Abstract
Description
Technical Field
[0001] This invention relates to a method for handling traffic situations with restricted passage geometry. Furthermore, this invention relates to a vehicle configured to perform at least a portion of the method according to the invention. Background Technology
[0002] In road traffic, passage is often possible only with limitations imposed by vehicle geometry. Passage height or width is frequently restricted when traveling through tunnels, narrow roads, or parking garages. Currently, signs indicate these restrictions in most cases. However, these signs are often installed immediately before the obstacle and may be overlooked or obscured. Therefore, in traffic situations, an immediate assessment by the driver of whether their vehicle's dimensions allow passage or not is often necessary. Methods for identifying restricted passage geometry and comparing it with vehicle dimensions are known from DE 10 2014 221 895 A1, DE 10 2016 202 361 A1, and DE 10 2018 206 667 A1.
[0003] However, drivers may not be able to quickly ascertain the relevant dimensions of their vehicles. Drivers of rented or borrowed vehicles, as well as those using shared cars, frequently cause accidents due to misjudgments of dimensions. Even for vehicle owners, however, dimensions are variable and depend on many factors, often making them difficult to estimate easily.
[0004] The height of a vehicle is variable, for example, due to roof attachments, rear attachments, or an adjustable chassis. Width is described in vehicle documentation without exterior mirrors. Therefore, the actual width of a vehicle with exterior mirrors is difficult to estimate. Here, the width varies depending on the position of the mirrors, which may be folded out or recessed, or when, for example, additional trailer mirrors are installed. Furthermore, trailers can significantly affect the vehicle's dimensions. A method for determining the current dimensions of a vehicle is known from DE 10 2019 205 166 A1. Summary of the Invention
[0005] The present invention is based on the objective of enriching the prior art and overcoming or at least reducing the disadvantages therefrom, and providing an improved method for handling traffic situations with restricted passage geometry.
[0006] A first aspect of the invention relates to a method for acquiring a vehicle in a traffic situation with a restricted passage geometry. In the sense of this disclosure, the vehicle is preferably a car or truck equipped with an internal combustion engine, an electric motor, or a hybrid engine. In the sense of this disclosure, the restricted passage geometry is preferably an architectural or natural feature of the vehicle's surrounding environment that makes passage possible only for vehicles of a specific size. Restricted passage geometry can be, for example, a tunnel, a bridge over a lane, an underpass, or an entrance to an interior courtyard or parking garage.
[0007] In the first step of this method, sensor values relative to the vehicle's surrounding environment are acquired. These sensor values are acquired using at least one sensor configured to acquire sensor signals relating to the vehicle's surrounding environment. The at least one sensor is preferably a camera, lidar sensor, radar sensor, sonar, laser, and / or ultrasonic sensor.
[0008] In another method step, the restricted passage geometry is further identified using at least one sensor value. Preferably, a distance measurement is performed using at least one sensor value to facilitate the identification of the restricted passage geometry. Furthermore, preferably, the restricted passage geometry is identified using image processing for object recognition using at least one sensor value, and particularly preferably using deep learning-based image processing.
[0009] Following this, the method involves determining a restricted passage geometry based on at least one sensor value. In the context of this disclosure, the restricted passage geometry is preferably defined by the internal dimensions of the geometry. This passage preferably involves a restricted area of passage through the geometry. Furthermore, the location of the restricted passage geometry is determined. Preferably, the geographic coordinates of the geometry are determined in the form of GPS data.
[0010] As another method step, the method includes the determination of at least one other vehicle with a dimension exceeding the determined extension and / or a route leading to a location with restricted access geometry. Preferably, the dimensions and / or routes of the multiple vehicles are determined based on a cooperative awareness message (CAM) sent by the multiple vehicles. Preferably, the determined extension is compared with a determined dimension, and the dimension of at least one other vehicle is determined from among the multiple vehicles when its dimension exceeds the determined extension. Furthermore, preferably, a determined location is compared with a determined route, and at least one other vehicle is determined from among the multiple vehicles when its route leads to that location. In another step, preferably, the message is transmitted to the determined at least one other vehicle.
