Next, processing performed by the emergency call device will be described with reference to FIG.
FIG. 3 is a flowchart of processing in the event of a vehicle emergency in the emergency call system according to the embodiment of the present invention.

The process of FIG. 3 is started and repeated when the ignition of the vehicle 1 is turned on and the emergency call device 10 is powered on.
After the start of the process, in step S10, when the vehicle emergency signal a1 (collision detection signal) is output from the airbag ECU 19 or the vehicle emergency signal a2 is output from the manual notification switch 17 by the operation of the occupant, in step S11 The emergency call device 10 receives the vehicle emergency signal a1 or a2. In response to the reception of these signals, various processes in the event of a vehicle emergency are executed.

When the vehicle emergency signal a1 or a2 is received, in step S12, the control unit 11 of the emergency call device 10 controls the radio communication unit 15 using the communication address of the emergency call center 2 stored in the storage unit 16. A wireless communication link is established with the emergency call center 2 and emergency information is transmitted to the emergency call center 2. This emergency information includes information indicating that the vehicle is in an emergency (specifying one of the vehicle collision and the manual notification switch 17 operation), current position information, vehicle identification information, and the like. Further, the emergency information may include other vehicle information (such as the communication address of the emergency call device 10).
When emergency information is transmitted from the emergency call device 10 to the emergency call center 2, the emergency call center 2 sends information on the vehicle 1 (for example, current position information of the vehicle 1, vehicle identification information, a communication address of the emergency call device 10 (telephone). Number, e-mail address, etc.) are transmitted to the communication device 60 of the emergency vehicle 6. Thereby, a signal can be transmitted from the communication device 60 to the emergency notification device 10.

Next, in step S13, the emergency call device 10 and the emergency call center 2 can perform a voice call using the wireless communication link established in step S12.
Specifically, upon receiving the emergency information, the emergency call center 2 identifies the vehicle 1 based on the vehicle identification information included in the emergency information and the communication destination address accompanying the emergency information, and the vehicle information of the vehicle 1 etc. Is displayed on the display device, and voice communication (voice call) processing is performed with the emergency call device 10 of the vehicle 1 via the wireless communication link. Thereby, the passenger | crew of the vehicle 1 can perform the voice call by radio | wireless communication with the operator of the emergency call center 2 via the radio | wireless communication part 15 of the emergency call apparatus 10 using the microphone 13a and the speaker 13b in a vehicle. It becomes.

  Next, in step S <b> 14, the control unit 11 of the emergency call device 10 determines whether or not the voice call between the emergency call device 10 and the emergency call center 2 has ended. As a result, when the voice call has not ended, the process waits until the voice call ends.

On the other hand, when the voice call between the emergency call device 10 and the emergency call center 2 is finished, the process proceeds to step S15, and the control unit 11 of the emergency call device 10 receives the sound generation signal via the wireless communication unit 15. It is determined whether or not. The sound generation signal is an alarm sound output signal for instructing output of an alarm sound by the horn 21a and / or the alarm 21b of the vehicle 1.
For example, when the emergency vehicle 6 reaches the vicinity of the current position of the vehicle 1 based on the current position information of the vehicle 1, the communication device 60 of the emergency vehicle 6 responds to the operation of the emergency vehicle 6 by the occupant of the emergency vehicle 6. A sound generation signal is transmitted to the communication address. When the wireless communication unit 15 receives this sound generation signal via the base station 3 or the communication network 4, the control unit 11 determines that the sound generation signal has been received.

  As a result, if a sound generation signal is received in step S15, the process proceeds to step S16, and the control unit 11 outputs a message from the speaker 13a via the sound processing unit 13 to start the operation of the horn 21a and the alarm 21b. Let At this time, the control unit 11 may display a message on the display of the vehicle 1 to start the operation of the horn 21a or the alarm 21b.

  Next, in step S17, the control unit 11 outputs a signal to the BCM 20 to activate the horn 21a and / or the alarm 21b. In response to this, the BCM 20 activates the horn 21a and / or the alarm 21b to output an alarm sound.

  Next, in step S18, the control unit 11 determines whether or not a predetermined time (for example, 30 minutes) has elapsed since the notification of the emergency information, and the remaining capacity of the vehicle battery 18 is a predetermined value (for example, SOC is 20%). It is determined whether or not. Here, “when emergency information is notified” means, for example, when the emergency notification device 10 receives the vehicle emergency signal a1 or a2 in step S31, or the emergency notification device 10 transmits emergency information to the emergency notification center 2 in step S32. When it is sent to.

