Izandi zokulumkisa isithuthi sombane

I-Japan ikhuphe izikhokelo zezixhobo ezilumkiso ezinjalo ngoJanuwari 2010 kunye nomthetho wase-US ovunyiweyo ngoDisemba 2010. ULawulo lweSizwe loKhuseleko lweNdlela ePhakamileyo lwase-US lukhuphe isigqibo salo sokugqibela ngoFebruwari 2018, kwaye lufuna isixhobo sikhuphe izandi zesilumkiso xa sihamba ngesantya esingaphantsi kwe-18.6 mph. (i-30 km / h) ngokuthotyelwa ngoSeptemba 2020, kodwa i-50% yezithuthi "ezizolileyo" kufuneka zibe nezandi zokulumkisa ngoSeptemba 2019. Ngo-Ephreli 2014, iPalamente yaseYurophu ivume umthetho ofuna ukusetyenziswa okunyanzelekileyo kwe-Acoustic Vehicle Alerting System ( AVAS).Abavelisi kufuneka bafake inkqubo ye-AVAS kwiimoto ezine zombane kunye ne-hybrid zombane ezivunyiweyo ukusuka ngoJulayi 1, 2019, kunye nazo zonke iimoto ezintsha zombane ezithe cwaka kunye ne-hybrid ezibhaliswe ukususela ngoJulayi 2021. Isithuthi kufuneka senze umgangatho wengxolo oqhubekayo ubuncinane we-56 dBA (ngaphakathi kweemitha ezi-2) ukuba imoto ihamba nge-20 km/h (12 mph) okanye icotha, kunye nobuninzi be-75 dBA.

automakers abaliqela baye baphuhlisa izixhobo isilumkiso sombane isilumkiso, kwaye ukususela ngoDisemba 2011 iimoto zobuchwepheshe obuphambili ekhoyo kwimarike kunye nezandi isilumkiso zombane ngesandla isebenze ziquka i Nissan Leaf, Chevrolet Volt, Honda FCX Clarity, Nissan Fuga Hybrid / Infiniti M35, Hyundai Sonata Hybrid, kunye iToyota Prius (eJapan kuphela).Iimodeli ezixhotyiswe ngeenkqubo ezisebenza ngokuzenzekelayo ziquka i-BMW i3 ka-2014 (ukhetho alufumaneki e-US), imodeli yonyaka ka-2012 iToyota Camry Hybrid, i-2012 Lexus CT200h, zonke iinguqulelo ze-EV zeHonda Fit, kunye nazo zonke iimoto zentsapho yakwaPrius ezisanda kuqaliswa eUnited States. , kubandakanywa umgangatho we-2012 wemodeli yePrius, iToyota Prius v, iPrius c kunye neToyota Prius Plug-in Hybrid.I-2013 Smart electric drive, ngokuzikhethela, iza nezandi ezisebenza ngokuzenzekelayo e-US nase-Japan kwaye yenziwe ngesandla eYurophu.

I-Enhancence Vehicle Acoustics (EVA), inkampani esekwe eSilicon Valley, eCalifornia kwaye yasekwa ngabafundi ababini baseStanford ngoncedo lwemali yembewu evela kwiNational Federation of the Blind, yavelisa iteknoloji emva kweemarike ebizwa ngokuba yi "Vehicular Operations Sound Emitting Systems" (VOSES). ).Isixhobo senza ukuba izithuthi zombane ezixutyiweyo zivakala ngakumbi njengeenjini zenjini eziqhelekileyo zokutsha zangaphakathi xa isithuthi singena kwimowudi yombane ethuleyo (imowudi ye-EV), kodwa kwiqhezu lenqanaba lesandi sezithuthi ezininzi.Ngesantya esingaphezu kweekhilomitha ezingama-32 ngeyure ukuya kwezingama-40 ngeyure, isandisi-lizwi siyacima.Inkqubo iphinda ivale xa injini yokutshisa i-hybrid iyasebenza.

I-VOSES isebenzisa ii-miniature, izithethi zeaudio zemozulu yonke ezibekwe kumaqula amavili e-hybrid kwaye zikhupha izandi ezithile ezisekelwe kwicala lemoto ehamba kuyo ukuze kuncitshiswe ungcoliseko lwengxolo kunye nokwandisa ulwazi lwe-acoustic kubahambi ngeenyawo.Ukuba imoto ihamba phambili, izandi ziboniswa kuphela kwicala eliya phambili;yaye ukuba inqwelo-mafutha ijikela ngasekhohlo okanye ngasekunene, isandi siyatshintsha ngasekhohlo okanye ngasekunene ngokufanelekileyo.Inkampani ixoxa ngelithi "iitshiphu, ii-beep kunye nee-alam ziphazamisa ngakumbi kunokuba ziluncedo", kwaye ezona zandi zibalaseleyo zokulumkisa abahambi ngeenyawo zifana nemoto, "njenge-purr ethambileyo ye-injini okanye ukucotha kwamatayara kwipavumente."Enye yeenkqubo zesandi zangaphandle ze-EVA zenzelwe ngokukodwa iToyota Prius.
