Abstract
A method and apparatus for detecting the traveling position and direction of an unmanned vehicle of an autonomous guidance system, wherein pairs of marks are provided along a course on which the unmanned vehicle is to travel and disposed perpendicularly to the course respectively, and at the unmanned vehicle are provided sensors which can detect the marks and specify the relative positions of the marks with reference to the traverse direction of the vehicle body, thereby obtaining the traveling position and/or direction of the vehicle by the relative positions of each pair of marks and a time difference between the time points when either of the marks and another mark being detected respectively or a travel distance between the time points in time. Hence, the traveling position and direction can be accurately and rapidly detected and a shift of the vehicle from the guide course can be quickly eliminated.
