Patent Description:
Vehicular communication is a field of research and development. To enable autonomous or semi-autonomous driving of vehicles, such vehicles can (inter alia) use information on their environment from communication via, e.g., dedicated short-range communication (DSRC) with other vehicles or fixed installed transmitter in the environment of the vehicle. To handle so-called "deadlock situations", autonomous or semi-autonomous driving of vehicles can be controlled using tele-operated driving (ToD). The main concept of ToD is that an automated vehicle (AV) is remotely driven by a remote control/command center (CC). CC and AV may be far away from each other.

Document <CIT> describes a concept for vehicular communication. The concept comprises sensing a condition associated with the autonomous vehicle, and initiating, by a controller in response to the sensing of the condition, communication pertaining to the autonomous vehicle between a vehicle manager remote to the autonomous vehicle and an external agent external to the autonomous vehicle. The autonomous vehicle communication method further comprises controlling the autonomous vehicle remotely in response to a command that is based on the condition associated with the autonomous vehicle and the communication between the vehicle manager and the external agent.

Document <CIT> discloses a concept which enables an autonomous vehicle to request assistance from a remote operator in certain predetermined situations. The concept provides for determining a representation of an environment of an autonomous vehicle based on sensor data of the environment and identifying based on the representation a situation from a predetermined set of situations for which the autonomous vehicle will request remote assistance. The concept further includes sending a request for assistance to a remote assistor, the request including the representation of the environment and the identified situation. The method may additionally include receiving a response from the remote assistor indicating an autonomous operation. The method may also include causing the autonomous vehicle to perform the autonomous operation.

<CIT> reveals a method for a vehicle to determine a route section comprising operating the vehicle in an automated driving mode and determining an exceptional traffic situation. The method further comprises transmitting information related to the exceptional traffic situation to a network component using a mobile communication system and receiving information related to driving instructions for the route section to overcome the exceptional traffic situation from the network component, wherein the receiving of the driving instructions comprises tele-operating the vehicle along the route section to overcome the exceptional traffic situation. Document D1 does not reveal receiving message comprising information on the environment directly form a traffic entity.

<CIT> reveals a method in a Wireless device comprising detecting, at a first time period, a first status of an object based on dynamic properties of the object and communicating the first status of the object to a network element. Further, the method comprises predicting, at a second time period after the first time period, a status of the object based on the first status of the object and detecting, at the second time period, a second status of the object based on dynamic properties of the object. Further, the method comprises upon determining that the predicted status is different than the second status, communicating the second status to the network element.

<CIT> reveals a method at a network element for collective perception in an intelligent transportation system. The method includes receiving from each of a plurality of intelligent transportation system stations, a local dynamic map and creating, based on the local dynamic map from each of the plurality of intelligent transportation system stations, a local collective perception map. Further, the method comprises distributing the local collective perception map to at least one of the plurality of intelligent transportation system stations.

The prior art concepts describe a concept for sharing information about the environment of a remotely controllable vehicle with a tele-operation driver within a common mobile network. However, the prior art concepts do not share the full information available at the vehicles.

Hence, there is a demand for an improved concept for communicating in a tele-operated driving session.

This demand may be satisfied by the subject-matter of the appended independent and dependent claims.

Embodiments are based on the finding that a vehicle can be used for relaying information from a message (e.g. a cooperative awareness message (CAM), decentralized environmental notification message (DENM), signal phase and timing (SPaT), and/or a collective perception message (CPM)), which is locally available for the vehicle, to a remote control center to benefit from the information, e.g., when controlling the vehicle from remote. Hence, the CC is enabled to receive messages or information comprised in these messages (e.g. CAM, DENM, CPM, SPaT) which are merely locally available (i.e. receivable) for the AV. Therefore, the CC may be enabled to use information from such messages for the tele-operated driving. Embodiments may enable the tele-operation driver of a vehicle to receive and use information locally available to the vehicle.

