[0001] This application claims the benefit of priority to U.S. Provisional Patent Application No. 63/158,966, filed March 10, 2021, entitled “Methods And Systems For Communication Vehicle-To-Everything (V2X) Information” and the entire contents thereof are hereby incorporated by reference for all purposes.

[0002] Many regions of the world are developing standards for vehicle-based communication systems and functions. There are standards developed by the Institute of Electrical and Electronics Engineers (IEEE) and the Society of Automotive Engineers (SAE) for use in North America, or the European Telecommunications Standards Institute (ETSI) and the European Committee for Standardization (CEN) for use in Europe. . The IEEE 802.11p standard is the basis for the Dedicated Short Range Communication (DSRC) and ITS-G5 communication standards. IEEE 1609 is a higher layer standard based on IEEE 802.11p. The Cellular Vehicle-to-Everything (C-V2X) standard is a competing standard developed under the auspices of the 3rd Generation Partnership Project. These standards serve as the foundation for vehicle-based wireless communications and can be used to support intelligent highways, autonomous and semi-autonomous vehicles, and improve the overall efficiency and safety of highway transportation systems. Other V2X wireless technologies are also being considered in various regions of the world. The techniques described herein are applicable to all V2X wireless technologies.

[0003] The C-V2X protocol defines two transmission modes that together provide 360° non-line-of-sight awareness and a higher level of predictability for improved road safety and autonomous driving. The first transmission mode includes vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), and a dedicated Intelligent Transportation System (ITS) 5.9 gigahertz independent of cellular networks. Includes direct C-V2X, providing improved communication range and reliability in the (GHz) spectrum. The second transmission mode is third generation wireless mobile communications technologies (3G) (e.g., global system for mobile communications (GSM) evolved (EDGE) systems, code division multiple access (CDMA) 2000 systems, etc.), fourth generation Wireless mobile communication technologies (4G) (e.g., long term evolution (LTE) systems, LTE-Advanced systems, mobile Worldwide Interoperability for Microwave Access (WiMAX) systems, etc.), 5th generation new radio wireless mobile communication Technologies include vehicle-to-network communications (V2N) in mobile broadband systems and technologies such as 5G NR systems, etc.

[0004] An element of a V2X system is the ability for vehicles to broadcast a Basic Safety Message (BSM) in North America or a Cooperative Awareness Message (CAM) in Europe, which other vehicles can receive and process to improve traffic safety.

[0023] Various embodiments will be described in detail with reference to the attached drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to identical or similar parts. References made to specific examples and implementations are for illustrative purposes and are not intended to limit the scope of the claims.

[0024] V2X processing and communication systems can be implemented in a variety of vehicles, such as cars, trucks, buses, trailers, autonomous vehicles, robotic systems, etc. Additionally, an ITS or other V2X system includes multiple fixed equipment facilities such as RSUs, access nodes, and wireless relay nodes. Various embodiments may be implemented in any of a variety of V2X-equipped vehicles, fixed installations, and other devices using a V2X communications infrastructure. Additionally, various embodiments may be useful in systems that utilize V2X capabilities but are not related to ITS functionality, such as pay-to-park garages, wireless payment systems for various commercial applications, emergency medical services, etc. there is. To encompass all implementations of the various embodiments, the term “V2X node” is used throughout this description and claims to generally refer to a mobile, semi-mobile, or fixed system that implements V2X communication functionality. A non-limiting example of a V2X endpoint node used for illustration purposes is a vehicle, such as a car, that pays tolls while traveling on a toll road, but references to this and other examples are not intended to limit the scope of the claims reciting V2X nodes. That's not the intention.

[0025] A V2X node (eg, vehicle) may transmit various V2X messages related to different services. For example, a V2X node may include information about the V2X node, such as the identifier of the V2X node and the V2X node's location, speed, route, nearby road conditions, nearby vehicles, observed road conditions, and vehicle behaviors. Basic safety messages can be sent periodically. As used herein, the term “Basic Safety Message” refers to Basic Safety Messages (BSM), which may be used in North America, Cooperative Awareness Messages (CAMs), which may be used in Europe, and other Intelligent Transportation System (ITS) protocols. or other similar messages that may be used in accordance with technical standards. V2X nodes can also transmit other V2X messages related to other services. For example, a V2X node may send messages related to toll collection or toll collection operations, such as a Tolling Upload Message (TUM) or similar messages, which may include the identifier of the V2X node and the location, route, and other information about the V2X node. Information can be transmitted. As another example, a V2X node may send an emergency or mayday message, such as a SAE J2735 message, which may include the identifier of the V2X node and the V2X node's location, speed, heading, latitude, longitude, altitude, and other information about the V2X node. Can be transmitted. As another example, V2X messages used by emergency responders or emergency service providers (e.g., police, fire departments, emergency medical technicians, etc.) may include location information, identifier(s) of vehicles such as V2X nodes, etc. there is. The information content of various V2X messages may overlap or overlap to some extent.

