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 the image sensor is configured to, in response to detection of a vanishing region where one of lane lines of the traveling lane vanishes, detect a distant lane line located opposite to the vanishing region with respect to the host vehicle, andthe controller is configured to;
determine whether the host vehicle enters into a road junction region based on information on the distant lane line located opposite to the vanishing region; and
deactivate a lane departure warning in response to determination 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 the controller is configured to;
in response to the image sensor'"'"'s detecting an angled region where one lane line of both lane lines of the traveling lane is angled in an outward direction, determine whether the host vehicle enters into a road branch region based on information on an other lane line of the traveling lane; and
deactivate a lane departure warning in response to determination that the host vehicle enters into the road branch region. - View Dependent Claims (7, 8, 9, 10)

11. A method for assisting driving of a host vehicle, comprising:
-
detecting lane lines of a traveling lane on which the host vehicle is traveling by using an image sensor; detecting a vanishing region where one of lane lines of the traveling lane vanishes by using the image sensor; detecting a distant lane line located opposite to the vanishing region with respect to the host vehicle by using the image sensor; determining whether the host vehicle enters into a road junction region based on information associated with the distant lane line located opposite to the vanishing region with respect to the host vehicle; and deactivating a lane departure warning in response to determination that the host vehicle enters into the road junction region. - View Dependent Claims (12, 13, 14)
