摘要： Position enhancement for vehicle positioning is provided. Vehicle-to-everything (V2X) messages are received from a roadside unit (RSU) to an onboard unit (OBU) of a vehicle via a transceiver of the vehicle, the V2X messages indicating a location of the RSU. Image sensors of the vehicle are utilized to capture sensor data of the RSU. A current position of the vehicle is updated to a corrected current position of the vehicle based the RSU as shown in the sensor data and the location of the RSU indicated in the V2X messages.

摘要： A toll advertisement message (TAM) broadcast from a roadside unit (RSU) is received by a vehicle via V2X communication, the TAM indicating geographic locations of lanes of a roadway for which tolls are due and cost information for traversing the lanes of the roadway. A heading of the vehicle is determined in relation to a TAM reference point indicating a geographic location of a toll gantry. A toll zone boundary region for the vehicle is identified by filtering the geographic locations of the lanes in the TAM to include only those lanes in a travel direction consistent with the heading. A lane straddling algorithm is utilized to identify, for each of the lanes in the travel direction, a respective percentage within each lane that the vehicle is traveling. A tolling usage message (TUM) is sent via the V2X communication, indicating to the RSU the percentage lane usage of the vehicle.

摘要： A toll advertisement message (TAM) broadcast from a roadside unit of a roadway is received. The TAM may include a public key of a toll charger cloud. Responsive to receipt of the TAM, a tolling usage message (TUM) is sent. The TUM may include information encrypted with a public key of a toll service provider, information encrypted with the public key of the toll charger cloud, and a public key of the telematics control unit. Responsive to broadcast of the TUM, a toll usage message acknowledgement (TUM-ACK message. A toll receipt message (TRM) is also received. The TRM is encrypted with the public key of the telematics control unit. The TRM is decrypted using a private key of the telematics control unit corresponding to the public key of the telematics control unit.

摘要： An on-board unit (OBU) of a vehicle receives one or more data messages indicative of intersection geometry for an upcoming intersection along a roadway being traversed by the vehicle and traffic control status of a traffic control of the intersection. An outbound direction for the vehicle through the intersection is identified. A first traffic message is sent to preempt the traffic control to allow the vehicle to perform a maneuver to traverse the intersection in the outbound direction. The maneuver is indicated as complete and a second traffic message is sent to discontinue the preempt of the traffic control.

摘要： Toll advertisement messages (TAMs) are broadcast via V2X communication, each of the TAMs indicating geographic locations of lanes of a roadway for which tolls are due and cost information for traversing the lanes of the roadway. A tolling usage message (TUM) is received via the V2X communication, the TUM indicating, to a roadside unit (RSU), information regarding a vehicle entering one of the lanes of the roadway and a unique random account identifier to be used by the RSU to identify the vehicle. A toll receipt message (TRM) is broadcast via the V2X communication, the TRM including the unique random account identifier and indicating, to the vehicle, a final cost charged to the vehicle for access to the one of the lanes of the roadway.

摘要： Smart tolling for vehicles is provided. A toll advertisement message (TAM) is received by a vehicle, broadcast from a road-side unit (RSU) via V2X communication, the TAM defining a plurality of toll road tariff data elements, each of the toll road tariff data elements specifying a set of tolling factors indexed by a unique toll context identifier. Roadway usage of the vehicle is determined. A charge for the roadway usage is determined according to the set of tolling factors of the TAM. A toll usage message (TUM) is sent via the V2X communication, the TUM indicating, to the RSU, the tariff for the roadway usage of the vehicle.

摘要： An on-board unit of a vehicle includes first and second transceivers. A processor of the vehicle monitors transmissions received from the first and second transceivers, receives an incoming message sent to the processor from the first transceiver, the incoming message being designated for distribution to roadway participants, identifies based on the monitored transmissions whether the second transceiver is in communication with devices of roadway participants available to receive outgoing messages, and if so, construct an outgoing message based on the incoming message and send the outgoing message via the second transceiver, and monitors vehicle network bus traffic to identify a current speed of the vehicle, and responsive to the vehicle moving at least a threshold speed, construct and send vehicle-information outgoing messages including roadway observations of the vehicle, using the first transceiver and the second transceiver, the vehicle-information outgoing messages being designated for distribution to the roadway participants.
