Chaw nres tsheb sensor
Feem ntau koj tsis pom qhov twg lub cev xaus thiab pib. Qee lub tsheb tau nruab nrog cov sensors nyob deb.
Niaj hnub nimno tsheb lub cev cov duab yog tsim nyob rau hauv xws li ib tug txoj kev uas tus neeg tsav tsheb qhov chaw saib thaum nres tsheb yog txwv.
Cov cuab yeej no ua kom yooj yim rau kev ua haujlwm hauv cov chaw nres tsheb nqaim thiab chaw nres tsheb uas muaj neeg coob. Xws li ib tug system ua hauj lwm zoo li ib tug echo sounder. Sensors nyob rau hauv lub bumpers, uas muaj ib tug piezoelectric caij nrog ib tug integrated circuit, emit ultrasounds ntawm ib tug zaus ntawm 25-30 kHz txhua 30-40 ms, uas rov qab raws li ib tug ncha tom qab xav txog los ntawm ib tug nyob ruaj ruaj khoom. Nyob rau hauv no stance, qhov kev ncua deb mus rau qhov teeb meem yog xam.
Qhov ntau ntawm cov cuab yeej yog los ntawm 20 mus rau 180 cm Nws yog qhib tau txais thaum lub iav rov qab koom nrog, thiab nyob rau hauv cov ntaub ntawv ntawm lub pem hauv ntej iav tau koom tom qab qhov ceev poob qis dua 15-20 km / h. Cov neeg siv feem ntau tuaj yeem tig lawv rau thiab tawm nrog lub pob.
Muaj ntau txoj hauv kev ntawm kev taw qhia qhov loj ntawm qhov kev nyab xeeb nyob deb: acoustic, lub teeb lossis ua ke. Lub ntim ntawm lub suab, xim lossis qhov siab ntawm cov xim muaj xim ntawm cov zaub nyob ntawm seb qhov chaw seem npaum li cas rau phab ntsa lossis lub bumper ntawm lwm lub tsheb. Feem ntau, thaum mus ze lawv ntawm qhov deb tsawg dua 35-20 cm, tus neeg tsav tsheb hnov cov teeb liab txuas ntxiv thiab pom cov cim flashing ntawm lub vijtsam.
Sensors nrog ib txoj kab uas hla ntawm 15 hli yuav muab tso rau hauv lub rear bumper, ces muaj 4-6 ntawm lawv, los yog tseem nyob rau hauv pem hauv ntej bumper - ces lawv tag nrho cov naj npawb yog 8-12. Qhov chaw nres tsheb sensor yog ib feem ntawm cov khoom qub ntawm lub tsheb lossis ib feem ntawm kev muab cov tuam txhab uas tsim cov khoom siv ntxiv.
