  • End of valve motion detection for a spool control valve
    Patent number: 6848626
    Abstract: A fuel injector system (10) calculates a first derivative filtered signal and a second derivative filtered signal from an unpowered spool valve coil signal. When the spool valve (16) reaches the end of travel, either open or closed position, a flat slope f is generated on the falling edge of the bell shaped signal. The second derivative provides a readily apparent determination of when the steep slope occurs. A comparator (62) thereby need only determine when the second derivative is zero to identify that the spool valve has reached the end of travel.
