Abstract
(EN)
The present invention comprises: an override operation sensor that detects an override operation for switching between an automatic driving mode and a manual driving mode; and a selection device for selecting, as a dump truck driving mode, one mode from among the manual driving mode, a manned automatic driving mode and an unmanned automatic driving mode. If the manned automatic driving mode has been selected by the selection device, a controller switches the manned automatic driving mode to the manual driving mode when an override operation is detected by the override operation sensor. If an unmanned automatic driving mode has been selected by the selection device, the controller continues the unmanned automatic driving mode when an override operation is detected by the override operation sensor.

La présente invention comprend : un capteur d'opération de surpassement qui détecte une opération de surpassement pour une commutation entre un mode de conduite automatique et un mode de conduite manuelle ; et un dispositif de sélection destiné à sélectionner, en tant que mode de conduite de camion-benne, un mode parmi le mode de conduite manuelle, un mode de conduite automatique avec pilote et un mode de conduite automatique sans pilote. Si le mode de conduite automatique avec pilote a été sélectionné par le dispositif de sélection, un dispositif de commande commute le mode de conduite automatique avec pilote vers le mode de conduite manuelle lorsqu'une opération de surpassement est détectée par le capteur d'opération de surpassement. Si un mode de conduite automatique sans pilote a été sélectionné par le dispositif de sélection, le dispositif de commande poursuit le mode de conduite automatique sans pilote lorsqu'une opération de surpassement est détectée par le capteur d'opération de surpassement.
