Description

Vehicle head lamp brightness and irradiation angle control device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for controlling a head lamp brightness and irradiation angle of a vehicle. In particular, the head lamp brightness and irradiation angle of a vehicle for adjusting the irradiation angle of the head lamp according to the traveling direction of the vehicle and further controlling the brightness of the head lamp. It relates to a control device. In general, the vehicle is equipped with a headlamp to light the front of the vehicle when driving on a dark road, the headlamp is lowered according to the driver's choice to operate as a downlight for illuminating the down and uplight for illuminating the upward direction. As a general rule, when driving at night, high beams interfere with the driving of other vehicles, so they are not often used, and mainly use low beams to illuminate the road.

However, the conventional headlamp as described above has a fixed light intensity, so that the driver cannot arbitrarily adjust the brightness of the headlamp according to the surrounding light and darkness, so that the driver who runs in a very dark place such as a tunnel can be used. In addition to causing inconvenience, sometimes there was a problem that the driver could not judge the lane correctly and caused a dangerous accident. Accordingly, the present invention is to solve such a problem, and automatically instructs the direction of the headlamp to the other vehicle by instructing the irradiation angle of the headlamp automatically according to the heading direction of the headlamp, and also according to the surrounding light and dark It is an object of the present invention to provide a head lamp brightness and irradiation angle control device for a vehicle that can automatically adjust the brightness of the head lamp.

Figure is a block diagram of a head lamp brightness and irradiation angle control device of a vehicle according to an embodiment of the present invention.

The head lamp brightness and irradiation angle control device of the vehicle of the present invention for achieving the above object is a head lamp control switch for automatically adjusting the irradiation angle and brightness of the head lamp and the front wheel angle detector for detecting the steering angle of the front wheels. And a head lamp actuator for operating the head lamp motor and the head lamp motor in the forward and reverse directions by rotating the head lamp motor left and right by forward and reverse rotation. In order to control the brightness of the head lamp, the brightness control unit for controlling the applied power intensity of the head lamp and the detection value input from the contrast detection unit when the head lamp control switch is turned on are compared with the previously stored reference value. On the basis of the front wheel angle detection value input to the sensing unit, the headlamp actuator and Also it characterized in that it comprises a control unit for controlling the control unit.

EXAMPLE

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

Referring to the drawings, the headlamp brightness and irradiation angle control apparatus of the vehicle of the present invention includes a front wheel angle detector (1) for detecting the steering angle of the front wheel and a contrast detector (2) for detecting the light and dark around the driving A brightness control unit 5 and a headlamp control switch for controlling the applied power intensity of the headlamp to adjust the brightness of the headlamp actuator 4 and the headlamp for operating the headlamp motor 3 in the forward and reverse directions ( 6) Compares the detected value input from the contrast detection unit 2 and the already stored reference value at turn-on, respectively, and determines the headlamp actuator 4 based on the determination result and the front wheel angle detection value. And a control unit 7 for controlling the luminance control unit 5. When the driver turns on the head lamp control switch 6 while driving, the direction of the vehicle is changed, and the front wheel angle detector 1 detects the steering angle of the front wheel and inputs the front wheel angle detection value to the fisherman 7. . Subsequently, the controller 7 determines the traveling direction of the vehicle based on the input front wheel angle detection value, and operates the head lamp actuator 4 to change the irradiation direction of the head lamp according to the determination result. The head lamp actuator 4 controls the irradiation direction of the head lamp by rotating the head lamp motor 3 in the forward and reverse directions according to the command of the control unit 7. In addition, when the head lamp control switch 6 is turned on while driving, the contrast detecting unit 2 detects the light and dark around the vehicle while driving and inputs the detected value to the controller 7, and the controller 7 inputs the contrast. The detection value is compared with the previously stored reference value, and the determination result is output to the luminance controller 5. Subsequently, the brightness controller 5 controls the applied power intensity of the head lamp according to the command of the controller 7 to adjust the brightness of the head lamp.

As described above, the headlamp brightness and irradiation angle control device of the vehicle of the present invention automatically instructs the irradiation angle of the headlamp in accordance with the traveling direction of the headlamp, and instructs another vehicle in the traveling direction, Accidents can be prevented in advance, and the brightness of the headlamps is automatically adjusted according to the ambient light and darkness, thereby providing an excellent effect for the convenience of the driver.
