Description

Vehicle lock and method for access-controlled loading and / or unloading

description

The invention relates to a vehicle lock with a locking mechanism comprising a catch and a pawl for locking the catch and a method for an access-controlled loading and / or unloading of a vehicle.

For some years, the automation of the transportation of goods and consignments has been increasing rapidly. With large online mail order companies, logistics and parcel service providers, a high level of automation for the handling, movement and tracking of each individual consignment is usually already to be observed, whereby automation is being pushed further and further in these areas in order to achieve savings potential. However, an increasing automation of goods movements is also predicted for previously non-automated processes of the ordinary private household, for example, a self-refillable refrigerator or the like.

The transport of goods and consignments, which may also be referred to as cargo in a simplified manner, is generally carried out by means of vehicles, usually with a cargo bed or trunk used to store the cargo for the purpose of transport. An access door or access door provides access to the cargo bed or trunk for loading and / or unloading the cargo. It is also basically conceivable that the access door or access door allows access to a loading space of the vehicle, which is present in addition to the loading area or the trunk. The goods and consignments that can be loaded into the vehicle are generally ordered and intended for safekeeping, such as clothing, electronic devices or foodstuffs intended for storage, but may also be for immediate consumption certain foods or mail items in the Vehicle to be loaded or unloaded from this. The access door or access door is normally secured by a lock with a catch and pawl against unwanted opening while driving or against access by an unauthorized person.

It is an object of the invention to provide a further developed vehicle lock, which allows an increased degree of automation when loading a vehicle. In particular, the further developed vehicle lock enables simple use of the vehicle in which the vehicle lock is installed, as a delivery address for goods and consignments.

To achieve the object serve a vehicle lock with the features of the main claim and a method with the features of the independent claim. Advantageous embodiments will be apparent from the dependent claims.

The abovementioned features known from the prior art can be combined individually or in any desired combination with one of the objects according to the invention described below. The object is achieved by a vehicle lock comprising a ratchet with a rotary latch and a pawl for locking the rotary latch in a closed state of the vehicle lock, a receiving device for receiving a reference code for a loading and / or unloading, a code transfer interface for obtaining an access code and a Control unit configured such that when the obtained access code is equal to the reference code, the vehicle lock assumes an unlocked state. The receiving device is preferably enclosed by a housing of the vehicle lock or connected directly to the housing. By "directly connected to the housing" is to be understood in this context that the receiving unit is spatially arranged in close proximity to the housing of the vehicle lock and connected thereto via connecting means, for example screwed with screws as connecting means to the vehicle lock Connection with the housing can be used for example for retrofitting an existing vehicle lock with a receiving unit. In an alternative embodiment, the receiving unit may be spatially separated from the vehicle lock, for example, integrated into a vehicle electronics and connected to the vehicle lock via a data line.

In a vehicle lock, there is usually a closed state, an open state, a locked state and / or an unlocked state. In the closed state of the vehicle lock, the catch has received a locking pin and is held by the pawl in a detent position, for example, a main detent position or pre-detent position, so that a vehicle door or vehicle door located in a closed position with the vehicle lock while driving can not open unplanned ,

If the pawl is triggered so that the pawl no longer holds the catch in the locked position and the catch consequently releases the latch again, the vehicle lock has taken the open state. The vehicle door or vehicle door is then no longer held by the vehicle lock in the closed position, but can take an open position.

If the vehicle lock is in the closed state and at the same time in the unlocked state, the vehicle lock can be brought into the open state for opening the vehicle door or vehicle flap, for example by an automatic opening device or a manual actuation of an inner or outer actuating lever.

If the vehicle lock is in the closed state and at the same time in the locked state, the vehicle lock can not be brought into the open state until the vehicle lock has been transferred to the unlocked state. A receiving device for receiving a reference code for a loading and / or unloading process is usually an electronic device which can receive and preferably also process a signal which contains a reference code so that the reference code can be forwarded to the control unit. Alternatively, a receiving device may also be a manual input device or external data interface such as a USB port. In the present case, however, the receiving device is preferably configured such that the receiving device can receive a signal in the form of electromagnetic radiation in a predefined frequency range and, in particular, also convert it into a digital signal. In particular, the receiving device is connected to the control unit via a data line.

