Abstract
A passenger protection system is triggered directly at least when a second stage is reached among at least two different stages of an accident hazard an/or accident force, determined in accordance with sensor signals. Already when a first accident hazard and/or accident force stage is reached, at least an indirect trigger command is sent to individual passenger protection systems, a specified time interval is started, and, in the event of the second accident hazard and/or accident force stage not being reached within the specified time interval, a cancel command is sent to cancel the indirect trigger command. On receipt of such an indirect trigger command the passenger protection systems also start a relevant time interval, and in the event of the cancel command not being received on expiry of the relevant time interval, they automatically activate the triggering of the passenger protection systems.
