PURPOSE:To provide an air, bag starting controller at a low cost without increasing the contact point capacity of a safing sensor over necessity. CONSTITUTION:If a large negative accelerating speed is applied on a vehicle, a collision judging means 23 detects the negative accelerating speed and outputs a collision detecting signal. At this time, a safing sensor 1 detects the contact between the electrodes 13, 14 and a contact pole 12. Since, at this time point, the output of a delaying circuit 21 is at L level, the output of an AND gate 22 becomes 'L' level, and an FET 24 is in turned-OFF state. Accordingly, no electric current flows in the electrodes 13 and 14, and the contact point is photeted. Then, in a delaying circuit 21, the output signal is set to 'H' level after the predetermined delay. Accordingly, the output of the and gate 22 becomes 'H' level, and the FET 24 is tuned ON. |
