Automotive microwave radar yog dab tsi
Automotive microwave radar yog lub tshuab radar uas siv microwaves rau kev kuaj pom, feem ntau yog siv hauv tsheb thiab lwm yam tsheb hauv av. Microwave radar ntes cov khoom hauv ib puag ncig ib puag ncig los ntawm kev xa thiab tau txais cov teeb liab microwave, kom ua tiav ntau yam haujlwm, xws li nrhiav pom kev cuam tshuam, ceeb toom kev sib tsoo, kev tswj xyuas kev caij nkoj, thiab lwm yam.
Txoj cai ua haujlwm
Automotive microwave radar ua haujlwm zoo ib yam li cov radar zoo tib yam, uas yog, nws xa cov yoj wireless (microwave) thiab tom qab ntawd tau txais cov ncha raws li lub sijhawm sib txawv ntawm kev txais thiab txais, thiaj li ntsuas cov ntaub ntawv ntawm lub hom phiaj. Tshwj xeeb, microwave radars emit microwave teeb liab uas thaws rov qab thaum lawv ntsib teeb meem, thiab lub radar xam qhov deb los ntawm kev ntsuas lub sij hawm mus ncig ntawm lub teeb liab. Tsis tas li ntawd, microwave radar tseem tuaj yeem kuaj xyuas qhov ceev thiab kev taw qhia ntawm ib qho khoom los ntawm kev txheeb xyuas cov yam ntxwv ntawm lub teeb pom kev zoo, xws li Doppler effect .
Daim ntawv thov scenario
Automotive microwave radar muaj ntau yam kev thov scenarios hauv tsheb:
Kev ceeb toom kev sib tsoo: los ntawm kev txheeb xyuas cov teeb meem ua ntej, ceeb toom ntxov, pab tus neeg tsav tsheb ntsuas kom tsis txhob muaj kev sib tsoo.
Adaptive cruise control : Nws tuaj yeem kho qhov ceev ntawm kev tsav nkoj raws li ib puag ncig ntawm lub tsheb, tswj kev nyab xeeb ntawm lub tsheb pem hauv ntej.
Kev tshawb nrhiav neeg taug kev : Hauv kev tsav tsheb tsis siv neeg, microwave radar tuaj yeem ntes cov neeg taug kev thiab lwm yam teeb meem kom muaj kev nyab xeeb ntawm kev tsav tsheb.
Tsis siv neeg nres tsheb: Pab lub tsheb tuaj yeem nrhiav qhov chaw nres tsheb zoo hauv qhov chaw nres tsheb thiab ua kom tiav qhov chaw nres tsheb.
Technical parameters thiab kev ua haujlwm zoo
Automotive microwave radars feem ntau ua haujlwm hauv millimeter yoj bands, xws li 24GHz, nrog ntau zaus thiab luv wavelengths. Qhov no ua rau microwave radar muaj kev ncaj ncees thiab kev daws teeb meem, thiab tuaj yeem txheeb xyuas cov hom phiaj ze ze. Tsis tas li ntawd, lub microwave radar tsis cuam tshuam los ntawm kev pom thiab tuaj yeem ua haujlwm ib txwm nyob rau hauv huab cua phem. Txawm li cas los xij, tus nqi ntawm microwave radar yog qhov siab, thiab lub peev xwm los ntes cov khoom me me tsis zoo li lidar .
Lub luag haujlwm tseem ceeb ntawm automotive microwave radar suav nrog cov hauv qab no:
Kev ceeb toom kev sib tsoo thiab tsis siv neeg ceev ceev nres (AEB) : Microwave radars ntes cov teeb meem ua ntej thiab yog tias tsim nyog ua rau muaj qhov tsis siv neeg nres thaum muaj xwm ceev los tiv thaiv kev sib tsoo.
Kev tshawb nrhiav neeg taug kev: Los ntawm microwave radar, lub tsheb tuaj yeem paub thiab pom cov neeg taug kev, yog li txhim kho kev nyab xeeb ntawm kev tsav tsheb.
Kev saib xyuas qhov muag tsis pom kev thiab txoj kab lus ceeb toom tawm mus: microwave radar tuaj yeem saib xyuas thaj chaw qhov muag tsis pom ntawm lub tsheb kom tiv thaiv kev sib tsoo nrog lwm lub tsheb thaum hloov txoj kab, thiab tuaj yeem saib xyuas txoj kev tawm mus thiab ceeb toom cov neeg tsav tsheb.
Adaptive cruise control (ACC) : Microwave radar tuaj yeem pab cov tsheb tswj kom muaj kev nyab xeeb ntawm lub tsheb nyob rau pem hauv ntej ntawm kev tswj kev caij nkoj.
Kev Ceeb Toom Tsheb Hauv Tsheb (RCTA): microwave radar tuaj yeem saib xyuas cov tsheb khiav hauv qab lub tsheb, ceeb toom tus neeg tsav tsheb kom xyuam xim rau lub tsheb yuav los, kom tsis txhob rov qab sib tsoo.
Lub hauv paus ntsiab lus ua haujlwm ntawm microwave radar yog ntsuas qhov chaw ntawm lub hom phiaj los ntawm kev xa cov nthwv dej tsis muaj zog (radar nthwv dej) thiab tau txais cov ncha raws li lub sijhawm sib txawv ntawm kev xa thiab txais. Qhov zaus ntawm millimeter yoj radar yog nyob rau hauv millimeter yoj band, yog li nws hu ua millimeter wave radar .
Daim ntawv thov sib txawv zaus ntawm microwave radar hauv tsheb muaj xws li ob pawg ntawm 24GHz thiab 77GHz. 24GHz radars feem ntau yog siv rau kev tshawb pom luv luv, thaum 77GHz radars muaj kev daws teeb meem siab dua thiab me me, haum rau kev tshawb pom ntev dua.
