Abstract

Method and device for controlling an inductive load by pulse width modulation, on the basis of a periodic set point control signal having a given set point duty cycle. The set point control signal is, in each period of the set point control signal, in a first logic state determined from the high and low logic states for at least a first duration, and is in the other logic state during the rest of the period. Control signals are generated for activating the inductive load, on the basis of the set point control signal. With the aid of a first counter, the first duration (t0) is determined on the basis of the set point control signal. Via a second counter, a second duration (t0−td2) is determined, for which a logic signal corresponding to an effective control signal observed in the load is in the first determined logic state.
