[0002] Commercial vehicles are commonly used, for example, by service technicians to reach job sites and transport necessary materials. However, individual vehicles within a larger fleet are often equipped differently, complicating the organization of work assignments and leading to unnecessarily long journeys or detours.

[0003] German patent application DE 20 2013 100 697 U1 describes a device for controlling the loading of a service vehicle, in which containers holding specific tools or spare parts are stored in a list. When the vehicle is loaded, the containers are detected and a release signal is generated when the containers on the list have been loaded.

[0004] The subsequently published DE 10 2009 050 756 A1 relates to a method and a device for detecting missing or newly added objects in a vehicle, wherein the vehicle travels a distance from a starting point to a destination in several journey segments, and furthermore a vehicle having such a device.

[0013] DE 101 49 454 A1 relates to a method for loading and unloading delivery vehicles that transport parcels or the like from a distribution point to several different delivery addresses, wherein the parcels are made available at the distribution point in a generally random order.

[0014] DE 10 2013 101 002 A1 concerns a parts warehouse for spare parts for vehicles to be serviced or repaired, in particular heavy-duty trailer vehicles.

[0015] DE 10 2017 008 752 A1 relates to a device for recording the loading and unloading of a delivery vehicle.

[0016] The present invention is based on the objective of providing a material inventory management system that enables particularly efficient order processing.

[0017] According to the invention, this problem is solved by a method with the features of claim 1 and a material inventory management system with the features of claim 8. Advantageous embodiments and further developments are described in the dependent claims.

[0018] In the inventive method of the type mentioned at the outset, a material inventory list is provided, by which at least one piece of content information is assigned to each storage device. This content information relates to data indicating how much of what is located in which storage device. The start of order execution is recorded, and during order execution, the operation of the storage devices is recorded, as are any changes in the contents of the storage devices. Based on these recorded operations, material consumption is recorded. The material inventory list is updated based on the recorded changes in contents.

[0019] This method advantageously translates changes to the contents of storage devices during the execution of work for a job directly into an update of the material inventory list. Since the vehicle has an optimally updated material inventory list, reliable information about the location of each part within the vehicle is always readily available.

[0020] The operable storage devices may include, for example, drawers, compartments, boxes and / or plug connections, such as sockets, other electrical contacts or a fastening device.

[0021] An "activation" of a storage device can be recorded, for example, when a suitable sensor detects the opening of a drawer or compartment, the removal of a box, and / or the connection or disconnection of a storage device's plug. Furthermore, the insertion or removal of a storage device or the occupation of a space within a storage device can be recorded as an activation.

[0022] The recorded actions are stored, in particular by “logging” the actions of storage devices.

[0023] A storage unit in the vehicle is specifically provided for the provision of the material inventory list. The material inventory list includes information about which materials, spare parts, or tools are assigned to a particular storage device. The content information generally concerns data indicating how much of each item is located in which storage device. It can also indicate whether certain parts should be in a storage device even though they are currently missing and may need to be replenished.

[0024] To detect the start of a task, user input is recorded, for example, via a button or switch. Furthermore, activities within a passenger or cargo area of ​​the vehicle can be recorded, such as the open or closed state of a vehicle door, indicating user activity in that area. The start can also be detected by the activation of a storage device. Alternatively or additionally, the user's position or movements within the vehicle or its surroundings can be detected, or electromagnetic signals can be analyzed, such as the approach of a device emitting electromagnetic radiation.

[0025] Furthermore, the completion of order execution can be recorded, in which case it can be determined in particular which actions of the storage devices were recorded "during" order execution. The recording of completion can be analogous to how the start of order execution was recorded, i.e., based on user input or by detecting activity in specific areas of the vehicle or its surroundings. The inventory list is updated specifically after the completion of order execution has been recorded.

[0026] Changes in the contents of storage devices, particularly those in use, can be automatically detected. This can be achieved using sensors that, for example, capture video data, recognize barcodes, perform near-field communication (RFID) using electromagnetic signals, or detect weight or weight changes. Specifically, parts located within the storage devices are monitored.

[0027] To detect the activation status of a storage device, a sensor can be used, such as a contact switch, a sensor for measuring weight or weight changes, an optical sensor, or an electromagnetic sensor. Sensors can be installed in the vehicle near the storage devices to detect their activation status. For example, they can detect whether a space designated for storage devices is occupied, such as by means of a contact switch, by measuring weight, an optical sensor, or an electromagnetic sensor. Furthermore, actions such as opening a drawer or removing a box can be detected. Separate sensors can also detect actions, or the storage devices themselves can incorporate sensors for activation.

[0028] In further training, a content change user interface is generated based on the recorded actions. This interface is used to record content changes in the activated storage devices. Specifically, the content change user interface is displayed after the completion of a task has been detected. This allows, advantageously, information to be queried from a user via a dialog system.

[0029] During training, the content change user interface includes a list of content information assigned to the activated storage devices. This advantageously utilizes the fact that the activations of the order devices are recorded and stored during order processing.

[0030] For example, the content modification interface can display parts located in the activated storage units to the user. The user can then confirm that they have removed specific parts or items from a storage unit, confirm the quantity, and, if necessary, initiate a reorder. The data collected in this way can be used to generate an invoice.

[0031] In further training, the activated storage devices are highlighted when the content change user interface is displayed, particularly by means of a light signal. This makes it advantageously easier for the user to see which storage devices have been activated.

[0032] Highlighting occurs particularly after the completion of the order, for example, while the user is returning removed parts to the vehicle's storage compartments or while generating an invoice. Highlighting can also occur during the order process itself.

[0033] To highlight specific order-related equipment, relevant storage devices can first be identified. These are, for example, storage devices containing specific parts that are needed to complete an order, need to be returned to storage, are to be delivered or ordered, or have been removed. Highlighting relevant storage devices with a light signal can be done in a known manner, for example, using light sources or light signal panels located in the vehicle, particularly in close proximity to the storage devices, or on the storage devices themselves. The light source can also be integrated into the storage device itself. Light sources such as LEDs can be used for this purpose.Different light emissions can be generated, such as varying colors and brightness, or with a dynamic effect like flashing light. This allows the user to easily identify the relevant storage devices.

[0034] Storage devices can be highlighted analogously if they are in a specific operating state, such as being open, empty, improperly secured, or disconnected. Specifically, storage devices in an open operating state are highlighted. The operating state can be detected using various sensors, such as contact switches, video sensors, weight sensors, or electromagnetic sensors. Highlighting can also occur where a storage device is not detected in its intended location; for example, a compartment is illuminated if a designated box has not been placed in it. Furthermore, a storage device intended to hold a tool can be highlighted if the tool is not detected within the device.In addition, empty storage devices can be detected and highlighted.

