Description

[0001] The invention relates to a method for improved customer communication between an ego vehicle and 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 luggage carrier 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.

[0002] Many vehicles today are equipped with a rearview camera. This camera can detect obstacles when reversing. More modern assistance systems, such as those designed for automated or semi-automated driving, also use sensors to monitor following traffic to detect dangerous situations. As a byproduct, the sensors facing the rear of the vehicle can also detect whether a rear-mounted bicycle rack is connected to the vehicle.

[0003] WO 2020 / 173772 A1 discloses a method for operating a driver information system which enables a graphical representation of the road ahead of the vehicle and other road users driving in front of the vehicle to be displayed on an optical output device in the cockpit. At a first point in time, a sensor system records first environmental data in the vehicle's surroundings. Based on this first environmental data, at least one other road user is identified. A driver information display is generated from the recorded data and output on the optical output device as a first graphical representation. At a second, later point in time, second environmental data in the vehicle's surroundings are recorded, and based on this data, the other road user is identified again. A second graphical representation is then generated, which replaces the first graphical representation of the other road user.The second graphical representation has a higher degree of specificity than the first graphical representation of the further vehicle. WO 2022 / 214 330 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 displays the detected traffic situation on an optical output system located within the driver's field of vision. In particular, the method can detect a specific feature of a vehicle traveling ahead and display it to the driver. The feature can be, for example, a vehicle roof rack, a roof rack box, a wheel carrier, truck bodies, in particular a forklift truck, a trailer of the detected vehicle, an object detachably arranged on the detected vehicle, and the like.

[0004] From DE 10 2019 202 580 A1, a generic method for operating a driver information system in an ego vehicle is known, in which an operating state of a lighting device of the ego vehicle is detected and a driver information display is generated and output.

[0005] DE 10 2018 203 946 A1 discloses a method for detecting unauthorized access to a means of transport or to its peripherals.

[0006] From DE 10 2018 201 395 A1 a method for monitoring a transport item arranged on a motor vehicle (10) by means of a transport item carrying device is known.

[0007] DE 10 2021 107 425 A1 discloses a method for automatic route planning and a motor vehicle configured for this purpose. In the method, a navigation destination is detected by a navigation device (18) of a main motor vehicle configured for route planning. Furthermore, it is automatically detected whether the main motor vehicle is carrying a small vehicle.

[0008] DE 10 2013 209 873 B4 proposes a device and a method for determining a possibility of passage for a vehicle under an obstacle, wherein a first sensor unit for measuring a clearance height under the obstacle and an evaluation unit are provided, wherein the evaluation unit compares the determined clearance height with a current vehicle height in such a way that a warning is issued in the event that the determined clearance height does not allow the vehicle to pass under the obstacle.

[0009] DE 10 2015 100 719 A1 discloses a method for operating a driver assistance system of a motor vehicle, in which a distance between the at least one distance sensor and an object is determined by means of at least one distance sensor which is arranged on and / or in a body component of the motor vehicle.

[0010] This means that there are numerous state-of-the-art driver assistance systems that can capture and process the surroundings of an ego vehicle, and display them as an image or graphic on a visual output device in the cockpit of the ego vehicle. This can identify vehicles ahead and their characteristics to alert the driver of the ego vehicle to potentially threatening dangerous situations caused by the vehicle ahead. It could be advantageous for the driver of the ego vehicle to be able to display comparable information for the ego vehicle in the ego vehicle.

[0011] 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 with currently known assistance systems.

[0012] This object is achieved by the method having the features of claim 1. Claims dependent on claim 1 advantageously develop the method.

[0013] One aspect of the invention relates to a method for improved customer communication between an ego vehicle and 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.

