Abstract
The invention relates to a method and device for determining a phase position between a crankshaft and a camshaft of an internal combustion engine. An internal combustion engine is provided with a crankshaft, a camshaft, at least one cylinder and an intake tract to which gas inlet valves are assigned that control the gas supply from the intake tract to the one or more cylinders and that are driven via the camshaft. The intake tract is associated with a pressure sensor that detects an intake tube pressure in a manifold of the intake tract. The phase position is determined depending on the intake tube pressure detected. The inventive method and device allows to determine the phase position in a simple manner and without any additional sensor system.
