Steering-By-Wire
Cybertruck siv cov xaim tswj kev sib hloov los hloov cov txheej txheem kev sib hloov tsheb ib txwm muaj, ua rau kev tswj hwm zoo dua. Qhov no kuj yog ib kauj ruam tsim nyog los mus rau hauv high-end ntse tsav tsheb.
Yuav ua li cas yog ib tug steer-by-wire system? Yooj yim muab tso, lub kauj-los ntawm-xaim tag nrho tshem tawm qhov kev sib txuas ntawm lub cev ntawm lub kauj thiab lub log thiab siv cov teeb liab hluav taws xob los tswj lub kauj tsheb.
Lub steer-by-wire system tsis tau tsuas yog muaj tag nrho cov zoo ntawm cov tsoos mechanical steering system tab sis kuj muaj peev xwm ua tau angular kis tus yam ntxwv uas nyuaj rau ua tiav nrog txhua yam tshuab Optimization.
Lub steer-by-wire system tsis yog lub tshuab tshiab. Ntau yam OEMs tau tsim cov thev naus laus zis no ntev dhau los, suav nrog Toyota, Volkswagen, Great Phab Ntsa, BYD, NIO, thiab lwm yam, nrog rau lub ntiaj teb nto moo Tier 1 Bosch, Continental, thiab ZF tab tom tsim thiab siv steer-by-wire. systems, tab sis tsuas yog Tesla's Cybertruck tau muab tso rau hauv kev tsim khoom loj hauv qhov tseeb.
Yog li ntawd, qhov kev ua tau zoo tom ntej ntawm Cybertruck yog qhov ua lag luam zoo heev. Nyob rau tib lub sijhawm, cov thev naus laus zis no tseem yog cov thev naus laus zis tseem ceeb ntawm "sliding chassis", yog li nws cov txheej txheem batch tom ntej yog qhov tseem ceeb heev.
Txawm hais tias steer-by-wire thev naus laus zis tuaj yeem tshem tawm qhov qub bulkier kis tau tus mob piv rau cov cuab yeej siv niaj hnub thiab tuaj yeem ua rau lub tsheb sib zog (lub teeb txhais tau tias tsis tshua muaj nqi thiab kev ua siab ntev) thiab tus nqi qis, hluav taws xob xa hluav taws xob tswj tau los ntawm cov teeb liab. Yog hais tias ib yam dab tsi mus tsis ncaj ncees lawm, qhov tshwm sim yuav loj heev. Yog li ntawd, thaum cov thev naus laus zis no tau siv thawj zaug hauv dav hlau dav hlau, nws tau txais kev tsim kho ob npaug rau kev pov hwm ob npaug.
Steer-by-wire technology yog tam sim no dav siv nyob rau hauv tsheb, feem ntau nyob rau hauv rear-log tsav, thiab yog tsis tshua muaj siv nyob rau hauv pem hauv ntej-log tsav. Qhov laj thawj tseem ceeb yog tias cov thev naus laus zis no tsis tuaj yeem muaj teeb meem, thiab cov teeb liab hluav taws xob tsis ua haujlwm tuaj yeem tshwm sim los ntawm ntau yam, xws li roj teeb hluav taws xob hluav taws xob, lub teeb liab qeeb, thiab lwm yam.
Txhawm rau tiv thaiv lub roj teeb los ntawm kev khiav tawm ntawm lub zog tam sim ntawd, Cybertruck tsis tsuas yog siv 48V roj teeb los ua lub zog rau lub cev muaj zog ntawm sab laug ntawm daim duab hauv qab no tab sis kuj txuas rau lub zog hluav taws xob siab. Kuj tseem muaj 2 lub roj teeb thaub qab los xyuas kom meej tias lub roj teeb tsis siv hluav taws xob, thiab nws tseem yog ob qho kev tsim kho dua tshiab.