Embodiments provide a method for a vehicle and for communicating in a tele-operated driving session between the vehicle and a remote control center. The method comprises establishing the tele-operated driving session. The method further comprises receiving, by the vehicle, a message including information on the environment of the vehicle from a traffic entity outside the vehicle. Further, the method comprises transmitting, by the vehicle, the information to the remote control center for controlling the vehicle from remote based on the information. In other words, the method provides for forwarding the information from the message to the remote control center. In this way, the information from the message can be provided to the remote control center even if the remote control center is not recipient of the message from the traffic entity, e.g., if the remote control center is not able to receive the message or the remote control center is outside a transmission range of the traffic entity. In particular, the above method enables the remote control center to analyze, process, and/or use the information for controlling the vehicle from remote. This may improve the control/operation of the vehicle by the remote control center.

The method comprises receiving the message directly from the traffic entity. The traffic entity, for example, is another vehicle or an infrastructure component configured to transmit the message. The vehicle, e.g., receives the message directly via direct communication, e.g., device-to-device (D2D), vehicle-to-vehicle (V2V), car-to-car communication (C2C), vehicle-to-infrastructure (V2I), or vehicle-to-anything (V2X) communication. The direct communication can enable transmitting the message with lower latencies than other communication technologies.

In some embodiments, the method comprises receiving the message from the traffic entity via dedicated short-range communication, DSRC, and/or via geocast communication. Thus, the messages are transmitted in a predefined transmission range/reception area and (only) locally receivable/available for recipients within the predefined transmission range/reception area. Geocast communication and DSRC may exhibit a higher integrity/lower risk of manipulation and lower latentcies than cellular communication technologies.

In some embodiments, the method comprises transmitting the information via a cellular network to the remote control center. In this way, the vehicle can transmit the information over larger distances to the remote control center than, e.g., using short-range communication technologies.

In some embodiments, the message includes at least one of a cooperative awareness message, CAM, a decentralized environmental notification message, DENM, a collective perception message, CPM, and a signal phase and timing, SPaT. Accordingly, the information may include information from the CAM, DENM, CPM, and/or the SPaT. Thus, the method can enable the remote control center to receive information from the CAM, DENM, CPM, and/or the SPaT and to use such information for controlling the vehicle from remote, i.e. tele-operation of the vehicle.

In some embodiments, the method comprises receiving a first message including first information on the environment of the vehicle from a first traffic entity outside the vehicle. The method can further comprise receiving at least one second message including second information on the environment of the vehicle from a second traffic entity outside the vehicle. Further, the method can comprise collecting the first and the second information in a data container. Additionally, the method can comprise transmitting the data container to the remote control center. In this way, the information from multiple messages can be provided to the remote control center. Consequently, an amount of information available for the remote control center for controlling the vehicle from remote may be increased.

In particular, collecting the first information and the second information in the data container may comprise removing redundant information from the first and/or second information. This allows, e.g., to remove redundancies between the first and the second information and, thus, reduce a data size of the information to be transmitted to the remote control center. The first information, e.g., comprise inter alia redundant (e.g. partly corresponding to the second information) information on a position of another vehicle. The method, e.g., provides for removing such redundant information from the first and/or second information before transmitting the first and the second information in the data container to the remote control center.

Other embodiments provide a method for a remote control center and for communicating in a tele-operated driving session between the vehicle and a remote control center. The method comprises receiving, by the remote control center, information on the environment of the vehicle from a traffic entity indirectly via the vehicle. The method further comprises controlling the vehicle based on the information. This, e.g., enables the remote control center to receive information which might (only) be available/receivable locally for the vehicle and an improved tele-operation of the vehicle.

In some embodiments, the method comprises processing the information into a human readable presentation of the information at the remote control center for controlling the vehicle based on the human readable presentation of the information. Thus, a human tele-operating driver controlling the vehicle via the remote control center can perceive the information.

Other embodiments provide a communication circuit for a vehicle. The communication circuit comprises one or more interfaces configured to communicate in a communication network. The communication circuit further comprises a data processing circuit configured to control the one or more interfaces, wherein the data processing circuit is further configured to execute one of the methods for a vehicle which are described herein. Other embodiments provide a vehicle comprising an embodiment of such a communication circuit.