Reference code and / or access code mean a multidigit, binary or digital code, in particular having at least 4, preferably 6, more preferably 8 digits or bytes, eg "1234." In this context, a "reference code for loading" means a reference code which is provided for this purpose to allow an opening of the vehicle lock to be able to load the corresponding vehicle. In this context, a "reference code for discharging" means a reference code which is provided to allow an opening of the vehicle lock in order to be able to unload the corresponding vehicle, for example, a discharge of the vehicle by a person other than a driver of the vehicle In order to return a consignment or to use the vehicle as a pick-up address for deliveries other than a driver of the vehicle, it may also be provided that a reference code for a combined loading and unloading operation is provided in which one or more shipments into the Vehicle and one or more other consignments are taken out of the vehicle The reference codes are intended to be used by someone other than the driver of the vehicle.

A code transfer interface for obtaining an access code is usually an electronic device which can receive and preferably also process a signal containing an access code in order that the access code to the Control unit can be passed. Alternatively, a code transfer interface may also be a manual input device or external data interface such as a USB port. In the present case, however, the code transfer interface is preferably configured so that the code transfer interface can receive a signal in the form of electromagnetic radiation in a predefined frequency range and, in particular, also convert it into a digital signal. In particular, the code transfer interface is connected to the control unit via a data line.

Received access code means the code the code transfer interface has received. For example, if an access code is erroneously transferred, the obtained access code is not equal to the access code that has been transferred to the code transfer interface. The example of a manual code entry would correspond to a typing error in the code entry.

A control unit is usually an electronic device with a processor and a memory. In particular, the control unit may include means such as e.g. loadable program code or a computer program product with a loadable program code section, in order to process method steps when the means is executed in a microprocessor-based component. A corresponding software program product is a separate aspect of the invention.

A method step which can be executed by the control unit comprises the comparison as to whether the obtained access code is equal to the reference code. If this comparison results in a match, the vehicle lock is caused to assume an unlocked state.

The control unit, which is configured such that when the obtained access code is equal to the reference code, the vehicle lock assumes an unlocked state, so sends in accordance with the access code with the reference code, a signal for unlocking the vehicle lock. The receiver of this signal is in particular a locking control device, eg the Central locking system, the DCU (Door Control Unit) or the ECU (Electronic Control Unit) of the vehicle.

The vehicle door or vehicle door, which preferably leads to the loading area or the trunk, can then be opened for example by an automatic opening device or manual actuation of an actuating lever for loading.

A vehicle lock comprising a ratchet with a rotary latch and a pawl for locking the rotary latch in a closed state of the vehicle lock, receiving means for receiving a reference code, a code transfer interface for obtaining an access code and a control unit configured such that when the obtained access code is equal to the reference code, the vehicle lock assumes an unlocked state, an access-controlled loading of a vehicle is made possible with a particularly high degree of automation, but requires very little or no adjustments to the other vehicle components. The access-controlled loading of the vehicle can consequently be offered as an optional and / or retrofittable equipment variant. Furthermore, no additional space is required for complex installations for access control, so that a particularly compact solution can be obtained by the vehicle lock according to the invention. Loading is thus controlled access both for messengers, so persons, as well as robots or drones allows. Thus, for example, in a supermarket, an employee may already load the purchases of a buyer into the buyer's vehicle after the reference code has been sent from the supermarket to the vehicle lock. The buyer no longer needs to hand over his vehicle key to the employee. Abuse can be prevented in this way.

By mail order or by parcel service providers, for example, the reference code may be sent from a cargo dispensing station to a delivery vehicle provided for delivery of a shipment. The charge can then transferred to a load carrier to transport the cargo from the cargo delivery station to said delivery vehicle, load it there and return to the cargo delivery station. The delivery vehicles can remain securely closed in this way, so that theft can be prevented.

