FIELD: internal combustion engines.
SUBSTANCE: group of inventions discloses various embodiments relating to detection of an end-stop position of a waste gate valve in the turbine of a turbocharger and calibration of a waste gate position sensor relative to the detected end-stop position. Methods for calibrating a waste gate position sensor are disclosed. Method for calibrating a waste gate position sensor comprises adjusting a waste gate valve to a first end-stop position and associating a first feedback position with the first end-stop position; adjusting the waste gate valve to a second end-stop position and associating a second feedback position with the second end-stop position. Further, method comprises adjusting a position sensor gain based on the first feedback position and the second feedback position.
EFFECT: technical result is improved accuracy of waste gate control.
