  • Publication number: 20210143924
    Abstract: A system comprises a computer including a processor. The processor receives from each of a plurality of vehicles within a region, a respective plurality of messages and identifies for each of the plurality of vehicles, a respective communications discontinuity during which an expected message fails to be received from the respective vehicle. The processor determines, for each communications discontinuity, discontinuity edge locations at each of a beginning of the communications discontinuity and an end of the communications discontinuity. The processor further determines an interference node location based on the discontinuity edge locations.

  • Publication number: 20210141100
    Abstract: A computer is programmed to determine a localization of a first vehicle, including location coordinates and an orientation of the first vehicle, based on first vehicle sensor data, and to wirelessly receive localizations of respective second vehicles, wherein a first vehicle field of view at least partially overlaps respective fields of view of each of the second vehicles. The computer is programmed to determine pair-wise localizations for respective pairs of the first vehicle and one of the second vehicles, wherein each of the pair-wise localizations defines a localization of the first vehicle relative to a global coordinate system based on a (a) relative localization of the first vehicle with reference to the respective second vehicle and (b) a second vehicle localization relative to the global coordinate system, and to determine an adjusted localization for the first vehicle that has a minimized sum of distances to the pair-wise localizations.

  • Patent number: 10979930
    Abstract: A system comprises a computer and a memory. The memory stores instructions to determine that a vehicle communication channel busy ratio exceeds a threshold, and then, based upon determining that the channel busy ratio exceeds the threshold, to classify a traffic condition for a road segment within a coverage area of an infrastructure element based on at least one of a traffic density and a status of a traffic light. The memory further includes instructions to determine a broadcast policy for the road segment based on the channel busy ratio exceeding the threshold and the classified traffic condition, wherein the broadcast policy is selected from a set of policies that includes (1) a periodic broadcast of messages and (2) a broadcast limited to specified messages.

  • Patent number: 10977939
    Abstract: An infrastructure element includes a computer that includes a processor and a memory. The memory stores instructions executable by the processor such that the computer is programmed to classify a traffic condition of a road segment based on data received from an object detection sensor with a field of view including the road segment and that is communicatively connected to the computer. The computer is programmed to broadcast, to an area including the road segment, a vehicle-to-vehicle communication parameter, determined based on the classified traffic condition and specifying one or more of (i) a channel identifier, (ii) a transmission rate, (iii) a transmission power, or (iv) a message size.

  • Publication number: 20210101606
    Abstract: Respective planned reference velocities of a reference vehicle are received for each of a plurality of time steps including a current time step. Respective sensed velocities of a subject vehicle for each of the time steps are determined from sensor data. Respective distances between the reference vehicle and the subject vehicle are determined for each of the plurality of time steps. A number of intervening vehicles between the reference vehicle and the subject vehicle is determined. Based on the planned reference velocities of the reference vehicle, the sensed velocities of the subject vehicle, the distance, and the number of intervening vehicles, a future velocity of the subject vehicle is predicted at a time step that is after the current time step.
