         [0039]      FIG. 1  is a block diagram of a device for providing vehicle accident information according to an exemplary embodiment of the present inventive concept. 
         [0040]    A device for providing vehicle accident information  10  of  FIG. 1  includes a memory  100  storing a plurality of instructions, and a processor  200  connected to the memory  100  and reacting to the plurality of instructions. 
         [0041]    Here, a vehicle terminal device  300  and a mobile device  400  are connected to the processor  200 , and they are connected to a remote server  20  through the wireless communication network. 
         [0042]    For example, a device for providing vehicle accident information  10  may be device implemented in a computer system. 
         [0043]      FIG. 2  is a block diagram of a memory of  FIG. 1 . 
         [0044]    The memory  100  of  FIG. 2  includes an accident detecting instruction  110 , an accident information collection instruction  120 , an accident information transmission instruction  130 , a path change instruction  140 , a context information collection instruction  150 , and a context information transmission instruction  160 . 
         [0045]    The accident detecting instruction  110  detects a vehicle accident using the vehicle terminal device  300 . 
         [0046]    The vehicle terminal device  300  detects the vehicle accident using a plurality of sensors or cameras. 
         [0047]    In addition, when an occupant controls a specific button (SOS button) of the vehicle, the vehicle accident is detected. 
         [0048]    For example, when an impact of a vehicle is detected through an impact detecting sensor installed in the vehicle or inflating of an air bag, it can be determined that a crash or bump accident has occurred. 
         [0049]    The vehicle terminal device  300  may be a telematics device. 
         [0050]    The accident detecting instruction  110  detects the vehicle accident using the mobile device  400 . 
         [0051]    The mobile device  400  includes a plurality of mobile devices  410 ,  420 , and  430 , and may be a portable terminal owned by a driver or a passenger or a wearable terminal attached to a body portion of the driver or the passenger. 
         [0052]    In this case, the portable terminal provides one of voice calls, image calls, or wireless communication, and the portable terminal may include a camera. 
         [0053]    In addition, the wearable terminal may include one of sensors sensing biological information of the driver or the passenger. 
         [0054]    The accident detecting instruction  110  detects the vehicle accident using a first mobile device  410  of the driver. 
         [0055]    The first mobile device  410  of the driver detects the vehicle accident using a plurality of sensors, cameras, or preinstalled accident detecting programs (applications). 
         [0056]    For example, when an impact is detected through an acceleration sensor, or when a vehicle speed change similar to a preset pattern is detected with the driver in the vehicle, it can be determined that the crash or bump accident has occurred. 
         [0057]    In this case, the presence of the driver may be detected through automatic pairing of a vehicle head unit and the first mobile device  410  or a driving mode setting by using the first mobile device  410 . 
         [0058]    When the vehicle accident is detected through the accident detecting instruction  110 , the accident information collection instruction  120  collects information related to the vehicle accident (hereinafter referred to as accident information). 
         [0059]    In this case, the accident information collection instruction  120  collects the accident information by using the vehicle terminal device  300  or the mobile device  400  that detects the vehicle accident. 
         [0060]    For example, the accident information collection instruction  120  may collect current location information using a GPS (global positioning system) or may collect an image of an image recording device for a vehicle (a vehicle black box). 
         [0061]    The accident information transmission instruction  130  transmits the accident information to the server  20 . 
         [0062]    In this case, the accident information transmission instruction  130  transmits the accident information to the server  20  using the vehicle terminal device  300  or the mobile device  400  that detects the vehicle accident. 
         [0063]    The path change instruction  140  changes an information transmission path according to a path change request of the server  20 . 
         [0064]    Specifically, after the vehicle terminal device  300  or the mobile device  400  detects the vehicle accident, a different device may collect and transmit spot information (hereinafter referred to as context information) after an accident. 
         [0065]    The path change instruction  140  may set the context information collecting and transmitting device according to an initial condition. 
         [0066]    For example, when a power-off or a failure according to the vehicle accident of the vehicle terminal device  300  that transmits the accident information is detected, it may set the mobile device  400  as the context information collecting and transmitting device. 
         [0067]    In addition, when a power-off or a failure according to the vehicle accident of the first mobile device  410  that transmits the accident information is detected, it may set the other mobile devices  420  and  430  as the context information collecting and transmitting device. 
         [0068]    The path change instruction  140  may set the context information collecting and transmitting device through the accident information transmission instruction  120 , as soon as the accident information is transmitted to the server  20 . 
         [0069]    The path change instruction  140  may set at least one of mobile devices  410 ,  420 , and  430  satisfying the initial condition among a plurality of mobile devices as the context information collecting and transmitting device. 
         [0070]    In this case, the condition can be set as follows, and at least one or more conditions can be set. 
         [0071]    Condition 1) A mobile device having the strongest wireless signal strength 
         [0072]    Condition 2) A mobile device having the largest number of connections with the server 
         [0073]    Condition 3) A mobile device that was most recently connected with the server through the wireless communication network 
         [0074]    Condition 4) A mobile device having the highest battery charge amount 
         [0075]    Condition 5) A mobile device of a vehicle driver that is preset 
         [0076]    For example, when the Condition 2 is a setting condition of the context information collecting and transmitting device, a mobile device having the largest number of connections with the server  20  among the plurality of mobile devices  410 ,  420 , and  430  can be set as the context information collecting and transmitting device. 
         [0077]    In this case, when there is no mobile device that has connected with the server  20  at least once, all mobile devices can be set as the context information collecting and transmitting device. 
         [0078]    The context information collection instruction  150  collects the context information in real time by using the mobile devices  410 ,  420 , and  430  that are set as the context information collecting and transmitting device through a path change instruction  140 . 
         [0079]    In this case, the context information includes all information which may be collected by the mobile devices  410 ,  420 , and  430 . 
