Method and device for detecting a collision and delimiting it with respect to normal vehicle operation

A method for detecting a collision of a vehicle, using a measuring device rigidly connected to the vehicle, including the following features: -in each instance, an acceleration of the measuring device with regard to a plurality of device coordinate axes specific to the measuring device is measured; in each instance, an installation position angle of the measuring device with respect to a plurality of vehicle coordinate axes specific to the vehicle is calculated and/or measured and/or programmed from outside; with the aid of the installation position angles, a vehicle acceleration along the vehicle coordinate axes is ascertained, and an evaluation of the accelerations is undertaken; and the degree of determination of the installation position is ascertained by the device and taken into consideration for weighting the accelerations. the collision is detected in light of the evaluation of the vehicle acceleration.
