Abstract: A method and system for dynamically configurable remote data collection from a subject vehicle in response to a task-specific data query is described. This includes the subject vehicle, and a second controller that wirelessly communicates with the subject vehicle, wherein the second controller is an off-board controller that is located remote from the subject vehicle. In one embodiment, the off-board controller is an element of a cloud computing system.

Abstract: A method includes determining that the vehicle is approaching a garage and receiving a video from a garage camera and determining a frame difference per pixel with respect to time as the vehicle moves into the garage and counting a number of rows of pixels with no changes as the vehicle moves into the garage using the frame difference per pixel. Further, the method includes comparing the number of rows of pixels with no changes as the vehicle moves into the garage with a predetermined row threshold to determine whether the number of rows of pixels with no changes with respect to time as the vehicle moves into the garage is less than or equal to the predetermined row threshold and commanding a display to provide a notification indicative that the vehicle is properly parked in the garage.

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: A system for routing a vehicle based on roadway characteristics includes a global navigation satellite system (GNSS) for determining a geographical location of the vehicle, a vehicle communication system for communicating with at least one external system, and a vehicle controller in electrical communication with the GNSS and the vehicle communication system. The vehicle controller is programmed to determine a vehicle length and a vehicle width, receive a navigation request from an occupant of the vehicle, and determine a navigation route using at least the GNSS and the vehicle communication system in response to receiving the navigation request, where the navigation route is based at least in part on the vehicle length and the vehicle width.

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 method for lateral assist includes receiving work-zone data. The work-zone data includes information about a location of a work zone and a geometry of the work zone. The method further includes determining a route of a vehicle using the work-zone data. Determining the route path of the vehicle includes selecting a lane segment using the work-zone data. The lane segment is adjacent to the work zone. Determining the route path further includes determining a lane departure tolerance for the lane segment previously selected using the work-zone data. The method further includes commanding the vehicle to move within the lane departure tolerance along the lane segment previously selected.
