AUTHENTICATION SYSTEM AND SECURITY PROCEDURES FOR IT

Description

[0001] The present invention relates to an authentication system of the type defined in more detail in the preamble of the independent apparatus claim. Furthermore, the invention relates to a monitoring method according to the preamble of the independent method claim.

[0002] It is well known that carsharing is becoming increasingly popular, especially in large cities. With carsharing, vehicles are provided by a carsharing provider, which a user can rent to, for example, travel a specific distance or run an errand, such as shopping. The user then returns the vehicle so that it is available for the next user.

[0003] Unfortunately, it is also common practice for the ID transmitter (also called a key) used to open the locking system and start the engine to be located, for example, in the glove compartment of the car-sharing vehicle. However, this makes the ID transmitter easily accessible to a burglar who gains unauthorized access to the vehicle, e.g., by breaking a window. This makes it easy for the burglar to bypass the immobilizer using the ID transmitter located in the glove compartment.

[0004] Furthermore, it is problematic that individual solutions for each user to access the immobilizer, for example via a code provided by the carsharing provider, would require major modifications or expensive alterations to the vehicle. Major modifications could include, for example, installing a special locking system for carsharing operation. However, carsharing vehicles are typically standard production models that are to be converted into carsharing vehicles with minimal effort, thus keeping costs down.

[0005] Further locking systems are known from documents DE 10 2006 001410 A1, which discloses the preamble of claims 1 and 12, and US 6 611 232 B1.

[0006] A disadvantage of known solutions is that the ID transmitter is located unsecured inside the vehicle. It is therefore an object of the present invention to at least partially overcome the disadvantages described above. In particular, it is an object of the present invention to prevent the ID transmitter from being located freely and accessibly inside the vehicle.

[0007] The foregoing problem is solved by an authentication system with the features of the independent device claim and by a monitoring method with the features of the independent method claim. Further features and details of the invention will become apparent from the respective dependent claims, the description, and the drawings. Features and details described in connection with the authentication system according to the invention naturally also apply in connection with the monitoring method according to the invention, and vice versa, so that the disclosure of the individual aspects of the invention is always, or can always be, mutually referenced. The problem is solved in particular by an authentication system for a vehicle, especially a motor vehicle, for storing an ID transmitter in the vehicle, with an external housing in which the ID transmitter can be stored.The system includes an electronic security unit to monitor the secure storage of the ID transmitter within the outer housing. If an unauthorized user attempts to access the ID transmitter from the outer housing, the electronic security unit detects the unauthorized access and triggers an alarm.

[0008] The core of the present invention is that the (external) ID transmitter is secured and adequately housed within the outer casing of the authentication system by the electronic security unit. This means the ID transmitter is not only mechanically but also electrically secured within the authentication system. As soon as an attempted theft and / or tampering with this system occurs, it is detected by the electronic security unit, and a corresponding alarm signal can be triggered. This alarm signal can then trigger at least an audible warning tone, a permanent disablement of the vehicle's immobilizer, or even the destruction of the ID transmitter. Further procedures in the event of an alarm signal are described below. The electrical securing of the ID transmitter by the electronic security unit is particularly reliable and cost-effective to implement.In contrast, mechanically securing the ID transmitter requires a very complex design and choice of materials (hardened metal alloys), comparable to the construction of a small safe.

[0009] In the context of the present invention, the term "authentication system" refers to a system that enables a vehicle to be properly opened and started once the appropriate authentication has been established. This is achieved not by directly activating the vehicle's ID transmitter, but indirectly via the authentication system. Thus, the authentication system acts as an intermediary between the vehicle user and the vehicle's access and authorization system, which includes the corresponding ID transmitter. Advantageously, the authentication system can be opened wirelessly by the user (carsharing driver) using a mobile communication device, such as a mobile phone, tablet, or laptop.In this case, the mobile communication device can communicate directly with the authentication system via a (first) interface and / or indirectly with the authentication system via another interface and an external network or external server.

[0010] The user of the authentication system can communicate with the system via a corresponding release code using their mobile communication device. If the release code and any further authorization requests are successful, the system can then activate the ID transmitter inside the vehicle. The corresponding activation signal can be generated on the mobile communication device and / or a network or server, preferably generated outside the vehicle, for example, based on the release code and any further authorizations such as personal information, credit card details, location, time period, and / or similar information. Only (preferably wireless) communication between the mobile communication device and the authentication system is possible. It is also conceivable that additional or even sole communication occurs between the external network or server and the authentication system.If only the external network or server communicates with the authentication system, communication can take place via the (first) interface. It is assumed that the mobile communication device will first exchange data with the external network or server for authentication purposes, ensuring that the release code and any further authorization requests are successful.

