Modifying vehicle behavior based on confidence in lane estimation
First Claim
Patent Images
1. A method, comprising:
- receiving, by a computing device, map information indicative of lane boundaries on a road on which a vehicle is travelling;
determining, by the computing device, that the map information indicative of the lane boundaries on the road is unreliable;
in response to determining that the map information is unreliable, receiving additional lane information from at least one on-board sensor coupled to the vehicle;
estimating, by the computing device, the lane boundaries based on the additional lane information;
determining a level of confidence for the estimated lane boundaries based on the additional lane information; and
determining, by the computing device, a path for the vehicle based on the level of confidence and the estimated lane boundaries.

Abstract
Methods and systems for modifying vehicle behavior based on confidence in lane estimation are described. In an example, a computing device may be configured to receive lane information relating to locations of lane boundaries and may be configured to estimate a lane boundary on a road on which the vehicle is traveling, based on the lane information. The computing device also may be configured to determine a level of confidence for the estimated lane boundary, modify a driving behavior for the vehicle based on the level of confidence, and also may be configured to control the vehicle based on the modified driving behavior.

8. A system, comprising:
-
at least one sensor coupled to a vehicle; at least one processor in communication with the at least one sensor; and data storage comprising instructions that, when executed by the at least one processor, cause the system to perform functions comprising; receiving map information indicative of lane boundaries on a road on which the vehicle is travelling; determining that the map information indicative of the lane boundaries on the road is unreliable; in response to determining that the map information is unreliable, receiving additional lane information from the at least one sensor; estimating the lane boundaries based on the additional lane information; determining a level of confidence for the estimated lane boundaries based on the additional lane information; and determining a path for the vehicle based on the level of confidence and the estimated lane boundaries. - View Dependent Claims (9, 10, 11, 12, 13, 14)
