Ko zvinoomesa chassis (tii simbi, mbariro dzepamusoro, nezvimwewo) zvinobatsira here?
Chokutanga pane zvose, muridzi wekuwedzera kwekusimbisa achashandura kushanda kwemotokari yepakutanga.Nekuti, iyo mota kugadzikana kuita kuri kuburikidza nehurefu hweizvi zvikamu, ukobvu, yekuisa poindi yekuzadzisa.Kuwedzera kusimbiswa kuchachinja maitiro ezvikamu zvepakutanga, zvichiita kuti kuchinja kwekushanda kwemotokari.Mubvunzo wechipiri ndewokuti, kushanda kwemotokari kuchava nani kana kuipa mushure mekuwedzera kwekuwedzera kwekusimudzira?Mhinduro yakajairika ndeyekuti: Inogona kuita zvirinani, inogona kuwedzera.Vanhu vane hunyanzvi vanogona kudzora kuvandudza kwekuita kune imwe nzira iri nani.Semuenzaniso, mumwe wevatinoshanda navo akachinja mota ari ega.Anoziva kuti ndepapi kushaya simba kwemotokari yepakutanga uye anonyatsoziva nzira yekusimbisa nayo.Asi kana usingazivi chikonzero nei uri kuita chinjo, ipapo kazhinji kazhinji unenge uchingoita chinjo, izvo zvinokuvadza zvikuru kupfuura kunaka!Mota dzaunotenga dzakaongororwa mazana ezviuru zvemakiromita kuona kuti hapana njodzi mukushandiswa kwemotokari.Ndizvo zvinoitwa nainjiniya mufekitari yemotokari.Izvo zvikamu zvakagadziridzwa hazvisi kuburikidza nekuita kwakasimba kuyedzwa kwekuita uye kusimba kuyedzwa, mhando haina kuvimbiswa, kana iyo kutyoka uye ikadonha mukushandiswa, zvinounza njodzi yehupenyu kumuridzi.Usafunga kuti ichi chinongova chidimbu chinosimbisa, chakaputsika uye zvikamu zvepakutanga zvemotokari.Zvakambofungidzirwa here kuti chidimbu chinosungirirwa chichaputsika uye chinonamira muvhu, zvichikonzera njodzi yakakomba yemotokari ... Kupfupisa, kugadzirisa kune ngozi uye kushanda kunofanira kuchenjerera.
Naizvozvo, ndiyo yakachengeteka uye yakanakisa sarudzo yekusarudza zvikamu zvekutanga zveZhuomeng (Shanghai) Automobile Co., LTD.Unogamuchirwa kubvunza.
Reversing radar is parking security axiliary device, iyo inoumbwa ne ultrasonic sensor (inowanzozivikanwa se probe), controller uye kuratidza, alarm (nyanga kana buzzer) nezvimwe zvikamu, sezvinoratidzwa mumufananidzo 1. Ultrasonic sensor ndiyo inonyanya kukosha ye yose reversing system.Basa rayo nderekutumira uye kugashira mafungu e ultrasonic.Chimiro chayo chinoratidzwa mumufananidzo 2. Parizvino, iyo inowanzoshandiswa probe inoshanda frequency ye40kHz, 48kHz uye 58kHz matatu marudzi.Kazhinji kutaura, kukwirisa frequency, kunowedzera kunzwisiswa, asi yakachinjika uye yakatwasuka gwara rekuona Angle idiki, saka kazhinji shandisa 40kHz probe.
Astern radar inotora ultrasonic kubva musimboti.Kana mota yaiswa mune reverse giya, reversing radar inopinda otomatiki munzvimbo yekushanda.Pasi pekutonga kwemutongi, iyo probe yakaiswa pane yekumashure bumper inotumira mafungu e ultrasonic uye inogadzira masaini echo paunosangana nezvipingamupinyi.Mushure mekugamuchira masaini echo kubva kune sensor, mutongi anotakura data data, nekudaro kuverenga chinhambwe pakati pemuviri wemotokari uye zvipingamupinyi uye kutonga chinzvimbo chezvipingamupinyi.
Reversing radar circuit composition block diagram sezvakaratidzwa mumufananidzo 3, MCU (MicroprocessorControlUint) kuburikidza neyakarongwa chirongwa dhizaini, kudzora inoenderana yemagetsi analog switch drive transmission circuit, ultrasonic sensors inoshanda.Ultrasonic echo masiginecha anogadziriswa nekugashira kwakakosha, kusefa uye kukwirisa maseketi, uye obva aonekwa negumi zviteshi zveMCU.Paunenge uchigamuchira chiratidzo chechikamu chizere che sensor, sisitimu inowana chinhambwe chiri padyo kuburikidza nealgorithm chaiyo, uye inotyaira buzzer kana kuratidza reketi kuyeuchidza mutyairi yepedyo chipingamupinyi chinhambwe uye azimuth.
Basa guru rekudzoreredza radar system nderekubatsira kupaka, kubuda reverse giya kana kumira kushanda kana hama inofamba ichipfuura imwe kumhanya (kazhinji 5km/h).
[Zano] Ultrasonic wave inoreva ruzha runodarika huwandu hwekunzwa kwevanhu (pamusoro pe20kHz).Iine maitiro ehupamhi hwepamusoro, mutsara wakatwasuka, kutungamira kwakanaka, kuparadzanisa kuduku, kupinda kwakasimba, kunonoka kupararira kwekukurumidza (anenge 340m / s) nezvimwe zvakadaro.Ultrasonic masaisai anofamba kuburikidza neopaque solids uye anogona kupinda pakadzika makumi emamita.Kana iyo ultrasonic inosangana nekusachena kana kupindirana, inoburitsa mafungu anotaridza, ayo anogona kushandiswa kuumba kudzika kwekuona kana kubva, uye nekudaro inogona kugadzirwa kuita inotenderera system.
