Description

Field of the Invention

[0001] The present invention relates to a method for operating an unmanned aerial vehicle for a motor vehicle charging station, a corresponding unmanned aerial vehicle, and a motor vehicle charging station. Background Art

[0002] From the prior art, for example, the document US2022 / 0089147 A1 is known. This document describes an information processing device having a control device, which is configured to perform the following: obtain information in order to associate the parking space where the user parks with the user; obtain information about signs of the user's return to the parking space; and notify another waiting user to wait for parking at the location of the parking space when obtaining information about signs of the user's return to the parking space. Summary of the Invention

[0003] The object of the present invention is to provide a method for operating an unmanned aerial vehicle for a motor vehicle charging station, which has advantages compared with known methods, in particular to provide particularly targeted assistance for the user of the motor vehicle, preferably for the charging process of the energy accumulator of the motor vehicle at the motor vehicle charging station.

[0004] According to the present invention, this is achieved by a method for operating an unmanned aerial vehicle for a motor vehicle charging station having the features of claim 1. It is hereby stipulated that the aircraft projects an image intended to assist the motor vehicle user onto a projection surface by means of a projector at least temporarily.

[0005] Advantageous designs of the present invention with suitable improvements are given in the dependent claims. It should be noted that the embodiments explained in the description are not restrictive; on the contrary, any variations of the features disclosed in the description, claims, and drawings can be implemented.

[0006] This method is for operating an unmanned aerial vehicle. An unmanned aerial vehicle is usually also referred to as a "drone", and preferably is an aircraft in such a form that it moves automatically or at least partially automatically, especially is designed to automatically or partially maintain its position within a specific time period. The aircraft is especially a heavier-than-air aircraft having a power drive. In this regard, the aircraft exists in the form of a helicopter or a multi-rotor aircraft, for example. In terms of its classification according to the EASA technical level, the aircraft belongs to class C2 at most, preferably belongs to class C1 at most. For example, a multi-rotor aircraft is a three-axis aircraft, a four-axis aircraft, a six-axis aircraft, or an eight-axis aircraft, for example.

[0007] Preferably, the aircraft is designed to have an electric drive, in particular one or more electric motors. In particular, the electric motor is an electronically commutated brushless DC motor (BLDC). The electric drive is supplied with electrical energy by an electrical energy storage device, where the energy storage device is mounted on the aircraft. Additionally, the aircraft preferably has one or more of the following devices: a satellite signal navigation device, an inertial navigation device, an altitude measurement device, a compass.

[0008] Preferably, the aircraft is part of a motor vehicle charging station, but can of course also exist and / or operate independently of the motor vehicle charging station. The motor vehicle charging station is set up and designed to charge the energy storage device of a motor vehicle. In this context, the motor vehicle is at least partially electrically powered, in particular a fully electric vehicle. In order to charge the motor vehicle, more precisely its energy storage device, the motor vehicle charging station has at least one charging point, i.e., exactly one charging point or multiple charging points. At each charging point, there are devices that can be used to charge the motor vehicle.

[0009] In this context, at each charging point of the motor vehicle charging station, the motor vehicle charging station charges the motor vehicle or provides electrical energy to the motor vehicle. If at least one charging point or the charging point is mentioned within the scope of the description, these embodiments are always equivalent and can be converted into each other. These embodiments can also preferably be transferred to each of the multiple charging points (if any) of the motor vehicle charging station.

[0010] Preferably, the motor vehicle charging station, more precisely its charging points, is set up and designed for rapid charging of motor vehicles. Since the motor vehicle charging station is not necessarily connected to a power grid that can always supply sufficient power to multiple charging points, the motor vehicle charging station preferably has an electrical buffer. The electrical buffer has a capacitance of, for example, at least 0.5 MWh, at least 0.7 MWh, or at least 0.9 MWh. Particularly preferably, an energy storage device is assigned to each charging point, such that in the case of multiple charging points, each of the charging points has one such energy storage device. However, it can also be provided that multiple charging points are electrically connected to a common buffer. In any case, there is thus sufficient charging power for the motor vehicle.

[0011] The electrical connection between the motor vehicle and the charging point for charging is realized in a wired or wireless manner. In the wired case, a continuously conductive electrical connection between the motor vehicle and the charging point is preferably established. In the wireless case, the connection is at least partially inductive. For example, the conductive connection is realized via a charging cable, which is electrically connected to the motor vehicle by means of a plug-in connection. Preferably, the charging cable is arranged at a displaceable charging arm, which guides the charging cable in a swingable manner. Particularly preferably, the charging arm has an electric drive, which displaces the charging cable in the direction of the charging interface of the motor vehicle and / or in a direction preset by the user. Thereby, the establishment of the electrical connection between the motor vehicle and the motor vehicle charging station is significantly simplified.

