1) IEEE 100BASE-TX

- Puisano ea Duplex simplex

- MLT-3 (phetisetso ea maemo a mangata) - > 125Msps (sampole tse limilione / motsotsoana) 65~80MHz bandwidth)

- Lipara tse peli tse sothehileng - ha ho na likhoutu tsa tokiso ea phoso

- Ha ho na theknoloji ea ho hlakola echo le crosstalk ho DSP

Tekatekano ea Maikutlo a Qeto (DFE)

2) IEEE 1000BASE-T - puisano e feletseng ea duplex

- 4D-PAM5 - > 125Msps (disampole tse milione ka motsotsoana) 65~80MHz bandwidth) - lipara tse 'nè tse sothehileng

3. Ethernet VS bese ea setso

3.1 Puisano ea marang-rang e thehiloeng ho switjha

1) Li-node tsohle tsa libese tsa setso li hokahane sebakeng se le seng sa phetiso; mohlala, li-terminal node tse ngata (ECUs) li ka hokelloa beseng e le 'ngoe ea CAN, 'me matšoao a motlakase beseng ea CAN a ka ama liteishene tsohle tse khomaretsoeng beseng.

Ka kakaretso, re bitsa CAN joalo ka CAN Bus kapa CAN Network.

2) Ethernet ke mokhoa oa puisano oa marang-rang o fetotsoeng, moo li-node tsohle tsa li-terminal li lokelang ho kopanngoa ka li-switches 'me boitsebiso bohle bo fetisitsoeng bo lokela ho fetisoa ka li-switches. u se ke ua bua ka bese ea Ethernet, empa ho e-na le marang-rang a Ethernet.

4. Kopo ea Ethernet ka holim'a board

4.1 Ponahalo ea setšoantšo sa moeeng – khokahanyo ea lebelo le holimo

1) Broadcom BroadR-Reach, 100 Mbit / s, duplex e felletseng, para e sothehileng - e nkela lithapo tse turang tse sirelelitsoeng sebaka.

- Puisano ea litsela tse peli

2) Sebelisa bandwidth e phahameng

3) Phallo ea video e thehiloeng ho MAC e nang le litlhoko tse thata tsa nako

4) Mesebetsi e ntlafetseng ea ADAS (lik'hamera tse eketsehileng, radar ea millimeter-wave, laser radar, joalo-joalo) - qeto e phahameng le sekhahla sa foreimi, khatello e fokolang.

- E hloka sekhahla sa phetisetso ea 1000Mbit/s le ho feta

4.2 Ethernet joalo ka marang-rang a mokokotlo oa bokahare ba koloi

Bese ea likoloi tsa nakong e tlang e tla nkela bese ea CAN sebaka ka Ethernet e le marang-rang a mokokotlo, 'me li-subnet li tla etsoa ka balaoli ba libaka tse ngata. Libese tsa puisano tsa FlexRay. Li-domain controllers tse fapaneng li hokahane ka Ethernet ea ts'ebetso e phahameng joalo ka marang-rang a mokokotlo, 'me phapanyetsano ea data e lemohuoa ka liheke tsa Ethernet, kahoo ka kopanelo ba theha meralo ea E / E e thehiloeng ho balaoli ba domain.

4.3 On-board Ethernet bakeng sa phetiso ea matla

Power over Ethernet (POE) ke thekenoloji e ka fetisang data holim'a lithapo tse sothehileng ha ka nako e le 'ngoe e matlafatsa lisebelisoa tsa ho qetela tse hokahaneng, ho felisa tlhoko ea lithapo tsa motlakase tse kantle bakeng sa liteishene le ho fokotsa ho rarahana ha phepelo ea motlakase.

Litšobotsi tsa mantlha tsa phepelo ea motlakase ea sistimi e tloaelehileng ea phepelo ea motlakase ea POE ke:

1) Motlakase o pakeng tsa 44-57V, o nang le boleng bo tloaelehileng ba 48V.

2) Boholo bo lumelletsoeng hona joale ke 550mA, 'me boholo ba ho qala hona joale ke 500mA.

3) Mokhoa o tloaelehileng oa ho sebetsa hona joale ke 10-350mA, 'me hona joale ho sibolloa ha boima bo feteletseng ke 350-500mA.

4) Tlas'a maemo a se nang moroalo, boholo ba tlhoko ea hajoale ke 5mA.

5) Fana ka litekanyetso tse hlano tsa likopo tsa matla bakeng sa lisebelisoa tsa PD (Power device) ho tloha ho 3.84 ho ea ho 12.95W, ka boholo ba 13W.

4.4 Ts'ebetso e se nang mohala ea on-board Ethernet Wireless function ke monyetla o mong oa Ethernet ea on-board.WiFi e boetse e na le mefuta e fapaneng bakeng sa tšebeliso ea likoloi - WAVE (Wireless Access in Vehicle Environments) .Kenyelletso ea on-board Ethernet ntle le pelaelo e tla ba sehlohlolo se molemo ka ho fetisisa bakeng sa ho khothaletsa ho hlahisoa ha theknoloji ea puisano e se nang mohala WAVE lebaleng la likoloi, e fanang ka motheo oa 'mele. bakeng sa ho kenya ts'ebetsong ea limmapa tsa molumo le video le litlhaloso tse phahameng ka puisano ea nako ea sebele, hape e fana ka sebaka se eketsehileng sa mehopolo bakeng sa tšebeliso ea theknoloji ea V2X.
