Abstract
An autonomous vehicle control system that determines, using a location device, an individual roadway segment on which a vehicle is located, accesses, using one or more processors, a confidence score associated with the individual roadway segment, outputs one or more vehicle control signals from an automated drive controller communicatively coupled to the vehicle, which are based on one or more vehicle control settings of an individual autonomous operation profile associated with the confidence score, and operates the vehicle based on the one or more vehicle control signals output by the automated drive controller.
Claims20
An autonomous vehicle control system comprising:
- one or more processors;
- a location device communicatively coupled to the one or more processors;
- one or more memory modules communicatively coupled to the one or more processors;
- a plurality of autonomous operation profiles stored in the one or more memory modules, wherein each of the plurality of autonomous operation profiles comprise one or more vehicle control settings for an automated drive controller communicatively coupled to a vehicle;
- a plurality of confidence scores stored in the one or more memory modules, wherein:
- the plurality of confidence scores are associated with the plurality of roadway segments such that the autonomous vehicle control system comprises a confidence score for each individual roadway segment of the plurality of roadway segments;
- and
- each confidence score is associated with an individual autonomous operation profile of the plurality of autonomous operation profiles;
- and
- machine readable instructions stored in the one or more memory modules that cause the autonomous vehicle control system to perform at least the following when executed by the one or more processors:
- determine, using the location device, an individual roadway segment on which the vehicle is located;
- access, using the one or more processors, a confidence score associated with the individual roadway segment;
- output one or more vehicle control signals from the automated drive controller, wherein the one or more vehicle control signals are based on one or more vehicle control settings of an individual autonomous operation profile associated with the confidence score;
- and
- operate the vehicle based on the one or more vehicle control signals output by the automated drive controller.

A method of operating a vehicle, the method comprising:
- determining, using a location device communicatively coupled to one or more processors, an individual roadway segment on which the vehicle is located;
- accessing, using the one or more processors, a confidence score associated with the individual roadway segment, wherein the confidence score is stored in one or more memory modules communicatively coupled to the one or more processors;
- outputting one or more vehicle control signals from an automated drive controller communicatively coupled to the vehicle, wherein the one or more vehicle control signals are based on one or more vehicle control settings of an individual autonomous operation profile associated with the confidence score;
- and
- operating the vehicle based on the one or more vehicle control signals output by the automated drive controller.
2 more elements
A method of operating a vehicle, the method comprising:
- monitoring, using one or more observation sensors communicatively coupled to one or more processors and one or more memory modules, a vehicle operating environment of a vehicle as the vehicle travels along a first roadway segment located in the vehicle operating environment;
- outputting a sensor signal comprising roadway information regarding the vehicle operating environment from the one or more observation sensors, such that the roadway information is received by the one or more memory modules;
- storing the roadway information in the one or more memory modules, wherein the one or more memory modules also store:
- a plurality of autonomous operation profiles, each comprising one or more vehicle control settings for an automated drive controller communicatively coupled to the vehicle;
- and
- a plurality of confidence scores associated with a plurality of roadway segments, wherein:
- an individual confidence score is associated with each individual roadway segment of the plurality of roadway segments such that a first confidence score is associated with the first roadway segment;
- and
- each confidence score is associated with an individual autonomous operation profile of the plurality of autonomous operation profiles;
- and
- increasing the first confidence score based on the roadway information regarding the vehicle operating environment of the first roadway segment such that the first confidence score comprises a first updated confidence score.
