The present invention relates to a vehicle tracking method and an apparatus for implementing the same. More specifically, the present invention relates to a method for easily tracking a vehicle that has escaped after a traffic accident using driving information and an apparatus for implementing the same.

Automobiles are becoming a necessity in modern society. For example, the number of registered vehicles in Korea has already exceeded 15 million vehicles as of February 2005, and the number of traffic accidents caused by the increase of vehicles is also increasing. In particular, when there were no witnesses after a car accident, the hit-and-run traffic accident that escaped without being reported was highlighted as a social problem.

According to the statistics of the Korea National Statistical Office, more than 15,000 hits per year occurred between 1990 and 2005, resulting in 600 deaths each year and 20,000 injuries. The problem is that the victims and their families continue to suffer from both the psychological pain of hit and run and the economic burden of not being able to compensate for the accident.

In fact, the hitchone traffic accident has no witnesses, and even if there are any witnesses, it is impossible to check the license plate number. Accordingly, the Korean National Police Agency recently made a database of major auto parts, auto maintenance, and parts companies to track suspect vehicles based on parts or tire traces of accident vehicles left at the accident site in the police computer network. There are many questions about its effectiveness.

In addition, Korean Patent Laid-Open Publication Nos. 1997-0041951 and 2001-0059434 include a shock sensor and a signal generator connected to the shock sensor in a vehicle, and automatically transmit information about the accident vehicle by the impact generated during a traffic accident. By doing so, techniques are disclosed for a device capable of tracking an accident vehicle. However, accident vehicle tracking device technologies such as 1997-0041951 and 2001-0059434 rely on the shock sensor only to determine whether an accident occurs, and there are problems in that it is not practical to distinguish a hit-and-go traffic accident.

A first object of the present invention for solving the above problems is to provide an accident vehicle tracking method that can easily track the accident vehicle using the driving information of the vehicle, thereby greatly improving the arrest rate for the hit suspect.

It is a second object of the present invention to provide an apparatus for implementing the aforementioned accident vehicle tracking method.

The first information is transmitted to a first vehicle group selected using a wireless communication method. Subsequently, the transmitted first information is compared with information stored in each of the vehicles belonging to the first vehicle group. As a result of the comparison, second information wirelessly transmitted by the second vehicle group including the accident vehicle that matches the first information is obtained. Here, when the second information does not satisfy the preset criterion, the above-described steps may be repeatedly performed by using information different from the first information.

According to embodiments of the present disclosure, the accident vehicle may include a vehicle that has escaped after causing a traffic accident, and the first information may include GPS coordinates of the point where the accident occurred and a time zone in which the accident occurred. In addition, the first vehicle group may include all vehicles within a specific area, and the second information may include GPS coordinates, a vehicle number, or driver information of the accident vehicle.

The accident vehicle may include a stolen vehicle, and the first information may include a unique number of the accident vehicle.

According to another aspect of the present invention, an accident vehicle tracking apparatus includes a driving information unit mounted on a vehicle, connected to the driving information unit, and transmitting and receiving information of the vehicle to and from the outside using a wireless communication method. And a second transmission / reception unit connected to the operation information unit and the wireless transmission / reception unit, and comparing the first information received from the outside with the second information stored in the operation information unit, and similar to the first information from the second information. And an identification unit for detecting information, and a control unit connected to the identification unit and the wireless transmission / reception unit and controlling to transmit information detected by the identification unit to the outside via the wireless transmission / reception unit.

According to embodiments of the present invention, the driving information unit may include a GPS unit for acquiring position information for each time zone of the vehicle, an operation unit for acquiring control system information installed in the vehicle, and the information of the GPS unit and the operation unit. It may include a storage unit for storing.

The apparatus may further include a portable terminal connected to the driving information unit in a short range wireless communication method or a wired communication method to read the second information.

As described above, by using the location of the accident occurrence point and the accident occurrence time zone information when the hit hit a traffic accident, it is possible to check the vehicles for hit cars at the position at the time, and to track the positions of the vehicles in real time. Therefore, it is possible to easily arrest the accident vehicle that caused the hit-off traffic accident.

Hereinafter, a method and apparatus for tracking an accident vehicle according to preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments, which are common in the art. Those skilled in the art will be able to implement the invention in various other forms without departing from the spirit of the invention.

How to track an accident vehicle

1 is a schematic flowchart illustrating an accident vehicle tracking method according to an embodiment of the present invention.

Referring to FIG. 1, first, first information about an accident vehicle is obtained (S110). In the case of a hit-one-car traffic accident, the first information can be easily collected by the reporter who passed the scene, or by a police officer or a forensic investigation team. Here, the first information includes an accident occurrence location and a time zone in which the accident occurred. The accident location may be any location information such as a road name, address or GPS coordinates, but GPS coordinates capable of precisely displaying the location are preferred.

