Description

[0001] The invention relates to a locking system according to the preamble of claim 1.

[0002] For increased security requirements, electronic locking systems are used, which operate, for example, using electromagnetic waves. Particularly in motor vehicles, such locking systems are used as door locking systems for access authorization and / or as ignition lock systems, steering locks, immobilizers, or similar devices for driving authorization.

[0003] Such locking systems are known from DE 43 40 260 A1. The locking system consists of a first device, designed as a control unit for locking and / or unlocking car doors, the ignition lock, or the like, and an associated, operable second device designed in the manner of an electronic key. For their intended operation, both devices have transmitters and / or receivers for transmitting electromagnetic signals. In intended operation, at least one signal can be transmitted between the key and the control unit as a coded operating signal for authenticating the key, so that after a positive evaluation of the transmitted operating signal, and thus with an authorized key, a change in the state of the control unit can be effected.The change in the state of the control device can be triggered by the user manually operating the corresponding actuators on the key.

[0004] Such locking systems have also been further developed with so-called "keyless" functionalities. With the "Keyless Entry" function, manual operation of the electronic key by the user is no longer necessary. It is sufficient for the user to simply carry the key. The operating signal for access authorization is then automatically transmitted between the two systems when the user is within range of the vehicle and, for example, operates the door handle. Similarly, these locking systems can feature a "Keyless Go" function, whereby the operating signal for driving authorization is automatically transmitted between the two systems when the user is inside the vehicle and, for example, presses a start / stop button on the dashboard.

[0005] The locking system known from DE 43 40 260 A1 and the locking systems with keyless functionalities are not intended for use in fleet and / or car sharing applications for motor vehicles, where, for example, an operator makes motor vehicles available to several users for a fee.

[0006] Furthermore, adapters for locking systems with a second device and aspects of such locking systems are known in the prior art, for example from documents DE 10 2015 103 329 A1, DE 10 2012 015 925 A1 and DE 10 2006 001 410 A1.

[0007] The invention is based on the objective of further developing the locking system in such a way that its use in fleet and / or car-sharing applications is possible. In particular, the second device is to be used largely in its current state.

[0008] This problem is solved in a generic locking system by the characterizing features of claim 1.

[0009] The locking system according to the invention includes an adapter for the second device, which can be installed in the vehicle and comprises a remotely controllable actuator for operating the second device. If the vehicle equipped with the locking system is to be used in a fleet and / or car-sharing application, the unmodified second device can interact with the adapter located in the vehicle to operate the locking system. Advantageously, this eliminates the need to adapt the second device for this purpose; rather, the second device supplied with the vehicle as standard can be used without modification. Further embodiments of the invention are the subject of the dependent claims.

[0010] In a further, simpler embodiment, the adapter can be connected to a control unit in the form of control electronics. The control unit can be configured for wireless communication, particularly via electromagnetic carrier waves, with a mobile device, thus advantageously enabling remote control of the control unit. The mobile device can be a mobile phone, a smartphone, a smart card, or the like. To prevent unauthorized operation of the control unit, the control unit can be configured for authentication of the mobile device via wireless communication, such that, with an authorized mobile device, the actuator for operating the second device can be controlled by the control unit.

[0011] Wireless communication between the control unit and the mobile device can be achieved via Bluetooth. This advantageously allows for user-friendly interaction between the user and the control unit using the mobile device, significantly increasing user comfort. Bluetooth communication can be implemented using Bluetooth Low Energy (BTLE) for a particularly energy-efficient approach.

[0012] According to the invention, the adapter comprises a holder for receiving the second device, the holder serving in particular to fix the second device. The second device has, in the usual manner, at least one actuating element, in particular a button, for actuation by the user. According to the invention, the actuator comprises a movable plunger for mechanically actuating the actuating element and an electric motor for moving the plunger, the electric motor being easily operable by the control unit.

[0013] In a functionally reliable yet simple embodiment, the invention provides that the electric motor moves a cam by means of a shaft, with a spring arranged on the plunger for returning the plunger to its restoring position. The cam interacts with the plunger to move the plunger.

[0014] In another, equally reliable and simple embodiment, the plunger can be arranged on a spindle nut. The spindle nut can interact with a threaded spindle to move the plunger. The threaded spindle can then, in turn, be driven by an electric motor.

[0015] Since the second device is typically portable and owned by the user, it is powered by a battery. However, to prevent premature battery depletion when the second device is mounted in the adapter, it can be designed to be powered by the control unit. For this purpose, a battery adapter, electrically connected to the control unit, can be provided to replace the battery in the second device when it is in the mounting bracket. The actuator can also be powered by the control unit.

