Abstract

Dispositif formant compteur de vitesse moyenne, notamment pour un véhicule automobile, à structure essentiellement électronique. Selon l'invention, le dispositif comporte un premier compteur 14 recevant par l'intermédiaire du capteur 11 des impulsions représentatives de la distance parcourue par le véhicule depuis son départ, tandis qu'un deuxième compteur 18 reçoit des impulsions fournies par une horloge 15 et qu'un circuit diviseur 19 effectue périodiquement le quotient des contenus des compteurs 14 et 18, pour déterminer la vitesse moyenne, cette dernière étant affichée par le circuit d'affichage 21. Le capteur 11 est prévu pour être intercalé au niveau du compteur kilométrique normal du véhicule.
