Description

The invention relates to a method for improved customer communication of an ego vehicle with the driver, in which a rear bicycle carrier connected to the ego vehicle is detected by means of a sensor system, and / or a roof rack connected to the ego vehicle, in particular a roof bicycle carrier, is detected by means of the sensor system, wherein a graphic of the ego vehicle with rear bicycle carrier and / or with roof bicycle carrier is displayed on a vehicle-mounted optical output device.Many vehicles today have a rear view camera. With the rear camera, obstacles can be detected when driving backward. In more modern assistance systems, as provided for automatic or partially automatic driving, for example, the following traffic is also monitored by sensors in order to detect hazardous situations. As a quasi-product, the sensors directed against the direction of travel can also detect whether a rear bicycle carrier is connected to the vehicle.WO 2020 / 173772 A1 discloses a method for operating a driver information system with which a graphical representation of the road lying in front of the vehicle and of other road users travelling in front of the vehicle is possible on an optical output device in the cockpit. At a first point in time, first surroundings data in the surroundings of the vehicle are recorded by a sensor system. On the basis of this first environmental data, at least one further road user is identified. A driver information display is generated from the acquired data and output at the optical output device as a first graphical representation. At a second, later point in time, second environmental data in the environment of the vehicle are acquired, and the further road user is identified again on the basis of this data. A second graphical representation is then generated, which replaces the first graphical representation of the further road user. The second graphical representation has a higher specificity than the first graphical representation of the further vehicle. WO 2022 / 214330 A1 relates to a method for operating a driver assistance system, in which a sensor system detects the traffic situation in front of the vehicle and reproduces the detected traffic situation on an optical output system, which is located in the field of view of the driver. In particular, a specific feature of a vehicle driving ahead can be recognized with the method and displayed to the driver. The feature can be, for example, a vehicle roof rack, a roof rack box, a wheel carrier, truck superstructures, in particular a forklift, a trailer of the detected vehicle, an object arranged detachably on the detected vehicle and the like.That is, there are numerous driver assistance systems in the prior art that can capture, process and display the environment of an ego vehicle as an image or graphic on an optical output device in the cockpit of the ego vehicle. Preceding vehicles and their features can be identified in this case in order to sensitize the driver of the ego vehicle to possibly imminent danger situations by the preceding vehicle. It could be advantageous for the driver of the ego vehicle if comparable information for the ego vehicle is displayed to him in the ego vehicle.It is an object of the invention to provide the driver of an ego vehicle with more information about additional equipment of the ego vehicle than is possible by currently known assistance systems.This object is achieved by the method having the features of claim 1. Claims dependent on claim 1 advantageously further develop the method.One aspect of the invention relates to a method for improved customer communication of an ego vehicle with the driver, in which a rear bicycle carrier connected to the ego vehicle is detected by means of a sensor system, and / or a roof bicycle carrier connected to the ego vehicle is detected by means of the sensor system, wherein a graphic of the ego vehicle with rear bicycle carrier and / or with roof bicycle carrier is displayed on a vehicle-mounted optical output device.The roof rack can be, in particular, a roof bicycle rack. A bicycle can be secured in the roof bicycle carrier preferably in a standing position. Standing means here that the bicycle stands on its pneus in corresponding receptacles of the roof bicycle carrier, or that the bicycle is connected to the roof bicycle carrier with the handlebar and the saddle and the wheels of the bicycle project substantially vertically upward. One or more wheels may also be dismounted from the bicycle and transported separately from the bicycle frame. Finally, the bicycle frame without wheels may be connected to the front fork or the front tire and the rear fork or the rear tire may be connected to the roof bicycle carrier. In this case too, the removed wheel or wheels of the bicycle are transported separately.The sensor system may include a plurality of vision sensors which monitor the immediate surroundings of the vehicle in front of, behind and next to the ego vehicle, in order to