[0016] To retrofit a standard production vehicle for use in a fleet and / or car-sharing application, the control unit and / or adapter can be designed to be retrofitted. The adapter can then be installed in a suitable location within the vehicle. For this purpose, a housing for the bracket and / or actuator and / or control unit can be provided, ideally in a theft-proof manner. For example, the housing can be located in the glove compartment, engine compartment, or similar location within the vehicle. If the housing is made of plastic, communication with the second device via RF (high frequency) with a range of several meters is possible, and full LF (low frequency) coverage within the vehicle is ensured.If desired, the option to extend communication via NFC (Near Field Communication) is also easily available through an additional module.

[0017] Depending on the desired application, the user's authorization to operate the second device via their mobile device can be limited to vehicle access by opening and closing the vehicle doors and / or driving authorization by starting the vehicle. The vehicle operator can easily transfer a user's authorization to operate the second device via their mobile device to the user's mobile device via mobile network. This then makes the user's mobile device an authorized device.

[0018] The following can be stated regarding a particularly preferred embodiment of the locking system according to the invention.

[0019] To implement universal retrofittable vehicle access and / or retrofittable driving authorization using wireless authorization devices such as a smartphone or smart card, the vehicle's existing locking electronics can be modified, or the original vehicle key can be installed. For solutions using an original vehicle key, the key is disassembled and secured, which requires some effort to electrically control the key circuit board via contacts. The authorization is then transmitted wirelessly between the authorization device and the universal retrofittable vehicle access electronics. The system verifies the validity of the authorization. If valid, the authorized command, in particular opening or closing the vehicle doors, is executed via a wired connection to the disassembled vehicle key.This command is transmitted to the vehicle via the existing interface between the original vehicle key and the vehicle's original access system, where it is then executed by means of the vehicle's locking electronics.

[0020] The invention further enables the use of various original vehicle keys for access and / or driving authorization without requiring disassembly. This is achieved through the use of a remotely controllable, adaptable mechanical vehicle key actuator. As with the solution described above, the authorization is sent to the retrofittable vehicle access and / or driving authorization electronics. If authorization is valid, the corresponding button is mechanically activated, thus executing the command, by means of a suitable, adaptable control of an adaptable actuator and an adaptable fixing of the respective key. The subsequent process is then the same as in the solution described above. For targeted activation or power supply of the key, the battery is replaced by a battery adapter.

[0021] Thus, a remote-controlled, adaptable mechanical vehicle key actuator has been created.

[0022] The advantages achieved with the invention lie particularly in the fact that the vehicle can be used in fleet and / or car-sharing applications in a simple manner. In particular, easy integration into the vehicle is possible, for example, by connecting to the vehicle's overhead control panel (OBD). Nevertheless, both theft protection and protection against misuse of access and / or start authorization are guaranteed. In addition, user data for the locking system can be collected with minimal effort and transmitted in real time and / or in consolidated form to a higher-level system (backend).

[0023] When the adapter according to the invention is used, disassembly of the second device, for example, the vehicle key, is unnecessary. Disassembly itself is complex and carries the risk of damaging the vehicle key, which can lead to unreliable key function. Furthermore, the key circuit board requires complex fixing. Therefore, the vehicle key can often only be installed by the manufacturer of the access solution, which also results in logistical challenges and associated additional costs. Finally, if the retrofitted vehicle access solution is removed, the disassembled key can no longer be used.

[0024] The adapter allows an original key to be installed without disassembling or damaging it. Only the battery needs to be replaced with a battery adapter if necessary. This ensures reliable key functionality at all times. Installation of the key by the user of the access solution is even possible with minimal effort, eliminating the otherwise required logistical effort. Furthermore, after removing the retrofitted vehicle access and / or driving authorization solution, for example, when selling the vehicle, the user can simply replace the battery adapter with a battery to restore the key to its original condition and make it usable again. The key is therefore reusable.The locking system according to the invention therefore offers a simple and quick entry and / or exit of the vehicle, since the key is not disassembled but only inserted into the adapter.

