The car can run on its own, without human intervention. Some people think this is intelligence. Cars have joined OS and APP like smart phones. A car with good interaction and service functions is an intelligent car. Some people think that voice interaction can be carried out. People can use mobile phones to project onto car screens, which is called intelligence. These ideas are one-sided. We define the change of automobile attributes. The essential attribute of intelligent cars is intelligent travel space.

Vehicle is the original attribute of automobile. This will not change. The intelligence of this attribute is the intelligence of driving.

The integration of intelligent operating systems, chips and Internet services into automobiles. The car becomes an intelligent terminal. This is the second attribute. This intelligence is interactive intelligence and service intelligence. That is, the two elements of human-computer interaction intelligence.

Different from PC, mobile phone, etc. The car is mobile and a living space. Each car owner spends about half an hour to two hours every day. The third attribute of cars is mobile living space. Spatial intelligence emphasizes the interconnection between intelligent atmosphere and space.

From the perspective of traffic management. Cars are the nodes of traffic management. With intelligence, it is an information receiving and receiving node in the digital traffic space.

Taken together, the essence of intelligent cars is intelligent travel space. The four elements of intelligence are. Driving intelligence, interactive intelligence, service intelligence and spatial intelligence.

According to the international classification. Automatic driving is divided into L1-L5. In the middle and high-end models, L1-L2 is included in the auxiliary driving function. Its main functions are 360-degree panoramic image, constant speed cruise, collision warning, etc. L4-L5 refers to fully automatic driving in vertical scenes. Such as logistics. L5 is fully self-driving.

Both aspects are in the pilot stage. L4 has been applied on a small scale in the vertical field. Google's waymo began testing L5. As for L3, there is no consensus among countries. There is no clear standard here. Tesla claimed they reached L3. Countries have not yet been able to define this level. Under the condition of man-machine co-driving. It is difficult to define the safety responsibility.

The most explicit embodiment of interactive intelligence is as follows. Screens of different sizes and voice interaction appeared in the car. The value of the screen is presentation. If the screen is touched like a mobile phone. This does not meet the requirements of driving safety and convenience. Voice will become the first interaction mode in the car.

Spatial intelligence of transportation system. The car acts as a node, transmitting information to the cloud. Cars operate based on cloud database and road information. Such as speed control, path selection, etc. Cars, roads, and cloud databases are as one. With traffic data management, we can achieve many goals. Optimize the use of time and space resources in transportation system.
