ADAS PCB ni iki? Ingero z'ikoreshwa n'ibipimo by'ibishushanyo

Sisitemu zo gufasha abashoferi zigezweho (ADAS) zirimo guhindura urwego rw'imodoka binyuze mu kunoza umutekano w'ibinyabiziga no kugira uburambe mu gutwara. Ishingiro ry'izi sisitemu ni igice cy'ingenzi—ADAS PCBs (Ibibaho byacapwe).

ADAS PCB ni iki?

ADAS PCB ni urubuga rwakozwe mu buryo bwihariye rukoreshwa mu bikoresho by'ikoranabuhanga by'imodoka kugira ngo rushyigikire gutunganya amakuru mu buryo bwihuse uhereye ku byuma bipima nka kamera, radar, LiDAR, na sisitemu za ultrasonic. Izi PCB zisaba kwizerwa cyane, kudashyuha cyane, no guhuza ingufu za electromagnetic kugira ngo zikore mu binyabiziga bikomeye.

Imikoreshereze y'ingenzi ya ADAS PCBs

ADAS PCB zikoreshwa cyane muri izi porogaramu zikurikira:

• Umuburo wo kugongana imbere (FCW): Ikoresha amakuru ya radar na kamera kugira ngo imenye inzitizi kandi imenyeshe umushoferi.
• Umuburo wo kuva mu muhanda (LDW): Itunganya amakuru agaragara kugira ngo imenye niba imodoka irimo guhindukira ikava mu muhanda wayo.
• Uburyo bwo kugenzura ingendo zo mu bwato bushobora kwihuta (ACC): Ibungabunga intera itekanye ikoresheje uburyo bwo gusubiza amakuru mu gihe nyacyo.
• Gupima Utudomo tw'Abatabona (BSD): Ihuza radar yo ku ruhande na sensor za ultrasound kugira ngo imenye imodoka ziri hafi aho.
• Gufunga feri mu buryo bwikora (AEB): Bitera feri iyo hagaragaye impanuka iri hafi kugongana.

Ibitekerezo ku gishushanyo mbonera cya ADAS PCB

Mu gushushanya PCB za sisitemu za ADAS, hari ibintu byinshi by'ingenzi bigomba kwitabwaho:

• Ubuziranenge bw'amajwi yihuta cyane: Kubera ko amakuru ya radar na kamera akeneye kohereza amakuru vuba, impedance igenzurwa n'igihombo gito ni ngombwa.
• Imicungire y'ubushyuhe: Moduli za ADAS zikoresha ingufu nyinshi zitanga ubushyuhe bwinshi; ibikoresho nk'inkingi y'icyuma cyangwa substrate za ceramic bishobora gukoreshwa.
• Gushyira hamwe kw'ibice byinshi: Sisitemu zikomeye za ADAS zikunze gusaba PCB zifite urwego rwa 8-12 kugira ngo zinyure neza urwego rw'amashanyarazi, ubutaka, n'ibimenyetso.
• Kugenzura EMI/EMC: Uburyo bwo kurinda no gufunga neza ni ingenzi cyane kugira ngo hirindwe ko ibimenyetso bibangamira inzira.
• Kwizerwa mu bihe bikomeye: PCB zigomba kwihanganira guhindagura, ubushuhe, n'ihindagurika ry'ubushyuhe mu bidukikije by'imodoka.

Uko gutwara imodoka mu buryo bwikora no kugenda neza bigenda bitera imbere, ADAS PCB zigenda zirushaho gutera imbere no kuba ingenzi. Guhitamo umufatanyabikorwa ukwiye mu gushushanya PCB ufite ubuhanga mu gukora amabati y’imodoka akoreshwa inshuro nyinshi kandi yizewe cyane ni ingenzi kugira ngo umuntu agire icyo ageraho.
