Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A toll advertisement message is received, via a V2X transceiver of a vehicle, defining a metered zone in which tolls are charged. Input data indicative of a current position of the vehicle with respect to the metered zone is determined. A state machine is utilized to determine tolled roadway usage of the vehicle according to the metered zone and the current position. A toll usage message indicative of the tolled roadway usage is provided via the V2X transceiver.

Abstract: 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.

Abstract: An on-board unit of a vehicle includes first and second transceivers.

Abstract: Systems, methods, and computer-readable media are directed to increasing the accuracy of vehicle positioning. Example methods may include transmitting, by an on-board unit, a message including a motion information associated with the vehicle; determining, by a processor, a signal comprising modulating radiation, the signal identifying the vehicle; receiving, by the on-board unit, an additional message, the additional message including location information and a timestamp; and determining a location of the vehicle based on the location information.

Abstract: A road-side unit includes a first transceiver configured to communicate using a first vehicle-to-infrastructure protocol and a second transceiver configured to communicate using a second vehicle-to-infrastructure protocol, the first vehicle-to-infrastructure protocol and the second vehicle-to-infrastructure protocol being incompatible with one another. The road-side unit further includes a processor programmed to monitor transmissions from the first and second transceivers, receive an incoming message sent to the processor from the first transceiver, the incoming message being designated for distribution to roadway participants, identify 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.

Abstract: A vehicle-to-vehicle communication system may include at least one light and at least one controller configured to receive vehicle data indicative of vehicle traffic from a vehicle via vehicle-to-vehicle communication and to control a light state based on the vehicle traffic, wherein the light state changes when the vehicle data indicates vehicle traffic falling outside of a traffic range

Abstract: A system includes a processor configured to detect a vehicle key-off. The processor is also configured to delete from a primary memory (“internal memory”) of an electronic control unit an existing software version for which a new software version update exists in a secondary memory of the ECU. The processor is further configured to load the new software version from the secondary memory (“external memory”) into the primary memory and upon detection of a failure during the load, delete the new software version from the primary memory and reload the existing software version from the secondary memory.
