  • Publication number: 20200240794
    Abstract: A georeferenced trajectory system for vehicles receives trajectory data generated by a plurality of vehicle sensors and scaffolds of previously generated maps and aligns geometry data for a geographic region and trajectory data from the received data from different map builds. A scaffold of a geographic region to be mapped during an initial map build is generated, and the trajectory data from respective map builds is aligned with the scaffold of previously generated maps to generate a map of the geographic region. The resulting map expands the coverage of the existing map such that old and new map data is in a common consistent reference frame whereby the map may be built incrementally by merging or expanding local scaffolds and filling in the merged or expanded scaffold while ensuring global consistency.

  • Publication number: 20200233415
    Abstract: A method of controlling navigation of autonomous vehicles includes accessing map data descriptive of the identity and location of different travel ways within a surrounding environment of an autonomous vehicle and accessing constraint data descriptive of one or more geographic areas or geographic identifiers, within the map data, for which associated navigational constraints are defined. The constraint data includes a depart constraint that specifies an area that an autonomous vehicle may not enter but may exit if inside the area when the depart constraint is imposed, thereby preventing the autonomous vehicle from being trapped in a forbidden area even though the autonomous vehicle may safely complete its route. A travel route is determined for the autonomous vehicle based at least in part on the map data evaluated relative to the constraint data including the depart constraint, and motion of the autonomous vehicle is controlled based on the determined travel route.
