A process for making a call to a center having jurisdiction over the emergency call system, such as the police or emergency call center corresponding to the telephone number via the telephone number, is performed.

The control unit 12 is composed of a microcomputer, and an interrupt signal input from an emergency call transmission button button 3 is connected to an interrupt signal input terminal. When the vehicle stops and the user turns off the ignition switch 6, the control unit 12 shifts to a sleep mode with low power consumption. In the sleep mode, the control unit 12 is supplied with the minimum power for monitoring the interrupt signal from the emergency call transmission button 3.

FIG. 2 is a flow chart for explaining a mode transition operation between a sleep mode and a normal emergency notification processing mode and an emergency notification communication processing operation in the emergency notification system terminal device of the present embodiment. In the flow of FIG. 2, when the ignition switch 6 is turned on in a processing step (hereinafter simply referred to as a step) ST1 (step S1).
T1), the emergency notification system terminal device 1 which has been in the sleep mode is released from the sleep mode, and shifts to a normal emergency notification processing mode (step ST2). In the state of the normal processing, the control unit 12 sets the emergency call transmission button 3
It is checked whether or not an emergency call signal has been input (step ST3). If no emergency call signal has been input, the ignition switch 6 is monitored next, and it is determined whether or not the power of the ignition switch 6 has been turned off. Check (step ST4). On the other hand, in the input check of the emergency notification signal from the emergency notification transmission button 3 in step ST3, when it is detected that the user has pressed the emergency notification transmission button 3 for manual emergency notification communication processing, the control unit 12 performs the emergency notification. The communication means 11 is activated to execute an emergency call notification process (step ST5), and then the step ST5 is executed.
Then, the process proceeds to a check process of turning off the power of the ignition switch 6. If the ignition switch 6 is not turned off, the process returns to step ST3 to check whether an emergency call signal has been input from the emergency call transmission button 3. On the other hand, if it is detected in step ST4 that the ignition switch 6 has been turned off, the normal emergency call processing mode is released and the mode is shifted to the sleep mode, the clock of the control unit 12 is stopped, and the processing is terminated. .

In the above description of the operation, when the power of the ignition switch 6 is turned on, the emergency call system terminal device 1 which has been in the sleep mode is released from the sleep mode (step ST1). As a trigger for releasing sleep mode,
In addition, it can be performed by turning on an accessory switch.

FIG. 3 is a flow chart for explaining an interruption processing operation to the emergency call communication processing mode in the sleep mode of the emergency call system terminal equipment of the present embodiment. In the flow of FIG. 3, when the emergency call transmission button 3 is pressed for the emergency call system terminal device 1 that has been in the sleep mode (step ST <b> 11), this triggers the emergency call system terminal device 1. The sleep mode is released, and the mode shifts to the emergency call communication processing mode by interruption (step ST12). Then, the control unit 12 immediately activates the emergency report communication means 11 when the mode is shifted to the emergency report communication processing mode, executes the emergency report communication processing (step ST13), and thereafter ends the emergency report communication processing operation by a series of interrupts. I do.

As described above, according to the present embodiment, in the event of an emergency such as a traffic accident or sudden illness, the center that has jurisdiction over the emergency call system, such as the police or the emergency call center, is provided with the current vehicle position information, registered vehicle, etc. In an emergency call system terminal device having a function of automatically starting transmission of data of an emergency call system, an output signal from an emergency call transmission button used at the time of manual emergency call notification is input to an interrupt signal input of a control unit constituted by a microcomputer. By connecting to the terminal, even if the control unit is in the sleep mode to reduce power consumption, the control unit consisting of the microcomputer is shifted to the emergency call communication processing operation by the interrupt input signal from the emergency call transmission button The emergency call transmission process can be started.

[0022]

As is apparent from the above description, according to the emergency call system according to the present invention, the terminal device of the emergency call system is set to the sleep mode in which the power consumption is reduced when the engine is stopped due to turning off the ignition switch. Even in the case of the transition, the control unit including the microcomputer can be shifted to the emergency report communication processing operation by the interrupt input signal from the emergency report transmission button, and the emergency report transmission processing can be started immediately.
