Abstract

Procedimento e sistema per il controllo elettronico di un sollevatore idraulico associato ad una trattrice agricola e recante un attrezzo, comprendente le fasi di rilevare un parametro operativo, generare segnali elettrici indicativi del parametro operativo rilevato, e controllare il sollevatore tramite detti segnali elettrici in cui detto parametro operativo consiste nello sforzo dell'attrezzo, o nella sua posizione, o nello slittamento della trattrice, eventualmente combinato con lo sforzo dell'attrezzo, caratterizzato dal fatto che consiste nel selezionare uno di detti parametri operativi come parametro di controllo principale, e nel selezionare almeno uno degli altri di detti parametri operativi come parametro di controllo secondario atto a subentrare al parametro di controllo principale qualora il valore rilevato del parametro secondario superi un valore di soglia prefissato.(Figura 1)