As a result, when the predetermined time has not elapsed since the emergency information was notified and the remaining capacity of the vehicle battery 18 is not less than the predetermined value, the control unit 11 passes the predetermined time from the emergency information notification. Or it waits until the remaining capacity of the vehicle battery 18 becomes a predetermined value or less.
On the other hand, if the predetermined time has elapsed since the emergency information was reported or the remaining capacity of the vehicle battery 18 is less than or equal to the predetermined value, the process proceeds to step S19, and the control unit 11 operates the horn 21a and / or the alarm 21b. Is output to the BCM 20. In response to this, the BCM 20 stops the operation of the horn 21a and / or the alarm 21b. Thereafter, the emergency call device 10 ends the process.

If no sound generation signal is received via the wireless communication unit 15 in step S15, the process proceeds to step S20, and the control unit 11 determines whether or not a predetermined time (for example, 30 minutes) has elapsed since the emergency information was reported. And whether or not the remaining capacity of the vehicle battery 18 is a predetermined value (for example, SOC is 20%) or less is determined.
As a result, when the predetermined time has not elapsed since the emergency information was reported and the remaining capacity of the vehicle battery 18 is not less than or equal to the predetermined value, the control unit 11 continues to execute the process of step S15.
On the other hand, in step S20, when a predetermined time has elapsed since the emergency information was reported or when the remaining capacity of the vehicle battery 18 is equal to or less than a predetermined value, the emergency notification device 10 ends the process.

Next, further modifications of the embodiment of the present invention will be described.
In the above-described embodiment, when the horn 21a and / or the alarm 21b is operated, the control unit 11 has passed a predetermined time since the emergency information was reported or the remaining capacity of the vehicle battery 18 is predetermined. Although it has been described that the operation of the horn 21a and / or the alarm 21b is stopped when the value is equal to or less than the value, the operation of the horn 21a and / or the alarm 21b may be stopped based on a different condition.
For example, when a stop switch (not shown) provided in the emergency call device 10 is operated, a signal (alarm stop signal) for instructing to stop the horn 21a and / or the alarm 21b is output from the stop switch. When the control signal (warning stop signal) for instructing the stop of the horn 21a and / or the alarm 21b is received from the communication device 60 or the like of the emergency vehicle 6, the horn 21a and / or the alarm 21b is activated by the BCM 20. May be stopped.

  Further, in each of the above-described embodiments, the alarm sound output unit 21 has been described as including the horn 21a and the anti-theft alarm 21b. However, the alarm sound output unit 21 may include only the horn 21a or the alarm 21b, or the horn 21a and the alarm 21b. A device other than 21b may be included.

  Next, the effect of the emergency notification device according to the above-described embodiment of the present invention and the modification of the embodiment of the present invention will be described.

  First, when the vehicle 1 is in an emergency, the control unit 11 of the emergency notification device 10 receives a sound generation signal instructing the output of an alarm sound, so that the horn 21a and / or the alarm 21 is output. Alternatively, since the alarm 21b is controlled, for example, when the emergency vehicle 6 is difficult to find the vehicle 1 immediately in an emergency such as when the vehicle 1 slides into a valley in a mountainous area where there is little traffic or traffic, the emergency vehicle 6 When the communication device 60 transmits a sound generation signal to the emergency call device 10 according to the operation of the occupant of the vehicle, a loud sound can be output by the horn 21a or the alarm 21b of the vehicle 1, The emergency vehicle 6 can easily find the vehicle 1.

  Moreover, since the control part 11 controls the horn 21a and / or the alarm 21b so that a warning sound is output when the voice call with the emergency call center 2 is terminated in the event of a vehicle emergency, the emergency call device 10 It is possible to prevent the voice call from being hindered by outputting a warning sound by the horn 21a or the alarm 21b in spite of the voice call between the emergency call center 2 and the emergency call center 2.

  In addition, the control unit 11 outputs an alarm sound when a predetermined time has elapsed since the emergency information was reported or when the remaining capacity of the vehicle battery 18 that supplies power to the emergency notification device 10 is less than or equal to a predetermined value. Since the horn 21a and / or the alarm 21b are controlled to stop the alarm, the power consumption of the vehicle battery 18 due to the horn 21a and the alarm 21b outputting an alarm sound can be limited. And power for wireless communication between the emergency call center 2 can be held.

  In addition, when an alarm stop signal instructing to stop the output of the alarm sound is input, the control unit 11 controls the horn 21a and / or the alarm 21b so as to stop the output of the alarm sound. When it becomes unnecessary, the passenger of the vehicle 1 operates a stop switch provided in the emergency notification device 10 to output an alarm stop signal, or the passenger of the emergency vehicle 6 from the communication device 60 or the like of the emergency vehicle 6 The horn 21a and the alarm 21b can be stopped by transmitting an alarm stop signal.

  Moreover, since the warning sound output unit 21 includes the horn 21a and / or the alarm 21b, an existing device in the vehicle 1 can be used as the warning sound output unit 21, and an increase in cost and an increase in the number of parts are suppressed. be able to.
