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.
Claims3
An automatic car speeder control comprising:
- a speed controller comprising speed setting means for retaining a preset speed and generating a signal proportional thereto, speed indicator means for generating a signal proportional to the actual speed, and comparator means for comparing said signals and generating a signal proportional to the comparison;
- a DC servo motor having an output shaft, a small pulley mounted on the output shaft;
- control means coupled between said motor and the output of said comparator means for driving said motor in a direction of rotation responsive to the comparator signal;
- accelerating pump means for controlling the speed of a car having an actuator shaft, a large pulley mounted on said shaft said pulleys being coupled together in a driving relationship whereby said small pulley is the driver and the large pulley is driven by said servo motor to drive said pump means;
- and brake switch means coupled to the controller for selectively activating and deactivating said controller.
