  • 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.
