A vehicle driving at night or in bad weather is generally turned on and running in order to secure a driver's field of view so that the driver can regard the current driver as a situation in which it is difficult for the driver to secure a field of view.

The roadside lamp control system according to an embodiment of the present invention is for controlling the streetlight using the illumination information of the vehicle in consideration of this point, and acquires the illumination information from the vehicle running on the section in which the streetlight to be controlled is installed , And the operation of the streetlight is controlled based on the obtained illumination information.

Meanwhile, as automobile-related technology develops, electronic control units (ECUs) are commonly used to control a large number of electronic devices and various convenience devices are integrated. The initial development objective of the ECU was to precisely control the core functions of the engine, but with the development of vehicle and computer performance, as well as the control of all parts of the vehicle, including the automatic transmission control, drive system, braking system and steering system .

The above-described technologies are applied for various control and communication inside the automobile. The roadside lamp control system and the control method according to the present invention are characterized by using illumination information of a vehicle.

This will be described in detail with reference to FIG.

First, the vehicle information receiving unit 20 receives vehicle information from a vehicle that runs on a section where a streetlight to be controlled is installed. Here, the vehicle information may be understood to include all kinds of information related to controlling and operating the vehicle as described above.

Communication between the traveling vehicle and the vehicle information receiver 20 can be performed using Wireless Access in Vehicular Environments (WAVE) or Dedicated Short Range Communications (DSRC).

At present, the most active ITS (Intelligent Transport System) wireless communication is DSRC, and domestic ITS services such as automatic fare collection and bus information system are provided using DSRC. In case of wireless DSRC, transmission speed of up to 1Mbps is supported in communication area of 100m or less.

WAVE is a next-generation ITS wireless communication that provides vehicle-to-vehicle communication and vehicle-to-vehicle communication at up to 54 Mbps, and supports inter-vehicle ad-hoc networks that were not present in existing DSRCs.

On the other hand, the illumination information extracting unit 30 extracts illumination information necessary for the streetlight control from the vehicle information acquired by the vehicle information receiving unit 20. The roadside lamp control system according to the present invention uses the state of the headlights and the taillights among the illumination information of the vehicle, which will be described in more detail in Fig.

On the other hand, the streetlight control unit 40 controls lighting of the street lamp to be controlled based on the state of the headlight and the taillight of the vehicle acquired by the illumination information extracting unit 30.

The control target streetlight may be a plurality of streetlights installed in the vicinity of the vehicle to be driven, and the number of streetlights to be controlled may be adjusted in consideration of the variables such as the average speed and the traffic volume of the vehicles under running.

2 is a table showing the streetlight control according to the illumination state of the vehicle.

Referring to FIG. 2, the streetlight control unit 40 controls the streetlight according to the state of the headlight and the taillight of the vehicle. When the tail lamp and the headlight of the vehicle are both off, When both the taillight and the headlamp are turned on, all of the surrounding streetlamps are turned on. When the taillight is turned on and the headlamp is off, Can be turned on.

It is possible to judge that there is no difficulty in securing the field of view necessary for driving even when the lighting is not turned on when the vehicle is turned off, As shown in Fig. 2, it is possible to control all lights to be turned off or all lights to be controlled.

In addition, when the headlight is turned off but the taillight is turned on, it is preferable that the controlled streetlight be lit up. On the other hand, FIG. 2 illustrates a case in which only the tail lamps are turned on among the tail lamps and the headlamps. However, it is also possible to control the headlamps and the headlamps in other ways on the assumption that only the headlamps are turned on. It is also possible to control the streetlight to further reflect the information about the streetlight.

On the other hand, the streetlight control unit 40 uses the illumination information of a plurality of vehicles traveling in the controllable streetlight installation section, and when the illumination of the vehicles of more than the majority is on or off, It can be determined that the illumination of the light source is on or off.

Vehicles running on the road can turn the lights on or off according to the driver's choice even if they run in the same weather condition or the same time zone. It is often necessary to extract the respective lighting information from a plurality of vehicles and reflect them all on the streetlight control Operation can be a hassle to the system and can make it difficult to perform reliable control.

Therefore, it is preferable that the lighting information is extracted from a plurality of vehicles traveling in a predetermined section, and in a case where a vehicle having more than a large number of vehicles turns on the headlights, it is preferable that all the vehicles traveling in the section are determined to turn on the headlights, This is the same for taillamps.

When the streetlight is controlled by extracting the illumination information from a plurality of vehicles, the illumination information until the total number of vehicles traveling in a certain section becomes equal to or greater than a predetermined number is used, or the section is traveled for a predetermined time A method of extracting illumination information from a vehicle may be used.

Fig. 3 is a schematic view showing a case in which the streetlight is lit up. Fig.

Fig. 3 shows a situation in which the streetlight to be controlled is turned on in full-on. As shown in Fig. 2, in the case where the lamp is turned on in full-on, only the tail lamp is turned on.

On the other hand, depending on the situation, it is also possible to use a method of lighting one street lamp for each street lamp in addition to the method for lighting the street lamp at a large number, and it will be obvious to a person skilled in the art that the street lamp can be controlled in accordance with the illumination information extracted from the vehicle information .

3, it can be seen that the vehicle information receiving unit 20 is shown. The vehicle information receiving unit 20 may be a roadside station (Road Side Station or Road Side Equipment) ).

The communication between the vehicle and the vehicle information receiving unit 20 can use WAVE or DSRC as described above. However, since WAVE and DSRC have differences in the communication radius, when WAVE is used, the vehicle information can be received over a wider range than when using DSRC.

4 is a schematic view showing a configuration of a roadside lamp control system 100 'according to another embodiment of the present invention.

The roadside lamp control system (100 ') further includes a determination unit (10) for determining whether an automatic light sensor is in operation of a vehicle traveling in a streetlight installation zone to be controlled, and the vehicle information receiver (20) The light sensor can receive vehicle information only for the vehicle in operation.

The automatic light sensor is a sensor used in an automatic light control (ALC) system. The ALC system automatically turns on or off tail lights and headlamps according to the ambient brightness. It is a system that automatically controls the lighting without any special operation by the driver when the ambient illumination is low due to fog, rain, snow or the like.

As described above, depending on the driver, there may be cases in which the driver does not perform appropriate lighting control in spite of the surrounding situation, or performs a different operation from the majority of other drivers. In this case, it is preferable to extract the illumination information by receiving the vehicle information only for the vehicle using the automatic light sensor, rather than collecting the information necessary for the streetlight control in all the vehicles.
