PURPOSE:To provide a control system capable of quickly actuating a safety device even initial period deceleration is small like a center pole collision. CONSTITUTION:This system is provided with an integration circuit 4 integrating the signal of an acceleration sensor 1 like a normal control system, and a collision judgment circuit 5 judging collision based on the output of the integral circuit 4 to turn on a transistor 8. Moreover a bandpass filter 9 through which the acceleration component of a special frequency band of 200-300Hz can be passed and a threshold adjusting circuit 11 are provided. In the threshold adjusting circuit 11, the threshold level of the collision judging circuit 5 is lowered following the increase of an acceleration component having passed the band-pass filter 9 to hasten the ON-action of a transistor 8, and in its turn, the ignition of a squib 7. |
