Uhlelo lokusabalalisa amandla e-EBD - incazelo kanye nomgomo wokusebenza

Ukuze kuliwe nokusatshalaliswa kabusha okuguquguqukayo kwesisindo semoto ngokuhambisana nama-ekseli, ama-hydraulic asendulo asetshenziswa ngaphambilini ukulawula amandla amabhuleki ku-ekseli eyodwa noma amabili kuye ngomthwalo wokumiswa. Ngokufika kwezinhlelo ze-ABS zamashaneli amaningi anesivinini esiphezulu kanye nemishini ehlobene, lokhu akusadingeki. Ingxenye ye-anti-lock braking system, ebhekele ukulawula ingcindezi lapho i-centre of gravity ishintsha eduze kwe-eksisi yemoto, ibizwa nge-EBD - Electronic Brake Distribution, okusho ukuthi, ngokwezwi nezwi, ukusatshalaliswa kwe-electronic brake force.

Ithini indima ye-EBD emotweni

Ukusatshalaliswa kwesisindo sokubambelela kuma-ekseli emoto kuthonywa yizici ezimbili - ezimile neziguquguqukayo. Okokuqala kunqunywa ukulayishwa kwemoto, akunakwenzeka ukubeka igalaji likaphethiloli, abagibeli kanye nempahla ngendlela yokuthi isikhungo sabo sobuningi sihambisane nemoto engenalutho. Futhi kuma-dynamics, i-vector of acceleration negative yengezwa ku-vector of gravity ngesikhathi sokubhuleka, eqondiswe nge-perpendicular kuleyo yamandla adonsela phansi. Umphumela uzogudluzela i-projection emgwaqeni osendleleni. Amasondo angaphambili azolayishwa ngokungeziwe, futhi ingxenye yesisindo sokudonsa izosuswa ngemuva.

Uma lesi simo singanakwa ohlelweni lwamabhuleki, khona-ke uma ingcindezi kumasilinda amabhuleki e-axle yangaphambili nangemuva ilingana, amasondo angemuva angavimba ngaphambili kakhulu kunangaphambili. Lokhu kuzoholela ezintweni eziningi ezingemnandi neziyingozi:

• ngemuva kokuguqukela ekusheleleni kwe-asi yangemuva, imoto izolahlekelwa ukuzinza, ukumelana kwamasondo ekugudlukeni kwe-lateral okuhlobene ne-longitudinal kuzosethwa kabusha, imithelela emincane ehlala ikhona izoholela ekusheleleni kwe-axle engemuva, lokho kungukuthi, ukugxuma;
• amandla okubhuleka aphelele azokwehla ngenxa yokuncipha kwe-coefficient of friction yamasondo angemuva;
• izinga lokuguga kwamasondo angemuva lizokhula;
• umshayeli uzophoqeleka ukuthi anciphise amandla kuma-pedals ukuze agweme ukungena esiliphuni esingalawuleki, ngaleyo ndlela ehlise ingcindezi yamabhuleki angaphambili, okuzophinde kunciphise ukusebenza kahle kwamabhuleki;
• imoto izolahlekelwa ukuzinza kokuqondisa, izenzakalo ze-resonance zingase zenzeke okunzima kakhulu ukuzibamba ngisho nakumshayeli onolwazi.

Izilawuli ebezisetshenziswa ngaphambilini zanxeshezelwa kancane ngalo mphumela, kodwa zikwenze ngendlela engalungile futhi engathembekile. Ukubonakala kwesistimu ye-ABS ekuboneni kuqala kuqeda inkinga, kodwa empeleni isenzo sayo akwanele. Iqiniso liwukuthi i-anti-lock braking system ixazulula ngesikhathi esisodwa eminye imisebenzi eminingi, isibonelo, iqapha ukungalingani komgwaqo ngaphansi kwesondo ngalinye noma ukusabalalisa kabusha isisindo ngenxa yamandla e-centrifugal emakhoneni. Umsebenzi oyinkimbinkimbi nokwengezwa kokunye nokwabiwa kabusha kwesisindo kungakhubeka ezintweni eziningi eziphikisanayo. Ngakho-ke, kubalulekile ukuhlukanisa ukulwa nokushintsha isisindo sokubamba ohlelweni oluhlukile lwe-elekthronikhi usebenzisa izinzwa ezifanayo kanye nama-actuator njenge-ABS.

Kodwa-ke, umphumela wokuphela komsebenzi wazo zombili izinhlelo kuzoba yisixazululo semisebenzi efanayo:

• ukulungisa isiqalo soshintsho ekusheleleni;
• ukulungiswa kwengcindezi ngokwehlukana kwamabhuleki amasondo;
• ukugcina ukuzinza kokunyakaza nokulawula kuzo zonke izimo eduze kwe-trajectory kanye nesimo somgwaqo;
• deceleration esiphezulu ngempumelelo.

Isethi yemishini ayishintshi.

Ukwakheka kwama-node nezakhi

Ukuze usebenze i-EBD isetshenziswa:

• izinzwa zejubane lesondo;
• Umzimba we-valve ye-ABS, okuhlanganisa uhlelo lwama-valve okungenisa nokukhipha, iphampu ene-accumulator ye-hydraulic kanye nabamukeli abazinzile;
• iyunithi yokulawula ye-elekthronikhi, ingxenye yohlelo oluqukethe i-algorithm yokusebenza ye-EBD.

Uhlelo lukhetha kusuka ekugelezeni kwedatha okujwayelekile lezo ezincike ngqo ekusatshalalisweni kwesisindo, futhi lusebenza nabo, bethula i-block ye-ABS ebonakalayo.

I-algorithm yesenzo

Uhlelo luhlola ngokulandelana isimo semoto ngokuya ngedatha ye-ABS:

• umehluko ekusebenzeni kohlelo lwe-ABS lwama-axles angemuva nangaphambili uyafundwa;
• izinqumo ezenziwe zisemthethweni ngendlela yokuguquguquka kokuqala kokulawula ama-valve okukhipha iziteshi ze-ABS;
• ukushintsha phakathi kokunciphisa ingcindezi noma izindlela zokubamba kusebenzisa izindlela ezijwayelekile zokuvimbela ukuvimbela;
• uma kunesidingo, ukunxephezela ukudluliswa kwesisindo ku-axle yangaphambili, uhlelo lungasebenzisa ukucindezela kwepompo ye-hydraulic ukwandisa amandla kumabhuleki angaphambili, okuyinto i-ABS ehlanzekile engenzi.

Lokhu kusebenza okufanayo kwalezi zinhlelo ezimbili kuvumela ukusabela okunembile ekuncipheni kwe-longitudinal kanye nokugudluzwa kwesikhungo se-gravity ngenxa yokulayisha imoto. Kunoma isiphi isimo, amandla okudonsa awo womane amasondo azosetshenziswa ngokugcwele.

Okuwukuphela kwe-drawback yesistimu kungabhekwa njengokusebenza kwayo kusetshenziswa ama-algorithms nemishini efanayo ne-ABS, okungukuthi, ukungapheleli okuthile ezingeni lamanje lentuthuko. Kukhona ukushiyeka okuhambisana nobunkimbinkimbi kanye nezinhlobonhlobo zezimo zomgwaqo, ikakhulukazi izindawo ezishelelayo, inhlabathi evulekile futhi ethambile, ukuphuka kwephrofayili kuhlanganiswe nezimo zomgwaqo ezinzima. Kodwa ngokufika kwezinguqulo ezintsha, lezi zinkinga ziyaxazululwa kancane kancane.
