Abstract

The present invention relates to a LANE DEPARTURE AVOIDANCE ASSISTANCE DEVICE, a SEPARATOR DISPLAY METHOD, AND a PROGRAM. The lane departure avoidance assistance device comprises: a photography means for photographing a lane separator which separates driving lanes; a host vehicle location detection means for recognizing the lane separator from a photographed image data recognition region and detecting a host vehicle location in the width direction within the lane; a driving assistance means for carrying out driving assistance using the result of recognizing the lane separator; and a display means for displaying the result of recognizing the lane separator. The lane departure avoidance assistance device further comprises a recognition result display control means for displaying, if either the left or right white line is not recognized, the non-recognized lane separator in a display state which is not a display state which denotes non-recognition according to the host vehicle location.

Description

technical field [0001] The present invention relates to a lane departure prevention assisting device that recognizes a lane dividing line to assist in preventing departure from a lane based on the position of an own vehicle in a driving lane, and more particularly relates to a lane departure preventing assisting device that displays the recognition state of a lane dividing line. Background technique [0002] It is known to have a lane departure warning device (LDW: Lane Departure Warning) that predicts the departure from the lane and sounds an alarm by recognizing the white line by a vehicle-mounted imaging device and an image processing device, and applies a steering force for driving in the center of the lane. Lane Keeping Assist (LKA: Lane Keeping Assist). [0003] In LDW / LKA, the driver is usually notified of the current operating conditions (for example, refer to Patent Document 1). That is, this is because even if the LDW / LKA switch is on, the sound of the alarm and t...
