Real time risk assessment and operational changes with semi-autonomous vehicles
First Claim
1. A method comprising:
- receiving, by a computing device, an indication of a first travel route associated with an autonomous vehicle;
determining an autonomous route risk value comprising an indication of an accident risk associated with traversal of the first travel route by a vehicle in an autonomous driving mode;
determining a manual route risk value comprising an indication of an accident risk associated with traversal of the first travel route by a vehicle in a manual driving mode;
responsive to determining, based on a comparison of the autonomous route risk value and the manual route risk value, that the autonomous driving mode is associated with a lower risk of an accident, causing a driver of the autonomous vehicle to be notified that the autonomous driving mode is a safer mode for traversal of the first travel route; and
responsive to determining, based on a comparison of the autonomous route risk value and the manual route risk value, that the manual driving mode is associated with a lower risk of an accident, causing a driver of the autonomous vehicle to be notified that the manual driving mode is the safer mode for traversal of the first travel route.

Abstract
A route risk mitigation system and method using real-time information to improve the safety of vehicles operating in semi-autonomous or autonomous modes. The method mitigates the risks associated with driving by assigning real-time risk values to road segments and then using those real-time risk values to select less risky travel routes, including less risky travel routes for vehicles engaged in autonomous driving over the travel routes. The route risk mitigation system may receive location information, real-time operation information, (and/or other information) and provide updated associated risk values. In an embodiment, separate risk values may be determined for vehicles engaged in autonomous driving over the road segment and vehicles engaged in manual driving over the road segment.

8. A method comprising:
-
receiving, by a computing device, autonomous historical accident information of vehicles engaged in an autonomous driving mode over a first travel route; receiving manual historical accident information of vehicles engaged in a manual driving mode over the first travel route; based on the autonomous historical accident information, determining an autonomous route risk value comprising an indication of an accident risk associated with traversal of a first travel route by a vehicle in an autonomous driving mode; based on the manual historical accident information, determining a manual route risk value comprising an indication of an accident risk associated with traversal of the first travel route by a vehicle in a manual driving mode; generating a data store comprising the autonomous route risk value and the manual route risk value, wherein the autonomous route risk value and the manual route risk value are associated, in the data store, with the first travel route; receiving an indication of a planned travel route associated with an autonomous vehicle, wherein the planned travel route comprises at least the first travel route; and outputting a notification identifying one driving mode of the autonomous driving mode and the manual driving mode, wherein identifying the one driving mode is based on a comparison of the autonomous route risk value and the manual route risk value. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. An apparatus, comprising:
-
a processor configured to execute computer-executable instructions; and a memory storing the computer-executable instructions that, when executed by the processor, cause the apparatus to; receive an indication of a first travel route associated with an autonomous vehicle; determine an autonomous route risk value comprising an indication of an accident risk associated with traversal of the first travel route by a vehicle in an autonomous driving mode; determine a manual route risk value comprising an indication of an accident risk associated with traversal of the first travel route by a vehicle in a manual driving mode; responsive to determining, based on the autonomous route risk value and the manual route risk value, that the autonomous driving mode is associated with a lower risk of an accident, cause a driver of the autonomous vehicle to be notified that the autonomous driving mode is a safer mode for traversal of the first travel route; and responsive to determining, based on the autonomous route risk value and the manual route risk value, that the manual driving mode is associated with a lower risk of an accident, cause a driver of the autonomous vehicle to be notified that the manual driving mode is the safer mode for traversal of the first travel route. - View Dependent Claims (17, 18, 19, 20)
