Txheej txheem cej luam ntawm tsheb wireless txuas khoom
Automotive wireless connectivity khoom yog tsim los siv technologies xws li Bluetooth, Wi-Fi, UWB, thiab 5G/V2X (tsheb thauj mus los-rau-Txhua yam) los pab txhawb nyob rau hauv - tsheb sib cuam tshuam thiab kev sib txuas nyob rau hauv cov xwm txheej ceev ceev. Ua haujlwm raws li qhov tseem ceeb ntawm cov khoom siv hauv tsheb ntse, cov khoom siv no hloov cov kev daws teeb meem ib txwm muaj thiab kov yeej cov kev txwv lub cev ntawm cov ntaub ntawv xa mus, xa cov kev sib tw, kev tsav tsheb thiab caij tsheb.
Raws li cov khoom siv hluav taws xob txuas hluav taws xob siv dav dav tshaj plaws, hauv - tsheb wireless chargers feem ntau poob rau hauv peb pawg: cua qhov cua-mounted, nruab nrab console-mounted (adhesive), thiab armrest-embedded. Siv tus qauv Qi wireless charging, lawv siv cov khoom siv mobile xws li smartphones, tshem tawm cov teeb meem xws li cluttered hauv - tsheb thaiv thiab hnav thiab tsim kua muag ntawm cov chaw nres nkoj xaim. Cov qauv siab-kawg tam sim no suav nrog cov yam ntxwv zoo li NFC nrawm-pairing, siab- lub zog them ceev (15W–50W), tiv thaiv kev kub dhau / overvoltage thiab cov khoom txawv teb chaws nrhiav pom, thiab tsis siv neeg clamping thiab sib dhos. Lawv tau sib xws nrog ntau lub npe ntawm lub xov tooj smartphones, thiab qee cov qauv txhawb kev sib koom ua ke ntawm lub tsheb, tso cai rau cov khoom siv synchronized ntawm cov khoom siv roj teeb uas tseem tshuav.
Lwm cov khoom lag luam tseem ceeb hauv tsheb sib txuas wireless.
Tsim los rau cov tsheb sib tsoo hauv tsheb thiab cov qauv qub uas tsis muaj lub peev xwm hauv CarPlay lossis HiCar, cov wireless adapters hloov wired hauv - tsheb sib txuas rau hauv cov wireless. Thaum nkag mus rau hauv lub tsheb, lub xov tooj smartphone yuav txuas nrog lub infotainment system- tshem tawm qhov xav tau los ntsaws rau hauv cov cables- thiab ua haujlwm wireless ntawm cov haujlwm xws li kev taw qhia kev taw qhia, suab paj nruag playback, tswj lub suab, thiab tes- hu dawb. Cov khoom no feem ntau txhawb nqa Android thiab iOS platforms thiab OTA (Tshaj -- Cua) hloov tshiab; tau tshaj 90% ntawm cov qauv tsheb thaum xub thawj nruab nrog wired connectivity, lawv txo tus nqi rau cov neeg siv hloov mus rau lub wireless system.