[0035] For example, the number of times a storage device is activated can be counted, for instance, using a ring counter. After a predetermined number of activations, it can be assumed that the material stock in the storage device has decreased sufficiently to trigger a reorder. User input can also be recorded for this purpose. Such inventory monitoring is particularly suitable for small parts, such as screws, gaskets, sealants, or similar items.

[0036] Data collected in this way can also be taken into account when generating invoice data, for example by billing a flat rate for certain consumables and supplies.

[0037] During further training, the updated inventory list is transferred to an external unit. This allows for the advantageous external recording of which materials are present on board a vehicle, for example, in order to assign specific tasks to the vehicle.

[0038] During further training, a material requirement, in particular a target inventory list, is provided, and reorder data is generated and output based on the updated inventory list and the material requirements. This allows missing parts to be reordered to replenish the vehicle's stock.

[0039] A reorder can be triggered automatically and transmitted to a suitable unit, such as a supplier. Alternatively or additionally, manual input can be recorded, such as user confirmation or the selection of a specific procurement option. Several procurement options can be displayed and selected for the user, and it can also be determined whether certain procurement options are preferred based on specific optimization criteria. For example, it can be automatically determined which method can be used to procure missing parts particularly quickly, cost-effectively, or with minimal additional travel distance for the vehicle.

[0040] During training, the start and / or end of task execution is recorded using a control device, and a documentation mode of the control device is activated during task execution. Alternatively or additionally, the control device's administration mode can be activated when no task is being executed. This allows the control device to be advantageously configured so that the user has optimal operating options available depending on the context of task execution or administration.

[0041] When documentation mode is activated, data about order execution is recorded. For example, the activation of storage devices can be automatically recorded and saved.

[0042] During further training, data for determining labor costs and / or travel expenses is automatically collected. This data includes, in particular, the duration required to complete work on a job and / or the travel time or distance covered by the vehicle. This data can be automatically collected using the vehicle's tracking systems. Furthermore, the time between arrival at the job site or the start of work and completion of the work or the generation of an invoice can be automatically measured. Additionally, user input can be recorded, such as information about the travel route and / or working time.

[0043] During training, invoice data is generated, either automatically or upon user input. This process checks which storage devices were activated and records which items were actually removed from the activated storage devices. This data is collected primarily using the content modification user interface described above.

[0044] Furthermore, removed parts and consumed materials can be automatically recorded, for example using video sensors or other sensors, and user input can also be recorded for confirmation.

[0045] The material inventory management system according to the invention of the type mentioned at the outset comprises a functional control unit for providing a material inventory list, by which at least one piece of content information is assigned to each storage device. This content information relates to data indicating how much of what is located in which storage device. It further comprises a detection unit for recording the commencement of order execution. The detection unit is configured to record, during order execution, the actuation of the storage devices and any changes in their contents, whereby material consumption is recorded based on the actuations. Furthermore, it comprises an operating device configured to output a content change user interface for recording any changes in the contents of the actuated storage devices, based on the actuations.The inventory list can be updated based on the recorded changes in content.

[0046] The system according to the invention is particularly designed to implement the method described above. It therefore has the same advantages as the method according to the invention.

[0047] The invention will now be explained using exemplary embodiments with reference to the drawings. Fig. 1A and Fig. Figure 1B shows an example implementation of an order management system, Fig. Figure 2 shows an example of how an order is processed. Fig. 3A and Fig. 3B shows examples of displays that can be generated when managing orders, Fig. Sections 4A to 4F show examples of other displays that can be generated when managing orders. Fig. 5A to 5F show examples of displays that can be generated when performing work for orders, Fig. 6A and Fig. 6B shows examples of other displays that can be generated when managing orders, Fig. 7A to 7C show examples of other displays that can be generated when managing orders, Fig. 8A to 8D show examples of other displays that can be generated when performing work for orders. Fig. Figure 9 shows an exemplary embodiment of a shelving system with storage devices and Fig. Figure 10 shows another embodiment of the components of an order and material management system in a vehicle.

[0048] With reference to the Fig. 1A and Fig. Section 1B describes an example implementation of an order management system.

[0049] The order management system comprises several vehicles 11, 12, 13, 14, which are connected to a central control unit 15 via data transmission. The data connection is established in a manner known per se, for example, via a mobile network connection or another network, particularly the internet. In this embodiment, vehicles 11, 12, 13, 14 and the central control unit 15 each include suitable interfaces (not shown). In other embodiments, the data connection can be established via additional devices, for example, a driver's mobile phone, which is connected to both the central control unit 15 and the vehicles 11, 12, 13, 14.

[0050] One of the vehicles 11, 12, 13, 14 is an example in Fig. 1B shown in detail.

[0051] Vehicle 11 has an interior comprising a passenger area 11a and a cargo area 11b. The passenger area 11a is formed here by the driver's cab of vehicle 11 and is separated from the cargo area 11b by a continuous wall. In other embodiments, a passageway between passenger area 11a and cargo area 11b may be provided, or the interior may be continuous, so that passenger area 11a and cargo area 11b are separated from each other only by an imaginary boundary. Specifically, passenger area 11a is defined as the area surrounding a driver's seat of vehicle 11, and optionally also other seats of vehicle 11.

[0052] In passenger compartment 11a, a first user device 16 is arranged, which in this embodiment comprises a touchscreen permanently installed in passenger compartment 11a. In charging compartment 11b, a second user device 19 is arranged, which in this embodiment is designed as a tablet computer. Furthermore, in this embodiment, a holder for the tablet computer is provided, permanently installed in charging compartment 11b, which securely holds the tablet computer during travel of the vehicle 11 to prevent it from falling out or being damaged.

[0053] In further embodiments, instead of the first user device 16, a holder or mount for a mobile user device is provided, in particular for a mobile phone or a tablet computer. Furthermore, the second user device can be permanently installed in or permanently connected to the charging area 11b.

[0054] In a further embodiment, instead of the first 16 and the second user device 19, a single user device is used, which is particularly mobile and can be used both in the personnel area 11a and in the charging area 11b. Suitable mounts or holders can be arranged in the personnel area 11a and in the charging area 11b, in particular with a connection device through which a connection to the user device can be established and / or its presence can be detected.

[0055] In loading area 11b, storage devices 17.1 to 17.6 are arranged, each with an associated lighting unit 18.1 to 18.6. In this embodiment, the storage devices 17.1 to 17.6 are designed as drawers 17.1 to 17.6 and compartments 17.1 to 17.6 of a shelving system. Alternatively or additionally, they can comprise boxes, crates, cases, brackets, or other devices designed in a known manner. The crucial point is that the storage devices 17.1 to 17.6 are suitable for receiving and / or holding objects, such as tools, spare parts, consumables, accessories, or documents. Similarly, liquid or gas containers can be provided.

[0056] The storage devices 17.1 to 17.6 are arranged at specific positions within the loading area 11b. In this embodiment, a cabinet or shelving system is installed in the loading area 11b for this purpose, into which the drawers 17.1 to 17.6 can be inserted at defined positions. Contact switches are provided that are actuated by properly inserted drawers 17.1 to 17.6, while they are not actuated if the drawers are incompletely or incorrectly inserted.

