Abstract
In a control system for actuating a vehicle air-bag, a data representing change in the detected vehicle speed is calculated on the basis of the acceleration sensed by a vehicle acceleration sensor. The data is compared with a reference signal depending upon a temperature relating to that of an actuating member of the air-bag to discriminate whether or not the change in the detected vehicle speed has reached a level determined by the reference signal, whereby the complete inflation of the air-bag is ensured when a collision occurs without a time delay regardless of changes in temperature.
