EBD brake force distribution system - tsananguro uye musimboti wekushanda

Kurwisa kugovaniswazve kwehuremu hwemotokari pamwe chete nemaekisi, primitive hydraulic zvishandiso zvakamboshandiswa kudzora brake force pane imwe kana maviri axle zvichienderana nekuremerwa kuremerwa. Nekuuya kweakakwira-kumhanya akawanda-channel ABS masisitimu uye zvine chekuita nemidziyo, izvi hazvichadiwi. Icho chikamu cheiyo-anti-lock braking system, iyo ine basa rekudzora kudzvanywa kana iyo yepakati yegiravhiti ichichinja pamwe neaxis yemotokari, inonzi EBD - Electronic Brake Distribution, kureva, chaizvo, yemagetsi brake simba kugovera.

Ndeipi basa reEBD mumotokari

Kugoverwa kwehuremu hwekubata pamwe chete nemaaxles emotokari kunokonzerwa nezvinhu zviviri - static uye simba. Yokutanga inotarirwa nekutakurwa kwemotokari, hazvibviri kuisa chiteshi chegesi, vafambi uye kutakura zvinhu nenzira iyo nzvimbo yavo yehuwandu inopindirana neyemotokari isina chinhu. Uye mumasimba, vheti yekusimudzira yakaipa inowedzerwa kune vector yegiravhiti panguva yebraking, inotungamirirwa perpendicular kune iyo inokwevera. Mhedzisiro inoshandura fungidziro ichipinda munzira munzira. Mavhiri epamberi achawedzerwa zvakare, uye chikamu chehuremu hwekudhonza chinobviswa kubva kumashure.

Kana chiitiko ichi chikafuratirwa mubhureki system, zvino kana kudzvanywa mumasilinda emabhureki emberi uye kumashure maaxles akaenzana, mavhiri ekumashure anogona kuvharira kare kupfuura epamberi. Izvi zvinotungamira kune akati wandei asingafadzi uye ane njodzi zviitiko:

• mushure mekuchinja kuenda pakutsvedza kweaxle yekumashure, mota inorasikirwa nekugadzikana, kuramba kwemavhiri kuenda kune lateral kusimuka kune iyo longitudinal imwe ichagadziriswazve, izvo zvishoma zvinokanganisa zvinogara zviripo zvinotungamira kune lateral kutsvedza kweaxle, iyo ndiko, kusvetuka-svetuka;
• iyo yakazara braking simba ichaderera nekuda kwekuderera kweiyo coefficient ye friction yemashure mavhiri;
• chiyero chekupfeka kwematairi emashure chichawedzera;
• mutyairi achamanikidzwa kurerutsa simba pamapedals kuti arege kupinda mukutsvedza kusingadzoreki, nekudaro achibvisa kudzvanywa kubva kumabhureki epamberi, izvo zvinozowedzera kuderedza kushanda kwebhureki;
• iyo motokari icharasikirwa nekugadzikana kwekutungamira, resonance phenomena inogona kuitika iyo yakaoma zvikuru kudzivirira kunyange kumutyairi ane ruzivo.

Maregulator aimboshandiswa akabhadhara chikamu chechiitiko ichi, asi vakazviita zvisiri izvo uye zvisina kuvimbika. Kuonekwa kweABS system pakutanga kwekutarisa kunobvisa dambudziko, asi chaizvoizvo kuita kwayo hakuna kukwana. Icho chokwadi ndechekuti iyo anti-lock braking system panguva imwe chete inogadzirisa mamwe akawanda mabasa, semuenzaniso, inotarisisa kusaenzana kwemugwagwa pasi pevhiri rimwe nerimwe kana kugovaniswa kwehuremu nekuda kwemasimba ecentrifugal mumakona. Basa rakaoma pamwe nekuwedzera kwekuwedzera uye kugovera uremu kunogona kugumburwa pane akati wandei kupokana. Naizvozvo, zvinodikanwa kupatsanura kurwisa kuchinjika kwehuremu hwekubata mune yakaparadzana yemagetsi sisitimu uchishandisa ma sensors akafanana uye actuators seABS.

Nekudaro, mhedzisiro yebasa reaviri masisitimu ichava mhinduro yemabasa mamwe chete:

• kugadzirisa kutanga kwekuchinja kune kutsvedza;
• kudzvinyirira kugadzirisa zvakasiyana kune mabhureki evhiri;
• kuchengetedza kugadzikana kwekufamba uye kudzora mumamiriro ese ezvinhu pamwe chete negwara uye mamiriro emugwagwa wepamusoro;
• kunonyanyisa kushanda deceleration.

Seti yemidziyo haichinji.

Kuumbwa kwemanode uye zvinhu

EBD inoshandisa:

• vhiri kumhanya sensors;
• ABS valve muviri, kusanganisira hurongwa hwekupinza uye kuburitsa mavharuvhu, pombi ine hydraulic accumulator uye inodzikamisa vanogamuchira;
• yemagetsi control unit, chikamu chechirongwa icho chine EBD oparesheni algorithm.

Iyo purogiramu inosarudza kubva kune yakajairika data kuyerera izvo zvinoenderana zvakananga nehuremu kugovera, uye inoshanda navo, kuburitsa iyo ABS chaiyo block.

Action algorithm

Iyo system sequentially inoongorora mamiriro emota zvinoenderana neiyo ABS data:

• mutsauko mukushanda kwechirongwa cheABS chemashure uye maekisi emberi ari kudzidzwa;
• Sarudzo dzakaitwa dzakagadziridzwa muchimiro chemhando yekutanga yekudzora mavharuvhu ekuburutsa eABS migero;
• kushandura pakati pekuderedza kudzvinyirira kana kubata modes kunoshandisa yakajairwa yekudzivirira kudzivirira algorithms;
• kana zvichidikanwa, kubhadhara kuendeswa kwehuremu kune ekisero yepamberi, sisitimu inogona kushandisa kudzvanywa kwepombi ye hydraulic kuti iwedzere simba riri pamberi pemabhureki, iyo yakachena ABS haina.

Uku kushanda kwakafanana kwemaitiro maviri aya kunobvumira mhinduro chaiyo kune longitudinal deceleration uye kuchinja kwepakati pesimba rinokwevera pasi semugumisiro wekutakura motokari. Chero mamiriro ezvinhu, kukwanisa kwekufambisa kwemavhiri ose mana kuchashandiswa zvizere.

Iyo chete dhizaini yehurongwa inogona kutariswa kushanda kwayo uchishandisa algorithms akafanana uye midziyo seABS, ndiko kuti, kumwe kusakwana padanho razvino rebudiriro. Pane zvikanganiso zvine chekuita nekuoma uye kwakasiyana-siyana kwemamiriro emigwagwa, kunyanya nzvimbo inotsvedza, ivhu rakasununguka uye rakapfava, kutsemuka kweprofile pamwe nekuoma kwemigwagwa. Asi nekuuya kweshanduro itsva, nyaya idzi dziri kugadziriswa zvishoma nezvishoma.
