Description of the Related Art When an emergency such as an accident or sudden illness of an occupant occurs in a running vehicle, it is necessary to promptly report the situation to a road authority, police or an emergency organization. Currently, such reports are generally made by the crew themselves or by witnesses present around them.

[0003]

However, when an emergency occurs, it is not always the case that a witness who can report the emergency is present. It is also conceivable that the occupant is not in a state where he / she can report because of physical injury or mental sway. Further, depending on the area where the vehicle is traveling, a situation is expected in which a report is delayed because there is no reporting means such as a telephone nearby.

[0004] If the notification of an emergency is delayed, the appropriate response to the situation will also be delayed. The delay caused by the emergency caused by the delay in coping increases the damage. Particularly, the delay in the treatment of the sick or injured is a problem that directly affects human life and the like. Therefore, when an emergency occurs, it is necessary to immediately notify a predetermined organization to minimize the damage caused by the emergency.

The present invention has been made in view of the above points, and has as its object to provide a vehicle emergency notification system capable of automatically and promptly reporting an emergency in the event of an emergency. Aim.

[0006]

A vehicle emergency notification system according to the present invention has a GPS method for detecting the position of a vehicle by radio waves mounted on a vehicle and emitted from an artificial satellite, or a system which is fired from a fixed position on the ground. Vehicle position detecting means for detecting the position information of the vehicle using a beacon method for detecting the position of the vehicle by radio waves, collision state measuring means for measuring the collision state of the vehicle, and collision based on the measurement data of the collision state measuring means Emergency information generating means for generating emergency information that is information on collisions such as the state of the vehicle, the degree of collision, etc., and information provided on the vehicle as a light or sound alert, and a code type coding the contents of the emergency state A mobile phone, radio, or PHS that transmits to the outside of the vehicle by either a warning or a voice or text alert that conveys the contents of an emergency by voice or text information. An information transmitting means, and a collision state is determined from measurement data of the collision state measuring means. If the degree of the collision state is equal to or more than a predetermined state, the self-vehicle position detecting means detects the collision state from the emergency information transmitting means. An emergency call control means for transmitting the vehicle position data and the emergency information generated by the emergency information generation means.

According to a seventh aspect of the present invention, in the vehicle emergency system, the emergency notification control means has transmission switching means capable of switching manually, and the occupant can arbitrarily execute or not execute the emergency information transmission. It is characterized by being selectable.

[0008] In the vehicle emergency system according to the present invention, the emergency notification control means may select the execution of emergency information transmission by the switching means without the collision state measuring means measuring the collision. In this case, the emergency information transmitting means transmits emergency information indicating that an emergency has occurred for a reason other than a collision.

BEST MODE FOR CARRYING OUT THE INVENTION

First Embodiment A first embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a block diagram illustrating the configuration of a vehicle emergency system according to the present invention. As shown in the figure, the vehicle emergency system according to the present embodiment mainly includes a collision sensor 1, 2, 3, which detects a collision due to an impact on a vehicle, a vehicle position detection device 20, a car telephone 15, and a control device for them. The control unit 10 has a memory 13 and a switch 17 which can be manually switched.

The collision sensors 1, 2, and 3 are installed at different positions from each other and detect impacts applied to different positions of the vehicle. The installation positions of the collision sensors 1, 2, 3 are, for example, as shown in FIG. 2, on a floor panel in the front center of the vehicle interior (collision sensor 3), on the left part of the front apron upper member (collision sensor 1), and on the right. (Collision sensor 2) is conceivable. The collision detection data of the collision sensors 1, 2, and 3 may be obtained, for example, by obtaining a shock due to a collision applied to an automobile as a waveform recording vibration of the automobile with respect to time. When a sensor used in an airbag system is used as the sensor, a waveform in which a negative acceleration (deceleration) applied to the vehicle with respect to time is recorded may be obtained.

The vehicle position detection device 20 may be a device dedicated to the vehicle emergency notification system according to the present embodiment, which knows the position where the vehicle is currently traveling by, for example, the GPS method by latitude and longitude. The data of the vehicle position detection of the navigation device may be diverted.

Data detected by the collision sensors 1, 2, 3 and the vehicle position detecting device 20 are all input to the control unit 10 to generate emergency information. The collision sensors 1, 2, and 3 respectively detect impacts applied to different positions of the vehicle. Therefore, the control unit 10
Based on the waveform data detected by each collision sensor and the combination thereof, it is possible to determine the collision state by identifying not only the magnitude of the force applied to the vehicle due to the collision but also the distribution state of the force and the direction in which the force was received. .

The memory 13 provided in the control unit 10 includes collision sensors 1, 2, 3 corresponding to the collision state.
Is stored. Such waveform data is experimental data obtained by performing a collision experiment in which an automobile is intentionally collided in various states. The control unit 10 compares the waveform data detected by the collision sensors 1, 2, and 3 with the waveform data stored in the memory 13, and determines the collision state corresponding to the waveform data matched as a result of the comparison with the collision state in the current collision. to decide. Further, the control unit 10 combines the obtained collision state determination data with the detection data of the vehicle position detection device 20 to obtain emergency information.

As a result of the collision state determination, if the control unit 10 determines that the impact of the collision on the vehicle or the occupant is small and there is no need for notification, no notification is made. Control unit 1
If 0 determines that a report is needed, a report is made by the car phone 15.

In the present embodiment, the emergency information transmitting means uses a car telephone. However, other than this, any transmitting means such as a wireless device, a mobile phone, and a PHS which can be mounted on a vehicle may be used.

The notification destination at this time is selected by the control unit 10 according to the collision state from among road public corporations, police, emergency fire departments, and the like. In the notification method at this time, for example, a person in charge of the notification is first alerted by the lighting of a lamp and a signal sound, and a detailed vehicle position and a collision state are displayed in characters by the selection of the person in charge.

In this embodiment, the emergency information is notified to the notification destination by means of a combination of lighting of a lamp, a signal sound, and character display. However, the notification is performed as a voice or a coded message. It may be something.

The control unit 10 is provided with a switch 17 which can be manually switched. Switch 17
Is normally in the ON state, for example, when vibrations are detected by the collision sensor such as tow truck movement and there is no need to report, or when the occupant wants to report by himself, By switching this to OFF, it is possible not to transmit the emergency information regardless of the judgment of the control unit 10.

When the occupant makes an emergency call for reasons other than a collision such as sudden illness, the switch 17 is turned off.
It is also possible to transmit emergency information by / ON. The emergency information in this case is for notifying the position of the vehicle and that no impact was applied to the vehicle when an emergency occurred.

In the above-described embodiment, the state of the collision can be determined from the data waveform of the collision sensor, and the result of this determination can be reported to the road corporation, police, emergency fire department and the like together with the position of the vehicle. The processing of this notification is automatically started by the detection of the impact due to the collision of the collision sensor. Therefore, even if the occupant is unable to make a report due to the damage of the collision, an emergency report is made to an appropriate organization, and prompt processing for an emergency can be performed.

Also, a memory for storing data relating a collision state and a data waveform of a collision sensor obtained by the collision is provided. By comparing the detected data waveform of the collision sensor with the data stored in the memory, It is possible to determine not only the presence or absence of a collision but also the collision state.

Further, by providing a switch for preventing or transmitting emergency information regardless of the judgment of the control unit, malfunction of the emergency notification system is prevented, and the emergency notification is automatically performed or performed by itself. Made it possible to choose either. Further, when it is necessary to make an emergency call for a reason other than a collision such as a sudden illness of an occupant, emergency information can be transmitted.

Second Embodiment Next, a second embodiment of the present invention will be described.
