ABSTRACT:
A control system for a vehicle safety device comprises an operation circuit in which a main switching element, an activator, and a safety switch are connected, in series, to a condenser for accumulating electric power. When a vehicle collision has occurred, the safety switch is turned on and the main switching element is turned on in response to a vehicle collision judgment which is made in accordance with a signal from an acceleration sensor. As a result, electric current is supplied to the activator to activate the vehicle safety device. The main switching element is turned off when a time period where an output of an operation instruction signal for actuating the main switching element and the ON-state of the safety switch are realized reaches a preset time period.
