Q&A ye-ISO 26262 (InxalenyeⅠ)

I-Q1: Ngaba ukhuseleko olusebenzayo luqala ngokuyila?
A1: Ukuchaneka, ukuba kuyimfuneko ukuthobela iimveliso ze-ISO 26262, imisebenzi efanelekileyo yokhuseleko kufuneka icwangciswe ekuqaleni kweprojekthi, isicwangciso sokhuseleko kufuneka siqulunqwe, kwaye ukuphunyezwa kwemisebenzi yokhuseleko kwisicwangciso kufuneka kukhuthazwe ngokuqhubekayo. ngokusekelwe kulawulo lomgangatho kude kube yonke imisebenzi yoyilo, uphuhliso kunye nokuqinisekiswa igqityiwe kwaye ifayile yokhuseleko yenziwe.Ngexesha lokuphononongwa kokuvunywa, uphicotho olusebenzayo lokhuseleko lokuqinisekisa ukuchaneka kweemveliso eziphambili zomsebenzi kunye nokuthotyelwa kwenkqubo, kwaye ekugqibeleni kufuneka kuqinisekiswe inqanaba lokuthotyelwa kwemveliso kunye ne-ISO 26262 ngovavanyo lokhuseleko olusebenzayo.Ke ngoko, i-ISO 26262 igubungela umjikelo wobomi opheleleyo wemisebenzi yokhuseleko enxulumene nokhuseleko lweemveliso zombane/zombane.

I-Q2: Yintoni inkqubo yokuqinisekisa ukhuseleko olusebenzayo lweechips?
A2: Ngokutsho kwe-ISO 26262-10 9.2.3, siyakwazi ukuba i-chip isebenza njengento yokhuseleko ngaphandle komxholo (SEooC), kunye nenkqubo yophuhliso ngokuqhelekileyo ibandakanya iinxalenye 2,4 (amacandelo) 5,8,9, ukuba uphuhliso lwesoftware kunye nokuveliswa akuqwalaselwa.
Xa kuziwa kwinkqubo yokuqinisekiswa, kufuneka kugqitywe ngokwemigaqo yokuphunyezwa kwesatifikethi yequmrhu ngalinye lesatifikethi.Ngokuqhelekileyo, kuyo yonke inkqubo yokuphuhliswa kwe-chip, kuya kuba ne-2 ukuya kwi-3 iindawo zophicotho, ezifana nokuphicothwa kwenqanaba lokucwangcisa, uphicotho loyilo kunye nenqanaba lophuhliso, kunye nophicotho lovavanyo kunye nenqanaba lokuqinisekisa.

I-Q3: Yeyiphi iklasi ye-smart cabin?
I-A3: Ngokuqhelekileyo, inkqubo enxulumene nokhuseleko lwe-elektroniki / yombane ejikeleze i-cabin ehlakaniphile yi-ASIL B okanye ngaphantsi, ekufuneka ihlalutywe ngokubhekiselele kusetyenziso lwangempela lwemveliso, kunye nenqanaba elichanekileyo le-ASIL linokufumaneka nge-HARA, okanye Umgangatho we-ASIL wemveliso unokumiselwa ngokwemfuno yolwabiwo lweFSR.

Q4: Kwi-ISO 26262, yeyiphi eyona yunithi incinci ekufuneka ivavanywe?Umzekelo, ukuba sisixhobo samandla, ngaba sikwafuna ukwenza uvavanyo lwe-ISO 26262 kunye nokuqinisekisa xa sisenza amanqanaba egaraji yesithuthi?
I-A4: ISO 26262-8: 2018 13.4.1.1 (isahluko sovavanyo lwezixhobo ze-Hardware) iya kwahlula i-hardware kwiintlobo ezintathu zezinto, uhlobo lokuqala lwezixhobo ze-hardware ubukhulu becala luyi-discrete components, i-passive components, njl. Akukho mfuneko yokuqwalasela i-ISO 26262 , kufuneka kuphela ukuthobela imigaqo yesithuthi (efana ne-AEC-Q).Kwimeko yohlobo lwesibini lwezinto (izinzwa zobushushu, ii-ADCs ezilula, njl. njl.), kuyimfuneko ukujonga ubukho beendlela zokhuseleko lwangaphakathi ezinxulumene nombono wokhuseleko ukujonga ukuba ngaba kufuneka kuthathelwe ingqalelo ukuthotyelwa kwe-ISO 26262 ;Ukuba yinxalenye yoDidi 3 (MCU, SOC, ASIC, njl.), kufuneka ihambelane ne-ISO 26262.

GRGTEST umsebenzi wenkonzo yokhuseleko isakhono

Ngamava obugcisa atyebileyo kunye namatyala aphumeleleyo kuvavanyo lweemoto kunye nemveliso yenkqubo kaloliwe, sinokubonelela ngovavanyo olubanzi kunye neenkonzo zesiqinisekiso soomatshini bonke, iinxalenye, i-semiconductor kunye nezinto ezikrwada ze-Oems, ababoneleli beenxalenye kunye namashishini oyilo lwetshiphu ukuqinisekisa ukuthembeka, ukufumaneka. , ukugcinwa kunye nokhuseleko lweemveliso.
sineqela lokhuseleko elisebenzayo kubuchwepheshe obuphezulu, lijolise kukhuseleko olusebenzayo (kubandakanya umzi-mveliso, uloliwe, iimoto, isekethe edibeneyo kunye nezinye iinkalo), ukhuseleko lolwazi kunye neengcali ezilindelekileyo zokhuseleko olusebenzayo, kunye namava atyebileyo ekuphunyezweni kwesekethe edibeneyo, icandelo kunye nokusebenza ngokubanzi. ukhuseleko.Sinokubonelela ngeenkonzo zokumisa enye yoqeqesho, uvavanyo, uphicotho kunye nesatifikethi kubathengi kumashishini ahlukeneyo ngokwemigangatho yokhuseleko yoshishino oluhambelanayo.