[0057] Alternatively or additionally, storage devices 17.1 to 17.6 can include locking devices and sensors for the closed state. For example, the storage devices 17.1 to 17.6 can be designed as compartments 17.1 to 17.6 of a shelving system into which boxes or other objects can be placed or inserted. In this example, such a compartment 17.1 to 17.6 has a locking element that prevents the object inside from falling out. A sensor detects whether the locking element is closed or open, or whether a storage device 17.1 to 17.6 is installed at a specific position in the shelving system.

[0058] The storage devices 17.1 to 17.6 can also be actuated. In this embodiment, actuating a storage device 17.1 to 17.6 means pulling out a drawer or opening a compartment. Depending on the design of the storage devices 17.1 to 17.6, actuations can be implemented in other ways, for example, by detecting that an object is removed from a holder, a fastener is opened, or an electrical contact is interrupted. In particular, actions that allow stored objects to be removed or released are considered actuations.

[0059] In further embodiments, the storage devices 17.1 to 17.6 also include an identifier, for example an RFID chip, a barcode, specifically designed electrical contacts, or another marking that can be detected by an optical, mechanical, electrical, electromagnetic, or other sensor. In this case, the vehicle 11 includes sensors that detect the storage devices 17.1 to 17.6, for example, when they are loaded into the loading area 11b or when they are positioned at a specific location within the loading area 11b. For example, drawers 17.1 to 17.6 can be provided with different identifiers, and it can be automatically detected which drawer 17.1 to 17.6 is inserted at which position in the racking system. Similarly, for example, boxes or cases can be identified that are in a specific position in a compartment 17.1 to 17.6.6 are positioned in loading area 11b. In addition, individual items can have identifiers that are formed analogously and by means of which it can be recorded which item is located in a storage device 17.1 to 17.6.

[0060] In this embodiment, at least one of the storage devices 17.1 to 17.6 has a charging port to which an electrical device can be connected to charge a battery. The system detects whether a device is connected, and in particular also detects the type of connected device or the individual device, for example, by means of an identifier.

[0061] In this embodiment, the lighting units 18.1 to 18.6 associated with the storage devices 17.1 to 17.6 comprise light-emitting diodes (LEDs) which, depending on the control signal, are either switched off or illuminate green or red. They are arranged in close proximity to the storage devices 17.1 to 17.6, in particular directly above them. In further embodiments, the lighting units 18.1 to 18.6 are integrated into the storage devices 17.1 to 17.6, for example, in the area of ​​a drawer 17.1 to 17.6 visible from the front. In yet another embodiment, the lighting units 18.1 to 18.6 comprise several light sources, for example, LEDs, which can illuminate in varying numbers, for instance, to indicate the fill level of a storage device 17.1 to 17.6.

[0062] The storage devices 17.1 to 17.6 and lighting units 18.1 to 18.6 are each coupled to each other in pairs and to a function control unit 17. The function control unit 17 comprises a multitude of physical interfaces to the storage devices 17.1 to 17.6 and lighting units 18.1 to 18.6, in particular also to the racking system, to the vehicle 11's equipment, especially via a CAN bus, as well as to the first 16 and second user device 19, these connections being established wirelessly in the exemplary embodiment via WLAN or another wireless network.

[0063] With reference to Fig. Section 2 describes an example of order processing. This example is based on the order management system described above.

[0064] In a first step, order data is generated and transmitted. In this example, this is done by a heating and air conditioning system that independently detects a need for maintenance and generates a corresponding order. The order data includes information about an order description, i.e., the type of work to be carried out, and an order location, i.e., a geographical position where the work is to be performed, or corresponding data that allows identification of the heating and air conditioning system and its location. In this example, the order data is transmitted via the internet.

[0065] Alternatively, a simple error code can be generated and sent to keep the transmitted data volume as low as possible. The evaluation for generating the order data then takes place in the central control unit 15.

[0066] In a second step 21, the order data is received by the central control unit 15 of the order management system. An interface is provided for this purpose, which receives and evaluates data via the internet.

[0067] In a further step 22, vehicle status data is retrieved. In this embodiment, the necessary data is provided by the central control unit 15. In steps 24a, 24b, and 24c, vehicles 11, 12, 13, and 14 provide information about their current position, a planned route, and appointment data for planned trips and already scheduled work, as well as information about materials, spare parts, and tools available in vehicles 11, 12, 13, and 14. Furthermore, information about the driver or another employee currently assigned to vehicle 11, 12, 13, or 14 is provided, such as employee identification and qualifications. An interface 23 is provided for receiving the data.

[0068] In another embodiment, the vehicle status data can be retrieved by transmitting direct requests to vehicles 11, 12, 13, and 14 of the fleet via interface 23. These vehicles then send the required information.

[0069] In this embodiment, interface 23 to the vehicle fleet is included by the central control unit 15. In other embodiments, an external server can be used instead of interface 23. This external server manages, updates, and provides information about the vehicle status data of vehicles 11, 12, 13, and 14 as needed. The vehicle status data can be requested, for example, at regular intervals or automatically provided when the status of vehicles 11, 12, 13, and 14 changes. The vehicle status data stored on the external server can then be accessed via appropriate interfaces.

[0070] In a further step (25), it is determined which vehicle (11, 12, 13, 14) of the fleet is best suited to carry out the work for the order. This takes into account when and where other orders are already scheduled for vehicles 11, 12, 13, 14. Furthermore, it considers which materials, spare parts, and tools are on board vehicles 11, 12, 13, 14, as well as which employees are traveling with these vehicles and what qualifications they possess. For example, certain maintenance work may only be carried out by employees with specific qualifications. Additionally, it is considered whether any missing materials, spare parts, or tools need to be procured for the order, for example, by picking them up from a specific location and / or ordering and delivering them to a specific location, and what impact this might have on the execution of the order.

[0071] Furthermore, the system considers whether information exists regarding the urgency of the order; if necessary, a particularly urgent order can be prioritized higher than other orders so that it can be executed as quickly as possible, even if this results in a less than optimal time or cost process. In another implementation, priorities are assigned to incoming orders, and planning is based on these priorities.

[0072] To determine the most suitable vehicle 11, 12, 13, or 14, the available and relevant information is processed mathematically to solve an optimization problem. Optimization criteria are defined for this purpose; for example, orders should be executed as quickly, cost-effectively, with high quality, and economically as possible, and these criteria can be weighted. Additionally, user input can be recorded, such as to assign a specific order to a particular vehicle 11, 12, 13, or 14.

[0073] In another embodiment, the optimization process takes into account information about previous orders and historical data, such as the time required to complete an order depending on the type of order, the order location, the relevant equipment, or specific employees. In this way, particularly through artificial intelligence or machine learning methods, as much information as possible can be used for optimization.

