Uyu munsi, ndashaka gusobanura itandukaniro riri hagati ya sisitemu ya ECU ya SDLG na Volvo.
Abantu benshi bakundaga gutekereza ko sisitemu ya SDLG na Volvo ari imwe. Nukuri ko ibigo byombi byari bifite ubufatanye bwa hafi kandi bunoze mugihe cyambere mbere ya 2021, kandi ibicuruzwa byabo byatangiye kumurongo umwe. Ibi byatumye abantu benshi bumva nabi ko sisitemu zombi ari nyinshi cyangwa nkeya. Ariko, siko bimeze.
Ahagana mu 2021, SDLG yatangiye R&D yigenga itangira guteza imbere ibicuruzwa byayo bifasha. Ibi byari bikubiyemo ECU nyamukuru ya sisitemu yo kugenzura ibikoresho bya elegitoroniki, byakozwe mu bwigenge kandi byatejwe imbere na SDLG kandi bizwi mu nganda nka Sisitemu yo kugenzura ibikoresho bya elegitoroniki.
Reka turebe muri make ikibaho gikuru cya sisitemu ya Beigu. Igumana ibintu bimwe na bimwe bya sisitemu ya Volvo. Kurugero, isura yacyo isa na Volvo, ariko ibisobanuro bijyanye byahinduwe. Byongeye kandi, yakuyeho imikorere yumurongo umwe witumanaho 1587 uboneka muri sisitemu ya Volvo, igumana imikorere ya bisi ya CAN gusa.
Niyo mpamvu abakiriya benshi hamwe nabashinzwe gucukumbura bavuga ko badashobora kureba amakuru ya moteri ya moteri cyangwa amakuru yo gutabaza moteri kurubuga-ni ibisubizo bitaziguye bya SDLG ikuraho umurongo wo gutabaza 1587. Ibi kandi byasize abatekinisiye benshi basana urujijo no guharanira gukemura amakosa, akaba ari inenge yibi byahinduwe.
Kubwibyo, kwibutsa imirimo yo gusana: burigihe banza umenye moderi ya SDLG nubwoko bwa sisitemu ikoresha. Moderi yakozwe mbere ya 2021 birashoboka ko ifite sisitemu ya Volvo. Kuri moderi yakozwe nyuma ya 2021, cyangwa na bimwe byakozwe nyuma ya 2018 cyangwa 2019, igice gishobora gukoresha sisitemu ya Beigu. Urashobora kubatandukanya urebye hejuru yinyuma-hariho itandukaniro rikomeye hagati ya Volvo na Beigu ECUs. Sisitemu zitandukanye zisaba uburyo butandukanye bwo gukemura ibibazo.
Reka dufate urugero: tuvuge ko a 400 Wongeyeho icyitegererezo ifite ikibazo aho valve igereranya nta bisohoka. Uburyo bwo kwipimisha kuri ibi butandukanye nubwa Kawasaki ugereranije. Hamwe na sisitemu ya Beigu, urashobora guhagarika ibice bya valve ugereranije hanyuma ukabigerageza muburyo butaziguye. Mubihe bisanzwe kuriyi moderi, ugomba kuba ushobora gupima voltage ya 24V kuri interineti. Iyo valve igereranijwe imaze guhuzwa, voltage izamanuka muri 10V. Niba hari amakosa, voltage yapimwe kuri interineti ntabwo izaba 24V - irashobora kuba hafi ya volt icumi. Nibyo rwose wasanga mubizamini byafunguye.
Hariho andi makosa asanzwe. Kurugero, niba isaha ya metero yo gusoma a Icyitegererezo 600 mu buryo butunguranye asubira kuri 0, cyangwa agasimbuka kugeza ku bihumbi ijana cyangwa ibihumbi magana, amasaha arashoboka cyane murwego rwo kugenzura.
Ibindi bibazo nko kudashobora kuvugurura moteri cyangwa kunanirwa gutangira bisanzwe birashobora nanone guterwa nimikorere mibi ya ECU. Mu bihe nk'ibi, ECU igomba gukurwaho kugirango igerageze.
Aya ni amwe mumakosa asanzwe ajyanye na sisitemu ya Beigu. Nizere ko aya makuru afasha inshuti muruganda.
