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.
