Mode transition for an autonomous vehicle
First Claim
1. A method comprising:
- accessing, from a database, a confidence threshold for a geographic area, wherein the geographic area has at least one geographic characteristic;
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, wherein the confidence threshold corresponds to the at least one geographic characteristic;
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 when the comparison is within the confidence threshold for the geographic area based on the at least one geographic characteristic.

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.

13. An apparatus comprising:
-
at least one processor; and at least one memory including computer program code for one or more programs, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least perform; accessing a confidence threshold for at least one geographic area; calculating a vehicle confidence score based on sensor data; performing a comparison of the confidence threshold to the vehicle confidence score, wherein the confidence threshold corresponds to the at least one geographic area; and generating an autonomous driving command for a vehicle based on the comparison, wherein the autonomous driving command includes a transition to autonomous mode or a transition to manual mode when the comparison is within the confidence threshold for the at least one geographic area. - View Dependent Claims (14, 15, 16, 17, 18, 19)
