Abstract

Un sistema elettronico di comando di un cambio automatico continuo (2) per autoveicoli comprende pulsanti (10, 12, 14) per la selezione rispettivamente della marcia avanti con le marce basse o con tutte le marce e della retromarcia. La retromarcia, può' essere, inserita solo se la velocità dell'autoveicolo è inferiore ad una soglia prefissata; il cambio si porta automaticamente nella posizione di parcheggio se il commutatore di accensione (20) è nella posizione aperta e la velocità dell'autoveicolo è inferiore ad una soglia prefissata.(Figura unica).
