Abstract: | The need for an embedded system that can fuse incomplete, inconsistent, and imprecise decisions from several sensing systems
is a crucial step in achieving an effective decision for occupant safety measures. This paper deals with the decision fusion
strategies of a multi-sensing embedded system to achieve significant enhancement in the reliability of occupant safety through
the fused decisions. Multi-sensing approaches to determine weight, vision, and crash sensing are developed for occupant detection,
classification, position calculation, and crash detection. A rule-based decision fusion algorithm is then developed to fuse
the multi-sensing decisions. The developed sensing systems are incorporated into an embedded device. To execute the embedded
system, a system interface between the software and hardware is developed using Lab Window/CVI with the C programming language.
The experimental results demonstrated that the real time operation of the embedded system validate the effectiveness of the
decision fusion algorithm, characterize the safety measures and monitor the decision application. Several events were tested
that prove the performance of the embedded system is robust towards occupant safety measures. |
