Abstract
An object detection apparatus is arranged to detect the distance to the object and includes: a transceiver repeatedly transmitting a wave as an ultrasonic wave and receives a reflection wave of the transmission wave; a transmission controller controlling the transceiver to transmit the transmission wave; a distance calculator calculating a distance to the object, based on a time interval from a moment when the transceiver transmits the wave to a moment when the reflection wave is received; and a transmission timing controller controlling timing at which the transmission controller controls the transmission wave to be transmitted. Moreover, the transmission timing controller inserts at least one type of temporary waiting time between a transmission/reception period in which the transceiver transmits the transmission wave and receives the reflection wave and a next transmission/reception period, when a predetermined crosstalk identification condition is established based on the distance to the object.