[0026] V2X communication systems are typically bandwidth constrained and may include multiple participating entities, including many vehicles, roadside units, gantry units, and other network elements, each transmitting multiple V2X messages. there is. Reducing the redundancy of information carried by V2X messages can reduce the bandwidth overhead caused by V2X messages and reduce the computational overhead of processing each V2X message. However, typical V2X node security mechanisms separate “sandbox” applications from each other and require separate permissions (separately issued digital signatures or other suitable may be managed by security measures). Therefore, it is not easy to combine messages configured for different services (eg BSM, toll, emergency services, etc.) and apply a single digital signature to cover both messages or all messages. Additionally, the simple combining of messages configured for different services may raise privacy concerns because applying a single digital signature to many V2X messages may prevent any device authorized to view one of the V2X messages. This is because the content of all V2X messages can be exposed.

[0027] Various embodiments store V2X information within an intelligent transportation system (ITS) within the ITS (e.g., other vehicles, roadside units (RSUs), etc.) or to other networks (e.g., the Internet, private networks, etc.). Includes methods and mechanisms for efficiently communicating with other network elements, which may be network elements within the network. To include IDS network elements as well as network elements that may be in non-ITS systems, the term "network node" is used herein to refer to network elements through which a V2X node can transmit V2X messages according to various embodiments. It is used to Accordingly, a “network node” may be any computing device in a network configured to receive V2X messages from a V2X node, including (but not limited to) V2X nodes.

[0028] Various embodiments allow a V2X node (e.g., a vehicle's V2X onboard equipment, mobile phone, laptop, tablet, or other suitable computing device) to connect to a network node (e.g., another vehicle, an RSU, or a gantry unit (e.g. For example, it communicates with a toll gantry unit) to utilize the information provided by the V2X node for the first service in performing operations for the second service provided by the network node or related to the network node.

[0029] As mentioned above, a V2X node may transmit various V2X messages that may contain overlapping information content. For example, a toll collection or toll collection system (tolling system) may accurately position a V2X node's specific lane location lanes so that the system can charge the V2X node the appropriate fare or toll (i.e., "lane-level accuracy"). You may have to decide. A typical toll message from a V2X node may include V2X node identity information, account number or other financial information, location information, as well as other information about the V2X node. At the same time, the V2X node performing the maneuver may transmit one or more V2X messages to coordinate with other vehicles to ensure that the maneuver can be performed safely and efficiently. Additionally, all V2X-equipped vehicles routinely share information such as maneuvering information, location information, and other basic safety messages.

[0030] Various embodiments include methods, V2X nodes, and network nodes configured to perform methods of communicating V2X node information in a manner that improves efficiency and reduces processing and communication link overhead required for handling V2X messages. do. In some embodiments, a V2X node (e.g., a V2X processing device of a vehicle's V2X onboard equipment) sends a first V2X message associated with a first service and including an identifier of the second service for reception by the network node. A second V2X message may be transmitted, associated with the second service, and including an identifier of the first service configured to enable the network node to use information from the first V2X message to the second service. In various embodiments, including the identifiers of the services with the V2X messages of other services allows the receiving network node to establish an association between messages from the V2X node for the first service and messages from the V2X node for the second service. can be created, thereby enabling the network node to use the information provided by the V2X node in the message for the first service when performing operations on behalf of the V2X node for the second service. In this way, the V2X node sends a V2X message for the second service that includes an identifier for the first service, instead of including information in the V2X message for the second service that is overlapping with information in the V2X message for the first service. can be created. For example, a V2X node can transmit basic safety messages containing node identification information and the location of the V2X node. The V2X node also transmits a toll message that references the basic safety message, allowing the receiving network node to use identification and/or location information from the basic safety message.

