Description

[0001] The invention relates to a guidance device for at least one vehicle, in particular an at least partially automated vehicle, which is preferably designed as a signal vane.

[0002] In road traffic, the problem often arises that an authorized person, such as a police officer, outside a vehicle, e.g., from the side of the road, wants to give instructions to a driver that require a corresponding adjustment of the vehicle's behavior. In a common situation, a police officer attempts to force a vehicle to stop by using a so-called signal baton.

[0003] Such signal batons are known in various designs from the prior art. For example, DE 373 094 A discloses a signal baton equipped with an illumination device. DE 87 06 830 U1 also discloses an illuminated police baton with a spotlight for illumination purposes.

[0004] With these types of traffic control devices, a necessary condition is that the driver of the vehicle monitors the traffic with full attention in order to detect the authorized person with the traffic signal at the side of the road as early as possible when driving in their direction. Furthermore, the driver of the vehicle must correctly interpret the gestures or movement patterns of the authorized person in order to adapt the vehicle behavior accordingly or to carry out an action indicated by the authorized person. This creates uncertainty for both the driver and the authorized person giving the instruction, as the authorized person can easily be overlooked and / or the movement pattern misunderstood.

[0005] Especially in partially, highly or even fully automated vehicles, the driver is no longer fully aware of the traffic situation, as the lateral and longitudinal guidance is at least partially taken over by a driver assistance system in the vehicle.

[0006] Systems that can recognize user gestures are known from the state of the art, e.g., from US Pat. No. 7,877,707 B2. It is also known that emergency vehicles can warn vehicles ahead so that they can evade the vehicle even if the emergency vehicle is not yet visible or audible; see Car2Car Communication Consortium (www.car-to-car.org).

[0007] DE 10 2008 042 809 A1 discloses a communication system with a handheld device for wirelessly delivering instructions in the form of data regarding behavior in traffic, and with a receiver unit that receives the data and converts the data content for perception by a road user. The handheld device is shaped like a traffic baton and has a position / motion sensor that provides information about the position of the handheld device in space. If a traffic police officer changes the position of the handheld device, this is detected by the position / motion sensor, and data is sent from the handheld device to the receiver units located in the vehicle.

[0008] Based on this prior art, it is an object of the invention to provide a device and a method that ensures that a driver and / or a driver assistance system takes note of instructions that an authorized person signals by movement.

[0009] This object is achieved by the guidance device according to claim 1, the guidance system according to claim 8, and the method for guiding at least one vehicle according to claim 13. Advantageous embodiments are claimed in the subclaims.

[0010] The guidance device and method according to the invention have the advantage that the instructions given by a person, in particular an authorized person, using movement patterns or gestures can be transmitted to vehicle A and / or the driver of this vehicle A using common signal transmission methods. The instruction transmitted in this way can then be output to vehicle A, in particular to a driver assistance system of vehicle A. Furthermore, the instruction can also be output to the driver visually, acoustically, or in any other way. This ensures that a driver assistance system controlling vehicle A or the driver of vehicle A takes note of the instruction. This process is independent of whether there is a line of sight between the person executing the movement patterns and vehicle A, or whether the driver is monitoring the traffic or distracted by other activities.

[0011] A user interface within the meaning of the invention is a location and / or a device with which a person comes into contact with a device.

[0012] An instruction within the meaning of the invention is a note, a warning and / or an optional or mandatory instruction to a vehicle A or a driver assistance system and / or the driver.

[0013] A transmission module within the meaning of the invention is any type of transmitter that can transmit information wirelessly and / or wired to a receiving module. The transmission can be a unicast connection, a broadcast connection, an anycast connection, a multicast connection, or even a geocast connection, or a combination of the aforementioned connections.

[0014] A central computer within the meaning of the invention is any type of centrally arranged computing unit which is interposed in particular between a control device according to the invention and a control unit, preferably a so-called backend.

[0015] A vehicle within the meaning of the invention is any type of air, land, water or space vehicle, but in particular a motor vehicle.

[0016] A partially automated vehicle within the meaning of the invention is a vehicle in which a driver assistance system takes over the lateral and longitudinal guidance at least for a certain period of time and / or in specific situations, whereby the driver must permanently monitor the system and be ready to take over complete control of the vehicle at any time.

