Abstract: A module for a leader vehicle of a convoy can have a suite of sensors, a communication system, and a controller. The sensor suite can have at least one feature sensor that detects features and/or terrain in an environment and at least one location sensor that determines a location of the leader vehicle. Via the sensor suite, the controller can detect features as the leader vehicle travels along a route through the environment as well as the route of the leader vehicle. The controller can build a map for at least part of the environment with the detected route therethrough. Data indicative of the map and the detected route can then be transmitted to one or more follower vehicles. In some embodiments, the leader vehicle is manually driven while the follower vehicles operate autonomously.

Abstract: A scene creation system for an autonomous vehicle includes one or more controllers executing instructions to receive perception data and map data of a roadway the autonomous vehicle is traveling along, and identify a plurality of lane segments of the roadway that the autonomous vehicle travels along based on the perception data and the map data. The one or more controllers connect the plurality of lane segments together based on a spatial relationship between the plurality of lane segments to create a lane graph. The one or more controllers classify each of the plurality of lane segments of the lane graph to one or more lane attributes and reassemble the plurality of lane segments to create a representation of the roadway. The one or more controllers recreate a scene of an environment surrounding the autonomous vehicle based on the representation of the lanes that are part of the roadway.

Abstract: An object of the present invention is to determine a difference on a map by using an exterior environment recognition sensor of a traveling vehicle and host vehicle position estimation information on the basis of existing map information and to enable the difference to be transmitted to a map server. According to the present invention, there is provided an in-vehicle map information correction device that corrects map information, the map information correction device including: a map holding unit (102) that holds the map information; a position estimation unit (104) that estimates position information on a vehicle; at least one of a lane change information acquisition unit (106) that acquires lane change information indicating whether or not the vehicle has changed a lane and a dividing line information acquisition unit (105) that acquires information on a dividing line type of a road on which the vehicle is traveling; and a difference determination unit (103) that generates correction information for correcting the map information based on at least one of the position information, the lane change information, and the information on the dividing line type.

Abstract: A method for training a model to detect lane markings. The method includes: providing images that are specific to a recording by at least one sensor of a vehicle, and in which the lane markings are mapped; providing ground truth data specific to a geometry of the lane markings in the provided images; training the model on the basis of the provided images and ground truth data for a three-dimensional modeling of the geometry of the lane markings based on a parameterization of a continuous curve.

Abstract: The subject disclosure relates to techniques for optimizing autonomous vehicle activities at a fleet level. A process of the disclosed technology can include measuring a first set of cost metrics for a first plurality of autonomous vehicles (AVs) associated with a first vehicle routing version, wherein the first set of cost metrics comprises energy consumption values for two or more of the first plurality of AVs, measuring a second set of cost metrics for a second plurality of AVs associated with a second vehicle routing version, wherein the second set of cost metrics comprises energy consumption values for two or more of the second plurality of AVs, and comparing the first set of cost metrics with the second set of cost metrics to determine routing updates configured to reduce fleetwide energy consumption.

Abstract: Described herein are various technologies that pertain to controlling an AV based upon forward-looking observations of road surface behavior. With more specificity, technologies described herein pertain to controlling maneuvering of an AV in a region of a driving environment based upon an observed acceleration of an object in that region of the driving environment. A plurality of positions of an object in the driving environment are determined from output of sensors mounted on the AV. An acceleration of the object is computed based upon the positions. The AV is subsequently controlled based upon the computed acceleration.

Abstract: An approach is provided for verifying reported ramp closures. The approach involves, for example, processing a ramp closure report to determine reported ramp link(s) associated with the ramp closure report. The approach also involves constructing a ramp network comprising the reported ramp link(s) and other ramp link(s) connected to the reported ramp link(s). The approach further involves collecting probe data collected from one or more sensors of one or more vehicles traveling within the ramp network. The approach further involves identifying one or more driving patterns based on one or more vehicle paths determined from the probe data. The approach further involves performing a verification of a closure status of the reported ramp link(s) based on the one or more driving patterns. The approach further involves providing the verification of the closure status as an output.
