Camshaft position pulse-generating wheel and method and device for ascertaining a camshaft position

A method for determining a position of a camshaft using a device or ascertaining a position of a camshaft, the method comprising:

• assigning, per revolution of the camshaft and per cylinder of the internal combustion engine, a camshaft position to a position of a negative tooth edge of a camshaft position pulse-generating wheel;
• wherein the device for ascertaining a position of a camshaft, includes:
• the camshaft position pulse-generating wheel having a plurality of teeth on a circumference at irregular angular distances, wherein it has a tooth edge in each case, at least at 0°, 90°, 120°, 180°, 240° and 270° of the circumference, which is connected to a camshaft of a four-stroke internal combustion engine having at least one cylinder in a torsionally fixed manner;
• and
• a camshaft position sensor to detect a position of a tooth edge of the camshaft position pulse-generating wheel.

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

• a program code arrangement having program code for determining a position of a camshaft using a device or ascertaining a position of a camshaft, by performing the following:
• assigning, per revolution of the camshaft and per cylinder of the internal combustion engine, a camshaft position to a position of a negative tooth edge of a camshaft position pulse-generating wheel;
• wherein the device for ascertaining a position of a camshaft, includes:
• the camshaft position pulse-generating wheel having a plurality of teeth on a circumference at irregular angular distances, wherein it has a tooth edge in each case, at least at 0°, 90°, 120°, 180°, 240° and 270° of the circumference, which is connected to a camshaft of a four-stroke internal combustion engine having at least one cylinder in a torsionally fixed manner;
• and
• a camshaft position sensor to detect a position of a tooth edge of the camshaft position pulse-generating wheel.
