  • Control method and system for a fluid control device, based on position sensor learning
    Patent number: 8190297
    Abstract: A control method is provided for a fluid control device, particularly for an internal combustion engine, equipped with a position sensor having a nominal characteristic curve representative of a predetermined relationship between an admissible range of position values and a corresponding range of return electric signal values. The method includes, but is not limited to determining an offset (offsetopen; offsetclose) between a returned signal related to at least one defined position of the device and an expected signal related to the defined position of the device according to the nominal characteristic curve, estimating an updated characteristic curve of the sensor by applying the offset (offsetopen; offsetclose) to the nominal characteristic curve, and applying a predetermined control strategy of the fluid control device according to the updated characteristic curve.