[0012] Since the structure of the motor vehicle is now relatively complex or its operation may be relatively complex, the motor vehicle charging station is designed to have auxiliary facilities. The auxiliary facilities include an aircraft, which is operated at least temporarily to assist the user of the motor vehicle. The aircraft has a projector, by means of which an image intended to assist the user is projected onto a projection surface at least temporarily. This means that an image is generated, for example, generated by the aircraft and / or generated in a control center connected to the aircraft via a communication connection, and then the image is output by means of the projector.

[0013] In principle, a projector is understood to be any optical device that can be used to output an image. For example, the projector exists in the form of a video projector or a laser projector. In any case, the projector is set and designed to project different images. In this regard, the image is not static but variable. For example, the projector has a light source and an image converter, such as an integrated circuit, especially a liquid crystal display (LCD) or a digital micromirror device (DMD).

[0014] The projection surface onto which the projector projects the image can in principle also be selected arbitrarily. However, the arrangement, size and orientation of the projection surface are such that the user can see the image without any problem, and thus the user is effectively assisted by the aircraft. In principle, it is feasible to project the image by means of a static projector arranged, for example, on the roof of the motor vehicle charging station. However, due to the use of the motor vehicle charging station by multiple different motor vehicles, this does not have sufficient flexibility.

[0015] Merely using the aircraft for positioning the projector satisfactorily ensures free positioning, thus ensuring adaptation to different motor vehicles. This is particularly important when the projection surface is partially or completely located on the motor vehicle. Only in this way can it be reliably ensured that, in the case of multiple different motor vehicles (which can additionally have different positions relative to the motor vehicle charging station), user assistance can be carried out targeted by means of the projector.

[0016] An improved embodiment of the present invention provides that a motor vehicle charging station has a hangar for an aircraft, and when an assistance request occurs, the aircraft is controlled to fly from the hangar towards the direction of the motor vehicle and / or the user. Therefore, the aircraft remains in the hangar until an assistance request occurs. Preferably, electrical energy is supplied to the aircraft here to charge the accumulator of the aircraft. When an assistance request occurs, the aircraft is put into operation and controlled to fly from the hangar towards the motor vehicle or its user. Preferably, the hangar can be closed, i.e., for example, it has a hangar door, and preferably, the hangar door is designed as a rolling shutter door or a folding door / tilting door. The hangar door is usually closed, especially so that the aircraft cannot be accessed from the external environment of the hangar. For example, the hangar door is only opened to allow the aircraft to leave the hangar when an assistance request occurs.

[0017] It can be provided that the motor vehicle charging station has a plurality of aircraft, and these aircraft are all designed to be similar to the described aircraft. These multiple aircraft can be arranged in a shared hangar or multiple hangars at least temporarily. For example, a hangar with an aircraft is assigned to each charging point. It can be provided that when a motor vehicle is arranged at one of the charging points and an assistance request occurs, the aircraft assigned to this charging point is controlled to fly towards the direction of the motor vehicle or the user. However, it can also be provided that, for example, if the state of charge of the battery of the aircraft is too low, one of the other aircraft is used. Therefore, reliable user assistance is achieved in any case.

[0018] An improved embodiment of the present invention provides that the assistance request is triggered by the user or is triggered after a specific period of inactivity. In this regard, the assistance request can be triggered in different ways. On the one hand, the assistance request can be triggered by the user himself, for example, via an operating element of the motor vehicle charging station and / or by means of a mobile device (such as a mobile phone, a tablet computer, etc.). Additionally or alternatively, if it is determined that there is no activity for a specific period of time, the assistance request is triggered. For example, inactivity is understood as the motor vehicle being parked at the charging point without performing other operations, especially charging the motor vehicle. In this case, it is assumed that the user needs charging assistance and triggers the assistance request. This reliably ensures that the user fully obtains assistance.

[0019] An improved embodiment of the present invention provides that one of the following is used as a projection surface: the wall surface of the motor vehicle charging station, the ground surface of the surrounding environment of the motor vehicle, the body surface of the motor vehicle, and the inner space surface of the motor vehicle. An image is projected onto this projection surface by means of a projector of the aircraft. The projection surface completely or at least partially exists on one of the said surfaces. For example, the wall surface of the motor vehicle charging station can be used, and in particular, this wall surface is a vertical wall surface. For example, this wall surface is designed to be reflective, especially by means of a reflective coating.

