An object recognition apparatus in a subject vehicle includes a radar unit
for transmitting a plurality of laser beams in a scan range spread in
horizontal and vertical directions of the subject vehicle and receiving a
reflection, a recognition unit for recognizing the object in front of the
subject vehicle based on the reflection, a determination sub-unit in the
radar unit, a calculation sub-unit in the radar unit; and an adjustment
sub-unit in the radar unit. The radar unit is so disposed in the subject
vehicle with a center axis of one of the plurality of the laser beams
aligned with a target angle that the determination sub-unit uses coverage
in the vertical direction of the laser beam being sufficient for
variation of heights of the reflector on the object at a first distance
detected by the radar unit as the predetermined condition for selecting
of the object.
