[0001] Method and system for managing a watercraft fleet

[0002] Description

[0003] The invention relates to a method and a system for managing a fleet of watercraft, in particular boards.

[0004] The term “administration” in the following refers to activities that are associated with rental, preferably digitally supported, fleet management (including maintenance) and central, user-independent control of watercraft, in particular water sports equipment such as electrically powered boards.

[0005] Such boards, also called jetboards or powerboards, can be used like a surfboard, allowing the user to achieve planing with minimal effort. Alternatively, the boards can be designed so that the user controls propulsion via a propulsion tool, particularly a paddle, oar, or scull, with this muscle-powered propulsion being supported by the board / watercraft's drive, similar to a padelec.

[0006] JP 2003 026085 A discloses a watercraft in which a water jet propulsion system is implemented with an internal combustion engine. This propulsion system is housed in a solid support that is inserted into a floating body designed like an inflatable boat. Such a watercraft is considerably heavy and can, in principle, only be launched with the aid of a trailer or launching trolley. To overcome this disadvantage, solutions are known in which the actual board is made of several different modules that are relatively easy to assemble, using an electric jet propulsion system instead of an internal combustion engine. One such concept is disclosed, for example, in WO 2021 / 190 941 A1. The jet propulsion system is housed in a stern module to which different bow modules for different applications can be attached, thus creating a modular hardboard concept.

[0007] The publications WO 2019 / 122 321 A1 and EP 3 277 574 B1 describe jetboards in which the jet propulsion is incorporated into an inflatable hull component. While such jetboards are characterized by minimal weight, the disadvantage is that the inflatable structure, which is designed, for example, as a drop-stitch component, is less torsionally rigid than a hardboard, thus making precise steering by shifting weight more difficult.

[0008] Patent application WO 2023 / 077 187 A1 relates to a foilboard with a jet propulsion system featuring an impeller, which is controlled by a controller based on sensor signals so that the propulsion is effective within a specified time window. Also disclosed is a data connection between the controller and a computer, via which a user using the board can be supplied with information.

[0009] Publication WO 2023 / 094 668 A1 discloses a watercraft with an interchangeable drive unit, embodied, for example, as a jet drive, with power supplied by a battery module. The electric drive is equipped with an identification device through which data from the watercraft housing the drive can be read, thus ensuring data compatibility between the drive and the watercraft.

[0010] Such watercraft / boards are used in the manner of a surfboard, with the drive usually being controlled via a remote control held by the user and connected via radio or cable to a control unit of the drive.

[0011] As explained above, propulsion can also be achieved by means of a propulsion tool, in particular a paddle or the like, and can optionally be supported by the drive of the board, in particular the water jet drive.

[0012] A similar concept is described, for example, in US 2011 / 212 691 A1. A remote control is attached to the paddle of an eSUP, which can be used to control the board's propulsion. The remote control can be designed to provide thrust assistance, so that the board is propelled once by the paddle and additionally by the thrust assistance of the board's integrated propulsion system. Alternatively or additionally, a change in direction or stabilization of the directional control can also be achieved by operating the remote control. Accordingly, the remote control is in data communication with the control unit of the board's propulsion system.

[0013] Such watercraft, especially jetboards, are usually sold directly from the manufacturer to the end customer. However, the high price is problematic, resulting in a relatively limited customer base. In addition, such jetboards are not permitted on inland lakes in Germany, limiting their use to coastal waters. However, one problem for private individuals is transporting the relatively heavy and bulky jetboards to the place of use.

[0014] In practice, business models have become established in which the manufacturer sells a fleet of such jetboards to holiday clubs, hotels, etc., where they are then offered for rent by the respective operator. Business models are also known in which manufacturers offer the boards directly for rent at predetermined locations operated by the manufacturer. WO 2020 / 043 958 A1 relates to a method for renting vehicles, whereby, after the expiration of the rental period, an extension of the usage period is possible by the renter entering a code, which is provided by the lessor upon request. The code can be entered via a terminal, an app, or the like.

[0015] EP 3 905 183 A2 describes a system for renting watercraft in which the actual rental process takes place via owner terminals and user terminals connected to a cloud server via the internet. The respective watercraft are equipped with sensors that record their position and propulsion function. The respective signals are connected to the cloud server via a communication module, allowing this information to be retrieved via the owner terminal.

[0016] US 2021 / 0027554 A1 describes a system in which an external unit is attached to a vehicle, for example, a watercraft, through which the vehicle's functional parameters can be recorded and transmitted to a cloud server via a communications network, making this data available to various interested parties, such as vehicle rental companies. This external unit can also be used to process payment services when renting the vehicle.

[0017] Document JP 2021 061037 A relates to a vehicle rental system in which a plurality of rental stations are connected to a management center via a communications network. The user can then rent the vehicle via a smartphone or similar device. A similar system is described in CN 116797325 A.

[0018] US 2022 / 207 450 A1 describes a fleet management system in which the data of a vehicle fleet is managed via a central network. Document DE 10 2020 205 386 A1 discloses a management system for a vehicle fleet, in particular for bicycles that can be rented at unmanned stations. The individual stations are connected to a server that provides a management system that allows the number of bicycles available at each station to be adjusted depending on demand.

[0019] A problem with managing jetboard fleets is that the aforementioned high costs (in the five-figure range per jetboard) also deter operators of hotels, holiday clubs, etc., from purchasing the number of jetboards they need. Another problem is that technology, especially in the area of ​​jetboards, is evolving very rapidly, requiring considerable effort to keep the jetboard fleet up to date.

[0020] In contrast, the invention is based on the object of creating a method and a system for managing a fleet of watercraft, which enables cost-effective and flexible use of the watercraft.

[0021] This object is achieved by a system for managing a watercraft fleet having the features of claim 1 or a method for operating such a system having the features of claim 12.

[0022] Advantageous further developments of the invention are the subject of the subclaims.

[0023] The system for managing a watercraft fleet provides a central office with a large number of electrically powered watercraft, particularly jetboards. The system also provides at least one fleet base, such as a rental station, which receives a fleet of watercraft from the central office. The system is not limited to a single fleet base; in principle, the central office can supply several fleet bases in parallel with up-to-date watercraft / jetboards. The investment required by the fleet base to use the watercraft is minimal, so there is considerable economic interest in offering the watercraft provided by the central office for use / rental.

