Title:
HEADLIGHT CONTROL DEVICE, HEADLIGHT CONTROL SYSTEM, AND HEADLIGHT CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2020/250746
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a headlight control device that allows recognition of a preceding vehicle by a vehicle-mounted camera without dazzling the driver of the preceding vehicle even at night. A headlight control program 200 has: a sequence control unit 201 that generates a headlight control signal from an image captured by a camera mounted on a vehicle; and a control value calculation unit 202 that calculates a control value for a light distribution pattern in the headlight control signal. An image recognition program 300 has a license plate recognition unit 302 that detects the license plate of the preceding vehicle from the image and a cut-off line recognition unit 305 that detects the cut-off line of a headlight from the image. A control value calculation unit 202 calculates the control value of the light distribution pattern so that the cut-off line detected by the cut-off line recognition unit 305 is located at a predetermined height above the upper end of the license plate detected by the license plate recognition unit 302.
