OCCUPANT SENSING AND CRASH BEHAVIOR SYSTEM

摘要

PURPOSE: An occupant sensing and crash behavior system is provided to control a length of seat belt and air bag by sensing a position of rider when a vehicle is crashed. CONSTITUTION: An occupant sensing and crash behavior system for a motor vehicle determines the presence and location of an occupant to then control the deployment of supplemental restraint systems such as air bags or inflatable seat/shoulder belts. Pre-crash sensor, system controller, crash anticipation and crash severity sensors provide additional inputs to the system to determine the behavior of the crash and the occupants therein. An infrared sensor emits a plurality of beams to determine the location and position of the occupant as does a proximity sensor located on the air bag door or the occupant seat. Occupant weight plus the presence and orientation of a child seat are considered. Seat belt control is provided to control the length of the seat belt during an impact or crash.
