Abstract

A method for crash type identification for a vehicle in which sensor data from the left vehicle side and from the right vehicle side are recorded and analyzed via at least two sensor units, as well as an associated device for crash type identification for a vehicle. The sensor data, recorded after an impact, are gated, at least one first gating of the recorded sensor data being checked for fulfillment of a stability criterion and, after meeting the stability criterion, at least one second gating of the recorded sensor data is compared with a predefined threshold value, a first criterion for an asymmetrical impact flag signal being recognized when the second gating of the recorded sensor data exceeds the predefined threshold value and/or falls short of the predefined threshold value.