[0014] The roof rack can, in particular, be a roof bike rack. A bicycle can preferably be secured in the roof bike rack in an upright position. Upright means that the bicycle is standing on its tires in corresponding mounts on the roof bike rack, or that the bicycle is connected to the roof bike rack by the handlebars and seat, and the bicycle wheels are projecting essentially vertically upwards. One or more wheels can also be removed from the bicycle and transported separately from the bicycle frame. Finally, the bicycle frame can be connected to the roof bike rack without wheels by the front fork or front tires and the rear fork or rear tire. In this case, too, the removed wheel or wheels of the bicycle are transported separately.

[0015] The sensor system can include multiple vision sensors that monitor the immediate surroundings of the vehicle in front of, behind, and to the side of the ego vehicle; radar sensors that detect the distance of the ego vehicle to an object in front of, behind, and to the side of the ego vehicle; and other sensors that can, for example, receive GPS data, measure temperatures and humidity, and receive signals from traffic communication devices or other communication devices. The vision sensors can, for example, be image cameras, infrared cameras, or other sensors for detecting at least the contours of objects.

[0016] A graphic is not a realistic image, for example, captured by a camera. Rather, the graphic can be created using a graphics program. The graphics program can access saved data from individual graphic elements and combine them into an overall graphic based on the data reported by the sensors. The graphic elements can be basic geometric shapes, a graphic of the ego vehicle in any view, a graphic of a rear bike rack or graphics of different rear bike racks and a roof bike rack or different roof bike racks, a graphic that generally represents any bicycle and / or graphics that each represent a type or model of bicycle. A bicycle model can be considered to be an e-bike, a racing bike, a children's bike, a cargo bike, a mountain bike, and a leisure bike, although this list is not exhaustive.

[0017] According to the invention, the sensors detect the total number of bicycles secured in the rear bicycle rack and / or roof bicycle rack, and the total number of bicycles is displayed in the graphic of the ego vehicle with the rear bicycle rack and / or roof bicycle rack. 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 rack and / or roof bicycle rack. If only a single bicycle rack is connected to the ego vehicle, all displayed bicycles are located in this bicycle rack.

[0018] In one embodiment, the sensors can detect the number or total number of bicycles secured in the rear bike rack and / or the bicycles secured in the roof bike rack. The sensors can assign the detected bicycles to the rear bike rack and / or the roof bike rack and display the bicycles in the graphic of the ego vehicle with one bike rack or both bike racks in the corresponding bike rack.

[0019] If the sensors are configured to recognize the model of each individual bicycle, each model can be represented by a separate graphic or symbol. As already mentioned, the models can be assigned to the respective bike rack and, in one version, to a unique position within the bike rack. This means that for a bike rack with four-bike mounts, the bikes can be displayed in the graphic as they are arranged next to each other in the bike rack. This also applies if only a single bike is mounted in the bike rack.

[0020] In the graphic showing the ego vehicle with the bicycles, the maximum height of the vehicle-bike rack combination, its maximum width, and its maximum length can be clearly displayed for the driver. For a rear-mounted bike rack, a minimum vertical clearance from the road surface can also be specified. Further information can be displayed in the graphic, including a maximum permissible wind speed perpendicular to the direction of travel and / or a representation of the current wind direction and wind speed.

[0021] In one embodiment, for example, a color change and / or flashing of the graphic can indicate to the driver that the current situation, such as entering an underground parking garage, crossing a bridge with a critical clearance height, or a crosswind exceeding a specified limit, requires their full attention. At the same time, a warning tone can sound. If the ego vehicle is configured 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.

[0022] According to the invention, the bicycle or each of the bicycles comprises a communication device. Such a communication device can be advantageous for road safety by transmitting signals that can be received by other vehicles, such as cars, pickup trucks, motorcycles, or lorries, and converted into warning signals that alert the driver in the vehicle to the bicycle moving in the area. The communication device can, for example, receive location signals (e.g., GPS signals) and transmit its current position to a receiver continuously, in a timed manner, or upon request. The ego vehicle can receive the signals from the bicycle's communication device via a further sensor. In one embodiment, the signal can include information about the bicycle model. Preferably, the further sensor of the ego vehicle can detect multiple signals from bicycles simultaneously and differentiate between them.This means that the sensor can use the signals to detect the number / total number of transmitting communication devices and / or their exact arrangement in the bicycle carrier and preferably assign a model of the respective bicycle to each of the transmitting communication devices.

