Description
The present invention relates to a device for driving a vehicle running speed using a sequential blinking method, and more particularly, to a device for driving a vehicle by using a sequential blinking method that induces deceleration and acceleration of a vehicle running speed, The present invention relates to an apparatus and a method for inducing a vehicle running speed using a method.
Generally, a driver of a vehicle is required to travel at a constant speed at a desirable speed when driving on the road. In particular, curved roads are required to decelerate at a fixed speed and to travel at constant speed because there is a limit to securing a forward view. In addition, in the case of a tunnel, it is difficult to secure sufficient illumination to recognize the space limitations and road conditions, And a significantly low visual guidance function due to changes in road surface or facilities, etc., are required for deceleration and constant speed running.
In order to solve such a problem, conventionally, various kinds of deceleration guide marking facilities such as a reflection light or a flashing light or various types of decelerating guide marking facilities are installed along the road at the center of the road so that the driver can recognize the road situation so that the road can be safely run . At this time, the reflection light reflects the light of the sunlight or the headlight of the vehicle to enter the driver's field of view, and the flashing light emits light by itself to allow the driver to check the light at night or in the tunnel. Is a representative example.
Also, apart from the visual guidance system, a speed camera and various warning, guidance signs, and stationary are installed and operated for the (insertion) driving speed deceleration or acceleration induction. However, this is a behavior inducing method based on recognition judgment, They tend not to be easily recognized or deliberately avoided.
In this way, the conventional flashing system for the sight guidance system (including the road delegator) installed at the road boundary is proposed for regular and stable blinking to clearly inform the driver of the road shape and the like.
However, the method of inducing the desirable driving speed through the blinking method is not considered. The technique of inducing the deceleration based on the wind speed according to the running of the vehicle is not limited to the malfunction due to the change in the wind speed other than the running of the vehicle, And there is a problem that consideration is not given to the case where acceleration is required.
In addition, speed cameras and various warning, guidance signs, and stationery are installed and operated for driving speed deceleration or acceleration induction. However, this is a behavior inducing method based on recognition judgment and is not easily recognized by the driver or is intentionally avoided There is a tendency.
Due to these problems, first, the tunnel section is required to have a safe running less than the specified speed under the road condition, compared to other road sections, and various warning, guidance signs, and warning signs as well as warning lighting facilities are installed. There is a problem that frequent accidents due to speeding in the tunnel occur frequently.
Second, in the section from the flat to the slope, the accelerator pedal must be stepped on in order to maintain the traveling speed. However, even though the traffic volume does not lead to congestion, there is no effective acceleration induction method based on the traffic volume at the sloping entrance section. There is a following problem.
Third, in the case of over-speed and over-speed, where the traffic volume is relatively low and the road condition is excellent (such as a wide road with a straight line) and overspeed more than the specified speed, A large traffic accident due to overspeed is repeatedly generated.