Other embodiments provide a communication circuit for a vehicle. The communication circuit comprises one or more interfaces configured to communicate in a communication network. The communication circuit further comprises a data processing circuit configured to control the one or more interfaces, wherein the data processing circuit is further configured to execute one of the methods for a remote control center which are described herein. Other embodiments provide a vehicle comprising an embodiment of such a communication circuit.

Embodiments further provide a computer program having a program code for performing one or more of the above described methods, when the computer program is executed on a computer, processor, or programmable hardware component. A further embodiment is a computer readable storage medium storing instructions which, when executed by a computer, processor, or programmable hardware component, cause the computer to implement one of the methods described herein.

Teleoperated Driving (ToD) is becoming a key enabler for automated driving. ToD may help to solve deadlock situations which cannot be solved by an automated driving vehicle itself. ToD may also become a legal requirement for automated driving in an increasing number of countries.

Dedicated short-range communications (DSRC) has been designed to support intelligent transportation systems (ITSs). The rationale behind DSRC is that messages emitted via DSRC are only locally receivable, e.g., for the vehicle. In ToD applications, a remote control center for controlling the vehicle from remote may not be able to receive the messages via DSRC. Thus, the remote control center may not be able to profit from such messages emitted via DSRC.

Moreover, information included in the messages may be exhibit a machine readable representation. Thus, a human tele-operating driver controlling the remote control center may not be able to read/perceive the information.

This demand may be satisfied by the embodiments described below.

<FIG> illustrates a block diagram of an embodiment of a method <NUM> for a vehicle and for communicating in a tele-operated driving session between the vehicle and a remote control center. Method <NUM> comprises establishing <NUM> the tele-operated driving session. The vehicle can be an autonomous or semi-autonomous driving of vehicle. In so-called "deadlock situations", in which the vehicle cannot maneuver automatically/autonomously in a safe way, the vehicle may initiate the tele-operated driving session between the vehicle and the remote control center. Establishing <NUM> the tele-operated driving session, e.g., includes establishing a data connection or communication path to the remote control center. Optionally, establishing <NUM> the tele-operated driving further comprises sending a request to take control over the vehicle by the remote control center and/or transmitting sensor data of the environment to the remote control center.

The tele-operated driving session can be understood as a part or the entirety of acts for controlling the vehicle from remote and for communicating between the vehicle and the remote control center.

Method <NUM> further comprises receiving <NUM>, by the vehicle, a message including information on the environment of the vehicle from a traffic entity outside the vehicle. The vehicle, e.g., receives the message wirelessly via a radio signal emitted by the traffic entity. A skilled person having benefit from the present disclosure will appreciate that the vehicle may comprise suitable technical means for (wirelessly) receiving <NUM> the message. The traffic entity, e.g., is another vehicle or a stationary transmitter (e.g. a infrastructure component for wirelessly emitting the message). The message, e.g., comprises or corresponds to a cooperative awareness message (CAM), a decentralized environmental notification message (DENM), a collective perception message (CPM) or signal phase and timing (SPaT), i.e. a message indicative of SPaT.

The CAM, e.g., includes inter alia information on a position and a velocity of another vehicle in the environment of the vehicle. The CPM, e.g., includes inter alia one or more trajectories of another vehicle in the environment of the vehicle. The DENM can particularly contain a history of the last sent information. SPaT, e.g., is indicative of a state and timing of traffic lights. For example, the SPaT indicates when a traffic light is turned green, yellow, and/or red and/or when a traffic light changes between green, yellow, and/or red.

The traffic entity may have a predefined transmission range or area where the message is emitted. Therefore, the message may be receivable only in the predefined area or transmission range.

It is noted that the information on the environment can comprise a part or the entire message, e.g. a part or the entire content of the message. The information can be indicative of data, e.g., a position, a direction of movement, an acceleration, a velocity, a trajectory of one or more other vehicles in the environment. The information can alternatively or additionally comprise any kind of other ("high-level") information on the traffic (e.g. legal traffic regulations, a (road) map of the environment) and/or on the situation (e.g. weather or road conditions) in the environment of the vehicle.

