摘要： A method for determining a wear value of a transmission element between a crankshaft and a camshaft of a reciprocating piston internal combustion engine, in particular a timing chain or toothed belt, is provided. The camshaft is driven by the transmission element via a drive part, for example a camshaft gearwheel. In each case, at least one measurement value for the phase position of the drive part relative to the crankshaft is determined at time intervals during which the crankshaft drives the camshaft, and the wear value is determined from the difference between the measurement values.

摘要： A method for adjusting the rotational angle position of the camshaft (3) of a reciprocating piston internal combustion engine relative to the crankshaft (5) is provided. The crankshaft (5) is drivingly connected to the camshaft (3) via an adjusting drive (1), which is embodied as a triple-shaft gear mechanism, having a crankshaft-fixed drive shaft, a camshaft-fixed output shaft, and an adjustment shaft drivingly connected to an electric motor (4). A stop element is connected to the drive shaft and a counter-stop element is connected to the camshaft (3). The crankshaft rotational angle measuring signal and a position signal for the rotational angle of the adjusting shaft are detected during the starting step of the internal combustion engine. A phase angle signal for the position of the rotational angle of the camshaft (3), based on the initial position, in relation to the camshaft (3) is determined with the aid of the angle measuring signal, the position measuring signal and a gear variable of the triple shaft gear. After immobilization of the crankshaft (5) and the camshaft (3) in a reference position in relation to each other and after detection of the reference position, the phase angle in relation to the reference position is measured and is controlled to a target value signal.

摘要： In a method for adjusting the rotation angle position of the camshaft of a reciprocating-piston engine in relation to the crankshaft in which the crankshaft is in drive connection with the camshaft via an actuating gear, which is designed as a three-shaft gear having a drive shaft in a fixed mounting on the crankshaft, an output shaft in a fixed mounting on the camshaft and an actuating shaft which is in drive connection with an actuating motor, a measured value for the crankshaft rotation angle is determined for at least one crankshaft measurement point in time. For at least two actuating shaft measurement points in time, a measured value for the actuating shaft rotation angle is determined digitally. For at least one reference point in time which is after the crankshaft measurement point in time and the actuating shaft measurement point in time, an estimate for the rotation angle of the actuating shaft at the reference point in time is extrapolated from at least two actuating shaft rotation angle measured values, the time difference between the actuating shaft measurement points in time and the time interval between the latest actuating shaft measurement point in time and the reference point in time. A value for the rotation angle position is determined on the basis of the estimate, the at least one crankshaft rotation angle measured value and the transmission characteristic.

摘要： A method for adjusting a camshaft of an internal combustion engine during a stop phase and during a subsequent new startup phase of the internal combustion engine. Such methods are used, in particular, in so-called start-stop designs for combustion engines. The camshaft controls intake valves and/or exhaust valves of the internal combustion engine and is adjustable by a camshaft adjuster. By a desired startup position of the camshaft adjuster, control time points of the intake valves and/or the exhaust valves are defined in which mechanical work necessary for starting the internal combustion engine is reduced and/or pollutant emissions of the internal combustion engine are reduced. In the method according to the invention it is provided that the camshaft adjuster is set in a desired stop position during the stop phase. During a first section of the startup phase, the camshaft adjuster is set from the desired stop position into the desired startup position. During a second section of the startup phase, a setting of the camshaft adjuster is performed as a function of measured operating parameters of the internal combustion engine. Furthermore, the invention relates to an internal combustion engine with a camshaft that can be adjusted by a camshaft adjuster.

摘要： An adjusting device for the rotational position of the camshaft of a reciprocating piston engine relative to the crankshaft, has an actuator for adjusting the rotational position that is connected into a control circuit. The control circuit has a controller, which is linked to a data memory, in which controller coefficients for a transfer function of the controller are stored. The data memory has at least two memory areas in which various sets of controller coefficients are stored. The control circuit is connectable with the aid of a mode selector, optionally or alternately, in such a way to one of the data memory areas that the controller coefficient set stored in the particular data memory area is used for the control. A device for ascertaining the operating state of the adjusting device and/or of the reciprocating piston engine is connected to the mode selector in such a way that the controller coefficient set used in the particular case for the control is dependent on the operating state.