[0011] According to the invention, an electronic unit for the authentication system is provided, wherein the electronic unit has at least one interface through which the ID transmitter can be actuated from outside the authentication system. This interface enables data communication for user authentication between the mobile communication device and / or the external network or server. This interface is preferably a Bluetooth or NFC interface, particularly if communication only takes place between the mobile communication device and the authentication system. A mobile communication interface, such as LTE, UMTS, or the like, can also be provided. Advantageously, encrypted data transmission (at this interface) takes place to make manipulation more difficult.

[0012] Furthermore, it is conceivable that the ID transmitter, preferably mechanically, can be actuated by the authentication system. In this case, an actuation signal for the ID transmitter can preferably be sent to the authentication system from an external source, particularly via an interface. Thus, the ID transmitter is not actuated directly by the user, which is also impossible since it is inaccessible within the authentication system. Rather, after successful authentication (upon presentation of an authorization code), the ID transmitter is actuated indirectly by the authentication system itself in a secure (purely) mechanical manner. This makes the authentication system ideal as a retrofit system for existing production vehicles (for car-sharing vehicles), as no modification of the existing vehicle electronics is required.

[0013] It is also conceivable that an electric drive, particularly for the mechanical actuation of the ID transmitter, is provided within the outer housing, wherein the drive is preferably controllable by the electronic unit, particularly based on an actuation signal received from outside the authentication system. This means that the existing external ID transmitter, which is typically used by the user in standard production vehicles (not yet converted car-sharing vehicles), does not need to be modified. Therefore, the system according to the invention offers a wide range of applications for car-sharing vehicles, as it can be used regardless of the vehicle manufacturer.

[0014] For example, an insert for the mechanical fixation of the ID sensor may be provided, and this insert may be arranged within the outer housing. This insert serves to position the external ID sensor locally within the outer housing. Ideally, a receiving area is provided within the insert, which is preferably geometrically complementary to the outer shape of the ID sensor, in order to securely fix the ID sensor mechanically within the insert. It is also conceivable that the ID sensor can be mechanically actuated by an actuating mechanism, which is preferably driven by the drive. This mechanical actuating mechanism can be designed with its drive wheel and at least two actuating plungers for the external ID sensor, wherein the actuating plungers are preferably arranged on a drive shaft in a rotationally fixed manner (always rotating with the shaft), in particular via a splined connection.The drive wheel of the actuating mechanism is expediently fixed to the drive shaft (and thus also to the actuating plungers) and can be driven by the electric drive via a worm gear. The drive itself can be controlled by the electronic unit. It can also be provided that the ID transmitter's power supply can be provided by a battery adapter, which in particular can be electrically connected to the electronic unit. The battery adapter can also destroy the ID transmitter's electronics in the event of an overvoltage, which can be deliberately generated by the electronic unit. This can be done, in particular, in the presence of an alarm signal, thus preventing any unauthorized user from further using the ID transmitter during a break-in attempt.

[0015] Optionally, at least one locking element may be provided, allowing an opening in the outer housing to be at least partially or completely closed. This ensures that the ID transmitter can only be removed from the outer housing of the authentication system through the opening closed by the locking element. Otherwise, only the destruction of the housing can lead to unauthorized removal of the ID transmitter. Advantageously, the locking element can also serve to mechanically secure the electronic unit within the outer housing. Thus, the locking element can simultaneously fulfill two functions.

[0016] Furthermore, within the scope of the invention, it is conceivable that at least one locking element can be attached to the outer housing in a mounting position by means of at least one fastening element. Thus, the locking element can be securely fixed in the opening of the outer housing. In this case, at least one monitoring sensor (of the electronic security unit) can monitor at least the locking element in its closed position or the fastening element in its mounting position. This allows any unauthorized removal of the fastening element to open the locking element or the opening to be immediately detected by a monitoring sensor.

[0017] The mounting position is the position in which the authentication system is ready for use, secured in the vehicle (by at least one fixing element) and locked (by at least one locking element). In this position, the security unit's monitoring sensors are able to immediately detect any attempted break-in and / or tampering.

