Saiti ino inoshandiswa nebhizinesi kana mabhizinesi ane Informa PLC uye ese ane kodzero anogara navo.Hofisi yakanyoreswa yeInforma PLC ndeye 5 Howick Nzvimbo, London SW1P 1WG.Yakanyoreswa muEngland neWales.Nhamba 8860726.
Rohm yakazivisa kuvandudzwa kwemotokari isina waya-yekuchaja mhinduro ine yakabatanidzwa padyo-munda kutaurirana (NFC).Iyo inobatanidza pamwe Rohm's mota-giredhi (AEC-Q100 inokodzera) isina waya simba rekufambisa dhizaini IC (BD57121MUF-M) neSTMicroelectronics 'NFC Reader IC (ST25R3914) uye 8-bit microcontroller (STM8A akatevedzana).
Pamusoro pekuenderana neWPC's Qi standard inotsigira EPP (Wedzera Power Profile), iyo inoita kuti charger iwane kusvika ku15 W yemagetsi, iyo yakawanda-coil dhizaini inonzi inogonesa nzvimbo yekuchaja (2.7X yakakura yekuchaja huwandu unopesana. imwe coil zvigadziriso).Izvi zvinoreva kuti vatengi havafanire kunetseka nezve kunyatso batanidza mafoni avo kunzvimbo yakapihwa yekuchaja kuti vakwanise kuchaja pasina waya.
Qi isina waya yekuchaja yakagamuchirwa neEuropean Automotive Standards Group (CE4A) seyakajairwa yekuchaja mumotokari.Pakazosvika 2025, zvakafanotaurwa kuti mota zhinji dzichange dzakashongedzerwa neQi-based wireless charger.
NFC inopa humbowo hwemushandisi kubvumidza kutaurirana kweBluetooth/Wi-Fi ine infotainment mauniti, kukiya musuwo/kukiinura masisitimu, uye kutanga injini.NFC zvakare inogonesa zvigadziriso zvemotokari zvevatyairi vakati wandei, senge chigaro uye girazi chinzvimbo, infotainment pre-seti, uye mafambiro ekuenda pre-seti.Mukushanda, smartphone inoiswa pane yekuchaja padhi kuti itange otomatiki kugovera skrini neiyo infotainment uye navigation system.
Pakutanga, kana uchibatanidza mafoni kune infotainment masisitimu, zvaive zvakafanira kuita manyorero pairing kune yega yega mudziyo.Nekudaro, nekubatanidza Qi isina waya yekuchaja neNFC kutaurirana, Rohm yaita kuti zvibvire kwete kungochaja nharembozha dzakadai sema smartphones, asiwo kuita Bluetooth kana Wi-Fi pairing panguva imwe chete kuburikidza neNFC chokwadi.
Iyo ST25R3914/3915 mota-giredhi NFC muverengi ICs inoenderana ne ISO14443A/B, ISO15693, FeliCa, uye ISO18092 (NFCIP-1) Active P2P.Ivo vanosanganisira analog yekumberi magumo ine izvo zvinonzi zvakanakisa-mu-kirasi inogamuchira senitivity, kuendesa kunze-chinhu chekuona chiitiko mumotokari centre consoles.Pachiyero cheQi, chinhu chekunze chekuona basa rekuona zvinhu zvesimbi chinosanganisirwa.Izvi zvinodzivirira deformation kana kukuvara kubva pakuitika nekuda kwekunyanya kupisa chizvarwa kana chinhu chesimbi chikaiswa pakati peanotumira uye anogamuchira.
Iyo ST25R3914 inosanganisira ST's proprietary Automatic Antenna Tuning basa.Inochinjika kune yakatenderedza shanduko kudzikisa mhedzisiro kubva kune esimbi zvinhu padhuze nemuverengi antenna, senge makiyi kana mari inoiswa pacentre console.Pamusoro pezvo, MISRA-C: 2012-inoenderana RF middleware iripo, iyo inobatsira vatengi kudzikisa yavo software-kuvandudza kuedza.
Iyo STM8A mota 8-bit MCU yakatevedzana inouya mune akasiyana mapakeji uye saizi yekurangarira.Midziyo ine data yakadzamirwa EEPROMs inopihwa zvakare, kusanganisira maCAN-akashongedzerwa mamodheru ane yakawedzera tembiricha yekushanda yakavimbiswa kusvika ku150°C, ichiita kuti inyatsokodzera zvakasiyana-siyana zvekushandisa zvemotokari.
