Ko te mahi matua o te waeine whakahaere tīmatanga waka
Hei "pokapū io" o te pūnaha hiko, he hononga nui te waeine whakahaere tīmatanga waka e hono ana i ngā tohutohu a te taraiwa ki te mahi a te miihini. Ko ōna mahi e kapi ana i te whakahaere hiko, te tiaki haumaru, me te whakahaere atamai puta noa i ngā āhuatanga maha.
Mai i te tirohanga o te putanga hiko, ka whakauruhia e te waeine whakahaere miihini (ECU) ngā raraunga mai i ngā wāhanga pēnei i ngā pūoko tūranga o te toki porowhita me ngā pūoko rere hau hei whakarite tika i te whānui o te pā o te werohanga wahie me te koki whakamua mura me te tere urupare taumata-mirihēkona. I roto i ngā āhuatanga whakaterenga ohorere, ka whakanuia e te ECU te rahinga werohanga wahie me te whakatere i te wā mura i te wā kotahi, ka whakarei ake i te urupare mana mā te 15%-25%; i roto i ngā āhuatanga noho kore, ka pupuri i te ōwehenga hau-wahie tino pai o te 14.7:1 mā te whakahaere porowhita kati, ka whakarite i te mahi miihini pumau me te whakanui ake i te penapena wahie mā te 8%-12%. Ko te waeine whakahaere mura (ICM), hei pana hiko mana, ka whakahaere tika i te ara iahiko tuatahi o te koiri mura i runga i ngā tohutohu a te ECU, ka whakaputa hiko ngaohiko teitei hei whakarato hiko ki te mono mura, hei kaiwhakahaere tika mō te mura o te miihini.
Ko te mahi tiaki haumaru tētahi atu uara matua o te waeine whakahaere tīmatanga. Ina kitea ngā rahunga o te pūoko, te pahūtanga, me ētahi atu hapa rānei, ka rongoa tonu te ECU i te waehere hapa ka whakaoho i te rama whakatūpato o te papaaho. I ngā wā tino kino, ka whakahohehia e ia te aratau ngoikore hei whakawhāiti i te putanga hiko, hei ārai i ngā kino atu ki te miihini. Ka whakamahia e te waeine whakahaere tinana (BCM) te whatunga CAN hei whakatutuki i te tiakitanga taurite o te arorau tīmatanga. Ina tae te tere o te waka ki te 10 km/h, ka raka aunoa i ngā tatau, ka whakaoho i ngā whakaoho oro me ngā whakaoho tirohanga mēnā ka uru turekore, ā, ka ārai i te tīmatanga turekore mā te pūnaha ārai tahae miihini. Hei tāpiri, he āheinga whakahaere hiko kei te waeine whakahaere tīmatanga, e whakauru ana i te tuku hiko o ngā taputapu hiko tuku iho, e whakaiti ana i te maha o ngā taura waea neke atu i te 40%, e whakaiti ana i te mōrearea o ngā ara iahiko poto me te kakahu, me te whakapai ake i te pai o te tiaki.
Ngā āhuatanga hapa noa o te kōwae whakahaere tīmatanga
I te koroheketanga o te waka, ka pāngia pea te waeine whakahaere tīmatanga e ngā raruraru maha nā te koroheketanga o ngā wāhanga, ngā hapa waea rānei, e toru ngā momo e kitea ana: te tīmatanga rerekē, te piki me te heke o te mana, me te whakapaunga pūngao rerekē.
Ko te āhuatanga tino kitea ko te rahunga o te tīmatanga. Ina rahunga te waeine whakakā, ka kore e taea te whakahaere tika i te wā whakakā, ka uaua ai te tīmatanga o te miihini, ka kore rānei e taea te whakakā. Mēnā he rahunga hiko, he kino rānei te mahara o te ECU, ka arahi tika atu ki te rahunga o ngā tohutohu whakakā me te werohanga wahie, ka tino pararutiki te pūnaha tīmatanga. Tērā pea ka pāngia ētahi tauira e ngā āhuatanga rerekē o te tīmatanga nā te rahunga o te whakawhitiwhiti kōrero CAN, pērā i te waehere hapa P00A8 e tohu ana i te motuhanga o te tuku tohu i waenga i ngā waeine waka, ka kore ai e taea e te whakawhiti tīmatanga te whiwhi i ngā tohutohu a te ECU.
