1.Dab tsi yog Brake-by-Wire (BBW)?
Brake-by-Wire (BBW) yog ib qho kev nce qib hauv kev ua haujlwm ntawm lub braking system uas paub txog tus neeg tsav tsheb lub hom phiaj braking los ntawm sensors.Lub tshuab hluav taws xob tswj (ECU) ces xa cov lus qhia ua tiav rau lub cev muaj zog tsav los muab kev pab cuam braking, ua kom muaj hluav taws xob thiab kev txawj ntse ntawm kev tswj nres.
Muaj ob lub ntsiab kev daws teeb meem rau Brake-By-Wire: Electro-hydraulic Braking System (EHB) thiab Electro-mechanical Braking System (EMB). Ntawm lawv, EHB yog raws li cov hydraulic nres architecture uas twb muaj lawm, tseem hu ua 'ntub nres- by-wire'; EMB tsis muaj hydraulic nres pipeline, tseem hu ua 'dry brake-by-wire'. Txawm li cas los xij, vim kev siv thev naus laus zis thiab cov khoom lag luam kom loj hlob, tsis muaj cov qauv thiab kev cai lij choj, thiab cov nqi pib cov khoom lag luam siab, cov ntawv thov ntau lawm tseem nyob deb.Tam sim no, nres-los ntawm-xaim tseem feem ntau hu ua EHB.
Vim qhov tsis muaj zog ntawm kev pab cuam nres hauv lub zog tshiab, uas yog thawj zaug tso siab rau lub cav cua kom nqus siphon nyhuv, lub cev muaj zog-tsav (lub zog-pab) nres-los ntawm-xaim tau tshwm sim. Qhov no yog qhov tseeb tshwj xeeb tshaj yog rau cov tsheb fais fab uas tsis muaj lub cav.Brake-by-wire tsis tsuas yog ua kom muaj kev nyab xeeb ntawm cov tsheb tshiab lub zog tab sis kuj ua raws li kev nce qib ntawm cov thev naus laus zis no.
Kev tshawb fawb qhia tau hais tias los ntawm lub thib ob ib nrab ntawm 2023, brake-los-wire (EHB) systems yuav siv nyob rau hauv yuav luag tag nrho cov tsheb tshiab nyob rau hauv kev loj hlob los yog ntau lawm. Lub tshuab nqus tsev twj siv hluav taws xob (EVP) system, uas tau tsim los daws qhov teeb meem ntawm lub tshuab nqus tsev tsis txaus lossis tsis muaj lub tshuab nqus tsev, yuav sai sai no. Qhov no txhais tau hais tias feem ntau ntawm lub zog tshiab tsheb yuav tau nruab nrog lub tshuab nres-los-xaim yav tom ntej.Lub sijhawm no, qee lub tsheb siv roj kuj tau nruab nrog lub tshuab nres-los-xaim rau lub hom phiaj ntse, xws li Chery, Tiggo. Cov ntaub ntawv tseem ceeb qhia txog kev kwv yees tias Suav lag luam hauv tsev rau cov tshuab nres-los-xaim yuav tshaj 10 lab units hauv ob peb xyoos tom ntej.
2.Ib 2023,tuskev muag khoom ntawm One-Box tsheb dhau lawmcovntawm Ob-Box tsheb.
EHB tuaj yeem muab faib ua ob hom: discrete (Ob-Box) thiab kev koom ua ke (One-Box), nyob ntawm seb nws puas koom nrog ESC system. Cov tshuaj Ob-Box ua raws li cov qauv ntawm cov tsoos hydraulic nres system, siv lub tshuab hluav taws xob los hloov cov khoom siv hluav taws xob qub. Qhov no ua rau muaj kev hloov pauv tsawg dua rau kev teeb tsa ntawm lub braking system, ua rau nws yooj yim los hloov thiab txhawb nqa. Raws li qhov tshwm sim, nws yog thawj zaug uas tau tsim tawm ntau.
Qhov kev daws teeb meem ob lub thawv tau qhib lub qhov rooj rau kev siv brake-los ntawm-xaim, thiab kev nrawm ntawm kev siv thev naus laus zis thiab kev tsim kho tshiab tsis tau nres. Qhov no tau coj mus rau One-Box kev daws teeb meem, uas sib koom ua ke cov khoom siv hluav taws xob nrog ABS / ESC system.Piv rau ob lub thawv, ib lub thawv muaj qhov zoo ntawm kev sib koom ua ke siab, qhov xav tau ntawm qhov chaw qis, qhov hnyav thiab siab zog rov qab. efficiency. Nws tau qhuas heev los ntawm kev lag luam. Piv txwv li, nrog nws cov khoom lag luam nres-los-xaim, Continental lub teb chaws Yelemees tau txiav txim siab hla ob lub thawv thiab tsom mus rau ib lub thawv daws teeb meem.
Saib ntawm kev ua lag luam nres-los-hlau, txij li xyoo 2022, ib lub thawv tau nrov heev li ob lub thawv. Hauv xyoo 2023, kev muag khoom ntawm ib lub thawv tau dhau los ntawm kev muag khoom ntawm ob lub thawv.Nws tau pom tias yuav luag txhua tus qauv tshiab tsim nyob rau xyoo 2023 tau siv One-Box, raws li kev tshuaj xyuas dav dav ntawm cov phiaj xwm phiaj xwm ntau tshaj kaum nres-los ntawm- xaim system cov neeg muag khoom. Nws cia siab tias qhov muag ntim ntawm One-Box hauv 2024 yuav yog ob npaug ntawm Ob-Box. One-Box tseem yuav "ua txoj hauv kev" hauv EHB kev ua lag luam.
3.Brake-los-wire - Ntau pawg sib tw, thiab thawj zaug sib zog yog tus yeej.