[0017] A highly automated vehicle, as defined by the invention, is a vehicle in which a driver assistance system assumes lateral and longitudinal guidance for a certain period of time and / or in specific situations. The driver does not have to monitor the system during this time, but is prompted to take over the driving task with sufficient time reserve if necessary. The limitations of the driver assistance system are recognized by the system itself. However, the driver assistance system is not capable of bringing about a minimal-risk state from every initial situation.

[0018] A fully automated vehicle within the meaning of the invention is a vehicle in which a driver assistance system completely assumes lateral and longitudinal guidance in a defined application scenario; the driver does not have to monitor the driver assistance system. Before leaving the application scenario, the driver assistance system requests the driver to assume the driving task, preferably with sufficient time in reserve. If this does not occur, the system returns to the risk-minimal driver assistance system state. Limits of the driver assistance system are preferably all detected by the driver assistance system itself; more preferably, the driver assistance system is capable of returning to the risk-minimal driver assistance system state itself in all situations.

[0019] A hand module within the meaning of the invention is any type of device, in particular a front hand, which is suitable for actuating the device according to the invention by a person.

[0020] A movement pattern within the meaning of the invention is a specific movement or sequence of movements used to convey information from one person to another person or a device, in particular a gesture. This can be performed, in particular, by movements of the arms, hands, and head and can be supplemented by sounds, e.g., the sound of a whistle.

[0021] A control command within the meaning of the invention is any type of request to intervene in the driving state of the vehicle.

[0022] A module within the meaning of the invention can be both a hardware element and a software element.

[0023] In an advantageous embodiment, the guidance device is a hand-held module, in particular a signaling device and / or a portable computer, in particular a smartphone, and the sensor has at least one acceleration sensor, a position sensor and / or a rotation rate sensor for detecting the at least one movement pattern of the person.

[0024] The advantage of designing the guidance device as a signaling device is that even drivers of vehicle A who do not yet have the technology to receive instructions can be informed using the classic method of visually recognizing the movement patterns of a person at the side of the road. The guidance device according to the invention is thus backward compatible with the previous method of traffic guidance. It is also particularly advantageous to install guidance software, for example, on a smartphone or computer watch, which the person giving the instructions usually carries with them. Thus, the function as a guidance device is just one of many conceivable functions of this portable computer and can be activated as needed.

[0025] In a further advantageous embodiment, the guidance device has a second user interface for feedback of the detection of the at least one movement pattern, in particular a vibrator and / or a visual display.

[0026] Through this second user interface, the person giving the instructions can receive confirmation of the successful execution of an instruction. The second user interface can be identical to the first user interface.

[0027] In a further advantageous embodiment of the guidance device, the sensor has at least one image sensor A for detecting the at least one movement pattern.

[0028] The image sensor A can be present alternatively or in addition to other sensors in order to detect a movement pattern or to confirm a detected movement pattern.

[0029] In a further advantageous embodiment, the guidance device further comprises a distance module for determining the distance to the at least one vehicle, in particular a radar or lidar, and / or a direction module for determining the direction in which the guidance is taken, in particular a compass.

[0030] These modules are used in particular to identify the vehicle A that the person performing the movement patterns intends to guide.

[0031] In a further advantageous embodiment, the guidance device has a position determination module, in particular a satellite navigation system.

[0032] Determining the position of the guidance device serves, in particular, to define an area in which vehicles A are to be guided. Furthermore, this position can be used to authorize the use of the guidance device only in a specific geographical area.

[0033] In a further advantageous embodiment, the guidance device has an authentication module for identifying an authorized person, in particular a biometric sensor, a radio recognition system and / or an RFID recognition system.

[0034] Such an authentication module prevents the use of the guidance device by persons not authorized to guide traffic, thus effectively limiting the group of users.

[0035] The aspects of the invention first described above and the associated features disclosed for further developments of the guidance device also apply accordingly to the aspects of the invention described below and the associated developments of the guidance system and the method for guiding a vehicle A. Conversely, the features disclosed for the following aspects of the invention and for the further developments of the guidance system and the method also apply accordingly to the aspects of the invention described above and the associated developments of the guidance device.

