Namuhla, imboni yezimoto ithuthuka kancane kancane ngaphansi kobuholi bobuchwepheshe obuhlukahlukene obusezingeni eliphezulu.Ngokuthuthuka okukhulu ezinhlelweni ezithuthukisiwe zokusiza abashayeli (ADAS), amasistimu e-infotainment, kanye nobuchwepheshe bokushayela okuzenzakalelayo, isidingo somkhawulokudonsa ezimotweni zesimanje siyakhula.Amakhono ashintsha njalo kanye nobuchwepheshe obuvelayo budala izidingo ezinkulu zedatha, futhi kubalulekile ukucubungula idatha ngezindlela ezintsha.Esikhathini esedlule, izidingo zokusetshenziswa kwezimoto zendabuko bezikhawulelwe kumasistimu okulawula u-chassis noma amasistimu okulawula umzimba, okudinga kuphela umthamo wokudlulisa idatha wezinkulungwane zamabhithi ngomzuzwana (kbps).Namuhla, izimoto ezihlakaniphile zifakwe inombolo enkulu yezinzwa, amasistimu e-infotainment asezingeni eliphezulu, nezinhlelo zokulawula ukuzulazula ezisekelwe kubuhlakani bokwenziwa (AI) nokufunda komshini (ML), namamojula amaningi e-LIDAR, i-RADAR, namakhamera akhiqiza ama-terabytes edatha. , okuholela ekwandeni okuphawulekayo kobunzima.Ngakho-ke, kubalulekile ukusebenzisa i-Ethernet yezimoto ekuxhumekeni kwesivinini esikhulu, okuthembekile, kanye ne-ultra-low-latency.
Izidingo zobuchwepheshe zezintambo ze-Ethernet zezimoto (ngaphandle kwezixhumi).
Izicaciso ze-OPEN Alliance (TC2 100Mbps, TC9 1000Mbps) zichaza ngokucace kakhulu izimfuneko zamakhebuli e-automotive Ethernet ngaphandle kwezixhumi.I-OPEN Alliance ichaze izidingo eziyisisekelo zamakhebuli adingekayo - imingcele yokusebenza efanele (amanani asekelwe kumazinga ahlukene okuqondiwe):
I-Impedance Z —> igama elithi 100Ohm lezigaba zokubekezelelana ezihlukene
Ukulahlekelwa kokufaka i-IL—ijika elibushelelezi > amazinga esilinganiso ahlukene—kuncike ebuningini
Buyisela ukulahleka kwe-RL —> izimfuneko zesilinganiso ngokuya ngefrikhwensi
Ukulinganisa ukusebenza kwe-LCL1 ne-LCTL2—> amanani nokwakhiwa kwekhebula kuncike ezidingweni zamafrikhwensi ahlukene
Ukunciphisa ukuhlanganisa—> kusebenza kuphela ezintanjeni ezivikelekile
Ukuvikela Ukusebenza—> kusebenza kuphela ezintanjeni ezivikelekile
I-Automotive Ethernet cable head Enterprise, LEONI China
I-LEONI njengamanje ingumholi embonini yamakhebula ezimoto, izindinganiso eziningi zamanje zekhebula zisekelwe kumigomo yayo ecacisiwe, sekuyisikhathi eside ijoyina i-OPEN, IEEE3 kanye ne-SAE4 nezinye izinhlangano zomfelandawonye, futhi ibambisane namalungu omfelandawonye ukuthuthukisa i-100Mbit/s kanye 1Gbit/s izintambo ze-Ethernet zezimoto.I-LEONI Dacar iwuphawu lwekhebula yedatha yezimoto ye-LEONI, ehlanganisa ikakhulukazi amakhebula edatha angama-coaxial kanye nama-multi-core, intambo ye-LEONI yezimoto ye-Ethernet ngenxa yezidingo zayo zedatha ifakiwe ochungechungeni lwe-Dacar, uchungechunge lwe-LEONI Dacar lubandakanya izinhlelo zokusebenza zedatha ezahlukene emotweni, yamanje i-LEONI Dacar 100 Gigabit kanye ne-Gigabit Ethernet imikhiqizo ihlonyiselwe futhi yasetshenziswa kahle kumamodeli amaningi omhlaba wonke we-German, American, brand ezimele kanye namanye ama-OEM.U-LEONI akagcini lapho, u-Lenny uzibophezele ukweqa lelo zinga.Izintambo ze-Dacar Ethernet ze-LEONI zichaza izici zokudlulisela ezifana nezimfuneko zokulahlekelwa kokuguqulwa kwemodi kumakhebuli angavinjiwe.Idizayini yekhebula elineshehethi iqinisekisa ukuthi ihhanisi lifakiwe linemiphumela emibi emincane ngaphansi kwezimo ezinjengokuguga, ukungcola kanye nomswakama.Ekufakweni okuzwela i-EMC, i-LEONI inikeza ukusetshenziswa kwezintambo ezivikelekile ze-LEONI Dacar Ethernet.Lezi zintambo sezivele zakhiwe ngobuningi futhi zisetshenziswa ezinhlelweni zamakhamera we-panoramic.
