摘要： In a method and a device for operating an internal combustion engine, a first variable characterizing the air-mass flow to the internal combustion engine is determined, and a second variable characterizing the air-mass flow is determined. The second variable characterizing the air-mass flow is used to derive a third variable characterizing the air-mass flow, which is delayed in time with respect to the second variable characterizing the air-mass flow. A difference is formed between the second variable characterizing the air-mass flow and the third variable characterizing the air-mass flow. The first variable characterizing the air-mass flow is corrected by the difference.

摘要： A method and a device for monitoring the intake manifold pressure of an internal combustion engine in which a measured signal for the intake manifold pressure is compared with a reference signal for the intake manifold pressure. For a deviation of the measured signal for the intake manifold pressure from the reference signal for the intake manifold pressure, a tolerance range is predefined for error-free operation of the intake and/or exhaust valves of at least one cylinder of the internal combustion engine. A check is made whether the measured signal for the intake manifold pressure deviates from the reference signal for the intake manifold pressure by more than a predefined tolerance range. In this case an erroneous operation of the intake and/or exhaust valves is detected; otherwise an error-free operation of the intake and/or exhaust valves is detected.

摘要： A method for regulating an actual variable (X) to a setpoint variable (W), a manipulated variable (Y) being ascertained from the setpoint variable (W) and the actual variable (X), and the manipulated variable being supplied to an input of a controlled system, and a change in the actual variable (X) occurring only upon the manipulated variable being changed by a minimum amount, an intermediary manipulated variable (Y′), to which a correcting quantity (K) is applied in the steady-state condition of the regulation for forming the manipulated variable (Y), being first ascertained from the setpoint variable (W) and the actual variable (X), only values which change the manipulated variable (Y) by less than a minimum amount being allowed for the correcting quantity (K).
