A preventatively acting safety system for a motor vehicle comprises safety devices which are actuated as a function of information which is recorded by a driving situation detection device by means of a driving state sensor system and is evaluated in a data evaluation device. The recorded information are compared with at least one triggering threshold value and the safety devices being actuated when the triggering threshold value is exceeded. The triggering threshold value is adapted as a function of a total vehicle acceleration and a vehicle speed, to correspond to a degree of danger felt by a vehicle occupant.

Motor vehicle having a preventatively acting safety system

A motor vehicle, such as a passenger car, having a preventive action protection system is provided, which includes safety devices which are actuated as a function of features which are based on input variables from a safety sensor system in a data evaluation and control device, wherein, when a critical driving state is detected, the data evaluation and control device actuates at least one safety device which is assigned to the driving state. The features are each assigned a specific weighting relating to the criticality of the driving state.

In a method for controlling the operation of a reversible belt retractor to release a belt extraction lock of a restraint belt in a motor vehicle, the lock can be activated by an acceleration sensor. After the belt retractor has been triggered as a consequence of a hazardous situation having been detected and after the hazardous situation has been recognized as being over, the operation of the belt retractor is controlled by a release signal at a release time in order to bring about the release of the belt extraction lock to shift it from a blocking state into a comfort-providing state. The release time is determined by a sensor model algorithm based on a model of the acceleration sensor from at least one variable characterizing the running dynamics.
