Multi-axis acceleration sensors

  • 01-Nov-2011 01:29 EDT

Remote acceleration sensors from TRW Automotive Holdings offer improved crash-sensing performance by detecting impacts from more than one direction simultaneously. Unlike traditional accelerometers used in crash sensing that measure acceleration data in one dimension, multi-axis sensors add additional single-axis sensors in the same housing or use multi-axis sensors to measure acceleration in more than one dimension simultaneously. According to TRW, this can significantly improve crash sensing performance in newly required Federal Motor Vehicle Safety Standard (FMVSS) 214 regulatory oblique side-pole impact and upcoming/proposed New Car Assessment Program (NCAP) and Insurance Institute for Highway Safety (IIHS) rating tests such as the front small-overlap impacts and front-pole impact.