         [0080]    For example, the context information can include at least one of a vehicle position, an accident image, an accident sound, or biological information of an occupant (temperature, pulse, respiration, blood sugar, brain wave, fatigue index, etc.). 
         [0081]    The context information transmission instruction  160  transmits the context information collected through the context information collection instruction  150  to the server  20 . 
         [0082]    In addition, it can transmit to an accident-related agency. 
         [0083]    In this case, it transmits the context information through the mobile devices  410 ,  420 , and  430  that collect the context information. 
         [0084]    The server  20  requests a path change after receiving the accident information. 
         [0085]    The server  20  receives the accident information received through the accident information transmission instruction  130 , and notifies an accident occurrence to or requests a rescue by the accident-related agency. 
         [0086]    In this case, the server  20  can notify the accident occurrence or request a rescue in accordance with the analysis result of the accident information. 
         [0087]    For example, after receiving the accident information and reporting the nearest police station of the current position of the vehicle, and if a fire is detected by analyzing the image of an image recording device for a vehicle (a vehicle black box) in the accident information, it can request fire suppression and rescue by a fire station. 
         [0088]    The server  20  receives context information transmitted by the context information transmission instruction  160 , and analyzes the context (accident scale, fire suppression condition of accident, occurrence of casualties, etc.), and additionally requests rescuers and an ambulance from the related agency according to an analysis result. 
         [0089]      FIG. 3  is a flowchart of a method for providing vehicle accident information by using a vehicle terminal device and a mobile device according to an exemplary embodiment of the present inventive concept. 
         [0090]      FIG. 3  shows an example of a method for providing vehicle accident information to change an information transmission path from the vehicle terminal device to the mobile device. 
         [0091]    The vehicle terminal device  300  detects the vehicle accident through the accident detecting instruction  110  (S 11 ). 
         [0092]    If the vehicle accident is detected in the step S 11 , the vehicle terminal device  300  collects the accident information through the accident information collection instruction  120  (S 12 ), and transmits it to the server  20  though the accident information transmission instruction  130  (S 13 ). 
         [0093]    The server  20  reports the accident occurrence to the related agency based on the accident information transmitted in the step S 13  (S 14 ). 
         [0094]    The server  20  requests the path change after the step S 14  or simultaneously with the step S 14  (S 15 ). 
         [0095]    The path change instruction  140  sets the context information collecting and transmitting device (the first mobile device  410 ) according to the request of the server  20  of the step S 15 , and the first mobile device  410  collects the context information through the context information collection instruction  150  (S 16 ). 
         [0096]    In this case, the path change instruction  140  can set at least one mobile device satisfying the initial condition as the context information collecting and transmitting device. 
         [0097]    The first mobile device  410  transmits the context information to the server  20  through the context information transmission instruction  160  (S 17 ). 
         [0098]    The server  20  performs follow-up measures by analyzing the context information transmitted in the step S 17  (S 18 ). 
         [0099]    In this case, it analyzes the accident scale, the fire suppression condition of the accident, and occurrence of casualties based on context information, and additionally requests rescuers and an ambulance from the related agency according to the analysis result. 
         [0100]      FIG. 4  is a flowchart of a method for providing vehicle accident information by using a mobile device according to an exemplary embodiment of the present inventive concept. 
         [0101]      FIG. 4  shows an example of a method for providing vehicle accident information to change an information transmission path from a first mobile device to a second mobile device. 
         [0102]    The first mobile device  410  detects the vehicle accident through the accident detecting instruction  110  (S 21 ). 
         [0103]    In this case, the first mobile device  410  may be a mobile device of a driver. 
         [0104]    If the vehicle accident is detected in the step S 21 , the first mobile device  410  collects the accident information through the accident information collection instruction  120 , and transmits it to the server  20  though the accident information transmission instruction  130  (S 23 ). 
         [0105]    The server  20  reports the accident occurrence to the related agency based on the accident information transmitted in the step S 23  (S 24 ). 
         [0106]    The server  20  requests the path change after the step S 24  or simultaneously with the step S 24  (S 25 ). 
         [0107]    The path change instruction  140  sets the context information collecting and transmitting device (the second mobile device  420 ) according to a request of the server  20  of the step S 25 , and the second mobile device  420  collects the context information through the context information collection instruction  150  (S 26 ). 
         [0108]    In this case, the second mobile device  420  may be a mobile device of the passenger. 
         [0109]    The path change instruction  140  can set at least one mobile device satisfying the initial condition as the context information collecting and transmitting device. 
         [0110]    When the first mobile device  410  conducting the step S 21  and the step S 22  satisfies the initial condition, the path change instruction  140  sets the first mobile device  410  as the context information collecting and transmitting device, and the first mobile device  410  can collect the context information through the context information collection instruction  150  (S 26 ). 
         [0111]    The second mobile device  420  transmits the context information to the server  20  through the context information transmission instruction  160  (S 27 ). 
         [0112]    The server  20  performs follow-up measures by analyzing context information transmitted in the step S 27  (S 28 ). 
         [0113]    In this case, it analyzes the accident scale, the fire suppression condition of the accident, and occurrence of casualties based on context information, and additionally requests rescuers and an ambulance from the related agency according to an analysis result. 
         [0114]    According to the exemplary embodiment of the present inventive concept, when the vehicle terminal device is unable to be used due to the vehicle accident, it may collect context information in real time by using the mobile device of an occupant, and rapidly rescue victims of the accident based on the context information. 
         [0115]    According to the exemplary embodiment of the present inventive concept, by collecting the context information of each occupant by using the mobile device of the occupant and performing follow-up measures according the context information, it is possible to reduce the casualties. 
         [0116]    While this inventive concept has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the inventive concept is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
