Tsis ntev los no, lub tsheb tsav tus kheej yog lub ntsiab lus kub, thiab cov ntaub ntawv hais txog tsis yog qhov txawv.Qee lub tuam txhab xws li BMW, Benz txawm tau pib ua lawv cov qauv tsheb uas muaj kev ywj pheej.Rau ntau hom thiab siv tsheb, muaj cov sensors tshwj xeeb xws liKIA Auto SPEED Sensor, VW Oxygen Sensor thiab TOYOTA Air Flow Sensor.Kev tsav tsheb tus kheej tsis zoo li yog lub tswv yim tsis tseeb ntxiv rau peb.
Rau cov tsheb kom paub txog kev tsav tsheb tsis muaj zog, thawj qhov yuav tsum tau daws yog qhov teeb meem ntawm kev txhim kho kev nyab xeeb.Nws yog ib qho tseem ceeb uas yuav tsum tau nqis peev hauv lub sijhawm R & D.Lub tsheb yuav tsum tau nruab nrog "qhov muag" nrog lub zeem muag zoo thiab "lub hlwb" ci ntsa iab los lav kev nyab xeeb thiab automation.Thiab "qhov muag" yog txhua yam ntawm cov sensors thiab induction faucet ntsuas cov cuab yeej.
Hom sensors nyob rau hauv autonomous tsheb
Cov sensors yog lub koob yees duab, Lidar, Radar, IMU thiab Ultrasonic radar hauv autonomous sensors.Tom ntej no, cia peb qhia cov sensors feem.
Lub koob yees duab
Lub koob yees duab yog ib qho ntawmfeem ntau intuitive thiab nrov sensor hom, nws tsis yog tsuas yog siv nyob rau hauv autonomous tsheb.Lub koob npe nrov ntawm lub koob yees duab thiab lwm cov ntawv thov ua rau cov kws tshawb fawb los muab ntau yam kev pabcuam thev naus laus zis.Nyob rau hauv lem, muaj kev pab technologies tau ua tiav nyob rau hauv lwm yamthaj chaw thiab kev coj ua ntawm kev lag luam.Ob lub tsheb uas tsis muaj kev tswj hwm thiab tsis muaj kev tswj hwm siv ntau lub koob yees duab, nrog rau pem hauv ntej, nram qab, sab thiab dav.Yog li, lub koob yees duab tshuab tau siv zoo hauv kev lag luam tsheb.Lub zog ntawm lub koob yees duab uas yog khaws cia los ntawm lub koob yees duab tshwj xeeb lub xub pwg hnab are tus nqi qisthiab cov thev naus laus zis no yog qhov paub tab, vim muaj ntau tus neeg tsim cov algorithms nrog lub koob yees duab.Qhov tsis muaj zog yog tias lub koob yees duab raug txwv los ntawm lub teeb ci rau ib puag ncig zoo thiab nws nyuaj heev kom tau txais cov ntaub ntawv peb-dimensional meej (Lub koob yees duab Monocular yuav luag tsis tuaj yeem, thiab lub koob yees duab binocular lossis peb-ocular koob yees duab kuj tau thov).
Hais
Piv nrog rau lub koob yees duab, Lidar yog qhov tseem ceeb dua rau cov tsheb uas muaj kev ywj pheej.Laser radar tseem hu ua optical radar, luv luv hu ua Lidar.Lub laser radar yog kom ua tiav qhov kev tshawb pom ntawm lub hom phiaj los ntawm emitting laser beam, nws qhov kev kuaj pom tseeb yog siab dua, qhov kev tshawb pom ntau dua.Txawm li cas los xij, qhov tsis zoo ntawm lidar kuj pom tseeb.Lidar muaj kev cuam tshuam ntau dua rau kev cuam tshuam ntawm nag thiab daus huab cua hauv huab cua, thiab nws cov nqi siab kuj yog qhov laj thawj tseem ceeb txwv nws daim ntawv thov.