[0011] In another step of the method, a message relating to the determined extension and position of the restricted access geometry for output by at least one other vehicle is generated. Furthermore, the generated message is transmitted in this method to at least one other vehicle, a server, and / or a roadside unit. Preferably, this transmission is implemented according to the C-V2X standard or according to the WLAN protocol IEEE 802.11p. More preferably, this transmission is implemented using a Cooperative Awareness Message (CAM). Preferably, the message is delivered by the server and / or the roadside unit to at least one other vehicle. More preferably, the message is stored by the server and / or the roadside unit. By repeating the method according to the invention, an overview of the extension and position of multiple restricted access geometries in the surrounding environment can thus be advantageously generated.
[0012] The method according to the invention advantageously ensures that the restricted passage geometry of the vehicle is identified in advance. These restrictions are advantageously identified even when warning signs are missing or obscured. Another advantage of the method is that the current extent of the restricted passage geometry is acquired and transmitted, while warning signs always only describe values measured at the time of setup. Furthermore, the method advantageously results in the message being transmitted only to the vehicle involved by the restricted passage geometry. Therefore, energy and resources are advantageously saved and unnecessary driver distraction is avoided.
[0013] In a preferred embodiment of the method according to the invention, the determination of the extension includes determining the maximum passing height, maximum passing width, and / or the three-dimensional driving channel using at least one sensor value. The maximum passing height or passing width is preferably a length specification that cannot be exceeded by the height or width of the vehicle, in order to ensure accident-free passage through the restricted driving geometry. The three-dimensional driving channel is preferably determined as a negative value of the restricted driving geometry. For vehicles capable of traversing the three-dimensional driving channel without leaving the lateral boundaries of the channel, accident-free passage through the restricted driving geometry is ensured.
[0014] Another aspect of the invention relates to a method for vehicle control in traffic situations with restricted passage geometry. As a step, the method includes receiving a message from another vehicle, wherein the message contains the location and extent of the restricted passage geometry. Preferably, the message is generated and transmitted by the other vehicle using the method according to the invention, which is based on the surrounding environment of the vehicle in the traffic situation with restricted passage geometry. The message is preferably a message according to the C-V2X standard or the WLAN protocol IEEE 802.11p. Preferably, the message is received directly by the other vehicle or indirectly via a server and / or roadside unit.
[0015] In another method step, the restricted passage geometry is compared to the vehicle's dimensions. In other words, this method step checks whether the vehicle is suitable for passage through the restricted passage geometry.
[0016] In this method, a report is generated based on the comparison and output via the vehicle's output device. The report preferably includes notification that passage through the restricted geometry is possible when the comparison concludes that the vehicle's dimensions are below the extension. Alternatively, preferably, the report is not generated and output when the comparison concludes that the vehicle's dimensions are below the extension. The report preferably includes notification that passage through the restricted geometry is impossible when the comparison concludes that the vehicle's dimensions exceed the extension. The output device is preferably a display, such as, for example, the vehicle's central display, a display of in-vehicle electronic equipment, or the vehicle's head-up display. The report is preferably output as text and / or graphic symbols via the output device. Furthermore, preferably, the report is output as an augmented reality (AR) display overlaid by the output device onto the vehicle's real surrounding environment.
[0017] A preferred implementation scheme involves comparing the location of a restricted passage geometry with the vehicle's current route. Preferably, in this comparison, it is determined whether the restricted passage geometry is on the vehicle's current route. Additionally or alternatively, the vehicle's current dimensions are determined by the vehicle, and the extension of the restricted passage geometry is compared with the vehicle's current dimensions. In other words, it is checked whether the vehicle, with its current dimensions, is suitable for navigating the extension of the restricted passage geometry. Preferably, the current dimensions are determined by the vehicle based on current vehicle settings read from the vehicle. Preferably, the vehicle's current width is determined based on the folded-in or flip-out state of the vehicle's exterior rearview mirrors. Furthermore, preferably, the vehicle's current height is determined based on the vehicle's current chassis settings. Furthermore, preferably, the current dimensions are determined based on user input. The user input preferably includes information relative to at least one attachment located at the vehicle.
