Abstract: A method for video streaming includes receiving video streaming data from a wireless camera. The camera is in wireless communication with a vehicle. The method further includes identifying a stable video region in the video streaming data received from the wireless camera, detecting stale video content in the video streaming data based on the stable video region, and in response to detecting the stale video content in the video streaming data, providing a notification to a vehicle occupant, via a display of the vehicle. The notification is indicative that a video streamed in the display of the vehicle is stale. The method described in this paragraph improves video and vehicle technology by identifying stale video content and notifying the vehicle occupant that the video is stale, thereby preventing the vehicle occupant from relying on stale video content.

Abstract: 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.

Abstract: A system, method and server for a controlling a relation between a vehicle and traffic flow over a road segment. The system includes a telemetric device of the vehicle and a processor of the server. The telemetric device obtains telemetric data related to the road segment being traversed by the vehicle. The processor determines a property of the road segment based on the telemetric data and a road profile for the road segment, determines a disruption score indicative of a level of disruption in the traffic flow for the road segment based on the property, and outputs a notification signal when the disruption score is above a selected disruption threshold. The notification signal is usable for controlling the relation between the vehicle and the traffic flow.

Abstract: A system for bandwidth saving for wireless cameras using motion vectors includes wireless cameras disposed within the vehicle, and capturing input image data. A control module, having a processor, memory, and input/output (I/O) ports, executes control logic stored in memory. A first control logic receives, real-time input image data from the cameras. A second control logic processes the input image data to maintain (Wi-Fi) bandwidth utilization within the vehicle below a predetermined threshold and maintains and maximizes real-time image data streaming quality through semantic segmentation and background memorization. A third control logic generates an output including background and foreground image portions. The output is transmitted to a human-machine interface (HMI) within the vehicle and periodically replaces the background portion with a cached background scene that is transmitted to the HMI.

Abstract: A first closed lane segment file including a first lane change histogram and a lane closure start point associated with a closed lane segment of a first lane of a road is received from a lane change data aggregation system at a lane change management system. The first lane change histogram includes a distribution of a plurality of lane change points received from vehicles that previously engaged in a lane change from the first lane to a second lane of the road in response to the closed lane segment. A lane change control point is determined based on the first lane change histogram at the lane change management system. A command is issued from the lane change management system to an ADS of the autonomous vehicle to initiate a lane change from the first lane to the second lane at the lane change control point.

Abstract: An automatic lane change activation system includes a host vehicle including an in-vehicle computer. A telematics module communicates global positioning system (GPS) data between the computer and the telematics module. A host vehicle display device receives signals from the computer. A visual system status is presented to a host vehicle user by the display device including an information screen presenting a roadway information message, a control screen presenting an opportunity message identifying to the user an opportunity to switch the host vehicle from a first roadway lane into a second roadway lane, and a lane change directional arrow to indicate a path for the host vehicle to take. A motion control module in the host vehicle receives control signals from the computer including a lane change execution signal to initiate and control vehicle automatic lane changes in a non-congested area of a roadway for the host vehicle.

Abstract: An event scheduling system for collecting image data related to one or more events by one or more autonomous vehicles includes a centralized scheduling system in wireless communication with one or more autonomous vehicles. Each autonomous vehicle collects the image data related to the one or more events while following a unique travel schedule. The centralized scheduling system executes instructions to determine the unique travel schedule for a specific autonomous vehicle, where the unique travel schedule directs the specific autonomous vehicle to the specific location of the filtered event to collect the image data.