By cargo is meant generally a consignment, a package or a commodity which is to be loaded into a vehicle for the purpose of transport.

By load transporter is generally meant a person or device for transporting a load to a vehicle and loading the cargo into the vehicle, e.g. a robot or a drone. In one embodiment, the receiving device is designed such that the reference code can be sent to the receiving device without contact and / or from a distance of at least 100 m, preferably 1000 m, particularly preferably 10000 m. A charge-dispensing station may thereby send reference codes to a particularly wide variety of vehicles. In addition, as an alternative to the charge output station, the transmission of the reference codes can be carried out by an external transmitting station. In one embodiment, the receiving device comprises a SIM card receiving unit for a SIM card or eSIM and / or a mobile radio unit.

SIM (subscriber identity module) is a smart card that is commonly used in mobile phones. eSIM (embedded SIM) is a fixed smart card that can not be exchanged, but as a rule the eSIM is assigned to a SIM card. A mobile radio unit serves to receive and in principle also transmit a mobile radio signal in the frequency range of electromagnetic radiation intended for mobile radio communication. In particular, the mobile radio unit is set up as M2M (Machine to Machine) in order to ensure a particularly reliable and direct transmission of the reference code from a transmitting unit to the receiving device.

A receiving device with a SIM card receiving unit for a SIM card or eSIM and / or a mobile radio unit allows a particularly reliable transmission of the reference code to the vehicle lock and a particularly simple management of multiple vehicles with a vehicle lock according to the invention at the charge output station.

In one embodiment, the code transfer interface is such that the access code can be transmitted to the code transfer interface in a non-contact manner.

The vehicle lock is usually arranged with the exception of the external actuating lever within the vehicle, ie within the outer outer surface of the vehicle, and is visible and accessible only after opening the vehicle door or flap. Entering an access code, such as via an input device, would therefore require an additional, external component that would need to be weatherproof and attached to the outside of the vehicle. This would be very expensive. The contactless transmission of the access code to the code transfer interface makes it possible for the access code to be obtained and processed by the control unit of the vehicle lock itself, without first having to open the vehicle door or flap or to provide additional external components. In one embodiment, the code transfer interface is such that the access code can only be transmitted to the code transfer interface within a distance of less than 100 m, preferably less than 10 m, particularly preferably less than 1 m, to the vehicle lock. This allows the use of non-contact data communication techniques, which are inexpensive and very easy to use. Furthermore, it is avoided that, for example, when providing an automatic opening device, the vehicle door or flap already opens prematurely when the loading conveyor is not even in sight of the vehicle.

In particular, an access code unit of the load carrier serves to transfer the access code to the code transfer interface.

In one embodiment, the code transfer interface is an NFC (Near Field Communication) interface, an RFID (Radio Frequency Identification) interface, a Bluetooth interface, and / or a WLAN (Wireless Local Area Network) interface Wireless Local Area Network).

A robot or a drone can thus very easily gain access to the loading area or the trunk of the vehicle. Also, a person who usually carries the cargo in both hands, thus does not need to first deposit the cargo to enter the access code.

An NFC interface is in particular a receiving module which can receive data by electromagnetic induction, preferably by means of loosely coupled coils, basically over a short distance of for example a few centimeters, ie less than 10 cm, which is based on the RFID technology international transmission standard for contactless exchange uses data and / or which achieves a data transfer rate of a maximum of 424 kBit / s. An RFID interface is in particular an RFID reader for an RFID tag as the access code unit of the loading transporter, also called RFID transponder. The structure of an RFID transponder sees in particular an antenna, an analogue circuit for receiving and transmitting (transceiver) and / or a digital circuit and a memory for storing the access code, for example. The digital circuit may be a microcontroller. As a rule, RFID transponders have at least one write-on memory, which preferably contains the access code temporarily or permanently.

In particular, the RFID transponder is an active RFID tag with its own power supply or a passive RFID tag, which uses the radio frequency energy absorbed by it during the communication process as a power supply. But even a semi-active RFID tag is feasible, in which a battery only covers the supply of a portion of the power demand.