measure radar sensors which detect a distance of the ego vehicle from an object in front of, behind and next to the ego vehicle, and further sensors which, for example, receive GPS data, measure temperatures and moisture and can receive signals from traffic communication devices or other communication devices. The vision sensors can be, for example, image cameras, infrared cameras or other sensors for detecting at least contours of objects.A graphic is not a realistic image recorded by a camera, for example. Rather, the graphic can be created with a graphic program. In this case, the graphics program can rely on stored data of individual graphics elements and assemble these to form an overall graphics in accordance with the data reported by the sensors. The graphic elements can be geometric basic shapes, a graphic of the ego vehicle in any view, a graphic of a rear bicycle carrier or graphics of different rear bicycle carriers and a roof bicycle carrier or different roof bicycle carriers, a graphic generally standing for any bicycle and / or graphics each representing a type or model of a bicycle. For example, an e-bike, a racewheel, a childwheel, a cargowheel, a mountain bike and a recreational wheel can be considered as a bicycle model, which enumeration is not exhaustive.In one embodiment, a total number of bicycles secured in the rear bicycle carrier and / or in the roof bicycle carrier can be detected by the sensor system and the total number of bicycles can be displayed in the graphic of the ego vehicle with rear bicycle carrier and / or roof bicycle carrier. This can mean, for example, that the number of bicycles is displayed as a number or by corresponding bicycle symbols above, below or next to the graphic of the ego vehicle with the rear bicycle carrier and / or the roof bicycle carrier. If only a single bicycle carrier is connected to the ego vehicle, all displayed bicycles are arranged in this bicycle carrier.In one embodiment, the sensor system can detect the number of bicycles secured in the rear bicycle carrier and / or the bicycles secured in the roof bicycle carrier. The sensor system can associate the detected bicycles with the rear bicycle carrier and / or the roof bicycle carrier and display the bicycles in the graphic representation of the ego vehicle with a bicycle carrier or the two bicycle carriers in the corresponding bicycle carrier.If the sensor system is configured to recognize the model of each individual bicycle, each model can be represented by its own graphic or symbol. As already stated, the models can be assigned to the respective bicycle carrier and, in one embodiment, to a one-to-one position within the bicycle carrier. That is, in a bicycle carrier having receptacles for four bicycles, the bicycles can be displayed in the graph as being arranged side by side in the bicycle carrier. This also applies if only a single bicycle is arranged in the bicycle carrier.In the graph showing the ego vehicle with the bicycles, the maximum height of the vehicle-bicycle carrier assembly, its maximum width and the maximum length can be indicated in a well-visible manner to the rider. In addition, in the case of a rear bicycle carrier, a minimum perpendicular distance to the road surface can be specified. As further details, a maximum permissible wind speed transversely to the direction of travel and / or a representation of the current wind direction and the current wind speed can be displayed in the graph.In one embodiment, it can be indicated to the driver, for example, by changing the color of the graphic and / or flashing the graphic, that the current situation, such as entering a low garage, passing through a bridge with critical passage height or a crosswind above a predefined limit value, requires full attention. At the same time, a warning sound can be sounded. If the ego vehicle is set up to drive autonomously or automatically at a level >3, a driver assistance system can monitor whether the driver responds to the visual and / or acoustic warning.In one embodiment, the bicycle or each of the bicycles may include a communication device. Such a communication device may be advantageous for traffic safety by sending signals which may be received from other vehicles, such as cars, light trucks, motor cycles or trucks and converted into warning signals which alert the rider of the bicycle moving in the environment in the vehicle. The communication device can, for example, receive positioning signals (for example GPS signals) and transmit its current position continuously, in a clocked manner or in the event of a request to a receiver. The ego vehicle can receive the signals of the communication device of the bicycle via a further sensor. In one embodiment, the signal may include information about the bicycle model. The further sensor of the ego vehicle can preferably simultaneously record and distinguish a plurality of signals from bicycles. This means that the sensor can record the number of transmitting communication