Further, the control circuit 114 instructs the sound reproduction circuit 111 to output a sound notifying that the emergency notification communication process is being performed. The audio reproduction circuit 111 performs an audio reproduction process using the internally recorded audio phrase data and the like, and outputs the audio data to the speaker amplifier 112. The speaker amplifier 112 uses the speaker 11 to execute a sound reproduction process of a sound for sound reproduction. Also, in the case of takeover of a vehicle, extortion, etc., it is necessary to carry out an emergency call notification process without the harmful person noticing.

Next, a specific example of the emergency call transmission process using the transmission button B8 will be described below. The transmission button B8 outputs a signal indicating that the button has been pressed. Emergency call signal detection circuit 10
Reference numeral 6 receives a push signal of the send button B8 and outputs the signal to the control circuit 114 as a signal indicating that the push button B8 is pressed. The control circuit 114 controls the audio
At the same time as instructing to connect the signal path of the control circuit 114 to the signal path 4, the telephone number of the emergency call center is acquired from the memory 115, and the telephone call processing to the wireless device 104 is started using the telephone number. The audio switching circuit 110 includes the wireless device 104,
A process for connecting the data communication path of the control circuit 114 is performed.

The wireless device 104 starts a process of making a telephone call to the emergency call center via a communication carrier base station or the like.

When the data communication is completed normally, the operation shifts to a voice call. The emergency call center outputs a signal to the wireless device 104 to shift to a voice call. Radio 104
When receiving the signal for shifting to the voice signal, the control unit 114 outputs to the control circuit 114 a signal indicating the shift to voice call control.

The control circuit 114 outputs a control signal for connecting the echo canceling circuit 113 and the radio device 104 to the voice switching circuit 110, and controls the echo canceling circuit 113 to perform echo canceling, howling control and the like. The signal is output, and the path of the transmission audio signal is connected.

In the case of transmission by pressing the transmission button B8,
It is also possible to prevent the harmful persons from noticing that the vehicle is transitioning to voice communication by disabling the sound of the emergency call center side, such as by not connecting the received voice signal path. .

As a means of consideration, there is a method of not outputting a sound from the center, or a method of shutting off at the emergency call terminal side.

In the case of a voice call, the transmission voice signal obtained from the microphone 12 is input to the echo cancel circuit 113. In the echo cancellation circuit 113, since it is not a two-way call, without adding signal processing to the input voice,
Output to the emergency call center via the voice switching circuit 110 and the wireless device 104.

In the case of the transmission, the mute process for the car audio 13 may be performed, but a process in which the mute is not performed is desirable. Further, by adding a process for selecting whether or not to perform the mute process by initial setting or the like, it is possible to execute a process selected in advance. Similarly, the lighting control of the indicator 9 is performed in the blue LE.
Although it is possible to perform control to indicate that the process has shifted to the emergency notification communication process by blinking D or the like, it is also possible to perform a process of prohibiting the blinking control by a selection function or the like. The voice reproduction process prohibits the voice guidance at the time of the emergency call communication process because the harmful person may be noticed.

It should be noted that the emergency call terminal device 1 periodically performs abnormality monitoring processing of each part for the purpose of ensuring reliability. The control circuit 114 detects a malfunction by outputting a periodic signal to each part and receiving a response to the signal, or monitoring voltage.

For example, in the case of monitoring the wireless device 104, an electric field strength signal periodically output from the wireless device 104 is obtained. The control circuit 114 acquires the periodic signal, and
Judge the state of. If the signal is received such that the periodic signal cannot be acquired for a certain period of time or the electric field strength cannot be secured for a long time, it is determined that the signal is abnormal and the indicator driving circuit
A control signal for instructing the indicator 9 to blink in red is output to 107, and the time at which the abnormality was detected and the contents of the abnormal state are recorded in the memory 115.

In the case of the transmission button A7 or the transmission button B8,
A configuration is provided in which different voltages or signals are output depending on states such as a normal state, a pressed state, open due to disconnection, and a short circuit. The control circuit 114 starts the transmission process when detecting a voltage indicating that the transmission button A7 or the transmission button B8 has been pressed, and instructs the indicator 9 to blink red when an abnormality such as opening or short circuit occurs. The control signal is output to the memory 115, and the time at which the abnormality is detected and the content of the abnormal state are recorded in the memory 115.

If the vehicle battery 2 is damaged due to an accident or the like and power cannot be supplied, the auxiliary battery 10
The process of generating power by the power supply from 3 is performed. According to the above process, even when the power supply from the vehicle battery 2 is interrupted, it is possible to reliably execute the emergency call notification process.

FIGS. 2 to 4 show an operation sequence of the control circuit 114 according to the first embodiment of the present invention. FIG.
5 is a sequence illustrating a normal operation of the control circuit 114. In FIG. 2, the control circuit 114 performs an airbag deployment signal 11401, a push 11404 of the send button A7, and a push of the send button B8 by polling processing or interrupt processing for the sending start.
The state of 11407 is identified.

When the airbag deployment signal is received, the information transmitted by the airbag deployment signal is recorded.
2 and implement emergency call notification processing. Similarly, the same processing is performed for the transmission button A7 and the transmission button B8 (11405, 11408).

