Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic alarm system for a vehicle equipped with an airbag system, which automatically issues an alarm to the outside in the event of an accident and automatically secures the safety of a passenger. (Device) and an automatic safety assurance system (device).

As is well known, in a vehicle equipped with an airbag, when a rear-end collision or the like occurs, an airbag such as a driver's seat or a passenger seat is automatically deployed (inflated). .

[0005] FIG. 5 shows an outline of the airbag system 10. That is, the airbag 11a
It is stored in a folded state in the airbag module 11 of the handle 12, and this is an accident signal (output signal or current) from the sensor unit 13 in which a sensor for detecting an impact (G) at the time of a rear-end collision or the like is incorporated. ), The explosive in the ignition portion (not shown) of the airbag module 11 is ignited, and the airbag 11a is inflated as shown in the imaginary diagram in FIG. . Also, depending on the system,
Similar signals are transmitted to the passenger airbag and the side airbag through the branch circuit 14, and these airbags are also inflated. Of course, each airbag may have an independent sensor unit.

[0004] In any case, when the airbag is inflated due to such a rear-end collision or the like, the accident vehicle naturally becomes difficult to drive normally, or the driver or the passenger is injured, so that an appropriate accident response can be taken. May not be possible.

[0005]

However, in the case of the conventional airbag system, since the airbag simply inflates at the time of an accident, it is impossible to drive as an accident vehicle, or a driver or a passenger is injured. Assuming a case where it was difficult to deal with an appropriate accident due to factors such as this, it was still insufficient and there was room for improvement.

That is, in order to prevent a secondary accident caused by a following vehicle when an accident occurs, it is necessary to promptly notify the following vehicle of the existence of the accident vehicle. However, in the case immediately after the accident, the driver and the occupant are often mentally upset, so that it is quite difficult to appropriately issue an alarm to a following vehicle. In particular, a following vehicle that is only a distance of about several tens to several hundreds meters from the accident vehicle needs to be notified of the anomaly immediately after the accident.

Immediately after an accident, if the accident vehicle immediately turns on a hazard lamp, a turn signal lamp, or the like, the following vehicle can immediately sense (predict) an abnormality in the preceding vehicle and take measures to avoid the accident. Under such tense situations, general accident measures usually taken after an accident, such as a driver or a passenger going out of the car, placing a triangular reflective stop device behind, Obviously, burning or flashing an alarm flashlight is not enough. Of course, if the driver or the passenger is injured, such a measure is impossible.

Therefore, if a desired warning is automatically issued to a following vehicle without relying on an instantaneous operation or judgment that is considered to be quite difficult immediately after the driver or passenger's accident, the above-described secondary Accidents are prevented before they happen.

[0009] It is also very important that a driver or a passenger safely and quickly escape from the accident vehicle after the accident. For example, if a fire breaks out of the engine room after an accident, if the doors and door glass of the vehicle are left running, if the power supply system goes down and they remain closed, the driver or passenger A serious problem arises, such as escape of the ship.

[0010] Therefore, immediately after the accident, if the drive unit of the door opening / closing mechanism (locking mechanism) and the drive unit for the power window of the door glass are automatically operated and brought into the open state (open state), the escape is achieved. Dangerous situations such as delays are resolved beforehand. In addition, immediately after the accident, if the drive of the engine kill switch is turned on, even if gasoline leaks etc. have occurred due to the accident, even if the key operation such as the engine start is carelessly performed, it will not catch fire Fire can be prevented beforehand.

SUMMARY OF THE INVENTION The present invention has been made in view of such conventional problems, and has a relatively simple structure and is capable of promptly giving a warning to a following vehicle at the time of an accident in which an airbag inflates, and It is an object of the present invention to provide an automatic warning system and an automatic safety securing system in the event of a vehicle accident that enable a driver or a passenger to escape safely.
