PURPOSE:To prevent erroneous operation even an rough road as well as at high speed oblique collision and pole collision by providing an AND means to which bath start signals from the first and second comparison means are given and which then outputs start signal to a trigger circuit. CONSTITUTION:The results of blacks 15 and 16 are, through a block 17 which is a connection means, supplied to an AND circuit 36, and at the same time, the result of a block 37 is also supplied to the AND circuit 36. The AND circuit 36, when both signals from the blacks 17 and 37 are supplied, outputs start signal to a trigger circuit 5. With this, by the first and third comparison means 15 and 37, ordinal high speed oblique collision and pale collision are distinguished from low speed head-on collision, so that collisions with cars of low body rigidity are decided early. Further, by the second comparison means 16, erroneous operations on rough road are prevented. |
