Abstract
A vehicle following apparatus is able to continuously or successively measure, once a target vehicle to be followed is determined, the distance to the target vehicle in a stable and reliable manner even if the subject vehicle, on which the apparatus is mounted, is momentarily caused to move in the vertical or horizontal direction with respect to the target vehicle. A pair of first and second image sensors including a pair of optical systems are disposed at a predetermined distance from each other for optically sensing a plurality of objects including a preceding vehicle running ahead of the subject vehicle. A first window containing therein an image of the preceding vehicle as sensed by the image sensors is defined on a screen of a display. A second window is also defined on the screen adjacent the first window for catching the background of the preceding vehicle. The position of the first window is controlled to automatically follow the image of the preceding vehicle by measuring the distances to the objects in the respective first and second windows.
