Kana mota ine ma airbag maviri uye system ye pretensioner yebhandi rechigaro ikadonha, zvisinei nekumhanya, ma airbag ne seat belt pretensioner zvinoshanda panguva imwe chete, zvichikonzera kutambisa ma airbag panguva yetsaona inokurumidza, izvo zvinowedzera mari yekugadzirisa zvakanyanya.
Sisitimu yemabhagi maviri ine zviito zviviri, kana tsaona yaitika, inogona kusarudza yega kushandisa seat belt pretensioner kana seat belt pretensioner pamwe ne dual airbag panguva imwe chete zvichienderana nekumhanya uye kumhanya kwemotokari. Nenzira iyi, kana tsaona yaitika nekumhanya kwakaderera, sisitimu iyi inogona kungoshandisa seat belt kuchengetedza kuchengetedzeka kwemutyairi nemutakuri, pasina kutambisa ma air bags. Kana kumhanya kwacho kuri kupfuura 30km/h mutsaona, seat belt ne air bag zvinoshanda panguva imwe chete, kuitira kuchengetedza kuchengetedzeka kwemutyairi nemutakuri.
Musimboti wekushanda
Kana mota yaita tsaona, airbag control system inoona simba rekurova
(kudzikira kwesimba) kunodarika kukosha kwakatarwa, komputa yeairbag inobatanidza pakarepo circuit yemagetsi inoputika mu inflator, inobatidza nzvimbo yekupisa iri mu electric explosion tube, uye murazvo unobatidza ignition powder ne gas generator, zvichiburitsa gasi rakawanda pa 0. Mukati memasekonzi 03, air bag inofuridzwa, air bag inokura zvakanyanya, inopwanya nepakati pedhiramu rekushongedza riri pa steering wheel kuenda kumutyairi nemugari, zvekuti mutyairi nemugari nemusoro wemugari zvinodzvanywa pa air bag yakazara ne gasi, zvichidzivirira kukanganiswa kwemutyairi nemugari, uye zvino zvinoburitsa gasi riri mu air bag.
Begi remhepo rinogona kuparadzira simba rekurova mumusoro nepachipfuva zvakaenzana, richidzivirira muviri wemufambi asina kusimba kuti usarove zvakananga nemuviri, zvichideredza zvikuru mukana wekukuvara. Mabegi emhepo anodzivirira vafambi kana vakarovera pamberi, kunyangwe bhandi rechigaro risina kupfeka, mabegi emhepo anodzivirira kuputika achiri kushanda zvakakwana kuderedza kukuvara. Zvichienderana nehuwandu, kana mota ikarovera pamberi ine mabegi emhepo, huwandu hwekukuvara kwemufambi hunogona kuderedzwa kusvika ku64%, kunyangwe mu80% yevafambi ivavo havasi kupfeka mabhandi echigaro. Kurovera kubva padivi nezvigaro zvekumashure kuchiri kuenderana nebasa rebhandi rechigaro.
Pamusoro pezvo, huwandu hwekuputika kwebhegi remhepo hunongova madecibel zana nemakumi matatu chete, ayo ari mukati mehukuru hunogona kushivirira muviri wemunhu; 78% yegasi riri mubhegi remhepo initrogen, iyo inogara kwenguva refu uye haina chepfu, haina njodzi kumuviri wemunhu; Hupfu hunoburitswa kana kuputika hupfu hunozora hunoita kuti bhegi remhepo rirambe rakapetwa uye risinganamati pamwe chete, uye hahukuvadzi muviri wemunhu.
Zvese zvinhu zvine munondo unocheka nemativi maviri, uye airbag inewo divi rayo risina kuchengetedzeka. Zvichienderana nekuverenga, kana mota iri kufamba ne60km/h, kurovera kamwe kamwe kuchaita kuti mota imire mukati memasekonzi 0.2, uye airbag ichabuda nekumhanya kweinenge 300km/h, uye simba rekurova rinosvika 180 kg, izvo zvakaoma kutakura musoro, mutsipa nedzimwe nhengo dzemuviri wemunhu dzisina kusimba. Saka, kana Angle nesimba re airbag richibuda zvisina kunaka zvishoma, zvinogona kukonzera "njodzi".
Mumota, masensa matatu anogara achiisa ruzivo rwekuchinja kwekumhanya kune electronic controller, electronic controller inogara ichiverenga, ichiongorora, ichienzanisa uye ichiongorora, uye inenge yakagadzirira kupa mirairo chero nguva. Kana kumhanya kuri pasi pe30km/h, sensor yekumberi nesensa yayo yekuchengetedza yakabatana zvinoisa chiratidzo chekudonha kune electronic controller panguva imwe chete, uye zvinotumira murairo wekuputitsa detonator yemagetsi yepretensioner yebhandi rechigaro, nepo chiratidzo chinotumirwa necentral sensor chisingakwanise kuita kuti electronic controller itumire murairo wekuputitsa detonator yemagetsi yebhegi remhepo. Saka, kana paine kudonha kwekukurumidza (kuderera kwekukurumidza), chero bedzi pre-tensioner ichidhonza bhandi rechigaro kumashure, zvakakwana kudzivirira mutyairi nemutakuri kuti vasarove pamberi.
