Abstract: Techniques are described for operating a vehicle using sensor data provided by one or more ultrasonic sensors located on or in the vehicle. An example method includes receiving, by a computer located in a vehicle, data from an ultrasonic sensor located on the vehicle, where the data includes a first set of coordinates of two points associated with a location where an object is detected by the ultrasonic sensor; determining a second set of coordinates associated with a point in between the two points; performing a first determination that the second set of coordinates is associated with a lane or a road on which the vehicle is operating; performing a second determination that the object is movable; and sending, in response to the first determination and the second determination, a message that causes the vehicle to perform a driving related operation while the vehicle is operating on the road.

Abstract: The present disclosure provides methods and systems of sampling-based object pose determination. An example method includes obtaining, for a time frame, sensor data of the object acquired by a plurality of sensors; generating a two-dimensional bounding box of the object in a projection plane based on the sensor data of the time frame; generating a three-dimensional pose model of the object based on the sensor data of the time frame and a model reconstruction algorithm; generating, based on the sensor data, the pose model, and multiple sampling techniques, a plurality of pose hypotheses of the object corresponding to the time frame, generating a hypothesis projection of the object for each of the pose hypotheses by projecting the pose hypothesis onto the projection plane; determining evaluation results by comparing the hypothesis projections with the bounding box; and determining, based on the evaluation results, an object pose for the time frame.

Abstract: A computer-implemented method and apparatus are provided for training a safety driver associated with an autonomous vehicle (AV) operating in an autonomous driving mode. The computer-implemented method includes receiving a selection of one or more vehicle operation faults that are configured to impact operation of one or more vehicle systems of the AV. The computer-implemented method also includes injecting the one or more vehicle operation faults into one or more vehicle systems of the AV and detecting one or more driver responses executed by the safety driver in response to the one or more vehicle operation faults. The computer-implemented method further includes determining a reaction time associated with the one or more driver responses. The reaction time is a measure of time it takes the safety driver to respond to the one or more vehicle operation faults.

Abstract: Image processing techniques are described to obtain an image from a camera located on a vehicle while the vehicle is being driven, cropping a portion of the obtained image corresponding to a region of interest, detecting an object in the cropped portion, adding a bounding box around the detected object, determining position(s) of reference point(s) on the bounding box, and determining a location of the detected object in a spatial region where the vehicle is being driven based on the determined one or more positions of the second set of one or more reference points on the bounding box.

Abstract: An example method of controlling a vehicle using a multi-node computational architecture includes receiving, by a first computational node, waypoints and vehicle states, and generating a first control command set for motion of the vehicle in a lateral direction with a first complexity and a second control command set for motion in a longitudinal direction with a second complexity that is less than the first complexity. A second computational node, operating in parallel with the first computational node, is used to generate a third control command set for motion in the longitudinal direction with the first complexity. The method further includes selecting, by a control arbitrator and based on the vehicle states and health status indications of the first and second computational nodes, either the second control command set or the third control command set, and outputting the selected control command set, which is used to control the vehicle.
