Abstract
Vengono indicati procedimenti per esercire apparecchi di comando con correzione automatica dopo l'esclusione dell'accensione di un motore endotermico, i quali salvaguardano per quanto possibile la batteria. Allo scopo possono essere adottati singolarmente oppure in combinazioni arbitrarie, di preferenza tutti insieme, tre principi e cioè:- funzioni soggette a correzione automatica non vengono più eseguite, come d'abitudine, fino a che si è raggiunto un prestabilito intervallo fisso di tempo, bensì le funzioni vengono o interrotte quando valori di particolari grandezze raggiungono un valore di soglia preassegnato in modo fisso, oppure raggiungono un valore di soglia fissato in funzione di grandezze di esercizio prima della disinserzione del motore endotermico. La grandezza fisica di volta in volta sorvegliata ed il valore di soglia a lei associato sono rispettivamente selezionati in maniera tale che, quando il valore attuale ha raggiunto il valore di soglia e conseguentemente la funzione soggetta a correzione automatica viene interrotta oppure addirittura non viene punto avviata, ciò abbia lungo senza sostanziale pregiudicamento della capacità di nuovo avviamento del motore endotermico.- funzioni soggette a correzione automatica, specialmente quelle che richiedono un elevato flusso di corrente, non vengono eseguite contemporaneamente; bensì l'una dopo l'altra.- Viene sorvegliata la capacità della batteria di fornire corrente e non appena è rilevabile che questa appena è ancora sufficiente per avviare il motore endotermico raffreddato, le funzioni soggette a correzione automatica vengono interrotte oppure addirittura non vengono punto iniziate.(Figura 1).