devices on the basis of the signals and / or assign a model of the respective bicycle to each of the transmitting communication devices and their exact arrangement in the bicycle carrier and preferably to each of the transmitting communication devices.In order to ensure that the received signal or signals do not come from bicycles that move in the vicinity of the ego vehicle and also comprise a communication device, it can be confirmed, upon the receipt of a communication signal of a bicycle by the sensor system, i.e. in particular by the vision sensors, that no bicycle is detected in front of, behind or next to the ego vehicle. Another indication that the received communication signal comes from a bicycle connected to the ego vehicle may be that the ego vehicle is moving at a speed that is greater than a predetermined threshold value, and the received communication signal does not attenuate or disappear. The limit value can be ≥70 km / h, for example, while in steep ramps and ramps, for example in a mountain region, another limit value can apply. A further indication that the received communication signal comes from a bicycle connected to the vehicle may be that geodata such as GPS data of the ego vehicle and GPS data of the bicycle are substantially identical despite, for example, changes in roadway or direction over a preferably predefined longer time.The graphic displayed on the optical output device can be created by a technical system of the ego vehicle. The technical system may include a control unit and a computer. A graphics program can run on the computer, which calculates the graphics.In one embodiment, the control unit can comprise a memory which is connected to the computer and in which graphics elements for the ego vehicle, the bicycle carrier, the bicycle and / or bicycle models are stored, which graphics elements can be used or assembled by the graphics program of the computer for generating the graphics.In one embodiment, in addition to the display of the ego vehicle with the bicycle carrier / carriers and the bicycle / bicycles, the graphic can be displayed to the rider of the ego vehicle a maximum height of the ego vehicle-roof carrier assembly and / or a minimum distance of the rear bicycle carrier to a travel surface on which the ego vehicle is standing or travelling. Furthermore, the current wind direction and the current wind intensity can be displayed in the graph.A second aspect relates to a technical system for creating and displaying a graphic for the method according to the first aspect. The technical system comprises at least one control unit, a sensor system, the sensors of which are connected to the control unit, a memory in which graphics elements are stored, and a computer on which a graphics program runs. The computer can calculate a graphic from the information of the sensor system sent to the control unit and the graphic elements stored in the memory and send it to the optical output device via the control unit for display.By the graphical representation of the ego vehicle with the bicycle carrier, the rider is reminded, especially during longer journeys, that a bicycle carrier is connected to the ego vehicle. The optional acoustic and / or visual warnings of obstacles and / or critical weather conditions promptly increase the attention level of the driver in the area of critical situations in advance. The optional details about the maximum dimensions of the combination of the ego vehicle, the bicycle carrier and the bicycle arranged in the bicycle carrier or the ground clearance in the region of the rear bicycle carrier and / or the current wind direction and wind intensity enable it to make decisions in good time that prevent damage to the bicycle, the bicycle carrier and the ego vehicle.All technical features described with respect to the method according to the first aspect also apply to the technical system according to the second aspect, and vice versa.The invention is explained in more detail below with reference to figures. The figures show in detail: FIG. 1 : a method as a flow chart; FIG. 2 : shows a technical system of an ego vehicle for carrying out the method of FIG. 1 ; FIG. 3 : Examples of graphic representations of the ego vehicle with bicycle carrier on an optical output device in the cockpit of the ego vehicle.FIG. 1 shows a flow chart of a method with which the interaction between an ego vehicle 10 and the rider is improved by displaying a graphic of the ego vehicle 10 with a bicycle carrier 40, 50 on an output device 60 in the cockpit of the ego vehicle 10. Essential aspects of the method are described below with reference to five method steps I, II, III, IV, V. The process steps I, II, III, IV, V can be carried out in the described sequence, but the sequence can also be changed. The reference numerals for technical features used to describe the method are all taken from FIG. 2.When carrying out the method, in a first method step I, a bicycle carrier 40, 50 connected to the ego vehicle 10 is