[0018] Additionally, it is advantageous if the insert for mechanically securing the ID transmitter is also equipped with a further locking element. In this case, the existing locking elements can jointly close the entire opening of the outer housing in a single mounting position. Both the electronic unit and the insert can be attached to or inside the outer housing by retaining and / or locking devices. These retaining and / or locking devices can interact with the monitoring sensors in such a way that any movement that releases the retaining and / or locking devices triggers a signal from the monitoring sensors. Monitoring of the retaining and / or locking devices can only be deactivated in a so-called workshop mode of the authentication system to allow for maintenance and repair work.Ideally, switching between a monitoring mode, in which the authentication system, particularly the external housing, is actively monitored, and a workshop mode should only be possible externally using a corresponding unlock code (from an external device, network, and / or server). Without this unlock code, unauthorized and undetected removal of the ID transmitter from the authentication system is impossible.

[0019] A further advantage of the invention is achieved if the authentication system has its own power supply, preferably comprising at least one battery, accumulator, or capacitor. This allows the authentication system to operate independently of the vehicle's electronics and / or power supply. Thus, the authentication system's own power supply can operate independently of the vehicle battery. Advantageously, the authentication system's own power supply can be designed to be electrically rechargeable. This allows the power supply to recharge itself and remain functional as soon as energy is supplied from an external source. Therefore, in the event of theft, simply disconnecting the vehicle battery is insufficient, as the authentication system is essentially self-sufficient thanks to its rechargeable power supply.

[0020] Another possibility is that the electronic security unit is part of the authentication system's electronic unit, specifically that the electronic security unit is mounted on a circuit board within the electronic unit. This allows for a cost-effective and space-saving design of the authentication system. Furthermore, it makes tampering more difficult, as it is not immediately apparent which electronic component belongs to the security unit.

[0021] Within the scope of the invention, it is further conceivable that a jamming signal generator, preferably in the form of an antenna, is provided with which a transmit and / or receive signal of the ID sensor can be jammed, wherein, in particular, the jamming signal generator can be controlled by the electronic unit. This jamming signal generator can completely disrupt a signal from the external ID sensor that can be arranged above it. Consequently, the ID sensor is then unable to effectively transmit an opening signal for the central locking system or a release signal for the engine management system or the vehicle's immobilizer. Thus, the ID sensor is rendered inoperative by the transmitted jamming signal.

[0022] Advantageously, the electronic safety unit may be provided with at least one monitoring sensor, and / or preferably, the monitoring sensor may comprise at least one switch, push button, magnetic switch, optical sensor, accelerometer, touch sensor, pressure sensor, force sensor, Hall sensor, temperature sensor, and / or acoustic sensor. The various monitoring sensors provide diverse monitoring options and redundancies to enhance safety. It is also conceivable that at least one monitoring sensor can be positioned independently of the safety unit's location. This allows for particularly flexible deployment.

[0023] It is further conceivable that at least one monitoring sensor, in the event of an attempted theft and / or manipulation of the authentication system, generates at least one alarm signal and transmits it to the electronic security unit, which triggers an alarm signal, at least in monitoring mode. To enable, for example, a repair of the device according to the invention, the workshop mode must first be activated (via remote control).

[0024] Using the integrated monitoring sensors, the electronic security unit is capable of detecting various theft and tampering attempts. For example, a light sensor can optically detect drilling into the housing as soon as light enters the outer casing through the hole. It is also possible to equip at least a portion of the outer casing with a vacuum or pressurized volume that drops to normal ambient pressure as soon as the casing is disturbed at that point by a drilling or other attempt. A pressure sensor can monitor the corresponding overpressure or underpressure for this purpose. Furthermore, an accelerometer inside the outer casing can detect changes in position while the device is at rest (monitoring mode).All these events can cause the monitoring sensors to generate a message signal and send it to the electronic security unit, which then triggers an alarm signal, at least in monitoring mode.

[0025] Furthermore, it is optionally provided that a first interface is included, enabling wireless data transmission to the authentication system, wherein the first interface preferably enables bidirectional data transmission, and / or wherein external control of the authentication system preferably takes place via the first interface, in particular to actuate the ID transmitter, and / or an alarm signal can be transmitted externally. This interface can preferably be a Bluetooth or NFC interface, which enables direct data exchange (in particular encrypted data exchange) with the user's mobile communication device.

[0026] Furthermore, it is advantageous to have a second interface that allows data transmission between the vehicle electronics and the authentication system, preferably for exchanging an alarm signal. This second interface also enables additional security for, for example, the immobilizer from the vehicle's management system or an electric steering lock device.

