ABSTRACT:
An apparatus is provided for detecting a distance between cars, which apparatus is capable of continuously measuring the distance between one's own car and a preceding car even if the preceding car is moving as far as possible within the visual field of the apparatus. The apparatus is also capable of distinguishing which one of a plurality of preceding cars is being measured for distance, and of simultaneously measuring the distance to another car traveling in parallel to one of the preceding cars.
