Next, the operation of this embodiment will be described. In FIG. 1, at normal times other than the emergency call transmission process, the position information acquisition processing unit 14 calculates the own vehicle position calculated based on the data received by the GPS receiver 17 from the GPS antenna 4, the traveling direction, the direction, and the like of the vehicle. From the gyro sensor 13 for generating the vehicle information, and the vehicle speed signal generation circuit 8
A correction process is performed based on the distance information calculated based on the vehicle speed signal from the vehicle, and an accurate vehicle position is always grasped.

In an emergency such as a traffic accident or sudden illness, the user presses the emergency call button 3. The emergency call transmission button 3 outputs an operation signal indicating that the button has been pressed by the user to the control unit 12. The control unit 12 outputs a signal requesting the current position information to the position information acquisition processing unit 14.
The position information acquisition processing unit 14 inputs data from the gyro sensor 13 for generating information such as the traveling direction and direction of the vehicle and data from the vehicle speed signal generation circuit 8 in response to the position information request signal from the control unit 12. At the same time, the GPS receiver 17 inputs data such as position information generated from data received from the GPS antenna 4 and outputs the data to the control unit 12.

The control unit 12 obtains the telephone number of the emergency call center from the storage unit 15 and makes a call request such as a telephone call to the emergency call contact means 11 using the telephone number. Emergency call notification means 11 uses telephone antenna 2 to start a telephone call process to the other party corresponding to the telephone number via the base station of the communication carrier. When receiving an outgoing call response from the other party or a signal such as a busy signal that shifts to a busy state, the emergency call notification unit 11 recognizes that the state has shifted to the talking state, and shifts to voice call control or data communication control. At the same time, it outputs a signal to the control unit 12 to notify that the call has been transferred. Control unit 12 determines that it has successfully call, create a traveling direction of the vehicle obtained from the position information acquisition processing section 14, information such as orientation, and location information <br/> of which transmission data, operators Through the base station or the like to make a call to the emergency call center corresponding to the telephone number corresponding to the telephone number.

When the control unit 12 completes the data communication processing for the emergency call center, the hands-free system 1
The operation shifts to a voice call through 6. When shifting to a voice call, the voice signal received from the emergency call notification means 11 is subjected to processing such as echo cancellation by the hands-free system 16 and output as voice from the speaker 6. The audio signal input from the microphone 5 is subjected to processing such as echo cancellation by the hands-free system 16, and is output to the emergency call communication means as a transmission audio signal. At the time of a voice call, a voice call is made between the user and the operator of the emergency call center, and a report such as an accident situation is executed by voice.

In the first embodiment , the emergency call notification means 1
The time data is obtained from "telephone JJY" by calling from "1". That is, the control unit 12 controls the storage unit 15
The telephone number of "telephone JJY" is obtained from the telephone number, and the telephone call is requested to the emergency call communication means 11 using this telephone number. Emergency call notification means 11 uses telephone antenna 2 to start a telephone call process to the other party corresponding to the telephone number via the base station of the communication carrier. Further, when receiving an outgoing call response from a call partner or a signal that shifts to a call state such as a busy signal, the emergency call notification unit 11 recognizes that the state has shifted to a call state and performs voice call control or data communication control. With the transition,
A signal notifying that the call has been transferred is output to the control unit 12. The control unit 12 determines that the call is successful, and performs a process of inputting time data output from the “telephone JJY”. When transmitting the emergency report by the user pressing the emergency report button 3 or the like, when generating the transmission data to be transmitted to the emergency report center, the control unit 12 includes, as a part of the transmission data, the time obtained from the "telephone JJY" The transmission data is generated by adding the data and transmitted to the emergency call center.

[0021] Incidentally, in the first embodiment, the control unit 12, based on the time data obtained from the "Te Rehon JJY" emergency call system terminal clock device 1 has therein, for example, real-time clock in the controller 12 Can be calibrated. The controller 12 can perform the calibration at a timing when accessory power is turned on, such as when the engine is started, or periodically based on time data. Thereby, the control unit 12 can always maintain accurate time data.

[0022] Second Embodiment FIG. 2 shows the configuration of the emergency call system terminal device in the second embodiment of the present invention, in the first embodiment, the

(Embodiment 3 ) FIG. 3 shows calibration of an emergency call system terminal device according to Embodiment 3 of the present invention. In the third embodiment, FIG.
Is different from the first embodiment described in
Receiving time data transmitted by short-wave transmission from "JJY"
"JJY" received by the receiving antenna 7 and the receiving antenna 7
Signal that obtains time data by demodulating short-wave signals from
The communication device 18 and the control unit 12 compare the time data obtained from “JJY” or “telephone JJY” with the time data of the internal clock to determine whether or not the error is within a certain range. as well as, if the error exceeds a predetermined range, and a trouble display unit 20 for informing the user that either the internal clock or acquired time data is abnormal, further internal clock or An external device connection interface 21 for outputting to the external connection device 9 connected to the emergency notification system terminal device 1 that the acquired time data is abnormal is provided.

If the time of the internal clock and the time data obtained from the radio signal receiver 18 have an error of a fixed time or more, the control unit 12 determines which of the internal clock and the obtained time data is abnormal. Is determined, the result of the determination is stored in the storage unit 15, and a signal notifying the abnormality is output to the abnormality display means 20. The abnormality display means 20 informs the user of the abnormality of the time data by lighting or blinking by an indicator such as an LED, a character display using an LCD or the like, a warning sound by a beep sound, a voice message by a synthetic voice, or the like.

Further, the external device connection interface 2
When the external connection device 9 is connected to the external device 1 and a data read signal is transmitted from the external connection device 9, the signal is transmitted to the control unit 12 via the external device connection interface 21. The stored history data including the time data abnormality is read out and output to the externally connected device 9 via the external device connection interface 21. The externally connected device 9 records the read history data on a recording medium such as a magnetic disk, and prints the data on paper using a printer. The recording unit 15 stores, in addition to the time data abnormality, the position information obtained from the GPS receiver 17, the vehicle speed signal input from the vehicle speed signal generation circuit 8, and the data such as the traveling direction and direction of the vehicle input from the gyro sensor 13. And the time information, the data is taken out through the externally connected device 9 so that the vehicle equipped with the emergency call system terminal device 1
