Abstract

Dispositif susceptible d'être embarqué à bord d'un véhicule terrestre pour détecter et enregistrer les déplacements de ce véhicule sur le terrain. Il comprend des moyens reliés à chacune des roues d'une paire de roues opposées du véhicule pour détecter la vitesse de rotation de chacune desdites roues, des moyens pour fournir des signaux fonction chacun de la vitesse de rotation de chacune desdites roues, des moyens de traitement desdits signaux pour fournir d'une part un signal représentatif de la vitesse du véhicule et d'autre part un signal représentatif de sa direction, et des moyens répondant auxdits signaux représentatifs de la vitesse du véhicule et de sa direction pour commander un enregistreur graphique. Applications, notamment, en agriculture.