[0024] In the concept according to the invention, the watercraft are each equipped with sensors which can record functional parameters such as the charge level of a drive battery unit, the position, the driving status, service intervals of the watercraft, an identification of the watercraft or the like. The corresponding signals are then transmitted to a central platform / server in the manner of an IoT system, so that fleet monitoring and, for example, control of the drive is possible via the control center and the fleet base. The watercraft is equipped with an on-board computer or a central processing unit for controlling the drive. Furthermore, part of the system are preferably mobile customer interfaces, for example mobile phones, for which software, e.g.An app or similar solution is provided so that a user can book a watercraft from a fleet base via the central office, depending on the availability of watercraft, and authorize a payment to the fleet base. Instead of the B2C app installed on a mobile phone, a website can also be used as the customer interface. This website can be accessed via a desktop computer or as a mobile website via a mobile phone, tablet, or similar device. This eliminates the "entry barrier" of downloading the app and facilitates access for first-time users.

[0025] Bookings should preferably be made through the central office rather than the fleet base, so that the latter has an overview of the actual use of the watercraft and can react promptly to any oversupply or undersupply. After booking and payment, the fleet base receives the relevant booking information from the central office so that the watercraft can be made available by the fleet base for pickup by the user / customer. Upon handover or return of the watercraft, the central office may receive a portion of the payment made by the user to the fleet base as a commission for arranging the user's booking.

[0026] This creates an end-to-end handover process in which the user generates a ticket when booking the watercraft via the customer interface (B2C app, website (desktop website or mobile website), which is then used, for example, in a B2B app or a B2B desktop computer, for the user's check-in and the handover / pick-up of the watercraft.

[0027] The fleet base can be a single rental station. In principle, the term "fleet base" can also encompass the stations of a chain, such as a holiday club with multiple locations.

[0028] An advantage of the system according to claim 1 is that the watercraft are centrally monitored and managed so that, for example, system-related defects in the boards that occur during use can be detected at an early stage and eliminated via remote or on-site maintenance updates, thus ensuring largely trouble-free operation.

[0029] According to the system presented, a large number of watercraft are provided by the central office. Rentals are essentially initiated through the central office, and the fleet base essentially only provides the premises for the fleet, issues the watercraft to the user / renter, familiarizes them with the selected watercraft, and takes the watercraft back after use. Information regarding the use of the respective watercraft can also be transmitted directly from the central office to the mobile customer interface. The fleet base also handles, for example, manual care and maintenance of the watercraft, the installation of spare parts, and the charging and maintenance of battery units.

[0030] The connection of the watercraft, each equipped with a sensor system, to the central platform (e.g. a cloud server) via the communication network also makes it possible for the central station to control the watercraft if its use does not comply with the specifications or if control via the user is no longer possible due to a defect.

[0031] The sensor system mentioned is not necessarily integrated into the respective watercraft, but can also be used as an external unit, which then preferably contains the actual sensors and also the communication module, etc.

[0032] In one embodiment of the system, the central office provides a fleet interface (B2B) designed to supply the fleet base with the key data and information required for the rental and use of the vessel via the communications network. This fleet interface can be implemented, for example, as an app integrated into a mobile phone or as a computer / desktop computer. The information content and any rights granted to the fleet base can vary depending on the type of interface.

[0033] The service for the user / customer is optimized if the customer interface or its software is designed to receive information about the route / route (ride analysis) of the rented watercraft via the communication network operated by the head office.

[0034] In a particularly preferred embodiment, the watercraft is equipped with a display for displaying functional parameters, weather data, communications, and predetermined thresholds, such as a geofence, so that the user can be easily informed via the control center or, if necessary, the fleet base. The display can be integrated into the watercraft and / or implemented as an external device, e.g., augmented reality glasses.

[0035] Advantageously, the propulsion unit of the watercraft is further designed so that it can be controlled independently of the user via the communications network. This makes it possible to automatically hold the watercraft in a position, for example, in the event of a fall or the like, or to return it to a predetermined position, for example, toward the user. As indicated above, the fleet base or control center can, for example, enter the navigable area on a map (geofence), which is displayed, for example, via the display and / or augmented reality glasses or the like.If the vessel then approaches a limit of its operating range, the vessel's speed can be initially reduced via the communication network with the central platform and the control center. This external intervention alerts the user that they are approaching a limit of their operating range and must turn away. If the user does not react, the vessel can be stopped or turned around. This is important for safety reasons (rocks, shallows, currents) and regulatory reasons (swimmer zone, vessel zone) to improve the acceptance of an inventive system among users and authorities.

[0036] Support for the fleet base is further optimized when a replacement or service, such as remote maintenance of watercraft, is carried out via the central office based on the watercraft's functional parameters recorded via the communications network. This ensures that the fleet base always has a sufficient number of fully functional, updated watercraft (predictive maintenance). This update can also affect the on-board computer software and thus the drive control system. Remote maintenance is preferably carried out via over-the-air updates (OTA updates) via the central office. Such a watercraft can be, for example, a jetboard, an eFoil, an eBike (electric water bike), an underwater scooter, an eSUP, an e-bodyboard (preferably designed for prone use), or a solar kayak. Jet skis and similar devices are also included under the term "watercraft."As explained above, it is preferred if the aforementioned functionalities (e.g., sensors or the ability to control the watercraft via the control center) are integrated into the respective watercraft. In principle, third-party vehicles, such as those already present at the fleet base, can also be upgraded by installing an external unit (IoT box) on the vehicles that at least takes over the function of the integrated sensors. This can also be done without the possibility of interfering with the control of the third-party vehicle's drive. The inventive concept does not necessarily require electrically or otherwise motor-driven watercraft. For example, it is also possible to equip conventional non-motor-driven sports equipment, such as SUPs, with an IoT box and then manage it via the fleet base.

[0037] The operational safety of the fleet is further improved if each vessel is assigned a life jacket with sensors / trackers that can be detected, for example, via the customer network, GPS or radio, especially mobile communications, so that the life jacket allows the user to be located.

[0038] As already mentioned, it is preferable if the fleet's vessels are owned by the headquarters.

[0039] Preferably, the number of watercraft, in particular jetboards, offered for rental by the fleet base headquarters is variable depending on demand, so that it is ensured that the fleet base does not have too few or too many watercraft available.

[0040] The system therefore requires a central office with a large number of electrically powered watercraft. A fleet of these watercraft, i.e., a subset of the watercraft owned by the central office, is made available to a fleet base for use. The term "fleet base" encompasses individual rental stations or the stations of a holiday club with multiple locations. Each watercraft is equipped with an on-board computer to control the watercraft's propulsion, as well as sensors that measure functional parameters such as the charge level of a drive battery unit, the position of the watercraft, the driving status (speed, acceleration, cornering, user load, etc.).as well as service intervals and a vessel identifier) ​​can be recorded and transmitted to a central platform via a communications network, enabling detailed fleet monitoring. The system operated using this method also requires a customer interface, preferably a mobile one. The system is operated using the following steps, which do not necessarily have to be performed in the order presented here.

