Vehicle lane departure warning system having trailer mode and method
First Claim
1. A vehicle lane departure warning system having a trailer mode, said system comprising:
- an imager capturing images of a roadway proximate to a vehicle;
an input receiving a towing signal indicative of whether the vehicle is towing a trailer;
a processor processing the captured images and determining whether the vehicle or trailer is expected to be departing from a lane on the roadway based on the captured images and a threshold width value, wherein the processor further selects the threshold width value based on the input towing signal such that an enhanced threshold width value is employed when the vehicle is towing a trailer; and
an output for outputting a lane departure warning signal based on the processed images and selected threshold width value.

Abstract
A vehicle lane departure warning system and method are provided having a trailer mode. The system includes an imager capturing images of a roadway forward of a vehicle and an input receiving a towing signal indicative of whether the vehicle is towing a trailer. The system also includes a processor for processing the captured images and determining whether the vehicle or trailer is expected to be departing from a lane on the roadway based on the captured images and a threshold width value. The processor selects the threshold width value based on the input towing signal such that an enhanced threshold width value is employed when the vehicle is towing a trailer. An output is provided for outputting a lane departure warning signal based on the processed images and selected threshold width value.

8. A method of detecting a vehicle departing from a lane on a roadway
with a trailer mode, said method comprising the steps of: -
capturing images of the roadway proximate to the vehicle with a camera; processing the captured images from the camera to determine whether the vehicle or trailer is expected to be departing from a lane on the roadway based on the captured images and a threshold width value; monitoring an input to detect a towing signal indicative of whether the vehicle is towing a trailer; selecting the threshold width value based on the towing signal such that an enhanced threshold width value is employed when the vehicle is towing a trailer; and outputting a lane departure warning signal based on the processed images and selected threshold width value. - View Dependent Claims (9, 10, 11, 12, 13, 14)
