Abstract: A method for operating an advanced driver assistance (ADAS) system of a motor vehicle includes a vehicle controller receiving, from side and end cameras mounted to the vehicle, camera signals indicative of real-time images of outboard-facing side and end views of the vehicle. The controller determines a region of interest (ROI) inset within each end/side view within which is expected foreign objects and/or hazards. These ROIs are analyzed to detect if a foreign object/hazard is present in the vehicle's end and/or side views. Responsive to detecting the foreign object/hazard, movement of the foreign object/hazard is tracked to determine if the foreign object/hazard moves towards or away from the vehicle's underbody region. If the foreign object/hazard moves to the underbody region, control signals are transmitted to the vehicle's propulsion and/or steering system to automate preventative action that prevents collision of the vehicle with and/or removes the foreign object/hazard from the underbody.

Abstract: Vision sensing systems and methods that mitigate flicker and associated artifacts. The system includes a camera module that controls operation of a camera onboard a mobile platform and generates camera data therefrom, wherein the camera data comprises a sequential plurality of frames An exposure lock module is configured to: communicate with the camera module to receive the camera data; analyze the camera data to identify a blackout; utilize machine learning to quantify a frequency of blackouts in the camera data; generate a vision sensor command for anticipating future blackouts as a function of the frequency of blackouts; and supply the vision sensor command to the camera module. An enhanced exposure control module utilizes the vision sensor command to mitigate flicker and associated artifacts, thereby providing image stabilized enhanced frames.

Abstract: A computer-implemented method is executed by data processing hardware of a display calibration system in communication with a camera system of a motor vehicle that has a vehicle display. The method includes computing a first gamma value for a vehicle display based on at least one display specification or a vehicle statistic. Additionally, the method includes receiving a display look-up table, which is modified based on the computed first gamma value to generate a transformation look-up table. Image data from the camera system is received, and the transformation look-up table is applied to the image data to generate transformed image data. Simulated image data is generated based on the transformed image data, and this simulated image data is rendered at a display of the display calibration system. The rendered display corresponds to the vehicle display.

Abstract: Systems and methods for controlling a vehicle are provided. The systems and methods receive a frame of visible image data from at least one camera of the vehicle and a frame of invisible perception data from a perception sensor. The systems and methods fuse the frame of invisible perception data and the frame of visible image data to provide a fused frame of perception data. Object detection, classification and tracking are performed using a neural network based on the fused frame of perception data to provide object detection data. Steering, propulsion and/or braking of the vehicle are controlled based on the object detection data.

Abstract: An in-vehicle violence detection system includes a speech and non-speech audio recognition module capturing occupant threat words and non-speech audio events. In-vehicle accelerometers generate data analyzed in a shaking movement recognition module. A heart rate and breathing rate detection module measures physiological changes in occupant heart rates and breathing rhythms. An in-vehicle semantic scene recognition module analyzes occupant non-verbal interactions. Occupant threat indicators including an audible threat indicator are generated by the speech and non-speech audio event recognition module. Visual threat indicators are generated by the in-vehicle semantic scene recognition module. Physiological threat indicators are generated by the heart rate and breathing rate detection module. Vibration-based threat indicators are generated by the shaking movement recognition module. The four threat indicators are fused to estimate a threat level, consolidated by incorporating contextual information including a vehicle location and time. Different actions are taken based on the consolidated threat level.

Abstract: A method for surveilling with a vehicle includes receiving an area-of-interest data from a vehicle user. The area-of-interest data delineates a virtual fence around the vehicle. The virtual fence is boundary of an area of interest around the vehicle. The vehicle is parked adjacent to an infrastructure. The method further includes receiving sensor data from a sensor of the vehicle that is monitoring the area of interest. Further, the method includes detecting a predetermined activity by a predetermined object of interest within the area of interest based on the sensor data received from the sensor of the vehicle. Also, the method includes notifying the vehicle user of the predetermined activity sensed using the sensor of the vehicle.
