Description

Emergency call system

The present invention relates to an emergency notification system that performs emergency notification to an emergency notification center when a vehicle accident occurs.

There is known a system for notifying an emergency call center from a vehicle when a collision of the vehicle occurs {Japanese Patent Laid-Open No. 2010-244167 (hereinafter referred to as JP2010-244167A)}. In this system, when the vehicle (12) collides with a pedestrian, pedestrian accident information specifying the situation at the time of the pedestrian collision is reported to the emergency call center {emergency call server (14)} while the vehicle is When a danger occurs in the occupant due to the collision of (12), the emergency notification center is notified of occupant accident information specifying the situation at the time of the danger occurrence of the occupant. Therefore, in the emergency call center, it is possible to know whether the collision accident is a pedestrian accident or a passenger accident or both, and it is possible to grasp the situation of each of the pedestrian accident and the passenger accident in more detail. (JP2010-244167A [0046]).

In the above-mentioned conventional emergency notification system, in order to make a notification from the vehicle to the emergency notification center, it is essential to mount (on-vehicle) a transmitting device including a telephone module connectable to a mobile communication network in the vehicle. However, in general, in-vehicle devices have strict requirements for environmental performance such as external air temperature resistance and vibration shock resistance, the transmission device becomes expensive, and as a result, there is a problem that the emergency notification system of vehicles is difficult to spread. is there.

On the other hand, a mobile information terminal such as a mobile phone or a smart phone and a navigation information center are linked (linked) by communication, and a position detection function such as a GPS function of the mobile terminal is utilized on the display device of the mobile terminal. Services for providing route guidance (navigation) are known.

By bringing such a portable terminal into a vehicle, the map on the display device of the portable terminal follows a change in the current location of the vehicle. It is possible to assist the driver while looking at the map and provide route guidance. In particular, when the navigation information center adopts a system configuration that contributes to the navigation of other vehicles by acquiring travel information from a plurality of vehicles, it is possible to quickly guide a route avoiding a crowded road or the like. Convenience becomes high from becoming.

Recently, a vehicle is equipped with a display audio device which is a product obtained by adding a display function (display device) to a car audio. This display audio device can be supplied at relatively low cost because it does not have map data as compared to the navigation device.

Therefore, the display audio device is connected to the display audio device in a wired or wireless manner, and the display audio device is configured to transfer the map (image) of the navigation from the mobile terminal to the display device of the display audio device. It is conceivable to use as a navigation device.

In this case, it is conceivable to link the display audio device connected to the portable terminal and the on-vehicle safety device such as an air bag system, and to automatically notify the emergency notification center when an accident occurs.

If an emergency notification application having a function of automatically notifying the emergency notification center is installed on the portable terminal in order to perform automatic notification, the on-vehicle safety device such as an airbag system detects an accident of the vehicle. It is considered that an emergency notification can be automatically made to the emergency notification center from the display audio device notified from the in-vehicle safety device to the display audio device and receiving the notification from the display audio device through the emergency notification application of the portable terminal. Be

However, the emergency notification application of the mobile terminal is an application that is rotated to the back (background) and resident since being installed on the mobile terminal, and depending on the OS (operating system) of the mobile terminal, Since the stop process of the back side application is periodically performed by the OS, the emergency notification application that has been resident (started up) on the back side may be automatically put into a stop state (non-start state).

However, as described above, when the emergency notification application that has been resident (activated) on the back side is automatically stopped (non-activated), the display audio device eventually passes through the mobile terminal. Will not be able to make the emergency call.

The present invention has been made in consideration of the above techniques and problems, and that an emergency notification is issued from the vehicle to an external device such as an emergency notification center at the occurrence of a vehicle accident, and from the vehicle at the occurrence of a vehicle accident. It is an object of the present invention to provide an emergency notification system capable of avoiding as much as possible a situation where an emergency notification can not be made to an external device such as an emergency notification center.

The emergency notification system according to the present invention comprises an accident detection unit for detecting an accident of a vehicle, an emergency notification processing unit for transmitting an emergency notification command when the accident detection unit detects an accident, and the emergency notification processing unit. And a portable terminal storing an emergency notification application for transmitting accident information to the outside when the emergency notification instruction is received.

According to the present invention, it is possible to make an emergency call from the vehicle to an external device such as an emergency call center when an accident of the vehicle occurs.

In this case, the emergency notification processing unit monitors the activation state of the emergency notification application of the mobile terminal and performs different emergency notification processing according to the activation state of the emergency notification application, thereby causing a vehicle accident. It is possible that a situation where it is not possible to make an emergency call outside the emergency call center etc. via a mobile terminal brought into the vehicle from a vehicle equipped with an emergency call processing unit that carries out an emergency call process when an emergency occurs Can be avoided.

Further, the emergency notification processing unit is configured to, when the emergency notification application is activated, start an emergency notification to the outside to the display device mounted on the vehicle or the display device of the portable terminal. When the button is displayed, and the emergency notification application is not in operation, the user performs an emergency notification outside the emergency notification center or the like by displaying that the emergency notification can not be made on the display device mounted on the vehicle. It is possible to avoid the situation that can not be done.

