transmitter in the dashed outer housing 11 of the authentication system 10. In the gap between the upper printed circuit board 26.1 and the lower printed circuit board 26.2 of the electronic unit 20, the inlay 60 can be arranged for the mechanical fixation of the ID-transmitter 80 so that the external ID-transmitter 80 can also be arranged directly above the lower printed circuit board 26.2. In addition, the actuating mechanism 40 with its tappets 43, 44 can act mechanically on the buttons 80.1 of the ID-transmitter 80 from above. FIG. 4 also shows exemplary positions for the monitoring sensors 23. The electronic unit 20 can also be fixed by means of fastening elements, in particular holding and/or engaging elements inside the outer housing 11 of the authentication system 10. At the same time, the electronic unit 20 also comprises a closing element 13, just like the inlay 60 for mechanical fixation of the ID-transmitter 80. With the two closing elements 13, the opening 12 in the outer housing 70 can thus be completely closed.
[0056] FIG. 5 shows a bottom view of the authentication system 10 from FIG. 1. Thereby, the fixing element 15 is already mounted in the form of a mounting plate. Usually, the mounting plate is first fastened to the vehicle 100, e.g. by screwing or riveting, and then the authentication system 10 is mounted by pushing on the outer housing 11. The fixing element 15, in particular the mounting plate, is equipped with holding means that generate a mechanical connection between the fixing element 15 and the outer housing 11. This mechanical connection can also be reliably monitored by measurement in the mounting position I by the monitoring sensors 23 provided. Thus, even the removal of the outer housing 11 from the fixing element 15 results in an alarm of the authentication system 10.
[0057] FIG. 6 shows the back side of the authentication system 10 with various plugs 24 for connection to a vehicle-side electronic system. In the region of the bottom, the pre-mounted fixing element 15, which is surrounded by the outer housing 70 from at least three sides in a form-locking manner, is shown. Ideally, the plug connections on the back side should also have engaging means to prevent these plug connections in the vehicle 100 from being shaken loose by the corresponding vibration in the vehicle 100. As can be seen from FIG. 6, the entire outer housing 11 is closed in itself except for the opening 8. This outer housing 11 is also formed by a one-piece injection molded plastic part. In order to make mechanical breaking-open more difficult, additional reinforcing elements can be provided on or inside the outer housing 11.
[0058] FIG. 7 shows a schematic sectional view of the mechanical actuating mechanism 40 with its drive wheel 41 and at least two actuating tappets 43, 44 for the external ID-transmitter 80 on a drive shaft 42. For a secure operation of its buttons 80.1, the ID-transmitter 80 is fixed within the inlay 60. The mechanical actuation (for operation) of the buttons 80.1 of the ID-transmitter 80 is performed via the two (preferably eccentric) actuating tappets 43, 44 which are driven by the drive shaft 42. The drive wheel 41.2 of the actuating mechanism 40 is driven by a worm wheel 41.1 by the electric drive 25. The drive 25 itself is controlled by the electronic unit 20. This is done by a wireless actuation signal which is transmitted from outside via the first interface 21.1 to the authentication system 10.
[0059] FIG. 8 shows an inventive vehicle 100 with the authentication system 10 according to the invention. By means of the mobile communication device, a release code can be generated for the vehicle 100, wherein the help of an external server can also be used if necessary. To prevent the ID-transmitter 80 from lying loose in the vehicle 100, the authentication system 10 is also arranged inside the vehicle 100, in which the ID-transmitter 80 can then be inserted.
[0060] The above explanation of the embodiments describes the present invention exclusively in the context of examples. Of course, individual features of the embodiments can be freely combined with each other, if technically reasonable, without leaving the scope of the present invention.
