Embodiment Construction

[0012] Exemplary embodiments are described below with reference to the accompanying drawings. figure 1 is a block diagram showing an obstacle detection system 1 according to one embodiment.

[0013] like figure 1 As shown, the obstacle detection system 1 includes an ultrasonic sensor 10 , a control device 20 and a display device 30 . The obstacle detection system 1 is installed on a vehicle (not shown) to detect obstacles around the vehicle by using ultrasonic waves.

[0014] The ultrasonic sensor 10 may be a plurality of ultrasonic sensors. For example, a plurality of ultrasonic sensors (eg, four ultrasonic sensors) may be mounted on each of the front and rear bumpers of the vehicle. The ultrasonic sensor 10 includes a microphone (not shown) for emitting ultrasonic waves to and receiving ultrasonic waves from the surroundings. The ultrasonic sensor 10 also includes circuits (not shown) for amplification, reverberation adjustment, sensitivity adjustment, and the like. Ult...

Abstract

An obstacle detection apparatus for detecting an obstacle in its surroundings is disclosed. The system includes: an ultrasonic sensor for transmitting and receiving ultrasonic wave; an obstacle detection section (22) for performing an obstacle detection operation to determine whether the obstacle actually exists, wherein the obstacle detection section (22) determines that the obstacle actually exists when a first voltage level associated with the ultrasonic wave received in the obstacle detection operation exceeds a determination threshold; a noise monitoring section (21) configured to performa noise monitoring operation to determine a noise level, wherein, the noise monitoring section (21) recognizes a second voltage level associated with the ultrasonic wave received in the noise monitoring operation as the noise level; and a determination threshold setting section (23) configured to set the determination threshold based on the second voltage level.

Description

technical field [0001] The present invention relates to an obstacle detection system which detects obstacles around the obstacle detection system by using ultrasonic waves. Background technique [0002] An obstacle detection system that detects obstacles around the system by using ultrasonic waves is described in, for example, JP-2003-270345A. The obstacle detection system disclosed in JP-2003-270345A can operate in a noise determination mode and an obstacle detection mode. In the noise determination mode, the obstacle detection system receives ultrasonic waves from the surroundings without emitting ultrasonic waves from the ultrasonic sensor to the surroundings, recognizes the received ultrasonic waves as noise, and determines whether the voltage level of the noise is greater than or equal to the noise determination value. In the obstacle detection mode, the obstacle detection system transmits ultrasonic waves from the ultrasonic sensor to the surroundings, receives ultras...
