Method and device for ascertaining a position of a camshaft and a phase of an internal combustion engine

A method for ascertaining a position of a camshaft and a phase of an internal combustion engine, the method comprising:

• assigning a camshaft position to a position of a tooth flank of a first position sensor wheel;
• and
• assigning a phase of the internal combustion engine to a position of a tooth flank of a second position sensor wheel;
• wherein the first position sensor wheel and the second position sensor wheel are in a device for ascertaining the position of the camshaft and the phase of an internal combustion engine, including:
• the first position sensor wheel, which has multiple teeth on its circumference and is connected in a rotatably fixed manner to a camshaft of the internal combustion engine including multiple cylinders;
• a first position sensor to detect a position of a tooth flank of the first position sensor wheel;
• a transmission, which connects the camshaft to a crankshaft of the internal combustion engine;
• the second position sensor wheel, which has at least one tooth on its circumference, and which is connected to the transmission so that it is driven in synchronization with the camshaft;
• and
• a second position sensor to detect a position of a tooth flank of the second position sensor wheel.

A computer readable medium having a computer program, which is executable by a processor, comprising:

• a program code arrangement having program code for ascertaining a position of a camshaft and a phase of an internal combustion engine, by performing the following:
• assigning a camshaft position to a position of a tooth flank of a first position sensor wheel;
• and
• assigning a phase of the internal combustion engine to a position of a tooth flank of a second position sensor wheel;
• wherein the first position sensor wheel and the second position sensor wheel are in a device for ascertaining the position of the camshaft and the phase of an internal combustion engine, including:
• the first position sensor wheel, which has multiple teeth on its circumference and is connected in a rotatably fixed manner to a camshaft of the internal combustion engine including multiple cylinders;
• a first position sensor to detect a position of a tooth flank of the first position sensor wheel;
• a transmission, which connects the camshaft to a crankshaft of the internal combustion engine;
• the second position sensor wheel, which has at least one tooth on its circumference, and which is connected to the transmission so that it is driven in synchronization with the camshaft;
• and
• a second position sensor to detect a position of a tooth flank of the second position sensor wheel.