In addition to the information, the vehicle may also transmit sensor data from one or more on-board sensors (e.g. one or more LIDAR sensors, cameras, time-of-flight (TOF) cameras, radar sensors, ultra sonic sensors, thermal imaging cameras, rain sensors, global positioning system interfaces, and/or motion sensors) to the remote control center.

Method <NUM> further comprises transmitting <NUM>, by the vehicle, the information to the remote control center for controlling the vehicle from remote based on the information. The vehicle, e.g., selects/extracts the information from the message before transmitting the information to the remote control center. For this reason, the vehicle may be equipped with a data processing circuit configured to select/extract the information from the message. The vehicle can emit/transmit the information wirelessly via a radio signal. In particular, the vehicle can transmit the information out of the above transmission range or area of the traffic entity, e.g., to provide the information to the remote control center if the remote control center is located outside this area or transmission range. A skilled person having benefit from the present disclosure will appreciate that the vehicle may comprise suitable technical means for (wirelessly) transmitting <NUM> the information. The information, e.g., is transmitted via a cellular network to the remote control center. For example, the vehicle uses cellular network communication technologies (e.g. second-, third-, fourth-, or fifth-generation (<NUM>, <NUM>, <NUM>, or <NUM>) network technologies).

Method <NUM> may enable the remote control center to receive information from the message even if the remote control center is not able to receive the message (directly) from the traffic entity, e.g., if the remote control center is outside, i.e. not within or adjacent to, a transmission range of the traffic entity or a reception area of the message.

The skilled person having benefit from the present disclosure will appreciate that method <NUM> also allows to provide information from multiple received messages to the remote control center.

Method <NUM>, e.g., comprises receiving a first message including first information on the environment of the vehicle from a first traffic entity outside the vehicle and receiving at least one second message including second information on the environment of the vehicle from a second traffic entity outside the vehicle.

It is noted that the above explanations in connection with the message, the information, and the traffic entity may also apply to the first and the second traffic entity, the first and the second information, and/or the first and the second message, respectively.

Each of the messages (the first and the second message) may comprise or correspond to a cooperative awareness message (CAM), a decentralized environmental notification message (DENM), a collective perception message (CPM) or signal phase and timing (SPaT), i.e. a message indicative of SPaT.

The first and the second traffic entity may be different traffic entities or the same traffic entity. For example, the first and the second traffic entity correspond to different other vehicles or the same other vehicle in the environment of the vehicle. It is understood that the first and the second message can be received simultaneously or consecutively, i.e. one after the other. It is further understood that the method can also comprise receiving more than two messages.

The method <NUM> may further comprise collecting the first and the second information in a data container. The data container can be understood as a network packet, e.g., including data indicative of the first and the second information.

Method <NUM> may further comprise transmitting the data container to the remote control center. The data container can be transmitted in equivalent manner, e.g. using the same technology, as explained above in connection with the information.

This allows to provide the information from multiple messages to the remote control center. Thus, an amount of information available to the remote control center may be increased. The remote control center may benefit from the increased amount of information when controlling the vehicle from remote.

The method may further comprise removing redundancies (e.g. redundant/similar information) from the first and/or the second information. For example, similar information on the same other vehicle in the environment of the vehicle can be removed from the first or the second information. The redundancies, e.g., are removed while collecting the first and the second information in the data container. This can reduce a load on a communication path between the vehicle and the remote control center when transmitting the data container to the remote control center. This may further increase a spectral efficiency of the communication between the remote control center and the vehicle.

Method <NUM> can be executed iteratively. If method <NUM> is executed iteratively, multiple data containers including respective information can be transmitted consecutively. More particularly, the data containers may be transmitted periodically.

Method <NUM> can be performed by a communication circuit as described below.

<FIG> illustrates a block diagram of an embodiment of a communication circuit <NUM> for a vehicle <NUM>.

The communication circuit <NUM> comprises one or more interfaces <NUM> configured to communicate in a communication network and a data processing circuit <NUM> configured to control the one or more interfaces <NUM>. The data processing circuit <NUM> is configured to execute the above method for a vehicle.