In particular, the microchip in the RFID tag decodes the commands sent by the RFID reader and encodes and / or modulates the response, ie the access code, into the radiated electromagnetic field by weakening the field in contactless short circuit or reverse phase reflection of the field emitted by the RFID reader. The RFID tag itself does not generate a field, but influences the electromagnetic transmission field of the RFID reader.

A particularly easy for the load carrier transferring the access code can thus made possible and transmission errors can be avoided.

A Bluetooth interface and / or a WLAN interface allow the use of smartphones or portable tablet PCs to enable a controlled loading.

In particular, the access code unit of the loading transporter is therefore an RFID tag or N FC tag or a smartphone or tablet PC equipped with a Bluetooth interface and / or WLAN interface. In one embodiment, the control unit is configured such that when the obtained access code is equal to the reference code, the control unit sends a signal for shutting off a cargo area or a trunk. Shut-off of a loading area or of a luggage compartment can be effected, for example, by blocking a rear seat bench, for example by a microdrive and / or by raising and / or securing headrests for the rear seat bench. Thus, after the load transferor gains access to the cargo bed or trunk, the load handler can not advance further into the vehicle cab. A possible misuse and theft of items from the vehicle cab can be prevented. In one embodiment, the control unit is configured such that when the obtained access code is equal to the reference code, the control unit sends a signal to automatically open a vehicle door or door to an opening device. In particular, the vehicle door or flap serves to open and close access to a cargo bed or a trunk. In an alternative embodiment, a separate loading box, in particular with a separate vehicle door or flap, may be provided for loading, unloading and storing the load during transportation with the vehicle.

A robot or a drone can thus very simply transport the load onto the loading area or into the trunk. Even a person who usually carries the cargo in both hands, thus does not need the first drop off the load to open the vehicle door or flap.

In particular, the shut-off of the loading area or of the boot takes place before transferring the vehicle lock into the unlocked state and / or before sending the signal for automatic opening to the opening device. In one embodiment, the control unit is configured such that after a successful load, the control unit sends a signal for automatically closing the vehicle door or flap to a locking device. In particular, the opening device and the closing device are one and the same opening and closing device, which is preferably operated electrically. After loading has taken place, it is the time when the load is in the vehicle and the load carrier is completely outside the vehicle.

This time can be determined, for example, by a fixed time value based on empirical values. Alternatively, a signal for determining the completion of the charging process to the receiving device, the code transfer interface or another interface of the vehicle lock, such as a button, are transmitted. In particular, the termination of the communication link to the load conveyor is used as an event to send the signal to automatically close the vehicle door or door to a locking device.

A robot or a drone then need not be equipped with additional functionalities to close the vehicle door or flap mechanically and also forgetting the closing of the vehicle door or flap by a person as a load conveyor can be avoided.

In one embodiment, the control unit is configured such that, when the vehicle lock is brought to an open state and then to the closed state after the release of the unlocked state, the vehicle lock assumes a locked state, that is, the control unit a signal for locking the vehicle lock to the Interlock control device sends.

After the loading has taken place and the vehicle door or flap has been closed, ie the vehicle lock has been brought into the closed state, is thus automatically locked to prevent unauthorized access. In one embodiment, the control unit is configured such that the control unit resets the reference code after a predefined period of time, eg, one hour) and / or after taking the unlocked state as a result of matching the obtained access code with the reference code. Reset means delete, reset to zero or reset to a predefined value.

Abuse and unwanted access to the vehicle using the access code for purposes other than the intended loading of the cargo can thus be counteracted.

In particular, the control unit may also reset the reference code, preferably immediately after the control unit has sent the vehicle lock locking signal to the lock control device when, after taking the unlocked state, the vehicle lock has been brought into an open state and then into the closed state. In one embodiment, the vehicle lock comprises a charge input control device, in particular a charge ID scanner, and / or a load monitoring device, in particular a camera.

