Yini i-ethernet
I-Car Ethernet iyinhlangano entsha yendawo yenethiwekhi esebenzisa i-Ethernet ukuxhuma iyunithi ye-elekthronikhi emotweni. Ngokungafani ne-Ethernet yendabuko, esebenzisa izintambo ezi-4 ezisontekile ezisontekile, i-ethernet yemoto ingafinyelela isilinganiso sokudlulisa se-100mbit / s noma ngisho ne-1Gbit / s ku-pair eyodwa esontekile yamakhebuli asontekile. Ngasikhathi sinye, futhi ihlangabezana nezidingo zomkhakha wezimoto ngokuthembela okuphezulu, imisebe ye-electromagnetic ephansi, ukusetshenziswa kwamandla okuphansi, ukwabiwa kwe-bandwidth, i-latency ephansi yesikhathi sangempela. Ungqimba lomzimba we-Ethernet ebhodini elisebenzisa ubuchwepheshe be-BroadrReach, kanye nobuchwepheshe be-Broadr-Fian's Global Ngakho-ke, kwesinye isikhathi ibizwa ngokuthi i-Rreach (BRR) noma i-OABR (i-Open Alliance BroadR ebanzi). Ungqimba lwe-mac we-Ethernet wemoto amukele i-IEEE 802.3 ejwayelekile ejwayelekile futhi exhasa ngaphandle komthungo asetshenziswa kabanzi protocols ane-level yenethiwekhi ephezulu (njenge-TCP / IP) ngaphandle kokuzivumelanisa nezimo.

On-board ethernet protocol ukwakhiwa kwezakhiwo
I-Ethernet ethwalwa ngemoto kanye nokwakhiwa kwayo okusekelwa okuphezulu kwe-Upper-ureyer namanye amaphrothokholi noma amafomu ezicelo.

Uhlaka lwe-Ethernet uhlaka
Phakathi kwazo, i-AVB ukunwetshwa kwemisebenzi yendabuko ye-Ethernet, ethuthukisa ukusebenza kwesikhathi sangempela sokuhanjiswa komsindo wendabuko kwendabuko kanye nokwengeza ukuvumelanisa kwewashi okuqondile, ukubhuka komkhawulokudonsa nezinye izimiso zokudlulisa ze-Real-Time and Video ngekhono elikhulu lokuthuthuka. Ezinye izinsiza ze-Middle / IP (ezinamathele ezisezingeni elisezingeni eliphakeme nge-IP) zicacisa izidingo zokuxhumana zevidiyo zokuxhumana kwezimoto zemoto, ezingasetshenziswa emkhakheni wamakhamera wemoto, futhi zibona ukulawulwa kwemodi kosizo lomshayeli ngama-API.

Njengokwandiswa kwephrothokholi ye-AVB, amanethiwekhi abucayi besikhathi (i-TSN) wethula ubuchwepheshe obuhlobene we-Ethernet-ye-Ethernet ngesikhathi, ongakuthola kahle ukudluliswa kwemininingwane yokulawula izimoto. Ngaphezu kwalokho, i-Ethernet ese-Ethernet ye-1Gbit Communication Standard futhi isekela amandla ngomsebenzi we-Ethernet (Poe) nomsebenzi osebenza kahle we-Ethernet (EEE). Umsebenzi we-POE uhlinzeka ngama-Power ngamadivayisi we-terminal axhunyiwe ngenkathi udlulisela idatha ngamakhebula amabili asontekile, eqeda isidingo sokuxhuma izintambo zamandla zangaphandle eziya kuma-terminals kanye nokunciphisa ubulukhuni bokunikezwa kwamandla.

On-board Ethernet scradization
Ngokwe-In-Vehicle Ethernet ejwayelekile, i-IEEE802.3 ne-IEEE802.1 Amaqembu asebenzayo, i-Autosar, i-Alliance Open Alliance ibambe iqhaza elikhulu ekuthuthukiseni.
I-IEEE802.3 I-Local Network Standard yendawo imele izinga elijwayelekile le-Ethernet embonini, futhi ubuchwepheshe be-Ethernet techneet buthuthukiswa ngesisekelo se-IEEEE802.3, ngakho-ke i-IEEE njengamanje iyinhlangano ebaluleke kakhulu ye-Ethernet . Ukuze uhlangabezane nezidingo zemoto, kufaka phakathi ukuthuthukiswa kwezincazelo ezintsha ezintsha kanye nokubuyekezwa kokucaciswa kwalolokuqala kwamaqembu amabili asebenzayo e-IEEEE802 no-802.1, kufaka phakathi imininingwane ye-PHY, kanye nocingo olulodwa lwedatha Ukuhlinzekwa kwamandla komugqa. Ngaphezu kwalokho, i-AVB ehlobene nokudluliselwa kwe-AV, ukuvumelanisa nesikhathi kanye nokunye ukucaciswa nakho kudinga ukulinganiswa ngamanye amakomidi e-technical e-IEEE, njenge-IEEE1722 ne-IEEE1582.

Vula umfelandawonye
I-Open Policmical Alliance yethulwe ngoNovemba 2011 nge-Broadcom, NXP, kanye neBMW ukukhuthaza ukusetshenziswa kwamazinga we-Ethernet-based technology to-car ukuxhumana. Umgomo wokumaphakathi okuphambili ukuthuthukisa izinga le-100Mbit / R elombhalo engokomfanekiso futhi uthuthukise izidingo zokusebenzisana ezivulekile.

Amaqhuda
I-AutoSar i-Consortium yabakhiqizi bezimoto, abahlinzeki, kanye nabathuthukisi bethu abahlose ukuthuthukisa ukwakhiwa kwesoftware evulekile, evamile, futhi ukucaciswa kwe-autosar sekuvele kufaka phakathi i-TCP / UDP / IP Protococol Stack.

Uhlobo
I-AVNU Alliance yasungulwa yi-Broadcom ngokubambisana ne-Cisco, eHarman kanye ne-Intel ukukhuthaza izinga elijwayelekile le-IEEE 802.1 AVBB kanye ne-Time Synchronization Network (TSN) Engajwayelekile, bese ulungisa izingqinamba ezibalulekile zezobuchwepheshe nezobuchwepheshe ezifana nesikhathi esiqondile, sangempela Ukuvumelanisa -I-Synchronization, Ukubhukelwa komkhawulokudonsa, kanye nokwakheka kwezimoto.
