Ngokukhula kwesidingo sezimoto zabagibeli nezimoto zezentengiselwano, izinto zikagesi zezimoto zisetshenziswa kabanzi ezimotweni.Ukuze kuqinisekiswe ukusebenza okuvamile kwalezi zisetshenziswa zikagesi ohlelweni oluzinzile lokuphakelwa kukagesi, kubalulekile ukunqoba inkinga yokuphazanyiswa okukhulu kazibuthe kagesi okukhiqizwa izimoto ngesikhathi sokusebenza, okusabalele ohlelweni lokuphakelwa kukagesi ngokuhlanganisa, ukuqhutshwa, kanye nemisebe, ukuphazamisa ukusebenza kwemishini esebhodini.Ngakho-ke, indinganiso yamazwe ngamazwe i-ISO 7637 ibeke phambili izidingo zokungavikeleki zemikhiqizo ye-elekthronikhi yezimoto ekunikezeni amandla.
Izinga le-ISO 7637, elaziwa nangokuthi: Izimoto zomgwaqo-Ukuphazamiseka kukagesi okukhiqizwa ukuqhutshwa nokuhlangana, kuyindinganiso yokuhambisana kagesi yezimoto ze-12V kanye ne-24V yamandla kagesi.Kuhlanganisa kokubili ukukhuthazela kwe-electromagnetic kanye nezingxenye ezikhishwayo zokuhlola ukuhambisana kwe-electromagnetic.Wonke lawa mazinga acacisa izidingo zepharamitha zamathuluzi nezinto zokusebenza ezingasetshenziselwa ukukhiqiza kabusha izingozi zikagesi nokwenza izivivinyo.Kusukela namuhla, izinga le-ISO 7637 selikhishwe ngezingxenye ezine.Kusukela namuhla, izinga le-ISO 7637 selikhishwe ezingxenyeni ezine ukukhombisa izindlela zokuhlola namapharamitha ahlobene ngokuphelele.Bese sizokwethula ikakhulukazi ingxenye yesibili yaleli zinga, i-ISO 7637-II, esetshenziselwa ukuhlola ukuhambisana kwethebhulethi yethu eqinile.
I-ISO 7637-II ibiza ukuqhutshwa kwesikhashana kukagesi emigqeni yokunikezela kuphela.Icacisa izivivinyo zebhentshi zokuhlola ukuhambisana kokwenziwa kwezinto ezidlulayo zikagesi ezifakwe ezimotweni zabagibeli nasezimotweni ezilula ezithengiswayo ezifakwe isistimu kagesi engu-12 V noma izimoto zentengiso ezifakelwe isistimu kagesi engu-24 V–kokubili umjovo kanye nokukalwa kwezinto ezidlulayo.Ukuhlukaniswa kokuqina kwemodi yokwehluleka kokuvikeleka kwesikhashana kuyanikezwa.Isebenza kulezi zinhlobo zezimoto zomgwaqo, ezingancikile ohlelweni lokushayela (isb. ukuthungela inhlansi noma injini yedizili, noma injini kagesi).
Ukuhlolwa kwe-ISO 7637-II kufaka phakathi amagagasi kagesi esikhashana ahlukene.Amaphethelo akhuphukayo nawayo alawa mapulses noma amagagasi ayashesha, ngokuvamile ebangeni le-nanosecond noma le-microsecond.Lokhu kuhlolwa kwamandla kagesi wesikhashana kuklanyelwe ukulingisa zonke izingozi zikagesi izimoto ezingase zihlangabezane nazo ngaphansi kwezimo zomhlaba wangempela, okuhlanganisa nokulahlwa kwempahla.Ukuqinisekisa ukusebenza okuzinzile kwezinto ezisemkhunjini kanye nokuphepha kwabagibeli.
Ukuhlanganisa ithebhulethi ehambisana ne-ISO 7637-II emotweni kunikeza izinzuzo eziningi.Okubaluleke kakhulu, ukuqina kwabo kuqinisekisa ukusebenza kwesikhathi eside nokusebenza okuthembekile, ukunciphisa izindleko zokunakekelwa nokwandisa umkhiqizo jikelele.Okwesibili, ithebhulethi ehambisana ne-ISO 7637-II eqinile ihlinzeka ngokubonakala kwesikhathi sangempela kanye nokulawulwa kolwazi olubalulekile, ithuthukise ukuxilonga imoto nokwandisa ukusebenza kahle.Okokugcina, lawa maphilisi angakwazi ukuxhumana ngaphandle komthungo namanye amasistimu ezimoto namadivayisi angaphandle, athuthukise ukuxhumana nokusebenzisana.Ngokunamathela kuleli zinga, singakha ukwethembeka, sigxilise ukwethenjwa, futhi silethe imikhiqizo ephakeme ehlangabezana nezidingo zamakhasimende.
Ngokuhambisana ne-ISO 7637-II ukuvikelwa kwamandla kagesi wesikhashana, amaphilisi amatshe asuka ku-3Rtablet akwazi ukumelana nokushayisana kwezimoto ezifika ku-174V 300ms futhi asekele ukunikezwa kwamandla kagesi okubanzi kwe-DC8-36V.Ithuthukisa ngempela ukuqina kokusebenza kwamasistimu emoto abalulekile afana ne-telematics, i-interfaces yokuzulazula kanye nezibonisi ze-infotainment ngaphansi kwezimo ezinzima futhi ivimbele ukulahlekelwa okubangelwa ukungasebenzi kahle.