Cov khoom no feem ntau yog siv los ntxiv cov peev xwm txuas wireless rau cov qauv tsheb qub thiab feem ntau tuaj hauv ob hom: hauv - tsheb txais Bluetooth thiab Bluetooth FM transmitters. Los ntawm kev txuas mus rau lub tsheb qhov chaw nres nkoj AUX lossis lub qhov hluav taws xob lub qhov hluav taws xob, lawv ua kom muaj kev sib txuas ntawm lub xov tooj wireless rau cov laus lub tshuab uas tsis muaj kev txhawb nqa Bluetooth, tso cai rau tes- hu dawb thiab ua suab paj nruag. Qee cov qauv kuj suav nrog cov yam ntxwv xws li USB drive playback, lub suab pab ua kom, thiab ceev- them cov zis tawm, muab cov tswv tsheb tus nqi- txoj hauv kev zoo los txhim kho lawv cov tsheb qub nrog cov cuab yeej ntse. Hauv - tsheb wireless Wi-Fi routers-feem ntau hu ua mobile hotspots rau tsheb-hloov cov xov tooj ntawm tes rau hauv Wi-Fi teeb liab thaum cov ntaub ntawv SIM tau muab tso rau. Qhov no ua rau ntau tus neeg caij tsheb sib txuas cov khoom siv xws li smartphones, ntsiav tshuaj, thiab laptops rau hauv internet, txaus siab rau kev lom zem thiab ua haujlwm thaum mus ntev - mus deb. Cov khoom lag luam tseem ceeb tam sim no txhawb 5G tes hauj lwm nrog gigabit- theem siab ceev thiab ib txhij ntau- khoom sib txuas; lawv tau sib xws nrog ntau lub tsheb fais fab, xws li cov khoom siv luam yeeb lossis OBD chaw nres nkoj. Tsis tas li ntawd, wireless digital keys raws li UWB thev naus laus zis tau tshwm sim los ua ib yam tshiab ntawm cov khoom siv tsheb sib txuas wireless. Cov kev txhawb nqa no zoo li tsis siv neeg xauv thaum mus kom ze, tsis siv neeg kaw thaum tawm mus, thiab qhov chaw tso ncaj tsis muaj cov ntsiab lus thauj tog rau nkoj. Qee cov khoom lag luam tseem tso cai rau kev nkag mus rau qhov tseem ceeb ntawm ntau tus neeg siv, ua qhov hloov pauv rau lub cev cov yuam sij kom muaj kev paub tsis meej tag nrho rau lub tsheb nkag thiab hluav taws xob.
Qhov zoo thiab kev loj hlob zeem muag ntawm kev sib txuas wireless hauv tsheb.
Piv nrog rau cov kev daws teeb meem kev sib txuas ib txwm siv, cov khoom siv hluav taws xob wireless txuas tau muaj txiaj ntsig zoo. Ua ntej, lawv ua kom zoo dua hauv - lub tsheb qhov chaw, tshem tawm cov ntaub ntawv tsis sib haum xeeb, ua kom lub tsheb nruab nrab ntawm lub console zoo dua, thiab txo qhov kev pheej hmoo ntawm kev ua haujlwm tsis zoo uas tshwm sim los ntawm cable hnav thiab xoob cuam tshuam. Qhov thib ob, cov txheej txheem ua haujlwm yooj yim dua. Cov khoom lag luam feem ntau txhawb kev sib koom ua ke tsis siv neeg tom qab tus neeg siv nkag mus rau hauv lub tsheb, tshem tawm qhov xav tau ntawm phau ntawv ntsaws thiab tshem tawm txhua lub sijhawm, uas haum rau cov neeg siv cov cwj pwm ntawm kev sib cais ntawm kev mus ncig. Thib peb, kev sib raug zoo yog zoo heev. Cov khoom lag luam feem ntau txhawb nqa rov qab ua dua tom qab lub tsheb tawm ntawm lub Hoobkas, uas tsis tas yuav loj - hloov pauv ntawm lub tsheb qub Circuit Court, ua rau cov qauv qub kom tau txais kev paub wireless ntse nrog kev ua haujlwm zoo heev.
Nrog rau qhov muaj koob meej ntawm cov tsheb ntse, cov khoom siv hluav taws xob wireless txuas txuas ntxiv txuas ntxiv txhim kho nyob rau hauv cov kev taw qhia ntawm cov ntaub ntawv ntau dua, qis zog siv thiab kev ruaj ntseg dua. Nyob rau hauv lub neej yav tom ntej, lawv yuav ntxiv kev koom ua ke rau hauv lub ntse cockpit ecosystem thiab dhau los ua tus choj txuas txuas rau cov neeg siv khoom siv hluav taws xob thiab hauv - lub tshuab tsheb, txhawm rau coj cov neeg siv kev mus ncig zoo dua thiab tsis sib haum xeeb.
