摘要： A hybrid positioning system for a vehicle includes one or more controllers in wireless communication with a plurality of surrounding vehicles located in an environment surrounding the vehicle and a cellular software defined network including an edge positioning function. The one or more controllers execute instructions to receive, from the plurality of surrounding vehicles, relative position measurements that are each indicative of a position of one of the plurality of surrounding vehicles relative to the vehicle, wherein the relative position measurements are received by the one or more controllers in real-time. The one or more controllers receive a precise global position of the vehicle and the plurality of surrounding vehicles from the edge positioning function of the cellular software defined network, and fuse together the relative position measurements and the precise global position of the vehicle to determine a precise position of the vehicle.

摘要： A method for maintaining network quality of service (QoS) for in-vehicle applications includes receiving historical network speed data from a plurality of remote actors and mapping a network speed along the road ahead of the host vehicle using the historical network speed data from the plurality of remote actors and identifying a bad network coverage zone along the road ahead of the host vehicle. The method further includes determining an amount of time that the host vehicle will spend in the bad network coverage zone, determining an amount of application data to cache as a function of the amount of time that the host vehicle will spend in the bad network coverage zone, and caching the amount of application data before the host vehicle reaches the bad network coverage zone.

摘要： A latency masking system for use in an autonomous vehicle (AV) system includes a sensors module providing sensor data from a plurality of sensors. The sensor data includes image frames provided by a vehicle camera and vehicle motion data. A wireless transceiver transmits the sensor data to a remote server associated with a network infrastructure and receives remote state information derived from the sensor data. An on-board function module receives the sensor data from the sensors module and generates local state information. A state fusion and prediction module receives the remote station information and the local state information and updates the local state information with the remote state information. The state fusion and prediction module uses checkpoints in a state history data structure to update the local state information with the remote state information.
