A vehicle control device 50, a controller 100, an inverter control device 30 and a steering control device 32 constitute a control device 200 which executes control to give a yaw moment to a vehicle 1 to make the vehicle 1 travel while tracing a trolley wire 3R, 3L based on image information detected by a camera 15. The control device 200 converts an image acquired by the camera 15 into coordinate information, calculates at least one representative point of the vehicle 1 and at least one target point situated on the trolley wire 3R, 3L based on the coordinate information, and executes the control to give a yaw moment to the vehicle 1 so that the representative point approaches the target point. With this configuration, an electrically driven dump truck capable of lightening the operating load on the driver during the trolley traveling is provided.
An electrically driven vehicle which elevates a slider of a power collector provided on the vehicle to be movable up and down, places the slider in contact with a trolley wire installed along a lane, and travels by using electric power from the trolley wire, comprising:
