An occupant sensor system of a vehicle and an operation method by sensor fusion (Automotive occupant sensor system and method of operation by sensor fusion)

摘要

The present invention provides an enable,. Position and type classification of an occupant of a passenger seat of an automobile for use in controlling an airbag activator control system associated with controlling an inflation rate or an inflation rate of an airbag, To a system for sensing the presence of a child seat. This sensor system uses a method of combining the information provided by two or more sensors 24, 26 " seeing " the sensor fusion, each with a unique sense of the world. In a preferred embodiment, the infrared sensor input 78 and the supersonic sensor input 79 are combined by a sensor fusion algorithm 80 to provide an occupancy status output signal 85 to the airbag controller.