The charge input control device can ensure that even the right load is loaded into the vehicle. For this purpose, a

Charge ID scanner, e.g. a bar code scanner to be installed in the vehicle lock, in particular on the lock case or in the area of the lock case.

A load with a barcode can thus be identified with particular reliability.

Alternatively, a weight determining device may be provided for determining the weight of the load and comparing this weight with a predetermined weight range to identify the load. By the load monitoring device, a proper charging can be monitored. For this purpose, a camera can be installed in the vehicle lock, in particular on the lock case or in the area of the lock case. For example, via the mobile radio connection of the receiving device, the loading process can be visually monitored from the charge delivery station or alternatively a separate monitoring station. The monitoring can take place live, ie in real time, or in the form of security records. Optionally, a microphone may be provided to allow the load carrier to deliver a voice message to the cargo delivery station or to talk through the speaker to the charge delivery station. In particular, the load monitoring device can also be used as a charge input control device to save additional facilities. For example, a scan of a charge ID, such as a barcode, can in principle also be used with a camera as load monitoring device.

In one embodiment, the vehicle lock comprises a display device, in particular LED, and / or a loudspeaker, wherein the display device and / or the loudspeaker are preferably integrated in a lock case of the vehicle lock.

By the display device, which can be implemented as a particularly space-saving as LEDs, and / or the speaker, it is possible to ask an employee as a load transporter to scan the load and display the result of the goods receipt control or output as an audible signal. Because the scanner should only be activated as short as possible to save resources. This is particularly important if the scanner itself is used to identify the scanner area and / or to illuminate the area to be scanned. The speaker can also provide predefined commands such as "Scan Now, Thank You".

In addition, a loudspeaker allows live communication between the loading conveyor and the cargo dispensing station, transmitting station and / or monitoring station.

In one embodiment, acknowledgment information for acknowledging the successful loading of a particular load into a particular vehicle may be communicated via the receiver to the cargo dispensing station or via the code transfer interface to the access code unit of the load carrier where that information is stored.

In one embodiment, a lighting means may be provided which is preferably integrated in or disposed on the lock case. Particularly reliable scanning of a charge ID, e.g. Barcode, especially when using the camera and / or a particularly effective monitoring by a camera, especially in otherwise dark environment can be made possible. In addition, the illumination means can be used to identify the scanner area, so that the charge ID can be positioned accordingly.

A further aspect of the invention relates to a method for access-controlled loading and / or unloading of a vehicle by means of a vehicle lock, in particular according to one of the preceding embodiments of the vehicle lock according to the invention, with a rotary latch and a pawl for locking the rotary latch in a closed state of the vehicle lock a reference code for unloading and / or loading is received by a receiving device of the vehicle lock, an access code is obtained from a code transfer interface of the vehicle lock and a control unit of the vehicle lock transfers the vehicle lock to an unlocked state if the obtained access code is equal to the reference code. A particularly highly automated access-controlled loading a vehicle can be enabled. The above-described embodiments and examples as well as definitions may also be applied to the method. In one embodiment of the method, it is provided that first a charge dispensing station sends the reference code to the receiving device, transfers an identical with the reference code access code to a loading conveyor, so verbally communicates and / or plays on an access code unit of the loading transporter, and a charge to the Loading transporter, which is intended to be loaded into a particular vehicle, and then the load carrier transports the load to the vehicle, wherein the access code is transferred to the code transfer interface when reaching the vehicle, either by manual input or non-contact eg using the access code unit, and upon agreement of the obtained access code and the reference code, the vehicle door or vehicle door is unlocked and can be opened for loading the cargo.

Embodiments of the invention will be explained in more detail with reference to figures. Features of the embodiments may be combined individually or in a plurality with the claimed subject matter.

FIG. 1 shows an exemplary vehicle lock according to the invention.

Figure 2: Schematic representation of a control device of a

exemplary vehicle lock according to the invention with associated facilities.

