If any one of the plurality of tires 11, 12, 13, and 14 is punctured or has a problem, the speed of the tire with the problem may be different from that of the other tires, and then the speed of the vehicle is rapidly reduced. If it stops, it can be judged that an accident has occurred. As such, sensing the speed of each of the plurality of tires 11, 12, 13, and 14 may be more important than detecting the simple speed of the vehicle itself. In addition, it is possible to accurately determine whether or not an accident occurs even if the vehicle does not have a separate collision sensor to detect an accident of the vehicle.

Specifically, the plurality of sensors 111, 112, 113, and 114 may be disposed on at least two of the plurality of tires 11, 12, 13, and 14, and all of the tires 11, 12, 13, and 14 Of course, the sensors 111, 112, 113, and 114 may be disposed.

Vehicle speed information P1 may be generated. Here, the vehicle speed information may include each tire speed information detected by the plurality of sensors 111 , 112 , 113 , and 114 and average value information of each tire speed information. The control unit 120 includes a communication unit that communicates with the plurality of sensors 111, 112, 113, and 114, and uses the respective tire speeds transmitted from the plurality of sensors 111, 112, 113, and 114 to speed the vehicle. Information P1 may be generated, and the generated vehicle speed information P1 may be transmitted to the server 30 .

The controller 120 may also perform a function of transmitting tire speed information detected by the plurality of sensors 111 , 112 , 113 , and 114 to the display of the vehicle or the user terminal 20 . As another embodiment, the control unit 120 uses the tire identification code information stored in the RFID sensor to determine the tire manufacturer, tire size, tire pattern, and tire load index. ), tire speed symbol, tire max pressure, tire tread wear, tire spec number, and tire temperature. information can be processed. In addition, the control unit 120 uses the tire specification information to provide information on one or more of tire current condition information, for example, tire wear condition, road surface condition in contact with the tire, abnormal air pressure in the tire, abnormal heat in the tire, and abnormal part of the tire. It is possible to process state information including.

As another embodiment, the controller 120 may receive vehicle location information from the vehicle's GPS module 200 . In addition, the control unit 120 may also receive vehicle speed information from the vehicle GPS module 200 and use the speed information P1 provided from the speed detection module 100 as information for determining an accident. . The controller 120 may generate vehicle location information, vehicle speed information, and vehicle identification information as one set of data and transmit it to the server 30 .

Meanwhile, the server 30 may receive vehicle speed information detected by the speed detection module 100 and determine whether the vehicle has been in an accident using the vehicle location information and speed information. When it is determined that it is an accident through the above information, the server 30 generates accident information (P3) including the location of the vehicle and the type of accident, and sends a message including the accident information (P3) to a pre-stored emergency contact. can transmit

Here, in providing the vehicle speed information to the server 30, the speed detection module 100 may provide the vehicle speed information P1 to the server 30 in correspondence with the vehicle identification information. The server 30 collects speed information and location information about a plurality of vehicles, and when accident information is generated, it is possible to prevent secondary accidents in advance by transmitting the accident information to vehicles located within a certain distance from the accident location. there is.

Alternatively, the emergency contact network 40 may be at least one of a police station, a 119 disaster center, and a contact manually stored by a user. As another embodiment, the emergency contact network 40 may be a user terminal 20 of another vehicle located within a predetermined distance from the accident location of the accident vehicle as well as contacts pre-stored in the server 30 . In other words, in the case of deserted mountain roads or driving at dawn, even if an emergency call is made to the police station or 119 disaster center, it may not come quickly. In this case, a message including accident information may be transmitted to the user terminal 20 of a vehicle moving nearby, and emergency relief by the private sector may be induced.

Hereinafter, an emergency rescue method for an accident vehicle according to an embodiment of the present invention will be described with reference to FIGS. 3 to 6 .

3 is a flowchart sequentially illustrating an emergency relief method for an accident vehicle according to an embodiment of the present invention, and FIGS. 4 to 6 are diagrams for explaining methods for determining an accident in a server.

Referring to FIG. 3 , the emergency relief method for an accident vehicle according to an embodiment of the present invention includes receiving vehicle speed information P1 from the speed detection module 100 disposed in the vehicle (S100), and the location of the vehicle. Determining whether a vehicle has been in an accident using information and speed information, and generating accident information (P3) including the location and accident type of the vehicle if it is determined to be an accident (S200), and the accident information as a pre-stored emergency contact It may include transmitting a message including (P3) (S300).

