Iinkcukacha zeengozi zibonisa ukuba ngaphezu kwe-76% yeengozi zibangelwa kuphela yimpazamo yabantu;kwaye kwi-94% yeengozi, impazamo yomntu ifakiwe.I-ADAS (IiNkqubo zoNcedo loMqhubi oPhezulu) ixhotyiswe ngeenzwa ezininzi ze-radar, ezinokuxhasa kakuhle yonke imisebenzi yokuqhuba okungekho mntu.Ewe kunjalo, kuyafuneka ukucacisa apha, iRADAR ibizwa ngokuba yiRadio Detection kunye nokuRangi, esebenzisa amaza onomathotholo ukubona kunye nokubeka izinto.
Iisistim zangoku zerada ngokuqhelekileyo zisebenzisa i-24 GHz okanye i-77 GHz iifrikhwekhwethe zokusebenza.I-advanteji ye-77GHz ilele ekuchanekeni kwayo okuphezulu kokusukela kunye nokulinganisa isantya, isisombululo esingcono se-engile ethe tyaba, kunye nevolumu ye-eriyali encinci, kwaye kukho ukuphazamiseka okuncinci kophawu.
Iirada zomgama omfutshane zihlala zisetyenziselwa ukutshintsha i-ultrasonic sensors kunye nokuxhasa amanqanaba aphezulu okuqhuba ngokuzimeleyo.Ukuza kuthi ga ngoku, abenzi boluvo baya kufakwa kuzo zonke iikona zemoto, kwaye i-sensor ejonge phambili yokukhangela umgama omde iya kufakwa phambi kwemoto.Kwi-360 ° inkqubo ye-radar egcweleyo ye-radar yomzimba wesithuthi, izinzwa ezongezelelweyo ziya kufakwa phakathi kwamacala omabini omzimba wesithuthi.
Ngokufanelekileyo, ezi zinzwa zeradar ziya kusebenzisa ibhendi ye-79GHz kunye ne-4Ghz yokuhambisa i-bandwidth.Nangona kunjalo, umgangatho wothumelo lwesantya somqondiso wehlabathi okwangoku uvumela kuphela i-1GHz bandwidth kwisitishi se-77GHz.Namhlanje, inkcazo eyisiseko ye-radar MMIC (i-monolithic microwave edibeneyo yesiphaluka) "i-3 iziteshi zokuhambisa (TX) kunye ne-4 yokufumana iziteshi (RX) zihlanganiswe kwisekethe enye".
Inkqubo yokuncedisa umqhubi enokuqinisekisa i-L3 nangaphezulu kwemisebenzi yokuqhuba engaqhutywanga ifuna ubuncinci iinkqubo ezintathu zoluvo: ikhamera, iradar kunye nobhaqo lwelaser.Kufuneka kubekho izinzwa ezininzi zohlobo ngalunye, zisasazwe kwiindawo ezahlukeneyo zemoto, kwaye zisebenza kunye.Nangona iteknoloji ye-semiconductor efunekayo kunye nekhamera kunye ne-radar sensor technology development ikhoyo ngoku, ukuphuhliswa kweenkqubo ze-lidar kusengowona mngeni mkhulu kunye neyona nto ingazinzanga ngokwemiba yezobugcisa kunye nezorhwebo.