[0074] Furthermore, it can be determined whether the error code transmitted by a system matches the work performed. If necessary, adjustments can be made to the order preparation for future orders (adjustments to the tool list, spare parts list).

[0075] In a further step 26, execution data is generated. This data is transferred in step 27 to the vehicle 11, 12, 13, 14 selected during optimization and received in a further step 28. The execution data includes information required to carry out the order. This includes, in particular, the order name and location, as well as information about the planned execution time, any special features of the order, information about required materials, spare parts, and tools, and, if applicable, options for procuring missing parts. Execution data can be supplemented manually by user input.

[0076] In another embodiment, confirmation data is also generated and sent to the originating department of the order. This data confirms that the order has been received and that the corresponding work will be carried out. Additionally, this embodiment includes information about which employee will perform the work and when, whether any preliminary work or preparations are necessary, and / or whether materials need to be delivered to or made available at the work site beforehand.

[0077] In another embodiment, materials, spare parts or tools that are not present in the vehicle are ordered and information about where they can be picked up is sent to vehicle 11, 12, 13, 14.

[0078] In a further embodiment, a vehicle 11, 12, 13, 14, intended for carrying out the work of a specific order, can generate planning change data if changes occur during the execution of the planned work for various orders, for example, due to a time delay, unavailability of materials, spare parts and tools, employee absences, or other events. If, as a result, the planned work for an order cannot be carried out, or not in the planned manner, this can be communicated to the central control unit 15. This unit checks whether and how the work plan needs to be changed, in particular by performing a re-optimization to select a vehicle 11, 12, 13, 14 to carry out the work for the order. The corresponding steps of the method according to the invention are repeated for this purpose.

[0079] In another embodiment, the method is carried out for only a single vehicle 11. In this case, the determination of the most suitable vehicle is omitted, and the execution data is generated in such a way that information about required materials is available in vehicle 11, in particular information about parts not currently present in vehicle 11 and the possibilities for their procurement. Furthermore, the execution data is generated in such a way that optimal processing of multiple orders is ensured. For example, scheduling is carried out so that the execution of the orders takes place according to specific optimization criteria, for example, by minimizing time, costs, or travel distances, or by prioritizing certain orders or types of orders.

[0080] The following are examples of displays that can be generated in the order management system described above in vehicles 11, 12, 13, and 14. In this embodiment, the user devices 16 and 19 of vehicles 11, 12, 13, and 14 are enclosed by an operating device and have an administration mode and a documentation mode. The administration mode is assigned to the personnel area 11a, and the documentation mode to the loading area 11b.

[0081] In general, the administration mode serves to manage and process the available execution data for the orders in vehicles 11, 12, 13, and 14. The administration mode is assigned to personnel area 11a of vehicles 11, 12, 13, and 14, as is the first user device 16, which is located in personnel area 11a. User device 16 therefore displays a user interface through which the tasks of the administration mode can be processed, in particular through user input and information displays.

[0082] In contrast, the documentation mode serves to document the execution of work for a job and to support a user in carrying out that work. The documentation mode is therefore assigned to loading area 11b of vehicle 11, 12, 13, 14. The second user device 19 is intended to be located or used in or near loading area 11b. It therefore displays a user interface that enables the documentation mode to fulfill its tasks. For example, it displays information related to the execution of a job and records user input in this context.

[0083] Since the passenger area 11a is typically better air-conditioned than the charging area 11b, this separation allows the user to perform as many relevant tasks as possible in the passenger area 11a, while at the same time the charging area 11b does not have to be open for too long.

[0084] In other implementation examples, the administration and documentation modes are assigned to different spatial areas. The crucial factor here is the separation of different areas in which different tasks related to orders and the work involved in carrying out those orders are performed.

[0085] In further embodiments, a user device 16, 19 is provided for which both the administration and documentation modes can be activated. For example, the first 16 or second user device 19 can be movably arranged so that it can be moved into both the personnel area 11a and the loading area 11b. Alternatively, only a single user device 16, 19 can be provided, which, for example, is assigned to a specific employee and performs the tasks of the first 16 and second user devices 19. The position of the user device 16, 19 can be detected, and depending on this position, either the administration or documentation mode is activated.

[0086] The administration and documentation modes can be automatically activated for the user device 16, 19 located in the correspondingly assigned areas 11a, 11b, whereby the location can be detected in various ways, for example, by the signal strength of a wireless data connection. Alternatively or additionally, the administration or documentation mode can be activated manually, for example, by means of a switch or button provided by the user device 16, 19.

[0087] With reference to the Fig. 3A and Fig. Section 3B explains examples of ads that can be generated when managing orders.

[0088] The displays are shown particularly on the first user device 16 of a vehicle 11 of the above with reference to the Fig. 1A and Fig. 1B explained order management system output. It is assumed that the management mode is activated for this first user device 16.

[0089] The display includes a map section 31 showing a road network. At the respective geographical locations, task locations 32 are marked, representing intermediate destinations 32 of a planned route 33 for vehicle 11. The current position of vehicle 11 is marked on the map section 31 as an arrowhead 33a. The task locations 32 are numbered to indicate the order in which the first, second, third, and fourth tasks are to be carried out.

[0090] At the bottom of the display, information field 34 shows the currently executed job, identified by the number "01". This information field includes an address (i.e., the job location) and a time at which the work is scheduled to be carried out. It also displays the estimated time of arrival at the job location, the estimated travel time, and the current distance. Next to this information field, at the bottom, is another information field 35 with information about the following job. This field displays the number "02", the time of execution, and the name of the client. Finally, at the bottom, there is another information field relating to the job after next, which displays only the number "03".

[0091] The display also includes a warning symbol 36, which is shown at the top. In the exemplary embodiment, this symbol issues a warning that one or more drawers of a shelving system in the loading area 11b of the vehicle 11 are not properly closed. Alternatively or additionally, a warning can be issued if required materials, spare parts, or tools are not on board the vehicle 11 or in the event of other faults.

[0092] In this embodiment, the first user device 16 comprises a touchscreen. The user can activate this touchscreen in the area of ​​the information field 34 for the current job to access more detailed information about the work currently being carried out. Alternatively, the user can touch the touchscreen in the area of ​​the first job location 32 in the map section 31. Other methods of operation, selection, and activation may be provided alternatively or additionally, in particular by means of a touchpad, dial, joystick, or mouse. Upon activation, the information displayed in Fig. 3B shown display with an order designation 34a with a more precise description of the work to be carried out or the error message present, an estimated duration 34b of the work and a button 34c by means of which a call to the client can be started.

[0093] Similarly, the user can touch the touchscreen in the area of ​​information field 35 for the next order or the second order location 32 in map section 31 to access detailed information about the following order.

[0094] In further embodiments, when detailed information about an order is displayed, the assigned order location 32 in the map section 31 is marked in a special way, for example by color, by a special symbol or by a dynamic effect, such as a flashing.

