Description

State of the art

[0001] The use of mobile security devices, especially locks, to secure vehicles, preferably bicycles, against theft or unauthorized use is well known. Particularly with regard to bicycles, it is common practice for users to carry mobile security devices with them or to keep them on the vehicle, especially the bicycle.

[0002] In particular, high-security locking devices are often heavy and unwieldy, resulting in limited user comfort. Conversely, locking devices with comparatively lower security ratings often offer insufficient protection against theft and are therefore not recommended, especially for securing high-value vehicles. Disclosure of the invention

[0003] The present invention relates to a method for operating a security system, a security system, a computer program product, a computer-readable medium, and a data carrier signal. Further features and details of the invention will become apparent from the dependent claims, the description, and the drawings. Features and details described in connection with the method according to the invention naturally also apply in connection with the security system according to the invention, and / or in connection with the computer program product according to the invention, and / or in connection with the computer-readable medium according to the invention, and / or in connection with the data carrier signal according to the invention, and vice versa, so that the disclosure of the individual aspects of the invention always includes, or allows for, reciprocal reference.

[0004] The present invention serves in particular to enable a safe, reliable and / or convenient securing of a vehicle against theft or against use by unauthorized persons.

[0005] According to a first aspect, the present invention relates to a method for operating a security system for the stationary securing of at least one vehicle. The security system comprises at least one mobile device and at least one, preferably stationary, securing device. The securing device further comprises at least one securing means for securing the vehicle to the securing device and at least one locking device for, at least temporarily, locking the securing means to the securing device. The method comprises: - Establishing a communication link between the security device and the mobile device, in particular via at least one communication interface of the mobile device or the security device, - Exchanging an identifier specific to a backup operation between the backup device and the mobile device, in particular via the communication link, - Releasing a locking mechanism of the locking device in the locking mechanism so that the locking device can be used to secure or unlock the vehicle, in particular by means of the locking mechanism, and - Locking the security device in the locking device, in particular by the locking device.

[0006] In other words, a method for operating a security system is proposed. The security system serves to secure at least one vehicle in a fixed location and comprises at least one mobile device and at least one, in particular stationary, security device.

[0007] The term "stationary" in this context means that the safety device is intended to be fixed to a specific location. In particular, the safety device may be connected to one or more immobile objects. An immobile object could be, for example, a sidewalk or a building. The safety device may, for example, be embedded in concrete, at least in sections, or connected to the immobile object via at least one connection point.

[0008] The securing device comprises at least one securing element for securing the vehicle to the securing device and at least one locking device for, at least temporarily, locking or releasing the securing element to the securing device. Thus, the securing element can be released by the locking device during a locking process, allowing a user to, for example, guide the securing element through a frame of the vehicle to secure the vehicle to the securing device or, after securing, to unlock it again. The securing element can then be locked back into the locking device to complete the locking process. A locking process can serve to secure the vehicle to the locking device or to unlock the vehicle.A securing process can preferably comprise at least two locking processes, namely one locking process to secure and at least one locking process to unlock the vehicle.

[0009] According to the invention, a communication connection, particularly a bidirectional one, is established between the locking device and the mobile device, especially for data exchange. This can preferably be achieved via corresponding communication interfaces of the mobile device or the locking device. Furthermore, it is provided that a specific identifier for a locking operation is exchanged between the locking device and the mobile device, particularly via the communication connection. This means that a corresponding identifier is transmitted from the mobile device to the locking device or vice versa. In particular, it can be provided that the identifier is stored, at least temporarily, in the mobile device and / or the locking device.

[0010] The identifier can be, for example, a numeric, alphabetic, or alphanumeric identifier. The identifier allows for the unique identification of a securing process when a vehicle is locked to the locking device. After the vehicle has been secured, it also allows verification of whether a user is authorized to unlock the vehicle. Specifically, after a vehicle has been locked to the locking device, only the person in possession of the identifier specific to that securing process is authorized to unlock the vehicle. The identifier can be transmitted in encrypted form. A locking-specific identifier can be generated by the locking device and transmitted to the mobile device, or conversely, generated by the mobile device, stored by it, and / or transmitted to the locking device.

