Vehicular lane monitoring system utilizing front and rear cameras
First Claim
1. A lane monitoring system deployed on a vehicle for monitoring the position of the vehicle relative to a lane in which the vehicle is traveling, the system comprising:
- a front camera mounted on the vehicle for capturing front lane image data relating to an area substantially to the front of the vehicle;
a rear camera mounted on the vehicle for capturing rear lane image data relating to an area substantially to the rear of the vehicle;
a processor coupled to said front camera and said rear camera for receiving said front lane image data and said rear lane image data, said processor configured to determine the position of the vehicle relative to the lane from (1) said front lane image data if said front camera is operational, and (2) said rear lane image data if said front camera is not operational and said rear camera is operational.

Abstract
A lane monitoring system deployed on a vehicle is provided for monitoring the position of the vehicle relative to a lane in which the vehicle is traveling. The system comprises a front camera for capturing front lane image data relating to an area substantially to the front of the vehicle and a rear camera for capturing rear lane image data relating to an area substantially to the rear of the vehicle. A processor is coupled to the front camera and the rear camera and is configured to receive the front lane image data and the rear lane image data. The processor is further configured to determine the position of the vehicle relative to the lane boundary from (1) the front lane image data when the front camera is operational, and (2) the rear lane image data when the front camera is not operational and the rear camera is operational.

11. A method for monitoring the position of a vehicle relative to a lane in which the vehicle is traveling, the vehicle including a processor, a front camera, and a rear camera, the method comprising:
-
capturing front lane image data relating to an area substantially to the front of the vehicle with the front camera;
capturing rear lane image data relating to an area substantially to the rear of the vehicle with the rear camera;
determining the position of the vehicle relative to the lane with (1) front lane image data when the front camera is operational, and (2) rear lane image data when the front camera is not operational. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A lane monitoring system deployed on a vehicle for monitoring the position of the vehicle relative to a lane in which the vehicle is traveling, the system comprising:
-
a front camera mounted on the vehicle for capturing front lane image data relating to an area substantially to the front of the vehicle;
a rear camera mounted on the vehicle for capturing rear lane image data relating to an area substantially to the rear of the vehicle;
a vehicle heading correction means for directing the vehicle;
an alert generator; and
a processor coupled to said front camera, said rear camera, said vehicle heading correction means, and said alert generator, said processor configured (1) to generate an alert when the vehicle is out of lane position by more than a first predetermined amount, the lane position being derived from said front lane image data when said front camera is operational and from said rear lane image data when said front camera is not operational, and (2) to perform a vehicle heading correction when the vehicle is out of lane position by more than a second predetermined amount, the lane position being derived from said front lane image data and said rear lane image data. - View Dependent Claims (19, 20)