[0095] With reference to the Fig. Sections 4A to 4F explain examples of displays that can be generated when managing orders. In the case shown, a user—with management mode activated—has one of the above-mentioned displays related to the Fig. 3A and Fig. 3B explained that a button is pressed in such a way that detailed management of the specific order "01" is carried out. The following displays are also shown on the first user device 16 of vehicle 11 of the above with reference to the Fig. 1A and Fig. 1B explained order management system issued.

[0096] The ad in Fig. 4A includes, analogously to those in the lower section of the Fig. The information fields shown in 3B contain detailed information about the currently processed order. These fields are in Fig. 4A, however, is located in the upper part of the display, where it is moved, for example, after activation in the area of ​​information field 34 for the currently executed order. The lower part of the display contains a material list 401, which lists the tools, materials, and spare parts necessary for carrying out the current order. The material list 401 includes information on the item's name, its designated position in loading area 11b, the required quantity, and the current stock on board the vehicle 11. The list also displays indicator lights 402, which can assume different states: If an item is not present on board the vehicle, no indicator light 402 is displayed; if the item is in a storage device 17.1 to 17.6, the indicator light 402 changes color.

[0097] In other embodiments, different conditions for the appearance of the test light 402 may be provided. The appearance of the test light 402 can be formed in various ways known per se, for example with different colors, brightness, or with a dynamic effect such as flashing. The appearance of the test light 402 can also depend on the state of a lighting unit 18.1 to 18.6 associated with the storage device 17.1 to 17.6 and can, for example, be prevented when the lighting unit 18.1 to 18.6 illuminates, changes its color, or is switched off.

[0098] The ad in Fig. 4A further includes a button 403 for starting the current job, which in the present embodiment manually activates the documentation mode and displays a new user interface, such as the one shown below with reference to the Fig. The displays are explained in sections 5A to 5F. Alternatively or additionally, route guidance to the order location can be initiated. Furthermore, a further button, 404, is included, which allows the storage devices 17.1 to 17.6 assigned to the items in the material list 401 to be illuminated and highlighted using the lighting units 18.1 to 18.6; this is also explained in more detail below.

[0099] Based on the in Fig. In the display shown in 4B, further items can be added to the material list 401. The display is largely analogous to the display of the Fig. 4A was formed. Therefore, only differing features are explained.

[0100] Above the material list 401 is a button 405, which can be used to start a dialog for adding items. Adjacent to this is a search field 406, which can be used to enter a search term. The invention uses a keyboard for input; however, alternatively or additionally, speech recognition, barcode scanning, or another method can also be used.

[0101] The display also includes a 407 "Procure" button to open a dialog regarding the procurement of missing materials, and a 408 "Invoice" button to create an invoice. These functionalities are also explained in more detail below.

[0102] At the in Fig. In the case shown in Figure 4C, the user activated the search field 406 and entered a search term, in this case the word "pliers". A results list 409 appears, in which the relevant items identified based on the search term are listed with a description, the required quantity, and the current stock in vehicle 11. The user can now select the desired items in the results list 409 and, if necessary, enter the required quantity. The display also includes a button 410 for adding selected parts to the material list 401 and a button 411 for canceling the search and returning to the display. Fig. 4B.

[0103] The in Fig. The 4D display essentially corresponds to the one shown in Fig. The advertisement shown in 4B and already explained above, however, in material list 401 an item from results list 409 of the advertisement was used. Fig. 4C added. This item is not currently on board vehicle 11, therefore no test light 402 is displayed for it. Instead, in this embodiment, the newly added item is marked by a marker 416, shown here by a dashed frame. Highlighting can be achieved in other known ways, for example by color, brightness, bold or italic type, or a dynamic effect such as flashing.

[0104] At the in Fig. In the case shown in 4E, the user [was] in Fig. In the 4D-shown display, the user clicks button 407 "Procure" and a dialog box opens where they can specify how the missing items should be procured. A list 412 of procurement options is displayed, showing the estimated time and costs for different delivery methods. A checkmark 413 marks the currently selected procurement option.

[0105] In this embodiment, the list 412 of procurement options is generated in such a way that a ranking of the procurement options is determined according to a predefined optimization criterion. The best procurement options according to the ranking are displayed at the top of the list, the less favorable ones further down. In this case, the optimization criterion is that the required time should be minimized. Further optimization criteria could include minimizing costs or travel distance, economic efficiency criteria, or a specific prioritization of certain procurement options.

[0106] The display also includes a total of 414, calculated based on the number of ordered items and their price. Furthermore, it includes the "Procure" button 407, which, when clicked, submits an order using the currently selected procurement option.

[0107] In Fig. 4F displays an order confirmation 415, which signals to the user that the missing items have been successfully reordered.

[0108] In this embodiment, it is provided that the display of the order confirmation 415 is shown again after the order confirmation 415. Fig. 3A or Fig. 3B is issued.

[0109] With reference to the Fig. Sections 5A to 5F explain examples of displays that can be generated when performing work for orders. The displays are shown on the second user device 19 of vehicle 11 above, with reference to the Fig. 1A and Fig. 1B explained order management system output. This second user device 19 is assigned to loading area 11b and the documentation mode is activated.

[0110] The ad in Fig. 5A includes, analogous to the display of the Fig. 4A, Detailed information on the currently processed order is displayed in the upper part of the screen. Below this, a material list 501 is shown, which includes the tools, materials, and spare parts necessary to carry out the work for the current order. The material list 501 includes information on the item's name, its designated position in loading area 11b, the required quantity, and the current stock on board vehicle 11. Furthermore, test lights 502 are shown, the states of which are displayed as above with reference to... Fig. 4A are described.

[0111] For the illustrated articles, safety lights 503 are also displayed, indicating the state of the storage device 17.1 to 17.6 associated with the article: In the exemplary embodiment, the safety light 503 is only displayed if the storage device 17.1 to 17.6 is open, released, removed, or in some other activated state. Such an activated state can also be triggered if an object, for example a tool, is not in its designated place.

[0112] As long as one of the storage devices 17.1 to 17.6 is in such a state, the corresponding safety light 503 is illuminated. Furthermore, a warning symbol 536 is displayed in the upper part of the display. This is a safety measure intended to prevent the vehicle 11 from being moved before the load is securely stowed or, for example, before tools have been correctly reloaded into the vehicle 11 and possibly forgotten.

[0113] In this embodiment, the operating state of the storage devices 17.1 to 17.6 is detected by various sensors depending on the type of fastening or storage. For example, closed drawers are detected by a contact switch, the position of power tools is determined by their connection to a charging point in the network, and the position of certain materials can be determined by optical or electromagnetic sensors, such as near-field communication (RFID) or Hall sensors.

[0114] The display also includes a button 505 for starting a dialog for adding missing parts, as well as a search field 506, which, analogous to the one above, relates to Fig. 4B and Fig. The search function described in section 4C can be used.

