Abstract

Increasingly, motor vehicles are being equipped with safety systems for vehicle occupants and where these safety systems are controlled by electrically actuated triggering means such as ignition pills for airbags that in turn are controlled from an output stage. The invention demonstrates a method that ensures safe and uninterrupted operation of these triggering means and which protects the output stage from being destroyed should a fault occur as a result of, for example, an ignition pill by-pass.
