Abstract

In una disposizione a comando elettronico per variare il rapporto di trasmissione di un cambio di velocità di un aggregato di azionamento di un autoveicolo, una variazione in senso di inserimento di una marcia superiore, che era impedita mediante un segnale di bloccaggio generato in funzione di parametri del controllo dell'aggregato di comando oppure dello stato di marcia, viene di nuovo riammessa, quando il pedale di marcia raggiunge di nuovo una posizione significante, determinata da una variazione di livello del segnale di bloccaggio e quando è passato il tempo di ritardo che stabilisce l'azionamento del pedale di marcia.
