Nekuti Ethernet yakagadzirwa kare kare, kufambisa kweruzivo rwenguva chaiyo hakuna kutariswa.Nehuwandu hukuru hwevaraidzo yeaudio nemavhidhiyo inopinda mucockpit, huwandu hweECU uye kudiwa kwesimba remakomputa reECUs zvakaratidza kukura kunoputika, izvo zviri pachena munguva yeADAS uye iri kuuya yekusatyaira nguva, uye kudiwa kwekombuta bandwidth. kwatangawo kuputika.Izvi zvakakonzera kuwedzera kukuru kwemutengo wemagetsi emagetsi masisitimu, kune rumwe rutivi, kuwedzera kwenhamba uye kunaka kweECU masisitimu, nekuda kwekugoverwa komputa, nhamba huru yemakomputa zviwanikwa zvakaparara, uye isu tiri kutaura nezvemotokari. Ethernet uchishandisa peya imwe chete yetambo dzisina kuvharidzirwa uye zvidiki uye zvakanyanya compact zvibatanidza, uchishandisa isina kuchinjika yakamonyoroka peya inogona kutsigira 15m kutapurirana kureba (kune nhovo yakamonyoroka peya inogona kutsigira 40m), iyi optimization kugadzirisa inoita mota Ethernet inogona kusangana nemotokari EMC zvinodiwa.Kuderedza mutengo wekubatanidza mumotokari kusvika pa80% uye huremu hwewaya mumotokari hunosvika 30%, PHY ye100M Automotive Ethernet inotora tekinoroji ye1G Ethernet kuti igone kugonesa nzira mbiri kutaurirana pavaviri nekushandisa echo kudzima.Conventional PoE yakagadzirirwa Ethernet ine 4 peya dzetambo, saka PoDL yakagadziridzwa yakanangana nemotokari Ethernet kuti ipe 12VDC kana 5VDC yemagetsi emagetsi ekushanda kwakajairika kweECU yemagetsi control unit patambo imwe chete.Ehezve, kudiwa kwebandwidth zvakare chinhu, uye akasiyana masensa, kunyanya lidar uye yakakwirira-resolution makamera, anofanirwa kutumira data uchishandisa Ethernet.
Automotive Ethernet tekinoroji yepeer-to-peer umo imwe neimwe node yemagetsi inobatanidzwa sequentially.Switch inoiswa musystem inobatsira kumisikidza kutaurirana pakati peECU dzakawanda uye nzira traffic kune akasiyana mamwe mayuniti munetiweki.IEEE inomisa tekinoroji kuburikidza ne100BASE-T1 uye 1000BASE-T1 mota-muridzi Ethernet zviyero.Mukana wakakosha wemotokari Ethernet ndeyekuti inodhura-inoshanda kupfuura mamwe maprotocol.Zvizvarwa zvakapfuura senge CAN inongopa 10Mb/s throughput, nepo mota Ethernet inogona kupa yakakosha kutaurirana mwero we100Mb/s kubva pakutanga.Kuenzaniswa neyechinyakare tambo harnesses, mota Ethernet inoshandisa Ultra-yakareruka uye inoshanda cabling kuchengetedza nzvimbo, kuderedza mitengo, uye kuderedza kuoma.
