Abstract
The present invention aims to facilitate easy correction of the center axis of an obstacle detecting apparatus for a vehicle by calculating deflection of the center axis with respect to the vehicle. Each of most obstacles recognized as moving objects is a preceding vehicle,and when the subject vehicle,is moving straight, the preceding vehicle,is detected in a position straight ahead of the subject vehicle,If the optical axis,of the transmitting/receiving section,is oriented straight ahead of the subject vehicle,the preceding vehicle,will be detected on the optical axis,On the other hand, when the optical axis,deviates from the center axis of the vehicle, the preceding vehicle,is detected in a position deviated from the optical axis,by an angle &thgr; m. In this case, the value &thgr; of deflection of optical axis,is equal to −&thgr; m. In addition, by determining whether or not the relative velocity vector component of an obstacle is within a given range, the accuracy of calculation can be bettered with data of vehicles moving in an adjacent lane and data of vehicles moving along a curve being removed.
