Patent number: 11780464Abstract: Techniques are described herein for generating trajectories for autonomous vehicles using velocity-based steering limits. A planning component of an autonomous vehicle can receive steering limits determined based on safety requirements and/or kinematic models of the vehicle. Discontinuous and discrete steering limit values may be converted into a continuous steering limit function for use during on-vehicle trajectory generation and/or optimization operations. When the vehicle is traversing a driving environment, the planning component may use steering limit functions to determine a set of situation-specific steering limits associated with the particular vehicle state and/or driving conditions. The planning component may execute loss functions, including steering angle and/or steering rate costs, to determine a vehicle trajectory based on the steering limits applicable to the current vehicle state.Type: GrantFiled: December 17, 2021Date of Patent: October 10, 2023Assignee: Zoox, Inc.Inventors: Joseph Funke, Steven Cheng Qian, Kazuhide Okamoto, Jacob Patrick Thalman, Sriram Narayanan, Liam Gallagher

Patent number: 11776135Abstract: Techniques are discussed for determining a velocity of an object in an environment from a sequence of images (e.g., two or more). A first image of the sequence is transformed to align the object with an image center. Additional images in the sequence are transformed by the same amount to form a sequence of transformed images. Such sequence is input into a machine learned model trained to output a scaled velocity of the object (a relative object velocity (ROV)) according to the transformed coordinate system. The ROV is then converted to the camera coordinate system by applying an inverse of the transformation. Using a depth associated with the object and the ROV of the object in the camera coordinate frame, an actual velocity of the object in the environment is determined relative to the camera.Type: GrantFiled: November 3, 2020Date of Patent: October 3, 2023Assignee: Zoox, Inc.Inventors: Vasiliy Karasev, Sarah Tariq

Patent number: 11774979Abstract: Techniques are discussed for determining a data level for portions of data for processing. In some cases, a data level can correspond to a resolution level, a compression level, a bit rate, and the like. In the context of image data, the techniques can determine a region of first image data to be processed a high resolution and a region of second image data to be processed at a low resolution. The regions can be determined by a machine learned algorithm that is trained to output identifications of such regions. Training data may be determined by identifying differences in outputs based on the first and second image data. The image data associated with the determined regions and the determined resolutions can be processed to perform object detection, classification, segmentation, bounding box generation, and the like, thereby conserving processing, bandwidth, and/or memory resources in real time systems.Type: GrantFiled: September 23, 2022Date of Patent: October 3, 2023Assignee: Zoox, Inc.Inventor: Jesse Sol Levinson

Patent number: 11772643Abstract: A vehicle computing system may implement techniques to determine relevance of objects detected in an environment to a vehicle operating in the environment (e.g., whether an object could potentially impact the vehicle's ability to safely travel). The techniques may include determining an initial location and trajectory associated with a detected object and determining whether the detected object may intersect a path polygon (e.g., planned path with a safety buffer) of the vehicle. A path intersection may include the detected object intersecting the path polygon or sharing a road segment with the vehicle at a substantially similar height as the vehicle (e.g., on a similar plane). Based on a determination that the detected object does not intersect the planned path of the vehicle, the vehicle computing system may determine that the detected object is irrelevant to the vehicle and may disregard the detected object in vehicle control planning considerations.Type: GrantFiled: May 20, 2019Date of Patent: October 3, 2023Assignee: Zoox, Inc.Inventors: Jefferson Bradfield Packer, Lichao Ma

Patent number: 11776400Abstract: Junction queueing for vehicles is described, in which vehicles may be queued based on arrival time at a junction, position relative to a stopping location at the junction, and/or an amount of time waiting for other vehicles to proceed through the junction (timeout). In some examples, the queue may be first generated based on the arrival times of any other vehicle relative to a particular vehicle generating the queue. The queue may be updated based on arrival times of other vehicles (e.g., after the particular vehicle), whether another vehicle has proceeded out-of-turn (e.g., based on a position at the junction), and/or a timeout for vehicles that wait for others to yield at the junction. In some examples, hysteresis and alterations of the score for safety reasons may alter queue order. The queue may be used to control the particular vehicle to traverse the junction.Type: GrantFiled: November 12, 2021Date of Patent: October 3, 2023Assignee: Zoox, Inc.Inventors: Moritz Harmel, William Anthony Silva

Patent number: 11772535Abstract: A system and method for determining whether a passenger is seated in a seating area and, based at least in part on detecting the passenger, engaging or disengaging a flap in a headrest. Such a headrest may span multiple seats so that a single headrest is used by multiple passengers. Each of one or more flaps in the single headrest may then be configured by the passenger to provide each passenger with their own privacy and comfort. By actively controlling the state of the flap, a uniform passenger experience may be created so that the flap is in the same state upon a passenger entering the vehicle. Further, examples of the headrest are designed and configured to couple directly, or indirectly, to a vehicle body, such that the headrest does not couple directly to a seat or passenger seating area.Type: GrantFiled: December 28, 2020Date of Patent: October 3, 2023Assignee: Zoox, Inc.Inventors: Nahuel Elias Battaglia, Anke Christine Bodack, Felix Jacob Lorsignol, Andrew Frank Raczkowski, Herman Francisco Delos Santos, Christopher John Stoffel, Bryan Scot Thompson, Timothy David Kentley-Klay
