Ingabe iziqinisi ze-chassis (izinti zokubopha, izinti eziphezulu, njll.) ziwusizo?
Okokuqala, umnikazi wokuqinisa okwengeziwe uzoshintsha ukusebenza kwemoto yokuqala. Ngoba, ukusebenza kokuqina kwemoto kuncike kubude balezi zingxenye, ubukhulu, iphuzu lokufaka okufanele lifinyelelwe. Ukuqinisa okwengeziwe kuzoshintsha izici zezingxenye zokuqala, okuholela ekushintsheni kokusebenza kwemoto. Umbuzo wesibili uwukuthi, ingabe ukusebenza kwemoto kuzoba ngcono noma kubi ngemva kokwengezwa kweziqinisekisi ezengeziwe? Impendulo ejwayelekile ithi: Kungaba ngcono, kungaba kubi kakhulu. Abantu abangochwepheshe bangalawula ukuthuthukiswa kokusebenza kube yindlela engcono. Isibonelo, omunye wozakwethu ushintshe imoto ngokwakhe. Uyazi ukuthi ubuthakathaka bemoto yokuqala bukuphi futhi ngokwemvelo uyazi ukuthi angabuqinisa kanjani. Kodwa uma ungazi ukuthi kungani wenza izinguquko, khona-ke isikhathi esiningi wenza izinguquko nje, okuzokwenza umonakalo omkhulu kunokuhle! Izimoto ozithengayo zihlolwe amakhulu ezinkulungwane zamakhilomitha ukuqinisekisa ukuthi akukho ngozi ekusetshenzisweni kwezimoto. Yilokho okwenziwa unjiniyela efektri yezimoto. Izingxenye eziguquliwe azikho ngokuhlolwa kokusebenza okuqinile kanye nokuhlolwa kokuqina, ikhwalithi ayiqinisekisiwe, uma ukuphuka nokuwa ngesikhathi sokusetshenziswa, kuzoletha ingozi empilweni yomnikazi. Ungacabangi ukuthi lokhu kumane kuyisici esiqinisayo, esiphukile futhi izingxenye zemoto yokuqala. Ingabe kwake kwacatshangwa ukuthi ingxenye yokufaka izophuka futhi ibhajwe phansi, okubangela ingozi enkulu yemoto... Ngamafuphi, ukuphinda ufake kabusha kuyingozi futhi ukusebenza kufanele kuqaphe.
Ngakho-ke, kuyindlela ephephile nengcono kakhulu yokukhetha izingxenye zokuqala zeZhuomeng (Shanghai) Automobile Co., LTD. Wamukelekile ukubuza.
I-radar yokubuyisela emuva iyithuluzi elisizayo lokuphepha lokupaka, elenziwe nge-sensor ye-ultrasonic (eyaziwa kakhulu ngokuthi i-probe), isilawuli kanye nesibonisi, i-alamu (uphondo noma i-buzzer) nezinye izingxenye, njengoba kuboniswe kuMfanekiso 1. I-sensor ye-Ultrasonic iyisici esiyinhloko sohlelo lonke lokubuyisela emuva. Umsebenzi wayo ukuthumela nokwamukela amagagasi e-ultrasonic. Isakhiwo sayo siboniswe kuMfanekiso 2. Njengamanje, imvamisa yokusebenza ye-probe esetshenziswa kakhulu engu-40kHz, 48kHz kanye no-58kHz izinhlobo ezintathu. Ngokuvamile, uma imvamisa iphakeme, kulapho ukuzwela kuphakeme khona, kodwa isiqondiso esivundlile nesiqondile sokutholwa kwe-Angle sincane, ngakho-ke ngokuvamile sebenzisa i-probe engu-40kHz
I-Astern radar isebenzisa isimiso sokuhlela i-ultrasonic. Uma imoto ifakwa egiyeni elibuyela emuva, i-reverse radar ingena ngokuzenzakalelayo esimweni sokusebenza. Ngaphansi kokulawulwa yisilawuli, i-probe efakwe kubhampa yangemuva ithumela amaza e-ultrasonic futhi ikhiqize amasignali e-echo lapho ihlangabezana nezithiyo. Ngemva kokuthola amasignali e-echo avela ku-sensor, isilawuli senza ukucubungula idatha, ngaleyo ndlela sibala ibanga phakathi komzimba wemoto nezithiyo futhi sahlulele indawo yezithiyo.
Ukuguqula umdwebo webhulokhi lokwakheka kwesekethe yeradar njengoba kuboniswe kumfanekiso 3, i-MCU (MicroprocessorControlUint) ngomklamo wohlelo oluhleliwe, lawula isekethe yokudlulisa i-analog switch drive ehambisanayo, izinzwa ze-ultrasonic ziyasebenza. Izimpawu ze-Ultrasonic echo zicutshungulwa ngokwamukela okukhethekile, ukuhlunga nokukhulisa amasekethe, bese kutholwa ngamachweba ayi-10 e-MCU. Lapho kwamukelwa isignali yengxenye ephelele yenzwa, uhlelo luthola ibanga eliseduze nge-algorithm ethile, bese lushayela isekethe ye-buzzer noma yokubonisa ukukhumbuza umshayeli ngebanga eliseduze lesithiyo kanye ne-azimuth.
Umsebenzi oyinhloko wesistimu ye-radar yokubuyela emuva ukusiza ukupaka, ukuphuma kugiya elibuyela emuva noma ukuyeka ukusebenza lapho isivinini sokuhamba sidlula isivinini esithile (ngokuvamile u-5km/h).
[Icebiso] Igagasi le-Ultrasonic libhekisela kugagasi lomsindo elidlula ububanzi bokuzwa kwabantu (ngaphezu kuka-20kHz). Linezici zokuvama okuphezulu, ukusabalala komugqa oqondile, ukuqondiswa okuhle, ukusabalala okuncane, ukungena okunamandla, isivinini sokusabalala esihamba kancane (cishe ama-340m/s) njalo njalo. Amagagasi e-Ultrasonic ahamba ngezinto eziqinile ezingacacile futhi angangena afinyelele ekujuleni kwamamitha angamashumi. Lapho i-ultrasonic ihlangana nokungcola noma izixhumanisi, izokhiqiza amagagasi abonakalisiwe, angasetshenziswa ukwakha ukutholwa kokujula noma ukujikeleza, futhi ngaleyo ndlela angenziwa abe uhlelo lokujikeleza.
