Publication number: 20250104558Abstract: A control signal generated based on real-time vehicle sensor data from multiple vehicles on a road segment is received by a processor of a vehicle. The processor uses at least a portion of the control signal to generate an adaptive cruise control parameter that includes a speed parameter and a headway parameter. The processor configures a cruise control module of the vehicle to use the adaptive cruise control parameter. The control signal may be generated using a machine-learning model trained to receive traffic data that includes at least one of traffic density, a distance between the vehicle and the road segment, a distance between the vehicle and a congested location, data indicative of traffic speed, and respective speeds of other vehicles proximate to the vehicle.Type: ApplicationFiled: December 9, 2024Publication date: March 27, 2025Inventors: Liam Pedersen, Fang-Chieh Chou, Viju James, Najamuddin Mirza Baig, Katsuhiko Hirayama, Abdul Rahman Kreidieh

Publication number: 20250076874Abstract: A system may receive a video stream from a camera of a vehicle in a transportation network. The system may also receive an input indicating an acceleration and a steering angle of a simulated lead vehicle. The system may determine a pose of the simulated vehicle relative to a home pose based on the acceleration input and the steering input, and display an overlay of a representation of the simulated vehicle in the video stream at pixel coordinates based on the pose. The system may determine, from the pixel coordinates, spatial coordinates of the simulated vehicle in the transportation network, wherein the spatial coordinates are relative to at least one of the transportation network or the camera. The system may transmit the spatial coordinates to the vehicle to cause the vehicle to follow a path based on the spatial coordinates.Type: ApplicationFiled: August 31, 2023Publication date: March 6, 2025Inventors: Mark Fischer, Viju James, Christopher Ostafew, Julie D.
