Vehicle rear side warning device

Abstract

A vehicle rear side warning device includes: a rear side image capturing unit that captures an image of a rear side of a vehicle; a detection distance calculation unit that calculates a rear detectiondistance based on the vehicle speed detected by the vehicle speed detection unit and the side space information detected by the side space detection unit; a moving body detection unit for extractingan image region for detecting a moving body to be passed between the vehicle and the side obstacle from the rear side image captured by the rear side image capture unit on the basis of the detection distance calculated by the detection distance calculation unit, and detecting the moving body from the extracted image region; and an alarm output determination unit that determines whether to notify an alarm to a driver of the vehicle on the basis of the moving body detection information detected by the moving body detection unit.

Description

Technical field [0001] The present application relates to a lattice alarm device for a vehicle. Background technique [0002] In the past, there was a rear side-side alarm device (so-called blind spots alarm system (BSW) or a warning system (LCW) that was used to identify adjacent lanes adjacent to the driving lane that was driving with this vehicle A. Subsequent vehicle B traveling, and when the vehicle A is changed, the subsequent vehicle B in the adjacent lane in the variability is driving, and the alert notification of the collision is possible to prevent the driver. The car A has collided with the subsequent vehicle B when the cavity is changed. [0003] For example, the following is disclosed in the vehicle monitoring device of Patent Document 1: The distance threshold is set according to the subsequent vehicle B traveling on the rear side of the vehicle A and the lateral distance of the vehicle A. When the distance between the A and the subsequent vehicle B becomes the dis...

Problems solved by technology

[0007] However, the conventional vehicle monitoring devices disclosed in Patent Document 1 or Patent Document 2 involve monitoring the vehicle running behind the vehicle A on the adjacent lane adjacent to the driving lane in which the vehicle A is driving. B means of detection not designed to detect a vehicle C, for example a two-wheeled vehicle, traveling in such a way as to pass between the host vehicle A and a vehicle B traveling in an adjacent lane

[0008] Therefore, even if the vehicle monitoring device described in the above-mentioned Patent Document 1 is used, there will be the following problem: it is difficult to set the distance threshold value according to the vehicle A and the vehicle B near the vehicle A, so as to estimate the possibility of collision. A vehicle C, for example as a two-wheeler, is detected for a higher vehicle C passing between the own vehicle A and the vehicle B driving in the adjacent lane.

In addition, there is a problem that warnings to vehicle B often occur, and the driver considers the warning to be too troublesome, so that the warning output of the vehicle monitoring device is stopped, so that it cannot be effectively utilized.

[0009] In addition, even in the monitoring device for a vehicle described in Patent Document 2, the same problem as described above also exists. In an environment where the vehicles B are traveling between each other, there is no problem in detecting the vehicle B, but since the vehicle B is often detected even if the vehicle C, for example, a two-wheeled vehicle is to be detected, subsequent detections will be performed. Actions limited to the vicinity

Therefore, there is a problem that detection cannot be performed sufficiently for the vehicle C, which is, for example, a two-wheeled vehicle, to notify the driver of an accurate warning corresponding to the vehicle C that is likely to come into contact or collide.