Cybertruck's steer-by-wire system siv ob lub cev muaj zog, txhua qhov muaj peev xwm ua tau kwv yees li 50-60% ntawm qhov siab tshaj plaws torque thaum lub sijhawm nres tsheb qis. Yog tias ib qho ua tsis tau, tseem muaj ib lub cev muaj zog los muab kev rov ua dua. Tib lub cev muaj zog (tsuas yog ib qho) yog siv los tsav lub kauj tsheb tom qab. Lub cev muaj zog no tuaj yeem ua rau tus neeg tsav tsheb xav txog kev tawm tswv yim simulated., qhov kev tawm tswv yim no tseem ceeb heev. Yog tsis muaj cov lus qhia no, tus neeg tsav tsheb tsis tshua muaj peev xwm pom tau lub kauj ntawm lub log. qhov xwm txheej, thiab nws tseem tuaj yeem xa cov log tsheb thiab cov ntaub ntawv hauv av mus rau chav soj ntsuam kom muab kev tsav tsheb zoo dua. Piv txwv li, thaum koj tig qhov kev taw qhia, nws tuaj yeem tswj tau qhov zoo tshaj plaws tuav ntawm lub log tsheb thiab hauv av.
Txij li cov teeb liab hluav taws xob tau hloov cov kev tswj hwm ib txwm muaj, qhov ua tau zoo thiab lub sijhawm ntawm cov teeb liab kis tau tus mob tseem ceeb heev. Cybertruc siv Ethernet kev sib txuas lus los hloov kev sib txuas lus CAN ib txwm muaj. Nws muaj Gigabit Ethernet system txav cov ntaub ntawv, uas tuaj yeem ua tau raws li cov kev xav tau ntawm kev sib txuas lus siab, cov ntaub ntawv network muaj latency ntawm tsuas yog ib nrab millisecond, ua rau nws zoo tagnrho rau cov teeb liab tig, thiab nws kuj muab cov bandwidth txaus kom tso cai rau ntau yam tswj. sib txuas lus hauv lub sijhawm tiag tiag.
Ethernet muaj bandwidth siab dua li CAN kev sib txuas lus. Tag nrho lub tsheb tuaj yeem faib cov saw daisy. Siv POE thev naus laus zis, Ethernet interface tuaj yeem siv ncaj qha yam tsis muaj kev sib cais ntawm cov khoom siv hluav taws xob tsawg, uas tuaj yeem txo tus nqi ntawm cov hlua hluav taws xob zoo heev. Cov thev naus laus zis no tseem yuav ua lag luam sai thiab siv nrog kev lag luam sai thiab kev siv hauv tsheb Ethernet thiab kev tsav tsheb ntse yav tom ntej.
Cov ntsiab lus:
Txawm hais tias lub kauj-los ntawm-xaim thev naus laus zis tsis yog qib siab heev, nws tau siv rau hauv cov khoom siv ntawm cov tsheb. Yam tsawg kawg ntawm Lexus yav dhau los tau ntsib ntau yam teeb meem thaum nws sim ntes crabs.
Hom kev tshem tawm ncaj qha ntawm cov tsoos sensor mechanical tswj los ntawm cov teeb liab hluav taws xob, txawm hais tias nws yog qhov zoo thiab tus nqi qis, tseem tuaj yeem tso cai rau cov neeg tsav tsheb kom muaj kev tsav tsheb zoo dua, tab sis qhov tseem ceeb tshaj plaws rau cov tsheb yog kev nyab xeeb. Muaj ntau theem ntawm kev ua tsis tiav hauv cov teeb liab hluav taws xob.
Kev txhawb nqa thev naus laus zis yuav tsum tau tshawb xyuas kev lag luam thiab siv sijhawm. Yog tias cov cuab yeej no tau nrov heev yav tom ntej, Yog tias nws ruaj khov, kev siv thev naus laus zis ntawm "hluav taws xob skateboard" yuav raug txhim kho ntxiv.
