Abstract
An obstacle detection apparatus for vehicles includes: a first probe wave sensor detecting a direct wave distance as a distance to an obstacle by transmitting a probe wave and receiving a reflection wave of the probe wave reflected by the obstacle; a second probe wave sensor receiving the reflection wave to detect an indirect wave distance as a distance to the obstacle by receiving the reflection wave; an approach determinator determining whether the obstacle is present between the first probe wave sensor and the second probe wave sensor and whether the obstacle is approaching the vehicle; and a distance determinator determining an obstacle distance to be less than or equal to a predetermined distance range when the indirect wave distance falls out of the distance range as the obstacle is present between the first probe wave sensor and the second probe wave sensor and the obstacle is approaching the vehicle.