[0027] According to the invention, a fixing element, in particular in the form of a mounting plate or a housing clamp (similar to a cable tie), is provided for securing the authentication system, especially the outer housing, in the vehicle. Furthermore, at least one retaining means is provided for the mechanical connection between the fixing element and the outer housing in a mounting position, wherein the mechanical connection between the fixing element and the outer housing in the mounting position can be monitored by at least one monitoring sensor. This allows the installation of the authentication system in the vehicle to also be monitored by at least one monitoring sensor of the electronic security unit. As soon as any manipulation is carried out on the mounting plate or a fixing element, this can be detected by measurement and lead to a notification signal and ultimately to an alarm signal.

[0028] In particular, the authentication system can be a remotely controlled key safe in which the ID transmitter can be securely stored. Preferably, the outer housing has a volume of less than or equal to 200 mm x 150 mm x 150 mm. This allows the authentication system to be placed in various locations within the vehicle.

[0029] It is also conceivable that at least two monitoring sensors are present, with preferably a first monitoring sensor monitoring the locking element and a second monitoring sensor monitoring the mounting plate for their respective positions in the mounting position. Further monitoring sensors are also conceivable, such as a light sensor or an accelerometer. The different sensors would allow for the detection of different break-in attempts.

[0030] Preferably, the outer housing is a plastic injection-molded part, preferably incorporating reinforcing elements, particularly made of metal, carbon, and / or glass fiber, on or within the outer housing. Such an outer housing is geometrically complex yet cost-effective to manufacture. It is also possible to seal this outer housing in a pressure-tight, light-tight, and / or dustproof manner. Thus, the outer housing of the authentication system can be completely sealed except for an opening through which the electronic unit with the electronic security unit and the external ID transmitter can be inserted. At least one sealing element can be provided to close this opening. Ideally, the outer housing can be completely sealed except for this single opening.

[0031] Furthermore, it is advantageous if, within the scope of the invention, the monitoring sensors are electrically connected to the fuse unit via at least one connecting cable, whereby the respective connecting cable can also be monitored for tampering, e.g., by resistance measurements. This allows the sensors to be placed and used anywhere within the outer housing.

[0032] The invention also relates to a monitoring method for an authentication system for a motor vehicle for storing an ID transmitter in the vehicle, according to one of the preceding claims, with an outer housing in which the ID transmitter can be stored. It is provided that an attempted theft and / or manipulation of the authentication system triggers at least an alarm signal. Thus, the monitoring method according to the invention offers the same advantages as those disclosed in detail with regard to the authentication system according to the invention.

[0033] Furthermore, it is conceivable that at least one mechanical theft attempt and / or at least one electronic or mechanical manipulation attempt (detected by the monitoring sensors) will be detected and trigger an alarm signal. This alarm could also render the ID transmitter inoperable.

[0034] Preferably, the invention may provide that the monitoring method has at least two operating modes: a) the monitoring mode, in which active monitoring of the authentication system, in particular the outer casing, takes place; b) the workshop mode, in which monitoring is deactivated in order to be able to carry out maintenance and repair work on the authentication system.

[0035] Other operating modes are also conceivable, such as the alarm mode, in which an alarm signal has been triggered.

[0036] Furthermore, within the scope of the invention, it is optionally possible that, at least in monitoring mode, the authentication system can actuate the ID transmitter, particularly mechanically, wherein preferably an actuation signal for the ID transmitter is received from an external source, preferably via an interface, by the authentication system. This makes the method readily suitable for converting standard production vehicles into car-sharing vehicles without any modification to the existing vehicle electronics.

[0037] For example, it may be provided that, in the event of a triggered alarm signal, the ID transmitter, in particular the electronics of the ID transmitter, is destroyed, and / or that, in the event of a triggered alarm signal, a warning signal is sent to the vehicle's management system, preferably blocking an electronic immobilizer, and / or that, in the event of a triggered alarm signal, an acoustic siren is activated, and / or that, in the event of a triggered alarm signal, a warning signal is forwarded to an external assistance server, and / or that, in the event of a triggered alarm signal, the vehicle's lighting system is switched on, and / or an emergency signal is sent to the police or a security service.

