Patent number: 10606259Abstract: A method for autonomously operating a driverless vehicle along a path between a first geographic location and a destination may include receiving communication signals from the driverless vehicle. The communication signals may include sensor data from the driverless vehicle and data indicating occurrence of an event associated with the path. The communication signals may also include data indicating that a confidence level associated with the path is less than a threshold confidence level due to the event. The method may also include determining, via a teleoperations system, a level of guidance to provide the driverless vehicle based on data associated with the communication signals, and transmitting teleoperations signals to the driverless vehicle. The teleoperations signals may include guidance to operate the driverless vehicle according to the determined level of guidance, so that a vehicle controller maneuvers the driverless vehicle to avoid, travel around, or pass through the event.Type: GrantFiled: July 7, 2017Date of Patent: March 31, 2020Assignee: Zoox, Inc.Inventors: Amanda Lee Kelly Lockwood, Ravi Gogna, Gary Linscott, Timothy Caldwell, Marin Kobilarov, Paul Orecchio, Dan Xie, Ashutosh Gajanan Rege, Jesse Sol Levinson

Patent number: 10591910Abstract: A system, an apparatus or a process may be configured to implement an application that applies artificial intelligence and/or machine-learning techniques to predict an optimal course of action (or a subset of courses of action) for an autonomous vehicle system (e.g., one or more of a planner of an autonomous vehicle, a simulator, or a teleoperator) to undertake based on suboptimal autonomous vehicle performance and/or changes in detected sensor data (e.g., new buildings, landmarks, potholes, etc.). The application may determine a subset of trajectories based on a number of decisions and interactions when resolving an anomaly due to an event or condition. The application may use aggregated sensor data from multiple autonomous vehicles to assist in identifying events or conditions that might affect travel (e.g., using semantic scene classification). An optimal subset of trajectories may be formed based on recommendations responsive to semantic changes (e.g., road construction).Type: GrantFiled: May 14, 2018Date of Patent: March 17, 2020Assignee: Zoox, Inc.Inventors: Jesse Sol Levinson, Gabriel Thurston Sibley, Ashutosh Gajanan Rege

Patent number: 10504282Abstract: Techniques for generating maps without shadows are discussed herein. A plurality of images can be captured by a vehicle traversing an environment representing various perspectives and/or lighting conditions in the environment. A shadow within an image can be identified by a machine learning algorithm trained to detect shadows in images and/or by projecting the image onto a three-dimensional (3D) map of the environment and identifying candidate shadow regions based on the geometry of the 3D map and the location of the light source. Shadows can be removed or minimized by utilizing blending or duplicating techniques. Color information and reflectance information can be added to the 3D map to generate a textured 3D map. A textured 3D map without shadows can be used to simulate the environment under different lighting conditions.Type: GrantFiled: March 21, 2018Date of Patent: December 10, 2019Assignee: Zoox, Inc.Inventors: Jesse Sol Levinson, Ashutosh Gajanan Rege, Brice Rebsamen, Elena Stumm, Nitesh Shroff, Derek Adams

Publication number: 20190278292Abstract: Techniques for decimating portions of a map of an environment are discussed herein. The environment can be represented by a three-dimensional (3D) map including a plurality of polygons and semantic information associated with the polygons. In some cases, decimation operations may be based on semantic information associated with the environment. Differing decimation operations and/or levels may be applied to polygons of different semantic classifications or differing contribution levels. Boundaries between regions having different semantic information can be preserved. Meshes can be decimated using different decimation operators or decimation levels and an accuracy of localizing can be compared using the various decimated meshes. An optimal mesh can be selected and sent to vehicles for localizing the vehicles in the environment.Type: ApplicationFiled: March 6, 2018Publication date: September 12, 2019Inventors: Jesse Sol Levinson, Ashutosh Gajanan Rege, Brice Rebsamen, Elena Stumm, Nitesh Shroff, Derek Adams

Patent number: 10353390Abstract: Techniques for generating and executing trajectories to guide autonomous vehicles are described. In an example, a first computer system associated with an autonomous vehicle can generate, at a first operational frequency, a route to guide the autonomous vehicle from a current location to a target location. The first computer system can further determine, at a second operational frequency, an instruction for guiding the autonomous vehicle along the route and can generate, at a third operational frequency, a trajectory based at least partly on the instruction and real-time processed sensor data. A second computer system that is associated with the autonomous vehicle and is in communication with the first computer system can execute, at a fourth operational frequency, the trajectory to cause the autonomous vehicle to travel along the route. The separation of the first computer system and the second computer system can provide enhanced safety, redundancy, and optimization.Type: GrantFiled: June 23, 2017Date of Patent: July 16, 2019Assignee: Zoox, Inc.Inventors: Gary Linscott, Robert Edward Somers, Joona Markus Petteri Kiiski, Marin Kobilarov, Timothy Caldwell, Jacob Lee Askeland, Ashutosh Gajanan Rege, Joseph Funke
