Abstract: A device for ascertaining a camshaft position and a phase of an internal-combustion engine having multiple cylinders, including a first position sensor wheel having multiple teeth on its circumference and rotatably and fixedly connected to an engine camshaft; a first position sensor for detecting a tooth flank position of the first wheel; a transmission connecting the camshaft to a crankshaft; a second position sensor wheel having at least one tooth on its circumference and being connected to the transmission so that it is synchronously driven with the camshaft, and a second position sensor for detecting a tooth flank position of the second wheel. For ascertaining a camshaft position and a phase of an engine with this device, a camshaft position is assigned to a position of a tooth flank of the first wheel and a phase of the engine is assigned to a tooth flank position of the second wheel.

Abstract: A camshaft position pulse-generating wheel having a plurality of teeth on its circumference at irregular angular distances and one tooth edge in each case, at least at 0°, 90°, 120°, 180°, 240° and 270° of its circumference, and a device for ascertaining a camshaft position. In this position, the camshaft position pulse-generating wheel is connected, in a torsionally fixed manner, to a camshaft of a four-stroke internal combustion engine having at least one cylinder and a camshaft position sensor to detect a position of a tooth edge of the camshaft position pulse-generating wheel. For determining the camshaft position, per revolution of the camshaft and per cylinder of the internal combustion engine, either exclusively a camshaft position is assigned to a position of a negative tooth edge of the camshaft position pulse-generating wheel or to a position of a positive or a negative tooth edge of the camshaft position pulse-generating wheel.
