A method for limiting peak currents, particularly depending on a charge quantity provided by a voltage source, and the maximum pitch of the current flanks of an electric motor for an electrohydraulic motor vehicle brake system, particularly a pump motor, controlled by pulse width modulation, wherein a change to an actual duty cycle of the PWM is made by a first duty cycle of the PWM on a second duty cycle at runtime, wherein the change takes place according to a positive or negative pitch value calculated and/or changeable at runtime. The invention further describes an electronic circuit arrangement for the implementation of a method for limiting peak currents and the maximum pitch of current flanks.
