Imodyuli yeSango leMoto: "Iziko leMithambo" leeMoto ezikrelekrele kunye nokuphendula okungalunganga
Phantsi kobuchwepheshe beemoto obukrelekrele nobuqhagamshelweyo, iimoto ziye zaguquka ukusuka kwizithuthi ezilula zoomatshini zaya kwiingqokelela ezintsonkothileyo zeenkqubo ze-elektroniki nezombane. Kule nkqubo, imodyuli yesango lemoto idlala indima ebalulekileyo njenge "nerve center", esebenza njengomguquleli okrelekrele kunye nomthumeli osebenzayo ukuqinisekisa unxibelelwano oluhamba kakuhle phakathi kweenkqubo ezahlukeneyo ze-elektroniki ngaphakathi kwesithuthi. Nangona kunjalo, ukuba le ndawo iphambili iyasilela, imisebenzi emininzi yesithuthi iya kuchaphazeleka, kwaye nokhuseleko lokuqhuba lunokuba sengozini.
Umsebenzi oPhambili weModyuli yeSango leMoto
Uguqulelo lweProtocol kunye noQhagamshelwano lweNxibelelwano Izithuthi zanamhlanje zixhotyiswe ngeeyunithi ezininzi zolawulo lwe-elektroniki (ECU) ezifana nombane, itshasi, umzimba, kunye neenkqubo zokuzonwabisa. Ezi yunithi zisebenzisa iinkqubo ezahlukeneyo zonxibelelwano ezifana ne-CAN, i-LIN, kunye ne-Ethernet, njenge "sebe elithetha iilwimi ezahlukeneyo". Umsebenzi oyintloko we-gateway module kukusebenza "njengomguquleli", ukuguqula imiqondiso evela kwiiprotokholi ezahlukeneyo ukuqinisekisa ukutshintshiselana kolwazi oluhamba kakuhle phakathi kweenkqubo. Umzekelo, isignali yesantya evela kwinkqubo yamandla kufuneka iguqulwe yi-gateway ngaphambi kokuba iboniswe ngaxeshanye kwideshibhodi nakwisikrini sokuzonwabisa; isignali ye-LIN evela kwi-door control module nayo kufuneka iguqulelwe yi-gateway ngaphambi kokuba ibonwe yi-CAN bus yenkqubo yamandla.
Ucwangciso Lokubaluleka Kwedatha Ngexesha lokusebenza kwesithuthi, amakhulu eepakethi zedatha aveliswa ngomzuzwana. Imiqondiso yeebhuleki, izilumkiso zokungqubana, kunye nenye idatha enxulumene nokhuseleko kufuneka idluliselwe kuqala, ngelixa idatha yokuzonwabisa efana nokudlala umculo kunye nohlaziyo lokuhamba inokucutshungulwa kamva. Imodyuli yesango inamandla okucwangcisa akrelekrele, yabela i-bandwidth ngokwemigaqo ephambili ye-ISO 11898: imiyalezo enxulumene nokhuseleko ineyona nto iphambili, ilandelwe yimiyalezo yenkqubo yamandla, kwaye eyona iphantsi kwimiyalezo yenkqubo yokuzonwabisa. Le ndlela yokulawula ithintela ngempumelelo idatha engabalulekanga ethatha i-bandwidth, iqinisekisa ukuba imiyalelo engxamisekileyo idluliselwa ngesantya se-millisecond kwaye ithintela iingozi zokhuseleko ngenxa yokuxinana kwedatha.
Ukhuseleko lwe-Intanethi Njengoko izithuthi ezikrelekrele ziqhagamshelwa ngakumbi kwiinethiwekhi zangaphandle, umngcipheko we-intanethi nawo uyanda. Imodyuli yesango "yi-firewall" yokhuseleko lwe-intanethi yesithuthi, kusetyenziswa iteknoloji yokwahlulahlula i-hardware ukwahlula inethiwekhi yesithuthi ibe ngamanqanaba ahlukeneyo okhuseleko, njenge-domain yamandla yokhuseleko oluphezulu kunye ne-domain yokuzonwabisa evulekileyo. Xa imoto ihlaziywa yi-OTA okanye idityaniswe nefowuni yeselula, isango lihluza kwaye liqinisekise idatha yangaphandle ukuthintela ikhowudi enobungozi ekungeneni kwaye liphephe iinkqubo zolawulo eziphambili (ezifana nokuqhuba kunye nokuqhobosha) ekusetyenzisweni ngokungekho mthethweni.
