CAN lub rooj vag lossis lub rooj vag tsheb vim lub rooj vag tswj tsis tau tsuas yog CAN network tab sis kuj yog LIN network.
Cov qauv qauv ntawm CAN gateway:
Qhov tseeb qhov rooj muaj peev xwm muaj txog 60 lossis 70 tus pin txuas, thiab txhua tus pin txuas muaj lub ntsiab lus nruj. Nws yuav tsum ua raws li qhov teev tseg tuaj yeem tsheb npav lossis hloov khoom siv, tshwj tsis yog rau 10 tuaj yeem kab thaiv cov chaw nres nkoj (5 twisted khub) tsuas yog koom nrog. cable), 2 lub hwj chim cable terminals, thiab yuav tsum muaj xws li: 8 terminals rau cruise control khoom, 3 terminals rau kev tswj fais fab, 5 terminals rau qhov tseem ceeb hloov (los yog keyless start system), ko taw pedal 3 thaiv chaw nres nkoj, 5 LIN thaiv pins, 4 txuas pins ntawm lub iav hloov, thiab lwm yam.
Qee lub tuam txhab tsheb yuav muaj cov cuab yeej hloov kho tshiab ntau dua, cov khoom siv hluav taws xob hloov hluav taws xob, thiab lwm yam kuj tseem muaj cov hlua txuas sib txuas, thiab tuaj yeem khaws qee tus pins rau thaub qab.
Lub rooj vag CAN yog lub hauv paus tseem ceeb ntawm tag nrho CAN network thiab tswj kev xa mus thiab ua tiav ntawm ntau lub cim ntawm tsib lub tsheb npav CAN hauv lub tsheb. Cov haujlwm tseem ceeb suav nrog:
1. Txuas CAN tsheb npav / LIN tsheb npav nrog sib txawv baud tus nqi (kev sib kis ceev) kom paub txog lub rooj vag relay muaj nuj nqi ntawm CAN network.
2. Kev xa cov pob ntawv kuaj mob / cov pob ntawv tsis kuaj mob.
3. Ntsuam xyuas kev tswj firewall.
4. Node saib xyuas online.
5. Cruise controller hloov nrhiav kom tau.
6. Ko taw pedal txoj hauj lwm nrhiav kom tau.
7. Rooj vag pw tsaug zog thiab tswj kev sawv.
8. ECU upgrade/gateway upgrade.
9. Kev tswj hluav taws xob.
Lub rooj vag CAN tuaj yeem tau txais cov xov tooj sib txawv ntawm cov kab sib txawv ntawm cov tsheb npav CAN (thiab LIN tsheb npav), ua cov cim no raws li qee cov qauv, thiab tshaj tawm rau hauv lub tsheb network. Yog tias ECU sau npe (tau txais) cov teeb liab no, Tom qab ntawd ECU yuav txheeb xyuas cov teeb liab thiab ua cov txheej txheem sib xws.
Txhua ECUs nyob rau hauv tag nrho lub tsheb pib xa thiab txais cov teeb liab tsis tu ncua ntawm qhov ceev ntawm milliseconds lossis microseconds, yog li lub rooj vag yuav tsum tau ua thiab xa cov xov tooj cua tshaj tawm ntau heev thiab yuav tsum tau ua tiav sai.
