Iqhaza elibalulekile lobuchwepheshe be-RF ekushayeleni okuhlakaniphile

Ubuchwepheshe be-RF budlala indima ebalulekile ezinhlelweni zokushayela ezihlakaniphile, ikakhulukazi ezisetshenziselwa ukuzuza ukuxhumana okungenantambo nokushintshisana ngedatha phakathi kwezimoto nendawo yangaphandle. Izinzwa ze-radar zisebenzisa ubuchwepheshe be-RF ukuze zithole ibanga, isivinini nesiqondiso sezinto ezizungezile, zinikeze izimoto idatha enembile yokubona indawo ezungezile. Ngokuboniswa nokutholwa kwamasignali e-RF, izimoto zingakwazi ukuqonda izithiyo ezizungezile nezimo zethrafikhi ngesikhathi sangempela ukuze kuqinisekiswe ukushayela okuphephile.

Ubuchwepheshe be-RF abusetshenziselwa ukubona imvelo kuphela, kodwa futhi budlala indima ebalulekile ekuxhumaneni kwezimoto nezinsiza zangaphandle, ezinye izimoto nabahamba ngezinyawo. Ngezimpawu ze-RF, izimoto zingashintshana ngolwazi lwesikhathi sangempela namarobhothi, ingqalasizinda eseceleni komgwaqo nezinye izinto zokusebenza ukuze zithole izimo zomgwaqo nolwazi lwethrafikhi, futhi zinikeze ukusekelwa kwezinqumo kumasistimu okushayela ahlakaniphile. Ngaphezu kwalokho, ubuchwepheshe be-RF buphinde bubambe isikhundla esibalulekile ekumiseni izimoto nasezinhlelweni zokuzulazula. I-Global Positioning System (GPS) ifinyelela ukuma okunembile ngamasignali e-RF. Ngesikhathi esifanayo, kuhlanganiswe nezinye izinzwa ezifana namayunithi okulinganisa angaphakathi (ama-IMU), amakhamera, ama-lidar, njll., kuthuthukisa ngokwengeziwe ukunemba kokuma nokuzinza.

Ngaphakathi emotweni, ubuchwepheshe be-RF busetshenziselwa ukushintshana kwedatha ngesikhathi sangempela phakathi kwamayunithi ahlukahlukene okulawula ukuze kuqinisekiswe ukusebenza okudidiyelwe kwamasistimu ahlukahlukene. Isibonelo, ukuvikela ukuphepha kwemoto nesistimu yesixwayiso sokushayisana iqapha izithiyo ezizungezile ngokusebenzisa izinzwa ze-RF, ikhipha ama-alamu ngesikhathi noma ithatha ngokuzenzakalelayo ibhuleki eliphuthumayo ukuze kuncishiswe izingozi zokuphepha.

Okunye okubalulekile okusetshenziselwa ubuchwepheshe besignali ye-RF ekushayeleni ngobuhlakani ukuthuthukisa ukunemba nokuzinza kokuma kwemoto, ikakhulukazi ezindaweni eziyinkimbinkimbi. Ngobuchwepheshe be-multi-system fusion positioning, izimoto zingahlanganisa amasistimu wokuzulazula ngesathelayithi njenge-GPS, i-GLONASS, i-Galileo ne-Beidou ukuze zithole indawo enembayo ephezulu. Ezindaweni ezinokuncishiswa kwesignali okunzima kanye nomthelela wezindlela eziningi, njengezakhiwo zasemadolobheni eziphakeme kakhulu noma amahubhe, ubuchwepheshe bokuthuthukisa i-RF (njengokuqedwa kwezindlela eziningi kanye nokumiswa komehluko) bungathuthukisa ngempumelelo ikhwalithi yesignali futhi kuqinisekiswe ukuma kwezimoto okuqhubekayo nokunembile.

Ngaphezu kwalokho, ngokuhlanganisa amamephu anembe kakhulu kanye nokuma kwesignali ye-RF, indawo yemoto ingalungiswa ngokusebenzisa ama-algorithms afana nemephu, okuthuthuke kakhulu ukunemba kokuma. Ngokuhlanganisa amasignali e-RF nedatha evela kwezinye izinzwa, amasistimu okushayela ahlakaniphile angafinyelela ukuma okuzinzile nokunembile, aqinisekise ukwethembeka nokuphepha kwezinhlelo zokushayela ezihlakaniphile ezindaweni ezihlukahlukene eziyinkimbinkimbi.
