Masiku ano, makampani opanga magalimoto akupita patsogolo motsogozedwa ndi matekinoloje osiyanasiyana otsogola.Ndi kupita patsogolo kwakukulu pamakina othandizira oyendetsa madalaivala (ADAS), ma infotainment system, komanso ukadaulo woyendetsa galimoto, kufunikira kwa bandwidth m'magalimoto amakono kukukulirakulira.Kuthekera kosinthika nthawi zonse ndi matekinoloje omwe akubwera kumapangitsa kuti pakhale zofunikira zazikulu za data, ndipo ndikofunikira kukonza deta m'njira zatsopano.M'mbuyomu, zosoweka zamagalimoto achikhalidwe zinali zongoyang'anira ma chassis kapena machitidwe owongolera thupi, zomwe zimangofuna mphamvu yotumizira ma data masauzande a bits pamphindikati (kbps).Masiku ano, magalimoto anzeru ali ndi masensa ambiri, makina apamwamba kwambiri a infotainment, ndi machitidwe oyendetsa maulendo oyendayenda pogwiritsa ntchito luntha lochita kupanga (AI) ndi kuphunzira makina (ML), ndipo ma modules angapo a LIDAR, RADAR, ndi kamera amapanga ma terabytes a deta. , zomwe zimapangitsa kuti pakhale kuwonjezeka kwakukulu kwa zovuta.Chifukwa chake, ndikofunikira kupititsa patsogolo Ethernet yamagalimoto pamalumikizidwe othamanga kwambiri, odalirika, komanso otsika kwambiri.
Zofunikira zaukadaulo zamagalimoto a Ethernet zingwe (zopanda zolumikizira).
Mafotokozedwe a OPEN Alliance (TC2 100Mbps, TC9 1000Mbps) amafotokoza momveka bwino zofunikira zamagalimoto a Efaneti opanda zolumikizira.OPEN Alliance yafotokoza zofunikira pazingwe zofunikila - magawo ogwirira ntchito oyenerera (miyezo yotengera mitengo yosiyanasiyana):
Impedance Z -> dzina 100Ohm pamitundu yosiyanasiyana yololera
Kutayika kwa IL-njira yosalala> milingo yosiyanasiyana-kumadalira pafupipafupi
Kubweza kutayika RL -> zofunikira pamlingo kutengera pafupipafupi
Kulinganiza magwiridwe antchito LCL1 ndi LCTL2—> mitengo ndi kapangidwe ka chingwe zimatengera zofunikira za ma frequency osiyanasiyana
Kuphatikizira kuchepetsa—> kumakhudza zingwe zotetezedwa zokha
Kuteteza Mwachangu—> imagwira ntchito pazingwe zotetezedwa zokha
Magalimoto Efaneti chingwe mutu ogwira ntchito, LEONI China
LEONI pakali pano ndi mtsogoleri pamakampani opanga makina amagetsi, zambiri zomwe zimagwiritsa ntchito zingwe zamakono zimachokera ku ndondomeko zomwe zafotokozedwa, zakhala zikugwirizana ndi OPEN, IEEE3 ndi SAE4 ndi mabungwe ena amgwirizano, ndikugwirizana ndi mamembala a mgwirizano kuti apange 100Mbit / s ndi 1Gbit/s zingwe zamagalimoto Efaneti.LEONI Dacar ndi mtundu wa chingwe cha data cha LEONI, chomwe chimaphatikizapo zingwe za coaxial ndi ma multi-core data, chingwe cha LEONI automotive Ethernet chifukwa cha zofunikira zake za data chimaphatikizidwanso mu mndandanda wa Dacar, LEONI Dacar mndandanda umaphatikizapo kugwiritsa ntchito deta zosiyanasiyana mgalimoto, pa LEONI Dacar 100 Gigabit ndi Gigabit Efaneti zopangira zidakhala ndi zida ndipo zimagwiritsidwa ntchito bwino m'mitundu yambiri yapadziko lonse ya Germany, America, zodziyimira pawokha ndi ma OEM ena.LEONI sakuyimira pamenepo, Lenny akudzipereka kupyola muyeso umenewo.Zingwe za LEONI's Dacar Ethernet zimatanthawuza mawonekedwe otumizira monga zofunikira zotayika zosinthika pazingwe zosatetezedwa.Mapangidwe a chingwe cha sheathed amatsimikizira kuti harness imayikidwa ndi zovuta zochepa pamikhalidwe monga ukalamba, zonyansa ndi chinyezi.Pamakhazikitsidwe a EMC-sensitive, LEONI imapereka kugwiritsa ntchito zingwe zotetezedwa za LEONI Dacar Ethernet.Zingwezi zapangidwa kale kwambiri ndipo zimagwiritsidwa ntchito pamakamera apanoramic.

