Unmanned vehicle composition

In our daily life, everyone will come into contact with composition. According to the different writing time limit, composition can be divided into limited composition and unlimited composition. I believe many people will find writing difficult. The following is my composition about driverless cars. Welcome to read the collection.

The composition of driverless cars 1 IQ is improving and science is developing. In the near future, high-speed cars will not need drivers to drive.

Human-driven cars are completely controlled by computers. Before driving, first retrieve the distance data from the computer database, then store the driving route and distance data in the computer of the car, and finally activate the driving key. In this way, the driverless car began to drive automatically according to the route set by the computer. During driving, the computer can automatically adjust the speed according to the speed limit of the road section and the number of vehicles. You can also automatically overtake safely or let other vehicles overtake. You can also safely avoid obstacles and automatically sense traffic lights ... people in the car can read books, chat online, play chess and watch TV, sleep and rest ... Finally, when the car arrives at the finish line on time, it will automatically pull over at the designated place and send a signal to reach the finish line.

It is worth mentioning that in addition to the advanced functions mentioned above, the driverless bus is also equipped with intercom and visual monitoring systems at the departure station and terminal, which can not only monitor everything in the car, but also talk to every passenger. In addition, every seat in the car is equipped with an automatic micro cash register, a micro TV, a micro computer and a micro phone for passengers to enjoy at any time.

In addition, the truck has the function of unmanned driving and is equipped with different numbers and types of robot loaders. The delivery office can use the computer to direct the robot to carry the goods.

Students, I'm afraid I can't do it, I'm afraid I can't think of it. Action is not as good as action. From now on, study harder, improve our IQ index, climb the scientific peak bravely, and lay a solid foundation for making all kinds of driverless cars with magical functions as soon as possible!

With the popularization of computers and the Internet, it has become a fact that "a scholar stays at home and knows what's going on in the world". As a new media, countless netizens "rush before dawn" or "dance lightly and enjoy themselves" on the Internet every day. In this year's Science and Technology Festival held by our school, we watched the computer programming made by the information teacher and witnessed its fun and magic.

The teacher stepped onto the platform, took out a "car" and put it on the table. As soon as the computer mouse is clicked, the "car" slowly moves forward. When it travels ten centimeters away from the computer, it immediately stops, gradually retreats, turns around and moves on. At the table, it stopped again, or retreated a little, turned a corner and drove away in the direction of the teacher. Wow, what's going on? The students were stunned, and the friends sitting in the back row stood up.

The teacher smiled. He pointed to a place above the car and said, "We installed a radar on the car. Using the ultrasonic distance sensor, the computer judges the distance between the obstacle and the car by calculating the time difference between sending and receiving reflected ultrasonic waves, and then issues instructions to make the car drive safely. " Oh, I see! Suddenly, it dawned on us.

"That is to say, driverless cars are made with this principle?" I raised my hand and stood up to ask questions. The teacher replied approvingly: "Yes, the driverless car senses the environment around the vehicle through on-board sensors, and controls the vehicle to reach the scheduled destination in the planned driving route." "Then why can't we see driverless cars on the road?" Another classmate asked questions. "This classmate asked very well! Driverless cars have high requirements for the driving environment. Because our roads are narrow and there are many vehicles, pedestrians' traffic safety awareness is not strong enough. For example, someone suddenly ran a red light and crossed the road. You said, if it can't stop, just move on. Or crashed in other places? " "Mm-hmm." Some people nodded frequently, some people bowed their heads in meditation, and some people whispered.

"I hope that driverless cars will enter our lives as soon as possible!" The teacher said.

I have a dream to design a driverless car. Let it become an important symbol of the rapid development of automobile technology in the new century.

The "eyes" of a driverless car are two TV cameras at the right front of the car, which are 50 cm apart from each other. There is a light-emitting device in the camera, which is very powerful. "Eyes" can identify obstacles with a height of more than 10 cm on the platform plane between 5 and 20 meters in front of the car, which is particularly amazing. If there is an obstacle ahead, the eyes will send a signal to the brain. The "brain" will judge whether to pass, bypass, slow down or stop by emergency braking according to the signal and the local actual situation at that time, choose the best scheme, and then instruct the car to stop, retreat or slow down in the form of electrical signals. Replace everyone's orders. Operating the "foot" of a driverless car is to control the steering gear and brakes of driving, so that people can enjoy the riding process without driving.

Many technologies of driverless cars can be explored in the future, and we need to learn more knowledge to realize them continuously. We can expect more meaningful new things. With the development of science and technology, I believe that in the near future, we can all appreciate the elegance of more driverless cars.

Our dreams will come true and create a better tomorrow. The continuous innovation of new technologies has developed rapidly.

As a small designer, there will be more waiting for me to pursue my dreams, and my own ability needs to be constantly improved. I will continue to work in this direction!

Today, the atmosphere at home is not right. Mom hangs her head listlessly. Dad walks around and keeps talking on the phone. I asked anxiously, "What's the matter?" Mom said shyly, "I scraped someone else's car with my car today." Dad shook his head and said, "You female drivers are really road killers!" " "Mother flat flat mouth, and bowed his head.

Seeing my mother so sad, I really want to invent a driverless car.

I want to install an autopilot in the car. As long as you enter the destination, you can automatically plan the route, including the most time-saving route, the shortest distance route, and the scenic spot route for you to choose from. The on-board system will automatically adjust the direction and speed according to traffic jams and speed limit photos. In my opinion, to achieve this, we must rely on the accurate calculation of satellite radar.

I want to install accurate and clear sensors around the car. It can accurately scan the situation around the car and make a judgment in advance: the red light stops, the green light goes, and there is a pedestrian about 150 meters ahead, which seems to be crossing the crosswalk, so slow down and make way in advance. ...

I want to install a propeller on the roof. But the propeller consumes a lot of energy and can only be used in an emergency. It can be used in traffic jams and slippery roads. As soon as it is unfolded, the car flies to a safe and open place like a dragonfly, and then it can move on. How interesting this is!

This kind of car is best to use solar energy, so don't worry that you can't reach your destination without gasoline.

With driverless cars, people no longer have to take a driver's license test; Don't worry about traffic jams; There won't be any traffic accidents ... just close your eyes, sleep and wake up to your destination. It's really beautiful to think about it!