[0025] Exemplary embodiments of the invention with various further developments and configurations are shown in the drawings and are described in more detail below. They show Fig. 1 a motor vehicle equipped with a locking system comprising a first and a second device, Fig. 2 the second mechanism of the locking system in schematic form in top view, Fig. 3 a locking system with retrofittable vehicle access and / or retrofittable driving authorization in a schematic view in a first version, Fig. 4. A locking system with retrofittable vehicle access and / or retrofittable driving authorization in a further version, Fig. 5 the detailed design of the retrofittable vehicle access and / or the retrofittable driving authorization Fig. 4, Fig. 6 a further design of the retrofittable vehicle access and / or the retrofittable driving authorization Fig. 4, Fig. 7 a further design of the locking system according to Fig. 3, Fig. 8 a detailed section from Fig. 7 and Fig. 9 a further development of the retrofittable vehicle access and / or the retrofittable driving authorization Fig. 4.

[0026] In Fig. Figure 1 shows a motor vehicle 1 with the authorized user 2. The motor vehicle 1 is equipped for access authorization with a locking system 3 as a door locking system, which comprises a first device 4 designed as a control unit and an associated second device 5. The in Fig. 2 The second device 5 shown in more detail, which is designed in the form of an electronic key, an identification (ID) transmitter, a chip card, a smart card or the like with a housing 9, is portable and is in the possession of the authorized user 2, who thereby has access to the motor vehicle 1 within a working area 8.

[0027] The first device 4 has at least two states, the first state being a locking state and the second state an unlocking state of the car doors 6. Both devices 4 and 5 have transmitters and / or receivers for transmitting and / or receiving signals 7 via an electromagnetic carrier wave, thus enabling communication between the two devices 4 and 5. At least one of these signals 7 transmitted between the second device 5 and the first device 4 is a coded electromagnetic operating signal. The coded operating signal serves to authenticate the second device 5, so that, if the second device 5 is authorized, a change in the state of the first device 4 can be effected after a positive evaluation of the transmitted operating signal.The transmission of the coded operating signal occurs when the authorized user 2 operates the door handle 16 on the car door 6 or approaches the door handle 16. This triggers the unlocking of the car doors 6 according to the keyless entry functionality. The transmission of the coded operating signal can also occur automatically without the user 2's intervention as soon as they enter the operating area 8, although this will not be discussed further below. If the user closes the car doors 6 from the outside, the car doors 6 lock automatically. The car doors 6 can also lock automatically after the user 2 has left the operating area 8.

[0028] Furthermore, in addition to or as an alternative to the keyless entry functionality, remote locking and / or unlocking of the car doors 6 is also possible to grant user 2 access to the vehicle 1 based on user interaction. This access-based authorization is granted by means of... Fig. Two visible, button-like actuating elements 10 on the housing 9 of the second device 5 can be triggered by the user 2. For example, the central locking system can be locked and / or unlocked, and the trunk lid can be opened, by manually actuating the actuating elements 10, by sending corresponding coded operating signals from the second device 5 to the first device 4. The symbols corresponding to these functions are affixed to the actuating elements 10. Inside the housing 9 is a circuit board 12 on which electronics 46 for the intended operation of the second device 5 are arranged, as shown in the broken-open section of the housing 9 in Figure 1. Fig. 2 is shown. Thus, due to the activation of the operable second device 5 by the user 2 after a positive evaluation of the transmitted operating signal, i.e., with authorized second device 5, a change in the state of the first device 4 can be effected.

[0029] The locking system 3 further establishes the driving authorization for the vehicle 1. For this purpose, the first device 4, designed as a control unit, also causes the ignition lock (electronic ignition lock EZS) and / or the steering lock (electric steering lock ELV) to be unlocked and / or locked according to the two states. Likewise, another functionally relevant component of the vehicle 1 can be controlled accordingly by the first device 4. For example, this can enable and / or disable an immobilizer, the engine control unit, or the like. The transmission of the coded operating signal for authentication of the second device 5 occurs when the authorized user 2 is in the vehicle 1 and manually activates a start / stop switch 11. This triggers the starting process or similar action of the vehicle 1 according to the KeylessGo functionality.The start / stop switch 11 is conveniently located on the gear selector, the ignition lock, in the dashboard, in the center console or the like in the motor vehicle 1.

[0030] For the use of the vehicle 1 in fleet and / or car-sharing applications, it is desirable that the second device 5 does not need to be handed to the respective user 2. It should be sufficient for the user 2 to receive the access and / or driving authorization for the vehicle 1, which may be limited in time or other ways, for example, on a mobile device 13, such as a mobile phone, a smartphone, a smart card, or the like. To grant the access and / or driving authorization, communication 15 then takes place between the mobile device 13 and a control electronics unit 14 located in the vehicle 1 for the authentication of the mobile device 13. After successful authentication, and thus with the authorization of the mobile device 13, the control electronics unit 14 then triggers the state change 45 of the first device 4 for the access and / or driving authorization.