detected by means of a sensor system of a technical system of the ego vehicle 10, or the assembly of a bicycle carrier 40, 50 is confirmed by the rider manually in, for example, a sub-menu of an assistance system of the ego vehicle 10. The bicycle carrier 40, 50 may be a rear bicycle carrier 40 connected to a rear of the ego vehicle 10, or a roof bicycle carrier 50 mounted on a roof of the ego vehicle 10.According to the current state of the art, the rear bicycle carrier 40 can be directly or directly detected by the sensor system. The rear bicycle carrier 40 can be detected, for example, by a vision sensor S 2 of the sensor system of the ego vehicle 10, which detects objects behind the ego vehicle 10. The detected rear bicycle carrier 40 can be graphically edited by a computer of the technical system on which a graphics program runs. Subsequently, the graphic showing the ego vehicle 10 with the rear bicycle carrier 40 is output at the optical output device 60.In the first method step I, the sensor system can furthermore determine that a roof bicycle carrier 50 is connected to the ego vehicle 10. Since known vehicles currently do not comprise a vision sensor which transmits an image of the vehicle roof into the cockpit, the detection of the roof bicycle carrier 50 by the sensor system can take place only indirectly or indirectly.In order to enable this indirect detection of the roof bicycle carrier 50, a bicycle 20 can be arranged in the roof bicycle carrier 50, for example, which comprises a communication device 70 that emits signals that can be detected by a sensor S 5 of the sensor system of the ego vehicle 10. The communication device 70 may be active only when the bicycle 20 is moved, in one embodiment. If the sensor system receives a signal of the communication device 70 during the preparation for a trip, a graphic of the ego vehicle 10 with the roof undercarriage 50 can be calculated by the technical system. This graphic can be displayed on the optical output device 60.In one embodiment, a graphic can be calculated and displayed on the optical output device 60 that shows the ego vehicle 10 having a rear bicycle carrier 40 and a roof bicycle carrier 50.When driving off with the ego vehicle 10, the roof bicycle carrier 50 can be confirmed, for example, by the sensor system receiving the signal of the communication device 70 from the bicycle 20, but the ego vehicle 10 simultaneously driving at a speed that is above a predefined limit value. Even if the signal of the communication device 70 is received and at the same time the sensor system does not detect a bicycle 20 in front of, next to or behind the ego vehicle 10, the roof bicycle carrier 50 can be indirectly confirmed. The same applies if the geodata of the ego vehicle 10 and of the bicycle 20 remain substantially identical to changes in lanes or directions of the ego vehicle 10 over a longer period of time.In a second method step II, the sensor system can determine a total number of bicycles 20 connected to the ego vehicle 10 in the bicycle carrier or carriers 40, 50 and output in the graphic. It is assumed here that each of the bicycles 20 or at least each of the bicycles 20 arranged in the roof bicycle carrier 50 comprises a communication device 70. Here, the number of bicycles 20 may be indicated as a number next to the graph, or the number of bicycles is indicated by symbols.In a third method step III, the bicycles 20 can be assigned to the respective bicycle carrier 40, 50 and shown arranged in the corresponding bicycle carrier 40, 50 in the graphic representation. Instead, the recordings for the bicycles 20 can be represented in the graph of the bicycle holders 40, 50, and if, for example, two bicycles 20 are recorded in a rear bicycle holder 40 with three recordings, two of the recordings color, e.g. red, while one of the recordings remains green-colored. The same applies to the roof bicycle carrier 50.In a fourth method step IV, the model can be determined for each of the bicycles 20 arranged in the bicycle carriers 40, 50 and can be represented in the graph as a symbol, for example in the manner of an emoji.In a fifth method step V, the graphic can be supplemented by further information. The further information can be, for example, a maximum height of the ego vehicle-roof bicycle group, a minimum ground clearance of the rear bicycle carrier 40 with respect to the roadway and / or information about a current wind direction and wind intensity or a maximum expected wind intensity at the travel time in the region of bridge crossings and / or a tree-free nature.Finally, the technical system can generate a visual and / or acoustic warning for the driver of the ego vehicle 10 if the ego vehicle 10 is approaching an obstacle with a limited passage height, the ego vehicle 10 is steered into a low-ground garage or the weather forecast predicts gusts of wind with a strength which can lead to a sudden transverse offset and / or rocking of the ego vehicle 10 at least during a bridge trip