ABSTRACT:
An automatic car speeder system, which is to make use of a speed controller to control the action of a solenoid valve according to a signal so as to drive a DC servo motor to make a clockwise rotation or a counter rotation; to make use of a selector switch to control the car for regular speeding or automatic speeding; to make use of a servo motor to turn a pulley wheels set to drive a accelerating pump actuating rod for automatic accelerating or decelerating; to make use of the pulley wheels set connected with said DC servo motor and the accelerating pump actuating rod for reciprocal driving; and to make use of a switch of the braking system to control the action of the servo motor to let the accelerating or declerating of the car be stably controlled.
