Investigation And Judgment For SRS Quality Problems Of HFSAIMA

At present the aerocyst dispute with difficulty solves is a big difficulty, how the collision degree determined that, this affects directly was recognizing whether the aerocyst does have the quality problem."Belongs to frontage collision accident regarding the confirmation, most is difficult in the lawsuit to process is the collision degree determination", some accidents from the accident scene, the accident vehicle distortion shape on very easy to judge the accident pattern, if does not belong to frontage collision, then the aerocyst not protective function; But if in front of the vehicles the carline structure obvious distortion the aerocyst accident has not exploded, very easy to determine belongs explodes by mistake; If in front of the vehicles the carline has had the flexure distortion, after the power unit obvious moves, uses the equivalent fixed wall which this vehicle the energy grid data and the automobile body residual deformeter figures out to bond the collision vehicle speed also by far to be higher than the factory hypothesis the threshold value speech, the aerocyst should blow out, before but whether belongs to the quality question to still need to gain the accident to have the aerocyst working condition material.This article thought increases accident data-carrier storage (EDR) in security aerocyst ECU, the recording collision accident first 5 second driving data as well as the security aerocyst fires the latter 300 milliseconds data, these data including vehicle speed, whether was before the safety belt as well as the collision the security aerocyst newspaper warning light whether has shone and so on the parameters, after had the collision accident, through the collision data read readout, took the security aerocyst whether should one of detonation important determination bases. Key word security aerocyst dispute frontage collision accident data...
