Abstract: 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.

Abstract: The invention relates to a method for actuating a reversible vehicle occupant protection means in a motor vehicle having a driving state sensor system and a reversible vehicle occupant protection means. The reversible vehicle occupant protection means can be triggered before the collision time and as a result moved into an effective position. For this purpose, the driving state data are monitored with respect to a state of emergency braking, and when the state of emergency braking is detected the vehicle occupant protection system is actuated. In addition, a state of oversteering and a state of understeering are determined by the data processing device. The reversible vehicle occupant protection system is actuated when the data processing device detects the state of emergency braking and/or the state of oversteering and/or the state of understeering.

Abstract: A sensor element for a bus system in a motor vehicle has a first number of pins by which it can be connected to the bus lines of the bus system, having differing potentials. The first number of pins is larger than the number of bus lines. A first device measures and evaluates the potential on at least one of the pins, while a second device assigns to the sensor element a specific address coding from the measured and evaluated potentials. The invention also relates to a bus system and to a method of operating the bus system.
