摘要：The present invention aims to facilitate easy correction of the center axis of anobstacle detecting apparatus for a vehicle by calculating deflection of the center axiswith respect to the vehicle. Each of most obstacles recognized as moving objects is apreceding vehicle 93, and when the subject vehicle 91 is moving straight, the precedingvehicle 93 is detected in a position straight ahead of the subject vehicle 91. If the opticalaxis 95 of the transmitting/receiving section 31 is oriented straight ahead of the subjectvehicle 91, the preceding vehicle 93 will be detected on the optical axis 95. On the otherhand, when the optical axis 95 deviates from the center axis of the vehicle, the precedingvehicle 93 is detected in a position deviated from the optical axis 95 by an angle θm. Inthis case, the value θ of deflection of optical axis 95 is equal to -θm. In addition, by

determining whether or not the relative velocity vector component of an obstacle iswithin a given range, the accuracy of calculation can be bettered with data of vehiclesmoving in an adjacent lane and data of vehicles moving along a curve being removed.
