Abstract: A method for executing a V2V data exchange includes determining if a host vehicle is communicatively connected to a seeder vehicle, and transmitting a prompt between the two vehicles to initiate a resource discovery process. The seeder vehicle wirelessly transmits to the host vehicle a Bloom filter with multiple file IDs mapped to a bit array. Each file ID has a corresponding file version number encoded to the bit array. The method then determines if a local file ID of an existing file stored via the host vehicle is a member of the Bloom filter; if so, the host vehicle determines if a remote file version number encoded to a counterpart file ID is newer than a file version number of the local file ID. If the remote file version number is newer, the seeder vehicle transmits the data file associated with the counterpart file ID to the host vehicle.

Abstract: Technical solutions are described for generating a pedestrian detection warning in a vehicle. An example method includes constructing, by a vehicle controller, a pedestrian zone based on pedestrian information that is received from a traffic controller. The method further includes computing, by the vehicle controller, a vehicle trajectory that predicts a path for the vehicle. The method further includes determining, by the vehicle controller, a minimal distance between the pedestrian zone and the vehicle trajectory. The method further includes predicting, by the vehicle controller, a time to collision by computing a time for the vehicle to reach a location corresponding to the minimal distance along the vehicle trajectory. The method further includes in response to the time to collision being below a threshold, generating, by the vehicle controller, a warning for an operator of the vehicle.

Abstract: A method in a vehicle includes receiving a vehicle-to-infrastructure (V2I) message transmitted from a communication system affixed to infrastructure at a location. The V2I message includes at least one category of information among a plurality of categories of information and the plurality of categories of information include map-based information and road safety information. The method also includes determining, based on performing at least one type of verification, whether a misbehavior has occurred with respect to the V2I message. The misbehavior indicates incorrect information in the V2I message. A counter is maintained of a number of times the misbehavior has occurred with respect to the V2I message at the location, and the misbehavior is reported based on the counter.