Ukuxilongwa Kwempazamo Nokujongwa Kwemeko Imodyuli yesango ikwathatha umsebenzi wokujonga imeko yazo zonke ii-ECU zesithuthi. Iqokelela idatha yokusebenza ngexesha langempela evela kwii-ECU ezingaphezu kwama-50 kuyo yonke imoto, kubandakanya i-voltage, ubushushu, kunye neekhowudi zempazamo, kwaye iyigcine kwimemori engaguqukiyo. Abasebenzi bokulungisa banokufunda idatha yesango besebenzisa isixhobo sokuxilonga esizinikeleyo, befumana ngokukhawuleza imodyuli ephosakeleyo, benciphisa ixesha lokuxilongwa kwempazamo malunga nama-40%, ngakumbi kwiimpazamo ezithile. Ukongeza, isango linokwenza kwaye lijonge ukusebenza kweenethiwekhi zasekuhlaleni, liqinisekise ukusebenza okuzinzileyo kwenkqubo yenethiwekhi yonke.
Iziphene eziqhelekileyo kunye neempawu zeModule yeGateway yeMoto
Ukusilela Komsebenzi Wezixhobo Ze-elektroniki Eyona nto ibonakalayo yokusilela kwesango kukungasebenzi kakuhle okanye ukusebenza okungaqhelekanga kwezixhobo ze-elektroniki. Umzekelo, iinkqubo zokuzonwabisa ezifana nokuhamba, isandi, kunye neBluetooth azisebenzi kakuhle, imisebenzi yomzimba efana nokutshixa ucango, ukuphakamisa nokwehlisa iifestile, kunye nokungasebenzi kakuhle kokulungiswa kwesibuko sangasemva, kwaye nesikrini solawulo esiphakathi sinokuphinda siqalise kwakhona okanye sibe mnyama. Umnini weBMW 3 Series uxele ukuba kukho ukucima kombane rhoqo kwinkqubo yokuhamba, okwafunyaniswa kamva ukuba kungenxa yojongano lwebhasi ye-CAN oluxiliziweyo kwimodyuli yesango, nto leyo ebangele ukuba ukuhanjiswa kwedatha kuphazamiseke.
Ukukhanya Okungaqhelekanga kwePaneli yeZixhobo Izibane zempazamo Xa isango lingadluliseli ulwazi oluvela kwiinkqubo ezahlukeneyo ngokufanelekileyo, izibane ezichasene nokutyibilika, impazamo yokubhuleka, ibhuleki yesandla ye-elektroniki, ibhegi yomoya, njl.njl. kwiphaneli yezixhobo zinokukhanya zonke, ngelixa iinkqubo ezifanelekileyo zisenokungabi nampazamo. Olu hlobo "lwe-alamu yobuxoki" lunokukhohlisa abanini bemoto, lubangele iinkxalabo ezingeyomfuneko kwaye lubonise ukungaqheleki kokudluliselwa kwedatha kunye nokucutshungulwa kwesango.
Uqhagamshelo lwenethiwekhi kunye nokuqalisa kwesithuthi, ukungaphumeleli kwemodyuli yesango kunokukhokelela kuqhagamshelo olungaqhelekanga lwenethiwekhi yesithuthi, njengokungakwazi ukunxibelelana neenethiwekhi ezingenazingcingo, imiqondiso ye-WIFI ebuthathaka, ethintela ukusetyenziswa kwemisebenzi ekrelekrele efana nokuhamba kwi-intanethi kunye nolawulo olukude. Kwiimeko ezinzima ngakumbi, iingxaki ezifana nokuba imoto ingaqali okanye ivale ngokuzenzekelayo kwisekhondi enye zinokwenzeka. Oku kungenxa yokuba inkqubo yokuqalisa ibandakanya umsebenzi wokusebenzisana weemodyuli ezininzi, kwaye ukungaphumeleli kwesango kunqumla uqhagamshelo phakathi kwazo.
