Claims (1)

[Scope of utility model registration claims] (1) A vehicle automatic acceleration system consisting of the following: B. Speed controller: The speed controller consists of a speed setter, speed indicator, comparator, magnetic switch, and its circuit. The speed setter can arbitrarily set a target value. The comparator compares the difference value between the target value set in the speed setting device and the feedback signal from the speed indicator, controls the operation of the magnetic switch based on the current signal, and corrects the DC servo motor. Rotate or reverse. B. Control switch: The control switch is used to switch between conventional acceleration and automatic acceleration operation of the vehicle. C. DC servo motor: The DC servo motor directly drives the following pulley set, thereby moving the operating rod of the accelerator pump to perform automatic acceleration and deceleration operations. D. Pulley set: The pulley set consists of a small pulley, a rope, and a large pulley. The small pulley is mounted on the axis of the DC servo motor. The large pulley is mounted on the acceleration pump operating rod, and the two pulleys are connected and transmitted by a transmission rope. E. Brake switch: The brake switch is located between the DC servo motor and the speed controller through a circuit and controls the operation of the speed controller. (2) Vehicle acceleration and deceleration operations using the speed controller, DC servo motor, and pulley set are performed by setting the speed setter to a certain target value, and using a comparator to compare the feedback signal of the speed indicator with the set target value. , generates a difference value, and when this difference value is less than zero, the comparator controls the magnetic switch to continuously rotate the DC servo motor in the forward direction, and this forward rotational movement drives the pulley set. Move the acceleration pump operating rod to continue accelerating the vehicle,
When the difference value becomes 0, the comparator controls the magnetic switch to stop the rotation of the DC servo motor and move the vehicle at a constant speed, and when the difference value becomes greater than 0, the comparator controls the magnetic switch. The switch is controlled to continuously rotate the DC servo motor in reverse, and this reverse rotation drives the pulley set to reverse rotation, so the acceleration pump operating rod decelerates the vehicle due to the inertia of the spring. The system of claim 1. 3. The system of claim 1, wherein the control switch causes the vehicle to perform conventional acceleration and automatic acceleration operations. (4) When the driver depresses the brake pedal, the brake switch closes, causing the DC servo motor to rotate in reverse, and at the same time, the speed controller loses its action for a while, causing the vehicle to decelerate; 2. The brake switch according to claim 1, wherein when the driver releases his/her foot from the brake pedal, the brake switch opens, and the series of operations caused by closing the switch disappears, and the vehicle continues to accelerate normally. system.