[0036] With the guidance system according to the invention, control commands based on the instructions can be issued directly to vehicle A or its driver assistance system provided for lateral and longitudinal guidance, or directly to the driver. This ensures that the driver assistance system or the driver acknowledges an instruction and can respond.

[0037] In an advantageous embodiment of the control system, the control unit has a third user interface which can transmit the at least one control command to the driver visually, audibly and / or haptically.

[0038] In a further advantageous embodiment, the control system has at least one image sensor B, in particular as part of the control unit.

[0039] With the image sensor B, a vehicle can be perceived and classified and / or identified according to type, size, color, license plate and / or other characteristics of the vehicle.

[0040] In a further advantageous embodiment, the control unit has a transmission module for reporting a successful transmission of the at least one instruction for the at least one vehicle A to the control device.

[0041] This feedback enables the person giving instructions to determine whether the message has reached vehicle A or its driver assistance system and / or the driver and whether they can expect a response from the driver assistance system or the driver.

[0042] In a further advantageous embodiment, the control system has a central computer via which the control device can communicate with the at least one vehicle.

[0043] In an advantageous embodiment, the method comprises the following work step: authenticating the person, wherein at least the transmission of a signal is only carried out if the person is a person authorized to use the guidance device, and / or wherein at least one notification is sent, in particular to a person authorized to use the guidance device, if the person is not authorized to use the guidance device.

[0044] In a further advantageous embodiment, the method comprises the following work step: checking whether an emergency vehicle of the person is located within the radius, preferably within a radius of 100 m, more preferably within a radius of 70 m, even more preferably within a radius of 50 m, even more preferably within a radius of 30 m and particularly preferably within a radius of 10 m, wherein at least the transmission of an instruction is only carried out if the guidance device is located within the respective radius.

[0045] The method according to the invention comprises the following work step: determining the at least one vehicle A from a plurality of vehicles, in particular automated vehicles, in particular by means of a distance determination from the person to the plurality of vehicles and / or a visual recognition, further in particular via a license plate recognition.

[0046] In a further advantageous embodiment of the method, the transmitted instruction further comprises information for determining the at least one vehicle A, in particular an identification for the at least one vehicle A and / or descriptive geo-data of the area in which the at least one vehicle A is to be guided, in particular a latitude / longitude radius and / or a geographical shape.

[0047] In a further advantageous embodiment, the method comprises the following work step: interpreting the instruction to derive at least one control command to the at least one vehicle A and / or a driver of the at least one vehicle A and outputting the at least one control command to the at least one vehicle A and / or its driver.

[0048] In a further advantageous embodiment, the method comprises the following work step: Reporting back a successful derivation of an instruction from the at least one movement pattern by the guidance device to the person and / or by the at least one vehicle A to the guidance device and / or the central computer.

[0049] In a further advantageous embodiment of the method, the identification is an identification code and / or information about the vehicle weight, the vehicle type, the license plate, the vehicle position and / or the direction of travel of the at least one vehicle A.

[0050] Further features, advantages, and possible applications of the invention will become apparent from the following description in conjunction with the figures. They show: Fig. 1 partially schematically shows an embodiment of the guiding device according to the invention. Fig. 2 partially schematically a control system according to the present invention Fig. 3 is a block diagram of a method for guiding at least one vehicle according to the present invention.

[0051] Fig. Figure 1 shows a guidance device 1 according to one embodiment of the invention, which is designed as a hand-held module or front-end. Preferably, this device has at least one sensor 3, in particular an acceleration sensor, a position sensor, and / or a rotary wheel sensor. Using these sensors, a movement pattern of a person or an authorized person, in particular a police officer, a firefighter, a customs officer, a parking attendant, or a school crossing guard, etc., can be measured.

[0052] The signal baton or hand-held module 1 has a user interface 8, in the present embodiment a handle of the baton, with which the authorized person can interact with the baton. The movement patterns transmitted by the person to the hand-held module via the user interface are preferably transferred via measurements from the respective sensor(s) 3 into a coordinate system with the three spatial axes X, Y, Z and are preferably evaluated using algorithms. From this evaluation of the movement patterns, instructions are preferably derived which contain at least information about the movement pattern executed by the authorized person. The instruction preferably also contains the control command which is to be given to a vehicle A 2 or a driver assistance system of the vehicle and / or the driver of the vehicle.By means of a transmission module 4a, the instruction is preferably transmitted to at least one vehicle A2 and / or to a central computer 5. The transmission can be targeted to a single vehicle A2, as well as to vehicles 2 that meet certain criteria, e.g., vehicle type, size, weight, geographical location, etc.

