Nyob rau hauv tus txheej txheem ntawm kev siv cov cuab yeej tsav tsheb ntse, daim ntawv thov scenarios ntawm onboard LiDAR FPC yog tas li nthuav nrog tsheb qauv hloov khoom dua tshiab thiab ua hauj lwm iterations.
1, Adaptation daim ntaub ntawv nyob rau hauv ntau theem ntawm lub ntse tsheb qauv
(1) Cov kev nkag siab yooj yim rau kev nkag - qib cov qauv tsheb ntse
Rau kev nkag - theem ntse tsheb nruab nrog L2 qib kev pab tsav tsheb ua haujlwm, lawv LiDAR feem ntau siv ib txoj kab qis qis (xws li 16 kab lossis 32 kab), feem ntau yog lub luag haujlwm rau kev tshawb nrhiav qhov teeb meem. Lub sijhawm no, lub luag haujlwm tseem ceeb ntawm FPC yog los txuas lub laser emitting module nrog lub ntsiab tswj nti, ua kom tiav cov ntaub ntawv yooj yim kis tau tus mob nyob rau hauv ib qho kev txwv qhov chaw. Piv txwv li, nyob rau hauv pem hauv ntej bumper ntawm ib tug compact SUV nrog ib tug ua tau - nyob rau hauv radar, FPC khoov 90 degrees nyob ib ncig ntawm lub tshav kub dissipation tivthaiv kom stably xa mus rau ntau pua txhiab tus laser reflection signals ib ob mus rau lub ua chav tsev, xyuas kom meej cov lus teb raug ntawm AEB (Automatic Emergency Braking) muaj nuj nqi.
(2) Ntau lub radar sib koom ua ke rau nruab nrab mus rau siab kawg tsheb qauv
L3 qib thiab siab dua cov qauv tsheb txawj ntse feem ntau tau nruab nrog ntau lub laser radars (xws li lub ru tsev + sab saib ua ke), tsim 360℃qhov muag tsis pom kev network. FPC xav tau kev daws teeb meem ntau qhov teeb liab synchronization teeb meem hauv cov xwm txheej zoo li no: FPC ntawm lub ru tsev lub ntsiab radar yuav tsum tau txuas nrog ob lub tshuab hluav taws xob encoder thiab lub laser txais array, thaum FPC ntawm sab saib radar yuav tsum tau tiv thaiv qhov kev ntxhov siab khoov los ntawm lub qhov rooj qhib thiab kaw. Nyob rau hauv lub ru tsev radar module ntawm ib tug khoom kim heev hom lub ntshiab hluav taws xob lub tsheb qauv, lub customized FPC yog tsim los nrog nab zoo li thaiv, uas tsis tsuas yog ua tau raws li qhov yuav tsum tau ntawm dynamic kev twb kev txuas ntawm rotating Cheebtsam, tab sis kuj tswj lub ncua ntawm ntau radar cov ntaub ntawv kis tau tus mob nyob rau hauv microseconds.
2, Customized daim ntaub ntawv nyob rau hauv tshwj xeeb tsheb qauv thiab scenarios
(1) Durability Application of Commercial Vehicles and Special Vehicles
Lub LiDAR ntawm cov tsheb lag luam xws li cov tsheb thauj khoom thiab tsheb engineering feem ntau raug cuam tshuam rau kev ua haujlwm nyuaj, thiab lawv FPC yuav tsum muaj cov yam ntxwv ntawm kev tiv thaiv roj av thiab kub thiab kub tsis kam. Nyob rau hauv lub radar system ntawm chaw nres nkoj autonomous tsav tsheb thawv tsheb, FPC siv polyimide substrate thiab kub-plated hu, uas yuav ua hauj lwm ruaj khov nyob rau hauv ib puag ncig ntawm -40℃mus rau 85 degree, thaum tiv thaiv yaig ntawm seawater ntsev tsuag. Lub neej khoov ntawm hom FPC no tuaj yeem ncav cuag ntau dua 100000 zaug, uas txaus los txhawb kev ua haujlwm ntev ntawm cov tsheb lag luam.
(2) High ceev daim ntawv thov ntawm autonomous tsav tsheb xeem
Cov tsheb tsav tsheb uas siv hluav taws xob siv hluav taws xob siv rau kev tshawb fawb thiab kev tsim kho technology feem ntau yog nruab nrog ntau hom thiab hom LiDAR rau kev sib piv cov ntaub ntawv. FPC ua lub luag haujlwm ntawm "universal interface" hauv cov xwm txheej zoo li no: los ntawm kev tsim qauv, tib FPC tuaj yeem hloov kho rau radar modules los ntawm cov tuam txhab sib txawv, ua tiav cov qauv kev sib kis ntawm lub zog thiab cov ntaub ntawv teeb liab. Hauv kev sim nkoj ntawm qee lub tuam txhab tsav tsheb, lub radar adapter board nrog pluggable FPC tau siv, uas ua rau lub sijhawm hloov radar luv los ntawm 2 teev mus rau 15 feeb, txhim kho kev sim ua tau zoo.
3, Kev sib txuas daim ntawv thov nrog lwm yam hauv lub tshuab tsheb
(1) Fusion kev nkag siab nrog millimeter yoj radar thiab lub koob yees duab
Nyob rau hauv ntau-sensor fusion tswv yim ntawm kev tsav tsheb ntse, lub laser radar FPC yuav tsum tau ua haujlwm nrog rau cov kab hluav taws xob ntawm lwm cov sensors. Nyob rau hauv pem hauv ntej sensing sib dhos ntawm ib tug tej yam tsheb qauv, lub laser radar FPC yog cais los ntawm lub millimeter yoj radar RF Circuit Court los ntawm ib tug shielding txheej kom tsis txhob teeb liab cuam tshuam; Tib lub sijhawm txuas mus rau tus tswj hwm tus tswj hwm los ntawm tib pawg ntawm kev sib cuam tshuam kom ua tiav synchronous kis ntawm cov ntaub ntawv huab cua thiab cov ntaub ntawv duab, muab cov tswv yim sib txuas rau ib puag ncig kev nkag siab algorithms.
(2) Adaptation daim ntawv thov nrog automotive qib cua txias system
Lidar ua kom muaj cua sov ntau thaum lub sijhawm ua haujlwm siab - zaus, thiab nws FPC yuav tsum tau ua tib zoo koom tes nrog cov qauv cua sov. Nyob rau hauv ib qho khoom siv - xeev laser radar module, tooj liab ntawv ci Circuit Court ntawm FPC ib txhij lees txais cov teeb liab kis tau tus mob thiab kub conduction zog. Los ntawm kev taw qhia cov cua sov ua haujlwm ntawm cov nti mus rau txhuas lub dab dej kub, qhov ua haujlwm kub ntawm lub radar yog txo los ntawm 15 degree, kom tsis txhob muaj kev puas tsuaj los ntawm kev kub siab. Qhov no 'kev siv dual' tsim tsis tsuas yog txuag chaw xwb tab sis kuj txhim kho kev ntseeg tau.
