Abstract
An obstacle detection apparatus that detects an obstacle existing around a vehicle is provided to include an ultrasonic sensor and a controller. The ultrasonic sensor is provided in the vehicle at a position having a predetermined height from a road surface. The ultrasonic sensor includes a plurality of ultrasonic elements configured to transmit an exploration wave toward outside of the vehicle, and receive a reflected wave reflected by an obstacle as a reception wave. The controller is configured to derive (i) an obstacle distance and (ii) an obstacle height based on an intensity of the reception wave received by each of the plurality of ultrasonic elements and a phase difference in the reception wave received by each of the plurality of ultrasonic elements.
