Abstract:
1. A method for determining an angular position signal (φ i ) representing a rotary motion of a rotating part of an internal-combustion engine with a speed sensor ( 11 ) that outputs a rotation-measurement signal (φ mess,i , t mess,i ) representing the rotary motion of a sensing wheel connected to the rotating part, and at least one pressure sensor ( 12 ) that outputs a pressure signal (P Lz,i ) representing a pressure in a combustion chamber, having the following steps: detecting the pressure signal (P detecting the rotation-measurement signal (φ calculating a correction quantity (Δφ determining the angular position signal (φ determining a first energy value ({tilde over (E)} determining a second energy value ({tilde over (E)} calculating the correction quantity (Δφ
