Abstract
A scenario aware perception system (10) suitable for use on an automated vehicle includes a traffic-scenario detector (14), an object-detection device (24), and a controller (32). The traffic-scenario detector (14) is used to detect a present-scenario (16) experienced by a host-vehicle (12). The object-detection device (24) is used to detect an object (26) proximate to the host-vehicle (12). The controller (32) is in communication with the traffic-scenario detector (14) and the object-detection device (24). The controller (32) configured to determine a preferred-algorithm (36) used to identify the object (26). The preferred-algorithm (36) is determined based on the present-scenario (16).
Claims15
A method for controlling an autonomous vehicle, comprising:
- determining a present traffic scenario of a plurality of possible traffic scenarios of the autonomous vehicle, wherein each possible traffic scenario characterizes a configuration of a roadway;
- selecting a respective object identification algorithm associated with the present traffic scenario, wherein the selected object identification algorithm identifies target objects that move in an expected direction of travel on the roadway characterized by the present traffic scenario;
- and
- identifying one or more target objects proximate to the autonomous vehicle using the selected object identification algorithm, comprising identifying motion of the one or more target objects in accordance with the expected direction of travel of the target objects characterized by the present traffic scenario.
An autonomous vehicle comprising:
- a traffic scenario detector configured to determine a present traffic scenario of a plurality of possible traffic scenarios of the autonomous vehicle, wherein each possible traffic scenario characterizes a configuration of a roadway;
- a controller configured to select a respective object identification algorithm associated with the present traffic scenario, wherein the selected object identification algorithm identifies target objects that move in an expected direction of travel on the roadway characterized by the present traffic scenario;
- and
- an object detection device configured to identify one or more target objects proximate to the autonomous vehicle using the selected object identification algorithm and to identify motion of the one or more target objects in accordance with the expected direction of travel of the target objects characterized by the present traffic scenario.
One or more non-transitory computer storage media storing instructions that are operable, when executed by one or more computers, to cause the one or more computers to perform operations comprising:
- determining a present traffic scenario of a plurality of possible traffic scenarios of an autonomous vehicle, wherein each possible traffic scenario characterizes a configuration of a roadway;
- selecting a respective object identification algorithm associated with the present traffic scenario, wherein the selected object identification algorithm identifies target objects that move in an expected direction of travel on the roadway characterized by the present traffic scenario;
- and
- identifying one or more target objects proximate to the autonomous vehicle using the selected object identification algorithm, comprising identifying motion of the one or more target objects in accordance with the expected direction of travel of the target objects characterized by the present traffic scenario.
