TRAILER LANE DEPARTURE WARNING SYSTEM |
摘要 |
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 an operator to provide trailer width information when the trailer detector indicates that the vehicle is towing a trailer. The lane departure warning system also includes a sensor for detecting a hitch angle between the vehicle and the trailer. A controller determines a lateral offset of the trailer relative to the vehicle based on the hitch angle and a length of the trailer for generating a warning signal when the lateral offset crosses the lane boundary. |

1. A lane departure warning system for a vehicle towing a trailer, comprising:
an imager detecting a lane boundary on a roadway; a sensor detecting a hitch angle between the vehicle and the trailer; a controller determining a lateral offset of the trailer relative to the vehicle based on the hitch angle and a length of the trailer; and a warning apparatus generating a signal when the lateral offset crosses the lane boundary. |
