At present, cars in China can be roughly divided into two systems. One is the interconnection of car dumpers. The other is the automatic driving system of L2 to L3. Most cars having one of them will have the other. In general cases, cars use both of these two at the same time.

Let's briefly talk about these two systems. The first is the car dumper interconnection system. You can understand it as moving a tablet computer to the car. Through APP, it can realize remote control starting, flameout, positioning and self-checking. The central control screen on the car can realize human-computer interaction. Such as navigating to Beijing, adjusting the temperature of air conditioning, listening to music online, etc.

Then I will talk about the automatic driving technology of L2L3. It can realize ACC adaptive cruise and lane departure warning. In addition, it has collision warning, automatic braking, road identification and other functions.

These two systems exist in most smart cars at the same time. For example, Tesla, BYD, etc. So, what are the necessary things for smart cars?

First, safe. Self-driving cars can avoid active accidents when driving under the constant operation of the electronic radar system of the car. This is beyond the reach of people as drivers. Because when people are drivers, they will have various aspects that cannot be considered. Such as vision, mental attention and mentality. It is impossible to have zero accidents. Of course, this is an active accident. There is no way for others to hit your car.

Second, people will win more time and cost after leaving the driver's operation. In the process of driving, whether it is entertainment or work, you can have more time. This has great advantages for people to relax their psychology and strengthen their study. The common one that makes driving easier is the adaptive cruise function. The speed of the vehicle can be automatically controlled. This control is within the set speed range according to the speed, distance and lane conditions of the whole body. Drivers can drive more easily without stepping on the accelerator and brake frequently.

Third, it is more convenient and faster to reach the destination. After the automobile products realize full-automatic driving, they can avoid some situations with the navigation system. These situations may affect the normal driving of the car. Such as traffic jams and vehicle accidents. This is automatic. It can choose smoother road conditions to reach its destination faster.

In addition, when the vehicle speed is above a certain range, the system can analyze the camera data. Then it will distinguish the identification line of the current lane by itself. If the system recognizes that the vehicle deviates from the lane without turning on the turn signal, it will do automatic correction to ensure the driving stability. The lane keeping system will be connected for a short period when the driver disengages his hand from the steering wheel. This is to keep the vehicle running in the lane. If the driver's hand is off the steering wheel for too long, the car will issue a reminder.

These are all the traits of smart cars. It is not so popular now. But we will realize these one by one in the future.
