Abstract:
1. The method for adjusting a relative angle of rotation (Φ) between a camshaft ( 12 ) and a crankshaft ( 5 ) using an electromechanical phase adjuster ( 11 ), comprising the steps: calculating a deviation in the angle of rotation (ΔΦ) between a desired angle of rotation (Φ calculating a desired adjustment speed (Ω calculating a deviation of the adjustment speed (ΔΩ) between a desired adjustment speed (Ω calculating an output parameter dependent on the deviation of the adjustment speed (ΔΩ) through an adjustment speed adjuster ( adjusting the angle of rotation (Φ) as a function of the parameters calculated in the preceding steps using an electromechanical actuator (