[0011] Preferably, when a vehicle is secured at the locking device, the identifier is generated by the locking device and transmitted to the mobile device. If a user wishes to unlock a vehicle after it has been previously locked, it is preferred that the identifier is transmitted from the mobile device to the locking device. In particular, the identifier transmitted by the mobile device can then be compared with the identifier stored in the locking device to verify whether the user is authorized to unlock the vehicle. The user is specifically the owner of the mobile device.

[0012] Furthermore, the present invention provides that the locking mechanism of the locking device is released. The locking device can then be used by a user to secure a vehicle to the locking device. For example, the locking device can be guided through a frame of the vehicle so that, after the locking device is re-engaged in the locking device, the vehicle can no longer be removed, or substantially no longer be removed, from the locking device. If the vehicle was already secured to the locking device, the locking device can, for example, be guided back through the frame to unlock the vehicle and subsequently remove it from the locking device.

[0013] Furthermore, the locking device is designed to be re-engaged in the locking mechanism, either to secure the vehicle to the locking device or to complete the unlocking of the vehicle. If the locking device is unlocked, it can then be used again to secure a vehicle.

[0014] The inventive method for operating a locking device for the stationary securing of at least one vehicle offers the advantage that a vehicle can be reliably secured against theft or unauthorized use without the vehicle's user having to carry a mobile locking device, in particular a lock. Furthermore, performing a locking operation using a mobile device allows for a particularly high level of user convenience.

[0015] It may be intended that at least individual steps of the procedure are performed repeatedly. Furthermore, it is conceivable that the individual steps are performed in the specified order.

[0016] In relation to the present invention, it may be provided that the communication link between the mobile device and the locking device is designed as an NFC (Near Field Communication) connection, wherein the exchange of the user-specific identifier, at least or only with regard to unlocking a vehicle, comprises the following: - Transferring activation energy to perform a transmission process from the backup device to the mobile device.

[0017] In other words, it can be provided that the identifier specific for the security process is exchanged between the mobile device and the security device via an NFC connection. A communication interface of the security device can preferably be configured as an active NFC interface, through which activation energy for carrying out a transmission process can be transferred to the mobile device, particularly inductively. The mobile device can then use the transferred energy to carry out the transmission process.

[0018] This offers the advantage that a user can unlock the vehicle even if the mobile device's energy storage device, particularly its battery, is depleted and the mobile device alone is unable to perform the transmission process. The transmission process can, in particular, be a transmission of the identifier specific to the locking process, especially from the mobile device to the locking device. Such a procedure has proven particularly advantageous for unlocking a vehicle after it has been previously locked to the locking device, where, specifically during the locking process, the identifier was transmitted to and stored on the mobile device.

[0019] It may also be advantageous with regard to the present invention if the method further comprises at least the following: - Applying an electric current to the safety device when the safety device is locked in the locking mechanism, - Monitoring the current flow in the fuse, in particular by means of at least one current sensor, and optionally - Activate at least one alarm device if a sufficient change, in particular interruption, of the current flow has been detected.

[0020] This approach offers the advantage that any tampering with the security device, for example during an attempted theft of a vehicle secured to the device, can be reliably detected and an alarm triggered. Monitoring the current flow can include, in particular, comparing the current flow, especially as detected by the current sensor, with a target value or limit value.

[0021] With regard to the present invention, it may be advantageously provided that the security system comprises at least one vehicle, wherein the vehicle comprises at least one alarm means, and that in particular the method further comprises: - Establishing a communication link between the locking device and the vehicle, in particular via at least one communication interface of the vehicle or the locking device, - Transmitting a signal to activate at least one alarm device of the vehicle from the security device to the vehicle, in particular via the communication link, and - Activation of the alarm system by the vehicle.

[0022] In this context, activation of the alarm device shall be understood to mean that the alarm device emits at least one alarm signal, in particular an acoustic and / or visual warning signal.

