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

A circuit for controlling valves, including at least one electromechanically activated inlet valve and at least one electromechanically activated outlet valve, of a cylinder of an internal combustion engine, the circuit comprising:

• at least one placement control element having a plurality of output stages connected to electromagnets of the valves, at least one of said output stages connected to each of said electromagnets of the valves, said placement control element receiving timing signals and valve position signals, said placement control element actuating said output stages in dependence on the timing signals and, while processing the valve position signals for indicating a position of the valves, said placement control element regulates an energization of the electromagnets to bring about a gentle, low-noise placement of each of the valves to an end position;
• a digitally operating communications computer for evaluating a crankshaft position signal and connected to said placement control element;
• and
• a communications connection for connecting said communications computer to an operational control unit of the internal combustion engine, said communications computer exchanging data over said communications connection to the operational control unit and generates the timing signals received by said placement control element in dependence on the crankshaft position signal and of the data received from the operational control unit.