[0020] The ground for parking a motor vehicle can also be used as a projection surface. For example, the following ground portion is used as a projection surface, and this ground portion is designed to be reflective, for example, by applying a reflective coating to the ground. In addition, the body surface of the motor vehicle itself can be used as a projection surface. For example, this body surface exists at the engine hood, the trunk lid, or the doors of the motor vehicle. It can be provided that the motor vehicle automatically displaces one of the elements by means of an actuator to provide a projection surface.

[0021] As an addition or alternative to the body surface, an interior space surface is used as a projection surface. The interior space surface is understood to be a surface in the interior space of the motor vehicle, such as a surface in the passenger compartment of the motor vehicle, the luggage compartment of the motor vehicle, or the engine compartment of the motor vehicle. In this regard, for example, the inner side of the engine hood can have this interior space surface. The surface of the instrument panel can also be used as an interior space surface. Thereby, for example, by preferably gradually displaying technical instructions / guiding on the projection surface, targeted assistance can be provided when a technical problem occurs.

[0022] Particularly preferably, when projecting an image onto the projection surface, the geometry of the projection surface is taken into account. This is especially important if the projection surface is on the motor vehicle because the outer surface of the motor vehicle is usually not flat. It can be provided that the geometry of the projection surface used accordingly is stored for different motor vehicles, and after the motor vehicle is recognized at the aircraft or motor vehicle charging station, the stored geometry is used when projecting the image. Alternatively, the geometry of the projection surface can be determined by the projector or the aircraft itself, especially by means of a suitable device, such as a laser scanner. Thereby, regardless of the selection of the projection surface, the user can always perfectly see the image.

[0023] An improvement of the present invention provides that the motor vehicle is connected to the motor vehicle charging station and / or the aircraft via a data connection, and a projection surface is provided by displacing motor vehicle components as required. For example, the motor vehicle components are the engine hood, the trunk lid, the doors, the fuel filler cap, or the fuel filler cover, etc. Here, the fuel filler cap is also understood to be a cover for an electrical charging interface. In particular, if the aircraft requires a specific projection surface but cannot provide this projection surface currently, the motor vehicle is informed of this situation via the data connection. Subsequently, the motor vehicle displaces the motor vehicle components to provide this projection surface. For example, in this way, the inner side of the engine hood can be used as a projection surface to assist the user in a targeted manner and at the part where the operation should be performed.

[0024] An improvement of the present invention provides that the aircraft projects an image to achieve one of the following functions: guiding the motor vehicle to a charging point, giving the user an operation instruction for the use operation of the motor vehicle, and giving the user an operation instruction for charging the accumulator of the motor vehicle by means of the motor vehicle charging station. Therefore, first, the aircraft can be used to navigate the motor vehicle or its user to the charging point.

[0025] This handling method is particularly important if the motor vehicle charging station has multiple charging points. In this case, when a motor vehicle arrives, the motor vehicle charging station selects one of the charging points, and the flying vehicle projects an image so that the user of the motor vehicle can drive the motor vehicle to the selected charging point. At this time, the image especially includes navigation instructions in the form of, for example, guiding signs projected onto the projection surface. In particular, as the projection surface, the body surface of the motor vehicle (such as the engine hood of the motor vehicle) or the ground of the surrounding environment of the motor vehicle is used.

[0026] In addition, an image can be projected to give operation instructions to the user. The operation instructions are used to implement usage operations, such as opening the fuel filler cap, the engine hood, etc. For example, the flying vehicle demonstrates the necessary operation steps for achieving a specific purpose or implementing a usage operation by means of the projected image. In particular, for this purpose, the flying vehicle detects the work steps completed by the user and adapts the image to the work steps. Additionally or alternatively, the projected image is used to introduce operation instructions for charging the energy storage device to the user. For example, the instructions are given step by step again to electrically connect the motor vehicle to the charging point or at the motor vehicle charging station to charge the energy storage device. Thereby, a particularly high level of operating comfort of the motor vehicle charging station is achieved.

