    • PROBLEM TO BE SOLVED: To broadly and accurately detect the position and shape of an obstacle, and a space in the periphery of a vehicle. SOLUTION: A transmission wave is transmitted from elements arranged in an array shape, and a reflected wave from the obstacle is received by each of the elements. The distance to the obstacle is calculated from reception times of received signals, and the direction of the obstacle is calculated from phase differences of the received signals in the respective elements. For broadly detecting an obstacle, the phase differences of the transmission signals input to the respective elements are changed properly to control the combined directivity of the transmission wave, and coefficients multiplied to the received signals of the respective elements are changed properly to control the combined directivity of a reception wave. In particular, the directivity is switched alternately between a narrow angle and a wide angle, by setting the phase difference alternately into the same phase or the reverse phase between the adjacent elements, to enable broad-range detection of the position of an obstacle. The position and shape of an obstacle, and a space in the periphery of a vehicle travel route can be realized, based on positional information detected while traveling. COPYRIGHT: (C)2010,JPO&INPIT

    • 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