[0023] Additionally or alternatively, it is conceivable that the security system comprises at least one vehicle, wherein the vehicle comprises at least one tracking device and, in particular, the method further comprises: - Establishing a communication link between the locking device and the vehicle, in particular via at least one communication interface of the vehicle or the locking device, - Transmitting a signal to activate at least one tracking device of the vehicle from the security device to the vehicle, in particular via the communication link, and - Activation of the tracking device by the vehicle.

[0024] In this context, it is conceivable that the signal to activate at least one alarm device and / or the signal to activate at least one tracking device from the security device to the vehicle is only transmitted when a sufficient change, in particular an interruption, in the current flow at the security device's locking element has been detected. In other words, an alarm device and / or tracking device on the vehicle can be activated if tampering with the locking element has been detected.

[0025] At least one alarm device can be designed to emit at least one warning signal, in particular an acoustic and / or visual signal. For example, at least one alarm device can include at least one light source, in particular an activatable one, to generate a visual alarm signal. Additionally or alternatively, at least one alarm device can include at least one loudspeaker to generate an acoustic alarm signal. An alarm device, when activated, can alert persons in the vicinity to unauthorized activity on the security device or the vehicle.

[0026] At least one tracking device can preferably be a position transmitter, in particular a GPS transmitter or GPS tracker (GPS, Global Positioning System). This allows a user, for example using a mobile device, to track the vehicle's position and locate a potentially stolen vehicle. Instead of GPS, other global navigation systems such as GLONASS, Galileo, or Beidou can also be used in a similar manner.

[0027] With regard to the present invention, it is additionally or alternatively conceivable that the safety system comprises at least one vehicle, the vehicle comprising at least one blocking device for, at least temporarily, blocking a drive train of the vehicle, wherein the method further comprises: - Establishing a communication link between the locking device and the vehicle, in particular via at least one communication interface of the locking device or the vehicle, - Transmitting a signal to lock or unlock the vehicle's drivetrain from the locking device to the vehicle, in particular via the communication link, and - Blocking or releasing the drivetrain by the blocking device.

[0028] A locking device is understood to be a device designed to block the vehicle's drivetrain in such a way that the vehicle can no longer be moved as intended while the device is engaged. For example, the drivetrain of a bicycle can be blocked in such a way that the crank mechanism, which is connected to the pedals and intended for propulsion, can no longer be turned.

[0029] A drivetrain can be locked in place by various means. For example, at least one rotatably mounted component, such as a gear or similar, can be locked in a fixed position, at least temporarily or substantially, by the locking device. Similarly, different drive elements of the drivetrain, such as the crankshaft and chain of a bicycle, can be decoupled from each other, at least temporarily, by the locking device, so that a connection necessary for propulsion of the vehicle can be broken or is broken by the locking device.

[0030] Additionally or alternatively, the safety system may include at least one vehicle, the vehicle comprising at least one blocking device for, at least temporarily, blocking a drive train of the vehicle, the method further comprising: - Establishing a communication link between the mobile device and the vehicle, in particular via at least one communication interface of the mobile device or the vehicle, - Detecting a breakdown in the communication link between the mobile device and the vehicle by the vehicle and - Blocking or releasing the drivetrain by the blocking device.

[0031] The interruption of the communication connection can be caused, in particular, by a user moving away from the vehicle with their mobile device. In this case, the vehicle's drivetrain can be blocked by the immobilizer to further secure the vehicle against unauthorized use.

[0032] Preferably, the communication link between the safety device and the vehicle and / or the mobile device and the vehicle can be a Bluetooth connection, particularly preferably a BLE connection (BLE, Bluetooth Low Energy). This allows for particularly energy-efficient signal transmission.

[0033] An advantageous further development of a method according to the invention may consist in the fact that at least the following is also included: - Transmitting status information from the security device to the mobile device, wherein the status information is characteristic of at least one of the following: ◯ A power supply state of the safety device, ◯ an occupancy history of the safety device and / or ◯ an alarm history of the security device.

[0034] This approach allows for simple and reliable reading of the status of a backup device. In particular, the backup device does not need to actively transmit the status information to a higher-level system. This eliminates the need for expensive communication interfaces for remote transmission on the backup device side. Instead, the mobile device serves as a transmission aid for sending the status information to a central instance. Specifically, it can be configured that the status information is then transmitted from the mobile device to a central server.

