摘要： In a process for adjusting the angular position of the camshaft of a reciprocating internal combustion engine relative to the crankshaft, the crankshaft is connected to the camshaft by a 3-gear transmission having a driving shaft fixed to the crankshaft, a driven shaft fixed to the camshaft and an adjusting shaft driven by an electric motor. A crankshaft sensor signal is detected whose state changes when the angular position of the crankshaft changes. Moreover, an adjusting shaft sensor signal is detected whose state changes when the angular position of the adjusting shaft changes. Starting from an angular position reference value, a phase angle signal is tracked when the state of the crankshaft sensor signal and/or of the adjusting shaft sensor signal changes and adjusted to a predetermined set phase angle signal. The ignition of the internal combustion engine is then switched off and/or the rotational speed of the crankshaft is lowered below a predetermined minimum rotational speed. While the crankshaft and/or camshaft continues to rotate, the electric motor is powered in such a way that the camshaft is rotated up to a predetermined reference position relative to the crankshaft. The next time the internal combustion engine is started, the camshaft and crankshaft are positioned according to the reference position and this is detected by means of a sensor. The phase angle signal is adjusted to a reference value, then adjusted to the set phase angle signal.

摘要： The invention relates to a method for adjusting the position of the angle of rotation of the camshaft (3) of a reciprocating piston of an internal combustion engine in relation to the crankshaft (5). The crankshaft is drivingly connected to the camshaft (3) by means of an adjusting drive (1), which is embodied as a triple-shaft gear mechanism comprising a drive shaft which is fixed to the crankshaft, an output shaft fixed to the camshaft and an adjusting shaft. According to the invention, a phase angle signal (eACT) for the position of the angle of rotation of the camshaft in relation to the crankshaft is detected. A stop travel is carried out during which a stop element (6) connected to the drive shaft is moved towards a counter-stop element (7) that is connected to the camshaft, while the reaching of a stop position is monitored. A phase angle value relative to the stop (eSTOP) is determined when the stop position is detected. The phase angle signal relative to the stop is adjusted to a provided target angle phase signal (eSET). An adjacent or adjoining phase angle region is allocated to the phase angle value relative to the stop, and the phase angle signal is then compared with the phase angle region. In the event that the theoretical phase angle signal lies within the range of the phase angle region, the adjustment of the phase angle signal to the theoretical phase angle signal is interrupted in order to carry out another stop travel. To this end, the stop element is moved towards the counter-stop element, while the reaching of the stop position is monitored. When detecting the stop position the phase angle value relative to the stop is newly determined and subsequently the adjustment of the phase angle signal to the theoretical phase angle signal is continued.

摘要： In a method for determining a wear value of a transmission element arranged between a crankshaft and a camshaft of a reciprocating piston internal combustion engine, in particular a control chain or a toothed belt, the camshaft is driven by the transmission element by means of a drive part, for example a camshaft gearwheel. According to the invention, 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 at which the crankshaft drives the camshaft, and the wear value is determined from the difference between said measurement values.

摘要： The invention relates to a synchronization device for an engine, said device having a first active sensor and a second active sensor. The first active sensor is adapted to detect a first relative position of a first shaft and the second active sensor is adapted to detect the relative position of a second shaft. The first active sensor and the second active sensor are adapted to supply the control device with information on the nature of the relative position of the first shaft and of the second shaft or the relative position of the first shaft and the phase position between the first shaft and the second shaft. The control device is further adapted to supply a control signal for adjusting a definable phase difference between the first and the second shaft.