[0115] At the in Fig. In the case shown in Figure 5B, the user activated the search field 506 and entered a search term, in this case the word "Fitting". A results list 509 appears, in which the relevant articles identified by the search term are listed with a description, their intended position in vehicle 11, and the current stock in vehicle 11. Markers 514 in the display highlight that for the top two articles in the results list 509, the lighting units 18.1 to 18.6 for corresponding storage devices 17.1 to 17.6 are illuminated. This allows the user to see in which storage devices 17.1 to 17.6 these articles can be found.

[0116] Furthermore, by pressing an entry in the results list 509, a flashing of the corresponding lighting units 18.1 to 18.6 for corresponding storage devices 17.1 to 17.6 is activated.

[0117] The in Fig. The markings 514 shown in Figure 5B, in the form of dashed frames, serve only for clarification and are not actually displayed in this example. Instead, the corresponding items are highlighted by a modified font, for example, by a different color. Other graphical highlighting methods can also be used.

[0118] The user can now select the desired items from the results list 509, indicated by the checkmarks 513 located to the left of the item descriptions. The display also includes a button 510 for adding selected parts to the material list 501 and a button 511 for canceling the search and returning to the display. Fig. 5A.

[0119] At the in Fig. In the case shown in 5C, the following were presented: Fig. Item 5B selected and added to material list 501. The display is essentially the same as that of the Fig. 5A, however with the correspondingly supplemented material list 501.

[0120] At the in Fig. In the case shown in Figure 5D, the user activated another storage device 17.1 to 17.6. In this specific case, he removed a tool, namely a pair of water pump pliers. The name of this item therefore appears in the parts list 501 with a safety light 503, which indicates that activation has taken place.

[0121] At the in Fig. In the case shown in 5E, the user initiated the generation and output of invoice data by pressing the "Bill" button (508). An invoice (516) is displayed, which includes a list of labor costs, travel expenses, materials and spare parts used, and the corresponding prices. It also includes a customer signature, captured in a known manner, such as by scanning or signing on a touch-sensitive surface.

[0122] In this example, the data required to determine labor and travel costs—specifically, the duration needed to complete the work and the travel time or distance—is automatically recorded by the system. This is achieved, for example, via an interface between the functional control unit and the vehicle's sensors for measuring the distance traveled, and by measuring the time between arrival at the job site or the start of work and the generation of the invoice. Alternatively or additionally, user input can be recorded, specifying, for example, the travel route and / or working time.

[0123] In this example, the system also checks which storage devices 17.1 to 17.6 have been activated to generate the invoice data, and a query is created in which the user enters which materials, spare parts, and tools they have actually removed. Alternatively or additionally, the removed items can be automatically recorded, for example, using video sensors or other sensors. This means that items in storage devices 17.1 to 17.6 that have not been activated are not taken into account, while the user is specifically shown the potentially removed items. This simplifies and speeds up the invoice generation process.

[0124] The display also includes a button (511) to cancel the process and another button (505) to complete the process, allowing the invoice to be printed. If the customer's details are known, an invoice can also be sent automatically via email. After the process is completed, the following appears: Fig. 5F shows the representation with the completion confirmation 515 as well as a button 517 to close the completion confirmation 515 and a button 518 to continue with the next order.

[0125] In this embodiment, it is further provided that the inventory of materials stored in the vehicle is also updated based on the change in contents of individual storage devices 17.1 to 17.6, which is recorded when the invoice is generated. The updated data is also made available to the external unit 15, which subsequently takes into account, when the vehicle 11 is in operation, that certain materials are no longer available on board the vehicle 11.

[0126] With reference to the Fig. 6A and Fig. Section 6B explains examples of other displays that can be generated when managing orders. It is assumed that the displays are shown by the first user device 16 in management mode.

[0127] Fig. Figure 6A shows a display with a map section 61, in which a planned route and various order locations 62 arranged along the route are shown. Furthermore, a procurement location 63 is shown along the route, which in this embodiment corresponds to a material warehouse from which the vehicle 11 can collect missing materials. In this embodiment, the user can select the marked customers 62 or the procurement location 63, in particular by touching a touchscreen that displays the information or by means of another input device. If an order location 62 is selected, the corresponding order is marked as the current order.

[0128] The display also includes a button 64 for deleting an order and a button 66 for contacting a customer. In this example, the user can press these buttons 64 and 66 to edit the currently selected order. Additional options for working on an order can be accessed via another button 67, in particular those listed below with reference to the Fig. The displays and input options described in sections 7A to 7C.

[0129] Additionally, the display includes a button 65 for a so-called "safety check." Button 65 comprises an illuminated area 65a, which in this embodiment is designed as a circular area that can be highlighted in color. In this embodiment, the illuminated area 65a is highlighted, for example, by a special color, brightness, or a dynamic effect such as flashing, when a storage device 17.1 to 17.6 in the charging area 11b is in an activated state. Such an activated state indicates that the storage device 17.1 to 17.6 is, for example, not properly closed, not attached in its designated position, or otherwise not in its desired initial state.

[0130] By pressing button 65, the user calls up the in Fig. Figure 6B shows a detailed view that includes Table 68. This table displays the descriptions of goods and their positions, which correspond to the positions of the associated storage devices 17.1 to 17.6. Furthermore, a button 68a for "acknowledge" and an indicator 68b are displayed for each item. The indicator 68b shows that the storage device 17.1 to 17.6 associated with the item is in an activated state, meaning it is not properly closed, it detects the item is missing, or it exhibits another critical characteristic. By pressing button 68a, the user can confirm that the activated state of the storage device 17.1 to 17.6 for this item should be ignored, for example, because a missing tool is to be left at the construction site and picked up later.When acknowledging such a message by pressing button 68a, the storage device 17.1 to 17.6 is no longer highlighted as activated.

[0131] By pressing button 69, all confirmations can be reset, meaning that it is checked again which storage devices 17.1 to 17.6 are in an activated state and these are displayed during the “Safety Check”.

[0132] In this embodiment, it is further provided that when the "safety check" is performed, the lighting units 18.1 to 18.6, which are assigned to the activated storage devices 17.1 to 17.6, are highlighted. In this way, the user can easily identify which storage devices 17.1 to 17.6 are being used when looking into the loading area 11b.

[0133] By pressing button 60, the user returns to the screen in Fig. 6A shown in the advertisement.

[0134] With reference to the Fig. Sections 7A to 7C explain examples of other displays that can be generated when managing orders. It is assumed that the displays are shown by the second user device 19 in management mode.

[0135] In the Fig. In the display shown in 7A, the user is shown data about the order to be carried out in an information field 71, in particular the name and address of a customer as well as a description of the order. Furthermore, the processing time is measured, whereby in this example the time starts automatically when the vehicle 11 reaches the customer. Alternatively, the time measurement can be started and stopped manually.