In embodiments, the one or more interfaces <NUM> may correspond to any means for obtaining, receiving, transmitting or providing analog or digital signals or information, e.g. any connector, contact, pin, register, input port, output port, conductor, lane, etc. which allows providing or obtaining a signal or information. An interface may be wireless or wireline and it may be configured to communicate, i.e. transmit or receive signals, information with further internal or external components. The one or more interfaces <NUM> may comprise further components to enable according communication in the (mobile) communication system, such components may include transceiver (transmitter and/or receiver) components, such as one or more Low-Noise Amplifiers (LNAs), one or more Power-Amplifiers (PAs), one or more duplexers, one or more diplexers, one or more filters or filter circuitry, one or more converters, one or more mixers, accordingly adapted radio frequency components, etc. The one or more interfaces <NUM> may be coupled to one or more antennas, which may correspond to any transmit and/or receive antennas, such as horn antennas, dipole antennas, patch antennas, sector antennas etc. In some examples the one or more interfaces <NUM> may serve the purpose of transmitting or receiving or both, transmitting and receiving, information, such as information, input data, control information, further information messages, etc..

As shown in <FIG> the respective one or more interfaces <NUM> are coupled to the respective data processing circuit <NUM> at the communication circuit <NUM>. In embodiments the communication circuit <NUM> may be implemented using one or more processing units, one or more processing devices, any means for processing, such as a processor, a computer or a programmable hardware component being operable with accordingly adapted software. In other words, the described functions of the data processing circuit <NUM> may as well be implemented in software, which is then executed on one or more programmable hardware components. Such hardware components may comprise a general-purpose processor, a Digital Signal Processor (DSP), a micro-controller, etc..

In particular, the one or more interfaces <NUM> can comprise at least one interface for wirelessly receiving the message embedded in a radio signal emitted by the traffic entity. More particular, the traffic entity may emit the radio signal within a limited range. In other words, the radio signal may have a limited range. The traffic entity, e.g., uses communication technology with limited range for the radio signal, thereby providing the message (only) to recipients within the range of the radio signal. Accordingly, the interfaces <NUM> may comprise at least one respective interface for receiving the message via such radio signals. The traffic entity, e.g., uses DSRC and/or geocast communication (technology). Accordingly, the one or more interfaces <NUM>, e.g., comprise at least one DSRC communication interface and/or at least one geocast communication interface for receiving the message/the signal via DSRC and/or geocast communication, respectively. It is noted that additionally or alternatively other interfaces may be used to receive the message.

The data processing circuit <NUM> may be configured to receive the message, e.g. via the radio signal, over the one or more interfaces <NUM>. The data processing circuit <NUM> can extract the message from the received radio signal, e.g., through signal processing. The data processing circuit <NUM> may be further configured to extract the information from the message, e.g., through data processing. Optionally such data processing comprises decrypting the message and/or a content of the message. As described above, the information may be the entire or a part of the message or its content.

At least one of the one or more interfaces <NUM> is configured to communicate with the remote control center to transmit the information to the remote control center. In particular, the interfaces <NUM> comprise at least one interface configured to transmit the information to the remote control center via a wireless network, e.g. a cellular network, e.g., using <NUM>, <NUM>, <NUM>, and/or <NUM> network technology. The data processing circuit <NUM> may be configured to generate a communication signal bearing the information. Further, the data processing circuit <NUM> may be configured to transmit the information to the remote control center. For example, the data processing circuit <NUM> may use one or more of the above interfaces <NUM> for transmitting the information via the communication signal.

In some embodiments, the data processing circuit <NUM> may reroute the message to the remote control center through cellular communications. Hence, the data processing circuit <NUM> can be understood as message routing module (MRM).

It is noted that the communication circuit <NUM> may be used for applications in vehicles, but also in communication applications for, e.g., robots or communication devices.

