    摘要: A vehicle includes a controller. The controller is programmed to broadcast state information for the vehicle and receive state information from other vehicles; identify a contested roadway area for the vehicle and another of the vehicles based on expected future paths of the vehicle and the other vehicle calculated per the state information; and update a ledger with an indication of which of the vehicle or the other vehicle is agreed to proceed through the contested roadway area.

    摘要: 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.

    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.
