摘要： 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.

摘要： A system for dynamically calculating collision avoidance metric thresholds for a vehicle includes a vehicle sensor, a passenger position tracking device, and a controller. The controller is in electrical communication with the vehicle sensor and the passenger position tracking device. The controller is programmed to determine a collision avoidance metric using the vehicle sensor, determine an offset to a collision avoidance metric threshold using the passenger position tracking device, and adjust the collision avoidance metric threshold based on the offset. The controller is also programed to compare the collision avoidance metric to the collision avoidance metric threshold and perform an action in response to determining that the collision avoidance metric is less than or equal to the collision avoidance metric threshold.

摘要： A method for validating an autonomous vehicle performance using nearby traffic patterns includes receiving remote vehicle data. The remote vehicle data includes at least one remote-vehicle motion parameter about a movement of a plurality of remote vehicles during a predetermined time interval. The method further includes determining a traffic pattern of the plurality of remote vehicles using the at least one remote-vehicle motion parameter. The method includes determining a similarity between the traffic pattern of the plurality of remote vehicles and movements of the host vehicle. Further, the method includes determining whether the similarity between the traffic pattern of the plurality of remote vehicles and movements of the host vehicle is less than a predetermined threshold. Also, the method includes commanding the host vehicle to adjust the movements thereof to match the traffic pattern of the plurality of remote vehicles.

摘要： A method for lane centering control of a host vehicle that is towing a trailer includes: determining in real time, by a controller of the host vehicle, a radius of curvature of a turn, wherein the host vehicle is approaching the turn; determining, by the controller, a trailer required offset based on the radius of the curvature of the turn to maintain the host vehicle and the trailer in a lane while the host vehicle and the trailer move along the turn; and controlling the host vehicle using the trailer offset to maintain the host vehicle and the trailer in a lane while the host vehicle and the trailer move along the turn. The method also allows the host vehicle to avoid encroaching vehicles.

摘要： A system and method of manufacturing an aluminum fuel cell cradle includes providing a negative cast mold having cavities to form the cradle and providing a feeding mechanism disposed about the mold and in fluid communication with the cavities thereof. The feeding mechanism includes a plurality of primary risers connected to and in fluid communication with cavities. The method further includes melting a first metallic material to define a molten metallic material, and moving the mold to a vertical casting orientation about a rotational axis, while feeding molten metallic material through the runner to the cavities, and cooling the molten metallic material to define a solidified metallic material. A second solidification time in the risers is greater than a first solidification time in the mold such that shrinkage of the solidified metallic material occurs in the risers away from the mold.

摘要： A quality control system analyzes the quality of a battery cell, with the battery cell defining a gas pouch configured to expand from a deflated configuration to an inflated configuration when filled with a gas formed during a cell formation process. The system comprises a computational system comprising a processor and a memory and a measurement instrument in electronic communication with the computational system. The measurement instrument is arranged to measure a distance defined by the gas pouch and transmit a signal to the computational system corresponding to the distance. The computational system is arranged to analyze the distance with the processor and determine a volumetric measurement of the gas within the gas pouch and compare the volumetric measurement to a threshold in the memory to assess a quality score for the battery cell. A corresponding method analyzes the quality of the battery cell with the quality control system.
