Nyiv tau tshaj tawm cov lus qhia rau cov cuab yeej ceeb toom no thaum Lub Ib Hlis 2010 thiab US tau pom zoo txoj cai nyob rau lub Kaum Ob Hlis 2010. US National Highway Traffic Safety Administration tau tshaj tawm nws cov lus txiav txim zaum kawg thaum Lub Ob Hlis 2018, thiab xav kom lub cuab yeej tawm suab ceeb toom thaum taug kev ntawm qhov ceev tsawg dua 18.6 mph. (30 km / h) nrog kev ua raws li lub Cuaj Hli 2020, tab sis 50% ntawm cov tsheb "tseem ceeb" yuav tsum muaj lub suab ceeb toom los ntawm lub Cuaj Hli 2019. Lub Plaub Hlis 2014, European Parliament tau pom zoo cov cai uas yuav tsum tau siv ntawm Acoustic Vehicle Alerting System ( AVAS).Cov neeg tsim khoom yuav tsum teeb tsa AVAS system nyob rau hauv plaub lub log hluav taws xob thiab cov tsheb sib txuas hluav taws xob uas tau pom zoo los ntawm Lub Xya Hli 1, 2019, thiab rau txhua lub tsheb uas ntsiag to thiab hybrid tshiab tau sau npe txij li Lub Xya Hli 2021. Lub tsheb yuav tsum ua kom lub suab nrov tsis tu ncua tsawg kawg yog 56. dBA (hauv 2 meters) yog tias lub tsheb mus 20 km / h (12 mph) lossis qeeb dua, thiab siab tshaj 75 dBA.
Ntau lub tuam txhab tsim hluav taws xob tau tsim hluav taws xob ceeb toom suab, thiab txij li lub Kaum Ob Hlis 2011 cov tsheb thev naus laus zis siab heev muaj nyob rau hauv kev ua lag luam nrog lub suab ceeb toom hluav taws xob suav nrog Nissan Leaf, Chevrolet Volt, Honda FCX Clarity, Nissan Fuga Hybrid / Infiniti M35, Hyundai Sonata Hybrid, thiab Toyota Prius (Nyiv nkaus xwb).Cov qauv nruab nrog cov tshuab ua haujlwm tau txais txiaj ntsig suav nrog 2014 BMW i3 (kev xaiv tsis muaj nyob hauv Asmeskas), 2012 qauv Toyota Camry Hybrid, 2012 Lexus CT200h, tag nrho EV versions ntawm Honda Fit, thiab tag nrho Prius tsev neeg lub tsheb nyuam qhuav qhia hauv Tebchaws Meskas. , suav nrog tus qauv 2012 qauv Prius, Toyota Prius v, Prius c thiab Toyota Prius Plug-in Hybrid.Lub 2013 Ntse hluav taws xob tsav, xaiv tau, tuaj nrog cov suab nrov nrov hauv Asmeskas thiab Nyij Pooj thiab ua haujlwm manually hauv Europe.
Enhanced Vehicle Acoustics (EVA), ib lub tuam txhab nyob hauv Silicon Valley, California thiab nrhiav tau los ntawm ob tug tub ntxhais kawm Stanford nrog kev pab los ntawm cov noob nyiaj los ntawm National Federation of the Blind, tsim ib qho kev lag luam tom qab hu ua "Vehicular Operations Sound Emitting Systems" (VOSES ).Cov cuab yeej ua rau hybrid hluav taws xob tsheb ua suab nrov zoo li cov pa hluav taws xob sab hauv lub cav tsheb thaum lub tsheb nkag mus rau hauv qhov ntsiag to hluav taws xob hom (EV hom), tab sis ntawm ib feem ntawm lub suab ntawm cov tsheb feem ntau.Thaum ceev tshaj li ntawm 20 mais ib teev (32 km / h) txog 25 mais toj ib teev (40 km / h) lub suab kaw.Lub kaw lus tseem kaw thaum lub cav hybrid combustion ua haujlwm.
VOSES siv cov lus me me, txhua lub caij huab cua uas tau muab tso rau ntawm lub hybrid lub log qhov dej thiab tso cov suab tshwj xeeb raws li cov kev taw qhia lub tsheb txav kom txo qis suab nrov thiab ua kom cov ntaub ntawv zoo tshaj plaws rau cov neeg taug kev.Yog hais tias lub tsheb mus rau pem hauv ntej, lub suab tsuas yog npaj rau pem hauv ntej;thiab yog lub tsheb tig sab laug lossis sab xis, lub suab hloov ntawm sab laug lossis sab xis kom tsim nyog.Lub tuam txhab sib cav hais tias "chirps, beeps thiab tswb yog qhov cuam tshuam ntau tshaj qhov muaj txiaj ntsig", thiab lub suab zoo tshaj plaws rau kev ceeb toom cov neeg taug kev yog lub tsheb zoo li, xws li "lub mos purr ntawm lub cav lossis lub log qeeb qeeb ntawm txoj kev taug kev."Ib qho ntawm EVA lub suab sab nraud tau tsim tshwj xeeb rau Toyota Prius.
