Iyini i-automotive microwave radar
I-Automotive Microwave Radar uhlelo lwe-radar olusebenzisa ama-microwaves ukuthola ukutholwa, ikakhulukazi okusetshenziswa ezimotweni nasezinye izimoto zomhlaba. I-Microwave Radar ithola izinto ezisendaweni ezungezile ngokuthumela nokwamukela amasiginali we-microwave, ukuze kufinyelelwe imisebenzi ehlukahlukene, njengokutholwa kwezithiyo, isexwayiso sokushayisana, njll.
Umgomo Wokusebenza
I-Automotive Microwave Radar isebenza ngokufana ne-radar ejwayelekile, okungukuthi, ithumela i-wave engenantambo (microwave) bese ithola i-echo ngokuya ngomehluko wesikhathi phakathi kokuthola nokuthola idatha yesikhundla. Ngokukhethekile, ama-radars we-microwave akhipha amasiginali we-microwave athi ahlangane lapho ahlangabezana nezingqinamba, futhi i-radar ibala ibanga ngokulinganisa isikhathi sohambo lokujikeleza kwezimpawu. Ngaphezu kwalokho, i-radar ye-microwave nayo ingathola isivinini nesiqondisi sento ngokuhlaziya izici zesiginali esibonisiwe, njengomphumela we-doppler.
Isimo sohlelo lokusebenza
I-Automotive Microwave Radar inezimo ezahlukahlukene zezicelo ezimotweni:
Isexwayiso sokushayisana: Ngokuthola izithiyo ezingaphambili, isexwayiso sokuqala, siza umshayeli ukuthi athathe izinyathelo zokugwema ukushayisana.
I-Adaptive Cruise Salcent: Iguqula ngokuzenzakalela ijubane lokulawulwa kokuhamba ngesikebhe ngokuya ngezindawo ezizungezile zemoto, ukugcina ibanga elivikelekile kusuka emotweni ngaphambili.
Ukutholwa kwe-Pedestrian: ohlelweni oluzenzakalelayo lokushayela, i-radar microwave ingabona abahamba ngezinyawo nezinye izithiyo ukuze baqinisekise ukuphepha okushayela.
Ukupaka okuzenzakalelayo: Siza imoto ngokuzenzakalelayo ithole indawo efanele yokupaka endaweni yokupaka bese uqedela ukusebenza kokupaka.
Amapharamitha Ezobuchwepheshe Nezimpawu Zokusebenza
Ama-automative microwave radars ajwayele ukusebenza kuma-millimeter wave band, njenge-24ghz, enezikhathi eziphakeme kanye nama-wavelength afushane. Lokhu kwenza i-microwave radar ibe nokuqondiswa okuphezulu nokuxazululwa, futhi kungathola ukunemba okuvuselelayo. Ngaphezu kwalokho, i-radar ye-microwave ayithinteki ngokubonakala futhi ingasebenza ngokujwayelekile ezimweni zezulu ezimbi. Kodwa-ke, izindleko ze-microwave radar ziphakeme kakhulu, futhi amandla okuthola izinto ezincane azilungile njenge-lidar.
Imisebenzi esemqoka ye-Automotive Microwave Radar ifaka phakathi izici ezilandelayo:
Isexwayiso sokuhlangana kanye ne-automatic ephuthumayo Braking (AEB): I-Microwave ARADARS ithola izithiyo ezizayo futhi uma kunesidingo kubangela uhlelo oluzenzakalelayo lokuphuthumayo ukuvikela ukushayisana.
Ukutholwa kwe-Pedestrian: nge-microwave radar, izimoto zingabona futhi zibone abahamba ngezinyawo, ngaleyo ndlela zithuthukise ukuphepha kokushayela.
Ukuqapha I-Blind Spot Readong kanye ne-Lane Space Searcting: I-Microwave Radar ingabheka indawo eyimpumputhe yemoto ukuvikela ukushayisana nezinye izimoto lapho kushintsha imizila, futhi kungaqapha abashayeli be-Lane kanye nabashayeli bokuqwashisa.
I-Adaptive Cruise Control (ACC): I-Microwave Radar ingasiza izimoto zilondoloze ibanga elivikelekile kusuka emotweni phambi kokulawulwa kokuhamba ngezindlela eziguqukayo.
Isexwayiso sethrafikhi engemuva (i-RCTA): I-Microwave Radar ingabheka ithrafikhi ngemuva kwemoto, khumbuza umshayeli ukuthi anake imoto ezayo, ukugwema ukubuyela emuva kokushayisana.
Umgomo osebenzayo we-microwave radar ukukala isikhundla selitshe ngokuthumela amagagasi angenantambo (amagagasi akwaRadar) nokwamukela i-echo ngokuya ngomehluko wesikhathi phakathi kokuthumela nokwamukela. Imvamisa ye-millimeter wave radar ise-millimeter wave band, ngakho-ke ibizwa nge-millimeter wave radar.
Ukusetshenziswa kwamabhande ajwayelekile we-microwave radar ezimotweni kuhlanganisa amabhendi amabili e-24ghtz ne-77ghtz. I-24ghzs radars isetshenziselwa kakhulu ukutholwa kwama-range amafushane, kuyilapho ama-77ghzz adars enesinqumo esiphakeme futhi asayizi omncane, efanelekile ukuthola okutholwa okude.
