Immobilizers - yog dab tsi? Lub Immobiliser unit. Qhov twg yog qhov Immobiliser

Pib tiv thaiv ntawm lub tsheb tiv thaiv tub sab tub nyiag yuav ua tau tiav los ntawm lub xub ntiag ntawm ntau pab kiag li lawm uas txawv cov hom phiaj, thaum lawv koom los ntawm ib tug tshaj plaws - ruaj ntseg complex. Ib tug ntawm cov tseem ceeb nyob rau hauv cov ntaub ntawv no yog immobilizers. Hais tias yog, nws yuav muaj tseeb ntawm qhov nram qab no piav qhia txog.

lub sij hawm

Lub tsheb ruaj ntseg complex muaj xws li ib tug cov neeg kho tshuab txhais tau tias kev tiv thaiv, tswb, Immobiliser thiab neeg ua hauj lwm ib tug txhais tau ceeb toom rau tus tswv ntawm lub tshuab. Feem ntau cov feem ntau, tus tiv thaiv zog ntawm lub tswb nws yuav siv sij hawm. Tab sis tsis yog lub xeem lub luag hauj lwm nyob rau hauv no reserved Immobiliser. Yog hais tias koj xav muab txoj kev feem ntau txhim khu kev qha kev tiv thaiv tiv thaiv tsis tau tso cai siv, nws yog tsim nyog rau nruab ob peb kev ruaj ntseg pab kiag li lawm, ywj siab ntawm txhua lwm yam.

Yog li ntawd, cia saib immobilisers. Yuav ua li cas hom ntawm pab kiag li lawm, nws yuav ntshiab, yog hais tias peb xav tias lawv khiav hauj lwm hauv paus ntsiab lus. Cov tau mus qhib thiab deactivate xws li yuav tsum tsuas yog ib tug neeg uas yog tus tswv ntawm lub tsheb. Rau cov hom phiaj, siv tseem ceeb Immobiliser. Qauv yog muaj uas pab txhawb qhov kev tuav code nkag teb chaws, tab sis lawv cov loj heev yog tsis yog li ntawd zoo kawg thiab. Cov hluav taws xob tseem ceeb code yog tua nyob rau hauv daim ntawv ntawm ib tug nti thaum lub sij hawm siv thiab tshwj xeeb cipher twb nkag tau rau hauv nws, uas yog ntev txaus tias qhov attacker yuav tsis tos nws nyob rau hauv ib tug luv luv lub sij hawm ntawm lub sij hawm. Lub nti yog nyob rau hauv ib tug yooj yim pob. Pib lub cav ntawm lub tsheb yuav tsum muaj xwb thaum tus tswv ntawm lub ntaus ntawv yuav ntxig mus rau hauv lub qhov muab nyob rau hauv thiaj li yuav deactivate lub Immobiliser. Yog hais tias lub system ua hauj lwm nrog ib phau ntawv tswv yim tseem ceeb, disabling nws tsuas yog tau tom qab nkag mus rau ib theem ntawm cov cim tseg los ntawm tus tswv tsev.

hauv paus ntsiab lus ntawm cov lag luam

Teb cov lus nug: "Immobilizers - yog dab tsi?", Nws yog ib nqi sau cia hais tias lub hauv paus ntsiab lus ntawm lawv cov chaw ua hauj lwm tsis tau hloov nyob rau hauv xyoo tsis ntev los. Ntawm no peb yuav tham txog cov kev kuaj pom ntawm ib tug discontinuity nyob rau hauv lub hluav taws xob circuits uas tseem ceeb heev rau cov ua hauj lwm ntawm lub cav, thiab tus yawm sij uas nws muaj, yog muaj peev xwm los mus tshem tawm no kis. Tsis ntev los no, txawm li cas los, electronics heev tshaj rau pem hauv ntej, ua tau ua tej yam kev kho me ntsis rau cov lag luam ntawm lub ntaus ntawv.

Yog li ntawd, peb tseem mus nrog ib tug lub sij hawm xws li immobilizers. Hais tias nws yuav ua ntau meej yog hais tias peb xav txog lawv ntaus ntawv.

Nrog microprocessor ua tseem ceeb authentication, tom qab uas kaw yuav siv sij hawm qhov chaw tseem ceeb circuits. Nyob rau hauv tas li ntawd, lub tuam txhab koom nyob rau hauv cov obezdvizhivateley ntxiv muaj ib tug ntau ntawm pab kiag li lawm uas ua rau kom cov cia siab rau ntawm lawv ua hauj lwm. Qhov no tej zaum yuav kaw relay thiab roj electromagnetic li qub.