Schematic representation of the procedure for access-controlled

Loading and / or unloading a vehicle using the vehicle lock according to the invention. Figure 1 shows an exemplary vehicle lock according to the invention, in which the catch 1 and the pawl 2, which is hidden in Fig. 1 of the lock case 15 and is therefore only indicated by dashed lines, in particular together with a release lever, not shown on a lock plate or a Lock case 15 comprising the lock plate are rotatably mounted. The lock case 15 is preferably made of metal and is usually attached to the vehicle body with screws.

The lock case 15 has an inlet slot 21 for receiving a locking bolt 14. A locking mechanism comprises the catch 1 for receiving the locking bolt 14 and the pawl 2 for locking the catch 1.

The rotary latch 1 usually has a fork-shaped inlet slot formed by load arm and catching arm, into which the locking bolt 14 of a vehicle door or flap 8, in particular the boot lid, arrives when the vehicle door or flap 8 is closed.

The locking pin 14 then rotated by means of the catch arm, the rotary latch 1 from an open position to a closed position. If the catch 1 has reached the closed position, it is latched in this position via the pawl 2 and the vehicle lock assumes a closed state. The locking pin 14 can not leave the inlet slot of the rotary latch 1, since this is prevented by the load arm. This detent position is called main detent position. There is a vehicle lock, in particular motor vehicle lock, with a second latching position, namely the so-called pre-latching position. The pre-detent position serves to intercept the corresponding vehicle door or flap 8 when it does not reach the main detent position when closing. In the Vorraststeilung the catch 1 is therefore not completely closed, however, an opening movement of the catch 1 is already prevented by a pawl 2. Therefore, the area of the rotary latch 1, which receives the pawl 2 in this position, referred to as a pre-detent. Finally, in the main catch position, the catch 1 is completely closed. The pre-restraint thus represents a transition state between the opened state and the main rest and is provided for safety reasons.

In one embodiment, a blocking lever for holding the pawl in the main latching position and / or an ejector lever for pivoting the pawl out of engagement with the rotary latch may additionally be provided. The vehicle lock of Figure 1 has a housing 22 and a concealed from the housing 22 SIM card receiving unit 6 for a SIM card 7 or eSIM. The receiving device can communicate using the SIM card recording unit 6 and the SIM card 7 and a mobile radio unit with the charge output station 16, that is, data exchange.

The charge output station 16 in this way sends the reference code 10 to the vehicle lock and at the same time it is possible to monitor the loading process and / or discharge process by the camera 12 in real time. Recordings of the camera 12 during the monitoring of the loading process and / or unloading process can be stored as a video recording for a later viewing. Alternatively or additionally, it is also possible that the images of the camera 12, for example, via a data stream to an external unit, such as a smartphone of a vehicle owner or a screen in a control center of a delivery service, are sent.

The vehicle lock 1 comprises a code transfer device 4 and a control unit 5. These can not be seen in FIG. 1 because these electronic components are located within the housing 22. Attached to the vehicle lock visible are a charge ID scanner 1 1 for scanning a bar code 33 of a charge 17, LEDs 13 as a display device and the camera 12. In particular, exactly three LEDs 13 are provided, preferably with the colors green, yellow and red. Alternatively, at least 1 or 2, but less than 5 LEDs 13 may be provided.

As shown in FIG. 1, the vehicle lock is attached to a vehicle flap 8 on the rear side of the vehicle 19 and is visible and accessible to the outside only when the vehicle flap 8 is open.

The latch bolt 14 is attached to the vehicle body and engages with the vehicle lock when the vehicle door 8 is closed.