FIGS. 3 and 4 are sequences showing the operation of the emergency notification communication process of the control circuit 114. 3 and 4
In this sequence, the processing of steps 11411 to 11417 shows the process until the control circuit 114 shifts to data communication, and is not affected by transmission conditions. Also step
The processing from 11418 is the data communication processing by the control circuit 114, and the data to be transmitted varies depending on the transmission conditions.

In the call activation determination in step 11418,
For example, in the case of the emergency call notification process using the airbag deployment signal, the transmission of the transmission by the airbag deployment signal is transmitted to the emergency report center together with the device ID and the position history data (11419). When the data communication process is completed and a transition to a voice call is made, the state shifts to a voice call state by controlling connection between the echo cancel circuit 113 and the wireless device (1142).
8).

In the case of a voice call, the transmission processing by the transmission button B8 and the transmission processing by the other transmission activation (transmission button A7) are significantly different. That is, in the case of the transmission processing using the transmission button B8, the emergency call center cannot transmit to the vehicle side that the emergency notification communication processing is being performed, so that only the transmission voice is connected to the voice line (11429, 11434). ).

In this case, since the transmission voice signal from the vehicle is transmitted to the emergency notification center and the sound processing of the reception voice signal is not performed, the emergency notification communication processing is performed to the passengers including the harmful persons on the vehicle side. The information inside the vehicle can be obtained by voice at the emergency notification center side without being discovered that the vehicle is performing the operation.

Further, by transmitting the position information by the data communication processing on a regular basis, it becomes possible for the emergency call center to grasp the trajectory of the vehicle. Also, the traveling locus of the vehicle, the current position of the vehicle, and the like can be grasped. If you do not want to switch to a voice call,
Disconnect the line without moving to 11429.

FIG. 5 is a specific example showing the internal structure of the audio switching circuit. In FIG. 5, an audio switching circuit 110 prepares three switches, and controls switching of the switches according to a control signal from a control circuit 114.

In the case of data communication processing, the wireless device 104 is connected to the voice switching circuit 110 by the switch A 1101. Also, the signal path of the switch B 1102 and the switch C 1103 is changed to the control circuit 11.
By connecting to 4, the control circuit 114 is connected to the transmission and reception audio signal paths of the wireless device 104, so that data communication processing becomes possible.

In the case of voice call processing, switch A
1101 is connected to the radio 104 side, and the switch B110 is connected.
2. Connect the switch C1103 to the echo cancel circuit 113.

When the transmission button B8 is pressed, the switch A1101 is set to G to disconnect the path of the received audio signal.
ND, switch B1102, switch C11
03 is connected to the echo cancel circuit 113.

In the state where the path of the transmission audio signal is connected by the above control, the path of the reception audio signal is disconnected, and G
Since it is possible to shift to the state of being connected to the ND, the sound from the vehicle can be transmitted to the emergency call center and the sound from the speaker 11 can be cut off, so that passengers including harmful persons in the vehicle can be found. It is possible to carry out emergency call notification processing without any processing.

When the vehicle informs the emergency call center that the button with the process of prohibiting the sounding of the sound from the emergency call center has been pressed, the harmful person will remain in the vehicle that has made the emergency call. Or because there is a high possibility that there is a thug,
The position of the vehicle and the conversation inside the vehicle may be notified to the police and the like from time to time.

(Second Embodiment) FIG. 6 is a control flow showing a process of a control circuit inside an emergency call terminal device in the configuration of an emergency call terminal device according to a second embodiment of the present invention. is there. Note that the configuration of the emergency notification terminal device itself is the same as the configuration of the emergency notification terminal device 1 according to the first embodiment shown in FIG. 1, and thus will be used as it is.

When the transmission button B8 in FIG. 1 is pressed,
The control circuit 114 is in a dangerous state such as takeover of the vehicle, and needs to execute the emergency notification communication process without being detected by the occupant. Further, since the vehicle may be moving, it is necessary to periodically execute the position information transfer processing by data communication.

When the transmission button B8 is pressed,
In, a data communication process (11443) and a voice call process using only transmission voice (11444) are performed. Step 114
When the above processing is completed in 44, the emergency call notification processing is performed again (11439).

The predetermined number of times or the number specified by the emergency call center is checked. If the number is less than the above number (11440) and if a certain period of time has passed since the previous processing (11442), the emergency call notification processing is performed. Data communication processing (11443), voice communication processing using only transmitted voice (1144)
Perform 4). When the specified number of times has been completed, or when the emergency has ended and the emergency call center does not need to obtain the next information, the emergency call processing is ended and the state is shifted to the normal state (11441, 11439).

In the first embodiment and the second embodiment, the emergency call is started by the button. However, in addition to the button, the emergency call can be started by using a voice, or boarding by the camera. An emergency call may be started by pattern recognition of a specific expression of a person.

[0066]

As is apparent from the above, according to the present invention, by providing a plurality of emergency call transmission buttons for performing the emergency call transmission processing, when a certain emergency call transmission button fails, By making it possible to perform outgoing call processing by operating another emergency call outgoing button, or by providing a difference in emergency call processing for each emergency call outgoing button, normal emergency call contact processing can be performed with a specific emergency call outgoing button operation By operating another emergency call transmission button, it is possible to execute the emergency call communication process without being detected by the passenger.
