Abstract

Dispositivo di controllo (1) per una trasmissione (2) automatizzata di un veicolo industriale, comprendente una leva di selezione (9) a quattro posizioni (U, EU, D, ED) provvista di un pulsante (F), ed un'unità di controllo (10) atta a generare segnali di comando (12) per un gruppo valvolare (8) di un gruppo attuatore (6) del cambio (5); 1'unità di controllo (10), in corso di marcia, è atta a comandare l'innesto della prima o della seconda marcia superiore o inferiore a quella innestata in risposta a segnali di ingresso corrispondenti all'azionamento della leva (9) in una rispettiva delle quattro posizioni (U, EU, D, ED), nonché l'innesto della marcia più alta o più bassa compatibile con un campo di funzionamento normale del motore, oppure della marcia più bassa compatibile con l'integrità meccanica del motore e della trasmissione (2), in risposta a segnali corrispondenti all'azionamento combinato della leva (9) e del pulsante (F), o a partire da una condizione di neutro del cambio (5).