Specifically, the server 30 may receive vehicle speed information P1 from the speed detection module 100 disposed in the vehicle (S100). As described above, the vehicle speed information P1 includes each tire speed information detected from the plurality of sensors 111, 112, 113, and 114 attached to each tire and average value information of each tire speed information. can include The server 30 may determine whether the vehicle has been in an accident using the speed information P1 and the vehicle location information P2.

Referring to FIG. 4 , the server 30 may receive vehicle speed information P1 in real time or according to a preset period (S100). After that, the server 30, after the speed of the vehicle is decelerated beyond the preset deceleration range for a first preset time (S211), when the vehicle's speed becomes 0 km/h, that is, when the vehicle stops (S212 ), it can be determined that it is a first-type accident (S213). Here, the first type of accident may be a general crash accident. When the server 30 determines that it is an accident of the first type, the first accident information including the location information P2 of the vehicle, the time information, and the first accident type may be generated and transmitted to an emergency contact.

If, after the speed of the vehicle is decelerated beyond a preset deceleration range (S211) and the vehicle does not stop, the server 30 may manage the corresponding vehicle as an observation for a certain period of time (S214). The server 30 may determine that the speed is decelerated by the driver's action when a change in the speed of the vehicle occurs for a predetermined period of time. Alternatively, if the vehicle speed continues at a low speed for a certain period of time or cannot move away from the location where the accident information was generated, the server 30 may also determine that an accident has occurred and generate first accident information and forward it to an emergency contact. .

Referring to FIG. 5 , the server 30 accelerates the speed of the vehicle beyond the preset acceleration range for a preset 2-1 time period (S221), and does not decelerate for a preset 2-2 time period. In this case (S222), it can be determined as a second type of accident (S223). Here, the second type of accident may be a sudden acceleration accident. When the server 30 determines that it is a second type of accident, the second accident information including the location information P2 of the vehicle, the time information, and the second accident type may be generated and transmitted to an emergency contact.

In the case of a sudden acceleration accident, most crashes occur because the driver cannot control the vehicle, but in some cases, the steering wheel is controlled in a sudden acceleration state. In this case, since the driver cannot report an emergency, when such a sudden acceleration accident occurs, the location of the vehicle can be continuously tracked and transmitted to an emergency rescue vehicle such as a police car.

If, after the speed of the vehicle is accelerated beyond the set acceleration range for the preset 2-1 time (S222), if the vehicle stops (S224), it is determined that this is a first-type accident, which is a collision accident (S225) Accident information can be transmitted to an emergency contact. Alternatively, if the vehicle does not stop after the speed of the vehicle is accelerated beyond the acceleration range set for the preset 2-1 time period (S224), the server 30 may manage the corresponding vehicle as attention observation for a predetermined period of time. Yes (S226).

Referring to FIG. 6, the server 30 intermittently adjusts 1 to 10 rpm after a difference in the speed of any one of the tires exceeds the preset reference range during the preset 3-1 time period (S231). When it is detected at a speed of (S232), it can be determined that it is a third type of accident (S233). Here, the third type of accident may mean a rollover accident. When the server 30 determines that it is a third type of accident, the third accident information including the location information P2 of the vehicle, the time information, and the third accident type may be generated and transmitted to an emergency contact.

That is, when the vehicle falls off a cliff or is overturned, the tires are not stopped but may be detected at a weak speed.

If, after a difference in the speed of any one of the tires exceeds the preset reference range during the preset 3-1 time (S231), if the vehicle does not stop (S235), it is not considered an accident and the server ( 30) may manage the vehicle as an observation for a certain period of time (S236).

Alternatively, if the vehicle stops (S235) after a difference in the speed of one of the tires exceeds the preset reference range during the preset 3-1 time (S231), an attempt is made to contact the user terminal 20. It can (S235). At this time, if a reply comes to the user terminal 20, the server 30 may manage the corresponding vehicle as an attention observation for a certain period of time without considering it as an accident (S236). However, if no reply is received from the user terminal 20 for a certain period of time, the server 30 may determine that it is a first accident type and transmit first accident information to an emergency contact.

As described above, the emergency rescue system and method for an accident vehicle according to an embodiment of the present invention determines whether an accident occurs using tire speed information, and transmits accident information to an emergency contact when it is determined to be an accident. It can provide quick relief to drivers who are in trouble due to rare or early morning driving.

As such, the present invention has been described with reference to one embodiment shown in the drawings, but this is merely exemplary, and those skilled in the art will understand that various modifications and variations of the embodiment are possible therefrom. Therefore, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims.