When it is difficult to know the exact time of the accident, the accident occurrence time can be estimated based on evidence found in the traffic accident site survey, for example, victims, damages, tire marks, and the like. Accordingly, the collected information may be transferred to a communication network such as a police accident situation room to obtain first information including an accident occurrence location and a time zone.

Next, the first information is transmitted to the first vehicle group selected by using a wireless communication method (S120). First, the first vehicle group may be selected based on a region. For example, the first vehicle group may be selected from all vehicles in the country. In this case, the first information may be transmitted to the whole country through a wireless communication network, and the first information may be received using a wireless transceiver connected to an accident vehicle tracking device such as a GPS black box mounted in all vehicles.

Alternatively, the first vehicle group may be limited to all vehicles existing in a specific region according to the content of the first information, or may be limited to a specific vehicle type, for example, a passenger vehicle moving in a specific region, for example, Seoul. have.

Subsequently, the transmitted first information is compared with information stored in each of the vehicles belonging to the first vehicle group (S130). For example, the identification unit mounted on the vehicle can search for information that matches the first information within the information stored in the vehicle. For example, it may be determined whether a distance between a location where a traffic accident occurs and a location stored in vehicles of the first vehicle group in a traffic accident time zone falls within a preset error range. The position is preferably represented by GPS coordinates that can be accurately displayed.

Finally, the second information wirelessly transmitted by the second vehicle group including the accident vehicle in the first vehicle group is acquired (S140). For example, when information matching the first information is detected in the information of the vehicle, the information is automatically transmitted to the situation room through the wireless transmission / reception unit. As a result, the situation room acquires second information including driving information corresponding to the first information, a vehicle number of the vehicle, driver information, and real-time location information of the vehicle. For example, the driving information may include driving speed and deceleration and acceleration of a vehicle, brake operation, movement of a handle and an airbag, and the like.

Accordingly, the situation room may detect the suspect vehicle among the vehicles of the second vehicle group by comparing and analyzing the obtained second information with the traffic accident scene data. Further, since the vehicle can be tracked in real time through the driving information unit mounted in the suspect vehicle and the radio transceiver, the vehicle can be tracked in real time through the location information of the suspect vehicle, for example, GPS coordinates, thereby facilitating the traffic accident suspect. You can be arrested.

However, in the case of a hit-and-run traffic accident, it is difficult to grasp the exact time at which the traffic accident occurred, and a large number of suspect vehicles suspected as an accident vehicle are detected and these vehicles constitute the second vehicle group. For example, in the first information, the accident occurrence time zone may be generally formed at an interval of 30 minutes or more, so that all vehicles passing through the accident occurrence time period at the accident occurrence position form the second vehicle group. However, the number of vehicles forming the second vehicle group may be greatly reduced according to the information collected at the traffic accident site.

That is, when the second information is insufficient, the suspect vehicle can be more easily detected by repeatedly performing the above steps S110 to S130. Specifically, when it is difficult to determine the suspect by the second information wirelessly transmitted by the second vehicle group, third information different from the first information about the accident vehicle is obtained. For example, the third information may include more detailed information collected by an eyewitness, a police officer or a forensic investigation, a vehicle type obtained by a CCTV installed near an accident point, a vehicle color, a part of a driver's gender or a vehicle number. It may be more detailed information. Then, the third information is transmitted back to the third vehicle group using a wireless communication method. The third vehicle group may be the first vehicle group, the second vehicle group, or any newly selected vehicle group.

Next, the fourth information transmitted wirelessly by the fourth vehicle group including the accident vehicle in the third vehicle group by comparing the transmitted third information with driving information stored in each of the vehicles belonging to the third vehicle group. Obtain information. For example, the third information is compared with driving information stored in a vehicle constituting the third vehicle group, and when the matched information is detected in the driving information, the third information is automatically sent to the situation room through the wireless transmission / reception unit. do. Accordingly, the situation room may include driving information corresponding to the third information, vehicle number of the vehicle, driver information, real-time location information of the vehicle, and the like, from the driving information stored in each of the vehicles belonging to the third vehicle group. 4 Information is obtained. Accordingly, since the fourth vehicle group may be configured with fewer vehicles than the vehicles of the second vehicle group, the time taken to arrest the suspect can be greatly shortened.

Accident vehicle tracking device

2 is a schematic configuration diagram illustrating an accident vehicle tracking apparatus according to a preferred embodiment of the present invention.

Referring to FIG. 2, the accident vehicle tracking apparatus 100 includes a driving information unit 110 mounted in a vehicle, a wireless transmission / reception unit 120 connected to the driving information unit 110, and the driving information unit ( 110 and an identification unit 130 connected to the wireless transmission / reception unit 120, and a control unit 140 connected to the identification unit 130 and the wireless transmission / reception unit 120.

