Abstract
An obstacle detection apparatus for vehicles includes: a first ultrasonic sensor for detecting a distance to an obstacle; a second ultrasonic sensor at a position of the vehicle for receiving a reflection wave from the obstacle of an ultrasonic wave from the first ultrasonic wave; a notifier that gives a notification of detecting the obstacle present within a preset distance in one or more of predetermined notification areas including a first notification area for the first ultrasonic sensor, and a second notification area for the second ultrasonic sensor detects the obstacle for the vehicle; and a controller that controls contents to be notified by the notifier. Furthermore, the controller determines whether a first indirect wave distance and a second indirect wave distance are used to determine whether to give the notification of detecting the obstacle in the first notification area.
