  • Publication number: 20190146509
    Abstract: A system and method for autonomous vehicle routing using annotated maps. For at least some path segments within a geographic region in which the vehicle is operating, values are determined for the path segments based at least on risk factors associated with autonomous operation of the vehicle along each path segment. Path segments are combined to generate a travel route, from a first location to a second location, based on the determined values, and the vehicle is controlled to navigate along the travel route.

  • Publication number: 20180328745
    Abstract: Systems and methods can generate and/or implement coverage plans for vehicle navigation. Such coverage plans can be descriptive of a travel route for a vehicle to navigate a set of travel way portions within a map of a geographic area. The coverage plan can include a travel route that traverses each travel way portion at least once while reducing total travel cost (e.g., defined by a travel distance, number and/or types of turns, etc.) over all travel way portions. The coverage plan can also reduce turn angles and/or eliminate u-turns in order to provide a coverage plan that is safer and easier for implementation by vehicles controlled to navigate along the travel route.

  • Publication number: 20180061242
    Abstract: A hybrid trip planning system can receive transport requests from requesting users, determine pick-up and/or drop off locations from the transport request, and select available autonomous vehicles (AV) to service the transport requests. For each transport request, the planning system can identify a plurality of entry points from the pick-up location to an autonomy grid on which the AVs operate, and a plurality of exit points from the autonomy grid to the drop-off location. The planning system may determine optimal entry and/or exit points and transmit transport data to the selected AV. The transport data can provide optimal routing for a human safety driver to drive the selected AV in manual segments that are off grid, and switch the AV into an autonomous driving mode within the autonomy grid.
