Problems solved by technology

On the other hand, when the recognition accuracy of the driving lane line recognized from the image is low, the deviation between the long-distance white line shape obtained by estimation and the actual white line shape increases.
Under such circumstances, as a result of detailed analysis by the inventors, it was found that there is a possibility that the controllability of the vehicle running control based on the shape of the driving lane line may decrease.

no. 1 Embodiment approach

[0016] Hereinafter, the lane marking recognition device according to the present embodiment will be described with reference to the drawings. The lane marking recognition device of this embodiment is a device mounted on a vehicle. This lane line recognition device recognizes white lines that are running lane lines that define a driving lane of a vehicle. Information related to the white line recognized by the lane line recognition device (for example, white line information) is used to follow the preceding vehicle which is a vehicle traveling in the same lane as the own vehicle among the preceding vehicles driving in front of the own vehicle. Driving assistance control such as the adaptive cruise control of the vehicle, the lane keeping assist which controls the driving of the vehicle so that the vehicle does not deviate from the driving lane line. First, use figure 1 A schematic configuration of the lane marking recognition device according to this embodiment will be descri...

Abstract

A section-line recognition device (10) is applicable to a vehicle installed with an image-capturing device (21) for capturing images in front of the vehicle. The section-line recognition device (10) is provided with: a section-line recognition unit (11) for recognizing, on the basis of images acquired by the image-capturing device (21), travel section lines for dividing vehicle travel lanes; and a section-line estimation unit (12) for estimating, on the basis of the travel section lines recognized by the section-line recognition unit (11), the shape of travel section lines of such scope as to be incapable of being recognized by the section-line recognition unit (11). The section-line recognition device (10) determines the reliability of the travel section lines recognized by the section-line recognition unit (11), and invalidates the estimate of the shape of the travel section lines by the section-line estimation unit (12) on the basis of the determination result.

Description

[0001] This application is based on the Japanese application number 2015-009775 for which it applied on January 21, 2015, claims the priority of this application, and incorporates the whole content of this patent application into this specification by reference. technical field [0002] The present invention relates to a lane marking recognition device, in particular, to a lane marking recognition device suitable for a vehicle equipped with an imaging device for photographing the front of the vehicle. Background technique [0003] As driving assistance control of a vehicle, there is known an adaptive cruise control system that selects a vehicle traveling in the same lane as the host vehicle as the preceding vehicle and tracks the movement of the selected preceding vehicle, and that the vehicle does not deviate from the left and right driving directions. Various controls such as lane keeping assist to control the driving of the vehicle based on lane markings. [0004] In such...
