Abstract

A system for autonomous driving comparison and evaluation comprises an input interface and a processor. The input interface is configured to receive trip information generated during a driver controlled trip and receive information from an autonomous driving system related to actions that the autonomous driving system would have taken had it been in control during the trip. The processor is configured to compare a trip factor of the driver controlled trip with a simulated trip factor that would have occurred had the autonomous driving system been in control.

Claims

1. A system for autonomous driving comparison and evaluation, comprising:

an input interface configured to;

receive trip information generated during a driver controlled trip;

receive driver assistance systems information from a driver assistance system relating to actions that the driver assistance system would have taken had it been in control during the driver controlled trip; and

a processor configured to;

determine simulated trip information using the driver assistance system information;

determine an actual trip factor based at least in part on the trip information;

determine a simulated trip factor based at least in part on the simulated trip information; and

determine a trip score based at least in part on the actual trip factor and the simulated trip factor.

2. The system of claim 1, wherein the processor is further configured to determine a driver score based at least in part on the trip score.

3. The system of claim 2, wherein the driver score is based at least in part on an old driver score.

4. The system of claim 1, wherein the trip factor comprises a travel time.

5. The system of claim 1, wherein the trip factor comprises a fuel consumption.

6. The system of claim 1, wherein the trip factor comprises a trip safety.

7. The system of claim 1, wherein the processor is further configured to detect a deviation between the driver controlled trip and the trip that would have occurred had the autonomous driving system been in control.

8. The system of claim 1, further comprising an output interface configured to provide a driver score.

9. The system as in claim 1, wherein determining a simulated trip information comprises determining a trip start location and a trip stop location.

10. The system as in claim 1, wherein determining a simulated trip information comprises determining whether the simulator follows a same route as an actual route.

11. The system as in claim 10, wherein determining a simulated trip information comprises in the event that the simulator follows the same route as the actual route, set simulation route to the actual route.

12. The system as in claim 10, wherein determining a simulated trip information comprises in the event that the simulator does not follow the same route as the actual route, set simulation route to the calculated route.

13. The system as in claim 12, wherein it is determined whether there are any anomalous events on the actual route.

14. The system as in claim 13, wherein in the event that there is/are anomalous event(s) on the actual route, indicating that there is/are anomalous event(s) to the simulator.

15. The system as in claim 13, wherein in the event that there are not any anomalous events on the actual route, determining simulated trip information for simulation route.

16. The system as in claim 1, wherein the driver assistance systems information comprises sensor information that is processed using a simulated driver assistance system.

17. The system as in claim 1, wherein the driver assistance systems information comprises installed driver assistance system information that is processed using a simulated driver assistance system.