[0027] Other application scopes of the flying vehicle are also conceivable and are used at least temporarily additionally or alternatively. That is, for example, it can be stipulated that test vehicles for test drives are provided at the motor vehicle charging station. Therefore, the user of the motor vehicle can use the time when their motor vehicle is being charged to test drive the test vehicle. On the one hand, it can be stipulated that the flying vehicle again guides the user to the test vehicle by projecting an image, and if there are multiple test vehicles provided, the test vehicle to be used is highlighted by means of a marker. Additionally or alternatively, the flying vehicle is used to record images for the user during the test drive, especially video recording. For this purpose, the flying vehicle moves together with the test vehicle in a defined relative position to the vehicle and records video for the user in the test vehicle.

[0028] An improved solution of the present invention stipulates that the flying vehicle has at least one of the following devices: a screen, by means of which at least temporarily additional images are displayed; a speaker, by means of which at least temporarily a sound output signal is output; a microphone, by means of which at least temporarily a sound input signal is recorded; and a camera, by means of which at least temporarily photos are taken. Therefore, in addition to the projector, the flying vehicle additionally has, for example, a screen. By means of this screen, at least temporarily additional images are output. For example, the said image is displayed by means of the projector and additional images are displayed by means of the screen at the same time. It can be stipulated that an artificial assistant or an avatar image of the assistant is displayed by means of the screen, while the projector is used to reproduce the operation instructions. Thereby, an emotional connection is established with the user.

[0029] Additional or alternatively provided speakers are used to output an audio output signal at the location of the vehicle. For example, the audio output signal includes voice operation instructions for the user, or communication with an assistant is achieved by means of the speakers. Preferably, a microphone is also used for this purpose, and an audio input signal is recorded by means of the microphone. For example, both the microphone and the speakers are used for communication with the assistant, thereby establishing a voice connection between the assistant and the user of the vehicle.

[0030] In addition, the vehicle may have a camera. Photos are taken at least temporarily by means of the camera, for example, photos of the vehicle. For example, this is used to identify the vehicle and to provide assistance to the user based on the vehicle. Other application areas of the camera have been pointed out. In addition, the camera can be used to photograph areas of the vehicle that are difficult to reach. Subsequently, these photos are displayed to the user of the vehicle by means of the said image or another image or under the condition of using other display devices. Thereby, the user can conduct a comprehensive inspection of their vehicle without physical exertion and without the risk of soiling their clothing.

[0031] An improvement of the present invention provides that the vehicle communicates with a control center via a communication connection, and the control center provides the said image and / or the said other image and / or the audio output signal, and / or evaluates the audio input signal and / or the photos. In this regard, the vehicle is, for example, partially automated. In particular, the control center presets a theoretical position for the vehicle and controls the vehicle to drive independently towards the theoretical position. However, the interaction between the vehicle and the user is preset or taken over by the control center. For this purpose, the said signals are provided and evaluated. Thereby, particularly targeted user assistance is obtained.

[0032] An improvement of the present invention provides that the vehicle and / or the user are at least temporarily video-recorded by means of another camera arranged in a vehicle charging station. For example, this other camera is used to identify the vehicle, more precisely the type of the vehicle. This other camera can also be used to accurately determine the position of the vehicle, especially the relative position of the vehicle to the vehicle and / or the user. Therefore, particularly reliable vehicle navigation is achieved.

[0033] In addition, the present invention relates to an unmanned aerial vehicle for a vehicle charging station, especially for performing a method according to an embodiment within the scope of this specification, wherein the vehicle charging station has at least one charging point for the vehicle. Here, the vehicle is arranged and designed to project an image intended to assist the user of the vehicle onto a projection surface at least temporarily by means of a projector.

[0034] The design of such aircraft or the advantages of such processing methods have been pointed out. Not only the aircraft but also the method for operating the aircraft can be improved according to the embodiments within the scope of this specification, and thus reference is made to these embodiments in this regard.

[0035] Of course, the present invention also relates to a method for operating a motor vehicle charging station, which has at least one charging point for a motor vehicle and an unmanned aerial vehicle, in particular according to the embodiments in this specification. Here, it is stipulated that the aircraft projects, at least temporarily, an image intended to assist the motor vehicle user onto a projection surface by means of a projector.

[0036] Finally, the present invention relates to a motor vehicle charging station, which has at least one charging point for a motor vehicle and an unmanned aerial vehicle, in particular an unmanned aerial vehicle according to the embodiments in this specification and / or for carrying out the method already explained. For this purpose, the aircraft is set up and designed to project, at least temporarily, an image intended to assist the motor vehicle user onto a projection surface by means of a projector.

