Sensing Considerations and Kradeoffs for Single Point Sensing

Supplemental Inflatable Restraint (SIR) systems, or airbags, are becoming standard equipment on many passenger cars and light duty trucks and are, therefore, being applied in a wide range of vehicles in large volumes.

This paper reviews the basic differences between single point sensing and multi-point sensing systems. It then discusses sensing-related considerations relevant to the design of a single point sensing system.

This paper also discusses the importance of modeling and simulation in developing SIR sensing algorithms and evaluating their performance. The paper concludes by explaining why timely pole crash detection can be a passenger compartment sensing challenge.
