Terms to be described later are terms defined in consideration of functions in the present invention, and may be changed according to intentions or customs of users or operators. Therefore, the definition should be made based on the contents throughout the specification.

First, the concept of the present invention will be described with reference to FIG. 1 is a conceptual diagram illustrating the concept of the present invention.

The present invention is a service provided when a traffic accident occurs in a vehicle (A) equipped with a motion recognition mobile phone (100). In general, the vehicle A has a sudden speed change in at least one of the X, Y, and Z axis directions depending on whether the contact portion is in front, side, or rear. The present invention takes advantage of this sudden speed change.

That is, the present invention detects the acceleration change in the X, Y, Z-axis direction of the vehicle A in the motion recognition mobile phone 100 mounted on the vehicle A. In this state, when the vehicle A contacts the vehicle B of another person and a traffic accident occurs, the motion recognition mobile phone 100 determines whether the traffic accident is based on the acceleration change of the vehicle. When the motion recognition mobile phone 100 determines that the current situation is a traffic accident, it generates and stores information on the acceleration change of the vehicle in the X, Y, and Z directions based on time.

In addition, since the motion recognition mobile phone 100 is basically capable of communicating through a mobile communication network, if a mobile phone number for a specific person or a specific institution or place is registered, it is easy to inform the registered mobile phone number of the occurrence of a traffic accident.

In addition, when a short-range wireless communication device is mounted on the motion recognition mobile phone 100 and a traffic accident is warned through a short-range wireless communication device, another person's car (or mobile phone) passing through the surrounding is mounted on the motion recognition mobile phone 100. When a short range wireless communication device having a short range wireless communication device having a communication protocol of the same standard is provided, additional accidents can be prevented so that a traffic accident can be known.

Hereinafter, an example of a motion recognition mobile phone for the present invention will be described with reference to FIG. 2. 2 is a block diagram of a motion recognition mobile phone according to an embodiment of the present invention.

As shown in FIG. 2, the motion recognition mobile phone 100 of the present invention includes an acceleration sensor unit 110, a mobile communication unit 120, a control unit 130, a near field communication unit 140, a navigation unit 150, It includes an accident detection unit 160.

The acceleration sensor unit 110 detects a change in movement of the motion recognition mobile phone 100 in the X, Y, and Z directions. In order to detect the movement change in the three axis direction, the acceleration sensor unit 110 includes a Y-direction acceleration sensor 110a, an X-direction acceleration sensor 110b, and a Z-direction acceleration sensor 110c as shown in FIG. 3. do.

The acceleration sensors 110a, 110b, and 110c are sensors for detecting an acceleration of an object, that is, a change in speed per set time. The acceleration sensors 110a, 110b, and 110c do not react when the vehicle does not move or move at a constant speed, but detect a speed change at this time when the speed of the vehicle changes, and controls the acceleration signal corresponding to the speed change. 130).

The X-direction acceleration sensor 110a detects the speed change of the vehicle in the X direction, the Y-direction acceleration sensor 110b detects the speed change of the vehicle in the Y direction, and the Z-direction acceleration sensor 110c is the Z direction. Detect changes in the speed of the vehicle on. Here, the X direction is referred to as the forward and backward directions of the vehicle, the Y direction is referred to as the left and right side directions of the vehicle, and the Z direction is referred to as the height and the ground direction of the vehicle.

The mobile communication unit 120 is configured to interface with the mobile communication network and corresponds to a mobile communication module such as a CDMA module, a GSM module, or a WCDMA module, and receives data from the mobile communication network and transmits the data to the mobile communication network.

The short range wireless communication unit 140 is configured to interface with a mobile phone or a vehicle nearby, and has a built-in module for short range wireless communication such as Bluetooth communication or IrDA (infrared communication) or wireless LAN to warn of an accident. Send or broadcast a signal.

The navigation unit 150 has a built-in GPS (Global Positioning System), calculates the direction information of the vehicle based on the location information obtained from the GPS, and provides it on the screen when the user requests.

When the accident detection unit 160 receives the acceleration signal generated by the acceleration sensor unit 110, the directional information included in the received acceleration signal (that is, + X direction, -X direction, + Y direction, -Y direction, + Z direction, -Z direction), and the rate of change of acceleration input per unit time is calculated, and if the calculated rate of change of acceleration is equal to or greater than the set rate of change, it is determined as a traffic accident. The controller 130 calculates the rate of change of acceleration until there is no change in acceleration when it is determined that the traffic accident and then stores the time as a base in a storage unit (not shown). The navigation unit 150 stores the current location information and the driving direction information of the vehicle through the control unit 130, and the short range wireless communication unit 140 is driven through the control unit 130.

The controller 130 performs overall control of the components 110 to 160, and in particular, when receiving the acceleration signal from the acceleration sensor unit 110, provides the received acceleration signal to the accident detection unit 160, and detects the accident. The navigation unit 150 and the short range wireless communication unit 140 are controlled according to the request signal of the unit 160 to perform a setting operation corresponding to a traffic accident.