Yuav ua li cas yog nws tsim?

Immobiliser yog tsim los tiv thaiv kom txhob tub sab tub nyiag, txawm tias lub tsheb yog twb qhib. Nyob rau hauv qhov chaw ntawm cov kis ntawm lub cev muaj zog hluav taws xob Circuit Court txheej kaw relay, li ntawd, lub microprocessor cov tshev mis lub authenticity ntawm tus yuam sij, thiab ces txuas ib cov saw ntawm nws tus kheej, tiam sis tsuas yog xa ib lub teeb liab mus rau lub yuav tsum tau electromagnetic keyboards. Tsuas yog ces lawv muaj nyob rau hauv lub kaw hom. Immobiliser yuav txawm ntau txhim khu kev qha tsuas yog los ntawm kev siv ntawm tej relays.

Yog hais tias peb tham txog cov roj valve, nws tsuas muab kaw cov roj kab. Nws yog kaw nyob rau hauv lub dawb lub xeev, yog li lub petrol tank tsis nkag mus rau hauv lub pub system ntawm lub tsheb. Tab sis tom qab tus me nyuam ntawm qhov tseeb lo lus zais, lub microprocessor nti xa ib lub teeb liab mus rau lub valve. Thaum nws tau txais, cov roj kab qhib tshwm sim. Ib txhia immobilizers (uas yog - peb twb pom tau tias) yuav tsum txuas nrog rau ntau yam sensors, uas ua rau lawv ib tug analog teeb liab. Rau tej qauv nws yog ua tau los tswj los ntawm txoj kev lub paging system.

Siv ib tug standard chav tsev ntawm ib tug Immobiliser thiab ntau yam ntxiv li piav saum toj no, nws tseem tau mus ua ib lub tiv thaiv system rau lub tsheb.

hom ntawm pab kiag li lawm

Nyob rau hauv kev ua lag luam qauv, txawv tsim nta uas cuam tshuam tsis tsuas yog nyob rau functionality, tab sis kuj yuav txiav txim seb lub cia siab rau ntawm lub tag nrho qhov system.

Devices uas yuav tsum tau hu rau

Tiv tauj immobilizers xav tias tswj txhais tau tias qhov tseem ceeb tso rau hauv qhov dej los yog muab tso rau hauv qhov sib thooj rau lub mating xauv. Txawm li cas los, xws systems yuav luag tsis siv. Lawv tsiag ntawv los ntawm ib tug ncaj tseem ceeb drawback - lub attacker paub nyob rau hauv ua ntej qhov chaw uas lawv nyob.

Tiv tauj Immobiliser assumes tshwj xeeb code tswv yim los ntawm tus yuam sij mus. Cov nab npawb ntawm cov tseem ceeb ob peb ua ke yog zoo li no hais tias nws yog tsis yooj yim sua rau khaws cov code, tig tshaj ntau yam sequences. Cov nab npawb ntawm cov ob peb ua ke nyob rau hauv xws systems yog 10 degrees, sib nug xov mus rau lub xov tooj lag luam rau dialing ib tug code.

yuav tsum tsis txhob mus sib

Contactless immobilizers ua hauj lwm vim lub fact tias cov txais kav hlau txais xov system mounted rau sab hauv trim, thiab tus tswj cov txheej txheem yog nqa tawm los ntawm txoj kev ib daim ntawv los yog tseem ceeb FOB. Qhov no hom yog feem ntau. Qhov tseeb hais tias nws tsis yog tseeb qhov twg lub Immobiliser, kuas zoo dua tiv thaiv nyob rau hauv kev sib piv nrog rau lwm tus neeg. Txawm li cas los, muaj zoo kev daws teeb meem.

