A vehicle surroundings monitoring apparatus inputs signals indicative of
images from a stereoscopic camera, a vehicle speed, a steering wheel
angle and a yaw rate and estimates a traveling path of an own vehicle
according to vehicle forward information and traveling conditions of the
own vehicle. The apparatus establishes a traveling region A according to
this traveling path and further establishes a traveling region B based on
at least either of the traveling region A and road information. It is
judged whether a detected solid object is a preceding vehicle or a
tentative preceding vehicle according to the state of existence of the
object in the traveling regions A, B and the preceding vehicle is
outputted to a traveling control unit.
