Abstract
A control device which executes the following control based on image information acquired by a camera: When the vehicle is traveling outside a trolley wire linkage section C, the control device executes control to give a yaw moment to the vehicle so that the vehicle travels while tracing a trolley wireR/L. When the vehicle is traveling in the trolley wire linkage section C, the control device performs control not to execute the control to give the yaw moment. Further, the control device converts the acquired image information into coordinate information. Based on the coordinate information, when the vehicle is traveling outside the trolley wire linkage section C, the control device calculates a representative point of the vehicle and a target point situated on the trolley wireR/L and gives a yaw moment to the vehicle so that the representative point approaches the target point.
