detection means for detecting the orientation or position of the working machine of the loading machine;
discrimination means for, in correlation between the orientation or position of the working machine that has been detected by the detection means and the direction or position of the boundary line, discriminating whether the working machine of the loading machine has been positioned on the side of the left loading point or positioned on the side of the right loading point;
travel command instruction means for instructing a travel command; and
travel control means for, when a travel command is instructed by the travel command instruction means, giving a travel command to the unmanned vehicle which is to perform loading at the loading point on the side which has been determined through the discrimination means.

Abstract
In giving a travel command to an unmanned vehicle in both-side loading, or in setting a position of a loading point in both-side loading, whether a working machine of a loading machine is positioned on left-loading point side or right-loading point side is discriminated in correlation between an orientation or a position of the working machine when the travel command is instructed and a direction or a position of the boundary line. In setting the position of the loading point in both-side loading, whether the working machine of the loading machine is positioned on left-loading point side or right-loading point side is discriminated in correlation between the orientation or the position of the working machine when position setting of loading point is instructed and the direction or the position of the boundary line.
