Determining driver intention at traffic intersections for automotive crash avoidance
First Claim

1. A method for determining whether a driver of a host vehicle intends to make a turn, said method comprising:
- obtaining, by a processor, a plurality of turning cues that identify external parameters around the host vehicle and/or define operating conditions of the host vehicle, wherein obtaining turning cues includes determining that a distance to a remote vehicle ahead of the host vehicle is increasing;
determining, by the processor, a confidence level that the host vehicle intends to make a left or right turn based on the turning cues where determining the confidence level includes weighting each of the cues based on current driving operating conditions and determining the confidence level that the host vehicle intends to make a turn includes increasing the confidence level of a left or right turn if the distance is increasing;
comparing, by the processor, the confidence level to a threshold; and
providing a warning, via a warning device, to a vehicle and/or performing a vehicle control action, via a controller, on the vehicle in response to the confidence level exceeding the threshold.

Abstract
A system and method for determining whether a driver of a host vehicle intends to make a left or right turn with a certain level of confidence. The method obtains a plurality of turning cues that identify external parameters around the host vehicle and/or define operating conditions of the host vehicle, and determines a confidence level that the host vehicle will make a left or right turn based on the turning cues, where determining the confidence level includes weighting each of the cues based on current vehicle operating conditions.

16. A method for determining whether a driver of a host vehicle intends to make a turn, said method comprising:
-
obtaining a plurality of turning cues that identify external parameters around the host vehicle and/or define operation of the host vehicle; and determining a confidence level that the host vehicle intends to make a left or right turn based on the turning cues, wherein determining the confidence level includes determining whether the driver of the host vehicle intends to yield to on-coming traffic or cut-across in front of on-coming traffic when making a left turn, wherein determining whether the driver intends to cut-across in front of on-coming traffic includes determining whether the host vehicle intends to cut-across from a stationary or creep condition if the host vehicle velocity is less than a first predetermined velocity, a road wheel angle of the host vehicle is greater than a first predetermined road wheel angle, and a vehicle brake pedal is not pressed; comparing, by the processor, the confidence level to a threshold; and providing a warning, via a warning device, to a vehicle and/or performing a vehicle control action, via a controller, on the vehicle in response to the confidence level exceeding the threshold. - View Dependent Claims (17, 18)
