Abstract (en)

[origin: WO2012007323A1] The invention relates to the control of an internal combustion engine (10) having at least one fuel injector (14) per cylinder (12), at least one camshaft (20) for actuating at least one inlet valve (16) and/or at least one outlet valve (18), wherein a valve-train adjusting device (21) is provided for the controllable switchover between different valve actuating characteristics, optionally having a camshaft sensor (26) which supplies a camshaft signal (CAM) which is dependent on the camshaft angle, a crankshaft sensor (28) which supplies a crankshaft signal (CRK) which represents the crankshaft angle (CRA), and a control unit (24) which controls the fuel injectors (14) in such a way that they 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 (21). In order to obtain information about this switching state, at least one cylinder pressure signal (P) which is supplied by a cylinder pressure sensor (32) for measuring the pressure in an associated cylinder (12) is evaluated with regard to interference signals (S1, S2), and the evaluation result is taken into consideration in a determination of the switching state of the valve-train adjusting device (21) for stipulating the fuel quantities to be injected and/or the injection instants.
