摘要

In order to process a motor signal (I_a, U_m) of a DC motor (4), in particular of an adjustment drive of a motor vehicle, the armature current (I_a) and the motor voltage (U_m) of the DC motor (4) are detected and used for determining the back-emf (E) of the DC motor (4), wherein the determined back-emf (E) is used to generate a useful signal (S_f, S_EFL), which is in particular speed-proportional, from the armature current signal (I_a) for position sensing or for evaluating an excess force limitation.