[0136] Furthermore, a material list 72 is displayed, listing the materials, spare parts, and tools to be used for the order. For each item, the position provided in loading area 11b is displayed, in particular an identifier of an assigned storage device 17.1 to 17.6, and information about the current stock level. It also indicates how many of each item are to be removed, and a button 72b can be used to increase or decrease the specified number. Buttons are also assigned to the items for confirming an entry and for placing an order for the item. A scroll bar 72a is provided to move the displayed excerpt from a longer list. The display also includes a button 75, which, when pressed, displays the information in Fig. The user interface shown in 7B is created for adding further parts, as well as a button 76, which, when pressed, activates the function shown in Fig. The user interface shown in 7C is generated for selecting a procurement option.

[0137] At the in Fig. In the case shown in 7B, the user has the button 75 to add further parts of the Fig. The user interface shown in 7A is activated. An inventory list 74 is displayed, which includes a description, a designated position, a current stock level, and buttons for adding and ordering items in the vehicle's inventory 11. The display also includes a search field 79, which the user can use in a familiar way to search for specific items. A scroll bar 74a can be used to move the displayed section of a longer list.

[0138] After adding more parts, the user returns to the screen in Fig. 7A shown user interface to further edit the material list 72.

[0139] At the in Fig. In the case shown in Figure 7C, the user clicked button 76 to plan a procurement. A list 73 of procurement options is displayed, showing for different procurement methods whether the required materials are available in this way, what the costs are, and what delay this will cause for the customer. The individual procurement options can be selected using buttons; for longer lists, a scroll bar 73a can be used to browse the list. The available procurement options might include, for example, collection from a central warehouse, delivery by a supplier or another vehicle, or other delivery, such as to the customer's address.

[0140] When selecting a procurement option, an additional user interface may be displayed to enter additional details about the procurement.

[0141] In this embodiment, the displayed list 73 of procurement options is generated based on a ranking system that identifies better and worse procurement options according to predefined optimization criteria. These optimization criteria can include, for example, minimizing time delays, travel distances, or costs, and other optimization criteria or combinations thereof can also be used. Furthermore, certain procurement options can be prioritized, for example, if procurement is governed by contracts with suppliers.

[0142] The display also includes a button 77, which, when pressed, displays the current customer's contact details or establishes contact, for example by telephone. The display also includes a button 78, which, when pressed, returns the user to the screen shown in Fig. The user interface shown in 7A is accessed.

[0143] With reference to the Fig. Sections 8A to 8D explain examples of other displays that can be generated when performing tasks for orders. It is assumed that the displays are shown by the first user device 16 in documentation mode.

[0144] In this example, it is further assumed that the user has completed the work required to carry out a task and has subsequently documented the work performed, as well as the materials, spare parts, and tools used. This step can be initiated, for example, by pressing a corresponding button or through automatic detection.

[0145] The in Fig. The display shown in 8A includes an information field 81 with data about the current order, where information field 81 is analogous to information field 71 of the display in Fig. 7A is formed. It also includes a material list 82, which is analogous to the material list 72 of the advertisement in Fig. 7A is formed.

[0146] In this embodiment, the material list 82 includes the materials, spare parts, and tools that were recorded during the execution of the work based on the activation of the storage devices 17.1 to 17.6. For example, the opening of a box by pulling it up in a shelving system is automatically registered, for example, by means of a contact switch, and the parts contained in the box are added to the material list 82. The user can set the number of parts actually removed using the associated buttons 86 and confirm this with a button, and initiate a reorder with another button. If a part was not removed even though the associated storage device 17.1 to 17.6 was activated, the user can, for example, set the number of removed parts to "0" and confirm.

[0147] Missing parts can be added by the user pressing button 82b, whereupon, in particular, the parts shown in Fig. The display shown in 8B and explained in more detail below is generated.

[0148] The display also includes a button 82a, which, when pressed, selects the storage devices 17.1 to 17.6 listed in material list 401 and activates their respective lighting units 18.1 to 18.6. This highlights the storage devices 17.1 to 17.6, allowing the user to easily identify where specific parts have been removed.

[0149] The user can also press another button, 82c, which triggers the creation of an invoice. The corresponding display is shown below with reference to... Fig. 8C explained in more detail.

[0150] The ad in Fig. 8B is used to add parts from an inventory list 83 and is essentially analogous to the display of the Fig. 7B formed. Added parts appear upon returning to the display of the Fig. 8A in the material list 82.

[0151] Once the documentation of the parts used and the invoice parameters is complete, the following appears after pressing button 82c: Fig. 8C shows an automatically generated invoice. The display includes the invoice data (84), a button (84a) which prints the invoice when pressed, another button (84b) which sends the invoice to the customer's email address when pressed, and another button (84c) which registers the order completion and displays the Fig. 8D is generated.

[0152] The ad in Fig. 8D includes a list 85, which is analogous to the material list 82 of the Fig. 8A is set up. However, this list does not record the removal of parts from storage devices 17.1 to 17.6, but rather the storage, i.e., the number of parts placed into storage devices 17.1 to 17.6. In particular, it records which tools are loaded back into the loading area 11b of the vehicle 11. This recording can be done, for example, by measuring the current flow when an electrical device is connected to the vehicle's electrical system to charge a battery.

[0153] Analogous to the "Safety Check" described above, the illuminated areas 87 of list 85 are designed to allow verification of the activation status of the storage devices 17.1 to 17.6. For example, illuminated areas 87 can be displayed in a specific color if a removed tool has not been returned or if a storage device 17.1 to 17.6 has not been properly closed. For instance, open drawers, compartments, or locking devices are indicated in this way. Conversely, the storage devices 17.1 to 17.6 that were activated during the execution of the order are marked in a different color on the illuminated area 87 if they are properly closed or if a removed tool has been returned to its storage. The illuminated area 87 can, for example, be displayed in red or green.

[0154] In the exemplary embodiment, it is further provided that the storage devices 17.1 to 17.6 marked as not properly closed or not present are also marked on the basis of the lighting devices 18.1 to 18.6.

[0155] The display also includes a button 85a, which, when activated, illuminates all storage devices 17.1 to 17.6 previously used during the work, and a further button 85b, which, when activated, starts the next job.

[0156] At the start of a new order, a new list is created in particular, in which the storage devices 17.1 to 17.6 that have been used are stored, in order to subsequently register the parts removed.

[0157] With reference to Fig. Section 9 describes an exemplary embodiment of a shelving system with storage devices.

[0158] The racking system 90 is designed in a manner known per se such that it can be installed in the loading area 11b of the vehicle 11 and provides space for storage devices 91, 92, in this embodiment boxes 91 and drawers 92. Alternatively or additionally, other storage devices 91, 92 may be provided. The storage devices 91, 92 are designed to hold materials, spare parts, tools, and other objects in such a way that they are stored securely in the vehicle 11. In particular, falling during the journey of the vehicle 11 is prevented.

