Abstract

Aspects of the present disclosure relate generally to identifying and displaying traffic lanes that are available for autonomous driving. This information may be displayed to a driver of a vehicle having an autonomous driving mode, in order to inform the driver of where he or she can use the autonomous driving mode. In one example, the display may visually distinguishing between lanes that are available for auto-drive from those that are not. The display may also include an indicator of the position of a lane (autodrive or not) currently occupied by the vehicle. In addition, if that lane is an autodrive lane the display may include information indicating how much further the vehicle may continue in the autonomous driving mode in that particular lane. The display may also display information indicating the remaining autodrive distance in other lanes as well as the lane with the greatest remaining autodrive distance.

Claims

1. A computer-implemented method comprising:

accessing, by one or more processors of the computer, detailed map information identifying the locations of autodrive lanes, wherein each autodrive lane is a lane of a roadway pre-approved for an autonomous driving mode of the vehicle, the autonomous driving mode allowing a driver to relinquish control of the vehicle to a computer;

identifying, by the one or more processors, an autodrive lane based on at least the detailed map information and a route being followed by the vehicle;

generating, by the one or more processors, display information including lanes and identifying which of the lanes is the autodrive lane, the display information including a visual marker identifying a range of the lane for the autonomous driving mode; and

providing, by the one or more processors, the display information for display to the driver.

2. The method of claim 1, further comprising displaying the display information when the vehicle is not being operated in the autonomous driving mode.

3. The method of claim 1, wherein the visual marker includes an icon representative of a construction zone in order to identify that the range relates to the construction zone.

4. The method of claim 3, wherein the display information includes a visual arrangement where the icon is arranged below a representation of the lanes.

5. The method of claim 3, wherein the display information includes a visual arrangement where the icon is arranged below a representation of the autodrive lane and closer to the autodrive lane than any representation of another lane.

6. The method of claim 1, wherein the visual marker includes text identifying the range.

7. The method of claim 1, wherein the display information includes a visual arrangement where the visual marker is arranged below a representation of the lanes.

8. The method of claim 1, wherein the display information includes a first display color for the autodrive lane and a second display color for another lane, the first and second display color being different.

9. The method of claim 1, further comprising a second visual indicator representing a location of the vehicle within one of the lanes.

10. The method of claim 1, wherein the visual marker includes an icon representative of a turn required by route in order to identify that the range relates to the turn.

11. The method of claim 1, wherein the visual marker includes an icon representative of a traffic merge required by route in order to identify that the range relates to the traffic merge.

12. The method of claim 1, wherein the visual marker includes an icon representative of a reasoning for the range.

13. A system comprising at least one computer having one or more processors configured to:

access detailed map information identifying the locations of autodrive lanes, wherein each autodrive lane is a lane of a roadway pre-approved for an autonomous driving mode of the vehicle, the autonomous driving mode allowing a driver to relinquish control of the vehicle to a computer;

identify an autodrive lane based on at least the detailed map information and a route being followed by the vehicle;

generate display information including lanes and identifying which of the lanes is the autodrive lane, the display information including a visual marker identifying a range of the lane for the autonomous driving mode; and

provide the display information for display to the driver.

14. The system of claim 13, wherein the one or more processors are further configured to display the display information when the vehicle is not being operated in the autonomous driving mode.

15. The system of claim 13, wherein the visual marker includes an icon representative of a construction zone in order to identify that the range relates to the construction zone.

16. The system of claim 15, wherein the display information includes a visual arrangement where the icon is arranged below a representation of the lanes.

17. The system of claim 16, wherein the display information includes a visual arrangement where the icon is arranged below a representation of the autodrive lane and closer to the autodrive lane than any representation of another lane.

18. The system of claim 13, wherein the display information includes a visual arrangement where the visual marker is arranged below a representation of the lanes.

19. The system of claim 13, wherein the visual marker includes an icon representative of a turn required by route in order to identify that the range relates to the turn.

20. The system of claim 13, wherein the visual marker includes an icon representative of a traffic merge required by route in order to identify that the range relates to the traffic merge.
