Abstract
A system to use submaps to control operation of a vehicle is disclosed. A storage system may be provided with a vehicle to store a collection of submaps that represent a geographic area where the vehicle may be driven. A programmatic interface may be provided to receive submaps and submap updates independently of other submaps.
Claims24
A method for operating a vehicle, the method being implemented by one or more or more processors of the vehicle and comprising:
- retrieving, from a storage medium, a series of submaps from a collection of submaps, each submap of the collection representing an area of a road network for a geographic region;
- wherein each submap of the collection is provided (i) an identifier from the collection, (ii) multiple data layers, each data layer representing a feature set of the area of the road network of that submap, and (iii) a connector data set to link the submap with another submap that represents an adjacent area to the area of the road network of that submap;
- and
- autonomously controlling the vehicle using submaps retrieved from the storage medium.