[0031] A first version of such a system is in Fig. Figure 3 shows a more detailed schematic view. For this purpose, the second device 5 is disassembled, and the circuit board 12 comprising the electronics 46 is installed in the motor vehicle 1. The circuit board 12 is electrically connected to the control electronics 14 via control wires 17. With appropriate authorization, the control signals for vehicle access and / or vehicle operation are then transmitted from the control electronics 14 to the circuit board 12 via the control wires 17, so that the electronics 46 are operated as intended to effect access and / or driving authorization and / or other functions of the motor vehicle 1.

[0032] A further embodiment of the first version is in Fig. 7 and Fig. Figure 8 is shown schematically in more detail. Here, the second device 5 is not disassembled. Rather, according to Fig. 7 The entire second device 5 is located in the motor vehicle 1 in a theft-proof arrangement. The control wires 17 connected to the control electronics 14 are led through the housing 9 into the interior of the second device 5 and are electrically connected there to the circuit board 12, as shown in the Fig. 8 can be seen.

[0033] In a further second version, which in Fig. As can be seen in Figure 4, an adapter 18 for accommodating the second device 5 is provided in the motor vehicle 1. The adapter 18 includes a remotely controllable actuator 19 for actuating the second device 5. The adapter 18 is connected to a control unit 14 in the form of control electronics. As already mentioned, the control unit 14 is designed for wireless communication 15 with the mobile device 13 using electromagnetic carrier waves. Specifically, the control unit 14 is designed for authenticating the mobile device 13 using wireless communication 15 in order to verify the authorization of the mobile device 13. If the mobile device 13 is authorized, the actuator 19 can then be actuated by the control unit 14 to actuate the second device 5, whereby the actuation of the second device 5 in turn transmits the corresponding signals 7' for communication between the two devices 4 and 5 (see also Figure 4). Fig. 1) triggers. Wireless communication 15 between the control unit 14 and the mobile device 13 can conveniently be carried out via Bluetooth. This can be communication 15 via Bluetooth Low Energy (BTLE), which is characterized by low energy consumption. Additionally and / or alternatively, this communication 15' can also be carried out via Near Field Communication (NFC), for which an NFC reader 39 is provided for the mobile device 13. The communication 15' then continues via an interface 40 with the control unit 14.

[0034] If the vehicle 1 is used in fleet and / or car-sharing applications, it is advantageous if the authorization for the respective user 2 is transmitted by the operator of the vehicle 1, optionally cryptographically encoded, via mobile network 37 to the mobile device 13 of the user 2, such that the mobile device 13 of the user 2 then becomes an authorized mobile device 13. The management and assignment of the respective authorizations or codes for authenticating the mobile device 13 can be carried out by the operator in a so-called cloud 38, which forms a kind of backend. The authorization of the user 2 to operate the second device 5 using the mobile device 13 can be individually assigned by the operator, for example, to access the vehicle 1 by opening and closing the car doors 6 and / or the trunk of the vehicle 1 and / or to driving authorization by starting the vehicle 1.Naturally, temporal and / or spatial restrictions for user 2 are also possible. In other words, the operator authorizes user 2 to operate the second device 5 in a specific manner and / or to a specific extent using their mobile device 13, in order to trigger the corresponding functions on vehicle 1. Furthermore, the operator can use the mobile device 13 to add or remove vehicle 1 from their fleet.

[0035] What's next in Fig. As shown in Figure 4, anti-theft sensors 41, for example a contact sensor and / or a magnetic sensor, are provided for the vehicle 1, which also cooperate with the control unit 14. Other data for the vehicle 1, for example operating data, are determined by further sensors 42 and collected by an evaluation unit 43. This data can be made available to the operator of the vehicle 1 for further use, for example by forwarding it to the cloud 38. Finally, a power supply 44 from the vehicle 1, for example via the overhead control panel (OBD) in the vehicle 1, is provided to supply the control unit 14, the actuator 19 and, if applicable, the evaluation unit 43 with electrical energy for operation.

[0036] What's next in Fig. As shown in Figure 5, the adapter 18 comprises a holder 20, 21, consisting of a lower and an upper mold half, for receiving the second device 5. The second device 5 is fixed in the holder 20, 21. As already mentioned, the second device 5 has at least one actuating element 10, for example, designed as a button, for actuating the second device 5. The actuator 19 comprises a movable plunger 22 with a spring for mechanically actuating the button 10. Furthermore, the actuator 19 comprises an electric motor 23 for moving the plunger 22, wherein the electric motor 23 can be designed as a DC (direct current) geared motor. The electric motor 23 is arranged on a rail 24 with a grid for mounting the electric motor 23.

