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.
