MEMS IMU ya Tshebetso e Phahameng: The Next Trend in Autonomous Driving

Lefapheng le ntseng le tsoela pele ka potlako la ho khanna ka boithaopo, tekanyo ea tekanyo ea inertial (IMU) e fetohile karolo ea bohlokoa le mokhoa oa ho qetela oa tšireletso bakeng sa tsamaiso ea boemo. Sengoliloeng sena se hlahloba melemo ea li-IMU ho khanna ka boithaopo, lits'ebetso tsa bona, le 'maraka o hlahang oa li-IMU tse sebetsang hantle haholo tsa microelectromechanical system (MEMS).

Utloisisa IMU

The inertial measurement unit (IMU) ke sesebelisoa se rarahaneng se kopanyang accelerometer, gyroscope, 'me ka linako tse ling magnetometer ho lekanya matla a itseng, lebelo la angular, le matla a khoheli ho potoloha koloi. Ka ho kopanya litekanyo tsena ha nako e ntse e ea, li-IMU li ka fana ka tlhahisoleseding e nepahetseng mabapi le boemo ba koloi, tataiso le lebelo. Bokhoni bona bo bohlokoa bakeng sa likoloi tse ikemetseng, tse itšetlehileng ka lintlha tse nepahetseng tsa boemo ba ho tsamaea ka mokhoa o sireletsehileng tikolohong e rarahaneng.

Tšebeliso le phello ea IMU ho khanna ka boithaopo

Lisebelisoa tsa IMU ho khanna ka boithaopo li ngata. Li phetha karolo ea bohlokoa ho ntlafatseng ho tšepahala le ho nepahala ha litsamaiso tsa ho beha maemo, haholo-holo maemong ao mats'oao a GPS a ka bang fokola kapa a sa fumanehe, joalo ka likotopong tsa litoropo kapa lithanele. Maemong ana, IMU e sebetsa e le sesebelisoa se matla sa ho boloka, ho netefatsa hore koloi e ka tsoela pele ho sebetsa ka mokhoa o sireletsehileng le ka katleho.

Ho feta moo, li-IMU li kenya letsoho ts'ebetsong ea kakaretso ea sensor fusion, moo lintlha tse tsoang ho li-sensor tse fapaneng tse kang lidar, lik'hamera le radar li kopantsoe ho fumana kutloisiso e pharaletseng ea tikoloho e potolohileng koloi. Ka ho fana ka lintlha tsa nako ea sebele mabapi le motsamao oa likoloi, li-IMU li thusa ho ntlafatsa ho nepahala ha li-algorithms tsa sensor fusion, ka hona ho ntlafatsa bokhoni ba ho etsa liqeto le ho tsamaisa.

Tšusumetso ea IMU e feta ho beha maemo. Li matlafatsa botsitso le taolo ea koloi, li etsa hore lebelo, braking le likhutlo li be bonolo. Sena ke sa bohlokoa haholo bakeng sa ho khanna ka boithaopo, moo ho boloka boiketlo le polokeho ea bapalami ho leng bohlokoa. Li-IMU tsa MEMS tse sebetsang hantle haholo, li eketsa kutlo le ho fokotsa lerata, li etsa hore e be tse loketseng ho fihlela litlhoko tse thata tsa likoloi tse ikemetseng.

Mmaraka o matla oa IMU oa ho khanna o ikemetseng

Mmaraka oa IMU oa ho khanna o ikemetseng o ntse o hola haholo. Ha indasteri ea likoloi e fetohela ho motlakase le ho iketsetsa, tlhokahalo ea mahlale a tsoetseng pele a sensor, ho kenyelletsa le ts'ebetso e phahameng.MEMS IMUs, e tsoela pele ho hōla. Ho latela litlaleho tsa indasteri, 'maraka oa lefats'e oa li-IMU lits'ebetsong tsa likoloi o lebelletsoe ho fihla ho libilione tsa lidolara lilemong tse' maloa tse tlang, o susumetsoa ke ho ata ha theknoloji ea ho khanna e ikemetseng.

Lintlha tse 'maloa li tlatsetsa ponong ena e matla ea' maraka. Taba ea pele, ts'ebetso ea likarolo tse ntlafalitsoeng tsa polokeho ea koloi e khothalelitse bahlahisi ho tsetela haholo lits'ebetsong tsa sensor tse tsoetseng pele. Li-IMU ke karolo ea bohlokoa ea litsamaiso tsena hobane li fana ka lintlha tse nepahetseng tsa motsamao. Taba ea bobeli, thahasello e ntseng e hola ea litoropo tse bohlale le likoloi tse hokahaneng e ntse e tsoela pele ho khanna tlhoko ea theknoloji e tšepahalang ea ho beha maemo. Ha tikoloho ea litoropo e ntse e rarahana le ho feta, tlhoko ea litharollo tse nepahetseng tsa ho tsamaea e ba bohlokoa le ho feta.

Ka bokhutšoanyane, MEMS IMU ea ts'ebetso e phahameng e lebelletsoe ho ba mokhoa o latelang oa ho khanna ka boithaopo. Melemo ea bona sebakeng sa sebaka, botsitso le fusion ea sensor li etsa hore e be tsa bohlokoa bakeng sa ts'ebetso e bolokehileng le e sebetsang ea likoloi tse ikemetseng. Ha mmaraka oa theknoloji ena o ntse o tsoela pele ho hola, karolo ea IMU e tla bonahala haholoanyane, e tiisa boemo ba eona e le lejoe la motheo la tikoloho ea ho khanna e ikemetseng.
