Radar

Amakuru yimpanuka yerekana ko impanuka zirenga 76% ziterwa namakosa yabantu gusa;no muri 94% byimpanuka, amakosa yabantu arimo.ADAS (Advanced Driver Assistance Systems) ifite ibyuma bifata ibyuma byinshi bya radar, bishobora gushyigikira neza ibikorwa rusange byo gutwara abantu.Birumvikana ko ari ngombwa gusobanura hano, RADAR yitwa Radio Detection And Ranging, ikoresha imirongo ya radio kugirango ibone kandi ibone ibintu.

Sisitemu ya radar isanzwe ikoresha 24 GHz cyangwa 77 GHz ikora.Ibyiza bya 77GHz biri murwego rwo hejuru rwukuri rwo gupima no kwihuta, icyerekezo cyiza cya horizontal, hamwe na antenne ntoya, kandi hariho ibimenyetso bike bivanga.

Imirasire ngufi ikoreshwa muburyo bwo gusimbuza ultrasonic sensor no gushyigikira urwego rwo hejuru rwo gutwara ibinyabiziga.Kugira ngo ibyo bishoboke, ibyuma bizashyirwa mu mpande zose z’imodoka, kandi hazashyirwaho sensor-ireba imbere kugirango ibone intera ndende izashyirwa imbere yimodoka.Muri sisitemu ya 360 ° yuzuye ya radar yumubiri wikinyabiziga, hazashyirwaho ibyuma byiyongera hagati yimpande zombi zumubiri.

Byiza, ibyuma bya radar bizakoresha umurongo wa 79GHz hamwe na 4Ghz yohereza.Nyamara, ibipimo byerekana ibimenyetso byogukwirakwiza kwisi yose byemerera gusa 1GHz umurongo mugari wa 77GHz.Muri iki gihe, ubusobanuro bwibanze bwa radar MMIC (monolithic microwave integrated circuit) ni "imiyoboro 3 yohereza (TX) naho imiyoboro 4 yakira (RX) ihuriweho numuzunguruko umwe".

Sisitemu yo gufasha abashoferi ishobora kwemeza L3 no hejuru yimikorere idafite abapilote bisaba byibura sisitemu eshatu: kamera, radar na laser detection.Hagomba kubaho ibyuma byinshi bya buri bwoko, bigabanijwe mumwanya utandukanye wimodoka, kandi bigakorera hamwe.Nubwo tekinoroji ya semiconductor ikenewe hamwe na kamera hamwe na tekinoroji ya radar sensor yiterambere iraboneka, iterambere rya sisitemu ya lidar iracyari ikibazo gikomeye kandi kidahungabana mubijyanye na tekiniki nubucuruzi.