Chifukwa Ethernet idapangidwa molawirira kwambiri, kutumiza zidziwitso zenizeni sikunaganizidwe.Ndi kuchuluka kwa zosangalatsa zomvetsera ndi mavidiyo zomwe zimalowa mu cockpit, chiwerengero cha ECUs ndi kufunikira kwa mphamvu zamakompyuta za ECUs zawonetsa kukula kwakukulu, zomwe zikuwonekera kwambiri mu nthawi ya ADAS ndi nthawi yomwe ikubwera yosayendetsa, komanso kufunikira kwa computing bandwidth. yayambanso kuphulika.Izi zachititsa kuwonjezeka kwakukulu kwa mtengo wamagetsi amagetsi, kumbali imodzi, kuwonjezeka kwa chiwerengero ndi khalidwe la machitidwe a ECU, chifukwa cha kugawidwa kwa makompyuta, kuchuluka kwazinthu zamakompyuta kumawonongeka, ndipo tikukamba za galimoto. Efaneti pogwiritsa ntchito zingwe ziwiri zosatetezedwa ndi zolumikizira zing'onozing'ono komanso zophatikizika, kugwiritsa ntchito zopindika zosatetezedwa zimatha kuthandizira mtunda wa 15m kufala (kwa awiri opindika otetezedwa amatha kuthandizira 40m), kukhathamiritsa kumeneku kumapangitsa kuti Efaneti yamagalimoto ikwaniritse zofunikira za EMC zamagalimoto.Kuchepetsa mtengo wamalumikizidwe agalimoto mpaka 80% ndi kulemera kwa waya mgalimoto mpaka 30%, PHY ya 100M Automotive Ethernet imagwiritsa ntchito ukadaulo wa 1G Ethernet kuti athe kulumikizana kwanjira ziwiri pawiri imodzi pogwiritsa ntchito kuletsa kwa echo.PoE ochiritsira lakonzedwa Efaneti ndi 4 awiriawiri zingwe, kotero PoDL anapangidwa makamaka Efaneti magalimoto kupereka 12VDC kapena 5VDC kotunga voteji kwa ntchito yachibadwa ya ECU wa unit kulamulira magetsi pa awiri zingwe.Zoonadi, kufunikira kwa bandwidth ndi chinthu, ndipo masensa osiyanasiyana, makamaka makamera a lidar ndi okwera kwambiri, ayenera kutumiza deta pogwiritsa ntchito Ethernet.
Automotive Efaneti ndiukadaulo wolumikizana ndi anzawo momwe node iliyonse yamagetsi imalumikizidwa motsatizana.Kusintha kumayikidwa mudongosolo lomwe limathandiza kukhazikitsa kulumikizana pakati pa ma ECU angapo ndi kuchuluka kwa magalimoto kumagawo ena osiyanasiyana pamanetiweki.IEEE imayimilira ukadaulo kudzera mu 100BASE-T1 ndi 1000BASE-T1 zoyendera zamagalimoto zama Ethernet.Ubwino wofunikira wa Ethernet yamagalimoto ndikuti ndiyotsika mtengo kuposa ma protocol ena.Mibadwo yam'mbuyo monga CAN imangopereka 10Mb / s kupyolera, pamene Ethernet yamagalimoto imatha kupereka njira yoyankhulirana ya 100Mb / s kuyambira pachiyambi.Poyerekeza ndi zingwe zomangira zingwe zamagalimoto, Ethernet yamagalimoto imagwiritsa ntchito makina opepuka kwambiri komanso ogwira mtima kuti asunge malo, kuchepetsa ndalama, komanso kuchepetsa zovuta.
