Abstract
In an object sensing member M, while electromagnetic waves are transmitted from transmission membersandto a predetermined region, based upon a result of receiving electromagnetic waves reflected from an object by reception membersand, a distance detecting memberdetects at least a distance of the object. An abnormal condition judging member Mjudges that the object sensing member Mis under abnormal condition, if a difference between a maximum value of reception levels of the electromagnetic waves received by the reception membersand, and a minimum value of these reception levels for a predetermined time measured by a time measuring member Mis smaller than a predetermined threshold value. As a result, the abnormal condition judging member Mcan surely judge the abnormal condition even, if the vehicle is driven on a desert road where objects to be sensed are occasionally present.