Vehicle <NUM>, e.g., is an automated vehicle (i.e. semi-autonomously or autonomously driving vehicle). The above communication circuit <NUM> particularly enables the vehicle <NUM> to communicate information from messages which are locally receivable for the vehicle <NUM> with the remote control center. More particularly, the communication circuit <NUM> (and the corresponding method <NUM>) may provide a human or automatic tele-operating driver controlling the vehicle <NUM> from remote with the information from the message, and thus, with an increased amount of information. This may improve the control of the vehicle <NUM> from remote in teleoperated driving sessions. For example, the remote control center, the human, and or the automatic tele-operating driver can maneuver the vehicle <NUM> more safely with respect to the information, e.g., the velocities, trajectories, and/or positions of vehicles, and/or the timing of the traffic lights in the environment of the vehicle <NUM>, as laid out in more detail later.

<FIG> illustrates a block diagram of an embodiment of a method <NUM> for a remote control center and for communicating in a tele-operated driving session between a vehicle and a remote control center.

Method <NUM> comprises receiving <NUM>, by the remote control center, information on the environment of the vehicle from a traffic entity indirectly via the vehicle. As described above, the information may be extracted from a message locally available/receivable for the vehicle and forwarded by the vehicle to the remote control center. In particular, may comprise receiving the information via a communication path between the remote control center and the vehicle over a cellular network. The communication path may be the same communication path which is used for the communication of control commands for controlling the vehicle from remote. The skilled person having benefit from the present disclosure will appreciate that optionally other communication paths may be used, e.g., using other communication technology.

Method <NUM> further comprises controlling <NUM> the vehicle using the information. For example, a human and/or an automatic tele-operating driver controlling the vehicle may use the information as input for controlling the vehicle.

It is noted that explanations to features of method <NUM> may also apply to respective features of method <NUM>. In some applications, method <NUM> is implemented in combination with method <NUM>.

Method <NUM> may further comprise processing the information into a human readable presentation of the information at the remote control center for controlling the vehicle based on the human readable presentation of the information. The information, e.g., is encrypted and/or encoded such that a human may not be able to read/perceive the information. Method <NUM>, e.g., comprises decrypting and/or decoding such information and processing the information into a visual representation of the information. The processing may also include reconstructing and displaying objects within the environment in a 3D scene, velocity vectors, and emergency messages. For example, method <NUM> comprises displaying positions, dimensions, velocities and/or trajectories of other vehicles and/or a timing and/or a state of traffic lights in the environment of the vehicle for a human tele-operating driver controlling the vehicle. The information, e.g., is displayed on a screen or display.

<FIG> illustrates a block diagram of an embodiment of a communication circuit <NUM> for a remote control center <NUM> for remotely controlling a vehicle.

The communication circuit <NUM> comprises one or more interfaces <NUM> configured to communicate in a communication network. The communication circuit <NUM> further comprises a data processing circuit <NUM> configured to control the one or more interfaces <NUM>. The data processing circuit <NUM> is configured to execute method <NUM>.

In embodiments the one or more interfaces <NUM> may correspond to any means for obtaining, receiving, transmitting or providing analog or digital signals or information, e.g. any connector, contact, pin, register, input port, output port, conductor, lane, etc. which allows providing or obtaining a signal or information. An interface may be wireless or wireline and it may be configured to communicate, i.e. transmit or receive signals, information with further internal or external components. The one or more interfaces <NUM> may comprise further components to enable according communication in the (mobile) communication system, such components may include transceiver (transmitter and/or receiver) components, such as one or more Low-Noise Amplifiers (LNAs), one or more Power-Amplifiers (PAs), one or more duplexers, one or more diplexers, one or more filters or filter circuitry, one or more converters, one or more mixers, accordingly adapted radio frequency components, etc. The one or more interfaces <NUM> may be coupled to one or more antennas, which may correspond to any transmit and/or receive antennas, such as horn antennas, dipole antennas, patch antennas, sector antennas etc. In some examples the one or more interfaces <NUM> may serve the purpose of transmitting or receiving or both, transmitting and receiving, information, such as information, input data, control information, further information messages, etc..

In particular, the one or more interfaces <NUM> may comprise at least one interface for communicating with the vehicle over a wireless, e.g. a cellular, network. The interfaces <NUM>, e.g., comprise a cellular network interface, e.g. for access to a <NUM> network or a wireless local area network. Thus, the data processing circuit <NUM> can receive the information via the wireless network using one or more of the interfaces <NUM>.