Bosch yog thawj tus tsim lub tsheb tiv thaiv kev xauv lub kaw lus (ABS) hauv xyoo 1978. Nyob rau xyoo 2013, nws tau pib tsim ntau ntawm iBooster hauv lub teb chaws Yelemees thiab tau tsim tawm hauv thaj av Asia-Pacific thaum Lub Yim Hli 2017. Nyob rau hauv 2016, Continental AG mass- tsim nws thawj-tiam nres-los-hlau system, MK C1. Ib yam li ntawd, ZF tau pib ntau lawm ntawm nws cov nres-los ntawm-xaim system (IBC) thaum kawg ntawm 2018.Los ntawm cov tsoos automotive electronic braking systems (ABS / ESC / EPB, thiab lwm yam) rau brake-los-wire systems, thoob ntiaj teb nws pib qhov chaw. Cov neeg loj heev uas sawv cev los ntawm Bosch, Continental AG, ZF, thiab lwm yam yog ib txwm nyob rau hauv pem hauv ntej ntawm braking system technology thiab kev lag luam, thiab tau tuav lub luag haujlwm tseem ceeb hauv kev ua lag luam rau lub sijhawm ntev.
Vim li cas thiab yuav ua li cas cov tuam txhab hauv zos tuaj yeem ntes tau nyob rau hauv kev lag luam hauv online braking systems thiab ua tiav qhov kev vam meej sai sai? Ua ntej, vim muaj kev nce ntxiv hauv cov lag luam ywj pheej OEMs, muaj qhov tsis tau muaj qhov xav tau siab thiab ceev ceev rau hauv cheeb tsam thiab kev hloov pauv ntawm cov khoom tseem ceeb, xws li nres-los-hlau. Thib ob, lub localization ntawm tsoos hluav taws xob braking systems xws li ABS / ESC / EPB kuj tau cog qoob loo muaj feem xyuam rau cov khoom lag luam hauv zos thiab cov txuj ci, tso lub hauv paus tseem ceeb rau kev nce ntawm cov lag luam hauv zos.; Ntxiv rau. Ua tsaug rau qhov muaj koob meej loj ntawm "kev siv hluav taws xob" thiab "kev txawj ntse" hauv tsheb, nres-los ntawm-xaim tshuab, ua lub hauv paus tseem ceeb ntawm kev txuag hluav taws xob thiab kev nyab xeeb, tau dhau los ua lub ntsiab lus kub uas lub lag luam peev tau caum xyoo tsis ntev los no. . Ntawm ib sab, nrog kev pab los ntawm peev, ib tug xov tooj ntawm domestic high-tech "tshiab rog" nrog nres-los ntawm-xaim tshuab tau tshwm sim, xws li Tongyu Automotive Technology, Nason Automotive Electronics, thiab lwm yam., uas coj tus thawj coj. nyob rau hauv realizing lub loj ntau lawm ntawm Ob-Box nyob rau hauv Tuam Tshoj. Ntawm qhov tod tes, tsoos nres tuam txhab uas muag, sawv cev los ntawm Bethel Automobile, Asia Pacific Automobile, thiab lwm yam., thiab lub zos tsheb tuam txhab uas muag, sawv cev los ntawm BYD, Great Wall Motor, thiab lwm yam., muaj kuj tau koom thiab koom tes nrog kev pib ntawm nres-los-xaim, ib qho tseem ceeb ntawm cov khoom siv tsheb.
Qhov txuas ntxiv "chip tsis txaus" hauv tsheb tswj hluav taws xob hauv xyoo tas los no tau ua rau muaj kev tsis txaus rau cov tuam txhab lag luam thoob ntiaj teb, uas kuj tau tsim cov kev lag luam tsis tshua muaj rau cov tuam txhab lag luam hauv Suav teb tau npaj zoo, ntawm cov tuam txhab Wuhu Bethel. kev ua tau zoo yog qhov muag pom tshaj plaws. Lub brake-los-wire system (WCBS) thawj zaug tso tawm los ntawm Wuhu Bethel Automobile tau dhau los ua cov khoom lag luam thawj zaug hauv Suav teb.Jingweida Automotive Technology coj tus thawj coj hauv kev tshawb fawb thiab tsim Tuam Tshoj thawj cov tshuaj raws li cov khoom siv hauv tsev, ua qhov kev daws teeb meem no lwm qhov tseem ceeb ntawm cov khoom lag luam One-Box. Nws tau tshaj tawm tias cov khoom lag luam yuav raug tsim tawm hauv lub quarter thib plaub ntawm 2024.
Lub tsheb nres-los ntawm-xaim system muaj cov yam ntxwv ntawm kev nyab xeeb thiab kev ntseeg siab, kev ua haujlwm siab thiab kev ua lag luam siab. Nws yog ib yam khoom "peb siab".Raws li cov ntaub ntawv tsis tiav, tam sim no tsis muaj tsawg tshaj li 40 lub tuam txhab hauv Suav teb koom nrog kev tshawb fawb thiab kev tsim kho tsheb nres-los ntawm-xaim tshuab, tab sis feem ntau ntawm lawv nyob deb ntawm kev tsim khoom. cov khoom lag luam paub tab lossis muaj peev xwm ntau lawm.
Tseem muaj txoj hauv kev ntev mus los ntawm kev tshawb fawb thiab kev tsim kho tsheb nres-los ntawm-xaim tshuab mus rau qhov loj thiab loj hlob loj. Qhov no yog lub sijhawm keeb kwm rau Tuam Tshoj cov tuam txhab nres tsheb hauv zos, thiab nws tseem yog nyob rau hnub ua ntej ntawm Tuam Tshoj txoj kev lag luam ywj pheej ntawm kev lag luam tsheb.
