Sichtbasiertes Insassenklassifikationsverfahren und System für die Steuerung der Gassackentfaltung in einem Fahrzeugrückhaltesystem

摘要

A vehicle restraint system (20) has a vision-based occupant classification system (48) for control of airbag deployment during a crash scenario. The classification system utilizes two imaging sensors (52, 54) which together create a stream of paired images (84) received and stored by an occupant classification controller (46). A computer program product (62) of the controller utilizes the paired images (80, 82) to extract disparity/range features (68) and stereo-vision differential edge density features (64). Moreover, the controller extracts wavelet features (66) from one of the two paired images. All three features or maps are classified amongst preferably seven classifications by algorithms of the computer program product producing class confidence data 114 fed to a processor (117) of the controller for processing and output of an airbag control signal (50) input into a restraint controller (32) of the vehicle restraint system.