The driving information unit 110 is preferably installed in the vehicle so as to be connected to the control system of the vehicle. Accordingly, the driving information unit 110 may perform a function of recording and storing all driving histories of the vehicle such as position information for each time zone of the vehicle, driving speed, deceleration and acceleration, brake operation, movement of a steering wheel and airbag, and the like. have. For example, the driving information unit 110 is connected to a GPS unit 112 for receiving GPS coordinates of the vehicle from a GPS satellite and a control system of the vehicle, and processes vehicle information transmitted from the vehicle control system. And a storage unit 116 connected to the GPS unit 112 and the operation unit 114 to record all the information generated from the GPS unit 112 and the operation unit 114. have.

The wireless transmission / reception unit 120 is connected to the driving information unit 110, and transmits and receives information of the vehicle with the outside using a wireless communication method. For example, the wireless transmission / reception unit 120 may transmit / receive information with a situation room such as a police accident situation room by using an existing wireless base station. The wireless communication method may use a wireless communication method such as a code division multiple access (CDMA) method, a time division multiple access (TDMA), and a wibro to transmit a large amount of information at a high speed. However, the present invention is not limited to the wireless communication scheme described above.

The identification unit 130 is connected to the driving information unit 110 and the wireless transmitting / receiving unit 120 and stores first information received from the outside and information stored in the storage unit 116 of the driving information unit 110. Compare and detect information similar to the first information from the stored information. For example, the identification unit 130 performs a function of comparing the location of the accident time zone and the location of the accident point received from the situation room by the vehicle stored in the storage unit 116 in the accident time zone. .

The control unit 140 is connected to the identification unit 130 and the wireless transmission and reception unit 120, and controls to transmit the information detected by the identification unit 130 to the outside through the wireless transmission and reception unit 120. do. Specifically, the comparison result performed by the identification unit 130 is input to the control unit 140, the control unit 140 transmits the result of the second information of the vehicle to the situation room. Here, the second information may include driving information of the vehicle that corresponds to the first information, that is, GPS coordinates of the vehicle, vehicle number of the vehicle, driver information, and real-time GPS coordinates during an accident time zone.

Preferably, the control unit 140 may selectively transmit the information of the vehicle by comparing the comparison result with a preset error range. For example, when the distance between the position of the accident vehicle and the position of the vehicle receiving the first information is within an error range during the accident time, the vehicle is determined as a preliminary suspect vehicle and the second information of the vehicle is wirelessly determined. The transmission and reception unit 120 may be used to instruct the transmission to the situation room, and when not in the error range, the second information of the vehicle may be instructed not to be transmitted to the situation room. In this case, the error range can be changed in the situation room, and the situation room can selectively distinguish the suspect vehicle because it can selectively acquire information of the vehicle group suspected of the suspect vehicles.

On the other hand, the first information may be any of the second information, that is, information searchable in the driving information unit 110. For example, when the first information is a unique identification number (or authentication number) of the stolen vehicle, the identification unit 130 is a unique identification number of the received stolen vehicle and a unique identification of the vehicle that has received the first information. By comparing the numbers, it is easy to determine whether the vehicle is a stolen vehicle.

In addition, the accident vehicle tracking device 100 is connected to the driving information unit 110 through a short-range wireless communication method such as Bluetooth or a wired communication method such as USB, the portable terminal 190 for reading the second information. ) May be further included. For example, the portable terminal 190 is designed to be easily carried by a police officer and secures a suspect vehicle, and then connects the driving information unit 110 with a short distance wireless or wired to download the driving information of the suspect vehicle. Can be. Therefore, the police officer can download the driving information of the accident vehicle in case of a traffic accident and submit it as evidence.

3 and 4 are schematic views for explaining an example of an accident vehicle tracking method according to the present invention shown in FIG.

3 and 4, all the vehicles are equipped with the above-described accident vehicle tracking device. The vehicle receives in real time the position information such as GPS coordinates from the GPS satellites, and stores the driving information for 48 hours or more. In case of hit by a traffic accident without a witness, the police situation room receives the location information of the traffic accident and the time information (D100) of the time of the accident from the reporter and sends the accident occurrence information to all vehicles in the country through the wireless network of the police own network. do. The accident occurrence information is analyzed and compared with the information stored in the accident vehicle tracking device of all vehicles.

The vehicle passing through the scene of the accident outside the accident time zone (D200) and the vehicle D400 leaving the scene at the time of the accident do not transmit their vehicle information to the police situation room because the accident occurrence information (location and time zone) do not match. . On the other hand, the vehicle (D300) escaped through the accident scene during the accident time zone coincides with the accident occurrence information, so that its vehicle location and vehicle information are automatically transmitted to the police situation room through the wireless communication network. The police situation room can then easily arrest the accident vehicle by tracking its current location.

According to the present invention as described above, there is an advantage that the suspect vehicle can be traced within a short time with only minimal information, for example, an accident occurrence location and an accident occurrence time, when a hit-off traffic accident occurs.

Therefore, when the accident vehicle tracking device is mandated to be mounted on the vehicle, it is possible to drastically reduce the hitting rate of hitting a traffic accident and to significantly improve the suspected arrest rate even if the hitting hit is a traffic accident.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and changed within the scope of the invention without departing from the spirit and scope of the invention described in the claims below I can understand that you can.
