Abstract
A moving subject recognizing system for recognizing a subject, such as a pedestrian, moving toward a forward path of a vehicle to avoid a collision against the subject scans a field ahead the vehicle to detect a transverse velocity of a subject moving in a transverse direction and a longitudinal distance of the subject in a direction of the traveling path which are compared with a first and a second threshold value, respectively, and recognize that the subject is in danger of entering the traveling path and hit by the vehicle when the transverse velocity is greater than the first threshold value and the variation of the longitudinal distance is smaller than the second threshold value.
