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.

The method according to claim 1 wherein obtaining turning cues includes determining that a programmed route in a navigation system indicates a turn, and wherein determining the confidence level that the host vehicle intends to make a turn includes increasing the confidence level if a programmed turn is in the navigation system. 8. The method according to claim 1 wherein obtaining turning cues includes determining that a distance to a remote vehicle ahead of the host vehicle is increasing, and wherein 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. 9. The method according to claim 1 wherein obtaining turning cues includes determining that the driver of the host vehicles attention is turned to the left or right, and wherein determining the confidence level that the host vehicle intends to make a turn includes increasing the confidence level if the vehicle driver attention is to the left or right. 10. The method according to claim 1 wherein determining the confidence level that the host vehicle intends to make a turn includes adapting the determination of the confidence level based on a driver's previous behavior. 11. The method according to claim 1 wherein obtaining a plurality of turning cues includes obtaining information and data from one or more of vehicle speed, vehicle velocity, vehicle position, a map database, long range sensors on the vehicle, short range sensors on the vehicle, cameras on the vehicle, lidar sensors on the vehicle, V2X communications, host vehicle path history, internet communications and satellite communications. 12. The method according to claim 1 wherein weighting the cues includes adjusting the weighting by one or more of duration of a traffic signal, driver's previous behavior, whether the host vehicle is near the intersection, distance from the intersection and type of intersection. 13. The method according to claim 1 further comprising determining whether the driver of the host vehicle intends to yield to oncoming traffic or cut-across in front of oncoming traffic when making a left turn. 14. The method according to claim 13 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 the on-coming 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. 15. The method according to claim 14 wherein determining whether the driver intends to cut-across in front of on-coming traffic includes determining that the host vehicle intends to cut-across in front of the on-coming traffic from a starting small velocity if the host vehicle velocity is less than a second predetermined velocity that is less than the first predetermined velocity, the road wheel angle of the host vehicle is greater than a second predetermined road wheel angle that is less than the first predetermined road wheel angle, and an acceleration of the host vehicle is greater than a predetermined acceleration. 16. The method according to claim 15 wherein determining whether the driver intends to cut-across in front of on-coming traffic includes determining that the driver of the host vehicle intends to cut-across in front of on-coming traffic from a high velocity if the road wheel angle of the host vehicle is greater than a third predetermined road wheel angle that is less than the second predetermined road wheel angle, a projected host vehicle speed is greater than a third predetermined velocity that is greater than the second predetermined velocity and the host vehicle is decelerating less than a predetermined deceleration. 17. 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, said plurality of turning cues including whether the host vehicle is in a left or right turn only travel lane, whether the host vehicle has recently turned into a left lane or a right lane, whether the host vehicle has recently moved into a high traffic volume lane, whether the host vehicle has made previous frequent left or right turns at a particular location, whether a driver has turned on a left or right turn signal, whether a distance to remote vehicle ahead of the host vehicle is increasing, and whether the attention of the driver of the host vehicle is turned to the left, oncoming traffic or the right; and determining a confidence level that the host vehicle will make a left or right turn based on an assessment of one or more of the turning cues. 18.