[0037] The features and combinations of features described in the specification, in particular those described in the following description of the drawings and / or shown in the figures, can be used not only in the correspondingly given combinations, but also in other combinations or individually, without departing from the scope of the present invention. Thus, embodiments that are not explicitly shown or explained in the specification and / or the drawings but can be derived from or deduced from the explained embodiments are also considered to be included in the present invention. Description of the Drawings

[0038] The present invention will be explained in more detail below based on the embodiments shown in the drawings without limiting the present invention. Here, the sole drawing shows:

[0039] Figure 1 A schematic view showing a motor vehicle charging station and a motor vehicle located at the motor vehicle charging station. Detailed Description of the Embodiments

[0040] Figure 1 A schematic view showing a motor vehicle charging station 1 and a motor vehicle 2 arranged at a charging point 3 of the motor vehicle charging station 1. The motor vehicle charging station 1 has, at the charging point 3, a preferably height-adjustable, in particular automatically adjustable, display device 4 and an operating device 5. For example, the display device 4 and the operating device 5 can be adjusted in height independently of each other. The motor vehicle charging station 1 has an unmanned aerial vehicle 6, here, which is in the form of a multi-rotor aircraft, for example a quadcopter.

[0041] The aircraft 6 has a projector 7, which is in particular arranged at the underside of the aircraft 6. Particularly preferably, the projector 7 is arranged pivotably at the aircraft 6, more precisely at the base body of the aircraft 6. For this purpose, the projector is connected to the base body via an actuator. In addition, the motor vehicle charging station 1 has a hangar 8 for the aircraft 6. The hangar 8 is located, for example, above the display device 4 and is particularly preferably closable. For this purpose, the hangar 8 has, for example, a hangar door.

[0042] By means of the projector 7, the aircraft 6 projects an image onto the projection surface 9 at least temporarily. Merely by way of example, two different projection surfaces 9 are shown here, namely the wall surface of the motor vehicle charging station 1 and the body surface of the motor vehicle 2. Here, the body surface - by way of example - is the outer side of the engine hood. However, other surfaces can also be used as the projection surface 9, such as the ground in the surroundings of the motor vehicle and / or the interior space surface of the motor vehicle 2.

[0043] The aircraft 6 provides assistance to the user of the motor vehicle 2 in a targeted manner. For example, the assistance can be aimed at navigating the motor vehicle 2 to the charging point 3 and / or carrying out the charging process of the motor vehicle 2 at the charging station 3. At this time, instructions imaged in the form of an image on the projection surface 9 are given to the user step by step. It is particularly preferably provided that an image of the first working step of the corresponding step sequence is imaged first. Preferably, the execution of the working steps is monitored by the aircraft 6 by means of suitable devices. Only after it is confirmed that the user has carried out the working step is the image corresponding to the second working step projected. Conversely, if it is confirmed that the user has remained in the first working step for a long time, the image is changed to specify the operation instructions and / or contact an artificial assistant.

[0044] Other areas of application of the aircraft 6 are also conceivable. On the one hand, for example, the operations of the user can be recorded by means of a camera of the aircraft 6 in order to be able to provide assistance in a targeted manner. It can also be evaluated how the user specifically carries out a particular operation, such as charging the motor vehicle 2. Similarly, by checking different points on a checklist, operation instructions for the maintenance of the motor vehicle 2 can be given. This means that the projector 7 projects a plurality of images each aimed at specific operation instructions in succession so that the user can check the motor vehicle 2. It is also possible to fly the aircraft 6 to a specific part of the motor vehicle 2 in a targeted manner and take a photograph by means of a camera. Subsequently, the photograph thus obtained is evaluated to detect possible faults at an early stage. Thereby, the maintenance workload of the motor vehicle 2 can be reduced.

[0045] If the aircraft 6 is not used to assist the user of the motor vehicle 2, the aircraft can be used to observe the surrounding environment. For example, the aircraft 6 moves on a preset movement trajectory around the motor vehicle charging station 1 to detect and display unauthorized operations. It can also be stipulated to check the movable charging arm of the motor vehicle charging station 1 for charging the motor vehicle 2. For this purpose, for example, the aircraft 6 is moved to a specific position and the charging arm is video-recorded by means of a camera. Subsequently, the charging arm is controlled to be displaced. If it is confirmed by the camera that the charging arm has not been displaced or has not been displaced sufficiently, a fault of the motor vehicle charging station 1 is reported. Thereby, a very high flexibility of the aircraft 6 is given.
