摘要： A method and control system are disclosed for controlling an internal combustion engine having fuel injector(s), a camshaft for actuating inlet and/or outlet valve(s), a valve-train adjusting device for controllable switchover between different valve actuating characteristics, and optionally a camshaft sensor which supplies a camshaft signal representing the camshaft angle, a crankshaft sensor which supplies a crankshaft signal representing the crankshaft angle, and a control unit which controls the fuel injectors to inject predetermined fuel quantities at predetermined injection instants, wherein these stipulations take place as a function of the switching state of the valve-train adjusting device. To obtain information about this switching state, cylinder pressure signal(s) supplied by a cylinder pressure sensor are evaluated with regard to interference signals, and the evaluation result is used in determining the switching state of the valve-train adjusting device for stipulating the fuel quantities to be injected and/or the injection instants.
