ABSTRACT:
An automatic travelling apparatus which permits: determination of a permissible travelling area on the basis of images taken by an image pickup device or video camera, showing the sight of the area appearing ahead of the vehicle; steering control of the vehicle to go into a target course in the permissible travelling area; and selection of a predetermined way of a selected crossing or branch in the target course.
For the image pickup device or video camera taking images of the area extending ahead of the vehicle for determining a permissible travelling area, a wide-angle camera, a telescopic range camera and an ordinary camera are selectively used to meet particular situations for example, taking pictures of a crossing, zigzag way or straight long way. This selective use of cameras of different characteristics permits correct identification of particular roads with those stored in the map storage.
