Abstract
A turning control system for use in a track-laying vehicle comprising: a steering motor for driving crawler belts provided at both sides of the vehicle such that a relative travel difference is caused between the crawler belts, thereby turning the vehicle rightwards or leftwards; a steering instructing device which can be displaced from a neutral position by operation and which instructs, in accordance with its displacement direction and displacement distance, a turning direction and a turning radius for the vehicle, the turning radius decreasing as the displacement distance increases; a displacement detector for detecting the displacement of the steering instructing device; a vehicle speed detector for detecting the vehicle speed at which the vehicle moves forwards or backwards; and a steering motor revolution speed control unit for controlling the revolution speed of the steering motor such that the revolution speed of the steering motor becomes proportional to the vehicle speed detected by the vehicle speed detector at least in the region of low vehicle speeds, when the steering instructing device is displaced and kept in a certain position and therefore there is no change in the displacement of the steering instructing device detected by the displacement detector.
