Vehicle crash sensor has hollow body in bumper with pressure sensors to detect waves generated by impacts

摘要

A vehicle crash sensor has a hollow body (1) in the bumper (13) with pressure sensors (2, 3) measuring pressure waves generated by an impact with an obstruction (11) or multiple impacts within a time window. Slow pressure changes are compensated by a pressure equalizer (6). Includes Independent claims for cars fitted with the sensor system.
