Patent number: 11881028Abstract: A vehicle system includes a lidar system that obtains an initial point cloud and obtains a dual density point cloud by implementing a first neural network and based on the initial point cloud. The dual density point cloud results from reducing point density of the initial point cloud outside a region of interest (ROI). Processing the dual density point cloud results in a detection result that indicates any objects in a field of view (FOV) of the lidar system. A controller obtains the detection result from the lidar system and controls an operation of the vehicle based on the detection result.Type: GrantFiled: May 4, 2021Date of Patent: January 23, 2024Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Shuqing Zeng, Jordan Chipka, Yasen Hu

Patent number: 11479148Abstract: A system and method for personalization of adjustable features of a vehicle. The system includes a processor and an actuator. The processor detectors key points of a person from a two-dimensional image and predicts a pose of the person. The processor translates a respective position of the key points from a two-dimensional coordinate system to a three-dimensional coordinate system based in part on the pose and measurements of distances between the key points. The processor determines a baseline configuration of an adjustable feature of the vehicle based in part on measurements between the key points in the three-dimensional coordinate system. The processor causes an actuator to adjust the adjustable feature to conform to the baseline configuration.Type: GrantFiled: August 8, 2019Date of Patent: October 25, 2022Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Yasen Hu, Kausalya Singuru, Shiming Duan, Yao Hu, Nicholas W.

Publication number: 20220227358Abstract: A vehicle control system for automated driver-assistance includes a controller that generates a control signal to alter operation of one or more actuators of a vehicle based on a heading of a target. Generating the control signal includes determining a first heading of the target based on sensor data. Further, a probability (pa) of the first heading being accurate is computed based on a number of heading flips encountered in a duration-window of a predetermined length. Further, a map-probability (pm) that the target is traveling according to data from a navigation map is computed. Further, a posterior probability (pf) of the first heading being accurate is computed based on the probability (pa) and the map-probability (pm). Generating the control signal further includes, in response to the posterior probability being less than a predetermined threshold, correcting the first heading, and generating the control signal based on the first heading.Type: ApplicationFiled: January 20, 2021Publication date: July 21, 2022Inventors: Yasen Hu, Brent N.

Patent number: 10817728Abstract: A method of updating an identification algorithm of a vehicle includes sensing an image and drawing boundary boxes in the image. The algorithm attempts to identify an object-of-interest within each respective boundary box. The algorithm also attempts to identify a component of the object-of-interest within each respective boundary box, and if component is identified, calculates an excluded amount of a component boundary that is outside an object boundary. When the excluded amount is greater than a coverage threshold, the algorithm communicates the image to a processing center, which may identify a previously un-identified the object-of-interest in the image. The processing center may add the image to a training set of images to define a revised training set of images, and retrain the identification algorithm using the revised training set of images. The updated identification algorithm may then be uploaded onto the vehicle.Type: GrantFiled: January 23, 2019Date of Patent: October 27, 2020Assignee: GM Global Technology Operations LLCInventors: Syed B.
