Abstract

See full text

An ultrasonic type object detection apparatus sequentially detects a distance between an ultrasonic sensor and an object in a coverage of a transmission wave at a predetermined detection cycle based on a time taken for the ultrasonic sensor to transmit the transmission wave and then to receive a reflection wave. The apparatus includes: a storage storing the distance to the object; a vehicle information acquisition device acquiring vehicle information for calculating a movement distance; a detection distance predictor predicting a next detected distance to the object based on a past detection result and the vehicle information; and a short range determinator determining whether the object is present in a short range area in which the distance between the object and the ultrasonic sensor is equal to or shorter than a short range threshold.
