ABSTRACT:
A detection range adjusting system of an obstacle detection apparatus for a vehicle having a transmitting-receiving unit mounted on the vehicle for transmitting a detection signal directed over a predetermined range and receiving a reflection signal of the detection signal is provided. This system comprises a detection range setting means for processing the reflection signal and setting a detection range for detecting an obstacle which is included within the predetermined range and narrower than the predetermined range, a standard reflecting body positioned at a predetermined position relative to the vehicle, a standard position storing means for storing a standard position of the standard reflection body in the detection range beforehand, and an adjustment instructing means for instructing transmission of a detection signal for adjustment of the detection range. Setting of the detection range setting means is changed so that a detected position of the standard reflecting body in the detection range detected based on a reflection signal of the detection signal transmitted according to the instruction of the adjustment instructing means coincides with the standard position stored in the standard position storing means.