Ko ngā rerekētanga o te putanga hiko te whakaaturanga huna o te hapa. Ka puta he tahunga koretake i te waeine mura e te hapa, ka hua ake he koretake o te hiko i te wā e whakahaerehia ana te waka, ka puhoi te whakaterenga, ka roa te pikinga tere mō te 0.5-1 hēkona pea; i ngā āhuatanga mangere, ka pāngia hoki te mīhini e ngā wiri ā-wā, ā, i ngā wā kino, ka kati tika. Ka taea hoki e ngā raraunga pūoko ECU rerekē te whakararu i te hiko, hei tauira, ko te rerekētanga o te tohu pūoko rere hau ka arahi ki te tataunga werohanga wahie hē, ka puta ai te motumotu hiko i te wā e huri ana te kawenga.
Ko te whakamahinga pūngao me ngā tukunga koretake he pānga o te hapa. Mēnā he hapa te mōkihi mura, ka kore e tino tahuna te ahi, ka piki ake te whakamahinga wahie mā te 10%-15%, ā, ka nui ake ngā tukunga hauota waro me te hauota waro i te paerewa mā te 2-3 ngā wā. Mēnā ka uru te ECU ki te aratau ngoikore, ka mau tonu te mahi taketake mā te whakawhāiti i te nui o te weronga wahie, ahakoa ka taea te ārai i te kino o te miihini, ka nui ake te pikinga o te whakamahinga wahie, ā, i ētahi tauira, ka piki ake pea te whakamahinga wahie.
Te tautuhi hapa me ngā rautaki urupare
Ina pāngia ngā hapa o te kōwae whakahaere tīmatanga, me whakamahi i tētahi tikanga rapurongoā maha-ahu e whakakotahi ana i te tātari waehere hapa, te kimi tohu, me te whakamātautau wāhanga. I roto i te tātaritanga ngaio, ka whakatauhia tuatahitia te ahunga o te raruraru mā te pānui i ngā waehere hapa mā te OBD-II. Ka tohu tika ngā waehere P0351-P0358 ki te hapa o te kōwae mura, ko te P00A8 ia e tohu ana i te whakawhitiwhiti CAN rerekē. Kātahi ka kitea te ngaru hiko tuatahi o te kōwae mura mā te whakamahi i tētahi oscilloscope. Mena ka whakaatu te ngaru i te haruru, i te aukati rānei, ka taea te whakaū kua pakaru ngā wāhanga o roto o te kōwae. Mō ngā hapa ECU, me tirotiro anō mēnā kei roto te ngaohiko o te ara iahiko hiko i te awhe noa o te 13.5-14.5V, ā, i te wā kotahi, tātarihia mēnā he peka ke i roto i ngā tohu pūoko mā te tātari rere raraunga.
I roto i ngā mahi tiaki o ia rā, ka taea e ngā kaipupuri waka te aro wawe ki ngā whakatūpato mā te tirotiro i ngā āhuatanga rerekē. Mēnā ka pāngia te waka e te whakaroa tīmatanga neke atu i te 3 hēkona, te kaha wiri mangere neke atu i te 50 rpm ia meneti, te pikinga ohorere rānei o te whakapaunga wahie neke atu i te 10%, me haere tonu ki tētahi whare ngaio mō te whakamātautau. I te wā whakatikatika, me mōhio ko te whakakapi i te waeine mura me pania he hinu silicone kawe pāmahana teitei hei whakarite i te marara o te wera, ā, me whakamahi te kaupapa ECU i te kaupapa taketake i taurite ki te wheketere hei karo i ngā hapa tuarua i puta mai i te kore taurite o ngā tawhā. Hei tāpiri, ko te horoi auau i ngā putunga waro pūoko me te tirotiro i te pakari o te hononga taura waea ka taea te whakaiti i te tere o te puta o ngā hapa i roto i te waeine whakahaere tīmatanga. E whakarāpopoto ana te tuhinga i runga ake nei i ngā mahi matua, ngā hapa noa me ngā mahere urupare o te waeine whakahaere tīmatanga o te waka, e kapi ana i ngā tawhā hangarau me ngā whakaaro tiaki mahi. Ka taea te whakarato tohutoro mō ngā kaimahi tiaki waka, ā, ka āwhina hoki i ngā kaipupuri waka ki te mārama ki te arorau whakahaere o te pūnaha tīmatanga o te waka.
