Abstract
A method for evaluating safety performance of an autonomous vehicle including comparing first sensor data characterizing a driver-operation of a vehicle to a first threshold to obtain a first driving quality value, comparing second sensor data characterizing an autonomous-vehicle-operation to a second threshold to obtain a second driving quality value, and determining, based at least in part on a comparing of the first and second driving quality values to each other, a safety performance of the autonomous-operated vehicle relative to the driver-operated vehicle, and a corresponding system.
Claims18
A method for evaluating safety performance of an autonomous vehicle, the method comprising:
- creating, by at least one processor, at least one arbitrary operational design domain based on at least one condition that is external to a driver-operated vehicle;
- controlling, by the at least one processor, an autonomous-operated vehicle to perform a first maneuver by an autonomous-vehicle-operation within the at least one operational design domain;
- controlling, by the at least one processor, at least one first sensor to sense first sensor data characterizing the autonomous-vehicle-operation while the autonomous-operated vehicle is being controlled to perform the autonomous-vehicle-operation within the at least one operational design domain;
- determining, bye the at least one processor, an autonomous-operated vehicle performance within the at least one operational design domain by comparing the first sensor data, obtained by the at least one first sensor sensing the first sensor data, to a first threshold to obtain a first driving quality value;
- determining, by the at least one processor, a driver-operated vehicle performance within the at least one operational design domain by comparing second sensor data characterizing a driver-operation of the driver-operated vehicle to perform a second maneuver within the at least one operational design domain to a second threshold to obtain a second driving quality value, wherein the second sensor data is obtained by at least one second sensor;
- performing a comparison, by the at least one processor, of the driver-operated vehicle performance to the autonomous-operated vehicle performance within the at least one operational design domain based on a similarity of at least one of environmental, a time of day, and road conditions when the first maneuver and the second maneuver were performed, wherein the at least one processor is configured to perform the comparison even when the first maneuver and the second maneuver are different;
- and
- determining, by the at least one processor, based at least in part on the comparison of the driver-operated vehicle performance to the autonomous-operated vehicle performance within the at least one operational design domain, a safety performance of the autonomous-operated vehicle relative to the driver-operated vehicle.
