Abstract

This disclosure relates to a system and method for determining vehicle operator preparedness for vehicles that support both autonomous operation and manual operation. The system includes sensors configured to generate output signals conveying information related to vehicles and their operation. During autonomous vehicle operation, the system gauges the level of responsiveness of an individual vehicle operator through challenges and corresponding responses. Based on the level of responsiveness, a preparedness metric is determined for each vehicle operator individually.

First claim

What is claimed is:

1. A system configured to determine vehicle operator preparedness for vehicle operators of vehicles, wherein the vehicles support both an autonomous operation mode and a manual operation mode, the system configured to couple with a vehicle, wherein the vehicle operators include a vehicle operator for the vehicle, wherein the vehicle is operated autonomously, wherein continued autonomous operation of the vehicle requires the vehicle operator to exhibit a preparedness to assume control of the vehicle, the system comprising:
one or more processors configured to:
during the autonomous operation mode of the vehicle, effectuate presentation of one or more challenges to the vehicle operator to gauge a level of responsiveness of the vehicle operator, wherein the one or more challenges are presented to the vehicle operator at particular moments in time, and wherein determination of the particular moments in time is based at least in part on the preparedness exhibited by the vehicle operator;

detect one or more responses by the vehicle operator to the one or more challenges;
determine whether the one or more responses reflect an insufficient level of preparedness by the vehicle operator to assume control of the vehicle in the manual operation mode; and
responsive to the determination that the one or more responses reflect the insufficient level of preparedness by the vehicle operator to assume control of the vehicle in the manual operation mode, prompt the vehicle to modify vehicle operation of the vehicle.

2. The system of claim 1 , wherein the one or more processors are further configured to:
determine a preparedness metric value that reflects preparedness of the vehicle operator to assume control of the vehicle, wherein determination of the preparedness metric value is based on the one or more responses; and
perform a comparison of the preparedness metric value with a preparedness threshold level,
wherein the determination that the one or more responses reflect the insufficient level of preparedness by the vehicle operator to assume control of the vehicle is based on the comparison.

3. The system of claim 1 , wherein the determination of the particular moments in time is such that a frequency of presenting the one or more challenges is increased.

4. The system of claim 1 , wherein the determination of the particular moments in time is further based at least in part on one or more current weather parameters.

5. The system of claim 1 , wherein the determination of the particular moments in time is further based at least in part on one or more current traffic parameters.

6. The system of claim 1 , wherein the determination of the particular moments in time is further based at least in part on one or more current traffic parameters.

7. The system of claim 1 , wherein the determination of the particular moments in time is further based at least in part on a current location of the vehicle.

8. The system of claim 1 , wherein modification of the vehicle operation as prompted includes at least one of: (i) reducing speed of the vehicle, and (ii) a change in operation mode of the vehicle.

9. The system of claim 2 , wherein the one or more processors are further configured to:
measure an elapsed time between a presentation of an individual challenge and a detection of an individual response to the individual challenge; and
wherein the determination of the preparedness metric value is based on the elapsed time.

10. A method to determine vehicle operator preparedness for vehicle operators of vehicles, wherein the vehicles support both an autonomous operation mode and a manual operation mode, wherein the vehicles include a vehicle, wherein the vehicle operators include a vehicle operator for the vehicle, wherein the vehicle is operated autonomously, wherein continued autonomous operation of the vehicle requires the vehicle operator to exhibit a preparedness to assume control of the vehicle, the method comprising:
determining particular moments in time to present one or more challenges to the vehicle operator, wherein determination of the particular moments in time is based at least in part on the preparedness exhibited by the vehicle operator;
during the autonomous operation mode of the vehicle, effectuating presentation of the one or more challenges to the vehicle operator to gauge a level of responsiveness of the vehicle operator;
detecting one or more responses by the vehicle operator to the one or more challenges;
determining whether the one or more responses reflect an insufficient level of preparedness by the vehicle operator to assume control of the vehicle in the manual operation mode; and
responsive to determining that the one or more responses reflect the insufficient level of preparedness by the vehicle operator to assume control of the vehicle in the manual operation mode, prompting the vehicle to modify vehicle operation of the vehicle.

11. The method of claim 10 , further comprising:
determining a preparedness metric value that reflects preparedness of the vehicle operator to assume control of the vehicle, wherein determination of the preparedness metric value is based on the one or more responses; and
performing a comparison of the preparedness metric value with a preparedness threshold level;
wherein determining the one or more responses reflect the insufficient level of preparedness by the vehicle operator to assume control of the vehicle is based on the comparison.

12. The method of claim 10 , wherein the determination of the particular moments in time is such that a frequency of presenting the one or more challenges is increased.

13. The method of claim 10 , wherein the determination of the particular moments in time is further based at least in part on one or more current weather parameters.

14. The method of claim 10 , wherein the determination of the particular moments in time is further based at least in part on one or more current traffic parameters.

15. The method of claim 10 , wherein the determination of the particular moments in time is further based at least in part on one or more current traffic parameters.

16. The method of claim 10 , wherein the determination of the particular moments in time is further based at least in part on a current location of the vehicle.

17. The method of claim 11 , wherein modification of the vehicle operation as prompted includes at least one of: (i) reducing speed of the vehicle, and (ii) a change in operation mode of the vehicle.

18. The method of claim 11 , further comprising:
measuring an elapsed time between a presentation of an individual challenge and a detection of an individual response to the individual challenge; and
wherein the determination of the preparedness metric value is further based on the elapsed time.
