Cooperative event data record system and method

A cooperative event data record system comprising an in-car system working cooperatively with a communication system having a communication module element, said in-car system comprising:

• a communication module, a cooperative event record processing unit, and an impact determination module, and said cooperative event record processing unit being connected respectively to said communication module, said impact determination module, and an event data record unit;
• wherein said impact determination module transmits an alarm to said cooperative event record processing unit, said communication module transmits a request from said cooperative event record processing unit to said communication module element, and receives a response from said communication module element, and said cooperative event record processing unit, according to said response transmitted from said communication module, stores at least a video data to an event data record unit or retrieves video data from said event data record unit;
• and
• wherein said communication system is configured as a backend system, and said backend system further comprises an video record database, said video record database connects to said communication module element.

A cooperative event data record system comprising an in-car system working cooperatively with a communication system having a communication module element, said in-car system comprising:

• a communication module, a cooperative event record processing unit, and an impact determination module, and said cooperative event record processing unit being connected respectively to said communication module, said impact determination module, and an event data record unit;
• wherein said impact determination module transmits an alarm to said cooperative event record processing unit, said communication module transmits a request from said cooperative event record processing unit to said communication module element, and receives a response from said communication module element, and said cooperative event record processing unit, according to said response transmitted from said communication module, stores at least a video data to an event data record unit or retrieves video data from said event data record unit;
• and
• wherein said communication system is configured as a road side equipment, said road side equipment further comprises a camera device, and said camera device is connected to said communication module element.

A cooperative event data record method, applicable to an in-car system having a communication module, a cooperative event record processing unit, and an impact determination module, said method comprising:

• transmitting by said impact determination module a signal to said cooperative event record processing unit;
• transmitting by said communication module a request from said cooperative event record processing unit to a communication module element;
• transmitting by said communication module element a response back to said communication module;
• and
• according to at least a response transmitted from said communication module, said cooperative event record processing unit retrieving video data from or storing video data to an event data record unit;
• wherein when an accident occurs, said method further comprises:
• selecting, by said accident car, at least a critical neighboring car;
• and
• requesting said at least a critical neighboring car to transmit video data.