[0053] In an alternative embodiment, the guidance device 1 can also be a portable computer, in particular a smartphone. Software, in particular an app, can preferably be installed on this computer, so that the functional elements according to the invention are present. In this case, the housing of the smartphone preferably serves as the user interface 8. The sensors 3 are preferably already present in the smartphone before the software is installed.

[0054] The hand-held module 1 preferably also has a second user interface 6, which preferably reports back to the authorized person executing the movement patterns that a movement pattern has been detected. If such feedback is not provided, the authorized person knows that the movement pattern has not been recognized. The second user interface 6 is designed in particular as a vibrator or as a visual display. In a further alternative embodiment, the guidance device is not designed as a hand-held module, but as an image sensor A for detecting a movement pattern of the authorized person. The image sensor A, in particular a camera, preferably records the movement of the authorized person, recognizes the authorized person and their movement in an environment, and uses algorithms to derive instructions to a vehicle A 2 from the recorded image or image sequence.

[0055] In all embodiments, the movement pattern, preferably after detecting and deriving an instruction, is automatically assigned to a classification of instructions, e.g., "Please stop" / "Wait for me," "School crossing guard wants to cross the street," etc. Based on this classification, a standardized signal is then preferably generated and transmitted via the transmission module to an approaching vehicle A. The transmission module can communicate with the vehicle A and / or the central computer using any communication protocol with which data packets can be transmitted, in particular via Car2X, Bluetooth, GSM, DSC (Digital Selective Call), UMTS, WLAN, LTE, and LTE D2D (Device-to-Device), etc.

[0056] The guidance device 1 is preferably charged via a USB cable or via induction, for example via a holder for fixing the trowel in an emergency vehicle, in which a corresponding device is preferably integrated.

[0057] Preferably, the respective guidance device comprises a distance module for determining the distance to a vehicle A, in particular a radar or a lidar. Further preferably, the guidance device comprises a direction module for determining the direction in which the guidance is being used, in particular a compass. These modules can be implemented both as hardware elements and as software elements.

[0058] Using the distance module and / or the direction module, the guidance device can determine which vehicle A2 should be addressed based on the person's movement patterns. The distance to a vehicle A2 can also be determined by a distance determination using a satellite navigation system, in which case the guidance device preferably has a position determination module. From the position of the guidance device 1 and the surrounding vehicles A2, it is then preferably possible to deduce which vehicle A2 should be addressed.

[0059] Further preferably, the guidance device 1 has an authentication module for identifying a person authorized to use the guidance device 1. The authentication module can preferably be embodied in hardware as a biometric sensor, which, for example, recognizes the fingerprint or the palm of the authorized person when they are in contact with the user interface 8. Further preferably, the authentication module can be embodied as a radio identification system or as an RFID identification system, each of which recognizes a transponder that the authorized person must carry. Furthermore preferably, the authentication module can also determine, instead of or in addition to authorizing a person, whether an emergency vehicle belonging to an authorized person is within a defined radius.In this case, the guidance device only operates if the person is within a radius of 100 m, more preferably within a radius of 70 m, even more preferably within a radius of 50 m, even more preferably within a radius of 30 m, and particularly preferably within a radius of 10 m. If the person is authorized to use the guidance device 1, the guidance device resumes normal operation. If this guidance device is not authorized, a notification can preferably also be sent to a person authorized to use the guidance device, which notification preferably states that an unauthorized person is using the guidance device 1.

[0060] The authentication of an authorized person can preferably be carried out as follows: An assignment of the signaling device to a person or emergency vehicle is preferably stored in a database, for example, similar to a weapon number. This assignment is preferably either permanently linked to an authorized person or is dynamically assigned at the start of the authorized person's shift. If radio or RFID authentication is selected as described above, the authorized person's work cell phone or a SIM card of an emergency vehicle can preferably serve as the authorizing transponder, which also preferably allows for use limited to a radius around an emergency vehicle.

