Mode Transition for an Autonomous Vehicle
First Claim
1. A method comprising:
- accessing, from a database, a confidence threshold for a geographic area;
calculating, using a processor, a vehicle confidence level based on at least one confidence factor;
performing a comparison of the confidence threshold to the vehicle confidence level;
generating a driving mode command for a vehicle based on the comparison; and
transitioning, automatically using the processor, the vehicle to or from an autonomous driving mode based on the vehicle mode command.

Abstract
An autonomous vehicle may be operable in an autonomous mode and a manual mode. A confidence threshold is accessed from a database. The confidence threshold may be associated with a particular geographic area containing the autonomous vehicle. The confidence threshold may be constant for the geographic area accessible by the autonomous vehicle. A computing device calculates a vehicle confidence level based on at least one confidence factor and compares the confidence threshold to the vehicle confidence level. The computing device generates a driving mode command for a vehicle based on the comparison. In one example, the driving mode command transitions the autonomous vehicle to the autonomous mode, if applicable, when the vehicle confidence score exceeds the confidence threshold. In one example, the driving mode command transitions the autonomous vehicle to the manual mode, if applicable, when the vehicle confidence score does not exceed the confidence threshold.