[0038] Further advantages, features, and details of the invention will become apparent from the following description, in which exemplary embodiments of the invention are described in detail with reference to the drawings. The features mentioned in the claims and in the description can each be essential to the invention individually or in any combination. The drawings show: Fig. 1 Three-dimensional view of an authentication system according to the invention and the corresponding outer housing in the closed state, Fig. 2 Three-dimensional view of an insert for the mechanical fixing of the ID transmitter with a battery adapter, Fig. 3 Front and back of an external ID transmitter, Fig. 4 Three-dimensional view of an authentication system made of Fig. 1 with electronic unit, including an actuation mechanism for the external ID transmitter and a jamming signal transmitter without an insert for mechanically fixing the ID transmitter, Fig. 5 Bottom view of the authentication system made of Fig. 1 with mounted fixing element, in the form of a mounting plate, Fig. 6 Rear view of the authentication system made of Fig. 1 with a mounting fixing element on the bottom side, Fig. 7 schematic sectional view of an actuating mechanism with a corresponding drive and an ID transmitter within the insert, and Fig. 8 vehicle according to the invention with the authentication system according to the invention and a mobile communication device for control.

[0039] In the following figures, identical reference numerals are used for the same technical features even for different embodiments.

[0040] In the Fig. 1 Figure 1 shows a three-dimensional view of an authentication system 10 according to the invention for a vehicle 100, in particular a motor vehicle 100. Advantageously, the authentication system 10 has a one-piece outer housing 11, which is provided with only one opening 12. This opening 12 serves to accommodate the electronic unit 20 and an insert 60 for the mechanical fixation of the ID transmitter 80 inside the outer housing 11. Advantageously, the opening 12 of the outer housing 11 is closed by at least one locking element 13, in this case two locking elements, namely a first 13.1 and a second locking element 13.2. The two locking elements 13 are connected to each other by a fastening element 14, in particular in the form of a screw.In order to securely and inaccessibly house the ID transmitter 80 in the outer housing 11 of the authentication system 10, an electronic security unit is provided which monitors secure storage within the outer housing 11.

[0041] The following figures illustrate individual components of the authentication system according to the invention in more detail.

[0042] This shows Fig. 4 For example, an electronic unit 20 inside the outer housing 11 for the authentication system 10. This is additionally equipped with an actuating mechanism 40 for the mechanical actuation of the ID transmitter 80 (see below). Fig. 7 This electronic security unit has at least two circuit boards 26, namely an upper circuit board 26.1 and a lower circuit board 26.2, which are connected to each other via electrical connections. Electronic components can be seen on the upper circuit board 26.1, which may constitute part of the electronic security unit 22. These electronic components may also form various interfaces 21. In addition, this electronic unit 20 also has a drive 25, which serves to actuate the actuating mechanism 40 for the ID transmitter 80 (see [reference]). Fig. 7 Various monitoring sensors 23 can also be arranged on these circuit boards 26 of the electronic unit 20. These sensors monitor, for example, the secure fit of a fastening element, in particular the screw for the locking element 13, in the closed position. This could be, for example, a mechanical push button 80.1. Furthermore, the monitoring sensors 23 can also include light sensors, acoustic sensors, or motion and acceleration sensors, which allow for the direct measurement of theft and tampering attempts and transmit corresponding alarm signals to the electronic security unit. If the electronic security unit is switched on in monitoring mode, an alarm signal can be generated. The lower circuit board 26.2 of the electronic unit 20 can be designed as a jamming signal generator with a corresponding coil printed on it.This jamming signal generator makes it possible to completely disrupt the signal of the external ID transmitter 80 that can be arranged above it. Consequently, the ID transmitter 80 is then unable 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. A fixing element 15 in the form of a mounting plate 15 is indicated below the lower circuit board. This element can be positioned or fixed to the outer housing 11 of the authentication system 10 by means of retaining elements, in particular snap-in elements. A corresponding monitoring sensor 23, in particular a Hall sensor or a pressure sensor, can be used to monitor the correct seating and position of the retaining elements for connecting the fixing element 15 to the outer housing 11.

[0043] In the Fig. 2 An insert 60 for the mechanical fixing of the external ID transmitter 80 is shown as an example. This insert 60 serves to position the external ID transmitter 80 locally within the outer housing 11. Ideally, a receiving area 61 is provided within the insert 60, which is geometrically complementary to the outer shape of the ID transmitter 80, in order to securely fix the ID transmitter 80 mechanically within the insert 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 The connecting wires and contact tabs for contacting the electronic unit 20 are shown. With this battery adapter 62, it is also possible to damage the ID sensor 80, in particular the electronics of the ID sensor 80, by means of an overvoltage.

