Abstract

An autonomous vehicle which includes multiple independent control systems that provide redundancy as to specific and critical safety situations which may be encountered when the autonomous vehicle is in operation.

First claim

What is claimed is:

1. An autonomous vehicle control system for controlling an autonomous vehicle, the autonomous vehicle control system comprising:
one or more processors; and
one or more tangible, non-transitory, computer readable media storing instructions that are executable by the one or more processors to cause the autonomous vehicle control system to perform operations, the operations comprising:
receiving, from one or more first sensors, a first sensor input descriptive of an environment of the autonomous vehicle;
determining, using a first control subsystem and based at least in part on the first sensor input, a first determined state of the environment, the first determined state associated with a confidence score;
receiving, from one or more second sensors, a second sensor input descriptive of the environment;
determining, using a second control subsystem and based at least in part on the second sensor input, a second determined state of the environment; and
determining, based at least in part on the confidence score, to implement a vehicle response output of the second control subsystem, the vehicle response output based at least in part on the second determined state of the environment.

2. The autonomous vehicle control system of claim 1 , wherein the vehicle response output of the second control subsystem is implemented in lieu of a vehicle response output of the first control subsystem.

3. The autonomous vehicle control system of claim 1 , wherein the operations comprise:
determining that the confidence score satisfies a threshold; and
determining to use the vehicle response output of the second control subsystem based on the confidence score satisfying the threshold.

4. The autonomous vehicle control system of claim 1 , wherein the one or more first sensors comprise camera sensors and the one or more second sensors comprise Lidar sensors.

5. The autonomous vehicle control system of claim 1 , wherein the one or more first sensors consist of one or more camera sensors and the one or more second sensors consist of one or more Lidar sensors.

6. The autonomous vehicle control system of claim 1 , wherein the operations comprise:
determining, based on at least one of the first sensor input or the second sensor input, a particular confidence indicator associated with the environment; and
determining, based at least in part on the particular confidence indicator, to implement the vehicle response output of the second control subsystem.

7. The autonomous vehicle control system of claim 6 , wherein the particular confidence indicator comprises an event associated with a level of confidence indicative of an ability of the second control subsystem to respond to the event.

8. One or more tangible, non-transitory, computer readable media storing instructions that are executable by one or more processors to cause an autonomous vehicle control system of an autonomous vehicle to perform operations, the operations comprising:
receiving, from one or more first sensors, a first sensor input descriptive of an environment of the autonomous vehicle;
determining, using a first control subsystem and based at least in part on the first sensor input, a first determined state of the environment, the first determined state associated with a confidence score;
receiving, from one or more second sensors, a second sensor input descriptive of the environment;
determining, using a second control subsystem and based at least in part on the second sensor input, a second determined state of the environment; and
determining, based at least in part on the confidence score, to implement a vehicle response output of the second control subsystem, the vehicle response output based at least in part on the second determined state of the environment.

9. The one or more tangible, non-transitory, computer readable media of claim 8 , wherein the vehicle response output of the second control subsystem is implemented in lieu of a vehicle response output of the first control subsystem.

10. The one or more tangible, non-transitory, computer readable media of claim 8 , wherein the operations comprise:
determining that the confidence score satisfies a threshold; and
determining to use the vehicle response output of the second control subsystem based on the confidence score satisfying the threshold.

11. The one or more tangible, non-transitory, computer readable media of claim 8 , wherein the one or more first sensors comprise camera sensors and the one or more second sensors comprise Lidar sensors.

12. The one or more tangible, non-transitory, computer readable media of claim 8 , wherein the one or more first sensors consist of one or more camera sensors and the one or more second sensors consist of one or more Lidar sensors.

13. The one or more tangible, non-transitory, computer readable media of claim 8 , wherein the operations comprise:
determining, based on at least one of the first sensor input or the second sensor input, a particular confidence indicator associated with the environment; and
determining, based at least in part on the particular confidence indicator, to implement the vehicle response output of the second control subsystem.

14. The one or more tangible, non-transitory, computer readable media of claim 13 , wherein the particular confidence indicator comprises an event associated with a lowered level of confidence.

15. One or more tangible, non-transitory, computer readable media storing instructions that are executable by one or more processors to cause an autonomous vehicle control system of an autonomous vehicle to perform operations, the operations comprising:
receiving, from one or more first sensors, a first sensor input descriptive of an environment of the autonomous vehicle;
determining, using a first control subsystem and based at least in part on the first sensor input, a first determined state of the environment, the first determined state associated with a confidence score;
receiving, from one or more second sensors, a second sensor input descriptive of the environment;
determining, using a second control subsystem and based at least in part on the second sensor input, a second determined state of the environment; and
determining, based at least in part on the confidence score, to implement a vehicle response output of the second control subsystem, the vehicle response output based at least in part on the second determined state of the environment.

16. The one or more tangible, non-transitory, computer readable media of claim 15 , wherein the vehicle response output of the second control subsystem is implemented in lieu of a vehicle response output of the first control subsystem.

17. The one or more tangible, non-transitory, computer readable media of claim 15 , wherein the operations comprise:
determining that the confidence score satisfies a threshold; and
determining to use the vehicle response output of the second control subsystem based on the confidence score satisfying the threshold.

18. The one or more tangible, non-transitory, computer readable media of claim 15 , wherein the one or more first sensors comprise camera sensors and the one or more second sensors comprise Lidar sensors.

19. The one or more tangible, non-transitory, computer readable media of claim 15 , wherein the one or more first sensors consist of one or more camera sensors and the one or more second sensors consist of one or more Lidar sensors.

20. The one or more tangible, non-transitory, computer readable media of c
