A plurality of pieces of detection data of a preceding vehicle, which have been collected in a straight line running state in which a self-vehicle and a preceding vehicle are running straight on the same straight line, are extracted as effective detection data. Setting of an inside parameter is automatically changed so that a center of the detection area can coincide with an average center of the preceding vehicle obtained by a statistical treatment of the plurality of pieces of detection data. The above automatic adjusting function is provided in a control circuit 7 of the range finder, and while the self-vehicle is stably running straight on the same straight line while chasing the preceding vehicle, and optical axis adjustment is conducted by operating the automatic adjusting function of the control circuit 7.

[ What is claimed is:] [1.] A method of adjusting a center of a detection area detected by a range finder at an appropriate position for adjusting an axis of said range finder incorporated into a vehicle in which waves are irradiated on a predetermined detection area in front of said vehicle in a scanning manner and detection data including at least positional information on an object to be detected which is located in said detection area is judged and outputted according to said waves reflected on said object to be detected, said method comprising the steps of:obtaining plural pieces of detection data of said preceding vehicle by said range finder, when said vehicle is running straight on a straight line following a preceding vehicle which is running on the same straight line;processing said plural pieces of detection data of said preceding vehicle statistically;judging said appropriate position as an average center of said preceding vehicle; andchanging a parameter of said detection area of said range finder so that said center of said detection area coincides with said appropriate position.
