On the other hand, the cameras for controlling violation of the regulations of the vehicles are frequently installed on the road. Typically, the cameras can perform tail wagging, stop line violation, illegal U-turn control, and speed limit violation.

In particular, in the case of a speed limit violation, a speed detection by a loop detector has been performed in the past. In such a speed detection by the loop detector, there is a problem that a maintenance cost due to road breakage and disconnection is excessively consumed. There is a problem that the purchase and installation cost is high, the influence of time and weather change is large, and the method using the Doppler effect has a problem of occurrence of error.

In order to solve the above problem, there is a demand for a system for collecting and storing speed data in a vehicle itself for a preset interval, and efficiently transmitting stored data to infrastructure equipment to determine and manage speed violation.

6A and 6B are flowcharts for explaining a speed violation interrupting process according to the present invention. FIG. 7 is a flowchart illustrating a process for selecting a speed violation interrupting process according to the present invention. FIG. 9 shows an example of a road traffic situation using data stored in the collected vehicle. FIG. 9 is a flow chart for explaining a speed violation interrupt process when there is a violation target section.

Referring to FIGS. 5A and 5B, when selecting a speed infringement target section, the start and end points of a speed infringement target section are selected using GPS data. As an example, in the case of a highway, since the violation speed between the IC and the JC is different, the start point and the end point can be selected based on the section in which the violation speed is different. As another example, in the case of a special section, a special management section such as a long bridge, a pole tunnel, a risk of overspeed accident, and a lot of accidents can be selected, and the start and end points of the region can be selected using GPS data.

The GPS data of the start point and the end point of the selected speed violation target section are stored in the memory 140 in the vehicle (S110).

When the vehicle passes through the pre-stored point A (S120), the OBD starts collecting the speed history information (S130). At this time, whether or not the vehicle has passed the pre-stored time point A is determined by using the GPS data in the vehicle, and it is determined whether or not the GPS data is stored in the memory 140. The OBD continuously collects the speed history information, and the time unit of the collection time may be 0.01 second.

When the vehicle passes through the end point B (S140) where the vehicle is currently stored, the OBD stops collecting the speed history information (S150). At this time, whether or not the vehicle has passed the pre-stored end point B is determined to be coincident with the GPS data stored in the memory 140 by using the GPS data in the vehicle.

When the vehicle meets the infrastructure equipment 200 during operation, the OBD transmits the speed history information collected in the infrastructure equipment 200 (S160). In this case, the collected speed history information is the speed history information collected from the point A to the end point B, and the speed history information is preferably transmitted through the WAVE.

After receiving the speed history information from the OBD, the infrastructure equipment 200 transmits the speed history information to the server 300 (S170). In this case, the transmitted information may include information of the vehicle itself in addition to the speed information of the vehicle.

The server 300 determines whether the speed of the vehicle 100 is violated in a specific section using the received speed history information and GPS data. That is, whether the speed of the detected vehicle 100 exceeds the speed of violation (S180). If the speed of the vehicle 100 is a speed violation, information on the vehicle having exceeded the speed of violation may be transmitted to a predetermined facility (S190) so that the speed limit violation interruption can be performed. At this time, the predetermined organization may include an organization that gives penalties and fines in accordance with the control of the vehicle, and an organization that sends the information related to the regulation to the borrower.

Referring to FIG. 7, when the OBD collects the speed history information (S130) and the vehicle passes through the other time point C1 (S131) where the vehicle is stored during the driving, the OBD adds the additional speed history Information is collected (S132). Thereafter, when passing through the end point B (S140), the OBD stops collecting the speed history information (S150), and transmits the speed history information collected by the OBD to the infrastructure equipment (S160).

In addition, the vehicle 100 collects information on the vehicle through the OBD while driving, and also collects information on the road traffic situation. The server 300 can transmit the information to the server 300 through the infrastructure device 200. The server 300 can determine the traffic conditions of the road using the collected information,

Referring to FIG. 9, using the GPS and the speed data recorded in the OBD of the vehicle 100, driving habits (for example, rapid acceleration, rapid deceleration, curve driving habits, etc., And can reduce the occurrence of accidents by processing and providing them to the user.

The present invention can also be embodied as computer-readable codes on a computer-readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may be implemented in the form of a carrier wave (for example, transmission over the Internet) .

In addition, the computer-readable recording medium may be distributed over network-connected computer systems so that computer readable codes can be stored and executed in a distributed manner. In addition, functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers of the technical field to which the present invention belongs.

It should be understood that the above-described apparatus and method are not limited to the configurations and methods of the embodiments described above, but the embodiments may be modified such that all or some of the embodiments are selectively combined .