[0041] First, as mentioned above, the central office provides a large number of watercraft to the fleet base. These watercraft are integrated into a communications network in such a way that the central office can evaluate the functional parameters recorded by the sensors as well as control signals from the watercraft's on-board computer. The user books a watercraft offered by the central office or the fleet base via the customer interface at the central office. The fleet base then receives corresponding notification of the booking, allowing the fleet base to hand over the watercraft to the user and provide the user with further training. The user concludes a rental agreement with the fleet base, which is also responsible for the payment of local VAT.

[0042] After the rental period has expired, the watercraft will be taken back by the fleet base so that it can be made available for the next rental – possibly after servicing. Preferably, the rental board will be activated via the central office and locked after use to prevent any unauthorized use of the watercraft. While the user is using the watercraft, the watercraft's functional data and the on-board computer's control signals are monitored and, if necessary, functional and / or geographical limit values ​​are set via the communications network by the central office. This ensures safe use of the watercraft according to the criteria specified by the central office and / or the fleet base.

[0043] For example, functional and / or geographical limits (geo-fences) can be specified and monitored by the central office and / or the fleet base. Suitable apps should preferably be provided to allow authorized personnel to specify or monitor such limits with minimal effort.

[0044] In the event that specified functional and / or geographical limits are exceeded or there is a malfunction of the vessel, the control center can intervene in the control of the vessel via the communication network and the central platform, so that any danger to the user is virtually eliminated.

[0045] According to one embodiment of the invention, the central office for the user placement receives a portion of the rental fees from the fleet base as commission.

[0046] The customer interface can be designed in such a way that certain discounts are granted if a user books a board multiple times.

[0047] Additionally or alternatively, a coupon code function can also be provided to grant customers benefits within the scope of marketing campaigns or the like. The user can then book a board at a discounted rate or even free of charge by entering the code, or allow third parties to use the board via the code. In one embodiment of the invention, the customer interface is designed so that the user can tip the fleet base or a fleet base employee.

[0048] As explained, the customer interface can be implemented, for example, through a mobile app, a desktop app or a website.

[0049] Preferred embodiments of the invention are explained in more detail below with reference to schematic drawings. They show:

[0051] Figure 2a is a schematic representation of a fleet of watercraft managed by means of the system and method according to the invention;

[0052] Figure 2b shows a watercraft designed as a surfboard / jetboard from a fleet from Figure 2a;

[0053] Figure 3 shows a schematic diagram of the IoT technology implemented in the system;

[0056] Figures 6a to 6f show mockups of a B2B desktop app and Figures 7 and 8 show mockups of additional functions of a B2C customer interface, in particular a B2C mobile app.

[0057] In the system S shown in Figure 1 for managing a watercraft fleet, a central unit 1 has a plurality of watercraft 2, for example, jetboards or eSUPs—hereinafter referred to as boards 2—some of which are made available as a fleet 4 to a fleet base 6, for example, a rental station near the coast. The central unit 1 does not have to be implemented as a physical unit, but can consist of several units that are physically or virtually interconnected to form the central unit 1.

[0058] As explained, in the system S, the boards 2 are made available by the central office 1 to the fleet base 6 for use / rental free of charge or against payment of a basic fee, whereby they remain the property of the central office 1.

[0059] As indicated in Figure 1, several fleet bases 6, 6' 6", ... can be supplied with a fleet 4 of boards 2 via the central unit 1, whereby the fleet size depends on the respective requirements. As will be explained in more detail below, the boards 2 as well as the central unit 1 and the fleet base 6 as well as other units of the management system S are combined in the manner of an IoT system 8, whereby communication between the central unit 1 of the management system, the fleet bases 6 and the boards 2 and the other units takes place via a communication network 10 and a central platform 11 (server). As explained, the fleet base 6 can also be formed by the stations of a holiday club at several locations.

[0060] In the illustration according to Figure 1, the actions of the parties involved (headquarters 1, fleet base 6 and user 12) are shown with solid lines, with the actual communication / data connection for implementing the actions taking place via the communication network 10 indicated by dashed lines and the central platform 11. If a customer / user 12 now wishes to rent one of the boards 2 from a predetermined fleet base 6, they can access the IoT system 8, in particular the communication network 10, to a limited extent via a suitable customer interface 14, for example a mobile phone on which a B2C app provided by the headquarter 1 is installed or a website accessed via a desktop computer, a tablet, a mobile phone or the like.Using this app or the website (the following essentially only discusses the app, but its functions can also be implemented via the website), the user 12 can find out whether and at what time boards 2 are available at a specific fleet base 6 and can accordingly book a board 2 for a predetermined period of time. In one embodiment of the invention, the user 12 can choose between different driving modes. For example, selecting an "Advanced" mode allows surfing up to a speed of 25 km / h, while in a "Cruise" mode the maximum speed is limited to 15 km / h, for example.

[0061] When using the jetboard as an eSUP, propulsion is achieved - as explained in more detail below - by thrust support from the drive (so-called Padelec), whereby the maximum speed can be limited to 8 km / h.

[0062] The contact details of user 12 are stored in the system via the B2C app, allowing for cashless payment after booking confirmation. This payment is preferably made to fleet base 6, with which user 12 concludes a rental agreement. Fleet base 6 is then also responsible for the payment of local sales tax, if applicable. User 12 then receives information from headquarters 1 or from fleet base 6 via their customer interface 14 that the booked board 2 is ready and can be picked up by user 12. The IoT system 8 ensures that only fully functional, updated, and charged boards 2 are made available via fleet base 6. Furthermore, information about board 2 and the terms of use can be provided to user 12 via the customer interface 14.After receipt of payment, Head Office 1 receives a share of the collected rental fee from Fleet Base 6. The remaining portion of the rental fee at Fleet Base 6 essentially covers the handling of Boards 2 from Fleet 4 during handover to User 12 (pick-up) and the return of Boards 2 after use, as well as the aforementioned service activities for Boards 2. This means that Fleet Base 6 can generate significant revenue / profit from the rental with minimal investment (Boards 2 are provided free of charge or for a fee that is small compared to the purchase price by Head Office 1).

[0063] User 12 then takes over the reserved board 2 at the selected fleet base 6, with the board 2 being activated via the central office 1 during the pick-up. Furthermore, user 12 receives instructions on how to operate the board 2 and the specific characteristics of the respective area in which the board 2 is to be operated.

