Ngaba i-chassis stiffeners (iintsimbi zokubopha, iintsimbi eziphezulu, njl.njl.) ziluncedo?
Okokuqala, umnini wokomeleza okongeziweyo uya kutshintsha ukusebenza kwemoto yokuqala. Ngenxa yokuba, ukusebenza kozinzo lwesithuthi kubude bala macandelo, ubukhulu, indawo yokufakela ukufezekisa. Ukuqiniswa okongeziweyo kuya kutshintsha iimpawu zamacandelo asekuqaleni, okubangelwa utshintsho ekusebenzeni kwesithuthi. Umbuzo wesibini kukuba, ngaba ukusebenza kwesithuthi kuya kuba ngcono okanye kubi kakhulu emva kokongezwa kwee-reinforcers ezongezelelweyo? Impendulo esemgangathweni yile: Inokuba ngcono, inokuba mandundu. Abantu abaqeqeshiweyo banokulawula uphuhliso lwentsebenzo ukuya kwicala elingcono. Umzekelo, omnye woogxa bethu watshintsha imoto yedwa. Uyazi apho ubuthathaka bemoto yokuqala kwaye ngokwemvelo uyazi indlela yokuyomeleza. Kodwa ukuba awusazi isizathu sokuba wenze utshintsho, ngoko ke ixesha elininzi usenza nje utshintsho, nto leyo eya kwenza umonakalo omkhulu kunokulunga! Iimoto ozithengayo zivavanyelwe amakhulu amawaka eekhilomitha ukuqinisekisa ukuba akukho ngozi ekusebenziseni iimoto. Yiloo nto eyenziwa yinjineli kumzi-mveliso weemoto. Amacandelo alungisiweyo angekho ngovavanyo oluqinileyo lokusebenza kunye nokuvavanya ukuqina, umgangatho awuqinisekiswanga, ukuba ukuphuka kunye nokuwa kwinkqubo yokusetyenziswa, kuya kuzisa ingozi yobomi kumnini. Musa ukucinga ukuba le nto yinto nje eyomelezayo, ephukile kunye neengxenye zemoto yokuqala. Ngaba ikhe yaqwalaselwa ukuba isiqwenga sokuxhoma siya kuphuka kwaye sibambeke emhlabeni, sibangele ingozi enkulu yendlela ... Ukushwankathela, ukufakwa kwakhona kuyingozi kwaye ukusebenza kufuneka kulumke.
Ngoko ke, lolona khetho lukhuselekileyo kwaye lungcono ukukhetha iindawo zokuqala zeZhuomeng (Shanghai) Automobile Co., LTD. Wamkelekile ukuba ubuze.
Ukubuyisela i-radar isixhobo sokuncedisa ukhuseleko lokupaka, oluqulunqwe yinzwa ye-ultrasonic (eyaziwa ngokuba yi-probe), isilawuli kunye nomboniso, i-alamu (uphondo okanye i-buzzer) kunye nezinye iindawo, njengoko kuboniswe kuMfanekiso 1. Inzwa ye-ultrasonic iyinxalenye ephambili ye yonke inkqubo yokubuyisela umva. Umsebenzi wayo kukuthumela kunye nokufumana amaza e-ultrasonic. Ukwakhiwa kwayo kuboniswe kuMzobo 2. Okwangoku, i-probe isebenza rhoqo ngokuphindaphindiweyo kwe-40kHz, 48kHz kunye ne-58kHz iintlobo ezintathu. Ngokubanzi, okukhona uphezulu ukwenzeka, kokukhona uvakalelo luphezulu, kodwa umkhombandlela othe tye kunye nothe nkqo we-Engile yokubhaqa incinci, ngoko ke sebenzisa ngokubanzi i-40kHz probe.
I-radar ye-Astern ithatha umgaqo we-ultrasonic range. Xa isithuthi sifakwe kwi-gear reverse, i-radar yokubuyisela ingena ngokuzenzekelayo kwimeko yokusebenza. Ngaphantsi kolawulo lomlawuli, i-probe efakwe kwi-bumper yangasemva ithumela amaza e-ultrasonic kwaye ivelise iimpawu ze-echo xa idibana nemiqobo. Emva kokufumana izibonakaliso ze-echo kwi-sensor, umlawuli uqhuba ukucubungula idatha, ngaloo ndlela ubala umgama phakathi komzimba wesithuthi kunye nemiqobo kunye nokugweba indawo yemiqobo.
Ukubuyisela umva umzobo webhloko yesekethe ye-radar njengoko kuboniswe kumfanekiso wesi-3, i-MCU (i-MicroprocessorControlUint) ngoyilo lwenkqubo ecwangcisiweyo, lawula i-electronic analog switch drive transmission circuit, i-ultrasonic sensors iyasebenza. Iimpawu ze-ultrasonic ze-echo zicutshungulwa ngokufumana okukhethekileyo, ukuhluza kunye nokukhulisa iisekethe, kwaye zichongiwe ngamachweba angama-10 e-MCU. Xa ufumana umqondiso wecandelo elipheleleyo le-sensor, inkqubo ifumana umgama osondeleyo ngokusebenzisa i-algorithm ethile, kwaye iqhube i-buzzer okanye isiphaluka sokubonisa ukukhumbuza umqhubi womqobo osondeleyo kunye ne-azimuth.
Umsebenzi oyintloko wenkqubo ye-radar yokubuyisela umva kukuncedisa ukupaka, ukuphuma kwi-gear reverse okanye ukuyeka ukusebenza xa isantya esihambayo sidlula isantya esithile (ngokuqhelekileyo i-5km / h).
[Ingcebiso] I-ultrasonic wave ibhekisa kumaza omsindo odlula uluhlu lokuva kwabantu (ngaphezulu kwe-20kHz). Uneempawu ze-frequency ephezulu, ukusabalalisa umgca othe ngqo, ukulungelelaniswa okulungileyo, ukuchithwa okuncinci, ukungena okunamandla, isantya esicothayo sokusasaza (malunga ne-340m / s) njalo njalo. Amaza e-Ultrasonic ahamba nge-opaque solids kwaye anokungena kubunzulu bamashumi eemitha. Xa i-ultrasonic idibana nokungcola okanye i-interfaces, iya kuvelisa amaza abonakalisiweyo, angasetyenziselwa ukwenza ukufumanisa ubunzulu okanye ukuhlukana, kwaye ngoko kunokwenziwa kwinkqubo ejikelezayo.