Hereinafter, a process of generating accident information in a motion recognition mobile phone according to an embodiment of the present invention will be described with reference to FIG. 4. 4 is a flowchart illustrating a method of generating accident information of a motion recognition mobile phone corresponding to a traffic accident according to an embodiment of the present invention.

First, the driver operates his motion recognition mobile phone 100 to select a traffic accident response service menu. At this time, the motion recognition mobile phone 100 is preferably fixed to the cradle.

Accordingly, the acceleration sensor unit 110 of the motion recognition mobile phone 100 detects a change in the moving speed of the vehicle and outputs acceleration information to the controller 130 when a change in speed occurs (S401). In general, acceleration information is generated and output only in the X-direction acceleration sensor 110b while driving a vehicle, but in a traffic accident, the acceleration information is not only in the X-direction acceleration sensor 100b but also in the Y or / and Z-direction acceleration sensors 110a and 110c. Is generated and output.

When the controller 130 receives the acceleration information from the acceleration sensor unit 110, the controller 130 provides the received acceleration information to the accident detection unit 160.

Upon receiving the acceleration information, the accident detector 160 calculates an acceleration change rate with respect to the set unit time (1 second, 2 seconds, 3 seconds, 10 seconds, etc.) of the received acceleration information (S402). The acceleration change rate calculated in this process S402 indicates a positive rate of change when the driving speed is larger than the initial driving speed, and a negative rate of change when the driving speed is smaller than the initial driving speed. Then, the greater the difference between the running speed and the initial driving speed, the greater the absolute rate of change.

When the acceleration change rate is calculated in this way, the accident detection unit 160 determines whether the acceleration change rate calculated by comparing the calculated acceleration change rate with the set change rate is more than the set change rate (S403).

Here, the determination process of S403 will be described in more detail.

Traffic accidents may occur when a vehicle in progress collides with a car in the front, a vehicle collides with a car in the side, and a car collides with a rear car. When hitting a car in front of the vehicle, the acceleration in the X direction usually changes suddenly in the negative direction, and the vehicle bounces in the Y or / and Z axes. When the vehicle suddenly changes in the positive direction and the vehicle turns, the acceleration in the X direction suddenly changes in the positive direction when it hits the rear car and moves in the Y-axis and / or Z-axis directions.

Therefore, the accident detection unit 160 stores the set change rate in the X, Y, and Z directions, and compares only the change rate regardless of the positive value or the negative value when comparing the change rate. At this time, the compared change rate is compared with all set change rates for the X, Y, and Z directions. If the calculated change rate in the X, Y, and Z directions is at least one set change rate (one of the X, Y, and Z directions), the traffic accident is referred to as a traffic accident. To judge.

The accident detecting unit 160 stores the rate of change in the X, Y, and Z directions calculated when the current situation is a traffic accident based on the determination of S403 (S404).

The accident detection unit 160 calculates and stores an acceleration change rate in the X, Y, and Z directions until acceleration information is not output from the acceleration sensor unit 110, that is, the vehicle stops. When the vehicle is stopped, current position information and vehicle traveling direction information are acquired from the navigation unit 150 and stored together with the acceleration change rate (S406).

Hereinafter, the operation of the present invention in a vehicle accident according to an embodiment of the present invention will be described with reference to FIG. 5. 5 is a flowchart illustrating an accident response service method of a motion recognition mobile phone corresponding to a traffic accident according to the present invention.

When a traffic accident occurs (S501), the speed of the vehicle is suddenly changed (S502), the sudden change of the speed is detected by the acceleration sensor unit 110 is provided to the accident detection unit 160 as an acceleration signal.

When the rate of change of the input acceleration information exceeds the setting, the accident detecting unit 160 determines that the traffic accident is calculated, and calculates the rate of change of acceleration in the X, Y, and Z directions accordingly (S503), and through the controller 130. The current position of the vehicle and the heading direction information of the vehicle are acquired from the navigation unit 150 (S504), and the current time is determined (S505).

Then, the accident detection unit 160 stores the acceleration change rate, time information, the current position of the vehicle, the direction of travel of the vehicle (S506), and the previously registered accident notification phone number using the mobile communication unit 120. Notify the occurrence of the traffic accident (S507). At this time, if the registered phone number is a mobile phone number of a specific person, an SMS message notifying a traffic accident is transmitted to the mobile phone number. If the registered phone number is a general phone number, the traffic accident is notified through the stored voice information.

At the same time, the accident detecting unit 160 notifies the occurrence of the accident to the short range wireless communication unit 140 through the control unit 130 so that a warning signal notifying the occurrence of the accident is transmitted from the short range wireless communication unit 140 (S508).

The technical spirit of the present invention has been described above with reference to the accompanying drawings, but this is by way of example only and not intended to limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.

According to the present invention, even if a vehicle is not provided with a separate device, the vehicle may be provided with a motion recognition mobile phone so that accident estimation information may be left in case of a traffic accident and an accident may be notified to the outside.