[0064] The software installed on the customer interface 14 can also be configured to grant certain discounts for multiple bookings of a board 2. A coupon code function (see Figure 8) can also be set up to grant customers certain benefits as part of marketing campaigns. User 12 can then, by entering the code, book a board 2 at a discounted rate or even free of charge, or allow third parties, such as their customers, to use the board 2.

[0065] After activation and initiation, the user 12 can use the board 2 in the predetermined usage area, as shown in Figure 1 top left, whereby the actual position - as explained in more detail below - is recorded via the IoT system 8 and the sensors integrated in the board 2.

[0066] For communication between the central office 1 and the fleet base 6, the central office 1 can provide a B2B interface 15, which is also implemented with predetermined software that facilitates the management of the fleet 4 and the communication between the central office 1 and the fleet base 6. The software of the B2B interface 15 is designed so that the central office 1 can also provide technical support / service for the boards 2.

[0067] It is preferred for the head office 1 to offer at least two different B2B interfaces 15. The first B2B interface 15 is based on an app, which is installed, for example, on a mobile phone or the like. This app is then used directly on site and displays the bookings and sales for the day. It is used for user check-in, for example by scanning a QR code assigned by the head office or using a digital ticket generated during booking via the B2B interface for check-in and handover to the customer. This app can also be used to record the customer's ID, damage during check-out, etc. Furthermore, booking times can be changed and the watercraft currently in use can be displayed on a virtual map.

[0068] Furthermore, this app can be used to display appropriate notifications in the event of security problems (defective vehicles, exceeded rental periods, geo-fence breaks) so that Fleet Base 6 employees can respond accordingly.

[0069] Alternatively, the B2B interface can also be implemented as a web or desktop version. This essentially has the same functionality as the aforementioned B2B app and also enables sales / finance analysis. Furthermore, this interface provides a web shop for ordering spare parts for the watercraft, particularly the boards 2. Other extensions to this desktop version include merchandise and marketing packages, with the option to define rental prices and, if necessary, activate dynamic pricing. Furthermore, this desktop version can be used to define station permissions (particularly for fleet-based rental station chains) and employee permissions (who is allowed to see what?). The B2B interface, especially the website of the desktop version, is preferably designed to record opening hours so that these can be offered to the user 12 when booking.Due to the integration of the respective boards 2 into the IoT system 8, fleet monitoring can be carried out via the control center 1 and / or the fleet base 6, so that, for example, the user 12 can be provided with detailed information about the route, driving speeds, angular velocities, etc. of the board 2 via the customer interface 14, so that even after returning the board 2 to the fleet base 6, the user receives detailed information about its use and can share this information, for example, with third parties on social media.

[0070] Due to the embedding of the boards 2 in the IoT system 8, the control center 1 (and possibly also the fleet base 6) is always informed about the status of the board 2, so that any damage / malfunctions can be remedied immediately by replacement, software update or service.

[0071] As mentioned above, the activation of the board 2 can be part of an end-to-end handover process, in which the user 12 books a board 2 via the customer interface 12 (e.g., the B2C app), generating a ticket that is then used in the B2B interface 15, 15' for the check-in of the user 12 and the handover of the board 2 at the fleet base 6. The applicant reserves the right to make an independent claim to this process.

[0072] The IoT system 8 used in the management system S is explained with reference to Figures 2a, 2b, which show a board 2 designed as an eSUP (Figure 2a) or Surf-ZJetboard (Figure 2b).

[0073] Figure 2a shows a schematic diagram of the fleet 4 of watercraft 2, 2a, 2b, 2c, which, in the manner of an IoT system 8, are connected via the communication network 10 to a central platform 11. This platform can be hosted either locally, as a server network, or in a cloud (cloud computing platform). This central platform 11 provides a scalable and flexible infrastructure for storing and processing the data explained in more detail below. The network protocols can be partially wired or wireless, such as Ethernet, Wi-Fi, Bluetooth, ZigBee, or LoRaWAN, with data transmission being able to occur continuously or periodically depending on demand and bandwidth. Communication between components of the board 2 can also occur via an NFC protocol, in which case these components are implemented with NFC chips.

[0074] In the illustrated embodiment, the central platform 11 is also in data communication via the communications network 10 with at least one fleet base 6, which issues, in particular leases, the boards 2 of the fleet 4 to users 12. In the illustrated embodiment, only one fleet base 6 is shown—in principle, of course, several fleet bases 6 can also be in data communication with each other via the central platform 11 and the communications network 10.

[0075] In the illustrated embodiment, the central administration of the fleet 4 is provided via the control center 1, which is also part of the IoT system 8 via the communication network 10 and the central platform 11.

[0076] As mentioned above, the board 2 can be designed as an eSUP board, where the user 12 uses a propulsion tool, such as a paddle 16, to propel themselves through the water 7. As indicated in Figure 2a, top right, and in Figure 2b, the fleet can of course also be designed as a surf jetboard. It is also possible to design it as an eFoil or as an underwater scooter, so that the fleet 4 accordingly consists of a multitude of different boards 2, all of which are managed / administered via the central unit 1 in the manner described above. The respective geometries of the boards 2 are adapted to the intended use.

[0077] According to the embodiment shown in Figure 2a, the boards 2 are designed with a board body 18 constructed in the manner of a hardboard, which is at least partially surrounded by a shock absorber 20 made of an inflatable drop-stitch material. The shock absorber 20 is connected to the board body 18 made of sandwich material in a force-fitting and / or form-fitting manner and, to improve operational safety, can be designed with two air chambers 22, 24 (indicated by dashed lines) that can be inflated independently of one another, thus ensuring buoyancy even if one air chamber 22 or 24 leaks.An electric drive unit 26 is arranged in the board body 18, which can be designed as a water jet drive with a radial pump and an output-side compressor screw, via which a water jet 28 is ejected through an output Z pressure channel 30, so that the board 2 is moved in the direction of its longitudinal axis (direction of travel) with the aid of this water jet drive 26.

[0078] The drive unit 28 is preferably designed with an EMS (Engine Management System) which, for example, via CAN protocols, is in data communication connection with the IoT system 8 and also with a BMS of a battery unit 36 ​​described below, so that both components can be controlled centrally and software and firmware updates can also be carried out.

