Thaum nws los txog rau lub pas nrig hloov pauv, peb yuav tsum tham txog kev txhim kho sai ntawm cov pas nrig hloov pauv hluav taws xob, lwm hom pas nrig hloov pauv, lwm cov lus piav qhia ntxaws.
Tam sim no muaj plaub hom shifters hauv kev ua lag luam. Los ntawm keeb kwm ntawm kev txhim kho, lawv yog: MT (ManualTransmissionShifter, tes hloov lever) - > AT (AutomaticTransmissionTransmissionShifter, Automatic gear lever) rau AMT (AutomatedMechanicalTransmissionShifter, semi-automatic gear lever), GSM (GearShiftModule, lossis SBW = ShiftByWire, electronic gear lever)
Vim tias tus pas hloov ntawm MT thiab AT yog ib qho qauv kho tshuab xwb, nws tsis muaj kev sib raug zoo nrog tus pas hloov hluav taws xob. Yog li ntawd, raws li tau piav qhia thaum pib, lwm kem tau tsim.
Ua ntej peb tham txog lub electronic shift lever, cia peb tham txog lub AMT shift lever.
Lub iav AMT tsis yog tsuas yog txais cov qauv kho tshuab ntawm MT/AT zoo meej xwb, tab sis kuj siv electromagnetic induction los txheeb xyuas qhov chaw iav lossis tsis txheeb xyuas lawv, thiab tsuas yog tso tawm cov cim ntawm qhov chaw iav sib txawv. Hais yooj yim, lub iav AMT lossis nws cov khoom sib txuas yog nruab nrog cov hlau nplaum nrog cov ncej zoo thiab tsis zoo nyob rau sab qaum teb thiab sab qab teb, thiab hloov nws txoj haujlwm los ntawm cov iav sib txawv. Lub hauv paus board (PCB) nruab nrog SENSOR IC ntawm AMT shift lever tsim cov hlau nplaum induction rau cov hlau nplaum hauv ntau qhov chaw thiab tso tawm cov hluav taws xob sib txawv. Lub tsheb processor module yuav hloov cov iav sib xws rau cov hluav taws xob sib txawv lossis cov cim.
Los ntawm qhov kev xav ntawm cov qauv, AMT shift rod nyuaj dua li MT/AT shift rod, thev naus laus zis nce siab, tus nqi ntawm ib chav tsev kim dua, tab sis rau lub tsheb OEM, kev siv AMT shift rod, tsuav yog kev hloov pauv me me, uas yog, feem ntau tuaj yeem siv lub zog ntawm MT, yog li tus nqi tag nrho ntawm lub tsheb yuav qis dua.
Vim li cas ho siv lub zog hloov AMT? Yog vim tias lub zog hloov hluav taws xob kuj siv lub hauv paus ntsiab lus ntawm kev siv hluav taws xob ntawm lub zog hloov AMT los hloov cov iav.
Txawm li cas los xij, muaj qhov sib txawv ntawm kev muaj Micro-CPU ntawm lub substrate thiab tsis muaj ib qho.
Yog tias lub substrate (PCB) muaj Micro-CPU, nws yuav cais cov tam sim no sib txawv, paub meej tias nws cov iav sib xws, thiab xa cov ntaub ntawv ntawm cov iav sib xws mus rau lub tsheb ECU hauv hom kev sib kis tshwj xeeb (xws li CAN teeb liab). Cov ntaub ntawv tau txais los ntawm cov ECUs sib xws (piv txwv li TCM, TransmissionControl) thiab kev sib kis tau qhia kom hloov. Yog tias tsis muaj Micro-CPU ntawm lub hauv paus (PCB), lub lever hloov hluav taws xob nws tus kheej yuav raug xa mus rau lub tsheb ECU los ntawm cov teeb liab xaim kom hloov iav.
Nws tuaj yeem hais tias kev siv AMT shift bar yog kev sib haum xeeb ntawm lub tsheb OEM rau cov nqi tsim tsheb pheej yig, uas muaj ob qho tib si qhov loj ntawm MT / AT shift bar thiab kev xaiv ntawm electromagnetic induction. Txawm li cas los xij, kev xaiv ntawm hluav taws xob shift bar tsis txwv los ntawm qhov loj me, yog li lub hluav taws xob shift bar tam sim no tau tsim nrog lub hom phiaj ntawm miniaturization ua lub hauv paus. Yog li ntawd, ntau qhov chaw tuaj yeem tso rau hauv lub tsheb tsim. Tsis tas li ntawd, cov kev teeb tsa xws li shift rod Stroke thiab Operation Force kuj tuaj yeem ua kom zoo dua piv rau lub tshuab hloov pauv rod, ua rau kev ua haujlwm yooj yim dua rau tus tsav tsheb.
Tam sim no, cov hom hluav taws xob Lever hauv kev ua lag luam yog raws li nram no: Lever Hom, Rotary/Dial Hom, Push Switch Hom, Column Lever Hom.
Piv txwv li, siv lub pob qhov rooj, nws tuaj yeem rov qab mus rau P iav thiab xauv los ntawm BTSI (BRAKING TRANSMISSION SHIFT INTERLOCK) lossis nqa nws tus kheej. Hauv lub tsheb, lub bar nres muaj qhov program loj heev, txwv tsis pub nws tsuas yog qhia txog ntau yam yuam kev, yog li nws yuav tsum tau txhuam software debug. Lub ceg qaib BMW ncaj kuj muaj lub luag haujlwm tig rov qab mus rau P iav tom qab tua hluav taws.
Txij thaum pib ntawm qhov loj thiab loj ntawm lub tshuab hloov pauv, mus rau kev tsim cov khoom siv hloov pauv me me, sib dua nrog nws tus kheej qhov kev pab cuam, tau ua tiav zoo heev ntawm qhov siab thiab siab, tab sis tsis tuaj yeem hais tias kev siv cov khoom siv hloov pauv hluav taws xob yuav yog lwm lub tsheb tus nqi qis dua, tab sis yuav nce siab, yog li OEM tam sim no tseem yog cov khoom siv hloov pauv hluav taws xob. Tab sis nrog kev nce ntxiv ntawm cov tsheb fais fab tshiab, nws tuaj yeem kwv yees tau tias cov khoom siv hloov pauv hluav taws xob yuav maj mam dhau los ua lub hauv paus tseem ceeb yav tom ntej.
