Abstract
Embodiments herein can determine an optimal route for an autonomous electric vehicle. The system may score viable routes between the start and end locations of a trip using a numeric or other scale that denotes how viable the route is for autonomy. The score is adjusted using a variety of factors where a learning process leverages both offline and online data. The scored routes are not based simply on the shortest distance between the start and end points but determine the best route based on the driving context for the vehicle and the user.

1-20. (canceled)
A vehicle, comprising:
- a first set of sensors to sense an environment surrounding the vehicle;
- a second set of sensors to sense an activity of an occupant in the vehicle;
- a third set of sensors to sense a state of the vehicle;
- a vehicle control system for autonomously controlling driving functions of the vehicle;
- a navigation system in communication with the first, second, and third sets of sensors and the vehicle control system, to provide a selected route to the vehicle control system for autonomously controlling the vehicle along the selected route;
- and
- a processor in communication with the first, second, and third sets of sensors, the navigation system, and the vehicle control system, the processor:
- receiving static route characteristics that are not anticipated to change for each of the two or more routes;
- receiving dynamic route characteristics that change for each of the two or more routes;
- selecting a level of autonomy, from among a plurality of levels of autonomy, based on the sensed activity of the occupant;
- selecting, based on the static route characteristics, the dynamic route characteristics, and occupant route preferences for each of the two or more routes, a route of the two or more routes that best fits the selected level of autonomy, the sensed environment surrounding the vehicle, and the sensed state of the vehicle;
- and
- providing the selected route to the navigation system.
A method, comprising:
- receiving, for each of two or more routes between a common start point and a common end point, static route characteristics that are not anticipated to change for each of the two or more routes;
- receiving dynamic route characteristics that change for each of the two or more routes;
- receiving sensor data about a sensed environment surrounding the vehicle, a sensed activity of the occupant of the vehicle, and a sensed state of the vehicle;
- selecting a level of autonomy, from among a plurality of levels of autonomy, based on the sensed activity of the occupant;
- selecting based on the static route characteristics, the dynamic route characteristics, and occupant route preferences for each of the two or more routes, a route of the two or more routes that best fits the selected level of autonomy, the sensed environment, and the sensed state of the vehicle;
- and
- providing route directions for the selected route to a vehicle control system for controlling the vehicle along the selected route.
A non-transitory information storage media having stored thereon one or more instructions, that when executed by one or more processors, cause a vehicle to perform a method, the method, comprising:
- receiving, for each of two or more routes between a common start point and a common end point, static route characteristics that are not anticipated to change for each of the two or more routes;
- receiving dynamic route characteristics that change for each of the two or more routes;
- receiving sensor data about a sensed environment surrounding the vehicle, a sensed activity of the occupant of the vehicle, and a sensed state of the vehicle;
- selecting a level of autonomy, from among a plurality of levels of autonomy, based on the sensed activity of the occupant;
- selecting, based on the static route characteristics and the dynamic route characteristics for each of the two or more routes, a route of the two or more routes that best fits the selected level of autonomy, the sensed environment, and the sensed state of the vehicle;
- and
- providing route directions for the selected route to a vehicle control system for controlling the vehicle along the selected route.
