Abstract

In un procedimento per la compensazione dell'errore dell'angolo di sterzatura per uno sterzo totalmente idraulico, in cui all'escursione di un volante (5) sono rilevati un angolo del volante ed un angolo del motore (8) dello sterzo come pure la velocità del volante ed il flusso di fluido tra un dispositivo di comando (4) dello sterzo ed il motore dello sterzo (8) è variabile in funzione dell'errore dell'angolo di sterzatura, si intende aumentare la comodità di guida malgrado la compensazione dell'errore dell'angolo di sterzatura.A tale scopo, nel procedimento la compensazione ha luogo ad ogni velocità del volante e ad ogni errore dell'angolo di sterzatura e la variazione del flusso di fluido avviene in funzione della velocità del volante e dell'errore dell'angolo di sterzatura. Nello sterzo totalmente idraulico è previsto un moltiplicatore (24) che moltiplica le uscite di un formatore di differenze e di un differenziatore tra di loro, mentre l'uscita del moltiplicatore è applicata attraverso un componente di proporzionalità (25) con un dispositivo di comando valvolare (26) collegato ai fini dei segnali con un dispositivo valvolare.