[0079] In order to maneuver the board 2 into a curve using only the electric drive unit 26, particularly during slow travel of, for example, 2 km / h, two transverse thrusters 32, 34 (indicated by dashed lines) are preferably provided. These thrusters are configured in an approximately X-shaped manner on the underside (underwater hull) of the board 2 on a transverse thruster console. These two transverse thrusters 32, 34 are arranged, for example, so that they push forward and backward in directions of 45°, 225°, and 315°, 135°. Both transverse thrusters 32, 34 can be configured, for example, with an impeller. Such a system is capable of rotating the board 2 approximately on its central axis, moving it forward and backward, or even pushing it sideways parallel to the direction of travel.The thrust required by the drive unit 26 is low when traveling slowly, so that the maneuvers can be performed with little energy expenditure without the need for assistance from the user 12.

[0080] The electric drive unit 26 is powered by a battery / accumulator unit 36, also integrated into the board body 18 and indicated by dashed lines. This battery unit 36 ​​is positioned beneath a cover so that it can be easily replaced. In the illustrated embodiment, this battery unit 36 ​​is positioned approximately in the same area as the user 12, ensuring balanced weight distribution.

[0081] In the field of vision of the user 12, a display 38 is formed in the board body 18, on which essential data, such as the local position, the driving speed, the remaining battery capacity, an identifier, etc. can be read.

[0082] In the illustrated embodiment, the display 38 is controlled via an IoT board 40—also called an IoT box—of an on-board computer 42, on which the IoT devices / sensors, etc. required for use are implemented. This IoT board 40 is connected via the communications network 10 to the central platform 11 and thus also to the control center 1 and the fleet base 6. The drive unit 26 and the battery unit 36 ​​are controlled in a conventional manner via the on-board computer 42, which is also integrated into the IoT network. Such on-board computers 42 are also used in boards 2 / fleets 4 that are not implemented as IoT systems 8.

[0083] The paddle 16 used in the eSUP is designed in a conventional manner with a shaft 44, to the board-side end section of which a blade 46 is attached, which - as is usual with SUP paddles - is angled relative to the shaft 44 toward the bow of the board 2. The shaft 44 can be designed to be adjustable in length to adapt to the body size of the user 12. At the end section of the shaft 44 remote from the blade 46, a handle knob 50 is provided, which is gripped by a hand 52 of the user 12. In the area of ​​this handle knob 50, an adjusting device 54 is arranged on the shaft 44, via which a direction of travel and thrust assistance can be adjusted by means of the electric drive unit 26. This adjusting device 54 is positioned such that it can be operated by the hand 52, in particular by the thumb 56 of the user 12, without releasing the handle knob 50.As explained in the applicant's parallel application, the blade 46 incorporates a sensor system (not shown in Figure 1), which may be implemented, for example, with a bending sensor, a temperature sensor, and / or a humidity sensor. The paddle 16 is further configured with a communications module 58, which has a data connection / radio connection 60 with the on-board computer 42 of the electric drive unit 26, so that the control signals generated by the actuating device 54 and the sensor system of the blade 46 are detected via the on-board computer 42, so that the electric drive unit 26 is controlled in accordance with these control signals.

[0084] As explained in the parallel application, the bending sensor is integrated into the blade 46 or the shaft 44 in such a way that, after the blade 46 is submerged in the water, the changes in shape caused by paddling on the push-off surface and inside the blade 46 are registered and reported to the on-board computer 42. Depending on the intensity and direction of the paddling movement, this then converts the degree of deformation into a forward or reverse thrust of the drive unit 26. In this way, it is possible to receive only slight thrust assistance during light paddling, while during more intensive paddling, a stronger thrust assistance from the drive unit 26 is specified via the on-board computer 42.

[0085] The humidity sensor and the temperature sensor reliably detect the immersion of the blade 46 into the water 7, with both sensors operating redundantly. Only when both sensors simultaneously reach a certain signal value is this considered confirmation that the paddle is in the water – only in this case is the evaluation of the bend sensor signals and thus the thrust support activated.

[0086] In principle, the signals detected by the sensors of the paddle 16 can also be reported directly to the central platform 11 via the communication network 10, so that the drive unit 26 or the battery unit 36 ​​is then controlled via the IoT system 8. In principle, however, this control can also be implemented as a support or backup to the usual control via the on-board computer 42. As explained, the board 2 shown large in Figure 2a with the paddle 16 is designed for use as an eSUP. If the board 2, as shown in Figure 2b, is to be used like a surfboard or an eFoil or underwater scooter, no paddle 16 is required. The drive unit 26 and / or the battery unit 36 ​​are then controlled in a manner known per se (see the prior art described above) via handheld devices worn by the user 12, for example a smartwatch or the like.Alternatively, according to Figure 2b, a handle 62 can also be used, which can be designed with a communication module 58' and an actuating device 54' to control the drive unit 26 through appropriate actuation and thus select the propulsion and direction of travel. It is particularly preferred if the handle 62 is attached to the bow 48 of the board 2 via a rope 64 or a cable, so that the user 12 can support themselves on the board 2 via the handle 62 while surfing, thus improving driving stability compared to a solution in which the drive unit 26 is controlled via a smartwatch or the like.

[0087] Conversion from an eSUP to a surfboard can be accomplished simply by exchanging the paddle 16 for the handle 62. A corresponding input is made on the on-board computer 42 or this conversion is automatically recorded via the IoT system 8. In principle, it is also possible to carry such a paddle 16 for emergency use, so that the user 12 can return to the fleet base 6 under their own power in the event of a propulsion failure.

[0088] The handle 62 and the paddle 16 are each provided with a power supply, for example a small battery or the like, which can be charged via the drive unit 26 or the battery unit 36.

[0089] In a preferred embodiment, the display 38 is designed as an ePaper display, which is very energy-efficient and only consumes power when the image shown on the display 38 changes. Good readability is guaranteed even in bright sunlight, since these ePaper displays essentially do not emit light to display images but rather reflect the light - similar to real paper. In the illustrated embodiment, the display 38 is designed such that, for example, the charge level of the battery unit 36, the remaining travel time, the date, the time, the GPS position, weather data or other sensor signals can be displayed, so that the user 12 receives a real-time overview of the current driving situation. In principle, it is also possible to display a conversation with other users or the fleet base 6 via the display 38.

[0090] In the embodiment shown in Figure 2a, the IoT board 40 is further configured with a sensor system 66, which in the specific embodiment comprises a GPS sensor 68, an IMU (Inertial Measurement Unit) 70, a temperature sensor 72, a pressure sensor 74, and a humidity sensor (not shown), whose signals are connected to the central platform 11 via the communication network 10. As stated above, the communication network 10, i.e., the specific connection to the central platform 11 (server), can be established via a mobile radio standard, for example, GSM (Global System for Mobile Communication). Alternatively, the data connection can also be established via various network protocols, partially wired or wirelessly (see above).

