What is unmanned driving?

More than 30 years ago, there were unmanned aircraft in the sky, but unmanned aircraft were not used to carry goods for direct passengers, but were basically used for military purposes, such as reconnaissance, surveillance, communication, electronic countermeasures and ground attacks. The famous American U2 plane is an unmanned reconnaissance plane that can fly at high altitude. People can't help thinking that there are unmanned planes in the sky. Can there be driverless cars on the ground?

The traffic environment on the ground is much worse than in the air. The airspace is large, and the error of a few centimeters on the ground will lead to terrible car accidents, so driverless cars must use the most advanced computers to achieve high output and high level.

There used to be a simple driverless car, which used radio remote control technology, just like radio remote control of airplane model flight. Such a car can only move mechanically on the ground according to people's pre-set procedures, so it is only the prototype of a driverless car.

With the development of electronic computers, it has become the future development trend to equip automobiles with computers. Recently, foreign countries have developed driverless cars, also known as smart cars and computer cars.

This car is equipped with a complete computer system and a TV camera. It can have no driver in the front seat and passengers in the back seat. Cars run as freely as people drive, even better than the most skilled drivers. It runs along the road. If you encounter an obstacle suddenly, the car will stop automatically. When the obstacle is removed, it continues to drive and gallops away until it automatically stops at its destination.

So how does this driverless car work?

There are two cameras on the right front of the driverless car. In fact, it replaces the driver's eyes, observes the traffic situation ahead, and then outputs these signals to the computer for processing. After processing, the computer will issue corresponding instructions, which will drive the wheels of the car, or brake, or turn, or slow down, or speed up. Everything is handy, and passengers sitting in the car don't have to worry at all. Because the accuracy of computer is many times higher than that of human manipulation. In fact, the computer installed in the car is the "driver", and the driverless car is a robot that can run fast.

Of course, this computer car is not perfect, for example, it is still invalid in complex weather, cloudy days and at night, mainly because it is difficult for the camera to judge this situation. However, with the development of science and technology, there will be more advanced and complete computer cars in the future.

One day in the future, people will drive out. You and your partner can get to where you want to go safely and comfortably in the car just by inputting signals such as destination and time. If every car becomes a terminal of the computer system, then millions of cars can be managed by huge computers, and the actions of millions of cars on the ground will be dispatched by a unified traffic command center. What a spectacular and strange sight!
