Verfahren zum Erfassen einer Kollision mittels dreier gerichteter Beschleunigungssignale und Vorrichtung zur Ausführung des Verfahrens

摘要

An apparatus and method for judging an oblique, center pole and front barrier collision with the acceleration signals (Ax,Ay,Az) of a vehicle in back-and-forth (X), left-and-right (Y) and up-and-down (Z) directions are disclosed. The acceleration signal detected by an acceleration sensor is filtered (20) and transferred to a collision judging part (30). The collision judging part (30) judges a dangerous collision and generates a reset signal. The acceleration signal detected by the acceleration sensor is integrated (40). The judgement for an oblique, center pole and front barrier collision is achieved by comparing the integrated acceleration signal with each preset value. Both the low speed front barrier collision and the high speed center pole collision can be easily judged by detecting three directional accelerations of a vehicle and comparing those accelerations with the predetermined reference values.
