Description
The present invention relates to a vehicle accident notification system and a control method thereof.
As the number of vehicle supply increases and the vehicle is perceived as a necessity of life, the driver has more time to drive the vehicle, the range of travel is widened, the risk of accidents increases, and the incidence of car accidents also increases.
Various systems have been introduced to prevent accidents as the number of accidents increases. For example, a lane departure warning system or a collision warning system has been commercialized as a vehicle.
Here, the Lane Departure Warning System (LDWS) is used to prevent the occurrence of an alarm and a Pre-Safe Seatbelt (PSB) when the lane departs without turning on the turn signal light to tighten the seatbelt The haptic function (Haptic Warning) is a device that causes the driver to be alerted. The Collision Warning with Brake Support (CWBS) monitors the distance to the vehicle ahead in real time using a radar. When a collision is detected, Is a device that warns of an accident risk.
In this way, the solution to prevent accidents is gradually developed and prototyped according to the improvement of technology. However, when there is no human area or no passenger, the accident can not be informed to the person There is a need for equipment that can urgently inform the emergency situation after an accident.
To alleviate this problem, an accident notification device has been developed that provides an accident notification service that allows a vehicle to automatically transmit a predetermined text message or voice message to a designated contact when a crash occurs in the vehicle.
However, since such an accident notification device is mounted in a vehicle, if the accident notification device is damaged due to an accident, it is not operated normally and thus an accident notification service can not be provided.
Accordingly, a technical problem to be solved by the present invention is to automatically report the occurrence of a vehicle accident together with an accident location when an accident occurs in a vehicle, thereby promptly treating the accident and reducing the damage of the person.
Another technical problem to be solved by the present invention is to accurately ascertain whether an accident has occurred in a vehicle and improve the reliability of the operation.
According to an aspect of the present invention, a vehicle accident notification system includes a vehicle terminal attached to a vehicle, the vehicle terminal including: an acceleration sensor for detecting an acceleration of the vehicle and outputting a signal of the corresponding state; And an angular velocity sensor connected to the acceleration sensor and the angular velocity sensor for determining an acceleration and an angular velocity using a detection signal output from the acceleration sensor and the angular velocity sensor, Is compared with the magnitude of the second set acceleration and the magnitude of the second set angular velocity, respectively, and if the magnitude of the determined acceleration and acceleration are equal to or greater than the magnitudes of the second set acceleration and the second set angular velocity, respectively, And transmits a preliminary accident occurrence notification signal to the user terminal .
The vehicle accident notification system according to the above feature may further include a user terminal mounted on the vehicle, wherein the user terminal includes an acceleration sensor for detecting an acceleration of the user terminal and outputting a signal of a corresponding state, An angular velocity sensor for sensing the angular velocity of the terminal and outputting a signal of the corresponding state, a gravity sensor for sensing the altitude of the vehicle, a magnetic sensor for sensing the orientation of the vehicle, And an acceleration sensor connected to the acceleration sensor, the angular velocity sensor, the gravity sensor, the magnetic sensor, and the position data acquisition unit, wherein the magnitude of the acceleration of the vehicle sensed by the acceleration sensor and the magnitude of the acceleration sensed by the angular velocity sensor Current impact information, which is the magnitude of the angular velocity of the vehicle, Determines the present altitude of the vehicle sensed by the magnetic sensor, the current azimuth of the vehicle sensed by the magnetic sensor, and the current vehicle position information sensed by the position data acquisition unit, and transmits a preliminary accident occurrence notification signal Judges whether or not the vehicle terminal identification number of the vehicle terminal and the vehicle terminal identification number transmitted from the vehicle terminal together with the preliminary accident occurrence notification signal are identical to each other when the preliminary accident occurrence notification signal is transmitted from the vehicle terminal, It is determined whether the current acceleration magnitude and the current angular velocity magnitude are equal to the transmitted acceleration magnitude and the angular velocity magnitude when the vehicle terminal identification number of the terminal and the vehicle terminal identification number transmitted together with the preliminary accident occurrence notification signal are equal to each other, The magnitude of the transmitted acceleration magnitude, and the current angular velocity magnitude And an operation control unit for determining the state of the corresponding vehicle equipped with the vehicle terminal as an accident state when the transmitted angular velocity sizes are equal to each other.
According to another aspect of the present invention, there is provided a method for controlling a vehicle accident notification system, the method comprising: determining whether a state of a corresponding vehicle is determined as an accident occurrence state, and when the state of the vehicle is determined as an accident occurrence state, Transmitting the accident occurrence notification signal and the vehicle terminal identification number to the control server, and when the accident occurrence notification signal is transmitted from the user terminal, the control server transmits the vehicle information of the accident occurrence vehicle to the database The database transmits the vehicle information of the corresponding vehicle to the control server using the transmitted terminal identification number, and the control server stores the vehicle information of the corresponding vehicle transmitted from the database in the storage unit The control server sends the incident reception message to the user terminal, Transmitting, and the user terminal includes the step of outputting the incident received message transmitted from the control server.
According to this aspect, the position of the accident vehicle and the degree of the accident are automatically estimated by the driver even after the occurrence of the accident of the vehicle, even if the driver is unconscious. As a result, not only the economic loss but also the loss of human life due to rapid accident handling is reduced.
Further, an accident determination operation of the vehicle is performed in duplicate in the vehicle terminal and the user terminal, and it is judged accurately whether an accident has occurred or not. Therefore, it is judged whether or not an accident has occurred correctly, so that it is possible to erroneously determine whether or not an accident has occurred, thereby reducing a malfunction of the vehicle accident notification system and improving the reliability of the operation.
