## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of priority to Korean Patent Application No. 10-2014-0164257, filed on Nov. 24, 2014 with the Korean Intellectual Property Office, the disclosure of which is hereby incorporated by reference as if fully set forth herein.
TECHNICAL FIELD
The disclosure relates to a method and a system for car emergency, and more particularly to a system, emergency system and method, adapted in a vehicle, operable to detect an emergency situation when the vehicle is involved in an accident and to handle an emergency measure service.
BACKGROUND
Generally, an automobile accident causes damage or human life. Procedures and costs to determine the cause of the accident, and to deal with the aftermath, may become complicated.
For example, the procedures and the costs may be difficult to determine because no eye witness exists or all drivers and passengers have passed away after the accident.
To solve the above-described issues, on a telematics device in a vehicle, an emergency handling apparatus capable of detecting an automobile accident and automatically connecting to a call emergency center has been installed.
However, since it occasionally occurs that the telematics device is reset by detecting the automobile accident, the emergency handing apparatus cannot properly operate. Accordingly, it is a problem that the procedures to determine the cause of the accident, and to deal with the aftermath, may not address.
SUMMARY OF THE DISCLOSURE
Embodiments of the disclosure can be directed to a system, an emergency handling method and an emergency handling apparatus operable to turn on an emergency call unit included in a telematics device in order to automatically inform the status into a call emergency center, even when the telematics device is reset by an impact or a contact caused by automobile accident such as collision or crash.

FIG. 1 shows a vehicle emergency system.
As shown, the vehicle emergency system 100 may include an accident detection unit 110, a telematics unit 120, and a call center 130, in order to quickly handle an automobile accident.
First, the accident detection unit 100 may include at least one of a detection sensor 111 for sensing a collision or collision strength. In vehicle operation, the detection sensor 111 can sense a collision with another vehicle or object and generate an accident signal. Accordingly, the accident detection unit 110 can output the accident signal generated from the detection sensor 111.
By way of example but not limitation, the accident detection unit 110 can include an airbag sensor, an impact sensor, or an acceleration sensor, for detecting an airbag's impact or impact strength. Further, the accident detection unit 110 can include any sensor capable of detecting collision, collision strength, impact, or impact strength.
The telematics unit 120 receives the accident signal generated from the accident detection unit 110, and generates a flag signal in response to a received accident signal to store the flag signal.
Herein, the flag signal can be stored in a non-volatile memory 121. Accordingly, the flag signal stored in the non-volatile memory 121 is not deleted. The flag signal stored in the non-volatile memory 121 can include a flag state for emergency call.
Further, the telematics unit 120 can generate an accident message based on the generated flag signal. The accident message is a kind of information collected by the telematics unit 120 in response to the flag signal. The accident message can include a location of an accident, time and a type of fuel used in the vehicle, among other data points. The accident message can be stored in the non-volatile memory 121.
When the vehicle collides with another object or vehicle, the telematics unit 120 can be reset in response to the accident signal, or rebooted according to a reset procedure.
If a reset occurs, the telematics unit 120 can check the flag signal stored in the non-volatile memory 121 in order to automatically transfer the flag signal and/or the accident message stored in the non-volatile memory 121 into the call center server 130. Or, on or after reboot followed by reset, the telematics unit 120 can check the flag signal and/or the accident message stored in the non-volatile memory 121 to transmit them into the call center server 130.
The call center server 130, receiving the flag signal from the telematics unit 120, can recognize an emergency situation to report it to a manager, and try to connect an emergency call with the telematics unit 120. Or, the call center server 130 can run an emergency procedure when receiving the flag signal and/or the accident message.
The call center server 130 can precede an emergency call with the telematics unit 120 in response to the flag signal and/or the accident message, and handle or perform plural emergency actions after the emergency call in order to provide an accident sequence analysis regarding a vehicle after the automobile accident.
FIGS. 2 and 3 are flowcharts describing an emergency handling method in the vehicle emergency system.
As shown, the emergency handling method S100 for use in the vehicle emergency system 100 can include following steps S110, S120, S121, S130 in order to quickly handle an automobile accident.
In the step of S110, the detection sensor 111 included in the accident detection unit 110 can be used to sense an impact or a collision strength and generate the accident signal. When the accident signal is generated, the accident detection unit 110 can output the accident signal generated from the detection sensor 111.
In the step of S120, the accident signal generated in the step of S110 can be delivered into the telematics unit 120. In response to the accident signal, the flag signal can be generated by the telematics unit 120.
The generated flag signal can be stored in the non-volatile memory 121. The flag signal stored in the non-volatile memory 121 can include the flag state for emergency call.
In the step of S120, the accident message can be generated based on the flag signal. The accident message can include information collected by the telematics unit 120 in response to the flag signal. By way of example but not limitation, the accident message can include a location of an accident, time and a type of fuel used in the vehicle, among other data points. The accident message can be stored in the non-volatile memory 121.
In the step of S120, if the vehicle collides with another object or vehicle, a reset in response to the accident signal can occur in the telematics unit 120, or a rebooting according to a reset procedure can occur (S121).
If a reset occurs in the step of S120, the telematics unit 120 can check the flag signal stored in the non-volatile memory 121 in order to automatically transfer the flag signal and/or the accident message stored in the non-volatile memory 121 into the call center server 130. Further, on or after reboot followed by reset, the telematics unit 120 can check the flag signal and/or the accident message stored in the non-volatile memory 121 to transmit them into the call center server 130.
In the step of S130, when the call center server 130 receives the flag signal from the telematics unit 120, the call center server 130 can recognize an emergency situation to report it to a manager, and try to connect an emergency call with the telematics unit 120.
Further, in the step of S130, when the flag signal and/or the accident message is delivered from the telematics unit 120, the call center server 130 can run an emergency procedure after the emergency call between the telematics unit 120 and the call center server 130.
In the step of S130, the emergency call between the telematics unit 120 and the call center server 130 can be achieved in response to the flag signal and/or the accident message. Further, at the call center server 130, plural emergency actions can be performed after the emergency call in order to provide an accident sequence analysis regarding a vehicle after the automobile accident.
At that time, if the telematics unit 120 is connected with the call center server 130 via the emergency call (bi-directional call), the telematics unit 120 can delete the stored flag signal. This deletion is for overcoming a boundary of capacity in the nonvolatile memory 121.
