Abstract

Among other things, a determination is made that intervention in an operation of one or more autonomous driving capabilities of a vehicle is appropriate. Based on the determination, a person is enabled to provide information for an intervention. The intervention is caused in the operation of the one or more autonomous driving capabilities of the vehicle.

Claims

1. A method comprising:

causing a vehicle to drive in an autonomous mode on a road, the vehicle comprising one or more autonomous driving capabilities;

receiving an intervention regarding an operation of the one or more autonomous driving capabilities; and

analyzing the intervention and configuring, based on the intervention, one or more hardware components or one or more software processes of the vehicle.

2. The method of claim 1, in which an intervention comprises a current location of the vehicle.

3. The method of claim 2, in which analyzing the intervention comprises treating the current location in the intervention as prior knowledge and using an inference algorithm to update the current location.

4. The method of claim 1, in which an intervention comprises a goal location for the vehicle.

5. The method of claim 4, in which analyzing the intervention comprises treating the goal location in the intervention as prior knowledge and using an inference algorithm to update the goal location.

6. The method of claim 1, in which an intervention comprises a trajectory for the vehicle.

7. The method of claim 6, in which analyzing the intervention comprises treating the trajectory in the intervention as prior knowledge and using an inference algorithm to update the trajectory.

8. The method of claim 1, in which an intervention comprises one or more trajectory sampling points for the vehicle.

9. The method of claim 6, in which analyzing the intervention comprises treating the one or more trajectory sampling points as prior knowledge and using an inference algorithm to update the one or more trajectory sampling points.

10. The method of claim 6, in which analyzing the intervention comprises inferring a trajectory or a trajectory segment based on the one or more trajectory sampling points.

11. The method of claim 10, in which inferring a trajectory or a trajectory segment is based on one or more trajectory primitives.

12. The method of claim 10, in which inferring a trajectory or a trajectory segment comprises concatenating two shorter trajectory segments, the concatenating comprises smoothing the shorter trajectory segments and smoothing speed profiles across the shorter trajectory segments.

13. The method of claim 1, in which an intervention comprises specifying one or more un-traversable road segments.

14. The method of claim 1, in which an intervention comprises setting a speed profile.

15. The method of claim 14, in which analyzing the intervention comprises treating the speed profile as prior knowledge and using an inference algorithm to update the speed profile.

16. The method of claim 1, in which analyzing the intervention comprises inferring a speed profile by a learning algorithm.

17. The method of claim 1, in which analyzing the intervention comprises inferring a steering angle by a learning algorithm.

18. The method of claim 1, in which analyzing the intervention comprises enabling, editing or disabling a hardware component or a software process.

19. The method of claim 1, in which analyzing the intervention comprises enabling, editing or disabling a subcomponent of a hardware component or a processing step of a software process.

20. The method of claim 1, in which an intervention comprises overwriting a travel preference or a travel rule.

21. The method of claim 1, in which an intervention comprises editing data, the data comprising one or more of the following:

a map, sensor data in the vehicle or a related AV system, trajectory data in the vehicle or a related AV system, vision data in the vehicle or a related AV system, or any past data in the vehicle or a related AV system.
