Isebenza kanjani i-lift assist system

Ukuhamba ngamandla kwedolobha nezindawo zezintaba kudinga ukuqapha okwedlulele ohlangothini lomshayeli, ikakhulukazi emithambekeni. Ngenkathi abashayeli abanolwazi kufanele babaleke kalula, ukubuyela emuva egqumeni kuyimbangela evamile yezingozi. Isixazululo senkinga uhlelo lwe-lift assist, okufanele lunikeze umshwalense wabaqalayo kanye nabashayeli bokuqapha abalahlekile.

Luthini uhlelo lokulekelela ilifti

Abakhiqizi bezimoto banamuhla baqondisa imizamo yabo ephezulu yokwenza ezokuthutha eziphephile ngokwethula izinhlelo ezahlukahlukene zokuphepha ekuklanyeni. Enye yazo uhlelo lokulekelela ilifti. Ingqikithi yayo ukuvikela imoto ukuthi yehle iye phansi lapho umshayeli ededela ibhuleki elixegayo.

Isixazululo esikhulu esaziwayo sithi Ukulawulwa Kokusiza Kwe-Hill-Start (HAC noma HSA). Igcina ingcindezi kumasekethe wamabhuleki ngemuva kokuthi umshayeli esuse unyawo lakhe kuphedali. Lokhu kukuvumela ukuthi unwebe impilo yamapayipi wamabhuleki futhi uvikele ukuqala kokukhuphuka.

Umsebenzi wesistimu wehliselwe ekutholakaleni okuzenzakalelayo kwemithambeka nokusetshenziswa kohlelo lwamabhuleki. Umshayeli akusadingeki ukuthi afake ibhuleki lesandla noma akhathazeke ngokuphepha okungeziwe lapho eshayela ekukhuphukeni.

Inhloso kanye nemisebenzi eyinhloko

Inhloso enkulu ukuvikela imoto ukuthi ibuyele emuva emthambekeni ngemuva kokuqala ukuhamba. Abashayeli abangenalwazi bangakhohlwa ukugibela lapho benyuka umqansa, okwenza imoto iginqike ibheke phansi, mhlawumbe kudale ingozi. Uma sikhuluma ngezici ezisebenzayo ze-HAC, kufanelekile ukugqamisa okulandelayo:

1. Ukunqunywa kwe-engeli yokuthambekela kwemoto - uma inkomba ingaphezulu kuka-5%, uhlelo luqala ukusebenza ngokuzenzekelayo.
2. Ukulawulwa kwamabhuleki - uma imoto ima bese iqala ukuhamba, isistimu igcina ingcindezi emabhulekini ukuqinisekisa ukuqala kahle.
3. Injini RPM Control - Lapho i-torque ifinyelela ezingeni olifunayo, amabhuleki ayadedelwa bese imoto iqala ukuhamba.

Isistimu yenza umsebenzi omuhle kakhulu ezimeni ezijwayelekile, futhi isiza nemoto eqhweni nasezimweni ezingekho emgwaqweni. Inzuzo eyengeziwe ukuvimbela ukubuyela emuva ngaphansi kwamandla adonsela phansi noma emthambekeni omkhulu.

Izici zokuklama

Azikho izinto ezakhiwayo ezidingekayo ukuhlanganisa isixazululo emotweni. Ukusebenza kuqinisekiswa yi-software kanye nomqondo obhaliwe wezenzo zophiko lwe-ABS noma lwe-ESP. Akukho mehluko wangaphandle emotweni ene-HAS.

Umsebenzi wokusiza wokuphakamisa kufanele usebenze kahle noma ngabe imoto ibuyela emuva.

Isimiso nengqondo yomsebenzi

Uhlelo lunquma ngokuzenzakalela i-engeli yethambeka. Uma yeqa u-5%, i-algorithm ezenzekelayo yezenzo iyasungulwa. Lokhu kusebenza ngendlela yokuthi ngemuva kokukhulula isisekelo sebhuleki, Igcine ingcindezi ohlelweni futhi yavimbela ukubuyela emuva. Kunezigaba ezine eziyinhloko zomsebenzi:

• umshayeli ucindezela i-pedal futhi wakha ingcindezi ohlelweni;
• ukubamba ingcindezi usebenzisa imiyalo evela ku-elekthronikhi;
• ukuncipha kancane kancane kwamapayipi amabhuleki;
• ukukhishwa okuphelele kwengcindezi nokuqala kokuhamba.

Ukuqaliswa kokusebenza kohlelo kufana nokusebenza kohlelo lwe-ABS. Ungafunda kabanzi ngalokhu ku-athikili yethu. Lapho umshayeli ecindezela i-pedal brake, ingcindezi iyanda ohlelweni lwamabhuleki bese kufakwa amabhuleki esondo. Isistimu ikhiya ithambeka bese ivala ngokuzenzakalela ama-valve wokufaka nawokukhipha emzimbeni we-ABS valve. Ngakho-ke, ingcindezi esezikhungweni zamabhuleki iyagcinwa futhi uma umshayeli esusa unyawo esigqokweni sebhuleki, imoto izohlala imile.

Ngokuya ngomkhiqizi, isikhathi sokubamba semoto ekuthambekeni singalinganiselwa (cishe imizuzwana emi-2).

Lapho umshayeli ecindezela i-pedal yegesi, uhlelo luqala ukuvula kancane kancane ama-valve wokukhipha emzimbeni we-valve. Ingcindezi iqala ukwehla, kepha isiza ukuvimbela ukwehla. Lapho injini ifinyelela ku-torque elungile, ama-valve avuleka ngokuphelele, ingcindezi iyadedelwa, namaphakethe akhishwe ngokuphelele.

Intuthuko efanayo evela kubakhiqizi abahlukahlukene

Iningi lezinkampani zomhlaba zikhathazekile ngokufaka imikhiqizo emisha ezimotweni nokwandisa ukunethezeka kokushayela. Ngalokhu, konke okwenziwayo okwenzelwe ukuphepha nokusizakala kwabashayeli kuyasizakala. Iphayona ekwakhiweni kwe-HAC kwakunguToyota, ekhombisa umhlaba ukuthi kungenzeka ukuqala emthambekeni ngaphandle kwesinyathelo esengeziwe. Ngemuva kwalokho, uhlelo lwaqala ukuvela nakwabanye abenzi.

I-HAC, i-Hill-Start Assist Control	Toyota
HHC, Hill Bamba Ukulawula	Volkswagen
Hill Umnikazi	Fiat, iSubaru
USS, Usekelo Lokuqala Lokukhuphuka	I-Nissan

Yize lezi zinhlelo zinamagama ahlukile futhi umqondo womsebenzi wazo ungahluka kancane, ingqikithi yesixazululo ibila entweni eyodwa. Ukusetshenziswa kosizo lokuphakamisa kukuvumela ukuthi ukhuphule ijubane lemoto ngaphandle kwesenzo esingadingekile, ngaphandle kokwesaba usongo lokubuyela emuva.
