Apparatus and Method for Controlling Headlight}

The present invention relates to a headlight control, and more particularly, to a headlight control device and method that can change the irradiation direction of the headlight when left or right turn.

In general, the headlights installed on both sides of the front of the vehicle brightly illuminate the front of the vehicle so that the driver secures a forward watch when driving at night.

By the way, the conventional vehicle headlight is completely fixed to the front of the vehicle, so that only the front of the vehicle is illuminated. Therefore, when the vehicle travels on a curved road rather than a straight road, the traveling direction of the car and the irradiation direction of the headlight do not coincide, and thus the road surface to be driven cannot be reliably illuminated.

In order to solve this problem, there has been proposed a headlight that changes the direction of irradiation of the headlight in connection with the rotation of the heel or by using GPS information. However, the former heel linkage method was disadvantageous at the starting point of the curve road before the heel was rotated, and the latter method of using the GPS information could not be used in a vehicle without navigation, and in case of navigation or malfunction of the GPS satellite. There was a problem that could cause serious problems.

In order to solve the above problems, it is an object of the present invention to provide a headlight control apparatus and method that can reduce the risk factor by illuminating the surrounding road surface when left turn or right turn.

According to the present invention, the direction of the headlights is changed only when the handle is manipulated to evolve from a conventional headlight which cannot change the direction of the headlight at the beginning of the curve road, and thus the headlight at the beginning of the curve road with a high accident rate. Since the direction of investigation can be changed, the risk of accident can be greatly reduced.

In addition, the present invention can more accurately grasp the road situation to be changed even when changing lanes, and it is possible to easily determine that the surrounding cars are attempting to change lanes through the headlight irradiation direction, thereby reducing the risk of accidents. .

Hereinafter, a headlight control apparatus according to an exemplary embodiment of the present invention will be described with reference to FIG. 1. 1 is a block diagram showing a headlight control apparatus according to an embodiment of the present invention.

As shown in FIG. 1, the headlight control apparatus 10 according to the embodiment of the present invention includes a switch 100 and a controller 200.

The switch 100 may indicate the direction of rotation of the vehicle to the control unit 200 with respect to the right turn and the left turn of the car, respectively, and includes two buttons including a left turn button 110 and a right turn button 120. It is possible to instruct the right turn or the left turn at the time of each button operation, it is composed of a single button can indicate the right turn or left turn by the operation time or the number of operations.

The control unit 200 converts the irradiation direction of the right headlight and the left headlight, respectively, according to the right turn and left turn indication information by the switch 100. That is, the control unit 200 changes the irradiation direction of the right headlight to the right at the time of the right turn instruction of the switch 100, and irradiates the left headlight at the left rotation of the switch 100. Change direction to the left.

The controller 200 changes the irradiation direction of each headlight to the front when the handles are aligned even when the irradiation directions of the left headlight and the right headlight are switched.

On the other hand, even if the switch 100 is not operated, the headlight control device 10 is operated so that the indicator light on the left or right side is turned on, or when the handle is operated on the left or right side, The irradiation direction can be changed to left and right respectively.

In addition, the headlight control device 10 may adjust the change in the irradiation direction of the headlights in conjunction with the steering angle of the handle when the headlight control device 10 is linked with the handle.

Hereinafter, an application example of the headlight control device 10 according to an exemplary embodiment of the present invention will be described with reference to FIG. 2. 2 is a view showing a change in the irradiation direction of the headlights when the right turn by the headlight control device 10 according to an embodiment of the present invention.

As shown in FIG. 2, the headlight control apparatus 10 according to the exemplary embodiment of the present invention changes the irradiation direction of the right headlight by θ from the front to the right when the user rotates right according to a user's right turn button 120 manipulation. After the right turn is finished and the handle is aligned, it is changed from the right side to the front side.

Hereinafter, a headlight control method according to an exemplary embodiment of the present invention will be described with reference to FIG. 3. 3 is a flowchart illustrating a headlight control method according to an embodiment of the present invention.

Referring to FIG. 3, the headlight control apparatus 10 checks whether at least one of the direction indicator lamp, the headlight irradiation direction button, and the handle has been operated (S310).