[0023] To ensure that the received signal(s) do not come from bicycles moving in the vicinity of the ego vehicle and also comprising a communication device, according to the invention, upon receipt of a communication signal from a bicycle, the sensor system, i.e., in particular, the vision sensors, confirms that no bicycle is detected in front of, behind, or next to the ego vehicle. A further indication that the received communication signal comes from a bicycle connected to the ego vehicle can be that the ego vehicle is moving at a speed greater than a predetermined limit and the received communication signal neither weakens nor disappears. The limit can be, for example, ≥70 km / h; for steep climbs and descents, for example in a mountainous region, a different limit 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 essentially identical despite, for example, changes in lane or direction over a preferably predetermined longer period of time.

[0024] The graphic displayed on the optical output device can be generated by a technical system of the ego vehicle. The technical system can include a control unit and a computer. The computer can run a graphics program that calculates the graphic.

[0025] In one embodiment, the control unit may comprise a memory that is connected to the computer and in which graphic elements for the ego vehicle, the bicycle carrier, the bicycle and / or bicycle models are stored, which can be used or combined by the graphics program of the computer to generate the graphics.

[0026] In one embodiment, in addition to depicting the ego-vehicle with the bike rack(s) and the bike(s), the graphic can display the maximum height of the ego-vehicle roof bike rack combination and / or the minimum distance of the rear bike rack from a road surface on which the ego-vehicle is parked or traveling. Furthermore, the graphic can display the current wind direction and wind strength.

[0027] 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 whose sensors are connected to the control unit, a memory in which graphic elements are stored, and a computer running a graphics program. The computer can calculate a graphic from the information sent to the control unit by the sensor system and the graphic elements stored in the memory and send it via the control unit to the optical output device for display.

[0028] The graphical representation of the ego-vehicle with the bike rack reminds the driver that a bike rack is connected to the ego-vehicle, especially on longer journeys. Optional acoustic and / or visual warnings of obstacles and / or critical weather conditions increase the driver's alertness in advance of critical situations. Optional information about the maximum dimensions of the combination of ego-vehicle, bike rack, and bike mounted in the bike rack, or the ground clearance in the area of ​​the rear bike rack, and / or the current wind direction and wind speed, enables the driver to make timely decisions to prevent damage to the bike, bike rack, and ego-vehicle.

[0029] All technical features described for the method according to the first aspect also apply to the technical system according to the second aspect, and vice versa.

[0030] The invention is explained in more detail below with reference to the figures. The figures show in detail: Fig. 1: a process as a flow chart; Fig. 2: a technical system of an ego vehicle for carrying out the procedure of Fig. 1; Fig. 3: Examples of graphical representations of the ego-vehicle with bicycle rack on an optical output device in the cockpit of the ego-vehicle.

[0031] The Fig. 1 shows a flowchart of a method by which the interaction between an ego vehicle 10 and the driver 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. In the following, essential aspects of the method are described using five method steps I, II, III, IV, V. The method steps I, II, III, IV, V can be carried out in the described order, but the order can also be changed. The reference symbols for technical features used to describe the method are all Fig. 2 taken.

[0032] When carrying out the method, in a first method step I, a bicycle rack 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 installation of a bicycle rack 40, 50 is confirmed manually by the driver in, for example, a submenu of an assistance system of the ego-vehicle 10. The bicycle rack 40, 50 can be a rear-mounted bicycle rack 40 connected to the rear of the ego-vehicle 10 or a roof-mounted bicycle rack 50 mounted on a roof of the ego-vehicle 10.

