Zvinosimbisa chassis (tie bars, top bars, nezvimwewo) zvinobatsira here?
Chekutanga, muridzi wekuwedzera simba rekusimbisa mota achachinja mashandiro emota yekutanga. Nekuti, kushanda kwemotokari kunoenderana nehurefu hwezvinhu izvi, ukobvu, uye nzvimbo yekuisa. Kuwedzera simba rekusimbisa mota kuchachinja hunhu hwezvikamu zvepakutanga, zvichikonzera shanduko mukushanda kwemota. Mubvunzo wechipiri ndewekuti, kushanda kwemota kuchave nani here kana kuipa mushure mekuwedzera mamwe mareinforcer? Mhinduro yakajairika ndeyekuti: Inogona kuva nani, inogona kuipa. Vanhu vane hunyanzvi vanogona kudzora kufambira mberi kwekushanda kwayo kuenda kune imwe nzira iri nani. Semuenzaniso, mumwe wevashandi vedu akachinja mota ari ega. Anoziva pane kusasimba kwemota yekutanga uye anoziva nzira yekuisimbisa. Asi kana usingazive kuti sei uri kuita shanduko, saka kazhinji unenge uchingoita shanduko, izvo zvinokuvadza kupfuura zvakanaka! Mota dzaunotenga dzakaedzwa kwemazana ezviuru zvemakiromita kuti ive nechokwadi chekuti hapana njodzi mukushandiswa kwemota. Ndizvo zvinoitwa nemainjiniya mufekitori yemota. Zvikamu zvakagadziriswa hazviitwi nekuyedzwa kwakasimba kwekushanda uye kuyedzwa kwekugara kwenguva refu, mhando yacho haina vimbiso, kana zvikatyoka uye zvikadonha panguva yekushandiswa, zvichaunza njodzi kumuridzi. Usafunge kuti ichi ingori chidimbu chinosimbisa, chakatyoka uye zvikamu zvemotokari yekutanga. Zvakambofungidzirwa here kuti chidimbu chinosungirirwa chichatyoka chonamira muvhu, zvichikonzera tsaona yemotokari... Muchidimbu, kugadzirisazve kune njodzi uye kushanda kunofanira kungwarira.
Saka, ndiyo sarudzo yakachengeteka uye yakanakisisa kusarudza zvikamu zvepakutanga zveZhuomeng (Shanghai) Automobile Co., LTD. Munobvumirwa kubvunza.
Radar yekudzosera kumashure mudziyo wekuchengetedza wekupaka, unoumbwa ne sensor ye ultrasonic (inozivikanwa se probe), controller ne display, alarm (horn kana buzzer) nezvimwe zvikamu, sezvakaratidzwa muMufananidzo 1. Ultrasonic sensor ndiyo chikamu chikuru che reverser system yese. Basa rayo nderekutumira nekugamuchira mafungu e ultrasonic. Maumbirwo ayo anoratidzwa muMufananidzo 2. Parizvino, probe inoshandiswa kazhinji ye40kHz, 48kHz uye 58kHz mhando nhatu. Kazhinji, kana frequency yakakwira, kunzwa kwakakwira, asi nzira yakatwasuka uye yakatwasuka yekuona Angle idiki, saka kazhinji shandisa probe ye40kHz.
Radar yeAstern inoshandisa nzira yekushandura mafambiro emota. Kana mota ikaiswa mugiya rekumashure, radar yekudzosera kumashure inopinda otomatiki mumamiriro ekushanda. Pasi pekutungamirirwa kwemutongi, probe yakaiswa pabhampa rekumashure inotumira mafungu eultrasonic uye inogadzira masaini e echo kana yasangana nezvipingamupinyi. Mushure mekugamuchira masaini e echo kubva ku sensor, mutongi anoita basa rekugadzirisa data, nokudaro achiverenga daro riri pakati pemuviri wemotokari nezvipingamupinyi uye achitonga nzvimbo yezvipingamupinyi.
Kudzosera dhayagiramu ye radar circuit composition block sezvakaratidzwa pamufananidzo 3, MCU (MicroprocessorControlUint) kuburikidza nehurongwa hwepurogiramu yakarongwa, kudzora circuit yemagetsi yeanalog switch drive inoenderana, ma ultrasonic sensors anoshanda. Ma ultrasound echo signals anogadziriswa ne special receiving, filtering uye amplifier circuits, uye ozoonekwa nema ports gumi eMCU. Pakugamuchira chiratidzo chechikamu chose che sensor, system inowana daro riri pedyo kuburikidza ne algorithm chaiyo, uye inotyaira buzzer kana display circuit kuti iyeuchidze mutyairi nezve daro riri pedyo nechipingamupinyi uye azimuth.
Basa guru re reverse radar system nderekubatsira kupaka mota, kubuda mu reverse gear kana kumira kushanda kana kumhanya kwemota kuchidarika kumhanya kwakati (kazhinji 5km/awa).
[Zano] Mafungu eUltrasonic anoreva mafungu eruzha anodarika nhanho yekunzwa kwevanhu (inopfuura 20kHz). Ane hunhu hwemafrequency akakwira, kupararira kwemutsetse wakatwasuka, kutungamira kwakanaka, diffraction diki, kupinda kwakasimba, kumhanya kwekupararira kunononoka (inenge 340m/s) nezvimwewo. Mafungu eUltrasonic anofamba nepakati pezvinhu zvakaoma zvisingaonekwe uye anogona kupinda kusvika pakadzika kwemamita makumi. Kana ultrasonic ikasangana netsvina kana ma interfaces, inoburitsa mafungu anoratidzwa, ayo anogona kushandiswa kugadzira kuona kudzika kana kutenderera, uye nekudaro anogona kugadzirwa kuita sisitimu yekutenderera.
