Q1: Umutekano ukora utangirana nigishushanyo?
A1: Kugira ngo bisobanuke neza, niba ari ngombwa kubahiriza ibicuruzwa ISO 26262, ibikorwa byumutekano bigomba gutegurwa mugitangira umushinga, hagomba gutegurwa gahunda yumutekano, kandi gushyira mubikorwa ibikorwa byumutekano muri gahunda bigomba gukomeza gutezwa imbere. hashingiwe ku micungire yubuziranenge kugeza ibikorwa byose byo gushushanya, iterambere no kugenzura birangiye kandi hashyizweho dosiye yumutekano.Mugihe cyo gusuzuma ibyemezo, ubugenzuzi bwumutekano bukora kugirango hamenyekane neza ibicuruzwa byingenzi byakazi kandi byubahirizwe, kandi amaherezo bigomba kwerekana urugero rwibicuruzwa byubahirizwa na ISO 26262 binyuze mugusuzuma umutekano.Kubwibyo, ISO 26262 ikubiyemo ibikorwa byuzuye byubuzima bwumutekano wibicuruzwa bijyanye na elegitoroniki / amashanyarazi.
Q2: Nubuhe buryo bwo kwemeza umutekano bukora kuri chip?
A2: Dukurikije ISO 26262-10 9.2.3, dushobora kumenya ko chip ikora nkibintu byumutekano bitavuzwe (SEooC), kandi inzira yiterambere ryayo mubisanzwe irimo ibice 2,4 (ibice) 5,8,9, niba guteza imbere software no gukora ntibisuzumwa.
Ku bijyanye no gutanga ibyemezo, bigomba kugenwa hakurikijwe amategeko yo gushyira mu bikorwa ibyemezo bya buri rwego.Mubisanzwe, mubikorwa byose byiterambere rya chip, hazabaho ibice 2 kugeza kuri 3 byubugenzuzi, nkubugenzuzi bwicyiciro cyateguwe, ubugenzuzi bwibishushanyo mbonera niterambere, hamwe nubugenzuzi bwikizamini no kugenzura.
Q3: Akazu kabanyabwenge karimo ki?
A3: Mubisanzwe, sisitemu ijyanye numutekano ya elegitoroniki / amashanyarazi ikikije kabine yubwenge ni ASIL B cyangwa munsi yayo, igomba gusesengurwa ukurikije imikoreshereze nyayo yibicuruzwa nyirizina, kandi urwego rwa ASIL rushobora kuboneka binyuze muri HARA, cyangwa Urwego rwa ASIL rwibicuruzwa rushobora kugenwa binyuze mugusabwa kwa FSR.
Q4: Kuri ISO 26262, nikihe gice gito kigomba kugeragezwa?Kurugero, niba turi igikoresho cyingufu, dukeneye kandi gukora ISO 26262 kwipimisha no kugenzura mugihe dukora urwego rwa gage?
A4: ISO 26262-8: 2018 13.4.1.1. , gusa dukeneye kubahiriza amabwiriza yimodoka (nka AEC-Q).Kubireba ubwoko bwa kabiri bwibintu (ibyuma byubushyuhe, ADC yoroshye, nibindi), birakenewe ko harebwa uburyo hariho uburyo bwumutekano wimbere bujyanye nigitekerezo cyumutekano kugirango hamenyekane niba bigomba kwitabwaho kugirango hubahirizwe ISO 26262 ;Niba ari icyiciro cya 3 (MCU, SOC, ASIC, nibindi), birasabwa kubahiriza ISO 26262.
GRGTEST imikorere yumutekano wa serivisi
Hamwe n'uburambe bukomeye bwa tekiniki hamwe nibibazo byatsinzwe mugupima ibicuruzwa bya sisitemu ya gari ya moshi na gari ya moshi, turashobora gutanga serivisi zipimishije no gutanga ibyemezo byimashini zose, ibice, semiconductor nibikoresho fatizo bya Oems, abatanga ibice hamwe ninganda zishushanya chip kugirango tumenye neza, kuboneka , kubungabunga no kubungabunga ibicuruzwa.
dufite tekinoroji yumutekano ikora neza, yibanda kumutekano wibikorwa (harimo inganda, gari ya moshi, amamodoka, umuzunguruko uhuriweho nizindi nzego), umutekano wamakuru hamwe ninzobere zumutekano ziteganijwe, hamwe nuburambe bukomeye mugushyira mubikorwa umuzunguruko, ibice hamwe nibikorwa rusange umutekano.Turashobora gutanga serivisi imwe yo guhugura, kugerageza, kugenzura no gutanga ibyemezo kubakiriya mu nganda zitandukanye dukurikije ibipimo byumutekano byinganda.
