Abstract

Un procedimento per regolare la forza frenante in un impianto di frenatura antibloccaggio per veicoli prevede che si misuri in modo noto lo slittamento e/o la decelerazione dei giri di una ruota frenata e si confrontino di volta in volta con un valore di soglia prestabilito per abbassare la forza frenante al superamento del valore di soglia. Onde evitare abbassamenti di pressione non voluti, si aumenta per intervalli di tempo prestabiliti il valore di soglia rispetto ad un valore base (SG ) e quindi lo si riduce nuovamente. Nel momento T1, in cui la decelerazione dei giri della ruota frenata è maggiore del valore corrispondente alla decelerazione massima fisicamente possibile del veicolo, si aumenta bruscamente il valore di soglia e poi lo si riduce secondo una funzione prestabilita. Durante l'abbassamento del valore di soglia si misura la variazione di velocità della ruota frenata per intervalli di tempo prestabiliti (SIMBOLO) T e si confronta con l'aumento momentaneo del valore di soglia e poi, se da questo confronto risulta che detta variazione di velocità è maggiore dell'aumento momentaneo del valore di soglia, si abbassa il valore di soglia fino al valore base (SG).
