Ibisobanuro muri make byerekeranye no gukoresha sensor mu binyabiziga byigenga

Vuba aha, imodoka yo kwikorera ni ingingo ishyushye, kandi raporo zijyanye nayo ntisanzwe.Amasosiyete amwe nka BMW, Benz yari yaranashyize ahagaragara moderi yambere yimodoka yigenga.Kubwoko butandukanye no gukoresha imodoka, hariho sensor zidasanzwe nkaKIA Auto SPEED sensor, VW Oxygene Sensor na TOYOTA Air Flow Sensor.Kwikorera wenyine ntabwo bisa nkibihimbano kuri twe.

Kugirango imodoka zimenye gutwara, ikintu cya mbere cyo gukemura nikibazo cyo kuzamura umutekano.Nigice kinini gikeneye gushorwa mubikorwa bya R&D.Imodoka igomba kuba ifite "amaso" ifite icyerekezo cyiza hamwe n "ubwonko" bwiza cyane kugirango umutekano ubeho.Kandi "amaso" ni ubwoko bwa sensor zose hamwe nibikoresho byo gupima robine.

Ubwoko bwa sensors mumodoka yigenga

Rukuruzi ni Kamera, Lidar, Radar, IMU na Ultrasonic radar muri sensor yigenga.Ibikurikira, reka tumenye ibyo byuma bikurikirana.

Kamera

Kamera ni imwe muriubwoko bwimbitse kandi bwamamaye cyane, ntabwo bukoreshwa mumodoka yigenga.Ibyamamare bya kamera nibindi bikorwa bifasha abashakashatsi gutanga tekinoroji nyinshi zifasha.Na none, hari tekinoroji ifasha yatunganijwe mubindiimirima hamwe nibikorwa byamasoko.Imodoka zombi zigenga kandi zitigenga zikoresha kamera nyinshi, zirimo imbere, inyuma, uruhande rwagutse.Rero, tekinoroji ya kamera yakoreshejwe neza mubikorwa byimodoka.Imbaraga za kamera zibitswe na kamera yihariye yigitugu are igiciro giton'ikoranabuhanga rirakuze, kuko hariho abantu benshi bakora algorithm hamwe na kamera.Intege nke nuko kamera igarukira kumucyo wibidukikije kuburyo bugereranije kandi biragoye cyane kubona amakuru yukuri yibice bitatu (Kamera ya Monocular ntibishoboka, kandi kamera ya binocular cyangwa ocular-ocular nayo yatanzwe).

Gukemura

Ugereranije na kamera, Lidar ningirakamaro kumodoka yigenga.Laser radar izwi kandi nka optique radar, bidatinze yitwa Lidar.Radar ya lazeri ni ukugera ku ntego yo kohereza urumuri rwa lazeri, kumenya neza kwayo ni hejuru, urwego rwo kumenya ni rugari.Ariko, ibibi bya lidar nabyo biragaragara.Lidar irashobora kwibasirwa n’imvura n’imvura ya shelegi mu kirere, kandi igiciro cyayo nacyo ni impamvu nyamukuru ibuza ikoreshwa.

Ku giti cyanjye, impamvu yingenzi ituma lidar ifatwa nkimwe mu byuma byifashishwa mu gutwara ibinyabiziga byigenga ni akarusho kayo mu kubaka imiterere y’ibidukikije bitatu.Radar ya laser yohereza imirongo myinshi ya laser kugirango ikusanyirize hamwe amakuru yibidukikije ahantu hirengeye, kandi binyuze mubikoresho byayo bizunguruka, amakuru akusanyirizwa murwego rwa dogere 360 ​​muburyo butambitse.Igikoresho cyakira ibimenyetso kuri lidar kirashobora gufata imirasire ya laser igaragarira kumugambi hanyuma ikayihindura ibicu.Mugutunganya ingingo yibicu, irashobora kurangiza gutondeka no kumenyekanisha ibidukikije.Ariko, buri kintu gifite ibyiza n'ibibi.Nibindi byinshi-bifunze-lidar irashobora gutahura ubunini bwibidukikije, niko umubare munini wibicu byakirwa, hamwe nibisabwa kugirango ibikoresho bikwiranye nubushobozi bwo gutunganya amakuru.Byongeye kandi, nkuko igikoresho kizunguruka imbere ya lidar ikeneye guhora kizunguruka no gusohora imirasire ya laser, ibyuma bifite salmosan azamethiphos yujuje ubuziranenge kugirango bishoboke kwihanganira kwambara kandi neza, ibyo bikaba biganisha ku giciro kinini cya lidar bityo bikazamura igiciro cyibinyabiziga byigenga. .Nyamara, uko ikoranabuhanga ritera imbere, byizerwa ko igiciro nubunini bwa lidar bizagabanuka cyane, mugihe imikorere izanozwa cyane.

Ultrasonic radar

Ultrasonic radar ni sensor igereranijwe.Hariho ubwoko bubiri bwa radar ya ultrasonic.Iya mbere yashyizwe kumatara yimbere ninyuma yimodoka, ikoreshwa mugupima inzitizi zinyuma ninyuma yimodoka.Iyi radar yitwa UPA mu nganda.Ubwoko bwa kabiri, buzwi mu nganda nka APA, ni radar ya ultrasonic yashyizwe kuruhande rwimodoka kugirango ipime intera inzitizi kuruhande.Ikimenyetso cyo kumenya hamwe n'akarere ka UPA na APA biratandukanye.Intera yo kumenya UPA muri rusange iri hagati ya 15-250cm, ikoreshwa cyane cyane ku mbogamizi ziri imbere ninyuma yimodoka, iya APA ni 30-500cm.Urutonde rwo kumenya APA ni rugari, kandi ikiguzi ni kinini.

Impamvu navuze ko radar ya ultrasonic ari sensor idakurikiranwa ni uko ishobora gukora ibindi byinshi usibye kumenya inzitizi nko guhagarara aho imodoka zihagarara no gufashwa byihuse.

Akamaro ka sensors mumodoka yigenga

Hamwe nihuta ryiterambere ryiterambere rigezweho nko gutwara ibinyabiziga byigenga, akamaro nigipimo cyinjira muri sensor nacyo cyakomeje kunozwa.Umubare munini wimodoka yigenga igomba kwishingikiriza kumikoreshereze yubwoko butandukanye bwa sensor kugirango tumenye amashusho atandukanye, akaba aribwo shingiro ryibanze ryo gukora neza numutekano wimodoka.Kubwibyo, mumajyambere yihuse yumurima wo gutwara ibinyabiziga byigenga, akamaro ka sensor karushijeho kugaragara.Ntagushidikanya ko gutwara ibinyabiziga bizaba imwe munganda zingenzi mugihe kizaza, kandi ingano yisoko irashobora gutekerezwa.Uhereye kuriyi ngingo, ubushobozi bwisoko rya kazoza ka sensor nayo izaba nini cyane.

Incamake

Twari tuzi imikoreshereze nakamaro ka sensor zitandukanye kumodoka yigenga.YASEN ni isoko ryiza ryo gutanga sensor.Itanga ubwoko bwubwoko bwose bwimodoka zitandukanye nka sensor ya KIA Auto SPEED sensor.Inyungu iyo ari yo yose, urashobora kuyitabaza.
