Here, the text indicator 403 is for displaying the state of the road in letters, when the smooth communication of the road is a letter 'safe' is displayed.
On the other hand, based on the signal detected by the infrared detection unit 409, when the control unit 501 determines that the vehicle is in the stopped state at the current position, the control unit 501 sends the variable speed information to the display driver 503. to provide. The variable speed information is information to be displayed by the variable speed indicator 401. The variable speed information is a current vehicle driving speed and is displayed as '0 km / h' in this embodiment. In addition, the control unit 501 provides the current vehicle driving speed information to the communication unit 505, the communication unit 505, along with the unique code information of the corresponding fog induction lamp 201, the vehicle running speed information to the rear fog Transmit to induction lamp.
The fog guidance lamp installed at the rear recognizes that the vehicle driving speed information of the currently received fog guidance lamp is the nearest front fog guidance lamp based on the unique code information, and displays a variable speed for limiting the driving speed of the vehicle. As described above, the current fog induction lamp to display a speed limit of '10Km / h' through the speed guide display to prevent the crash of the rear vehicle. Of course, the fog induction lamp located behind the current fog induction lamp receives the speed limit indication information displayed from the front through the communication unit, and displays a speed limit of '30 km / h '. Through this same procedure, fog guidance lamps within a certain area located at the rear display a variable speed limit, and the vehicle driver is notified of continuous deceleration as the vehicle nears an accident point ahead.
Although the above described driving speed limit of the vehicle is made based on an accident point on the road, when the running speed of the vehicle is lowered according to the fog density detected by the fog detector 509, the fog is induced in the rear. Notify by lamp. That is, when the vehicle speed at the current position is '10Km / h', the fog guidance lamp located at the rear displays the speed limit of '30Km / h', and the fog guidance lamp located at the rear is 60Km / h. Display the speed limit. As such, a plurality of fog induction lamps maintain safety with each other by maintaining an organic relationship with road conditions.
On the other hand, the control unit 501 has a control pattern for reducing the power consumption of the system, which controls the brightness of the fog induction lamp 405 and the optical fiber light emitting unit 407, or control only the fog induction lamp 405 lighting consumption The amount of power that can be reduced can be reduced. Such a control pattern is to increase the operating performance of the fog induction lamp that is used urgently in the event of a fog or an accident, to facilitate the power supply of the hybrid power generation system described above.
The fog induction lamp 405 and the optical fiber light emitting unit 407 of the fog induction lamp applied in the present invention is set to a different signal, to visually indicate an accident occurrence or fog generation, etc. separately from the indication of the variable speed indicator 401 It can be recognized as For example, as illustrated in FIG. 6, when the fog is generated, the optical fiber light emitter 407 blinks at an appropriate amount of brightness to notify the driver of the fog occurrence and reduce power consumption. Of course, the blinking speed of the optical fiber emitter 407 may be increased according to the density of the fog, thereby increasing the notification effect.
On the other hand, the flashing of the fog induction light 405 is used as a means for notifying that the accident vehicle occurrence or congestion, the flashing of the optical fiber light emitting unit 407 may be used as a means for recognizing the road route at night. . 7 is a view showing an embodiment of the present invention.
