A method for detecting the reciprocal position between a cylinder and a piston in a cylinder-piston unit, including the following phases: setup of a cylinder-piston unit featuring at least one tubular body (2) presenting at least one passing accommodation host (6); at least one moving body (5) which can be longitudinally shifted in such tubular body (2), featuring at least one reference area (5c) extending for a portion (5d) on the surface of such moving body (5); at least means of detection (7) which can be accommodated in such passing accommodation host (6), oriented towards such moving body (5) and meant to detect the presence or absence of such reference area (5c) at one of their detection area (7c), and to generate at least one corresponding output electrical signal (s7), as a response to the possible detection of such reference area (5c); at least one elaboration and program control unit (8), meant to receive as an input at least one of such output electrical signals (s7) and to generate as an output at least one electrical signal (s8) of detection; activation of such detection means (7) (phase 100); elaboration by at least one of such elaboration and program control units (8) of at least one of such signals (s7) which are the output of such detection means (7) (phase 200), with such elaboration phase including a comparison (phase 220) between at least one of such output electrical signals (s7) and the respective maximum and minimum reference thresholds (Smax, Smin); generation, based on such elaboration (phase 200), of a electrical signal of detection (s8) by at least one of such elaboration and program control units (8) (phase 300); such maximum and minimum reference thresholds (Smax, Smin) being periodically updated. |
