1. A system for controlling navigation of a vehicle, comprising:
- one or more processors; and
one or more memory resources storing instructions that, when executed by the one or more processors, cause the system to;
for a set of path segments within a geographic region in which the vehicle is operating, determine a risk value for each respective path segment of the set of path segments based on a plurality of risk factors associated with autonomous operation of the vehicle along the respective path segment;
based on the determined risk value for each respective path segment of the set of path segments, combine a plurality of path segments from the set of path segments to generate a travel route for the vehicle from a first location to a second location; and
autonomously control the vehicle to navigate along the travel route;
wherein the determined risk value for each respective path segment of the set of path segments represents a cost layer in a corresponding map utilized by the vehicle for autonomous operation along the respective path segment, and wherein the system generates the travel route based on a sum of the determined risk values for the plurality of path segments.

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.

12. A method of controlling navigation of a vehicle, the method being implemented by one or more processors and comprising:
-
for a set of path segments within a geographic region in which the vehicle is operating, determining a risk value for each respective path segment of the set of path segments based on a plurality of risk factors associated with autonomous operation of the vehicle along the respective path segment; based on the determined risk value for each respective path segment of the set of path segments, combining a plurality of path segments from the set of path segments to generate a travel route for the vehicle from a first location to a second location; and autonomously controlling the vehicle to navigate along the travel route; wherein the determined risk value for each respective path segment of the set of path segments represents a cost layer in a corresponding map utilized by the vehicle for autonomous operation along the respective path segment, and wherein the one or more processors generate the travel route based on a sum of the determined risk values for the plurality of path segments. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A vehicle comprising:
-
a plurality of sensors that generate sensor data to determine a plurality of risk factors associated with autonomous operation of the vehicle; one or more processors; and one or more memory resources storing instructions that, when executed by the one or more processors, cause the vehicle to; for a set of path segments within a geographic region in which the vehicle is operating, determine a risk value for each respective path segment of the set of path segments based on a plurality of risk factors associated with autonomous operation of the vehicle along the respective path segment; based on the determined risk value for each respective path segment of the set of path segments, combine a plurality of the path segments to generate a travel route for the vehicle from a first location to a second location; and autonomously control the vehicle to navigate along the travel route; wherein the determined risk value for each respective path segment of the set of path segments represents a cost layer in a corresponding map utilized by the vehicle for autonomous operation along the respective path segment, and wherein the vehicle generates the travel route based on a sum of the determined risk values for the plurality of path segments.