Iingozi ezinokubakho kwinkqubo yokhuseleko Ukuba ukungaphumeleli kwesango kuchaphazela ukuhanjiswa kwemiqondiso yokulawula kwiinkqubo ezibalulekileyo ezifana nokuqhobosha kunye nokuqhuba, kuya kuzisa iingozi ezinkulu zokhuseleko. Umzekelo, umnini we-Audi Q5L ngequbuliso wasebenzisa iibhuleki ngequbuliso waza waphulukana nolawulo lwe-accelerator ngelixa eqhuba. Emva kokuhlolwa, kwafunyaniswa ukuba amanzi angena kwisitulo esingasemva aze antywilisele i-gateway module, nto leyo ebangela i-short circuit kwaye ngaloo ndlela ichaphazela ukusebenza okuqhelekileyo kwenkqubo yamandla.
Impendulo kunye nokuthintela ukungaphumeleli kwemodyuli yesango
Ukugcinwa ngexesha elifanelekileyo kunye nokuxilongwa kobuchwephesha Nje ukuba isithuthi sibonakalise ezi mpawu zingaqhelekanga zingasentla, kuyimfuneko ukuqhagamshelana neengcali zobuchwephesha ngokukhawuleza. Ngesixhobo sokuxilonga, funda idatha yempazamo egcinwe kwisango, kwaye ufumane ingxaki ngokuchanekileyo. Xa ulungisa, kufuneka kubekwe phambili ekukhetheni iindawo zokuqala zefektri. Isango lesibini lefektri linokuba neengxaki zokungahambelani kweprotocol, okubangela iziphene ezintsha ezifana nesithuthi esingangeni kwimo yokulala okanye ibhetri iphelelwa ngamandla. Emva kokutshintsha isango, kuyimfuneko ukusebenzisa isixhobo sokuxilonga somenzi ukubhala ikhowudi yeVIN yesithuthi kunye nolwazi loqwalaselo ukuqinisekisa ukuba imodyuli isebenza ngokuqhelekileyo.
Amanyathelo okulungisa yonke imihla Ngexesha lokuqhuba yonke imihla, kuphephe ukufaka izixhobo ezingasebenzi kakuhle. Ukuba iingcingo ziqhagamshelwe ngqo kumgca wombane wesango, kulula ukubangela umbane ogqithisileyo kwaye utshise imodyuli. Xa uhlamba imoto, qaphela ukungangenisi manzi. Isango lidla ngokufakwa phantsi kwedeshibhodi okanye ecaleni kwesiqu. Musa ukungxama ukutshiza amanzi anoxinzelelo oluphezulu ngqo kwezi ndawo ngesibhamu samanzi, njengoko ukungena kwamanzi kunokubangela iindleko zokulungisa ubuncinci iiyuan ezingamakhulu aliqela. Ukongeza, xa usenza ulungiso rhoqo kwiikhilomitha ezingama-2-3 amawaka, cela ingcali ukuba ijonge iziphelo zocingo zesango, icoce uthuli kunye nee-oxide ukuze kuncitshiswe amathuba okuba kubekho iimpazamo.
Nangona imodyuli yesango incinci ngobukhulu, inxulumene nokusebenza okuqhelekileyo kwemisebenzi emininzi ebalulekileyo yesithuthi. Ukuqonda umsebenzi wayo kunye neempawu zempazamo, ukwenza ulondolozo lwemihla ngemihla kunye nokulungisa ngexesha elifanelekileyo, kunokugcina imoto ekrelekrele ikwimeko entle kwaye kubonelele ngamava okuhamba akhuselekileyo nalula kubaqhubi nabakhweli.
