In addition, the vehicle airbag system is a safety device that mitigates the impact of the passenger by the airbag cushion by inflating the airbag cushion like a balloon in the event of a crash of a certain size and prevents the passenger from being knocked out of the vehicle body. Driver Air Bags and Passenger Air Bags to protect, Side Air Bags and Curtain Airbags to protect the passenger's side in the event of a side impact.

In general, the airbag cushion is installed to protect the face and chest of the occupant during the collision of the vehicle, such an airbag is usually designed and mounted based on the standard body of the adult male.

Airbags are used in vehicles to enhance and supplement the protection provided by the seat belts. The combination of the seat belt and the air bag is most effective when it is possible to determine whether the seat belt is actually used.

When the seatbelt is filled, the deployment of the airbag exerts maximum effect to protect the occupant wearing the seatbelt.

The reduced passenger seat airbag (LRD) according to the prior art is designed to mitigate the impact of the airbag in order to reduce the injuries that children under 6 years of age in the passenger seat and the elderly may suffer from shock when the airbag is deployed. Or a state-of-the-art airbag system that distributes the deployment direction from side to side.

The passenger seat airbag device according to the prior art reduces injuries of the passengers mainly by suppressing the blackout of the center portion, but reduces the injuries even when the passengers are in an out of position, as well as in the middle and left and right. It should be possible, but the conventional injury reduction passenger seat airbag is difficult to achieve a satisfactory performance in this case, there is a problem in controlling the airbag cushion deployed to the left and right.

In addition, in the case of a passenger having a body shape that is out of the reference body type as described above, the airbag cushion is not optimally protected, and in some cases, the airbag cushion may be rather injured.

The vehicle safety device according to the embodiment is to determine the acceleration value, whether the passenger seated on the seat, whether the seat belt is worn by the passenger, and the seat position according to the vehicle collision, thereby determining the deployment strength of the airbag and whether the belt is pulled accordingly. It is done.

And a third sensing unit, a sensor unit sensing an acceleration value of the vehicle, and an electronic control unit configured to determine the airbag deployment intensity when the vehicle crashes based on values calculated through the first and second signals, the position value, and the acceleration value. do.

The automobile safety device according to the embodiment does not need to replace the system for each vehicle type by determining an output value according to various input values.

The vehicle safety apparatus according to the embodiment may minimize the injury of the passenger by adjusting the deployment strength of the airbag according to various input values.