[0018] Based on this comparison, a report for the vehicle's output devices is generated and output. This report preferably includes a notification that continued driving of the vehicle can be achieved safely when the comparison concludes that the vehicle's current dimensions are below the extended and / or restricted passage geometry is not on the current route. Alternatively, preferably, this message is not generated and output when the comparison concludes that the vehicle's current dimensions are below the extended and / or restricted passage geometry is not on the current route. The report also preferably includes a notification that continued driving of the vehicle cannot be achieved safely when the comparison concludes that the vehicle's current dimensions exceed the extended and restricted passage geometry on the current route. Preferably, when the comparison concludes that the restricted passage geometry is on the current route, at least one alternative route is searched for by the vehicle. This at least one alternative route is preferably compared with an overview of multiple restricted passage geometries in the surrounding environment stored on a server and / or roadside units. Preferably, the restricted access geometry is not located on at least one of the alternative routes, and its extension is less than the size of the vehicle. Preferably, the report additionally includes a suggestion for at least one alternative route.
[0019] Another preferred implementation form includes the determination of at least one vehicle configuration relative to the current size of the vehicle. Preferably, at least one vehicle configuration is determined that increases the current size of the vehicle compared to other possible configurations, such as, for example, flip-up exterior mirrors, chassis configurations that increase vehicle height, or accessories located on the vehicle. The accessory is preferably a trailer or the body of the vehicle. Preferably, further changes in the relevant vehicle configuration are determined that cause the vehicle size to be lower than the restricted extensions through geometry.
[0020] Preferably, a prompt relating to relevant vehicle settings is output via the vehicle's output device. This prompt preferably further includes changes to the relevant vehicle settings. In other words, the prompt preferably includes settings that can be implemented at the vehicle to enable driving through restricted geometry, such as, for example, folding in exterior rearview mirrors, adjusting chassis settings to lower the vehicle height, or removing accessories. Furthermore, preferably, the relevant vehicle settings are automatically matched by the vehicle. In other words, preferably, changes to the relevant vehicle settings are automatically performed by the vehicle itself.
[0021] In a further preferred implementation scheme, the current dimensions of the vehicle are determined by the determination of at least one accessory located in the vehicle and the determination of the dimensions of at least one accessory by a web server and / or by invocation of at least one accessory. Preferably, at least one accessory located in the vehicle is determined by means of at least one of the vehicle's own sensors and / or user input. Furthermore preferably, at least one accessory is configured to communicate with the vehicle and is determined by means of communication. Preferably, the dimensions of at least one accessory are invoked by a lookup table (LUT) stored on a web server and / or within the vehicle itself. Furthermore preferably, the dimensions of at least one accessory are invoked by the accessory via communication, particularly preferably by at least one accessory.
[0022] Another aspect of the invention relates to a vehicle, particularly a passenger car equipped with an internal combustion engine, an electric motor, or a hybrid powertrain, configured to perform the aforementioned method for vehicle control in traffic situations with restricted traffic geometry. The vehicle has a communication module configured to receive messages relating to the position and extent of the restricted traffic geometry.
[0023] Furthermore, the vehicle has a control unit preferably configured to determine the vehicle's dimensions, particularly preferably to determine the vehicle's current dimensions, compare these dimensions with a restricted extension through the geometry, and determine a report based on this comparison. Additionally, the vehicle has an output device configured to output the report.
[0024] In a preferred embodiment, the vehicle is further configured to perform the aforementioned method according to the invention for acquiring the surrounding environment in traffic situations with restricted passage geometry. For this purpose, the vehicle preferably further includes sensors configured to acquire at least one sensor value relative to the vehicle's surrounding environment.