FIG. 2 shows the control unit 5 comprising a processor 23 and a memory 24, on which, inter alia, for example the reference code 10 and / or instructions executable by the processor, ie loadable software code, are stored. A vehicle control interface 25 provides a data connection between the control unit 5 and external control devices 27 such as the central locking system, the door control unit (DCU), and / or the vehicle's electronic control unit (ECU). Access to a plurality of vehicle data and status information and / or to cause the vehicle lock to be transferred to a locked or unlocked state by the control unit 5 and / or control of an automatic opening and / or closing device by the control unit 5 can thus be made possible. A receiving device interface 26 represents a data connection between the control unit 5 and the receiving device 3. The control unit 5 can thereby receive the reference code 10 from the receiving device 3 and exchange and / or communicate data, for example via the receiving device 3 with, for example, a charge dispensing station 16 by means of a mobile radio connection, which also allows data exchange and not only an acoustic signal exchange, for example by GPRS, UMTS, 3G, 4G, etc. Via the receiving device 3, data about the delivery can be exchanged with the charge output station 16. For example, the control unit 5 can be set up so that a notification about receipt of the reference code 10 and thus via a lock opening is sent to the charge delivery station 16 and subsequently via a completed closure of the motor vehicle lock after loading and / or unloading. Also, shots of the camera 12 may be sent to the charge output station 16. Likewise, further data such as a charge status, payload weight or the like can be exchanged via the receiving unit 3 with an external body. Also, via the receiving unit 3, a data exchange on the access-controlled loading and / or unloading with a vehicle owner, for example via an app on a smartphone of the vehicle owner, performed.

A code transfer interface connection 29 enables the data exchange in particular via a data line between the control unit 5 and the code transfer interface 4.

The code transfer interface 4 can thereby pass the obtained access code 30 to the control unit 5. In particular, the control unit 5, in turn, can transmit, for example, data representing an acknowledgment document to the code transfer interface 4 so that the code transfer interface 4 can transmit the receipt to the access code unit 28 of the load carrier 18.

A functional device interface 31 establishes a data connection between the control unit 5 and at least one functional device 32, e.g. a charge input control device, in particular charge ID scanner 1 1, a load monitoring device, in particular camera 12, a display device, in particular LED 13, a speaker and / or a lighting means.

The at least one functional device 32 can be operated and controlled in this way with a particularly simple structure by the control unit 5. FIG. 3 shows schematically and by way of example the method for access-controlled loading according to the above-described aspect of the invention.

At a charge output station 16 or by a charge output station 16, a reference code 10 and an access code 20 identical to the reference code 10 are generated, which is shown by way of example and purely illustratively as "1234".

At the charge output station 16 or by the charge output station 16, the reference code 10 is sent to the receiving device 3 of the vehicle lock of the vehicle 19, which sends the reference code 10 to the control unit 5.

Further, at the charge discharge station 16 or the charge discharge station 16, the access code 20 is transmitted to the access code unit 28 of the load carrier 18, and a charge 1 7 to be loaded into the vehicle 19 is transferred to a load transferring machine 18.

The loading conveyor 18 then transports the load 17 to the vehicle 19. As soon as the loading conveyor 18 and thus its access code unit 28 reach a predefined range of the vehicle lock, that is less than a certain distance away from the vehicle, the loading conveyor 18 transfers in particular by means of Access code unit 28 preferably automatically access code 20 to the code transfer interface 4, which sends the obtained access code 30 to the control unit 5.

The control unit 5 now compares, in particular using a comparison module, whether the reference code 10 is equal to the obtained access code 30, which is the case in FIG. 3 by way of example. If the comparison shows no match, the vehicle lock remains in the locked state. However, if the comparison yields a match as shown by way of example in FIG. 3, the control unit 5 sends a signal to Unlock the vehicle lock to a locking control device, such as the central locking system, DCU and / or ECU.

The vehicle flap 8 can now be opened, so that the loading conveyor 18 can make the loading of the vehicle 19 with the cargo 17.

For example, a bar code 33 indicated in FIG. 3 serves as a charge ID for the purpose of incoming goods inspection, preferably by a scanner or a camera, which may be integrated in the vehicle lock.

An access-controlled unloading proceeds according to the same method, only that the loading conveyor 18 removes previously stored in the vehicle 19 17 charge. In a combined loading and unloading process, at least a portion of the previously stored in the vehicle 19 17 charge is discharged from the loading conveyor 18 and loaded new charge 17 in the vehicle 19.
