摘要:
In a method and apparatus for activating vehicle-occupant protection devices, an approach speed to a collision object is determined within a predefined proximity range of the vehicle surroundings. If the approach speed is above a threshold value, an anticipated impact time for a collision with the object is determined. A time range is determined on the basis of the anticipated impact time, a signal quality of at least one proximity sensor, driving dynamics and the geometry of a collision object being taken into account in this time range. The assigned vehicle-occupant protection devices are activated after occurrence of a positive plausible-confirmation check within the time range.
