Method and system for establishing whether a road section is suitable for autonomous vehicle driving
First Claim
1. A method performed by a suitability determining system for establishing whether a road section is suitable for at least semi-autonomous vehicle driving, the suitability determining system being associated with a system supporting communication with one or more vehicles, the method comprising:
- identifying a specific road section comprising at least one lane and delimited by at least one lateral road boundary;
deriving from at least a first estimate providing vehicle a respective utilization direction estimate along with a corresponding respective detection confidence value for each of respective lanes detected by the at least first estimate providing vehicle along at least a portion of the specific road section, the respective utilization direction estimate being based on detected driving trajectories detected by the at least first estimate providing vehicle of one or more surrounding vehicles along one or more of the respective detected lanes;
determining a respective summarized direction utilization estimate along with a corresponding respective summarized confidence value for each of the respective detected lanes; and
determining an autonomous driving suitability indication applicable for the specific road section, the autonomous driving suitability indication indicating that the specific road section is suitable for at least semi-autonomous driving provided that;
all of the determined summarized direction utilization estimates indicate equally directed utilization, andall of the determined summarized confidence values are above respective confidence thresholds.

Abstract
A suitability determining system for establishing whether a road section is suitable for at least semi-autonomous vehicle driving is described. The system identifies a road section including at least one lane and delimited by at least one lateral road boundary, and derives from at least a first estimate providing vehicle a respective utilization direction estimate along with a corresponding respective detection confidence value for each of respective lanes detected by the estimate providing vehicle along the road section. The system determines a respective summarized direction utilization estimate along with a corresponding respective summarized confidence value for each respective detected lane, and determines an autonomous driving suitability indication applicable for the road section, which indicates the road section is suitable for at least semi-autonomous driving provided all determined summarized direction utilization estimates indicate equally directed utilization and all determined summarized confidence values exceed respective confidence thresholds.
