DEVELOPMENT AND EVALUATION OF AUTOMOBILE CRASH SENSORS
Reported herein are the results of a research effort devoted to the investigation of post-contact crash sensing techniques. The effort consisted of an extensive survey of existing crash sensor technology, experimental testing of crash sensing devices and analysis of results. The survey effort involved a literature search and study of all pertinent reports and papers published on the subject of automobile crash sensing. In addition, personal contact was made with the various manufacturers of crash sensing devices to elicit additional sensor information to the extent possible. Testing included full-scale crash tests of unmodified vehicles instrumented with crash sensors and accelerometers. Laboratory bench testing of crash sensors was conducted employing a centrifuge device to determine static bias levels and a Linear Accelerator apparatus to provide dynamic performance information. Accelerator testing was conducted at 200 degrees F. and -50 degrees F., in addition to room temperature (70 degrees F.), to ascertain temperature effects on sensor functioning. Parameters investigated included time-to-fire, acceleration level at fire and sensor velocity change experienced at fire. In addition to the experimental investigation of existing state-of-the-art crash sensing devices, effort was devoted to the development of an induction coil crash device which actuates a squib power circuit when the the relative velocity between the vehicle and its front bumper exceeds a pre-selected threshold. /Author/
