ABSTRACT OF THE DISCLOSURE An unmanned vehicle is so controlled as to travel along a guide line in response to command signals transmitted from a fixed host computer. The vehicle includes a driving motor, a steering motor, a driving motor chopper, a steering motor chopper, a speed detector, an offset (misalignment away from the guide line) detector, a main CPU, etc. Since detected offset values are directly feedbacked to the main CPU through a steering control interface and the steering motor chopper is directly controlled by the main CPU through the steering interface; it is possible to eliminate other CPUs conventionally provided for turning on or off both the choppers, separately. Further, since the duty ratio of the steering motor chopper is controlled by taking into account various factors such as offset values, offset increment values, vehicle speeds, steering correcting directions, etc., it is possible to stably correct vehicle steering misalignment at high response speed even when the vehicle is travelling at high speed along the guide line. - 47 -
