Pedestrian detection function

■
The pre-collision system detects pedestrians
based on the size, profile, and motion of a
detected object. However, a pedestrian may not
be detected depending on the surrounding
brightness and the motion, posture, and angle of
the detected object, preventing the system from
operating properly. (→P. 292)
