He aha ka automotive microwave radar
ʻO ka automotive microwave radar he ʻōnaehana radar e hoʻohana ana i nā microwaves no ka ʻike, hoʻohana nui ʻia i nā kaʻa a me nā kaʻa kaʻa ʻē aʻe. ʻIke ʻo Microwave radar i nā mea i ke kaiapuni a puni ma o ka hoʻouna ʻana a me ka loaʻa ʻana o nā hōʻailona microwave, i mea e hoʻokō ai i nā hana like ʻole, e like me ka ʻike obstacle, collision warning, adaptive cruise control, etc .
Kuʻuna hana
Hoʻohana like ka radar microwave automotive me ka radar maʻamau, ʻo ia hoʻi, hoʻouna ʻo ia i ka nalu uila (microwave) a laila loaʻa ka leo e like me ka ʻokoʻa manawa ma waena o ka loaʻa ʻana a me ka loaʻa ʻana, i mea e ana i ka ʻikepili kūlana o ka pahuhopu. ʻO ke ʻano kikoʻī, hoʻopuka nā radar microwave i nā hōʻailona microwave e hoʻihoʻi i ka wā e hālāwai ai lākou i nā pilikia, a ua helu ka radar i ka mamao ma ke ana ʻana i ka manawa holo kaʻapuni o nā hōʻailona. Eia kekahi, hiki i ka microwave radar ke ʻike i ka wikiwiki a me ke kuhikuhi o kahi mea ma ka nānā ʻana i nā hiʻohiʻona o ka hōʻailona hōʻike ʻia, e like me ka hopena Doppler .
Hoʻolālā noi
Loaʻa i ka automotive microwave radar nā hiʻohiʻona noiʻi i nā kaʻa:
collision warning : ma ka ʻike ʻana i nā pilikia ma mua, e ʻōlelo mua, e kōkua i ka mea hoʻokele e hana i nā mea e pale aku ai i ka hui ʻana.
adaptive cruise control : Hoʻoponopono ʻakomi i ka wikiwiki o ka holo moku e like me ka puni o ke kaʻa, e mālama ana i kahi mamao palekana mai ke kaʻa i mua .
pedestrian detection : Ma ka ʻōnaehana kaʻa kaʻa, hiki i ka microwave radar ke ʻike i ka poʻe hele wāwae a me nā mea pilikia ʻē aʻe e hōʻoia i ka palekana o ke kaʻa.
kaʻa kaʻa : E kōkua i ke kaʻa e ʻimi maʻalahi i kahi kaʻa kaʻa kūpono i ka hale kaʻa a hoʻopau i ka hana kaʻa .
Nā palena ʻenehana a me nā ʻano hana
Hoʻohana maʻamau nā radar microwave automotive i nā pūna nalu millimeter, e like me 24GHz, me nā alapine kiʻekiʻe a me nā lōʻihi hawewe pōkole. ʻO kēia ka mea i loaʻa i ka microwave radar ke kuhikuhi kiʻekiʻe a me ka hoʻonā ʻana, a hiki ke ʻike pololei i nā pahuhopu kokoke. Eia kekahi, ʻaʻole pili ka microwave radar e ka ʻike a hiki ke hana maʻamau i nā kūlana ʻino. Eia nō naʻe, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ka microwave radar, a ʻo ka hiki ke ʻike i nā mea liʻiliʻi ʻaʻole maikaʻi e like me ka lidar .
ʻO nā hana nui o ka automotive microwave radar e pili ana i kēia mau ʻano:
ʻO ka ʻōlelo aʻo ʻana o ka Collision and Automatic Emergency Braking (AEB) : ʻIke ʻia nā radar Microwave i nā pilikia ma mua a inā pono e hoʻomaka i kahi ʻōnaehana hoʻokele ulia pōpilikia e pale aku i kahi hui.
pedestrian detection : Ma o ka microwave radar, hiki i na kaa ke hoomaopopo a ike i ka poe hele wawae, pela e hoonui ai i ka palekana o ke kalaiwa .
Mākaʻikaʻi makapō a me ke ala ʻŌlelo haʻalele : hiki i ka microwave radar ke nānā i ka wahi makapō o kahi kaʻa e pale ai i ka hui ʻana me nā kaʻa ʻē aʻe i ka wā e hoʻololi ai i nā alahele, a hiki ke nānā i ka haʻalele ʻana o ke alahele a hoʻomaopopo i nā mea hoʻokele i .
Adaptive cruise control (ACC) : Hiki i ka Microwave radar ke kōkua i nā kaʻa e mālama i kahi mamao palekana mai ke kaʻa i mua o ka adaptive cruise control .
Rear Traffic Warning (RCTA) : hiki i ka microwave radar ke nānā i ke kaʻa ma hope o ke kaʻa, e hoʻomanaʻo i ka mea hoʻokele e hoʻolohe i ke kaʻa e hiki mai ana, e pale i ka hoʻohuli ʻana.
ʻO ka loina hana o ka microwave radar ʻo ia ke ana i ke kūlana o ka pahuhopu ma ka hoʻouna ʻana i nā nalu uila (nā nalu radar) a me ka loaʻa ʻana o ka leo e like me ka ʻokoʻa manawa ma waena o ka hoʻouna ʻana a me ka loaʻa. Aia ka alapine o ka radar nalu millimeter i ka pūna nalu millimeter, no laila ua kapa ʻia ʻo ia ka millimeter wave radar .
ʻO ka hoʻohana ʻana i nā ʻāpana alapine like ʻole o ka microwave radar i nā kaʻa e loaʻa i ʻelua mau pūʻulu o 24GHz a me 77GHz. Hoʻohana nui ʻia nā radar 24GHz no ka ʻike pōkole, ʻoiai ʻo 77GHz radar ka mea kiʻekiʻe aʻe a me ka liʻiliʻi liʻiliʻi, kūpono no ka ʻike lōʻihi .
?Inā makemake ʻoe e ʻike hou aku, e hoʻomau i ka heluhelu ʻana i nā ʻatikala ʻē aʻe ma kēia pūnaewele!
E ʻoluʻolu e kelepona iā mākou inā makemake ʻoe i ia mau huahana.
ʻO Zhuo Meng Shanghai Auto Co., Ltd. ua kūpaʻa e kūʻai aku i nā ʻāpana kaʻa MG&750 e kuai.
