Lub VAZ-2114 yog nruab nrog lub tshuab niaj hnub injector sab hauv combustion engine. Kev ua haujlwm ntawm lub zog hluav taws xob yog tswj hwm los ntawm ECU (electronic engine control unit lossis "lub hlwb" ntawm lub tshuab). Nws yog nws leej twg yog lub luag hauj lwm rau lub sij hawm muab roj rau lub manifold, sparks rau ignite cov sib tov, nws yog lub luag hauj lwm rau kev ruaj ntseg ntawm lub engine nyob rau hauv tag nrho cov hom. Cia peb kawm seb yuav ua li cas cov "hlwb" ntawm VAZ-2114 ua haujlwm, hom dab tsi, lawv nyob qhov twg, lub computer nyob qhov twg, qhov ua haujlwm tsis zoo ntawm tus tswv yuav ntsib, yuav ua li cas kuaj cov cuab yeej no. Cov ntaub ntawv no yuav pab tau rau txhua tus tswv tsheb.

Kev piav qhia

Lub microprocessor yog siv los ua cov khoom tseem ceeb ntawm VAZ-2114 ECU. Nws lub luag haujlwm tseem ceeb yog tswj hwm tag nrho cov tshuab cav thaum nws pib thiab thaum lub sijhawm ua haujlwm hauv ntau hom thiab nyob rau hauv qhov sib txawv loads.

Lub tshuab hluav taws xob, raws li qee qhov kev ua haujlwm, sau tag nrho cov ntaub ntawv los ntawm cov sensors rau hauv ib qho tag nrho, thiab tom qab ntawdtxheej txheem lawv. "Lub hlwb" ntawm VAZ-2114 ua haujlwm nrog cov ntaub ntawv no txhawm rau muab cov lus teb txaus rau txhua qhov kev hloov pauv hauv lub tsheb, thiab tom qab ntawd kho cov haujlwm ntawm txhua lub tshuab rau cov qauv tsim los ntawm cov chaw tsim khoom.

Lub chaw tswj hluav taws xob kuj tseem tswj cov actuators hauv lub tsheb. Qhov no yog lub qhov cua, lub zog, hluav taws xob, kev kuaj mob, thiab kev tsis ua haujlwm.

ECU nco qauv

"Brains" VAZ-2114 yog tus cwj pwm los ntawm peb theem kev nco. Txhua qhov cascade yog qhov txawv los ntawm qhov muaj cov qauv ua haujlwm sib cais. Xav txog lawv kom meej:

RAM cascade yog lo lus paub rau cov neeg uas nkag siab txog lub cuab yeej thiab lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm PC. Lub zog ntawm RAM (random nkag tau lub cim xeeb) hauv qhov no kuj tsis muaj dab tsi tshiab. Cov cascade saum toj no yog ib qho thaiv ntawm RAM zoo tib yam, qhov chaw ua haujlwm tam sim no tau ua tiav

PROM thaiv (programmable nyeem nkaus xwb nco) yog lub cim xeeb ntev hauv VAZ-2114 ECU. Lub kaw lus muaj cov ntaub ntawv hais txog thaum tus neeg tsav tsheb xav tau kev saib xyuas. Daim ntawv qhia roj av, calibrations yav dhau los, tswj algorithms kuj muab khaws cia ntawm no. Tsis tas li ntawd nyob rau hauv lub block ntawm "lub hlwb" ntawm VAZ-2114, lub ntsiab firmware tau txais kev cawmdim. Cov ntaub ntawv nyob rau hauv lub cascade no yuav tsis raug tshem tawm. Yog tias peb kos ib qho piv txwv nrog lub khoos phis tawj, ces qhov no yog lub cuab yeej rau kev khaws cov ntaub ntawv mus tas li, lawv yuav tsis raug muab tshem tawm ntawm no. Thaum flashing lub "hlwb", kev hloov pauv tau ua ntawm no

theem tom ntej yog EEPROM (hluav taws xob reprogrammable nco). Nws yog caismodule. Nws lub luag haujlwm tseem ceeb yog tswj kev ua haujlwm ntawm kev tiv thaiv tub sab nyiag. Cov seem khaws cov encodings, passwords, txoj kev thiab cov yam ntxwv ntawm synchronizing cov ntaub ntawv ntawm EEPROM thiab cov immobilizer nyob rau hauv lub tsheb. Yog tias dheev, vim qee yam, cov ntaub ntawv pob ntawv tsis sib xws, lub cav tsheb yuav tsis pib

Txhua qhov module yog cais cais. Cov kev sib txuas ntawm lawv yog ua tib yam li hauv lub computer motherboard.

lub thawv tswj qhov twg

Raws li tus qauv tsim ntawm lub tsheb, "lub hlwb" ntawm VAZ-2114 yog nyob rau hauv lub torpedo.
