Abstract

In un procedimento per la determinazione della velocità di marcia effettiva, in particolare su veicoli su rotaie, sulla base di valori costantemente calcolati delle velocità, da una combinazione ruota polare/trasmettitore di impulsi vengono prodotti e rilevati segnali di velocità proporzionali alla frequenza e attraverso un microprocessore viene calcolato una velocità di marcia simulata. Per poter effettuare anche nel caso di coefficienti di aderenza differenti e tratti di percorso una ottimizzazione della frenatura, viene proposto che partendo da una pressione (P) misurata in un cilindro di frenatura (4) e da un segnale elettrico di pressione (I), corrispondente a questa, e al verificarsi di una decelerazione critica di un asse di ruote (7) viene determinato il coefficiente di aderenza momentaneo fra ruote (10) e rotaia e che al coefficiente di aderenza rispettivamente determinato viene adottato per la correzione della velocità di marcia calcolata.