Kana paine kuroverana kwekukurumidza (kudzikamisa kukuru), sensor yekumberi nesensor yepakati zvinoisa chiratidzo chekuroverana panguva imwe chete kumutongi wemagetsi, mutongi wemagetsi anoburitsa murairo mushure mekuongorora nekukurumidza, uye anoputitsa ma detonator emagetsi ekudzivirira kuruboshwe nekurudyi uye ma air bags maviri panguva imwe chete. Kana bhandi rechigaro radhonzwa zvakasimba, ma air bags maviri anovhurika panguva imwe chete kuti atore simba remagetsi rinogadzirwa nemutyairi nemutakuri nekuda kwekudzikiswa kukuru kwekumhanya, zvichidzivirira kuchengetedzeka kwavo.
Kana mota ikaroverana nechinhu chakagadzika chiri pamberi payo, mota inomhanya zvikuru, ndipo painodzikira speed, uye simba rinotorwa nesensor. Kana simba rakagara ragadziriswa resensor yekumberi nesensor yepakati rakakamurwa kuita miganhu yepamusoro neyakaderera, kureva kuti, kumhanya kweimpact kwesensor yekumberi kuri pasi pemutengo wepasi we30km/h, uye kukosha kwakarongeka kwesensor yekuchengetedza kuriwo mutengo wepasi, saka electronic controller inongoita kuti seat belt pretensioner iputike kana mota yadonha nekumhanya kwakaderera. Kana kukosha kwakatarwa kwesensor yekumberi kuri muganho wepamusoro, kana mota yadonha nekumhanya kwakakwirira, front sensor, central sensor nesensor yekuchengetedza panguva imwe chete zvinoburitsa chiratidzo chekudonha kune electronic controller, uye electronic controller inoputika ma detonator ese emagetsi, bhandi rechigaro rinomanikidzwa uye bhegi remhepo rinovhurwa.
Kubva pakuroverana, sensor inotumira chiratidzo kune controller iyo inosarudza kuputira detonator yemagetsi, nguva inosvika 10ms. Mushure mekuputirana, jenareta yegesi inogadzira huwandu hwakawanda hwenitrogen, iyo inokurumidza kuputira bhegi remhepo. Kubva pakuroverana kusvika pakuumbwa kwebhegi remhepo, uye kusvika pakusimba kwebhandi rechigaro, maitiro ese anotora 30-35ms, saka kudzivirira kwehurongwa hwebhegi remhepo kwakanaka kwazvo.
Kana bhegi remhepo richiputika, nekuda kwehuwandu hwakawanda hwegasi rinogadzirwa mubhegi remhepo, kumanikidzwa kwebhegi remhepo kunowedzera, izvo zvisingakodzeri kupinza simba remhepo, saka kune maburi maviri ekuburitsa gasi kumashure kwebhegi remhepo kuti ribudise kumanikidzwa, izvo zvinobatsira kuchengetedza kuchengetedzeka kwemutyairi nemutakuri.
Senzira yekubatsira kuchengetedza muviri, vanhu vanowedzera kuiteerera. Kana mota nezvipingamupinyi zvikaroverana, inonzi kuroverana, munhu ari mumotokari nezvinhu zvemota zvinoroverana, inonzi kuroverana kwechipiri, bhegi remhepo richiroverana, kuroverana kwechipiri kusati kwavhurwa nekukurumidza kwemuchina wemhepo wakazadzwa negasi, kuitira kuti munhu ari mumotokari nekuda kwekusagadzikana uye kufamba "pamuchina wemhepo" kuderedza kuroverana kwemunhu ari mumotokari uye kutora simba remumotokari, kuderedza kukuvara kwemunhu ari mumotokari.
Mabhegi emhepo akagadzirwa nekukurumidza mumakore achangopfuura, mutengo wadzikira zvakanyanya, uye mota ine mabhegi emhepo yavewo ichikura kubva kumotokari dzepakati nedzevakuru dzekare kusvika kumotokari dzepakati nedzepasi. Panguva imwe chete, dzimwe mota dzine mabhegi emhepo evafambi ari pamberi (ndiko kuti, magadzirirwo emabhegi maviri emhepo), uye mabhegi emhepo evafambi akafanana neaya anoshandiswa nevatyairi, asi huwandu hwebhegi remhepo hwakakura uye gasi rinodiwa rakatowanda. Kubva kuma1990, mashandiro ekuchengetedza ebhegi remhepo akagamuchirwa kazhinji, uye anoonekwa sechishandiso chekuchengetedza chemazuva ano uye chepamusoro. Kunzwisisa musimboti wekushanda kwebhegi remhepo nezvinhu zvinoda kutariswa zvakakosha kuti tizvidzivirire zviri nani, asi kumutyairi, kutyaira zvakachengeteka ndiko kwekutanga, uko kusina mudziyo wekuchengetedza wepamusoro unogona kutsiviwa.
