Abstract
PURPOSE: To deliver the sense of distance to a driver or the like effectively by a method wherein the frequency of a sound utilized for informing is varied in accordance with a detected distance upon detecting the distance between a movable body and an obstacle and informing it by the sound to the driver or the like.
CONSTITUTION: When a signal produced in an oscillating circuit 1 is emitted to the outside of a car or the like through an oscillator not shown in the diagram and is reflected by the obstacle, the reflected signal is received by a receiver, then, is amplified in the amplifying circuit 6 and is inputted into a comparating and deciding circuit 7, here, a time difference between the reflected signal and a signal from the oscillating circuit 1, that means an information (a) about a distance to the obstacle, is detected. This distance information (a) is converted into an oscillating frequency in an oscillating circuit 11, thereafter, is amplified by an amplifier 12, then, is converted into a sound having a frequency in accordance with the distance information (a) in a speaker 13 to inform it to the driver or the like. According to this method, the variation of the distance between the car or the like and the obstacle may be caught by the sound varying in the frequency thereof and safety driving may be effected.
