Iyo AFS - Active Steering Systems inoshanda sei

Automation, yakashongedzerwa nemaalgorithms eakanakisa mainjiniya epasirese uye vanoedza, yagara ichiziva kutyaira mota zviri nani kupfuura ruzhinji rwevatyairi vadzo. Asi vanhu havasati vagadzirira kuzvivimba zvizere, hutsva huri kuiswa zvishoma nezvishoma, vachichengetedza mikana yekutonga kwebhuku. Zvinenge zvinoenderana neiyi musimboti, iyo AFS inoshanda yekutungamirira drive system inovakwa.

System kushanda algorithm

Chinhu chikuru cheAFS ndiyo inoshanduka yegiya reshiyo. Kuronga kutsamira kweiyi parameter pakumhanya, uye kunyanya pane zvimwe zvinofurira zvinhu, zvakazove zvisiri nyore sezvazvingaita seautomation nyanzvi. Iyo yakaomesesa mechanicha dhiraivha kubva pachidhiraivho kuenda kumavhiri anodhiraivha yaifanira kuchengetedzwa; iyo mota yepasirese yaisazokurumidza kuenderera mberi mukuzadzikiswa kuzere kweiyo control system chete nemawaya emagetsi. Naizvozvo, Bosch akawana patent kubva kuAmerican muvambi, mushure mezvo, pamwe neBMW, yekutanga dhiraivha system yakagadziridzwa, inonzi AFS - Active Front Steering. Nei chaizvo "Front" - kune anoshanda mhando masisitimu anosanganisirawo mavhiri ekumashure.

Nheyo yacho yakapfava, sezvakaita uchenjeri hwose. Kufambisa magetsi kwakashandiswa kwakashandiswa. Asi giya repuraneti rakavakwa muchikamu chegiya rekutungamirira. Yayo giya reshiyo mune inoshanduka modhi inoenderana nekumhanya uye kwakanangana nekutenderera kweiyo yekunze giya ine yemukati giya (korona). Iyo shaft inofambiswa, sekunge, inobata kumusoro kana kusara kumashure kweinotungamira. Uye izvi zvinodzorwa nemota yemagetsi, iyo kuburikidza nenotch padivi rekunze regiya ine worm drive yayo inoita kuti itenderere. Nekumhanya kwakakwana uye torque.

Hunhu hutsva uhwo AFS yakawana

Kune avo vakakwira kuseri kwevhiri reiyo AFS-yakagadzirirwa BMWs, manzwiro ekutanga akatarisana nekutya. Mota yakangoerekana yaita tekisi, ichimanikidza kukanganwa tsika "yekupetera" pachidhiraivho munzira dzekupaka uye kufambisa nekumhanya kwakaderera. Mota yakarongedzerwa patsva mumugwagwa senge kart yemujaho, uye matenderedzwa madiki evhiri, tichichengetedza kureruka, akatimanikidza kuti titarise patsva maitiro ekutendeuka munzvimbo yakamanikana. Kutya kuti motokari ine maitikiro akadaro yaizotadza kutyaira ichimhanya zvikuru kwakakurumidza kupera. Paunenge uchityaira pakufamba kwe150-200 km / h, motokari yakawana kusimba kusingatarisirwi uye kutsvedza, kuchengetedza nyika yakagadzikana zvakanaka uye kwete kuedza kuputsa. Mhedziso dzinotevera dzinogona kuitwa:

  • iyo giya reshiyo yegiya rekutungamirira, painoshandurwa nehafu nekuwedzera kwekumhanya, yakapihwa nyore uye yakachengeteka kutonga mune ese modes;
  • mumamiriro ezvinhu akaipisisa, pamucheto wekutsvedza, motokari yakaratidza kugadzikana kusingatarisirwi, izvo zvakanga zvakajeka kwete nekuda kwekusiyana kwegiya regiyo yegiya rinotungamira;
  • iyo understeer yaigara yakachengetwa iri padanho rakanyatsoenderana, mota yaisada kutsvedza ekisero yekumashure kana kutsvedza ekisero yekumberi;
  • zvishoma zvakatsamira paunyanzvi hwomutyairi, rubatsiro rwemotokari rwainyatsooneka;
  • kunyange kana motokari yacho yaisvetuka nemaune nezviito zvechisimba zvemutyairi ane ruzivo, zvaive nyore kutyaira mairi, uye motokari pachayo yakabuda mairi nokukurumidza apo kutsamwisa kwakamira, uye zvakakwana uye pasina counter-skids.

Iye zvino akawanda ekudzikamisa masisitimu anokwanisa kuita chimwe chinhu chakafanana, asi kwaingova kutanga kwezana ramakore, uye kungotungamira kwaibatanidzwa, pasina braking uye traction vector torques.

Nekuda kweiyo mhedzisiro yeanoshanda taxiing yakaumbwa

Iyo yemagetsi control unit inounganidza ruzivo kubva kune seti ye sensors inotarisisa vhiri, kutungamira kwemota, angular accelerations uye mamwe akawanda ma parameter. Zvinoenderana neyakagadziriswa modhi, haingoshandure giya reshiyo, sezvo yakarongeka zvichienderana nekumhanya, asi inoronga inoshanda inotungamira, ichikanganisa zviito zvemutyairi. Iri ndiro danho rekutanga rakananga kuzvitonga kuzere.

Muchiitiko ichi, kuwirirana pakati pevhiri uye mavhiri kunoramba kusina kuchinja. Kana magetsi akavharwa, artificially kana nekuda kwekusashanda, shaft yemagetsi emagetsi inotenderera nzira yepuraneti inomira uye inomira. Management inoshanduka kuita yakajairwa rack uye pinion michina ine amplifier. Hapana kufambisa newaya, ndiko kuti, kutonga newaya. Chete mapuraneti giya ane controlled mhete giya.

Pakumhanya kwakanyanya, sisitimu yacho yakaita kuti zvikwanise kunyatso gadzirisa uye mushe mota kubva munzira kuenda kune imwe nzira. Mhedzisiro imwechete yakaonekwa senge painotungamira ekisero yekumashure - mavhiri ayo akanyatso kuteedzera epamberi, pasina kutsamwisa oversteer uye skidding. Izvi zvakawanikwa nekushandura otomatiki kona yekutenderera pane ekisi inodzorwa.

Ehe, hurongwa hwakazove hwakaoma kupfuura kutungamira kwechinyakare, asi kwete nezvakawanda. Giya bhokisi repuraneti uye imwe yemagetsi dhiraivha inowedzera zvishoma mutengo, uye mabasa ese akagoverwa komputa uye software. Izvi zvakaita kuti zvikwanise kuita iyo system pane ese akateedzana emota dzeBMW, kubva kune yekutanga kusvika yechinomwe. Iyo mechatronics unit ndeye compact, inoratidzika seyakajairwa magetsi emagetsi, inopa mutyairi manzwiro akafanana emota, inopa mhinduro uye inova intuitive mushure mekukurumidza kujaira kuchinja kupinza kwevhiri.

Kuvimbika kwehurongwa hakuna kunyanya kusiyana nemaitiro echinyakare. Pane kungopfeka zvishoma zvakanyanya kweiyo rack uye pinion nekuda kwekuwedzera kwesimba rekuita. Asi ichi mutengo muduku kubhadhara zvachose itsva unhu motokari mukubata chero kumhanya.