Tus kheej, qhov tseem ceeb tshaj plaws yog vim li cas lidar yog suav tias yog ib qho tseem ceeb tshaj plaws sensors rau autonomous tsheb yog nws qhov kom zoo dua hauv kev tsim peb-dimensional ib puag ncig qauv.Lub laser radar kis tau ntau txoj xov laser kab teeb los sau cov ntaub ntawv ib puag ncig ntawm qhov siab sib txawv, thiab los ntawm nws cov cuab yeej sib hloov sab hauv, cov ntaub ntawv tau sau nyob rau hauv thaj tsam ntawm 360 degrees hauv kab rov tav.Ib lub teeb liab txais cov cuab yeej ntawm lidar tuaj yeem khaws cov kab teeb ci laser uas tshwm sim los ntawm lub hom phiaj thiab tig mus rau hauv cov huab cua.Los ntawm kev ua cov ntsiab lus huab huab, nws tuaj yeem ua tiav cov kev faib tawm thiab kev txheeb xyuas cov ntaub ntawv ib puag ncig ib puag ncig.Txawm li cas los xij, txhua yam muaj nws qhov zoo thiab qhov tsis zoo.Qhov ntau cov xov xov lidar tuaj yeem kuaj pom qhov loj dua ntawm qhov chaw ib puag ncig, qhov loj dua ntawm cov ntaub ntawv huab cua nws tau txais, thiab ntau dua qhov yuav tsum tau ua rau kho vajtse haum cov ntaub ntawv muaj peev xwm ua tau.Tsis tas li ntawd, raws li cov khoom sib hloov hauv lub lidar yuav tsum tau hloov tas li thiab tawm cov kab teeb laser, cov khoom siv muaj cov khoom siv zoo salmosan azamethiphos cov kev cai rau kev hnav tsis kam thiab raug, uas tseem ua rau cov nqi siab ntawm lidar thiab yog li nce tus nqi ntawm cov tsheb autonomous. .Txawm li cas los xij, raws li thev naus laus zis txhim kho, nws ntseeg tau tias tus nqi thiab qhov loj ntawm lidar yuav raug txo kom tsawg, thaum qhov kev ua tau zoo yuav zoo dua.
Ultrasonic radar
Ultrasonic radar yog qhov ntsuas qis dua.Muaj ob hom ultrasonic radar.Thawj yog ntsia rau pem hauv ntej thiab rear bumper ntawm lub tsheb, uas yog siv los ntsuas lub rear thiab rear obstacles ntawm lub tsheb.Lub radar no hu ua UPA hauv kev lag luam.Hom thib ob, paub hauv kev lag luam li APA, yog ib qho ultrasonic radar uas tau nruab rau sab ntawm lub tsheb los ntsuas qhov kev ncua deb ntawm obstacles ntawm sab.Ob qhov kev kuaj pom thiab thaj tsam ntawm UPA thiab APA sib txawv.Kev kuaj pom qhov deb ntawm UPA feem ntau yog nyob nruab nrab ntawm 15-250cm, feem ntau yog siv rau cov teeb meem nyob rau hauv pem hauv ntej thiab nraub qaum ntawm lub tsheb, uas ntawm APA yog nyob ib ncig ntawm 30-500cm.Kev txheeb xyuas ntau yam ntawm APA yog dav dua, thiab tus nqi siab dua.
Qhov laj thawj vim li cas kuv tau hais tias ultrasonic radar yog qhov ntsuas qis qis yog tias nws tuaj yeem ua tau ntau lwm yam tshwj tsis yog kuaj pom cov teeb meem xws li chaw nres tsheb nrhiav pom thiab kev kub ceev sab nraud.
Qhov tseem ceeb ntawm sensors nyob rau hauv autonomous tsheb
Nrog rau acceleration ntawm txoj kev loj hlob ntawm cutting-edge technologies xws li autonomous tsav tsheb, qhov tseem ceeb thiab nkag mus rau tus sensors kuj tau txuas ntxiv txhim kho.Feem coob ntawm cov tsheb tsav tus kheej yuav tsum tau cia siab rau kev siv ntau hom sensors rau ntau yam duab pom, uas yog lub hauv paus tseem ceeb rau kev ua haujlwm thiab kev nyab xeeb ntawm lub tsheb.Yog li ntawd, nyob rau hauv tam sim no txoj kev loj hlob sai ntawm lub teb ntawm autonomous tsav tsheb, qhov tseem ceeb ntawm sensors tau ua qhov tseem ceeb.Tsis muaj qhov tsis ntseeg tias kev tsav tsheb tsis raug cai yuav yog ib qho ntawm cov kev lag luam tseem ceeb yav tom ntej, thiab nws qhov kev lag luam loj tuaj yeem xav txog.Los ntawm qhov kev pom no, yav tom ntej kev lag luam muaj peev xwm ntawm sensors kuj yuav loj heev.
Cov ntsiab lus
Peb tau paub txog kev siv thiab qhov tseem ceeb ntawm ntau yam sensors rau lub tsheb autonomous.YASEN yog ib lub chaw muag khoom zoo tshaj plaws los muab cov sensors.Nws muab txhua yam sensors rau ntau hom tsheb xws li KIA Auto SPEED sensor.Muaj kev txaus siab, koj tuaj yeem tiv tauj nws.
