Automatic braking apparatus with ultrasonic detector
First Claim
1. An automatic braking apparatus comprising:
- an ultrasonic-wave generating circuit including an oscillator and an emitter formed on a front portion of a first car operatively producing an ultrasonic wave signal frontwardly in a predetermined distance in front of the first car;
an ultrasonic-wave receiving circuit including a receiver receiving a reflected ultrasonic wave signal reflected from a second car in front of the first car within the predetermined distance of said ultrasonic-wave generating circuit, an amplifier circuit operatively amplifying the received reflected signal, a relay actuated by said amplified signal for outputing a voltage, and a transforming and rectifying circuit transforming and increasing the voltage and rectifying a current for outputing a direct current; and
a driving means driven by said direct current by said transforming and rectifying circuit and operatively intermittenly operating a brake system for braking the first car for automatic braking purpose.

Abstract
An automatic braking apparatus includes: an ultrasonic wave emitter provided in a front portion of an automatic braking car producing and emitting ultrasonic waves frontwardly in a predetermined distance in front of the car, an ultrasonic receiver also formed in a front portion of the car operatively receiving a reflective ultrasonic wave signal as reflected by another car positioned within the pre-determined distance in front of the automatic braking car for actuating a driving motor to intermittently drive a brake master cylinder to boost brake oil towards two wheel cylinders of front and rear wheels to brake the car intermittently for automatically braking the car for a safe braking purpose.