[0037] The electric motor 23 moves a cam 26 by means of a shaft 25. The cam 26 interacts with the plunger 22 to move the plunger 22. The spring 27 arranged on the plunger 22 serves to return the plunger 22 to its original position. The shaft 25 is connected to the output shaft of the electric motor 23 by means of a coupling 28 in the form of a shaft-hub connection. On the side facing the electric motor 23, there is a bearing block 29 with a sliding bearing bushing, and on the side opposite the electric motor 23, there is another bearing block 30 with a sliding bearing bushing for supporting the shaft 25. One bearing block 29 is mounted on the rail 24. The other bearing block 30 is mounted on a rail 31 with a detent for securing the bearing block 30. The electric motor 23 can, in turn, be operated by the control unit 14 to actuate the second device 5.The corresponding positions of the cam 26 for actuating the actuating elements 10 of the second device 5 are detected by micro-signal switches (not shown), which in turn are switched by actuators 32 arranged on the shaft 25.

[0038] The second device 5 is usually equipped with a battery for its power supply. However, if the second device 5 is located in the adapter 18, it is advantageous for the second device 5 to be supplied with energy from the control unit 14 in the motor vehicle 1 for its operation. For this purpose, a battery adapter 33, electrically connected to the control unit 14 via a connecting line 34, can be provided to replace the battery in the second device 5 when the second device 5 is located in the holder 20, 21, as shown in Fig. Figure 6 shows that the actuator 19 can also be supplied with energy from the control unit 14 for its operation, for which an electrical connecting line 35 is provided. A corresponding battery adapter 33 with an electrical connecting line 34 to the control unit 14 can, of course, also be provided in the design of the second device 5 with control wires 17, as shown in Figure 6. Fig. 7 is shown.

[0039] As already mentioned, the control unit 14 and / or the adapter 18 can be retrofitted in the motor vehicle 1 in order to make an otherwise unchanged motor vehicle 1 suitable for use in fleet and / or car-sharing applications. A housing 36, which is in Fig. As indicated in Figure 5, the housing 36 is designed to accommodate the bracket 20, 21 and / or the actuator 19. The theft-proof housing 36 can be installed in hard-to-reach locations within the motor vehicle 1.

[0040] For example, the housing 36 can be designed for installation in the glove compartment, engine compartment, or the like of the motor vehicle 1. Furthermore, the housing 36 can be made of plastic so that the transmission of the signals 7' between the second device 5 and the first device 4 is not affected by the housing 36.

[0041] In Fig. Finally, Figure 9 shows a further embodiment of the actuator 19 for actuating the second device 5. The housing 36, which is additionally provided with a protective cover 47, again contains the mounting brackets 20 and 21 of the adapter 18 for the second device 5, the actuator 19, and the control unit 14. The actuator 19 comprises a plunger 22, guided in a guide 56 of the upper mounting bracket 21 and, for example, equipped with a rubber damper, for actuating the actuating element 10 on the second device 5. The plunger 22 is in turn arranged on a spindle nut 48, the spindle nut 48 interacting with a threaded spindle 49, which is, for example, designed as a trapezoidal threaded spindle, to move the plunger 22. The threaded spindle 49 can be driven by an electric motor 23.The electric motor 23, designed as a DC (Direct Current) gear motor, is attached to a circuit board 52 of the control unit 14 by means of a bracket comprising a motor mounting 50 and a steel clamp 51. The connecting cable 34 for the battery adapter 33 (see also . Fig. 6) is contacted on the circuit board 52. Furthermore, a sensor circuit board 53 for mounting sensors and a control board 54 for controlling the electric motors 23 for actuating the second device 5 are located in the housing 36. The control unit 14 has a bus connection to the electronics of the motor vehicle 1, which is secured to the housing 36 or the protective cover 47 by means of a shear guard 55.

[0042] The invention is not limited to the described and illustrated embodiments and configurations. The invention also encompasses all technically refined developments within the scope of the intellectual property claims. Thus, the invention can be used not only for vehicle access and / or for the authorization to drive a motor vehicle, but also for a door lock, for example, on a building or the like, or for other control devices. In particular, it can secure access to a living space and / or an office and / or other authorizations within the office, for example, at a PC (personal computer) workstation.
