Preferably, the force F or the force Fis force Fs containing a component in a shear direction. Preferably, in the first step, the measured values Vf in a specific interval Zfrom time Tto Tafter the impact are obtained chronologically. Preferably, the evaluation is made based on a difference between a maximum value and a minimum value of the measured values Vf.
