Title:
ELECTRIC DRIVE DUMP TRUCK
Document Type and Number:
WIPO Patent Application WO/2012/165046
Kind Code:
A1
Abstract:
In the present invention, a vehicle control device (50), a controller (100), an inverter control device (30), and a steering control device (32) constitute a control device (200) that executes control on the basis of image information acquired by a camera (15) to apply a yaw moment to a vehicle (1) so that the vehicle (1) travels along trolley lines (3L and 3R). Moreover, this control device (200) converts the images acquired by the camera (15) into coordinate information, calculates at least one representative point for the vehicle (1) and at least one target point located on the trolley lines (3L and 3R) on the basis of this coordinate information and executes control to apply a yaw moment to the vehicle (1) so that the representative point will move closer to the target point. With this configuration, an electric drive dump truck is provided that can reduce the operational burden on the driver during trolley travel.