[0061] The method according to the invention has the advantage that an instruction given by an authorized person using movement patterns or gestures is automatically and correctly recorded and can be transmitted to a vehicle A 2 to be directed, without changing established traffic processes, such as the directing of traffic by a police officer using a traffic baton. This also makes the new method compatible with previous traffic management practices, so that vehicles 2 with different technological levels of development, e.g., conventional vehicles 2 on the one hand and fully automated vehicles 2 on the other, can continue to participate in traffic together.

[0062] Furthermore, authentication to prevent misuse can also preferably be achieved by entering a number combination, a password, or even a regional restriction, e.g., use only in Bavaria, of the control device 1.

[0063] In Fig. 2 shows a guidance system according to the invention. This comprises at least the guidance device 1 presented above, which can preferably communicate with a vehicle A 2 via a wireless connection using the aforementioned communication protocols. For this purpose, a control unit is preferably present in the vehicle A 2. This control unit preferably has at least one receiving module that can receive the at least one instruction from the guidance device 1, an interpretation module that can interpret the at least one instruction, and a control module that can issue at least one control command to the at least one vehicle and / or the driver based on an interpretation of the instruction.

[0064] Furthermore, the control unit in the vehicle A 2 preferably further comprises a transmission module in order to report a successful transmission of an instruction to the vehicle A 2 back to the control device 1.

[0065] In a preferred embodiment, the control unit further comprises a third user interface which can transmit the control command to the driver. This third user interface can be, for example, a screen or a display on which the respective control commands are visually presented to the driver. Preferably, the control commands can be presented directly on a chart plotter or in a navigation system present in the vehicle A 2. As an alternative or further user interface, a loudspeaker can preferably be provided via which the control command can be reproduced acoustically. Preferably, loudspeakers already present in the vehicle A 2 are used here too. Finally, the control command can also be transmitted to the driver via other sensory organs of the driver, e.g. tactilely via the driver's seat or the steering wheel.

[0066] In a preferred embodiment, the guidance system additionally has an image sensor B 7, which is designed in particular as a camera. This image sensor B 7 can preferably be arranged in the emergency vehicle or be designed as a stationary part of the road infrastructure. More preferably, it is a mobile camera that can be set up at the side of the road. The image sensor B 7 also preferably has a transmission module 4 b, via which the image sensor B 7 can transmit information to the guidance device 1. With this image sensor B 7, which can also be designed as part of a hand-held module as a guidance device 1, the license plate number of an approaching vehicle A 2 to be guided and / or other identifying features of the vehicle A 2 can preferably be automatically recognized.If the vehicle is identified in this way, an instruction can be addressed to this vehicle A 2 in this way and transmitted using the aforementioned transmission methods, e.g. multicast.

[0067] In a further preferred embodiment, the control system has a central computer 5, which also has a receiving and transmitting module and an antenna 9. In this embodiment, the control device 1 and the vehicle A 2 preferably communicate via the central computer 5. Further preferably, this central computer 5 is designed as a backend in which data, in particular the data collected by the control device 1 and the vehicle A 2, are stored. The control device 1 and the vehicle A 2 can then each access this data on the central computer 5. This has the particular advantage that data from the control device 1 can be retrieved on the central computer 5 for several vehicles A 2, even if they have no communication connection to the control device 1 itself.

[0068] In a preferred embodiment, the vehicle A 2 is a partially, highly, or fully automated vehicle. Instructions or resulting control commands are preferably only issued to the driver of a vehicle A if the driver is to intervene in the driving behavior of the vehicle A 2 or change the operating strategy of the vehicle A 2. A change in the operating strategy can, for example, be switching from a fully automated driving mode to a partially automated driving mode or even to manual driving mode. If driver intervention is not required or the driver does not need to be made aware of a certain traffic situation, the control commands are preferably issued directly to the vehicle A 2, in particular to a driver assistance system of the vehicle A 2, which controls the lateral and / or longitudinal guidance of the vehicle A 2.