[0033] According to the current state of the art, the rear bicycle carrier 40 can be detected directly or immediately by the sensor system. The rear bicycle carrier 40 can be detected, for example, by a Visio sensor S2 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 processed by a computer of the technical system running a graphics program. The graphic showing the ego vehicle 10 with the rear bicycle carrier 40 is then output to the optical output device 60.

[0034] In the first method step I, the sensor system can further determine that a roof bike rack 50 is connected to the ego vehicle 10. Since known vehicles currently do not include a vision sensor that transmits an image of the vehicle roof to the cockpit, the detection of the roof bike rack 50 by the sensor system can only be done indirectly.

[0035] To enable this indirect detection of the roof bike rack 50, a bicycle 20, for example, can be arranged in the roof bike rack 50. This bicycle 20 comprises a communication device 70 that transmits signals that can be detected by a sensor S5 of the sensor system of the ego vehicle 10. In one embodiment, the communication device 70 can only be active when the bicycle 20 is moving. If the sensor system receives a signal from the communication device 70 while preparing for a trip, the technical system can calculate a graphic of the ego vehicle 10 with the roof bike rack 50. This graphic can be displayed on the optical output device 60.

[0036] In one embodiment, a graphic may be calculated and displayed on the optical output device 60 showing the ego vehicle 10 with a rear bicycle rack 40 and a roof bicycle rack 50.

[0037] When setting off with the ego vehicle 10, the roof bike rack 50 can be confirmed, for example, by the sensor system receiving the signal from the communication device 70 of the bicycle 20, while the ego vehicle 10 is simultaneously traveling at a speed above a predetermined limit. Even if the signal from the communication device 70 is received and the sensor system simultaneously detects no bicycle 20 in front of, next to, or behind the ego vehicle 10, the roof bike rack 50 can be indirectly confirmed. The same applies if the geodata of the ego vehicle 10 and the bicycle 20 remain essentially identical over an extended period of time with lane or direction changes of the ego vehicle 10.

[0038] 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 rack(s) 40, 50 and output this number in the graphic. It is assumed that each of the bicycles 20, or at least each of the bicycles 20 arranged in the roof bicycle rack 50, includes a communication device 70. The number or total number of bicycles 20 can be indicated as a number next to the graphic, or the number or total number of bicycles can be indicated by symbols.

[0039] In a third method step III, the bicycles 20 can be assigned to the respective bicycle carrier 40, 50 and shown in the graphic arranged in the corresponding bicycle carrier 40, 50. Instead, the receptacles for the bicycles 20 can be shown in the graphic of the bicycle carriers 40, 50. If, for example, two bicycles 20 are accommodated in a rear bicycle carrier 40 with three receptacles, two of the receptacles turn red, for example, while one of the receptacles remains green. The same applies to the roof bicycle carrier 50. The receptacles in which the bicycles 20 are actually arranged can be colored red.

[0040] 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 represented in the graphic as a symbol, for example in the form of an emoji.

[0041] In a fifth method step V, the graphic can be supplemented with additional information. This additional information can include, for example, a maximum height of the ego-vehicle-roof bike rack-bike combination, a minimum ground clearance of the rear bike rack 40 from the roadway, and / or information about a current wind direction and wind force or a maximum expected wind force at the time of travel in the area of ​​bridge crossings and / or treeless nature.

[0042] 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 limited clearance height, the ego vehicle 10 is being steered into an underground car park, or the weather forecast predicts gusts of wind with a strength that, at least when driving over a bridge, can lead to a sudden lateral offset and / or rocking of the ego vehicle 10 due to the larger attack surface transverse to the direction of travel.

[0043] The Fig. 2 shows a schematic diagram of a technical system 100 of an ego vehicle 10. The technical system 100 comprises a control unit 80, a sensor system with sensors S1, S2, S3, S4, S5, S6, S7, a computer 85, a memory 90, and an optical output device 60.

