  • Publication number: 20200167934
    Abstract: Methods and systems for enhanced object tracking by receiving sensor fusion data related to target objects and object tracks; determining splines representing trajectories of each target object; filtering the sensor fusion data about each target object based on a first, second and third filtering model wherein each filtering model corresponds to one or more of a set of hypotheses used for processing vectors related to trajectories of a track object wherein the set of hypotheses comprise: a path constraint, a path unconstrained, and a stationary hypothesis; and generating a hypothesis probability for determining whether to use a particular hypothesis based wherein the hypothesis probability is determined based on results from the first, second and third filtering models and from results from classifying, by at least one classification model, one or more features related to the object track for the target object.

  • Publication number: 20200149896
    Abstract: A method for autonomous vehicle map construction includes automatically capturing location data, movement data, and perception data from a vehicle that has traveled down a road, wherein the perception data includes data that identifies the location of lane edges and lane markers for the road, the location of traffic signs associated with the road, and the location of traffic signaling devices for the road. The method further includes pre-processing to associate the captured perception data with the captured location data, captured movement data, and navigation map data; determining, from the pre-processed data, lane boundary data, traffic device and sign location data, and lane level intersection data that connects the intersecting and adjoining lanes identified through the lane boundary data; and storing the lane boundary data, traffic device and sign location data, and lane level intersection data in a map file configured for use by an autonomous vehicle.

  • Publication number: 20200142026
    Abstract: A disambiguating system for disambiguating between ambiguous detections is provided. The system includes a plurality of modules, wherein each module is configured to disambiguate between ambiguous detections by selecting, as a true detection, one candidate detection in a set of ambiguous detections and wherein each module is configured to apply a different selection technique. The system includes: one or more modules configured to select as the true detection, the candidate detection whose associated position is closer to a position indicated by other data and one or more modules configured to select as the true detection, the candidate detection with the highest probability of being true based on other sensor data.

  • Publication number: 20190354781
    Abstract: A system and method for determining an object location by using map information is disclosed. The method includes receiving, by a controller, an image data of a scene. An object is located within the scene. The method also includes determining, by the controller, a location of the object based on the image data of the scene. The method can also include receiving, by the controller, a map information. The map information includes at least one path information. The method also includes determining an association between the location of the object based on the image data and the map information of the scene. The method also includes determining a 3-dimensional location of the object based on the determined association.

  • Publication number: 20190337451
    Abstract: Technical solutions are described herein for providing driver notification in a vehicle. An example system includes one or more sensors that measure one or more attributes of a remote object in a predetermined vicinity of the vehicle. The system further includes an output device that provides a notification to a driver. The system further includes a remote object monitoring system that generates a driver notification to be provided via the output device based on the attributes of the remote object. Generating the driver notification includes determining a recklessness score for the remote object based on the attributes of the remote object. Generating the driver notification further includes, in response to the recklessness score exceeding a predetermined threshold, generating the driver notification that comprises a directional information that provides a spatial awareness of a location of the remote object in relation to the vehicle.

  • Patent number: 10442443
    Abstract: Technical solutions are described for providing a driver performance feedback to a driver of a vehicle. An example method includes receiving, by a controller, a first maneuver control from an automated driving system of the vehicle. The method further includes receiving, by the controller, a second maneuver control from the driver. The method further includes, in response to the first maneuver control being different from the second maneuver control, generating a driver notification that is indicative of the first maneuver control from the automated driving system, and operating the vehicle using the second maneuver control.

  • Patent number: 10399492
    Abstract: Technical solutions are described herein for adjusting a notification system of a vehicle. An example method includes receiving, by a controller, an occupant profile of an occupant of the vehicle. The method further includes adjusting, by the controller, a haptic array according to the occupant profile, the haptic array comprising a plurality of haptic actuators, the adjusting comprising activating a first subset of the haptic actuators and deactivating a second subset of the haptic actuators. Further, the method includes providing, by the haptic array, a notification to the occupant of the vehicle by providing a haptic feedback using the activated haptic actuators.

  • Publication number: 20190106085
    Abstract: Methods and apparatus are provided for cleaning a sensor lens cover for an optical vehicle sensor. The method includes monitoring the sensor lens cover for a contaminant obstructing at least a portion of the sensor lens cover and determining the presence of the commandant and a contaminant type using information provided by one or more vehicle sensors. A cleaning modality selected based the contaminant type is activated and it is determined whether the cleaning modality has removed the contaminant from the sensor lens cover.