[0091] Such a communication network 10 (in particular GSM) enables real-time transmission of the acquired data to the central platform 11, which receives this data from the sensor system 66 (IoT devices) and stores it in a database or the like. Various operations can then be performed via the central platform 11 to analyze, filter, aggregate, transform, or clean this stored data. This data processing can occur in real time or with a delay, with the central platform 11 then presenting the processed data in a suitable form to make it usable for the user 12 or the sensor system 66. Depending on the result of this evaluation, the central platform 11 or the user 12 can then react to the preferably visualized data by triggering or adapting actions centrally or by the user 12 that affect the board 2 or other systems.This enables remote diagnosis of the respective boards 2, and also makes installing software updates, etc., extremely easy, thus ensuring optimized performance of the boards 2. The GPS sensor 68 enables the movement of the board 2 and its geographical position to be tracked in real time. This allows users 12 to map their routes and, for example, record speed and acceleration. In an emergency, it is also possible to easily locate the board 2 if the user 12 is separated from the board 2. As explained above, the IoT system 8 also enables the definition of virtual boundary areas (geo-fencing), which, when exceeded, alert the user 12 that they have strayed too far from a predetermined area.

[0092] The IMU 70 can accurately measure the board's speed, orientation, and gravitational forces acting on the board 2, for example, using a combination of acceleration sensors, gyroscopes, and magnetometers. Performance metrics for the user 12 can also be derived from this data, allowing the appropriate evaluation of this data to improve or train the user's maneuvering skills and balance. All of these measures contribute to increased safety when using the board 2, with unusual movements that could lead to a collision or fall being detected in a timely manner using the IMU 70.

[0093] The temperature sensor 72, controlled via the IoT board 40, is positioned so that it can measure both the ambient temperature and the temperature of the board 2 itself. Accordingly, useful information about the water condition can be read from the signals of the sensor 72. Furthermore, overheating of the electronic board components can be reliably detected and thus prevented using the temperature sensor 72. The aforementioned humidity sensor can, for example, detect whether the board 2 is in contact with water, so that cracks, for example, can be detected. In principle, a humidity sensor can also be used to measure the humidity in the area of ​​the battery unit 36 ​​or the drive unit 26 and thus be part of the BMS or EMS.

[0094] The pressure sensor 74 is designed to detect the water pressure around the board 2 so that the immersion depth of the board 2 can be detected, particularly when surfing or performing moves - from this data, the wave size and the power of the wave can then be detected so that the users 12 (surfers) can better anticipate their moves.

[0095] The basic structure of the IoT system 4 implemented in the previously described board 2 or in the fleet 4 is explained again with reference to Figure 3. As explained above, in the described embodiments, each board 2 of the fleet 4 has a temperature sensor 72, a pressure sensor 74, and an IMU 70, each designed as an IoT device. The parameters detected by this sensor system 66, for example, the temperature, pressure, and movement parameters, can be displayed directly on the display 38 or transmitted via the communication network 10, for example, a GSM (represented in Figure 3 by a cell phone tower 76), to the central platform 11, for example, a server. This central platform 11 receives—as explained above—the data from the sensor system 66 and the other IoT devices and stores it in a database.As explained, these data can then be processed by the central platform 11 in real time, so that depending on these data, corresponding information is shown on the display 38 or on the customer terminal 14 or an intervention in the control of the drive unit 26 takes place, whereby this correspondingly corrects or overlays the control data specified by the user 12 on the actuating device 54, 54'.

[0096] The position of the board 2 is detected via the GPS sensor 68 and the GPS system or a corresponding satellite navigation system.

[0097] In principle, it is possible to manage other vehicles, such as land vehicles, as part of the fleet using the described procedure or system S.

[0098] The basic functions of the software installed on the customer interfaces 14, the B2B interfaces 15, and its desktop version 15 are described below using mockups of the respective apps. Such a mockup can be understood as a type of screenshot illustrating the basic structure of the respective app, with some of the mockups described below using placeholders for text and images.

[0099] Figure group 4 (Figure 4a to Figure 4i) relates to the basic structure of the B2C mobile app, hereinafter referred to as the "B2C app." This is designed to be installed, in particular, on smartphones, tablets, or similar devices with common operating systems, with the download preferably taking place via the respective app store. After this download, the user is first asked, as shown in Figure 4a, to register or, if already registered, to log in. This is usually done by entering a username and / or password. During this registration, payment methods are preferably also specified, via which the fees associated with renting a board 2 are debited. As explained above, the actual booking process is essentially handled via the central office 1, and payment is made to the fleet base 6.With such a registration, the user 12 can also enter a profile that allows, for example, the central office 1 or the fleet base 6 to make suggestions to the user 12 for a board 2 to be rented depending on the wind and wave conditions.

[0100] When using the B2C app, user 12 further agrees to have their location 78 recorded so that suggestions for the nearest fleet bases 6a, 6b, 6c can be made, as shown in Figure 4b. User 12's location 78 is also displayed, making orientation easier. The app is also designed so that user 12 can preselect a desired fleet base 6 independently of location 78, allowing, for example, a reservation for an upcoming period (weekend, vacation, etc.).

[0101] Depending on the selection of the fleet base 6, the user 12 receives information according to Figure 4c about the boards 2a, 2b, 2c, ... available at the selected time, wherein these boards are, for example, divided into different categories that take into account the riding ability and expectations of the user 12. In the embodiment according to Figure 4c, for example, it is announced that an eSUP (Padelec) described in Figure 2a will be available in the near future, but that at the desired time only one board type with limited speed (Cruise) and one board type with maximum speed (Advanced) are available. It can be provided that booking the latter board type is only possible with the appropriate qualifications of the user 12.

[0102] According to Figure 4d, the desired rental times (time slots) can then be selected for the appointment, whereby different rental fees can be assigned to these.

[0103] After this preselection, user 12 then makes the booking and payment, which goes directly to the fleet base 6. User 12 then receives the booking confirmation from the central office 1, which can be executed, for example, as shown in Figure 4e. As explained above, the booking and payment can also generate a digital ticket, which can then be used via the B2B interface 15, 15' for check-in and handover of the board 2 to user 12.

[0104] The B2C app also includes an overview as shown in Figure 4f, from which the future bookings and past bookings, as well as any canceled bookings, of user 12 can be seen. This overview also shows the favorite boards 2 and, if applicable, the routes traveled in the past, similar to a "road book."

[0105] Check-in can then also be initiated on-site via this page, whereby proof of the booking can be provided to the respective Fleet Base 6.

