July 28，The eighth-generation golf is officially offline at FAW-Volkswagen Foshan Factory，It marks a new chapter in China in China。Take a closer look，FAW-Volkswagen officially referred to the eighth-generation golf as "Digital Golf"，Why is this? The reason should start with the eighth -generation golf's electrical architecture。

What is the electrical architecture?

When we know a car，In addition to the intuitive and visible body design、Test driving dynamic assembly and chassis adjustment，often ignores car electrical equipment，I do n’t know that the electrical architecture of the car determines the control performance of the car to some extent，Equivalent to the "nervous system" of the car，Excellent power assembly with high -efficiency electronic bus，Only the strength of ten % can be exerted，Become a truly driving machine，Otherwise, "Simple limbs are simple brains"，It will feel that it is not very smart when it is opened。

Since 1920，Electronic equipment on the car gradually increases，Need to control the electronic line，The concept of automotive electrical architecture came into being。The original electrical architecture consists of copper cable，Due to each function (such as an electric window、lights, etc.) All need to be controlled by separate lines，Electric control part of the weight is too large and expensive seabet loginfor cost，The function that can be implemented Seabetis relatively single，"Ancient Early" electrical architecture is like the "Big Brother" mobile phone in the 1980s and 1990s，Although it can achieve a minority function，But it can only meet the most basic needs。

1986，bosch released Can (Controller at the SAE conference Area network) protocol，Subsequent Mercedes-Mercedes-Benz S-Class (W140) introduced the CAN bus to connect to the vehicle engine and gearbox for the first time，From then on, the electrical architecture of the automobile has been simplified，solved the problem of complex data lines of the automotive electrical system at that time，also reduced design difficulties，Improve production efficiency。CAN bus is the invention of the automotive electrical architecture across the times，Integrated information transmission processing technology makes the hard line connection less 2/3，greatly reduced the complexity and development cost of design，It is still widely used today。

Wish to know，The field of communication has achieved evolution from 2G to 5G in just ten years，The expectation value of users on vehicle communication functions is also getting higher and higher。Cars in the Internet era are more like a mobile information communication terminal，Data transmission volume of car communication equipment to mobile phone、Tablet to see，At the same time, assisting driving technology is becoming increasingly popular，More and more sensors and controllers equipped with cars，Need enough channel transmission information，So Canfd (CAN with Flexible Data -Rate，Can be born with a variable rate) and the Ethernet architecture of the car。

Golf 7 is based on the MQB platform，equipped with CAN bus，Transmission speed is only 500k/s。Digitalization of the eighth -generation golf，Thanks to MQB New upgrade of EVO platform electrical architecture，seabet appCombination of CANFD bus and Ethernet。seabet appWhat are the benefits? CANFD bus transmission speed reaches 2m/s，Four times the bandwidth of the old version brings more possibilities to the eighth -generation golf，and Ethernet transmission up to 100mbits/s，This is equivalent to the computer at home from dial -up online to broadband。

Speaking of the eighth -generation golf itself, MQB EVO's electrical architecture upgrade has brought about?

Full digital cockpit

The eighth -generation golf's car entertainment module adopts Ethernet architecture，Multimedia screen function switching speed faster，Smooth operation，Vehicle entertainment configuration is also richer，More importantly, the eighth -generation golf vehicle system is created based on the Android platform，The function that can be implemented is not too much。

Full touch interaction

The eighth -generation domestic golf retains the overseas version of the touch button design，Human -car interaction is smoother and natural，High 8 understands you more。

higher -level driving assistance system

The new domestic eighth -generation golf is equipped with a newly upgraded camera and millimeter wave radar，Compared with other models equipped with L2 -level auxiliary driving，The new electrical architecture of the eighth -generation golf has improved the reaction speed of the auxiliary driving，Road recognition ability is better。

The new generation of golf has taken a big step in the electrical architecture，Can FD bus and Ethernet lead the same model，Control performance for the vehicle、Vehicle entertainment and auxiliary driving provides better hardware foundations，Fundamentally improves the digitalization level of the vehicle。Although the domestic eighth -generation golf information we currently master is still relatively limited，But what is definitely，The eighth -generation golf is worth trying。
