摘要：
The restraint system comprises a central control unit (ZS) that is connected to several data processing units (DV1, DV2) by means of a bus line (BL), each of said units being provided to control one or more restraint devices (RH1, ..., RHk). In order to ensure that the restraint system remains operational in case of faulty power supply (SV) in the central control unit, said central control unit (ZS) is switched over to the battery voltage (UBA) of the vehicle as new power supply voltage. The central control unit (ZS) then signalizes the switchover to all data processing units (DV1, DV2), whereupon all data processing units (DV1, DV2) adapt their circuits to the new power supply voltage level (UBA).
