  • Autonomous Vehicle Steering Juke Event Detector

  • US Patent:
    20220194469, Jun 23, 2022
  • Filed:
    Dec 17, 2020
  • Appl. No.:
    17/125484
  • Inventors:
    - Pittsburgh PA, US
    Scott Julian Varnhagen - Ann Arbor MI, US
  • International Classification:
    B62D 15/02
    B60W 60/00
  • Abstract:
    Systems and methods for determining one or more juke events are provided. The method includes generating, for an initial trajectory cycle, an initial planned trajectory of an autonomous vehicle, using a motion planning module, and generating, for a subsequent trajectory cycle, a subsequent planned trajectory of the autonomous vehicle, using the motion planning module. Each of the initial planned trajectory and the subsequent planned trajectory includes a series of planned steering wheel angles over a period of time and a steering wheel angle rate of change over the period of time. The method further includes identifying one or more first juke event qualifiers and one or more second juke event qualifiers, and identifying one or more juke events, wherein each juke event correlates to a time interval at which a first juke event qualifier and a second juke event qualifier occur within a threshold length of time from each other.

  • US Patent:
    20230115758, Apr 13, 2023
  • Filed:
    Oct 11, 2021
  • Appl. No.:
    17/498358
  • Inventors:
    - Pittsburgh PA, US
    Scott Julian Varnhagen - Ann Arbor MI, US
    Ramadev Burigsay Hukkeri - Pittsburgh PA, US
  • International Classification:
    B60W 30/14
    B60W 60/00
    B60W 40/105
    B60W 50/00
    G06N 20/00
  • Abstract:
    Systems and methods for generating a trajectory of a vehicle are disclosed. The methods include generating a spatial domain speed profile for a path represented as a sequence of poses of a vehicle between a first point and a second point. Generation of the spatial domain speed profile uses a longitudinal problem while excluding a derate interval on the path when speed of the vehicle cannot exceed a threshold. The methods further include generating a derate profile using the spatial domain speed profile and the derate interval, and transforming the derate interval to a temporal derate interval. The temporal derate interval may include time steps at which the speed of the vehicle cannot exceed the threshold while traversing the path, and may be used as an input to the longitudinal problem for generating a trajectory of the vehicle for navigating between the first point and the second point.
  • Determining Friction Data Of A Target Vehicle

  • US Patent:
    20180222462, Aug 9, 2018
  • Filed:
    Feb 8, 2017
  • Appl. No.:
    15/427328
  • Inventors:
    - Dearborn MI, US
    Scott Varnhagen - Ann Arbor MI, US
  • Assignee:
    Ford Global Technologies, LLC - Dearborn MI
  • International Classification:
    B60T 8/1755
    B60T 8/1763
    B60T 8/171
  • Abstract:
    A computer that includes a processor and memory that stores instructions executable by the processor. The instructions may include generating, at a host vehicle, a roadway friction map by: detecting a velocity change of a target vehicle; calculating friction data based on the velocity change; and storing the friction data.
  • Tracking Objects Within A Dynamic Environment For Improved Localization

  • US Patent:
    20170217433, Aug 3, 2017
  • Filed:
    Jan 29, 2016
  • Appl. No.:
    15/010303
  • Inventors:
    - Dearborn MI, US
    Scott Varnhagen - Ann Arbor MI, US
  • International Classification:
    B60W 30/12
    B60W 40/06
  • Abstract:
    The present invention extends to methods, systems, and computer program products for tracking objects within a dynamic environment for improved localization. Sensing devices are utilized to gather data about a vehicle's environment. In cases where the sensor data has become degraded, such as data indicating that lane lines have become degraded, obscured, or nonexistent, the vehicle computer system uses previously detected sensor data to estimate the speed and direction of travel of moving objects. The computer system then estimates the location of the moving objects after a specified period of time based on the estimated speed and direction of the moving object. The computer system utilizes this information to localize the vehicle within the dynamic environment and to control the configuration of the vehicle.
