Abstract
The present invention provides an air-bag control apparatus wherein, when an air-bag sensor detects a car collision, a switching gate passes on a modulation signal originated from a signal generation means to a first modulation circuit which modulates a carrier received from a first-carrier generation means in accordance with a pattern of the modulation signal. A modulated carrier obtained as a result of the modulation is received by a first demodulation circuit which demodulates the modulated carrier to produce a demodulated signal supplied to a signal comparison circuit. The signal comparison circuit compares the demodulated signal with the modulation signal received from the signal generation means. Only if the demodulated signal matches the modulation signal is an activation signal output for activating the air-bag unit.
