Abstract

Un dispositivo di misurazione di velocità e spazio percorso per veicoli comprende due generatori di valori di misura (3, 4) del numero di giri, indipendenti e connessi ad assi diversi (1, 2) del veicolo. Uno (3) di questi generatori (3, 4) che funge da generatore principale, è collegato a un circuito di calcolo (10) posto a bordo del veicolo. Se il valore di misura fornito dall'altro generatore (4) supera sensibilmente quello fornito dal generatore principale (3), il circuito di calcolo (10) viene automaticamente collegato al generatore (4) che fornisce il valore di misura più elevato (4) (Figura 1).A vehicle speed and distance measuring device comprises two speed measured value generators (3, 4), independent and connected to different axles (1, 2) of the vehicle. One (3) of these generators (3, 4) which acts as the main generator, is connected to a calculation circuit (10) placed on board the vehicle. If the measurement value provided by the other generator (4) significantly exceeds that supplied by the main generator (3), the calculation circuit (10) is automatically connected to the generator (4) which provides the highest measurement value (4) (Figure 1).
