で、衝突のエネルギーを緩和する。As a means for solving the above-mentioned problems, the present invention relates to a vehicle which has a low pressure inside a bonnet in front of a cabin in a midship vehicle. A vehicle airbag in a deployed state is mounted, and when the impact of a collision reaches the vehicle airbag, a change in pressure is determined and the vehicle is deployed. In addition, in the vehicle airbag mounted on both front sides of the vehicle, the obstacle is determined by the difference in the impact pressure whether the obstacle is a vehicle, a telephone pole, or a pedestrian or a small animal. The energy of the collision is reduced by applying pressure and deploying and reducing the pressure of the exhaust gas.
