PURPOSE:To prevent the delay in the operation of an air bag at the time of a high speed collision by operating the air bag when the deformation speed from a deformation speed sensor is above a defined value while operating same based on the acceleration from an acceleration sensor when below the defined value. CONSTITUTION:At the time of the collision of a vehicle, when a deformation speed from a deformation speed sensor 14 is above a defined value (a), an air bag 16 is operated. When the deformation speed from the speed sensor 14 is below the defined value (a) while an acceleration from an acceleration sensor 12 at this time being above a defined value (b), the air bag 16 is operated. Next, as the acceleration from the acceleration sensor 12 is below the defined value (b), this time, the air bag 16 is not operated. Thus, the time required for the air bag 16 to operate when the deformation speed from the speed sensor 14 is above (a) is, e.g., 0-5m/sec. and, thus by making the time, e.g., below 5m/sec., the delay in operation of the air bag 16 can be prevented even at the time of collision at a high speed. |
