Problems solved by technology

As a result, the reflector emits light again, so that the headlamp is rotated repeatedly so that the irradiation range is avoided from the reflector in a direction away from the vehicle in front, etc., and the phenomenon of uneven speed regulation occurs, which is annoying.
[0008] In addition, compared with the low beam, the intermediate high beam not only brightly illuminates the distant place, but also brightly illuminates the nearby parts, so you can clearly know that the irradiation range of the street tree or the soundproof wall is moving, and you will feel annoyed.

Embodiment Construction

[0024] Below, refer to Figure 1 to Figure 8 , the vehicle headlamp device according to the embodiment of the present invention will be described. like figure 1 As shown, a vehicle headlamp device 1 includes an on-vehicle imaging device 2 , a steering angle sensor 3 , a wheel speed sensor 4 , an ECU (Electronic Control Unit) 5 , and headlamps 6 and 7 .

[0025] The vehicle-mounted camera 2 is installed inside the front window of the vehicle, takes pictures of the front of the vehicle, and sends the data to the ECU 5 . The steering angle sensor 3 is an existing sensor provided for ESC (Electronic Stability Control: Electronic Stability Control, anti-skid device), and is provided in a steering mechanism. The steering angle sensor 3 detects the steering angle of the vehicle, and sends a steering angle signal indicating the detection result to the ECU 5 . The wheel speed sensor 4 is an existing sensor provided for an ABS (Anti-lock Braking System). The wheel speed sensor 4 det...

Abstract

The present invention relates to a headlight device for a vehicle. The headlight device for a vehicle includes: a headlight that illuminates the front of the vehicle; an irradiation range changing unit that changes the irradiation range of the headlight; a position of a vehicle in front that exists in front of the vehicle; a control unit that controls the irradiation range changing unit based on the position of the vehicle in front detected by the detection unit; and a determination unit that determines whether the position of the vehicle in front is within the irradiation range, in If it is determined that the position of the vehicle ahead is within the irradiation range, the irradiation range is changed so that the position of the vehicle ahead is outside the irradiation range; The unit performs control to suppress changes in the irradiation range.

Description

technical field [0001] The present invention relates to a vehicle headlamp device. Background technique [0002] In the past, in order to improve the safety of vehicles when driving at night, AFS (Adaptive Front-Lighting System: Adaptive Front-Lighting System, variable light distribution front lighting system) is known, which controls the direction of the optical axis of the headlight according to the steering direction of the steering wheel. lamp). [0003] And, in addition to this, there is known a high beam variable headlamp system (Adaptive Driving Beam System: Adaptive High Beam System), that is, by using a part that shields the vehicle in front (the preceding vehicle or the oncoming vehicle) to illuminate with high beam The other part of the light distribution pattern called the middle high beam performs image processing on the information from the vehicle-mounted camera to detect the position of the vehicle in front and follow the light-shielding part without giving ...
