摘要： PROBLEM TO BE SOLVED: To provide an object detecting device which does not have any limitations with respect to its detectable object, and is capable of detecting the position of an object. SOLUTION: Ultrasonic sensors 21-24 each having an element D for transmitting a transmission wave and elements A, B, C for receiving reflected waves, are arranged on a rear bumper 7. When the ultrasonic sensor 21 transmits a transmission wave, the directivities of the elements A, B provided in the ultrasonic sensors 22-24 are controlled to wide angles. A distance up to an obstruction is found by the time difference between the time of transmission and the time of reception. Moreover, a horizontal azimuth of the obstruction P is found by the phase difference between received signals at the elements A, B, and a vertical azimuth is found by the phase difference between signals at the elements A, C. Consequently, an obstruction detection range can be widened since a reflected-wave receiving range widens. Moreover, the position of the obstruction can be detected with high accuracy, since the horizontal and vertical positions of the obstruction can be detected. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To determine a low obstacle such as a skid without coming within a close range thereof by a simple and inexpensive configuration.
SOLUTION: A transmitter-receiver 3 is disposed in a position higher than a rear bumper of a vehicle 10, and an ultrasonic wave is transmitted backward to receive a reflected wave from a detecting object. At this time, a peak value of the reflected wave received is detected and stored. The peak value, which changes as the vehicle 10 moves backward, is calculated as a peak value difference. In the event of an obstacle P being close to a road surface that falls outside a detection area S, the peak value difference becomes "negative" to allow determination.
