Abstract

A headlight control device automatically switches a light distribution pattern of a headlight(11,12) for illumination ahead of a vehicle. The headlight control device including an imager(40) that sequentially takes images of a view ahead of the vehicle in a predetermined frame rate, an another-vehicle recognizer that recognizes a light source of another vehicle from each of the images sequentially taken by the imager, a light distribution controller(30) that switches the light distribution pattern according to a recognition result of the another-vehicle recognizer, and a signal provider(20) that provides a signal to illumination light of the headlight by causing the luminance of the headlight to change in a predetermined cycle. The another-vehicle recognizer recognizes, as reflected light of the headlight of the vehicle, a light source which is present within the image and of which luminance change is substantially similar to a luminance change of the signal.

Description

technical field

[0001] The present invention relates to a headlamp control device which detects the situation in front of the own vehicle and automatically switches the light distribution type, and more particularly relates to a device which can recognize the reflected light of the headlamp of the own vehicle from other light sources. Background technique

[0002] Generally, the headlights of vehicles such as automobiles can be switched between a driving beam (high beam) and a crossing vehicle beam (low beam), or can be turned off independently of the driving beam and the crossing vehicle beam.

[0003] In recent years, it has been proposed to automatically switch from high beam to close when the situation ahead of the host vehicle is recognized by cameras and radars, and when glare (glare) is detected. Light switching function (automatic high beam function).

[0004] As a prior art related to such automatic high beams, for example, Patent Document 1 describes the following...
