In order to control electromechanically activated charge cycle valves, a circuit is provided in which placement control elements actuate an output stage for the electromechanically activated charge cycle valves and control a gentle placement of the charge cycle valves in a respective end position. For the purpose of communication with the operational control unit of the internal combustion engine, a digital communications computer is provided which provides the placement control element with timing signals. As a result, the placement control elements are freed of communications functions and can be dedicated to performing the placement control in real time.

Circuit for controlling at least one electromechanically activated inlet valve and at least one electromechanically activated outlet valve of an internal combustion engine
