A system for detecting the presence or absence of a vehicle in front of a subject vehicle and method therefor, wherein a plurality of wave transmitters transmit distance measuring media such as laser beams or electromagnetic waves over a front detection area toward which the distance measuring media are transmitted in mutually different directions and through respectively predetermined angles with respect to a longitudinal axis of the subject vehicle. In the detecting system and method, the presence of the preceding vehicle is determined on the basis of propagation delay between the times at which at least one of the waves is transmitted and at which the reflected waves are received. The lateral progress of the vehicle in front of the subject vehicle from detection area to detection area is monitored to maintain contact with the detected vehicle even around curves or during steering adjustments.

A system for detecting the presence or absence of a vehicle present in a detection area of a subject vehicle on which the system is mounted, comprising: (a) first means for transmitting measuring media over the detection area toward which the measuring media are simultaneously transmitted in mutually different directions and through respectively predetermined angles with respect to a longitudinal axis of the subject vehicle; (b) second means for outputting a first signal upon receipt of any one of the measuring media from the first means reflected by an object which is present in the detection area the subject vehicle, said first signal indicating the direction of propagation of the reflected measuring media toward the object, for calculating a distance between the subject vehicle and the object on the basis of the propagation delay between transmission of the measuring media from the first means and reception of the reflected wave from the object and outputting a second signal indicating the calculated distance between the subject vehicle and the object; and (c) third means for recognizing whether the object is a vehicle present in the detection area on the basis of the first and second signals outputted from said second means.