[0044] Sensors S1, S2, S3, S4 are vision sensors and / or radar sensors that monitor the surroundings of the ego vehicle 10. Sensors S1, S2, S3, S4 can at least detect, recognize (immobile object, vehicle, vehicle type, two-wheeler, type of two-wheeler) or identify objects in front of, next to, and behind the ego vehicle 10, and measure distances to the objects. The detected data is sent from sensors S1, S2, S3, S4 to control unit 80.

[0045] Sensor S5 is a first sensor that can receive signals from a communication device 70 included in a bicycle 20. Sensor S6 can be a second sensor for receiving geodata, and sensor S7 can be a third sensor and, for example, record current weather data. Sensors S5, S6, and S7 are also connected to the control unit 80.

[0046] In the illustrated embodiment, computer 85 is part of control unit 80 and can access the data acquired by sensors S1, S2, S3, S4, S5, S6, S7 via control unit 80. A graphics program runs on computer 85 that uses the data to calculate a graphic of the ego vehicle 10 with a bicycle rack 40, 50, and a bicycle 20. This graphic can then be displayed on an optical output device 60 in the cockpit of the ego vehicle within the driver's field of vision.

[0047] The computer 85 is connected to a memory 90. The memory 90 can be a vehicle-bound storage element or a cloud to which the ego vehicle 10 has access. Graphic elements that the computer 85 can use to create the graphic can be stored in the memory 90.

[0048] The Fig. 3 shows two examples of graphics G1, G2 as calculated by the computer 85 and output on the optical output device 60.

[0049] Graphic G1 shows a perspective view of the ego-vehicle 10 with a rear bicycle rack 40 and a bicycle 20 positioned in the rear bicycle rack 40. As can be clearly seen from Graphic G1, the attached rear bicycle rack changes the overall length of the combination of ego-vehicle 10 plus bicycle 20. This can be critical when driving into an underground car park. The entrance to the underground car park can be steep and abruptly transition to the level of the underground car park floor at the end. In particular, if the speed of the ego-vehicle 10 is too high in this situation, the rear bicycle rack 40 can touch down and be damaged. This effect can be intensified by the compression of the ego-vehicle 10 at the transition from the steep descent to the flat ground and / or a sudden braking of the ego-vehicle 10 at this moment.

[0050] In addition, carrying the bicycle 20 in the rear bicycle rack 40 changes the drag coefficient of the ego vehicle 10, resulting in a shorter range due to higher power consumption for a battery-powered motor or higher fuel consumption for a combustion engine. The maximum range of the network can change depending on the energy reserves of the ego vehicle 10 and the profile of the planned route. This can be displayed to the driver of the ego vehicle 10 in graph G1.

[0051] Graphic G2 shows the ego-vehicle 10 with a roof bike rack 50 and a bicycle 20 without a front wheel, which is mounted in the roof bike rack 50. The total height of the combination of ego-vehicle 10 plus roof bike rack 50 plus bicycle 20 can also be displayed to the driver of the ego-vehicle 10 in graphic G2. Based on the determined total height, the navigation system can check the route for any hazards with height restrictions and inform the driver of the ego-vehicle 10 in a timely manner that they are approaching a hazard.

[0052] In this combination, the drag coefficient of the ego-vehicle 10 also changes noticeably, while at the same time, the surface area exposed to wind blowing perpendicular to the direction of travel increases. This larger surface area can cause the ego-vehicle 10 to suddenly shift sideways, for example, when crossing a bridge. The additional surface area created by the bicycle also exerts a leverage effect on the ego-vehicle 10, so that in strong gusts the ego-vehicle 10 can be set into a rocking motion perpendicular to the direction of travel and, in extreme cases, tip over. Therefore, it can be advantageous if the graph G2 also displays a wind direction and a maximum wind speed, for example, if a corresponding bad weather warning is announced on the traffic radio.
