US Patent 9818299 Vehicle-to-vehicle intersection navigation control

A host vehicle computer is programmed to receive intersection arrival data via vehicle-to-vehicle communications from one or more secondary vehicles. The computer assigns priority to each of the secondary vehicles based on the intersection arrival data and identifies one of the secondary vehicles as an immediately preceding vehicle. Upon receiving a ready signal clearance from the immediately preceding vehicle, the computer actuates a powertrain of the host vehicle, causing the host vehicle to proceed into, and through, the intersection.
