Abstract: Systems and methods are provided for vehicle navigation. In one implementation, a system for identifying objects in an environment of a host vehicle may comprise at least one processor. The processor may be programmed to receive, from an image capture device, an image representative of the environment of the host vehicle and analyze the image to detect objects represented in the image. The processor may compare position information for the objects to location information for mapped objects represented a navigational map segment to determine a first estimated position of the host vehicle. The processor may further provide the image and an identifier associated with the map segment to a trained system and receive a second estimated position of the host vehicle. The processor may determine a navigational action based on a combination of the first and second estimated positions and cause the host vehicle to implement the determined navigational action.

Abstract: A system for mapping road segment free spaces for use in autonomous vehicle navigation. The system includes at least one processor programmed to: receive from a first vehicle one or more location identifiers associated with a lateral region of free space adjacent to a road segment; update an autonomous vehicle road navigation model for the road segment to include a mapped representation of the lateral region of free space based on the received one or more location identifiers; and distribute the updated autonomous vehicle road navigation model to a plurality of autonomous vehicles.