[0106] For this purpose, as shown in Figure 4g, a QR code 80 can be issued from the central unit 1 to the user 12, which is then read at the fleet base 6. After returning the board 2 to the fleet base 6, the user 12 can then retrieve "ride statistics" as shown in Figure 4h via the B2C app. These statistics include, for example, the distance traveled, the average speed, the number of waves ridden / surfed, and the coordinates of the route. This information can be shared with other users 12 or on social media. User 12 can also evaluate the ride.

[0107] In a preferred embodiment, the B2C app is designed such that the user 12 receives a message about the upcoming ride in good time before the scheduled start of the rental.

[0108] As shown in Figure 4i, the essential user data is compiled in an overview, displaying the number of rides and a rating of these rides. This rating can be influenced by the user (12) themselves, but in principle, it is also possible to rate the respective ride in the app based on certain criteria, such as the number of moves, cornering speeds, number of waves, maximum speed, average speed, etc. This overview also contains the aforementioned information about pending bookings, the favorite fleet bases (6), the history of past rides, and the profile of user (12), which can be adapted to current developments as needed.

[0109] Accordingly, this B2C app is designed to encourage the user 12 to use the boards 2 and to share his rides with third parties and motivate them to use the system S.

[0110] Communication between Headquarters 1 and Fleet Bases 6 preferably takes place via the B2B interface 15 described below (hereinafter referred to as the "B2B app") or its desktop version 15'. The essential functions of the B2B app are explained using Figure Group 5 (Figures 5a to 5k). This B2B app is only accessible to registered Fleet Bases 6 and their authorized employees and can therefore only be downloaded with the consent of Headquarters 1. As is generally customary, in order to use this B2B app, Fleet Base 6 is required to register prior to use and to grant Headquarters 1 the access rights associated with such use to relevant information, as well as to enable communication with Users 12 via the B2B app.Through this registration, Fleet Base 6 is integrated into the Marketing-ZBusiness concept of Head Office 1 and can therefore be booked by the respective users 12 via the B2C app described above, whereby - as mentioned - the booking and payment are made via Head Office 1.

[0111] Fleet Base 6, which communicates with Head Office 1, receives an overview of the bookings made by users 12 with the relevant Fleet Base 6 via the B2B app as shown in Figure 5a. Similarly, Fleet Base 6 also receives information about any canceled bookings, so that Fleet Base 6 has sufficient time to respond accordingly. This overview also includes information about users 12 who are already traveling with boards 2 rented from Fleet Base 6.

[0112] Based on this overview, Fleet Base 6 is informed about upcoming bookings and can retrieve details about the respective booking via the B2B app (see Figure 5b) before handing over the board 2 to User 12. Accordingly, Fleet Base 6 receives information about User 12, the selected usage mode (Padelec, Cruise, Advanced), as well as the payment method and the payment made. Fleet Base 6 can also retrieve the booking history for the respective User 12 to facilitate the response to individual requests.

[0113] As shown in Figure 5c, the fleet base 6 can then receive a recommendation from the central office 1 for a board 2 to be used and a suitable battery, ensuring that the board is provided according to the customer's (user 12's) requirements. After the user 12 arrives at the fleet base 6, the identity (ID) of the user 12 is verified according to the mockup shown in Figure 5d. After confirming the identity, a QR code 80 of the selected board 2 is scanned, followed by the QR code 80 of the user 12 shown in Figure 4g, which the user received from the central office 1 via the B2C app.

[0114] In a next step, the fleet base 6 then receives confirmation that the board 2 in question is linked to the system of the fleet base 6 and the central office 1 and the associated data of the user 12, so that access to this board 2 in question is excluded for third parties.

[0115] After these steps, the actual physical handover of the board 2 to the user 12 takes place, where the user 12 receives further instructions via the B2C app and, if necessary, in person, such as the wearing of a life jacket, the exact start time of the rental period, special features of the area, etc. This information is sent to the user 12, for example, in the form of a text message and displayed on the B2C app and the display 38.

[0116] In a preferred embodiment, the B2B app allows the fleet base 6 to edit the booking time arranged via the central office 1, provided the booking situation permits. For example, it is possible to slightly postpone, shorten, or extend the actual booking time compared to the originally selected time. This naturally results in a corresponding adjustment of the rental fees, which is then processed via the central office 1. Such a procedure is illustrated in Figure 5e.

[0117] Another option for customizing the rental conditions is shown in Figure 5f, which allows for cancellation of the rental transaction due to external circumstances. These can include, for example, inaccessibility of the beach, a closed rental station, a request from User 12, the listing of User 12 on a "blacklist," technical circumstances (e.g., battery failure), or other reasons such as User 12's lateness or non-appearance, or unfavorable weather and wave conditions.

[0118] As already mentioned above, information about the ongoing use of the boards 2 already issued by the fleet base 6 can also be retrieved via the B2B app, so that both the central office 1 and the fleet base 6 are informed about the respective use. As explained above, the boards 2 are designed with a sensor system 66 and with communication modules 58, which make it possible to record the current position and driving status of the board 2 at any time and to report this to the central office 1 and the respective fleet base 6 via the previously described communication network 10. This means that life tracking of all boards 2a, 2b, 2c, ... in use takes place, which can be visualized, for example, in the manner shown in Figure 5g. This illustration also shows a geo-fence 82, which marks the driving area usable by the users 12 or their boards 2.If this geo-fence 82 is exceeded, corresponding information can be issued to the respective user 12, for example via the display 38, so that they are actively requested to return to the approved area. In the event that the user 12 does not respond to this request, the drive unit 26 of the board 2 can be controlled via the fleet base 6 or the control center 1 so that the board 2 is returned to the usable area. Alternatively or additionally, the drive 26 can also be controlled in such a way that driving out of the geo-fence 82 is not possible. The independent / autonomous return of the boards 2 is also advantageous in an emergency, for example if a user 12 is no longer able to actively return the board 2. By appropriately controlling the drive units 26, a collision between the boards 2 or with obstacles within the geo-fence 82 can also be prevented.

[0119] The Geo-Fence 82 can be specified via the control center 1 or via the fleet base 6, or it can be individually adapted to current developments, such as a regatta in the area of ​​the Geo-Fence 82 or unusual weather conditions (storms, waves) – this will be discussed further below. As shown in Figure 5h, the charge level of the respective battery units 36 can also be checked via the B2B app, so that a corresponding signal can be sent to the user 12, prompting them to return to the fleet base 6 when the battery unit 36 ​​is at a corresponding charge level.

