Abstract

An obstacle detection device includes a plurality of ultrasonic sensors and a detection control unit. The detection control unit detects an object by using one of at least two of the ultrasonic sensors as a transmission sensor that transmits an ultrasonic wave and the other of the at least two of the ultrasonic sensors as a reception sensor that receives the ultrasonic wave transmitted by the transmission sensor and reflected. A difference of heights of the one used as the transmission sensor and the other used as the reception sensor attached to a surface of a vehicle body from a ground is a predetermined threshold height that is defined based on twice a height of a bump on the ground as a non-detection object.
