Hereinafter, an operation and a transmission / reception method of the vehicle information transmission and reception device configured as described above will be described with reference to FIG. 2.

In step S1, the control unit 12 detects and codes each signal generated from the brake operation state detection means for detecting the operation state of the speed sensor, the acceleration sensor, the hand brake or the foot brake, the fuel state detection means, and the airbag unit. ) Is stored periodically or in a situation of memory (18).

In step S2, the position signal is detected from the GPS receiver of the position detecting unit 11 to determine the current position of the vehicle, and the vehicle is calculated by calculating the position moved according to the vehicle speed, brake, and acceleration information detected in the step S1. The position and time data are corrected and the corrected information is input to the control unit 12.

In other words, by analyzing the position information and the time information output from the GPS receiver, the control unit 12 sets the system time setting and position information in the memory 18, and the position information that is continuously corrected is periodically stored in the memory 18. It is stored and used as vehicle location information when transmitting information by communication. At this time, the main server installed in the control center can grasp the information such as the position, speed, brake operation status, airbag operation status of the vehicle and can use it as additional information.

Subsequently, in the first judging step S3, the base value set in the memory 18 and the signal input in the step are compared to determine whether an accident has occurred, and if no accident has occurred, the process proceeds to the next judging step S4. If an accident occurs, the process proceeds to the next step (S5).

In step S5, when it is determined that the vehicle signal detected in the first judging step S3 is in an abnormal state, the control unit 12 includes vehicle information together with the current position and time data of the vehicle already input through the GPS receiver. The transmission to the remote control center via the transceiver 13. In addition, the control unit 12 may display an abnormal state through a display unit (not shown) in text or graphics.
