Abstract:
A method of recognizing objects located ahead of a vehicle on the basis of reflected waves resulting from a transmission wave emitted ahead of the vehicle within a predetermined angular range, the method comprising the steps of:calculating positions of the objects; calculating a lane-sameness probability for each of the objects that the object and the vehicle are on a same lane; generating object information pieces corresponding to the objects respectively, the object information pieces representing the calculated positions of the objects and the calculated lane-sameness probabilities for the objects; determining whether or not at least two objects among the objects become substantially equal in position; in cases where it is determined that at least two objects become substantially equal in position, recognizing the at least two objects as a single object; selecting one from the at least two objects which relates to a calculated lane-sameness probability equal to or higher than a predetermined value; and causing said single object to take over an object information piece corresponding to the selected object.
