Abstract: A system for vehicle navigation may include a processor including a circuitry and a memory. The memory may include instructions that when executed by the circuitry cause the processor to receive navigational information associated with the vehicle including an indicator of a location of the vehicle, and determine target navigational map segments to retrieve from a map database. The map database may include stored navigational map segments each corresponding to a real-world area. The determination of the target navigational map segments may be based on the indicator of vehicle location and on map segment connectivity information associated with the stored navigational map segments. The instructions may also cause the processor to initiate downloading of the target navigational map segments from the map database, and cause the vehicle to navigate along a target trajectory included in one or more of the target navigational map segments downloaded from the map database.

Abstract: A system for navigating a host vehicle includes at least one electronic horizon processor to access a map representative of at least a road segment on which the host vehicle travels or is expected to travel, wherein the map includes one or more splines representative of road features associated with the road segment, localize the host vehicle relative to a drivable path for the host vehicle represented among the one or more splines, determine a set of points associated with the one or more splines based on the localization of the host vehicle relative to the drivable path for the host vehicle, and generate a navigation information packet including information associated with the one or more splines and the determined set of points relative to the one or more splines.

Abstract: Systems and methods for automatically generating a navigational map relative to one or more road segments are disclosed. In one implementation at least one processor is programmed to cause collection of first navigational information associated with a first density level; determine, based on sensors of the host vehicle, a location of the host vehicle; determine whether the location is at or within a predetermined distance from a geographical region of interest; cause, based on a determination that the location is at or within the predetermined distance from the geographical region of interest, collection of second navigational information associated with a second density level higher than the first density level; upload from the host vehicle at least one of the collected first or second navigational information; and update the navigational map based on the uploaded first or second navigational information.

Abstract: Systems and methods for providing one or more map segments to one or more vehicles are disclosed. In one implementation at least one processor is programmed to receive navigational information from a vehicle, the navigational information including an indicator of a location of the vehicle, an indicator of a speed of the vehicle, and an indicator of a direction of travel of the vehicle; analyze the received navigational information and determine a potential travel envelope for the vehicle; and send to the vehicle one or more map segments including map information for a geographical region at least partially overlapping with the potential travel envelope of the vehicle.
