Abstract: A multimedia system is provided for a scalable infotainment system of a motor vehicle. The scalable infotainment system includes a camera, which is releasably attached to the motor vehicle and supports camera software components for generating a media signal. The multimedia system includes a media player and a computer attached to the motor vehicle. The computer has a processor and a non-transitory computer readable storage medium, which stores player software components including multiple streaming protocols used by the media player to play a media stream. The processor is programmed to transmit to the camera a player setup signal including data associated with the player software components. The processor is further programmed to receive from the camera a media signal associated with a media stream generated by the camera by using a common one of the streaming protocols supported by the camera and the media player.

Abstract: A system for sharing sensor data between a vehicle and a plurality of remote system generally includes a vehicle communication system, a three-dimensional (3D) sensor, and a controller. The controller is programmed to generate an initial 3D point cloud using the 3D sensor, generate an occupancy grid map based on the initial 3D point cloud, and select a producer remote system to provide data for a cell of the occupancy grid map classified as a first blindspot. The controller is further programmed to send a data request to the producer remote system using the vehicle communication system, receive data from the producer remote system including information about the cell of the occupancy grid map classified as the first blindspot, generate a merged 3D point cloud by merging the data received from the producer remote system with the initial 3D point cloud, and identify objects using the merged 3D point cloud.

The system comprises a driver behavior module that receives from the vehicle event data captured by a plurality of sensors in the vehicle and identifies at least one of a plurality of driver behaviors. A behavior characterization module receives from the driver behavior module the at least one identified driver behavior and characterizes the at least one identified driver behavior into at least one of a plurality of behavior categories.

Abstract: A sequence of images and a vehicle location associated with each of the images is received at a traffic light ROI management system. At least one traffic light is detected in each image. A ECS traffic light ROI is defined for each image. The ECS traffic light ROI encloses the detected traffic lights. A visual feature template is generated for each image. The visual feature template is based on the ECS traffic light ROI for the image. Each visual feature template is mapped to the vehicle location associated with the image to a HD map. The HD map is transmitted to an autonomous vehicle to enable the autonomous vehicle to identify a real-time traffic light ROI in a real-time image based on a match between a first visual feature template and real-time visual features of the real-time image at the vehicle location associated with the first visual feature template.

Abstract: A scan matching and radar pose estimator for determining a final radar pose for an autonomous vehicle includes an automated driving controller that is instructed to determine a hyper-local submap based on a predefined number of consecutive aggregated filtered data point cloud scans and associated pose estimates. The automated driving controller determines an initial estimated pose by aligning a latest aggregated filtered data point cloud scan with the most recent hyper-local submap based on an iterative closest point (ICP) alignment algorithm. The automated driving controller determines a pose graph based on the most recent hyper-local submap and neighboring radar point cloud scans, and executes a multi-view non-linear ICP algorithm to adjust initial estimated poses corresponding to the neighboring radar point cloud scans in a moving window fashion to determine a locally adjusted pose.
