What is the Internet of Vehicles?

1. First of all, what is "Internet of Vehicles"?

The concept of Internet of Vehicles (Internet of Vehicles) is derived from the Internet of Things, which is based on the intra-vehicle network, the inter-vehicle network and the vehicle mobile Internet. It is a large system network for wireless communication and information exchange between vehicles, roads, pedestrians and the Internet, etc. It is an integrated network that can realize intelligent traffic management, intelligent dynamic information services and intelligent vehicle control. It is the Internet of Things technology. Typical applications in the field of transportation systems.

After reading so much, it is still not clear? Simply translated, the Internet of Vehicles is: the car is a local area network, the car and the car form an inter-vehicle network, and the car network and the Internet are connected. Intelligent transportation, intelligent car, intelligent driving and other functions.

So what needs can the Internet of Vehicles meet, where are we now, and when will it arrive? These are the questions that everyone cares about most and wants to know about. At present, there should be no unified conclusion from all walks of life at home and abroad. The following only represents my personal opinion.

2. What needs can the Internet of Vehicles meet?

Have you ever had such an experience. The lane you are in is motionless, and the cars in the lane next to you are passing fast one after another. In fact, it is just because an accident happened in front of your lane. If the cloud saves high-precision map data in the future, each car has GPS positioning and an "eye", and the car can report the abnormal situation found to the cloud. Then, when you are about to drive through the accident section, you can receive an early warning and change your driving lane or route in advance, and you can avoid congestion. At the same time, every car on the road can become an "electronic police". At this time, traffic violations and even the crime rate of the whole society will be greatly reduced (refer to the "Sky Eye System" in "Speed 7").

When a call comes in while you're listening to music, the car can automatically lower the volume. When the air quality in the car deteriorates, the car can automatically open the appropriate windows or activate the air conditioner for you according to the weather conditions outside (even the position of the sun and the direction of the wind). When you wait at the red light and find a beautiful woman sitting next to a Lamborghini... In short, after the arrival of the Internet of Vehicles era, driving will become smarter and more fun.

Are you worried about the danger when you use your mobile phone while driving? After the arrival of the Internet of Vehicles, the car can actively explore the surrounding environment through its own sensors. When a possible collision is found, it will immediately give an early warning and even actively slow down for you to avoid danger.

3. What stage of the Internet of Vehicles are we in now?

If we divide the Internet of Vehicles into stages, I think we can refer to the development process of the mobile Internet.

In the first stage, mobile phones (not referring to big brothers) entered the country before 2000, when they could only meet the needs of high-end people.

After entering the second stage, the mobile phone is popularized, the price is reduced, the production capacity is increased, the brand is increased, and gradually covers every family. But at this time, mobile phones still meet the point-to-point communication needs of making calls and sending text messages.

Then came the third stage, when Nokia, Moto, Dopod and other smart phones were born, with wap, Monternet and java applications. Mobile phones can not only meet the needs of peer-to-peer communication, but also connect individuals with the world. At this time, the mobile Internet is exposed.

Finally, in the fourth stage, which is now, with the improvement of scientific research capabilities, the improvement of infrastructure, the further reduction of sensors and the rapid development of industrial manufacturing levels, the touch-screen interactive experience brought by Apple's Android smartphones has emerged. Mobile The Internet really came, and it swept everything by storm. In my opinion, the Internet of Vehicles is only just entering the third stage. That is to say, basic popularization has been completed, and networking capabilities have begun, but it is far from the era of large-scale outbreaks.

So the fourth question comes, when will the Internet of Vehicles arrive?

I think the following objective circumstances are required:

1. The introduction of more unified automotive industry standards. The unified communication protocol and standard configuration between different car brands can be opened to the outside world conditionally, which can solve the problem of the universality of the Internet. The "closed door" will be breached by the Internet sooner or later.

2. The comprehensive popularization of high-precision maps. The width, slope, and surrounding environment of each road are all digitized. The cloud can pick up on the tiniest changes to each car.

3. Sensor technology needs to be further developed. The price and volume of equipment such as lasers, radars, and cameras need to be reduced, and the capabilities need to be stronger.

4. Faster network transmission and ECU processing speed. The time for the vehicle to interact with the cloud becomes shorter, and the local computing power in the vehicle is greatly enhanced.
