A movable body controlling device for improving the flexibility and maintainability of an operation control system for movable bodies in which the running control of movable bodies can be effected by allowing ultrasonic signals to be transferred between movable bodies without any intervention by a ground device. An ultrasonic signal transmitter (1) is provided on a train (A) and an ultrasonic signal receiver (10) and a signal-processing circuit (13) are provided on another train (B), timings of transmitting and receiving ultrasonic signals are synchronised by means of a timing signal-generating circuit (2, 11) provided on respective trains, and ultrasonic signals are transmitted and received via a metallic transmitting medium (30). The signal-receiving train (B) measures the transmitting time of ultrasonic signals by means of the signal-processing circuit (13) and produces information needed to control the trains based on the measured value. L'invention porte sur un dispositif de commande de corps mobiles améliorant la souplesse et la facilité d'entretien du système de gestion de l'exploitation de corps mobiles servant à commander les déplacements desdits corps au moyen de signaux ultrasonores transmis entre lesdits corps sans intervention d'équipements au sol. Un émetteur (1) de signaux ultrasonores est placé sur un train (A), et un récepteur de signaux ultrasonores (10) associé à un circuit de traitement des signaux (13) est placé sur un autre train (B). Les rythmes des signaux émis et reçus sont synchronisés à l'aide de générateurs de signaux de synchronisation (2, 11) placés sur chacun des trains, tandis que les signaux ultrasonores sont émis et reçus par l'intermédiaire d'un milieu émetteur métallique (30). Le train recevant les signaux (B) mesure le temps de propagation des signaux ultrasonores au moyen du circuit de traitement (13) et produit les informations nécessaires à la commande des trains en fonction des valeurs mesurées.