[0044] In the Fig. 3 An example ID transmitter 80 is shown on the left in a front view and on the right in a rear view. The front view shows the keys 80.1 and a display 80. These keys 80.1 can be mechanically actuated within the authentication system 10 by the actuating mechanism 40 (see [reference]). Fig. 7 Here, only the corresponding actuation signal is required, whereupon the electronic unit 20, via a drive 25, controls the actuation mechanism 40, thus achieving purely mechanical actuation of the ID transmitter 80. As can be seen from the back of the ID transmitter 80, it has a battery compartment in which the battery adapter 62 can be arranged for a permanent power supply.

[0045] In the Fig. 1 Furthermore, the locking state II of the authentication system 10 is shown, wherein the insert 60, indicated by dashed lines, is inserted through the opening 12 of the outer housing 70 for the mechanical fixing of the ID transmitter 80 (see also Fig. 4 The insert 60 is secured in its corresponding position (in closed state II) within the outer housing 11. Advantageously, this insert 60 is provided with fastening elements 14 that snap into the outer housing 11 from the inside, preferably independently. These fastening elements 14 can be monitored accordingly by the provided monitoring sensors 23. A change in the position of the fastening elements then leads to a signal at the monitoring sensors 23, which forward this signal to the electronic security unit 22, whereupon an alarm signal is generated if necessary.

[0046] In the Fig. 4 Is the authentication system 10 out of Fig. 1 The diagram shows the electronic unit 20 with the actuating mechanism 40 and the jamming signal generator pre-assembled in the outer housing 11 of the authentication system 10, shown with dashed lines. The insert 60 for mechanically fixing the ID transmitter 80 can be positioned in the gap between the upper circuit board 26.1 and the lower circuit board 26.2 of the electronic unit 20, so that the external ID transmitter 80 can ultimately be positioned directly above the lower circuit board 26.2. Furthermore, the actuating mechanism 40, with its plungers 43, 44, can mechanically act on the buttons 80.1 of the ID transmitter 80 from above. Fig. 4 Exemplary positions for the monitoring sensors 23 are also shown. The electronic unit 20 can also be fixed inside the outer housing 11 of the authentication system 10 using fastening elements, in particular snap-in and retaining elements. The electronic unit 20 also has a locking element 13, as does the insert 60 for the mechanical fixing of the ID transmitter 80. The opening 12 in the outer housing 70 can thus be completely closed with the two locking elements 13.

[0047] Fig. 5 shows a floor view from authentication system 10. Fig. 1 The fixing element 15, in the form of a mounting plate, is already mounted. Typically, the mounting plate is first attached to the vehicle 100, for example by screwing or riveting, and then the authentication system 10 is mounted by sliding the outer housing 11 onto it. The fixing element 15, in particular the mounting plate, has retaining means that create a mechanical connection between the fixing element 15 and the outer housing 11. This mechanical connection can also be reliably monitored in mounting position I by the provided monitoring sensors 23. Thus, even the removal of the outer housing 11 from the fixing element 15 triggers an alarm in the authentication system 10.

[0048] In the Fig. 6 The rear of the authentication system 10 is shown, with various connectors 24 for connection to vehicle electronics. The pre-assembled fixing element 15, which is positively locked to the outer housing 70 on at least three sides, is shown at the bottom. Ideally, the connectors on the rear also have locking mechanisms to prevent these connectors from loosening due to vibrations in the vehicle 100. How well this is achieved is shown in the Fig. 6 As can also be seen, the entire outer housing 11 is sealed except for the opening 8. This outer housing 11 is also formed from a single injection-molded plastic part. To make mechanical break-in more difficult, additional reinforcing elements can be provided on or inside the outer housing 11.

[0049] In the Fig. 7 The schematic sectional view shows the mechanical actuation mechanism 40 with its drive wheel 41 and at least two actuating plungers 43, 44 for the external ID transmitter 80 on a drive shaft 42. The ID transmitter 80 is fixed within the insert 60 for the secure operation of its buttons 80.1. The mechanical actuation (for operation) of the buttons 80.1 of the ID transmitter 80 is effected by the two (preferably eccentric) actuating plungers 43, 44, which are driven by the drive shaft 42. The drive wheel 41.2 of the actuation mechanism 40 is driven by a worm gear 41.1 from 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 externally to the authentication system 10 via the first interface 21.1.

[0050] In the Fig. 8 A vehicle 100 according to the invention is shown, along with the authentication system 10 according to the invention. A release code for the vehicle 100 can be generated via the mobile communication device, optionally using an external server. To prevent the ID transmitter 80 from lying loose inside the vehicle 100, the authentication system 10 is also arranged inside the vehicle 100, into which the ID transmitter 80 can then be inserted.