[0025] Furthermore, the control unit is preferably configured to identify the restricted passage geometry using at least one sensor value, determine the extension of the restricted passage geometry using at least one sensor value, and determine the location of the restricted passage geometry. Additionally, the communication module is preferably configured to transmit messages relating to the extension and location of the restricted passage geometry to another vehicle, a server, and / or a roadside unit. In other words, the control unit, and therefore the vehicle, is also configured to perform the aforementioned method for acquiring the surrounding environment in traffic situations with restricted passage geometry.
[0026] In a further preferred design of the vehicle according to the invention, the control unit is further configured to determine at least one vehicle setting relevant to the current size of the vehicle. Furthermore, the control unit is preferably configured to output prompts relating to the relevant vehicle settings via the vehicle's output devices and / or automatically match the relevant vehicle settings.

[0040] Figure 1 A schematic flowchart of the method according to the invention for acquiring the surrounding environment in a traffic situation with restricted access geometry is shown in one exemplary implementation scheme.
[0041] In the first step S1, at least one sensor value for the vehicle's surrounding environment is acquired using at least one sensor. The second step S2 involves the restricted identification of geometric structures, particularly bridges or tunnels, using the at least one sensor value acquired in the first step S1.
[0042] In the third step S3, the extension of the restricted passage geometry follows, based on the determination of at least one sensor value acquired in the first step S1 and the determination of the location of the restricted passage geometry. Here, the extension is specifically determined as the maximum passage height and maximum passage width of the restricted passage geometry, and the location is determined as the geographic coordinates of the passage geometry in the form of GPS data.
[0043] Based on the extension and position determined in the third step S3 of the restricted passage geometry, a message for output by at least one other vehicle is generated in the fourth step S4. This at least one other vehicle is specifically identified as the vehicle involved in the restricted passage geometry, whose dimensions therefore exceed the extension or its route leading to that position.
[0044] In the fifth step S5, the message generated in the fourth step S4 is then transmitted to at least another vehicle, particularly by means of C-V2X or WLANp communication, directly or via a server or roadside unit.
[0045] Figure 2 A schematic flowchart of the method according to the invention for vehicle control in traffic situations with restricted passage geometry is shown in one exemplary implementation scheme.
[0046] In the sixth step S6, the vehicle receives a message containing the restricted position and extension through the geometry. This message is received by another vehicle, and specifically, is the message generated in the fourth step S4 and transmitted in the fifth step S5.
[0047] Then, in step S7, the dimensions of the vehicle are compared with the restricted geometric extension. These dimensions are, in particular, the current dimensions of the vehicle, which are determined by the vehicle itself. Additionally, the position is compared with the vehicle's current route. Furthermore, the vehicle settings associated with the current dimensions are determined.
[0048] In step S8, a report is generated based on the performed comparison and output through the vehicle's output device. In this case, the report is output specifically because the comparison performed in step S7 concludes that the vehicle's dimensions exceed the permitted range and its position is on the vehicle's current route. The report specifically includes indications that continued travel on the current route is not feasible without danger, a description of alternative routes, and possible vehicle configurations to facilitate travel through restricted geometry.
[0049] Figure 3 A schematic diagram, particularly a block diagram, of an exemplary vehicle 1, is shown, especially a dual-rail motor vehicle equipped with an internal combustion engine, an electric motor, or a hybrid powertrain. Vehicle 1 is specifically configured to perform a method according to the invention for acquiring the surrounding environment in traffic situations with restricted passage geometry, as previously described and in… Figure 1 As shown in [the previous description]. Furthermore, vehicle 1 is configured to perform the method according to the invention for vehicle control in traffic situations with restricted passage geometry, as previously described and in [the following description]. Figure 2 As shown in the document.
