Abstract
A system for controlling a safety device for a vehicle has a first and a second switching element connected in series in this order from a power source toward the ground. A condenser is interposed between a connecting point for both the first and second switching element and the ground in such a manner as to be in parallel relation to the second switching element. The actuating element for the vehicle safety device is connected in serial relation to the condenser between the connecting point and the ground. The control system further has an electric current supply control device. This electric current supply control device periodically effects ON/OFF control operations over the first and second switching elements. Each cycle for effecting the ON/OFF control operation over the first and second switching elements includes a time period where the first switching element is in the ON-state and the second switching element is in the OFF-state as well as a time period where the first switching element is in the OFF-state and the second switching element is in the ON-state. Owing to this arrangement, alternating current is supplied to a squib to actuate the vehicle safety device.
