摘要： In a method for operating a camshaft adjusting device, using an actuating drive, the actual setting of a camshaft with respect to the rotation of the crankshaft is followed corresponding to a setpoint setting ascertained in a control unit. In response to the occurrence of a lasting system deviation between the actual setting and the setpoint setting, an error signal is generated. The error signal is designed in multiple stages as a function of the system deviation, different weightings being imputed to the individual stages of the fault indication. By this measure, the fault indications of different weightings may be processed. Faults that are not serious, but nevertheless require attention, may be treated separately from serious faults.

摘要： A method and a device for operating an internal combustion engine, which make possible a defined and reliable cutting in or cutting off a gas-exchange valve of a cylinder. In at least one operating state, at least one intake valve or exhaust valve of a cylinder is cut off or at least one cut-off intake valve or exhaust valve of the cylinder is cut in again, the at least one intake valve or exhaust valve being opened and/or closed using an operating element; and the operating element being switched off or switched on again using a coupling element. A response delay time is ascertained which is required for the operation of the coupling element for the switching off or switching on again the operating element. Furthermore, a switching time window is ascertained within which the operation of the coupling element is desired. Moreover, it is checked whether the switching time window is greater than the response delay time. In this case, a beginning of the switching procedure for cutting off or cutting in again the at least one intake valve or exhaust valve is established in such a way that the response delay time lies completely within the switching time window.

摘要： A method and a device for operating an internal combustion engine having multiple cylinders allows for an operating state of the internal combustion engine to be switched over as quickly as possible following the receipt of a switchover request. For this purpose, at least one intake or exhaust valve of a cylinder is switched off or at least one switched-off intake or exhaust valve of the cylinder is switched on again in at least one operating state of the internal combustion engine in response to the switchover request. With the receipt of a switchover request, a delay time or a delay crank angle is ascertained which is required for switching off or switching on again the intake or exhaust valve of one of the cylinders. Starting from the time or crank angle of the receipt of the switchover request and taking into account the ascertained delay time or the ascertained delay crank angle, the cylinder is selected whose at least one exhaust valve following the expiration of the delay time or of the delay crank angle starting from the time or crank angle of the receipt of the switchover request is the next to open in the switched-on state or would be the next to open, though it is switched off. This cylinder is ascertained as the one whose at least one intake or exhaust valve is designated to be the first to be switched off or switched on again following the receipt of the switchover request.
