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