[0050] For this purpose, vehicle 1 initially has multiple first sensors, specifically first sensor 11, second sensor 12, and third sensor 13. The first sensors 11, 12, and 13 are configured to acquire data about the surrounding environment of vehicle 1 and include, for example, cameras for acquiring images of the surrounding environment of vehicle 1 and / or distance sensors, such as ultrasonic sensors, for acquiring distances relative to objects surrounding vehicle 1. The first sensors 11, 12, and 13 transmit the sensor values they acquire relative to the vehicle's surrounding environment to a control unit 40 of vehicle 1. The control unit 40 is configured to identify restricted passage geometry using the sensor values, determine its extension and position, and thereby generate messages for output in a second vehicle 1b. For this purpose, the control unit 40 has an internal memory 41 and a CPU 42, which communicate with each other, for example, via a suitable data bus.
[0051] Furthermore, vehicle 1 has a communication module 30 with a memory 31 and one or more repeaters or transceivers 32. The repeater 32 is a radio-, WLAN-, GPS-, or Bluetooth transceiver or similar, particularly configured for communication within a communication network. The repeater communicates with the internal memory 31 of the communication module 30, for example, via a suitable data bus. With the aid of the repeater 32, for example, the current location of vehicle 1 can be determined through communication with GPS satellites 51 and stored in the internal memory 31. Furthermore, the communication module 30 is configured to communicate with a second vehicle 1b via V2V communication, particularly also via the communication network 52. Additionally, the communication module 30 may also be configured to communicate with a server of the communication network 52.
[0052] The communication module 30 also communicates with the control unit 40. Specifically, it transmits received data to the control unit and / or receives data to be sent by the control unit. Therefore, the control unit 40 can transmit generated messages to the second vehicle 1b via the communication module 30. Furthermore, the control unit 40 can receive messages from the second vehicle 1b via the communication module 30, which contain information about the restricted position and extension of the geometric structure.
[0053] The communication network 52 is preferably a network based on 3GPP standards, such as LTE, LTE-A (4G), or 5G communication networks. Furthermore, the communication network may be designed to operate according to or based on the following standards: High-Speed Packet Access (HSPA), Universal Mobile Telecommunications System (UMTS), UMTS Terrestrial Radio Access Network (UTRAN), Evolved UTRAN (e-UTRAN), Global System for Mobile Communications (GSM), Enhanced Data Rate GSM Evolution (EDGE), and GSM / EDGE Radio Access Network (GERAN). Alternatively or additionally, the communication network 52 may also be constructed according to one of the following standards: Global Microwave Access Interoperability (WIMAX) network IEEE 802.16, Wireless Local Area Network (WLAN) IEEE 802.11. Also preferably, the communication network 52 uses one of the following coding methods: Orthogonal Frequency Division Multiple Access (OFDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), Wideband CDMA (WCDMA), Frequency Division Multiple Access (FDMA), or Space Division Multiple Access (SDMA), etc.
[0054] Furthermore, the control unit 40 is configured to compare the restricted extension of the geometry with the dimensions of vehicle 1 and the position with the current route of vehicle 1. For this purpose, the control unit 40 can determine the current dimensions of vehicle 1 based on sensor signals from second sensors 21, 23 (particularly a fourth sensor 21 monitoring the first vehicle component 22 and a fifth sensor 23 monitoring the second vehicle component 24). The first vehicle component 22 is in particular the exterior rearview mirrors of vehicle 1, and the control unit 40 can identify the folded-in or flip-out state of the rearview mirrors by means of the fourth sensor 21. The second vehicle component 24 is in particular the adaptive chassis, and the control unit 40 can identify its state by means of the fifth sensor 23. Furthermore, the control unit 40 can determine the vehicle settings relevant to the current dimensions.
[0055] Furthermore, the control unit 40 can generate a report based on this comparison and output it through the output device 50 of the vehicle 1. This report may include, for example, indications that continued travel on the current route is not safe, a description of alternative routes, and vehicle settings that can be made to enable travel through restricted geometry. The control unit 40 can also automatically adjust vehicle settings by sending control signals to vehicle components 22, 14.
