ʻO ka wehewehe ʻana o ka hui puʻupuʻu kaʻa:
1. ʻĀpana hana (MCU)
Ua kapa ʻia ʻo MCU "ʻāpana mana micro".Inā makemake nā hana o ka ʻōnaehana uila uila, ʻōnaehana infotainment, ʻōnaehana powertrain, ʻōnaehana neʻe kaʻa a me nā ʻōnaehana ʻē aʻe o ke kaʻa e hana maʻamau, pono kēia ʻano chip hana e hoʻokō ai.I waena o lākou, ʻo ka "auto drive system" kaulana loa ʻaʻole hiki ke hoʻokaʻawale ʻia mai ka chip hana.
2. Semiconductor mana
Hoʻohana nui ʻia ka mana semiconductor i ka ʻōnaehana mana kaʻa, ka ʻōnaehana kukui, ka wahie injection, ka palekana chassis a me nā ʻōnaehana ʻē aʻe, ma waena o nā kaʻa wahie maʻamau e hoʻohana maʻamau ia i nā kahua o ka hoʻomaka ʻana, ka hana mana, ka palekana a pēlā aku;Pono nā kaʻa ikaika hou i ka nui o nā semiconductors mana e hoʻokō i nā pono hoʻololi uila pinepine o nā kaʻa.Eia kekahi, pono nā ʻāpana he nui o nā kaʻa uila i ke kākoʻo o nā semiconductors mana.
3. Nani
ʻO ka ʻenekona kaʻa ka mea hoʻokomo o ka ʻōnaehana kamepiula kaʻa.ʻO kāna hana, ʻo ia ka hoʻololi ʻana i nā ʻike ʻano hana like ʻole i ka wā o ka hana kaʻa, e like me ka wikiwiki o ke kaʻa, ka mahana o nā ʻano media like ʻole, ke kūlana hana ʻenehana, a me nā mea ʻē aʻe, i mau hōʻailona uila a hoʻouna iā lākou i ke kamepiula, no laila ʻoi aku ka maikaʻi o ke kaʻa. kūlana.No ka laʻana, ka mea ʻike oxygen, ka mīkini paʻi paʻi paʻi, ka ʻike wela o ka wai, ka ʻenekona hoʻokele pedal position sensor, etc.
No laila, i ka hōʻuluʻuluʻana, he mea nui loa nā'āpana kaʻa no ke kaʻa.Ma waena o nā ʻano ʻekolu o nā ʻāpana hana, nā semiconductors mana a me nā mea ʻike, loaʻa nā mea ʻike i ka māhele mākeke liʻiliʻi loa.Akā inā ʻaʻohe mea ʻike, ʻaʻole hiki i nā kaʻa ke hehi i ka accelerator.I kēia manawa ke manaʻoʻiʻo nei au ua maopopo mākou i ke kumu ʻaʻole hiki ke kūkulu ʻia nā kaʻa me ka ʻole o nā chips.
ʻEhia mau ʻāpana e pono ai ke kaʻa?
I ka wā ma mua, lawe ʻo ia ma kahi o 500-600 chips e hana i kahi kaʻa maʻamau.Akā me ka ulu mau ʻana o ka ʻoihana kaʻa, huli mālie nā kaʻa o kēia lā mai ka mīkini a i ka uila.ʻOi aku ka naʻauao o nā kaʻa, no laila e ʻoi aku ka nui o nā chips e pono ai.Ua hoʻomaopopo ʻia ʻo ka helu awelika o nā chips i koi ʻia no kēlā me kēia kaʻa ma 2021 ua hiki aku ma mua o 1000.
Ma waho aʻe o nā kaʻa kuʻuna, ʻo nā kaʻa ikaika hou ka "ʻohana nui" o nā chips.Pono kēlā mau kaʻa i ka nui o nā mea hoʻohuli DC-AC, nā mea hoʻololi, nā mea hoʻololi a me nā mea ʻē aʻe, a ua hoʻonui nui ʻia ke koi no IGBT, MOSFET, diodes a me nā mea semiconductor ʻē aʻe.No laila, ʻoi aku ka maikaʻi o kahi kaʻa ikehu hou e pono ai ma kahi o 2000 chips, he mea kupanaha loa.