[0069] Based on the Fig. 3, an application example for a guidance device 1 according to the invention or a guidance system according to the invention is presented below. A police officer wishes to conduct a police check in flowing traffic at a parking lot. To do so, he uses a guidance device 1 according to the invention in the form of a handheld module, in particular a traffic light. He preferably removes this from a specially provided holder in his emergency vehicle, in which a battery of the traffic light can be charged via induction. First, the police officer must authenticate himself, preferably as an authorized user, on the traffic light. For this purpose, a fingerprint scanner, which automatically identifies the police officer 101, is preferably located on the handle of the traffic light 1, which is designed as a user interface 8.This authentication process 101 is preferably repeated when the police officer puts the signal baton 1 down or does not move it for a longer period of time.

[0070] Furthermore, the signal baton 1 preferably checks whether it is located at a defined distance from the police officer's emergency vehicle 102. This check 102 also serves to prevent unauthorized use of the signal baton 1. In the present case, the police officer's emergency vehicle is also located in the parking lot within a radius of less than 100 m from the signal baton 1, so that the signal baton 1 authorizes its use. To prevent further unauthorized sending of instructions to vehicles A 2, the signal baton 1 preferably also has a "Trusted Computing Platform" module that signs each instruction using digital certificates. On the side of the vehicles A 2 to be controlled, the signature of each instruction is verified, and only correctly signed instructions are followed by an action by one or more vehicles A 2.

[0071] The guidance device 1 can also be integrated into the clothing of an authorized person or, for example, into other devices present in an emergency vehicle, such as a delusion triangle.

[0072] The police officer now preferably carries out movement patterns or gestures in order to pull individual vehicles A out of traffic. In doing so, the guidance device 1 preferably detects these movement patterns 103. From these movement patterns, the guidance device derives an instruction to at least one vehicle A 2 104. The vehicle A 2 is preferably detected, as described above, by the guidance device 1 via the spatial proximity and / or the orientation of the baton 1 in relation to the vehicle A 2, the orientation of the police officer's movement pattern, the spatial proximity of the guidance device 1 or to the police officer to an emergency vehicle, by an input from the police officer, e.g. by a voice input, and / or by an image sensor B, which is installed on the signal baton 1 or on the police officer's emergency vehicle or is set up as a mobile camera 7 at the side of the road.Furthermore, an instruction can also be directed to all vehicles A2 that are within a certain distance from the police officer, guidance device, or emergency vehicle. Based on the distance, the specific vehicle(s) A2 to which an instruction should be sent can be determined. 105

[0073] In a further step, the instruction is preferably transmitted 106 to the at least one vehicle A 2 to be guided. Alternatively or additionally, the instruction can also be transmitted to a central computer 5, via which the guidance device 1 can communicate 106 with the at least one vehicle A 2 to be guided.

[0074] A definition of the area in which vehicle A2 is to be guided can contain geodata of the area, a latitude-longitude radius or even a geographical shape, e.g. a parking lot in which vehicle A2 is to be guided.

[0075] In a further step, preferably a control unit or an interpretation module of a control unit of the vehicle A 2 interprets the instruction and derives control commands from it to the vehicle A 2 or its driver assistance system 107. Alternatively, control commands can also be derived directly, preferably to the driver of the vehicle A 2. These control commands are output to the vehicle A or its driver assistance system or to the driver 108. If the output is to the driver assistance system, this occurs via a protocol for communication between the control unit and the driver assistance system.

[0076] If the output is given to the driver, this is preferably done visually, acoustically or tactilely.

[0077] Preferably, the successful transmission of an instruction and / or the successful derivation of a control command from the instruction is reported back 109 to the police officer or via the guidance device 1 or the signal baton. This feedback is preferably reported back to the police officer via the user interface 8, in this case the handle of the signal baton 1. Furthermore, this feedback can also be provided to the police officer acoustically or visually. As further information for identifying a vehicle A2, the instruction could contain information about the vehicle weight, the vehicle type, and / or the direction of travel, so that a vehicle addressed can identify itself as the vehicle A2 to be guided.If the above-described process has been successful, the vehicle A 2 to be directed will stop automatically in the parking lot so that the police officer can carry out an inspection, or the vehicle A 2 will hand over control to the driver so that the driver can maneuver the vehicle A 2 in the parking lot.

[0078] Of course, it will be apparent to the person skilled in the art that the working steps of the method according to the invention can also be carried out in a different Fig. 3 can be executed in the order specified.