[0035] An energy supply state is preferably characteristic of the charge level of at least one energy storage device of the security system. An occupancy history is preferably characteristic of security operations or locking operations carried out on the locking system in the past, particularly within a specific period. An alarm history is preferably characteristic of activations of at least one alarm device on the security system in the past, particularly within a specific period.

[0036] Additionally or alternatively, the present invention may provide that the security system comprises at least one further mobile device and that the method further comprises: - Establishing a communication link between the mobile device and the other mobile device, in particular via communication interfaces of the mobile devices, and - Transferring the identifier specific for the backup process from the mobile device to the other mobile device, in particular via the communication link.

[0037] This approach allows the authorization to unlock a vehicle at the locking device to be transferred from one mobile device to another. This results in increased user-friendliness of the locking system. For example, a vehicle can be locked at the locking device by one user and thus made available to a second user. The first user can then transfer the unique identifier used for the locking process to the second user's mobile device, granting them the authorization to unlock the vehicle and thus use it. It is preferable that the communication link between the two mobile devices be a cellular connection.

[0038] According to a second aspect, the present invention relates to a security system for the stationary securing of at least one vehicle. The security system comprises at least one mobile device and at least one, in particular stationary, securing device. The securing device, in turn, comprises at least one securing means for securing the vehicle to the securing device and at least one locking device for, at least temporarily, locking the securing means to the securing device. In particular, it can be provided that the security system is configured to be operated according to a method according to the invention, in particular according to one of claims 1 to 9. With regard to a security system according to the invention, the same advantages arise as those already described with regard to a method according to the invention.

[0039] At least one vehicle may be designed as a bicycle, in particular an electrically powered bicycle, preferably a pedelec. Additionally or alternatively, at least one vehicle may be designed as a scooter, in particular a kick scooter, motor scooter, or e-scooter. At least one vehicle may be, at least partially, electrically powered.

[0040] Additionally or alternatively, the method or security system can be used for the stationary securing of other objects, in particular a piece of luggage, especially a suitcase or bag, and / or a piece of sports equipment, especially at least one ski or snowboard.

[0041] At least one securing device may preferably be designed as a chain or a steel cable. In particular, the use of a steel cable has proven to be especially advantageous with regard to the present invention.

[0042] At least one safety device can be encased, at least partially, in a protective sheath. This sheath can preferably be made of plastic. This protects the safety device from the elements and increases its service life.

[0043] Additionally or alternatively, it may be provided that, in at least one locking device, a first end of the locking device is permanently, in particular irremovably, connected to the locking device, and a second end of the locking device can be locked in the locking device, at least temporarily. The terms "permanently" and "irremovably" refer here to the intended use of the locking device, such that, within the scope of this use, particularly during a locking or locking operation, it is not possible to detach or release the first end of the locking device from the locking device, especially by a user, particularly without causing damage.

[0044] The safety system, in particular the safety device, may preferably comprise at least one control unit, wherein the control unit is particularly configured to control the safety system according to a method according to the invention or to execute at least individual steps of a method according to the invention. For this purpose, the control unit may be in signal communication with, or be able to communicate with, at least temporarily with, at least one component of the safety system, in particular at least one communication interface, at least one current sensor and / or at least one alarm device and / or at least one tracking device and / or further components of the safety system.

[0045] At least one control unit may preferably include data processing means. The data processing means may preferably include at least one processor, at least one main memory, and / or at least one data storage device, in particular a non-volatile one.

[0046] At least one safety device may preferably include at least one energy storage device for supplying energy to the safety device. The use of an energy storage device avoids the need to connect the safety device to existing infrastructure, such as a power grid. Additionally or alternatively, however, at least one safety device may also include a grid connection for connection to a power line, particularly one connected to the power grid.

[0047] At least one mobile device and / or at least one safety device and / or at least one vehicle may preferably include or have at least one communication interface for establishing a communication connection. At least one communication interface may preferably be configured as an NFC interface and / or Bluetooth interface, in particular a BLE interface, and / or a mobile communication interface.

