ABSTRACT:
In a moving object, such as automobile, having a steering gear which determines a traveling course, and a traveling distance detector which detects a traveling distance; a direction detection apparatus comprising a steering position detector detecting an amount of displacement of the steering gear, and an arithmetic unit which calculates a traveling direction of the moving object from a steering position signal proportional to the amount of displacement and a traveling distance signal proportional to the traveling distance, thereby to detect the traveling direction of the moving object. The apparatus can detect the traveling direction without being affected by a magnetic deviation, an abnormal magnetic field, etc.
