Abstract

In an electronic safety device for vehicle occupants including an acceleration-sensitive sensor, a control unit, and a plurality of inertial restraining devices with associated output stages, a reliable operating mode is guaranteed for the safety device by storing characteristic fault conditions, together with control strategies compensating for these fault conditions. In the event of a fault, the safety device applies the respective, assigned control strategy to activate the restraining devices.
