Abstract

Il sistema comprende un attuatore (H) con un organo mobile (4) atto a provocare la sterzatura delle ruote posteriori del veicolo, e dispositivi di controllo (C) dello spostamento di detto organo mobile (4). I dispositivi di controllo comprendono due stadi di pilotaggio (14A, 14B) controllati da due processori indipendenti (A, B) ed atti a determinare, congiuntamente. o separatamente, l'attivazione controllata dell'attuatore (H) in funzione delle caratteristiche di rispettivi segnali di controllo. Un'elettrovalvola di sicurezza (15-20) provoca lo spostamento ed il mantenimento di detto organo mobile (4) in una posizione neutra prefissata, a cui corrisponde una sterzatura nulla di detto ruote, quando viene meno un segnale di abilitazione ad un ingresso (18) di abilitazione generato da detti processori (A, B).(Figura 1).