Furthermore, the portable terminal is another application different from the emergency notification application and the emergency notification application for transmitting the accident information to the outside when the emergency notification instruction is received from the emergency notification processing unit. Both or only one of the emergency notification applications is stored, and the emergency notification processing unit, when only the emergency notification application is stored in the portable terminal, the emergency notification application The activation state is monitored, and different emergency notification processing is performed according to the activation state of the emergency notification application, and when the emergency notification application and the other application are stored in the mobile terminal, the activation of the other application Monitor the status of the other application Configured to perform different emergency notification processing according to the activation state.

According to the present invention, when only one of the emergency notification applications is stored in the portable terminal, the on-vehicle emergency notification processing unit monitors the activation status of the emergency notification application, and the activation status of the emergency notification application. While performing different emergency call processing depending on the situation, if the mobile terminal stores both the emergency call application and another application, monitor the activation state of the other application; Since different emergency notification processes are performed according to the activation state, a vehicle equipped with an emergency notification processing unit that performs an emergency notification process when a vehicle accident occurs is transmitted via the portable terminal brought into the vehicle , It is possible to avoid as much as possible the situation where it is not possible to make an emergency call outside the emergency call center etc.

Furthermore, the portable terminal can start the emergency notification application and the emergency notification application for transmitting the accident information to the outside when the emergency notification instruction is received from the emergency notification processing unit. When an application is stored, the emergency notification processing unit monitors the activation state of the other application of the portable terminal, and performs different emergency notification processing according to the activation state of the other application, a vehicle accident It is possible that a situation where it is not possible to make an emergency call outside the emergency call center etc. via a mobile terminal brought into the vehicle from a vehicle equipped with an emergency call processing unit that carries out an emergency call process when an emergency occurs Can be avoided.

Here, when the emergency notification application and the other application are stored in the mobile terminal, the emergency notification processing unit determines that the emergency notification application from the other application is being started when the other application is running. To automatically transmit accident information to the outside, and when the other application is not in operation, monitor the activation state of the emergency notification application of the portable terminal, and Since different emergency processes are performed according to the movement state, it is possible to prevent a situation where the user can not make an emergency call to the outside such as an emergency call center.

According to the present invention, in order to avoid a situation where emergency notification can not be made to the outside of the emergency notification center or the like when a vehicle accident occurs, different emergency according to the activation state of the emergency notification application stored in the portable terminal Since the notification process is performed, it is possible to avoid as much as possible the situation where the emergency notification can not be made outside the emergency notification center or the like.

In this case, the portable terminal can start another emergency notification application for transmitting the accident information to the outside when the emergency notification instruction is received from the emergency notification processing unit and another emergency notification application. An application is stored, and the mobile terminal, upon receiving the emergency notification instruction from the emergency notification processing unit, activates the emergency notification application from the other application to make an emergency notification. Thus, when the portable terminal brought into the vehicle receives the emergency notification instruction from the on-vehicle emergency notification processing unit at the occurrence of an accident of the vehicle, the emergency notification application is not running. Even in this case, since the emergency notification application is activated from the other application being activated, emergency notification can be made to an external emergency notification center or the like via the activated emergency notification application.

Therefore, even when the emergency notification application of the portable terminal is not activated at the occurrence of an accident of the vehicle, the emergency notification application is activated, so that the emergency notification is issued from the vehicle to an external device such as an emergency notification center. It is possible to avoid emergency situations as much as possible and to make an emergency call reliably to external devices such as an emergency call center.

In fact, in the mobile terminal, for example, even when the emergency notification application is turned to the back and is activated in the so-called background, the background application is periodically performed by the built-in OS (operating system) of the mobile terminal. According to the present invention, the emergency notification application can be activated by another application that is being activated, even if it may be ended, even if it is ended and put into a non-activated state as such. Since the system is configured, it is possible to make an emergency call to the outside.

In addition, if the navigation application is activated on the mobile terminal in the vehicle at the occurrence of an accident by using the other application as the navigation application, the emergency notification application is not activated even if the navigation application is activated. Also, since the emergency notification application is activated by the navigation application, the occurrence of an accident can be urgently notified to the external emergency notification center or the like through the emergency notification application of the portable terminal.

The display device may further include a display device that acquires information related to the navigation application (navigation information) from the mobile terminal and displays the acquired information related to the navigation application. In this way, since the display device provided for the other purpose in the vehicle can be used as an on-vehicle navigation device, the added value of the display device can be increased. In other words, the on-vehicle navigation device can be configured inexpensively.

According to the present invention, when the mobile terminal brought into the vehicle receives an emergency notification instruction from the on-vehicle emergency notification processing unit at the time of occurrence of the vehicle accident, the emergency notification application of the mobile terminal is not running. Even if the emergency notification application is activated from another application being activated on the portable terminal, and the activated emergency notification application is used, an external emergency from the emergency notification processing unit via the portable terminal Since emergency notification can be made to the notification center etc., it is possible to avoid as much as possible the situation where emergency notification can not be made from the vehicle to an external device such as an emergency notification center at the occurrence of an accident of the vehicle. It is possible to make an emergency call reliably to