Contactless immobilizers me me voos kheej-kheej yus nyob rau hauv uas txais kav hlau txais xov hauj lwm ntawm ib tug deb ntawm tsis ntau tshaj 10 centimeters. Yuav tsaws nyob rau hauv lub tsheb nrog tam sim no daim ntawv lo rau ib tug thaum ntaus ntawv uas tso cai rau koj mus rau disarm cov system, account tag nrho cov saw. Yog hais tias ib tug criminal pom yuav ua li cas tus tsav tsheb puv lov tes taw Immobiliser, qhov uas nws coj cov tseem ceeb, nws tau ua tseeb tias lub tsheb siv ib co kev tiv thaiv. Nws yog ib qhov tsis muaj nruab nrog ib tug me me puag ncig ntawm kev txiav txim yog qhov tseem ceeb. Yog hais tias ib tug attacker pom qhov chaw uas koj xav kom coj daim ntawv lo, nws to taub qhov twg txais kav hlau txais xov nyob. Yog vim li cas lub tsheb yuav tsum disarm cov feem ntau hnov li cas.

Immobilizers, "tiv thaiv txoj kev khiav tawm" tso cai rau pib cov cav thiab rub deb, tab sis, ces thaiv tag nrho cov tshuab, thiab cov tsheb chaw. Tej systems yog heev tseem ceeb nyob rau hauv cov kev tshwm sim ntawm ib tug tub sab, thaum tus neeg tsav tsheb ces muab pov tseg los ntawm lub tsheb, coj cov yuam sij thiab cov ntaub ntawv. Txawm li cas los, qhov tseeb cia ntawm lub transponder tso cai rau nws mus nyob twj ywm rau tus tswv tsev. Thaum tus tswv tsev tsheb tub sab cais ib tug predetermined deb, lub cav chaw.

Yuav ua li cas kom tsis txhob raug nyiag lawm tsheb muaj?

Rau qhov no, ib yam nkaus thiab, yuav pab tau immobilizers. Ua li cas nws txhais li cas? Lub fact tias lawv tsim muaj ib qho kev hom xauv. Lockable saw tseem tsis tau tawg, yog hais tias lub cav tsis yog nyob rau hauv. Lawv yuav tsum qhib xwb thaum lub sij hawm nws tenure. Immobilisers nruab nrog ib tug nrog relay rau rhuav chains (feem ntau yog 3 daim).

Tsis ntev dhau los, nws yog siv raws li microdevices tshwj xeeb keyboards tswj los ntawm lub hauv paus unit los ntawm txoj kev high-zaus Pib ntsais koj teeb, thiab tsheb thaiv. Lawv yog cov yooj yim mus nrhiav tau thiab disarm, raws li lawv ua los ntawm lub hauv paus unit, tsis txhob mus. Tej relays mloog tsis txawv los ntawm ib tug pa tsheb. Tej zaum nws yog tso rau hauv ib tug tiv thaiv es tsis txhob ntawm tus txheej txheem, thiab kom paub qhov txawv lawv yog yuav luag tsis yooj yim sua. Ib txhia systems yuav txawm peem rau nrog ib tug kaum os cov ntawm no immobilizers, uas yog, nws yuav coj ib tug heev lub sij hawm ntev rau lawv tshawb.

Tej adaptation yog tseem tsim nyog los siv li pab mus rau lub tswb, es ib tug hloov. Lub ntsiab lus lawv ntsia encased nyob rau hauv secrecy thiab stealth rau lwm leej lwm tus, thiab qhov no yuav tsuas Immobiliser. "Kalina" thiab lwm yam qauv otchechestvennyh tsheb tau ntev tau tiv thaiv los ntawm allergic rau hauv lub hav zoov yog xws li pab kiag li lawm.

Yuav ua li cas mus tua?

Tej zaum nws tshwm sim hais tias tus tswv ntawm lub tshuab uas koj xav tau rau nws lov tes taw Immobiliser - nyob rau hauv cov kev tshwm sim ntawm ib tug malfunction los yog rhuav txhua ntawm cov ntsia tswb system, los yog rau lwm yam yog vim li cas. Nws ua li qhov zoo tshaj plaws nyob rau hauv ib tug tshwj xeeb Rhiav raws li ywj siab pab feem ntau ua ib tug qhov chaw ntawm ntxiv teeb meem - lub tsheb yuav nres los pib.

tswv yim pom zoo ntawm kev siv

- yuav tsum muaj tsawg kawg yog ntau tshaj ib tug Immobiliser tseem ceeb, thiab ob: ib tug yog mus yuav nrog koj, thiab lwm yam nyob rau lub tsev, nyob rau hauv cov kev tshwm sim ntawm ib tug thaum muaj xwm ceev;

- ib tug siv hluav taws xob yuav tsum tsis txhob dai nyob rau hauv lub zuag qhia tag nrho cov teeb ntawm lub lag luam;
