Zusammenfassung:	A method for operating a pre-crash sensing system for a vehicle having an object detecting system and an associated data storage. The method includes partitioning the vehicle operating environment into a plurality of zones wherein each zone represents a different area surrounding the vehicle. In response to detecting an object within any one of the zones, the method activates the zone, and modifies an state of the object detection system and the contents of,the data storage as a function. the active zone. In one embodiment, three zones are disclosed wherein each zone represents a spheroidal area surrounding the vehicle. When the furthest zone is active, all data within the data storage is given approximately equal processing priority. When the middle zone is active, the content of the data storage is modified to prioritize data regarding the detected object for processing. Finally, when the nearest zone is active, the content of the data storage is further modified to provide highest priority to data regarding the detected object.