on account of the greater area of attack transversely with respect to the direction of travel.FIG. 2 shows schematically a technical system 100 of an ego vehicle 10. the technical system 100 comprises a control unit 80, a sensor system having sensors S 1, S 2, S 3, S 4, S 5, S 6, S 7, a computer 85, a memory 90 and an optical output device 60.The sensors S 1, S 2, S 3, S 4 are vision sensors and / or radar sensors which monitor an environment surrounding the ego vehicle 10. The sensors S 1, S 2, S 3, S 4 can at least detect, identify objects in front of, next to and behind the ego vehicle 10 (immobile object, vehicle, type vehicle, two-wheeler, type two-wheeler) or measure distances to the objects. The acquired data is sent from the sensors S 1, S 2, S 3, S 4 to the control unit 80.The sensor S 5 is a first sensor that can receive signals from a communication device 70 comprised by a bicycle 20. The sensor S 6 may be a second sensor for receiving geodata, the sensor S 7 may be a third sensor and may acquire current weather data, for example. The sensors S 5, S 6, S 7 are also connected to the control unit 80.In the exemplary embodiment shown, the computer 85 is part of the control unit 80 and can use the control unit 80 to access the data recorded by the sensors S 1, S 2, S 3, S 4, S 5, S 6, S 7. A graphics program runs on the computer 85, which graphics program calculates a graphic of the ego vehicle 10 with a bicycle carrier 40, 50 and a bicycle 20 from the data. This graphic can then be displayed on an optical output device 60 in the cockpit of the ego vehicle in the field of vision of the driver.The computer 85 is connected to a memory 90. The storage 90 may be a vehicle-mounted storage element or a cloud to which the ego vehicle 10 has access. The memory 90 can store graphics elements which the computer 85 can use to generate the graphics.FIG. 3 shows two examples of graphics G 1, G 2 as calculated by computer 85 and output at optical output device 60.The graph G 1 shows a perspective view of the ego vehicle 10 having a rear bicycle carrier 40 and a bicycle 20 standing in the rear bicycle carrier 40. As can be easily seen from the graph G 1, an overall length of the combination ego vehicle 10 plus bicycle 20 changes due to the mounted rear bicycle carrier. The entrance into the deep garage can be steep and at the end can transition abruptly into the plane of the deep garage floor. In particular, if the speed of the ego vehicle 10 is too high in this situation, the rear bicycle carrier 40 may thereby be mounted and damaged. This effect can be enhanced by the tendency of the ego vehicle 10 to spring at the transition from the steep descent to the flat ground and / or a sudden deceleration of the ego vehicle 10 at this moment.In addition, the riding of the bicycle 20 in the rear bicycle carrier 40 changes the drag coefficient of the ego vehicle 10, resulting in a shorter range due to higher power consumption in the battery-powered engine or higher fuel consumption in a combustor. The maximum range of the group may change depending on the energy supply of the ego vehicle 10 and a profile of the planned route. This may be displayed to the driver of the ego vehicle 10 in the graph G 1.Graph G 2 shows the ego vehicle 10 having a roof track 50 and a front-wheelless bicycle 20 standing in the roof track 50. An overall height of the ego vehicle 10 plus the roof bicycle carrier 50 plus the bicycle 20 combination may be additionally displayed to the rider of the ego vehicle 10 in the graph G 2. The navigation system can use the ascertained total height to check the route for possible hazard zones with ride height restriction and inform the driver of the ego vehicle 10 in good time that he is approaching a hazard zone.In this combination as well, the air resistance value of the ego vehicle 10 changes markedly, and at the same time an area for attack by a wind moving transversely to the direction of travel increases. The larger engagement surface may result in the ego vehicle 10 suddenly undergoing a lateral offset, for example, when crossing a bridge. The additional engagement surface formed by the bicycle also has a leverage effect on the ego vehicle 10, so that the ego vehicle 10 can be set in a rocking motion transversely to the direction of travel in the case of strong gusts and in the extreme case can tip over. It can therefore be advantageous if a wind direction and a maximum wind speed are also displayed in the graphic G 2, if a corresponding poor weather warning is disclosed, for example, via the traffic radio.List of reference charactersI method step II method step III method step IV method step V method step 10 ego vehicle 20 bicycle 40 rear bicycle carrier 50 roof bicycle carrier 60 optical output device 70 communication device 80 control unit 85 computer 90 memory 100 technical system G 1 graphic G 2 graphic S 1 sensor S 2 sensor S 3 sensor S 4 sensor S 5 sensor S 6 sensor S 7 sensorReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