[0159] In the shelving system 90, a specific place is provided for each storage device 91, 92, for example a space for a box 91 or a suspension for a drawer 92. Lighting units 93, in this embodiment an LED, are arranged at these places and can be controlled separately.

[0160] Sensors are also attached to the locations to detect when a storage device 91, 92 is present, for example by means of a contact switch, by measuring a weight, by an optical sensor, or by an electromagnetic sensor. The sensors also detect the actuation state of the storage devices 91, 92, that is, in particular, the opening of a drawer 92 or the removal of a box 91. In other embodiments, separate sensors can be used to detect the actuation, or the storage devices 91, 92 themselves can include sensors for actuation.

[0161] In further embodiments, the storage devices 91, 92 each have an identifier that can be detected by the sensors, allowing the respective storage device 91, 92 and / or its contents to be detected. In further embodiments, sensors may also be provided by which the contents of a storage device 91, 92 are automatically detected, for example, based on weight, by an optical sensor, or by electromagnetic detection, in particular by means of near-field communication (RFID).

[0162] For controlling the LEDs 93 and for reading out the information recorded by the sensors about the occupancy and / or the operating status of the storage devices 91, 92, the racking system 90 is coupled to the function control unit 17 of the vehicle 11, in particular by using one or more interfaces of the function control unit 17.

[0163] The racking system can also include work lighting that can be controlled and, when activated, illuminates a work area. The work lighting can be provided in addition to, or integrated into, the interior lighting of vehicle 11.

[0164] In this embodiment, the racking system includes electrical connections that are supplied with voltage via the vehicle's electrical system. A connection to an external power supply network is also provided, for example, via three-phase current on a construction site.

[0165] With reference to Fig. Section 10 explains another example of the components of an order and material management system in a vehicle.

[0166] The system comprises a function control unit 110, which in turn includes the following modules: an app interface 111; a safety check module 112 for checking whether tools and storage devices are in their proper place; a shelf location marker 113 for marking relevant storage devices and / or relevant locations of a racking system 120; a fill status query 114, for example with a ring counter, for determining a fill status of storage devices for specific parts; and a module for providing power and controlling sockets 115 or a work light.

[0167] The system further comprises a shelving system 120 with the following modules: status LEDs 121 at individual shelf locations, comprising LEDs for red and green light; end position sensors 122, designed as reed switches or Hall sensors; a fill status LED strip, in the exemplary embodiment with several white LEDs, which are provided, for example, at locations for removable boxes or other storage devices to indicate their fill status; and electrical consumers 124, in particular connected to sockets with 230 V voltage.

[0168] The system further comprises: a Power PC 130; at least one tablet computer 140, which is assigned to the personnel area 11a and / or the charging area 11b of the vehicle 11; a smartphone 150 for providing an app interface and / or a WLAN interface, whereby proximity detection can be carried out, for example, based on the WLAN signal; a voltage converter 160; and a relay 170. However, the Power PC 130 may also be omitted, and its functions or tasks may be taken over by the function control unit 110.

[0169] The app interface 111 of the function control unit 110 receives status feedback from the safety check module 112 and from the module for fill status query 114. It provides outputs for tool or material selection for the shelf location marking module 113. It is also coupled to the Power PC 130 and transmits control signals to it for controlling a door and / or a light, in particular vehicle lighting 11.

[0170] The Safety Check module 112 transmits status feedback to the app interface 111 and control signals to the status LEDs 121 of the racking system 120. This allows relevant storage devices to be marked, for example, if they are not properly closed or if storage devices are not in their designated place. The status LEDs 121 then light up red or green. Similarly, the shelf location marking module 113 transmits control signals to the status LEDs 121, but in this case, not to check proper occupancy, but to assist the user when removing or storing parts in the storage devices.

[0171] The end-position sensors 122 of the racking system 120 register changes in the position of the storage devices, for example, when drawers, compartments, and locking devices are opened, or boxes, crates, and cases are removed. Information about the activation is transmitted to the module for fill status query 114 and to the module for the safety check 112. For example, during order processing, the system records which storage devices are activated so that the potentially removed parts can be determined later. This is done primarily using the status feedback transmitted from the module for fill status query 114 to the app interface 111.The module for the fill status query 114 also transmits control signals to the fill status LED strip 123 to mark storage devices by means of white light which are no longer sufficiently filled or which, on the contrary, still have sufficient filling.

[0172] In this embodiment, a fill-status LED strip 123 is provided in close proximity to individual storage devices. This strip comprises LEDs arranged in a row, which emit primarily white light or can be switched between white and red emission. When an activation of a storage device is detected, a ring counter in the fill-status query module 114 registers an additional removal. Depending on the number of removals, the fill status decreases, and fewer LEDs illuminate white. The remaining LEDs can then illuminate red. Alternatively or additionally, the actual removal from the storage device can be measured to control the number of white-illuminated LEDs based on the actual fill status. Other indicators can be used analogously.

[0173] Furthermore, a CAN interface is provided for data exchange between the function control unit 110 and the Power PC 130. The data exchanged via the CAN interface includes, for example, status data or control signals from the tablet computer 140.

[0174] The Tablet Computer 140 is connected to the PowerPC 130 via WLAN. An app interface can display information about the system status or capture user input for controlling system components.

[0175] In this embodiment, the smartphone 150 is connected to the function control unit 110 via WLAN. It provides an app interface through which information about the system status is displayed or user input for controlling system components is recorded. Furthermore, it is intended that the user always carries the smartphone 150 with them, so that the user's location or position within the vehicle 11 can be determined based on the smartphone 150's proximity to the vehicle 11.

[0176] Analogous to the one in Fig. In the embodiment shown in 1B, the first 16 and the second user device 19 can also be implemented using the tablet computer 140 and the smartphone 150 and assigned to the person area 11a and the charging area 11b of the vehicle 11 respectively.

[0177] The voltage converter 160 and the module for supplying power and controlling sockets 115 or a work light are coupled to the relay 170, which in turn controls the electrical loads 124 of the shelving system 120. In this embodiment, this determines which sockets are supplied with power; furthermore, the power drawn can be measured and, like the material consumed, taken into account when generating an invoice.

[0178] The function control unit 110 has interfaces to the racking system 120 and the user devices 140 and 150. It is also connected to vehicle 11 systems via CAN interfaces. This allows the coordination and control of the racking system 120 and vehicle systems via the Power PC 130 or the function control unit 110.

[0179] For example, it can be determined whether a user with the smartphone 150 is near or away from the vehicle. If the user, for instance, removes a heavy box from the vehicle, they may have difficulty operating the vehicle's controls manually. In this embodiment, the system detects that the user is moving away from the vehicle 11 and triggers the closing of the door and the switching off of the vehicle's lights. Conversely, the door opens and the lights switch on when the user approaches the vehicle 11 again, ensuring that even with heavy luggage, they do not encounter any additional difficulties operating the vehicle 11.
