Abstract (en)
[origin: WO2006050790A1] The invention relates to a method for calibration of a positional sensor on a rotational actuator device for control of a gas exchange valve in an internal combustion engine. The rotational actuator device comprises a controlled electric motor with an operating element for operating the gas exchange valve, two energy storage means acting in opposing drive directions on the gas exchange valve, a control and regulation device, controlling the electric motor with regard to the rotor angle thereof relative to a stored set path, and a positional sensor for determining the rotor position. According to the invention, at least one status parameter for the electric motor is determined, the at least one status parameter compared with a reference parameter and, on a difference between the parameters for comparison, the stored set path and/or the recorded positional sensor signal are altered depending on the status parameter.
