Abstract

The present invention relates to a backup detector device for detecting distant and close obstacles and method thereof, wherein ultrasonic probe of the backup detector device alternately emits ultrasonic signal of high level and low level energies. When the high level ultrasonic signal is emitted, the ultrasonic signal can be transmitted to a far distance to detect a distant obstacle, and when the low level ultrasonic signal is emitted, an obstacle in a close distance from a vehicle can be detected because the time period that residual vibration of the signal lasts is short. Thus, the present invention effectively realize detection of both distant and close obstacles, and as compared with the detection range of the conventional backup detector, the present invention provides an expanded detection range with enhanced accuracy of detection.
