Several side-impact sensing technologies have been introduced into the market during the last decade. Acceleration sensing system and pressure sensing systems are two state of the art applications today. Presently, compliance with new crash performance regulations and vehicle manufacturer specifications requires additional and enhanced side impact sensing capabilities. An existing solution to these demands is a multi-point sensing system, with centralized signal evaluation, that utilizes all available crash sensor information. In particular, this solution employs an optimal combination of sensors designed to measure different physical characteristics of an impact event. Pressure-based side impact sensing system units are described in this paper as well as acceleration-based side impact sensing system units. The combination of acceleration- and pressure-based sensing systems is described. By combining the features of deformation measurement of soft cavities by dynamic air-pressure sensors with traditional acceleration measurement of structures, a system can be created with excellent crash performance and robustness in the field. Combining the information from these two physically different signals provides a robust and predictable decision, discriminating 'must deploy' and 'no deploy' events. The combination also provides a much higher immunity against typical vehicle misuse and abuse events. The resulting system provides excellent crash performance and robustness in the field.
