Abstract

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.
