1. A method for detecting a direction of a collision of a vehicle, the method comprising the following steps:
comparing a first acceleration signal to a first threshold value and to a second threshold value, to determine a first collision direction signal indicating a direction of the collision, the first acceleration signal representing a longitudinal acceleration of the vehicle, and the first threshold value and the second threshold value having different algebraic signs to be able to distinguish between two opposite directions of the collision;
comparing a second acceleration signal to a further threshold value, to determine a further collision direction signal indicating the direction of the collision; the second acceleration signal representing an acceleration of the vehicle subjected to smoothing; and
determining a result signal, using the first collision direction signal and the further collision direction signal, the result signal indicating the direction indicated by the first collision direction signal and by the further collision direction signal as an actual collision direction, when the direction of the collision of the first collision direction signal and the direction of the collision of the further collision direction signal match.