[0120] The aforementioned "life tracking" enables the fleet base 6 and the control center 1 to retrieve and record details about the respective use of the board 2 or the riding behavior of the user 12, so that this user or a group of users 12 can access detailed information about their ride. This information can also be shown online on the display 38. Of course, other safety-relevant information, such as a decrease in air pressure in the board 2, problems with the drive unit 26, etc., can also be communicated via this display 38, thus minimizing the risk potential for the user 12.

[0121] When returning the board 2, the QR code 80 of the board 2 is again scanned as shown in Figure 5i. This is then checked for damage via the sensor system 66 and also visually, with documentation by means of images or the like being provided if necessary.

[0122] The user 12 can then receive an evaluation from the fleet base 6 or the head office 1, which may be taken into account positively or negatively in future rentals.

[0123] After completion of this check, the return of board 2 will be confirmed, if applicable, and the head office 1 will then transmit information about any necessary maintenance measures, such as charging the battery (unit 36), etc., to the fleet base 6 via the B2B app.

[0124] In one embodiment of the B2B app, it contains information accessible only to a limited group of employees about the expected rental transactions for the current day and in the past, and possibly also in the future. Such an overview is shown as an example in Figure 5j. For example, the rental income of Fleet Base 6 within certain time periods, the forecast for the total rental income for the day, capacity utilization, the availability of Boards 2, and, if applicable, a comparison with possible specifications / competitors are displayed, so that Fleet Base 6 is up-to-date about the respective rental situation.

[0125] As explained above, the geo-fence 82 according to Figure 5k can be set up via the fleet base 6 or via the central office 1. This can be done in the manner of route planning on a map integrated into the B2B app. However, taking local and temporal peculiarities into account is easier if the geo-fence 82 is set up on site. For this purpose, for example, a boat or jet ski equipped with a GPS or even a board 2 can be used, the driver of which carries a device with the B2B app and first drives to a starting point located in the geo-fence 82 to be set up. Upon reaching this starting point, "Start" is pressed on the B2B app and the course of the desired geo-fence 82 is followed and then "Stop" is pressed, so that the geo-fence 82 is saved accordingly on the B2B app and thus also on the central platform 11.If additional zones are to be excluded within this Geo-Fence 82, such as shallow-draft areas or protected areas, these can be defined with a further survey, and access can be regulated accordingly. As mentioned, this Geo-Fence 82 can be individually adjusted to current conditions, although this adjustment is only possible by a limited group of people with appropriate access authorization.

[0126] The functions of the B2B desktop app are explained below using Figure 6 (Figures 6a to 6f). As with the apps described above, each user must create an account to use the B2B desktop app. The respective authorizations must be confirmed by Headquarters 1 or an authorized employee at Fleet Base 6.

[0127] The B2B desktop app is designed for use with common operating systems (e.g., iOS, Windows), with a range of functions that is at least equivalent to that of the previously described B2B app and allows for additional evaluations.

[0128] Figure 6a shows the home page of the B2B desktop app with the main menu, which can be used to control the respective functions. This home page also displays essential information, such as the bookings expected for the current day, the realized and predicted sales, the life tracking of the used boards 2a, 2b, 2c, etc. within the geo-fence 82, and key parameters of the managed board fleet, including the charge level of the battery units 36, etc.

[0129] By selecting the "Bookings" menu item on the home page (Figure 6a), the bookings for a predefined period can be listed, including, for example, the date, rental duration, rental period, booked mode (Padelec, Cruise, Advanced), payment information, and the aforementioned rating of user 12. Using appropriate filters, the period to be viewed, the user mode, or similar, can be selected to create a list as shown in Figure 6b, from which further business-related information can be derived.

[0130] Under the "Tracking" menu item on the home page (Figure 6a), the "Life Tracking" information shown in Figure 6c, which was already explained above in the discussion of the B2B app, can be accessed. By clicking on the "Financials" menu item on the home page, information required or useful for business analysis can be retrieved at predetermined intervals. An example of such an analysis, performed automatically via the app, is shown in Figure 6d.

[0131] Using the "Rental Prices" submenu on the home page, authorized personnel from Fleet Base 6 or Head Office 1 can set rental prices depending on the season, the day of the week, the time of day, the selected board type (Padelec, Cruise, Advanced) and demand, preferably in consultation with Head Office 1.

[0132] By selecting the "Fleet Management" submenu on the home page (see Figure 6e), an overview of the board fleet offered by the respective fleet base 6 and the spare parts in stock, particularly battery units 36, can be accessed, similar to the B2B app. This submenu can also be used to directly reorder spare parts; this will be discussed later.

[0133] The "Partner Support" submenu (see Figure 6f) on the homepage allows for easy answers to FAQs frequently asked by Fleet Base 6 to Headquarters 1. This submenu also provides access to videos providing detailed instructions, for example, on charging the battery units 36, using the B2B app (mobile app), assembling Board 2, etc., so that most questions can be answered without directly contacting Headquarters 1.

[0134] The B2B desktop app also provides access to an online shop, through which, for example, spare parts (such as the display 38 integrated into the board 2, the battery unit 36, the entire drive unit 26, or the like) can be ordered from headquarters 1. The "Merchandise" submenu allows for the ordering of promotional items and / or promotional packages that can be distributed to potential customers or ordered to intensify advertising.

[0135] The “Settings” submenu can then be used to set details about the team of the respective Fleet Base 6 and the respective authorizations of the team members, for example, regulating access to the “Cockpit” shown in Figure 6a or to the B2B mobile app.

[0136] As explained above, the boards 2 are equipped with extensive sensor technology, which is connected to the control center 1 via the communication modules 58 and the communication network 10, so that the control center 1 is informed online about the maintenance status of the boards 2. The control center 1 is thus able to promptly send maintenance instructions to the fleet base 6 upon detection of possible damage to the board 2, or to perform remote maintenance and, if necessary, also arrange for the replacement of the board 2 or components.

[0137] The "My Profile" menu item allows you to enter the profile of the employee using the B2B desktop app. Logging in and out is done in the usual way.

[0138] Figure 7 shows a mockup of an addition to the customer (B2C) interface 15. Accordingly, after confirmation from Fleet Base 6 that the board has been correctly returned, User 12 has the option of awarding a tip for the responsible employee or Fleet Base 6 using the screen displayed in Figure 7. For this purpose, a slider 84 can be provided, which can be positioned by User 12 in relation to the specified tip items. After pressing the "Send" button, the selected tip is transferred from User 12 to Fleet Base 6 according to the stored payment method and credited to the tip recipient. Instead of the slider 84, each tip item can also be directly selectable via a "push button," or the tip can be entered individually.