I-Ethernet marketFuture market
Ngenxa yokuthi i-Ethernet yasungulwa ngaphambi kwesikhathi kakhulu, ukudluliswa kolwazi lwesikhathi sangempela akuzange kucatshangelwe.Ngenani elikhulu lezokuzijabulisa ezilalelwayo nevidiyo ezingena ku-cockpit, inani lama-ECU kanye nesidingo samandla wekhompiyutha we-ECUs kubonise ukukhula okuqhumayo, okusobala kakhulu enkathini ye-ADAS kanye nenkathi ezayo yokungashayeli, kanye nesidingo se-computing bandwidth. isiqalile nokuqhuma.Lokhu kuye kwabangela ukwanda okukhulu kwezindleko zezinhlelo ze-elektroniki zezimoto, ngakolunye uhlangothi, ukwanda kwenani kanye nekhwalithi yezinhlelo ze-ECU, ngenxa ye-computing esabalalisiwe, inani elikhulu lezinsiza zekhompiyutha lichithwa, futhi sikhuluma ngemoto. I-Ethernet isebenzisa ipheya elilodwa lezintambo ezingavinjiwe nezixhumi ezincane nezihlangene kakhulu, kusetshenziswa ipheya engavinjiwe esontekile ingasekela ibanga lokudlulisela elingu-15m (kumapheya asontekile avikelekile angasekela ama-40m), lokhu kucubungula kokuthuthukisa kwenza i-Ethernet yezimoto ikwazi ukuhlangabezana nezidingo ze-EMC yemoto.Yehlisa izindleko zokuxhuma emotweni ngokufika ku-80% nesisindo sezintambo emotweni sifike ku-30%, i-PHY ye-100M Automotive Ethernet isebenzisa ubuchwepheshe be-1G Ethernet ukuze inike amandla ukuxhumana okubili ekuphekweni okukodwa ngokusebenzisa ukukhanselwa kwe-echo.I-Conventional PoE yakhelwe i-Ethernet enamapheya angu-4 amakhebuli, ngakho i-PoDL yathuthukiswa ngokuqondile ukuze i-Ethernet yezimoto inikeze i-12VDC noma i-5VDC kagesi yokuhlinzeka ngokusebenza okuvamile kwe-ECU yeyunithi yokulawula ye-elekthronikhi epheyani elilodwa lezintambo.Yiqiniso, isidingo somkhawulokudonsa siphinde sibe isici, futhi izinzwa ezihlukahlukene, ikakhulukazi i-lidar namakhamera anesinqumo esiphezulu, kufanele zidlulisele idatha zisebenzisa i-Ethernet.
I-Automotive Ethernet ubuchwepheshe bontanga kuya kontanga lapho inodi kagesi ngayinye ixhunywe ngokulandelana.Iswishi isetshenziswa kusistimu esiza ukusungula ukuxhumana phakathi kwama-ECU amaningi kanye nethrafikhi yomzila eya kwamanye amayunithi ahlukahlukene kunethiwekhi.I-IEEE yenza ubuchwepheshe bufane nge-100BASE-T1 kanye ne-1000BASE-T1 ye-automotive-proprietary Ethernet amazinga.Inzuzo ebalulekile ye-Ethernet yezimoto ukuthi ibiza kakhulu kunezinye izivumelwano.Izizukulwane ezedlule ezifana ne-CAN kuphela zihlinzeka ngokudlula okungu-10Mb/s, kuyilapho i-Ethernet yezimoto inganikeza izinga lokuxhumana eliyisisekelo lika-100Mb/s kusukela ekuqaleni.Uma kuqhathaniswa namahhanisi ekhebula endabuko, i-Ethernet yezimoto isebenzisa ikhebula engasindi kakhulu futhi esebenzayo ukuze konge isikhala, kuncishiswe izindleko, futhi kunciphise ubunkimbinkimbi.
