LANE DEPARTURE WARNING DEVICE AND METHOD
First Claim
1. An apparatus for assisting driving of a host vehicle, comprising:
- an image sensor configured to detect lane lines of a traveling lane on which the host vehicle is traveling; and
a controller communicatively connected to the image sensor,wherein if the image sensor detects a vanishing region where one of lane lines of the traveling lane vanishes, the image sensor is configured to detect a distant lane line located opposite to the host vehicle with respect to the vanishing region, andthe controller is configured to;
determine whether the host vehicle enters into a road junction region based on information on the distant lane line; and
deactivate a lane departure warning if it is determined that the host vehicle enters into the road junction region.

Abstract
The present invention relates to a lane departure warning device or the like that limits a lane departure warning in a special road environment, in a case where it is confirmed that a driver has a lane departure intention, and so on. It is possible to secure the reliability of a lane departure warning system and to provide a driver'"'"'s convenience by limiting the lane departure warning in the case where the vehicle enters into a special road region, such as a road junction/branch region by comprehensively considering information captured by a camera of the vehicle, navigation map information, and so on while using a general lane departure warning, and also limiting the lane departure warning even in the case where the driver'"'"'s lane departure intention is confirmed.

6. An apparatus for assisting driving of a host vehicle, comprising:
-
an image sensor configured to detect lane lines of a traveling lane on which the host vehicle is traveling; and a controller communicatively connected to the image sensor, wherein if the image sensor detects an angled region where a first lane line of both lane lines of the traveling lane is angled in an outward direction, the controller is configured to;
determine whether the host vehicle enters into a road branch region based on information on a second lane line of the traveling lane; and
deactivate a lane departure warning if it is determined that the host vehicle enters into the road branch region. - View Dependent Claims (7, 8, 9, 10)
