Gigabit Ethernet makes the new electronic and electrical architecture more efficient
Intelligent electric vehicle era , Car companies not to mind taking the trouble to emphasize the advanced nature of electronic and electrical architecture . Electronic and electrical architecture is the basis of intelligent and digital performance of a vehicle , Equivalent to the central nervous system of the vehicle .BMW iX A new generation of electronic and electrical architecture of BMW Group is adopted . Although BMW Group has not introduced this information in detail before , But one thing is for sure ,BMW iX The electronic and electrical architecture should be a centralized domain control structure .
With the improvement of intelligence and digitization ,BMW iX It's going to generate huge amounts of data . Whether it's the amount of data 、 Or processing speed , It must adopt a more efficient centralized electronic and electrical architecture , Not a distributed architecture .
According to introducing ,BMW iX Equip about 40 Two different sensors are used for various automation and driving assistance functions , The amount of data generated is currently BMW Mass production models 10-20 times . In order to ensure the efficiency of data processing , Its vehicle bus system uses Gigabit Ethernet to transmit data for the first time , The total transmission speed can reach... Per second 30Gbit,10 Times the transmission rate of previous 100M Ethernet .
Over Gigabit Ethernet , The data collected by each sensor of the vehicle will be quickly transmitted to high-performance computers in several domain controllers for processing , So as to ensure the security of various functions and the fluency of user experience .
5G The blessing Data transmission is faster and more reliable
BMW iX It is also the first in the world to adopt 5G Luxury cars with Internet technology .5G Faster data transfer , The average transmission rate reaches 100Mbit/s, The peak transmission rate is up to 10Gbit/s; At the same time, it has the characteristics of low delay and high reliability , It will greatly expand the possibility of vehicle interconnection with the outside world .
stay 5G With the help of Technology , Vehicle information processing 、 entertainment 、 Driving safety 、 There will be significant improvements and innovations in the autopilot function and experience . such as , In car voice conference will be replaced by HD video conference , Users can also watch in the car 4K/8K HD video , Play car online games , The vehicle's AR Live navigation 、 Remote driving , And the function and experience of vehicle road coordination in the future will be improved .

This technology allows users to choose operators more flexibly , Or without unlocking the device 、 Replace the operator on the premise of purchasing new equipment .
eSIM Embedded design will SIM The card is firmly integrated into the on-board communication module , Vehicle specification level embedded system SIM Cards don't because of extreme temperatures 、 humidity 、 Corrosion or turbulence affecting function and reliability . In terms of network selection , Users can also choose operators by themselves and OTA Download the card data of the selected operator into the card , To access the network of the selected operator .
It is worth noting that , BMW in China 5G Functional test verification overcomes many difficulties , Because of Chinese 5G There are many base stations , The location is widely distributed , And connect with three operators , There is no experience to learn from . according to the understanding of , BMW China team takes the lead 、 The multinational team has completed 5G Functional test and verification , Ensure the product quality , Realized 5G and eSIM On time delivery of .
