Abstract

A system for automated operation of a host-vehicle includes a sensor and a controller. The sensor is configured to detect an other-vehicle proximate to a host-vehicle. The controller is in communication with the sensor. The controller is configured to determine a behavior-classification of the other-vehicle based on lane-keeping-behavior of the other-vehicle relative to a roadway traveled by the other-vehicle, and select a travel-path for the host-vehicle based on the behavior-classification. In one embodiment, the behavior-classification of the other-vehicle is based on a position-variation-value indicative of how much an actual-lane-position of the other-vehicle varies from a center-lane-position of the roadway. In yet another embodiment, the behavior-classification of the other-vehicle is based on a vector-difference-value indicative of how much a vehicle-vector of the other-vehicle differs from a lane-vector of the roadway.

First claim

We claim:

1 . A system for automated operation of a host-vehicle, said system comprising:
a sensor configured to detect an other-vehicle proximate to a host-vehicle; a controller in communication with the sensor, said controller configured to determine a behavior-classification of the other-vehicle based on lane-keeping-behavior of the other-vehicle relative to a roadway traveled by the other-vehicle, and select a travel-path for the host-vehicle based on the behavior-classification.

2 . The system in accordance with claim 1 , wherein
the behavior-classification of the other-vehicle is based on a position-variation-value indicative of how much an actual-lane-position of the other-vehicle varies from a center-lane-position of the roadway.

3 . The system in accordance with claim 2 , wherein
the behavior-classification of the other-vehicle is classified as predictable when the position-variation-value is less than a variation-threshold, and the travel-path includes passing the other-vehicle while the behavior-classification is predictable.

4 . The system in accordance with claim 2 , wherein
the behavior-classification of the other-vehicle is classified as erratic when the position-variation-value is not less than a variation-threshold, and the travel-path includes not passing the other-vehicle while the behavior-classification is erratic.

5 . The system in accordance with claim 1 , wherein
the behavior-classification of the other-vehicle is based on a vector-difference-value indicative of how much a vehicle-vector of the other-vehicle differs from a lane-vector of the roadway.

6 . The system in accordance with claim 1 , wherein
the behavior-classification of the other-vehicle is classified as out-of-control when the vector-difference-value violates a difference-threshold, and the travel-path includes changing lanes to avoid the other-vehicle while the behavior-classification is out-of-control.
