METHOD AND DEVICE FOR START CONTROL OF OCCUPANT CRASH PROTECTION DEVICE AND RECORDING MEDIUM WITH START CONTROL PROGRAM FOR OCCUPANT CRASH PROTECTION DEVICE RECORDED ON IT

摘要

PROBLEM TO BE SOLVED: To prevent the misjudgement of impact application generated by a phenomenon other than a car collision as signified originally, for example originating from a so-called under-the-floor interference, seat slide, etc. SOLUTION: In case an acceleration G exceeding the specified value GTH is sensed (Step 124) within a certain period after a speed integral value ΔV over a specified value was sensed (Step 112), Judgement is passed that it is due to an under-the-floor interference or seat slide, and the starting of a side air bag device is interrupted (Step 126). In case on the other hand, acceleration G exceeding the specified value GTH is not sensed (Step 124) within a certain period after a speed integral value ΔV over the specified value was sensed (Step 112), judgement is passed that it is a genuine collision, and the side air bag device is started (Step 120).