[0048] With regard to the present invention, it may further be provided that the locking device and / or at least one vehicle comprises at least one alarm means for generating a visual and / or acoustic alarm signal.

[0049] At least one mobile device may be particularly preferably designed as a smartphone or a tablet with regard to the present invention.

[0050] According to a third aspect, the present invention relates to a computer program product comprising instructions that cause a security system according to the invention, in particular a security system according to one of claims 10-12, to execute a method according to the invention, in particular a method according to one of claims 1-9. With respect to a computer program product according to the invention, the same advantages arise as those already described with respect to a method and / or a security system according to the invention.

[0051] According to a fourth aspect, the present invention relates to a computer-readable medium, in particular a storage medium, wherein a computer program product according to the invention, in particular a computer program product according to claim 13, is stored on the computer-readable medium. With respect to a computer-readable medium according to the invention, the same advantages thus arise as those already described with respect to a method and / or a security system and / or a computer program product according to the invention.

[0052] According to a fifth aspect, the present invention relates to a data carrier signal by which a computer program product according to the invention, in particular a computer program product according to claim 13, is transmitted. With respect to a data carrier signal according to the invention, the same advantages thus arise as those already described with respect to a method and / or a security system and / or a computer program product and / or a computer-readable medium according to the invention.

[0053] The present invention further relates to a method for operating a security system for the stationary securing of at least one vehicle, comprising at least one mobile device and at least one stationary storage device for storing at least one mobile security device in a storage room, wherein the storage device comprises at least one release device, in particular a lock, by which access to the storage room can be released or blocked, the method comprising: - Establishing a communication link between the storage device and the mobile device, in particular via at least one communication interface of the mobile device or the storage device. - Exchanging an identifier specific to a backup operation between the storage device and the mobile device, in particular via the communication link, - Releasing access to the storage room via the release device and optionally - Blocking access to the storage room by the release device.

[0054] The proposed method provides a user with access to a mobile security device, in particular a mobile bicycle lock, which enables them to secure a vehicle against theft and unauthorized use.

[0055] The procedure may also include: - Establishing a communication link between a mobile security device and the mobile device, in particular via at least one communication interface of the mobile device or the security device, - Exchanging an identifier specific to a backup operation between the backup device and the mobile device, in particular via the communication link, - Releasing a locking mechanism of a locking device, in particular by a locking device, so that the locking device can be used to secure or unlock the vehicle, in particular by the locking device, and - Locking the locking device in the locking device, in particular by means of a locking device.

[0056] The present invention further relates to a security system for the stationary securing of at least one vehicle, comprising at least one mobile device and at least one stationary storage device for storing at least one mobile security device in a storage space, wherein the storage device includes at least one release device, in particular a lock, by which access to the storage space can be granted or blocked. In particular, the security system is designed to be operated according to a method according to the invention. Furthermore, the security system can comprise at least one mobile security device, wherein the security device is preferably arrangable in the storage space.

[0057] At least one safety device can be designed such that releasing and / or locking a safety element is electromechanically feasible. At least one safety device can comprise at least one energy storage device, in particular at least one battery or at least one accumulator.

[0058] It may be provided that at least one power supply connection for charging at least one energy storage device or at least one mobile security device is arranged or designed in the storage room.

[0059] It may be provided that at least one mobile security device is locked or lockable in the storage device and can be unlocked at the station via a smartphone app using Bluetooth, NFC or RFID.

[0060] Preferably, the communication link between the storage device and the mobile device ends when a mobile security device is removed from the storage space.

[0061] The mobile security device only switches to the active state when it is removed, in which state it can be used by a user.

[0062] Now a communication connection, in particular a Bluetooth connection or BLE connection, is established from the mobile security device to the mobile device.

[0063] The mobile security device can now be optionally locked via the mobile device using facial recognition, fingerprint, a numerical code, or the vehicle's identification number after it has been attached or the vehicle has been secured. It can then be unlocked again after use. The usage period ends when the mobile security device is returned to its storage location.

[0064] The option of a fingerprint sensor on the locking device allows the user to unlock the bicycle directly at the locking device, even if the mobile device's battery is empty.
