Abstract
The detection region to which the electromagnetic wave from a vehicle is transmitted ahead in a direction of movement of the vehicle in order to detect an obstacle such as another vehicle in front or the like, is composed of a first detection region looking slightly upward with respect to the road surface and a second detection region looking slightly downward with respect to the road surface. Received signal strengths of reflected waves in the first and second detection regions are compared with each other. When the two received signal strengths are substantially equal to each other, the vertical angle of the object detecting apparatus is judged adequate. When the received signal strength of the reflected wave in the upper-side, first detection region is larger, the angle is judged downward. When the received signal strength of the reflected wave in the lower-side, second detection region is larger, the angle is judged upward and the angle for attachment of the object detecting apparatus is adjusted automatically.