The data processing circuit <NUM> may be also configured to process the information into a human readable, e.g., a visual/graphic, representation.

The remote control center <NUM> may further comprise one or more screens for displaying the information (in a human readable representation), e.g., to a human tele-operating driver of the vehicle.

An exemplary application of the above methods and communication circuits is described below with reference to <FIG>.

<FIG> schematically illustrates the communication of a vehicle <NUM>. Vehicle <NUM>, e.g. is an automated vehicle equipped with an embodiment of the communication circuit (i.e. the communication circuit for a vehicle) described herein for communicating with another vehicle <NUM> and a traffic light <NUM> in the environment of the vehicle <NUM>.

Vehicle <NUM> is equipped with a DSRC transmitter for emitting a CAM <NUM>. The traffic light <NUM>, e.g., is equipped with another DSRC transmitter for emitting a SPaT (message) <NUM>. As usual for DSRC, the CAM <NUM> and the SPaT <NUM> is (only) receivable in a predefined area <NUM>, e.g., within a radius of a few <NUM>. The predefined area <NUM>, e.g., is indicative of a transmission range of the DSRC transmitters. Vehicle <NUM> may use the CAM <NUM> and the SPaT <NUM> as input for maneuvering autonomously within the environment.

In an exemplary scenario, the vehicle <NUM> gets into a deadlock situation. In order to handle the deadlock situation, the vehicle <NUM> can establish a tele-operated driving session with a remote control center <NUM> for controlling the vehicle <NUM>.

The remote control center <NUM> is located outside the area <NUM>. Hence, the remote control center <NUM> cannot receive the CAM <NUM> and/or the SPaT <NUM> from the traffic light <NUM> and/or the other vehicle <NUM> via DSRC.

Vehicle <NUM> can process the CAM <NUM> and the SPaT <NUM> to extract respective information <NUM> and <NUM> from the CAM <NUM> and the SPaT <NUM>, respectively. Further, the vehicle <NUM> may transmit the information <NUM> and <NUM> to the remote control center <NUM>. As described above, the vehicle <NUM>, e.g., transmits the information <NUM> and <NUM> via a wireless network (e.g. a cellular network) out of the area <NUM> to the remote control center <NUM>. Optionally, the vehicle <NUM> can bundle the information <NUM> and <NUM> in a data container/network packet and transmit the information <NUM> and <NUM> in the data container to the remote control center <NUM>. Further optionally, the vehicle <NUM> can directly forward the CAM <NUM> and/or the SPaT <NUM> to the remote control center <NUM>.

Also, the vehicle <NUM> may transmit sensor data (e.g. time-of-flight (TOF) data, radar data, LIDAR data, camera images) of one or more on-board sensors (e.g. camera(s), TOF camera(s), LIDAR sensor(s), radar sensor(s)) to the remote control center <NUM>.

This allows the remote control center <NUM> to analyze the environment using the sensor data, the information <NUM> and/or <NUM> and provide the vehicle <NUM> based on the sensor data and/or the information <NUM> and/or <NUM> with one or more control commands <NUM> for controlling the vehicle <NUM>. The control commands <NUM> are optionally transmitted via the same wireless and/or cellular network as the information <NUM>, <NUM>. Alternatively, those are transmitted via a separate network or communication path.

It is noted that the above example may also apply to the communication of information from CPM, DENM, etc..

It is noted that tele-operated driving may be also used in situations other than deadlock situations. Thus, the explanations herein in connection with tele-operated driving in deadlock situations also applies to tele-operated driving in other situations.

Claim 1:
A method (<NUM>) for a vehicle and for communicating in a tele-operated driving session between the vehicle and a remote control center, the method (<NUM>) comprising:
establishing (<NUM>) the tele-operated driving session;
receiving (<NUM>), by the vehicle, a signal phase and timing message including information on the environment of the vehicle directly from a traffic entity outside the vehicle, wherein the traffic entity is a stationary infrastructure; and
