Kev nce ntawm kev tsav tsheb tsis siv neeg kuj xav tau sensors los txhawb nws
Tam sim no, muaj txog 100 sensors ntsia rau hauv tsev neeg lub tsheb, thiab tus naj npawb ntawm cov sensors ntawm lub tsheb khoom kim heev yog txog 200. Yog li muaj pes tsawg lub sensors tsis siv neeg tsav tsheb yuav tsum tau txhawb nqa raws li lub tsheb tseem ceeb hauv lub neej yav tom ntej?
In the past two years, China's automatic driving technology has continued to iterate and make breakthroughs. Automatic driving trucks, mining cars, logistics park cars, patrol cars and taxis have appeared in daily production and life. In the process of being recognized by people, new technologies are also being commercialized and tested to explore the future commercialization operation mode.
Cov kws tshaj lij tau taw qhia tias kev siv dav dav ntawm kev tsav tsheb tsis siv neeg yog qhov zoo rau kev txuag qee lub zog ua haujlwm thiab ua kom yooj yim rau cov neeg tsav tsheb tsis yooj yim. Tsis tas li ntawd, txoj kev tsav tsheb ntawm lub tsheb autopilot yog lub zog ntau dua thiab tuaj yeem txo cov tsheb thauj mus los thiab cov pa phem.
Tam sim no, muaj txog 100 sensors ntsia rau hauv tsev neeg lub tsheb, thiab tus naj npawb ntawm cov sensors ntawm lub tsheb khoom kim heev yog txog 200. Yog li muaj pes tsawg lub sensors tsis siv neeg tsav tsheb yuav tsum tau txhawb nqa raws li lub tsheb tseem ceeb hauv lub neej yav tom ntej?
Cov yam ntxwv ntawm lub sensor muaj xws li miniaturization, digitization, intellectualization, multifunction, systematization thiab networking. Nws yog qhov txuas tseem ceeb kom paub txog kev tshawb nrhiav tsis siv neeg thiab tswj tsis siv neeg. Lub hav zoov thiab kev loj hlob ntawm cov sensors ua rau cov khoom muaj kev xav xws li kov, saj thiab tsw, thiab ua kom cov khoom maj mam ua ciaj sia.
Tam sim no, qhov teeb meem loj tshaj plaws hauv kev nkag siab yog kev ntsuas qhov tseeb thiab ntau -sensor fusion. Lub ntsiab sensor yog ultrasonic radar. Ob peb qauv txais kev teeb tsa ntawm ultrasonic radar ntxiv rau lub koob yees duab. Vim hais tias tus nqi ntawm lidar yog siab dhau lawm, nws tsis tuaj yeem ua kom loj hauv lub tsheb. Txawm li cas los xij, nws tuaj yeem txiav txim siab los teeb tsa millimeter yoj radar, thiab nws cov nqi qis dua ib xyoos ib zaug.
Nyob rau hauv lub neej yav tom ntej, radar thiab lub koob yees duab kev sib koom tes sensing yuav dhau los ua lub ntsiab; Hais txog kev txiav txim siab- ua, nws xav tau kev tswj hwm algorithm kom paub, yog li nws xav tau ntau qhov chaw nres tsheb cov ntaub ntawv qhia algorithms kom paub txog txoj hauv kev npaj ua ke; Nyob rau hauv cov nqe lus ntawm kev tua, nrog kev txhim kho txuas ntxiv ntawm kev tswj cov cuab yeej siv hluav taws xob, kev ua haujlwm ntawm kev ua tiav yuav ntau dua thiab ntau dua, kev nyab xeeb yuav ntau dua thiab txhim khu kev qha, thiab lub tsheb yuav ntau dua thiab ntau dua rau kev tswj xyuas ntse.
Yog li ntawd, fusion thiab complementarity ntawm ntau sensors yog inevitable. Seb lidar, ultrasonic, millimeter yoj, lub koob yees duab, GPS, IMU, accelerometer thiab gyroscope yog qhov tsim nyog sensors rau kev tsav tsheb tsis siv neeg hluav taws xob.
