For traditional cars, this will gradually shift from industry to technology. However, for car building, it seems that it is not too difficult. How to build the most intelligent car is the problem that is difficult to solve at present. For intelligent cars, the measure of a product's intelligence is the ability of the chip algorithm behind it, because the demand for computing power of smart cars is much higher than what we have seen.

This leads to a waste of internal computing resources.

The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments may be combined with each other under the condition of no conflict.

First of all, it should be noted that a domain controller means that in the "domain" mode, at least one server is responsible for the verification of each computer and user connected to the network, which is equivalent to the guard of a unit. It is called "domain controller". Controller (DomainController, abbreviated as DC)”. Domain controller (Domain controller, DC) is the storage location of Active Directory, and the computer on which Active Directory is installed is called a domain controller. When Active Directory is installed for the first time, the computer on which Active Directory is installed becomes a domain controller, or "domain controller" for short. Domain controllers store directory data and manage user-domain interactions, including user login processes, authentication, and directory searches. A domain can have multiple domain controllers. For high availability and fault tolerance, smaller domains need only two domain controllers, one for actual use and one for fault tolerance checking; larger domains can use multiple domain controllers. A domain controller contains a database of information such as the account, password, and computers belonging to the domain. When a computer is connected to the network, the domain controller must first identify whether the computer belongs to this domain, whether the login account used by the user exists, and whether the password is correct. If any of the above information is incorrect, the domain controller will deny the user login from this computer. Without being able to log in, the user cannot access rights-protected resources on the server. The domain controller is composed of SOC, power module, switching module, WIFI and other modules. It contains a variety of sensors (camera module, millimeter wave radar module, lidar module, ultrasonic radar module, inertial navigation positioning module), communication (Ethernet, CAN), display (display screen) and other interfaces.

Edge computing refers to the use of an open platform that integrates network, computing, storage, and application core capabilities on the side close to the source of objects or data to provide the most recent services nearby. Its applications are initiated on the edge side to generate faster network service responses and meet the basic needs of the industry in real-time business, application intelligence, security and privacy protection. Edge computing sits between, or on top of, physical entities and industrial connections. With cloud computing, historical data from edge computing can still be accessed.

Cloud computing is a type of distributed computing, which refers to decomposing huge data computing processing programs into countless small programs through the network "cloud", and then processing and analyzing these programs through a system composed of multiple servers. The applet gets the result and returns it to the user. In the early days of cloud computing, simply put, it was simple distributed computing, solving task distribution and merging computing results. Therefore, cloud computing is also called grid computing. Through this technology, the processing of tens of thousands of data can be completed in a very short period of time (several seconds), thereby achieving powerful network services.

At present, the car is divided into power domain, chassis domain, cockpit domain, intelligent driving domain and other parts. In the current intelligent driving field, the method of domain controller is basically used to realize various intelligent functions, and the calculation aspect is more It is an edge computing approach.