[0031] The terms “first message” and “second message” are used to distinguish each message and are not intended to require an order or sequence of messages or to limit the message to just two messages. Additionally, any number of “first” messages and any number of “second” messages may be sent. Additionally, additional messages, generally referred to herein as “third messages,” may also be sent incorporating elements of the various embodiments. Similarly, the terms “primary service” and “secondary service” are used to distinguish each service. In some embodiments, information from the first service may be used to perform the operation of the second service. In some embodiments, information of the first service may be provided in a message of the first service. In some embodiments, information from the second service may be used to perform the operation of the first service. In some embodiments, information about the second service may be provided in a message of the second service.

[0032] In some embodiments, a V2X node may generate an identifier from a signing certificate associated with the service. In some embodiments, the V2X node may generate an identifier of the first service from the signature certificate of the first service associated with the V2X node, and generate the identifier of the second service from the signature certificate of the second service associated with the V2X node. You can. In this way, each V2X message can contain an identifier that is secure and verifiable by the receiving network node.

[0033] In some embodiments, the V2X node may generate a hash of the signing certificate of the first service to generate an identifier of the first service, and generate a hash of the signing certificate of the second service to generate an identifier of the second service. can be created. In some embodiments, after the association between the messages for the first service and the second service is established, the V2X node shortens the second service to the first service to further reduce the amount of data in each V2X message. You can create a truncated or truncated identifier. In some embodiments, the truncated identifier may be as small as the last 3 or 4 bytes of the full hash identifier. In some embodiments, a V2X node may generate a truncated hash of the first service's signing certificate (e.g., the last 3 or 4 bytes of the full hash certificate) and a truncated hash of the second service's signing certificate. A hash can be generated (e.g., the last 3 or 4 bytes of the entire hashed certificate). In some embodiments, a receiving network node can easily identify the truncated identifier of each service's signing certificate in relation to the full or larger identifier of each service's signing certificate.

[0034] In some embodiments, a V2X node may determine whether a similar certificate has been used by another vehicle or network node within a threshold radius and/or a threshold time period. In response to determining that a similar certificate has not been used by another vehicle or network node within a threshold radius and/or threshold time period, the V2X node may generate and use a truncated identifier for the data contained in the message for the service. .

[0035] In some embodiments, a V2X node may intersperse V2X messages containing the full or larger identifier of the service among V2X messages using the truncated identifier of the service. In this way, sending V2X nodes can be locally unambiguous about the signing certificates associated with V2X nodes and services, while also being cryptographically more secure by periodically including larger identifiers. For example, an attacker can record communication sessions (i.e., V2X messages related to services) and replace V2X messages signed with the V2X node's signature with messages signed with the attacker's certificate. Although an attacker can identify available certificates based on truncated identifiers, it is impossible to identify certificates with longer identifiers. In this way, interspersing V2X messages containing larger identifiers of the service can increase the security of V2X communications.

[0036] According to some embodiments, the first V2X message may be a basic safety message. In some embodiments, the second V2X message may be related to another service. For example, the second V2X message may be a toll message (e.g., for a toll collection or toll collection system), a parking access message (e.g., for a parking payment system), a road condition message (e.g., for another messages about vehicles, RSUs, or network nodes about traffic, observed vehicle behavior, hazardous road conditions such as road damage, ice or flooding, etc.), geonetworking messages (e.g. for use in geonetworking messages or messaging systems) ), an emergency responder message (e.g., police, fire department, emergency medical technician or other emergency responder system), or another suitable message or messaging system.

[0037] In various embodiments, a network node may receive a first V2X message from a V2X node, which is associated with a first service and includes an identifier of the second service, and is associated with a second service and includes an identifier of the first service. A second V2X message containing can be received from the V2X node. In some embodiments, the network node may create an association of the V2X node, the first service, and the second service that allows the network node to use information from the first V2X message to the second service. In some embodiments, a network node may use information from the first V2X message for a second service. In some embodiments, the network node may obtain information about the V2X node from the first V2X message, and use the information about the V2X node obtained from the first V2X message to operate on the V2X node related to the second service. can be performed.

[0038] In some embodiments, the network node may determine whether the first V2X message and the second V2X message were received within a threshold time period. In response to determining that the first V2X message and the second V2X message have been received within a threshold time period, the network node may use information from the first V2X message for the second service. In this way, the network node can not only increase the security of the association between V2X messages of the first and second services, but also use data that may no longer be accurate (e.g. the location of the moving vehicle). You can avoid doing this.

[0039] In this manner, various embodiments are configured to perform methods for communicating V2X information in V2X messages in a manner that improves efficiency and reduces the processing and communication link overhead required to handle such V2X messages. , V2X processing devices, and network elements.

