METHODS OF IMPROVING PERFORMANCE OF AUTOMOTIVE INTERSECTION TURN ASSIST FEATURES
First Claim
1. A method for collision threat assessment on a host vehicle traveling on a roadway, said method comprising:
- determining if the host vehicle is likely to turn at or near an intersection with a predetermined level of confidence;
obtaining velocity and position data of the host vehicle using sensors onboard the host vehicle;
obtaining velocity and position data of one or more remote vehicles or other objects at or near the intersection;
determining, using a processor in a controller, a predicted path of the host vehicle based on the velocity and position data, along with yaw rate or road wheel angle of the host vehicle;
determining, using the processor, a predicted path of one or more of the remote vehicles based on the velocity and position data;
issuing a warning to a driver of the host vehicle, by the controller, if the host vehicle and one of the remote vehicles may collide based on the predicted paths; and
providing, using the processor, additional collision analysis to reduce false positive warnings and false negative warnings for specialized host vehicle circumstances.

Abstract
A system and method for warning a vehicle driver of a potential collision when turning left or right at or near an intersection, where the system and method provide additional analysis to limit false positive and false negative warnings based on specialized circumstances. The method includes determining if the host vehicle is likely to turn at or near the intersection, and obtaining speed, velocity and position data of the host vehicle and any relevant remote vehicles. The method determines a predicted path of the host vehicle and the remote vehicles based on the speed, velocity and position data, and issues a warning to a driver of the host vehicle if the host vehicle and one of the remote vehicles may collide based on the predicted paths. If the host vehicle is in a specialized circumstance, the method provides additional collision analysis to reduce false positive warnings and/or false negative warnings.

13. A method for determining whether a host vehicle traveling on a roadway is turning at an intersection or driveway or making a lane change, said method comprising:
-
obtaining velocity and position data of the host vehicle using sensors onboard the host vehicle; determining, using a processor in a controller, a predicted path of the host vehicle based on the velocity and position data, along with yaw rate or road wheel angle of the host vehicle; and determining, using the processor, whether the host vehicle is turning at the intersection or driveway or making a lane change based on the data and the predicted path. - View Dependent Claims (14, 15, 16, 18)
