WIDTH CALIBRATION OF LANE DEPARTURE WARNING SYSTEM
First Claim
1. A method for providing lane departure warning functionality for a vehicle, the method comprising:
- determining that a vehicle equipped with a lane departure warning system has a trailer attached thereto;
acquiring at least one of trailer width information and extended width side view mirror width information after determining that the vehicle has the trailer attached thereto; and
calibrating the lane departure warning system using at least one of said trailer width information and said extended width side view mirror width information in response to receiving at least one of said trailer width information and said extended width side view mirror width information such that the lane departure warning systems determines instances of unintended lane departure as a function of at least one of a width defined by the trailer and a width defined an extended width side view mirror attached to the vehicle.

Abstract
A lane departure warning system has a trailer detector for detecting that a trailer is attached to a vehicle, a lane boundary detector for detecting a position of a lane boundary on a roadway over which the vehicle is travelling, and an information processor including a calibrator for generating calibration parameters used in determining an unintended lane departure event with respect to the lane boundary. The information processor initiates a process for allowing a vehicle operator to provide trailer width information when the trailer detector indicates that the vehicle has the trailer attached thereto. The trailer width information is used by the information processor for generating the calibration parameters as a function of a width of the trailer.

13. A lane departure warning system, comprising:
-
a trailer detector for detecting that a trailer is attached to a vehicle; a lane boundary detector for detecting a position of a lane boundary on a roadway over which the vehicle is traveling; and an information processor including a calibrator for generating calibration parameters used in determining an unintended lane departure event with respect to the lane boundary, wherein the information processor initiates a process for allowing a vehicle operator to provide trailer width information when the trailer detector indicates that the vehicle has the trailer attached thereto and wherein the trailer width information is used by the information processor for generating said calibration parameters as a function of a width of the trailer. - View Dependent Claims (14, 15, 16, 17, 18)

19. A non-transitory processor-readable medium having tangibly embodied thereon and accessible therefrom a set of instructions interpretable by at least one data processing device, said set of instructions configured for causing said at least one data processing device to carry out operations for:
-
determining that a vehicle equipped with a lane departure warning system has a trailer attached thereto; acquiring trailer width information after determining that the vehicle has the trailer attached thereto; and calibrating the lane departure warning system using said trailer width information in response to receiving said trailer width information such that the lane departure warning systems determines instances of unintended lane departure as a function of a width of the trailer as opposed to the width of the vehicle. - View Dependent Claims (20, 21, 22, 23)