[0056] The control unit 40 is thus in communication connection with at least the first sensors 11, 12, 13, the second sensors 21, 23, the vehicle components 22, 24, the output device 50, and the communication module 30, for example via one or more corresponding CAN connections, one or more corresponding SPI connections, or other suitable data connections.
[0057] Figure 4 The method steps S1, S2, S3 of the method according to the invention for acquiring the surrounding environment are shown in the form of an exemplary execution scheme. A first vehicle 1a is shown, which is in front of a restricted passage geometry 60, particularly a bridge 60 restricting passage on a road. By means of a sensor 11, the vehicle 1a acquires sensor values and identifies the restricted passage geometry 60 with an extension 61 by means of the sensor values. The vehicle 1a is configured to determine the extension 61, particularly the passage width 62 and passage height 63 of the extension 61, and to determine the position of the restricted passage geometry 60 by means of the sensor values.
[0058] Figure 5 The illustration shows the determination, generation, and transmission of method steps S3, S4, and S5 according to the method of the invention based on the acquisition of the surrounding environment in an exemplary execution scheme. (As shown in...) Figure 4As shown from another angle, vehicle 1a determines the extension 61 and position of the restricted passage geometry 60 based on at least one sensor value from sensor 11. The vehicle then generates a message for output to another vehicle, relating to the extension 61 and position. This is followed by transmission of the message to the other vehicle, here in particular the second vehicle 1b. In this exemplary implementation, the message is sent to roadside unit 53 and received by roadside unit 53 from the second vehicle 1b. The transmission thus performed is shown by thin dashed lines. In particular, the message is additionally stored by roadside unit 53 and an overview of the positions 64 and extensions 61 of the multiple restricted passage geometries 60 in the surrounding environment 54 is generated based on the multiple messages. Figure 6 The image is shown in the middle.
[0059] exist Figure 5 In the scenario shown, the extension is received specifically by the second vehicle 1b and not by the third vehicle 1c. The second vehicle 1b here is, in particular, a truck, which has a size exceeding the extension 61 and whose route leads to position 64. The second vehicle 1b is thus involved by the restricted passage geometry 60. Therefore, the message is transmitted to the second vehicle 1b to enable the output of the second vehicle 1b based on this message, which is described in detail below. The third vehicle 1c here is a sedan with a smaller size, so the restricted passage geometry 60 is irrelevant to the third vehicle 1c. The method according to the invention thus advantageously results in the driver of the third vehicle 1c not being distracted by outputs based on the extension 61 that do not involve it.
[0060] The second vehicle 1b compares the restricted extension 61 of the geometry 60 with the current size of the vehicle 1b and compares its position 64 with its current route. Furthermore, the vehicle settings relevant to the current size are determined by the vehicle 1b.
[0061] Vehicle 1b then generates a report based on this comparison and outputs it through output device 50. The outputs A1, A2, and A3 of vehicle 1b are... Figure 7 The following is an exemplary implementation of the described method. The output device 50 of the second vehicle 1b, particularly the head-up display, is shown. A restricted passage geometry 60 exists before vehicle 1b. The comparison performed indicates that the vehicle's dimensions exceed the extension and position 64 is on the vehicle's current route. Therefore, the report specifically includes a warning that continued travel on the current route is not safe, which is output as a first output A1 by means of augmented reality (AR). The first output A1 is particularly illustrated as an extension 61, highlighted in red and accompanied by a warning symbol.
[0062] The second output A2 also includes a report describing the identified alternative routes. These alternative routes are specifically based on... Figure 6 The overview shown is generated so that its extension is below the size of the second vehicle 1b, and the restricted passage geometry 60 is not on the alternative route. Figure 7 In the scenario shown, the vehicle settings, particularly the adaptive chassis settings, are additionally determined, which lowers the height of vehicle 1b and thus makes passage possible. Based on the determined settings, a third output A3 is output. The driver of the second vehicle 1b can advantageously and quickly and clearly learn through outputs A1, A2, and A3 that driving through the restricted passage geometry 60 is not possible without danger, and can decide whether to use an alternative route or to match the vehicle settings.
