Abstract: In one example implementation, a computer-implemented method includes receiving, by a host processing device, timestamps from a vehicle processing system of a target vehicle, the timestamps being determined based at least in part on parking area data for a target parking area and vehicle data for the target vehicle. The method further includes calculating, by the host processing device, an arrival rate and a service rate based on the timestamps. The method further includes calculating, by the host processing device, a probability of parking availability for the target parking area based at least in part on the arrival rate and the service rate. The method further includes controlling, by the host processing device, the vehicle based at least in part on the probability of parking availability for the target parking area.

Abstract: A vehicle, operating system of a vehicle and a method of operating a vehicle is disclosed. A local electronic control unit is operated at the vehicle in order to control the vehicle. A backup electronic control unit is operated at a remote computing platform for control of the vehicle. A control of the vehicle is transferred from the local electronic control unit to the backup electronic control unit upon occurrence of a fault at the local electronic control unit.

Abstract: A method for vehicle tracking and localization includes receiving, by a controller, odometry data from a sensor of the first vehicle; geospatial data from a Global Positioning System (GPS) device of the first vehicle; inertial data from an inertial measurement unit (IMU) of the first vehicle; estimating an estimated-current location of the first vehicle and an estimated-current trajectory of the first vehicle using the odometry data from the sensor, the geospatial data from the GPS device, and the inertial data from the IMU of the first vehicle; inputting the inertial data into a Bayesian Network to determine a predicted location of the first vehicle and a predicted trajectory of the first vehicle, and updating the Bayesian Network using the estimated-current location and the estimated-current trajectory of the first vehicle using the odometry data and the geospatial data.

Abstract: A system for correcting HD map images is provided. The system is configured to: receive, from a plurality of vehicles, ground view image data of a map anomaly hotspot captured by the vehicles; convert the ground view image data to bird view image data using homography; remove outliers from the bird view image data; apply an error reduction algorithm; stitch together a sequence of consecutive images from the image data after error reduction to produce a high-definition image, wherein each of the consecutive images has been generated through converting ground view image data to bird view image data using homography, removing outliers from the bird view image data, and applying an error reduction algorithm; compare the stitched sequence of consecutive images to a high-definition image of the hotspot to determine revisions to the high-definition image; and provide revised high-definition image data for use in navigating near the map anomaly hotspot.

Abstract: A system and method for object detection and classification includes receiving by a controller a first data of a scene, wherein the data reflects the scene at a first time, and performing a first classification of at least one object within the scene based on the data. The method includes determining a projected location of the at least one object corresponding to an estimated location at a second time. The method includes receiving a second data of the scene reflecting the scene at the second time. The method includes determining whether the projected location of the object corresponds to the location of the object as reflected by the second data. The method includes determining whether performing a second classification of the object is necessary based on the determination of whether the projected location corresponds to the location of the object reflected by the second data.
