Method and apparatus for distinguishing of different crash situations for the control of a restraint system of a vehicle

摘要

A method of discriminating different crash situations for the control of a restraint system of a vehicle with at least one control device (1) for the restraint system, wherein said control means (1) at least one acceleration signal (2) supplies, characterized by the following process steps:(S1) start of a time window in the case of detection of a crash start;(S2) the first and second analyzing of the acceleration signal (2) in this time window;(S3) be taken into account of values of the first analyzing of the acceleration signal (2) for influencing of the second analyzing of the acceleration signal (2) and storing values of the second analyzing of the acceleration signal (2);(S4) storing predetermined time-dependent first threshold values (4) in this time window;(S5) the end of the time window according to a predetermined criterion; and(S6) differ from different crash situations, by comparing the stored values of the second analyzing with at least one of the stored first threshold values (4) in accordance with the time of the time window end.