[0040] For ease of reference, some of the embodiments are described in this application with reference to a vehicle using vehicle-to-everything (V2X) systems and protocols. However, it should be understood that various embodiments include some or all of V2X or vehicle-based communication standards, messages or technologies. As such, nothing in this application should be construed as limiting the claims to V2X systems, basic safety messages (BSMs), or V2X messages unless explicitly stated as such in the claims. Additionally, embodiments described herein may refer to an in-vehicle V2X processing system. Other embodiments contemplate that the V2X processing system may operate on or be included in mobile devices, mobile computers, roadside units (RSUs), and other devices equipped to monitor road and vehicle conditions and engage in V2X communications. do.

[0042] By sharing vehicle location, speed, direction, braking and other information, vehicles can maintain safe separation and identify and avoid potential collisions. For example, a trailing vehicle 12 that receives basic safety messages 114 from a leading vehicle 16 can determine the speed and position of vehicle 16, thereby ) allows matching speed and maintaining a safe separation distance (20). By receiving notifications through basic safety messages 114 when the preceding vehicles 16 apply the brakes, the V2X equipment 102 of the following vehicle 12 applies the brakes at the same time even if the preceding vehicle 16 suddenly stops. Thus, a safe separation distance (20) can be maintained. As another example, the V2X equipment 104 in a truck vehicle 14 receives basic safety messages 112, 116 from two vehicles 12, 16, and thus moves the truck vehicle 14 to an intersection to avoid a collision. You can indicate that you need to stop at . Additionally, each of the vehicle V2X onboard devices 102, 104, and 106 may communicate with each other using any of a variety of proximity communication protocols.

It can be composed of commands. Additionally, the processor 205 may be coupled to an output module 208 that may control in-vehicle displays and an input module 207 that may receive information from vehicle sensors as well as driver inputs.

In various embodiments, the V2X processing device 202 may process a plurality of information, such as an in-vehicle network 210, an infotainment system 212, various sensors 214, various actuators 216, and a radio module 218. Information can be received from sources.

FIG. 3B is a conceptual diagram illustrating an example message flow 350 suitable for implementing various embodiments. 1-3B, V2X messages 300 and message flow 350 are sent to a vehicle processing system (e.g., 204) of a V2X node (e.g., vehicle 12, 14, 16, 202). ) and network nodes (e.g., other vehicles 12, 14, 16, 220, RSU 132, network elements 134, 136).

[0049] The first V2X message 302 may include information such as payload (eg, data or information) and/or metadata 304 related to the first service. The first V2X message 302 may include one or more certificates 306 associated with the first service. The first V2X message 302 may also include an identifier of the second service 308. The first V2X message 302 may include a signing certificate for the first service 310. The first V2X message 302 may include or be associated with a digital signature (i.e., the first V2X message 302 may be digitally signed). In some embodiments, the first V2X message 302 may be a basic safety message.

V2X messages for each of the first service and the second service may include the identifier of the other service. For example, the V2X message 352 of the first service may include a longer identifier of the second service, and the V2X message 354 of the second service may include a longer identifier of the first service. The inclusion of an identifier for a different V2X service in each V2X message can enable a receiving device (e.g., a network node) to associate two services and/or messages from two services to a V2X node. there is. In some embodiments, a network node may create an association of a V2X node, a first service, and a second service. This association can enable the network node to use information from the first V2X message when performing operations of the second service for the V2X node.

[0052] V2X messages transmitted/received after V2X messages 352 and 354, such as V2X messages 356 and 358, may include truncated identifiers of other services.

In some embodiments, the truncated identifier may be a truncated hash of another service's certificate. In some embodiments, the truncated identifier may contain sufficient information to uniquely identify the longer identifier. For example, a truncated hash of a certificate may contain sufficient information (e.g., may be a string of sufficient length) to uniquely identify the full length or full-size hash of the certificate.

[0053] In some embodiments, a V2X node may intersperse V2X messages containing the full or larger identifier of the service among V2X messages using the truncated identifier of the service. For example, the V2X messages 360, 362, and 366 may include a truncated identifier of the first service, and the V2X message 364 placed between the V2X messages 362 and 366 is the first service. may contain longer identifiers. In various embodiments, larger identifiers are cryptographically more secure than truncated identifiers. In this way, by periodically including longer identifiers, V2X nodes can reduce the overall amount or volume of data transmitted over the V2X node communication link while maintaining a sufficient level of security to deter attackers.
