A method for detecting a direction of a collision of a vehicle. The method includes a comparing step, in which a first acceleration signal is compared to two threshold values, in order to determine a first collision direction signal indicating a direction of the collision, and in which a second acceleration signal is compared to a further threshold value, in order to determine a further collision direction signal indicating a direction of the collision. The second acceleration signal represents the acceleration of the vehicle subjected to smoothing. In the determining step, using the first collision direction signal and the further collision direction signal, a result signal is determined, which indicates the direction indicated by the first collision direction signal and by the further collision direction signal as an actual collision direction.

A method for detecting a damage to a vehicle. The method includes a reading-in step and an evaluation step. In the reading-in step, a body sensor signal is read in via an interface to a body sensor of the vehicle, the body sensor signal representing at least one body vibration recorded in the body area. A chassis sensor signal is furthermore read in via an interface to a chassis sensor of the vehicle, which represents at least one chassis vibration recorded in the chassis area. In the evaluation step, the body sensor signal and the chassis sensor signal are evaluated to obtain an evaluation result representing the damage.
