Izingxenye eziyinhloko zesistimu yokulawula imoto uhlelo lokulawula, umzimba kanye ne-chassis, ukunikezwa kwamandla emoto, uhlelo lokuphatha ibhethri, i-drive motor, uhlelo lokuvikela ukuphepha. Ukukhishwa kwamandla, ukuphathwa kwamandla, kanye nokutholwa kwamandla kwezimoto zikawoyela zendabuko kanye nezimoto zamandla amashazihlukile. .Lokhu kuqedwa uhlelo lokulawula imoto ngogesi.
Isilawuli semoto siyisikhungo sokulawula ukushayela okuvamile kwezimoto zikagesi, ingxenye eyinhloko yesistimu yokulawula imoto, kanye nezingxenye eziyinhloko zokulawula ukushayela okuvamile kwezimoto ezisebenza ngogesi, ukuvuselela amandla okubhuleka okuvuselelayo, ukuhlonzwa kwephutha nokucubungula, nokuqapha isimo semoto. Ngakho-ke iyini imisebenzi yohlelo olusha lokulawula imoto yamandla?Ake sibheke okulandelayo.
1. Umsebenzi wokushayela imoto
Injini yamandla yemoto entsha yamandla kufanele ikhiphe itorque yokushayela noma yokubhuleka ngokuvumelana nenhloso yomshayeli.Lapho umshayeli enyathela i-accelerator pedal noma i-brake pedal, injini yamandla kufanele ikhiphe amandla athile okushayela noma amandla okubhuleka avuselelayo.Uma kukhulu ukuvuleka kwe-pedal, amandla okukhiphayo emoto yamandla amakhulu.Ngakho-ke, umlawuli wemoto kufanele achaze ngokunengqondo ukusebenza komshayeli; thola ulwazi lwempendulo evela ezinhlelweni ezingaphansi zemoto ukuze unikeze impendulo yokuthatha izinqumo kumshayeli; futhi uthumele imiyalo yokulawula ezinhlelweni ezingaphansi zemoto ukuze uzuze ukushayela okuvamile kwemoto.
2. Ukuphathwa kwenethiwekhi yemoto
Ezimotweni zesimanje, kunamayunithi amaningi okulawula ama-elekthronikhi namathuluzi okulinganisa, futhi kukhona ukushintshana kwedatha phakathi kwawo. Ukwenza kanjani lokhu kushintshana kwedatha kusheshe, kuphumelele, futhi kudlulise okungenazinkinga kuba yinkinga. Ukuze kuxazululwe le nkinga, inkampani yaseJalimane ye-BOSCH ku-20 I-Controller Area Network (CAN) yasungulwa ngawo-1980.Ezimotweni ezisebenza ngogesi, amayunithi okulawula ama-elekthronikhi ayinkimbinkimbi kakhulu kunezimoto ezijwayelekile zikaphethiloli, ngakho-ke ukusetshenziswa kwebhasi le-CAN kubalulekile.Isilawuli semoto singesinye sezilawuli eziningi zezimoto zikagesi kanye ne-node ebhasini le-CAN.Ekulawulweni kwenethiwekhi yezimoto, isilawuli semoto siyisikhungo sokulawula ulwazi, sinesibopho sokuhlela nokudlulisa ulwazi, ukuqapha isimo senethiwekhi, ukuphathwa kwezindawo zenethiwekhi, nokuxilongwa kwephutha lenethiwekhi nokucubungula.
3. Ukulawula impendulo ye-Braking energy
Izimoto ezintsha zamandla zisebenzisa amamotho kagesi njengendlela yokuphuma yokushayela i-torque.I-motor kagesi inokusebenza kwe-regenerative braking. Ngalesi sikhathi, i-motor kagesi isebenza njengejeneretha futhi isebenzisa amandla okubhuleka emoto kagesi ukukhiqiza ugesi. Ngesikhathi esifanayo, la mandla agcinwa endaweni yokugcina amandlaidivayisi. Lapho ukushajaizimo ziyahlangatshezwa, amandla ashajwa ngokuhlanekezela ebhethrini lamandlaiphakethe.Kule nqubo, isilawuli semoto siyahlulela ukuthi impendulo yamandla okubhuleka ingenziwa yini ngesikhathi esithile ngokuya ngokuvulwa kwe-accelerator pedal kanye ne-brake pedal kanye nenani le-SOC lebhethri lamandla. Idivayisi ithumela umyalo wokubhuleka ukuze ithole ingxenye yamandla.
4. Ukuphathwa kwamandla emoto kanye nokwenza kahle
Emotweni kagesi ehlanzekile, ibhethri alinikezi nje amandla enjini yamandla, kodwa futhi linikeza amandla ezinsizakalweni zikagesi. Ngakho-ke, ukuze kutholwe ibanga lokushayela eliphakeme kakhulu, isilawuli semoto sizoba nesibopho sokuphatha amandla emoto ukuze kuthuthukiswe izinga lokusebenzisa amandla.Uma inani le-SOC lebhethri liphansi uma kuqhathaniswa, isilawuli semoto sizothumela imiyalo kwezinye izesekeli zikagesi ukuze kukhawulwe amandla okukhipha ezisekeli zikagesi ukuze kwandiswe ibanga lokushayela.
5. Ukuqapha nokuvezwa kwesimo semoto
Isilawuli semoto kufanele sithole isimo semoto ngesikhathi sangempela, futhi sithumele ulwazi lwesistimu engaphansi ngayinye kusistimu yokubonisa ulwazi lwemoto. Inqubo iwukubona isimo semoto kanye nezinhlelo zayo ezingaphansi ngezinzwa nebhasi le-CAN, bese ushayela ithuluzi lokubonisa. , ukukhombisa imininingwane yesimo kanye nolwazi lokuxilongwa kwamaphutha ngethuluzi lokubonisa.Okuqukethwe kwesibonisi kufaka phakathi: isivinini semoto, isivinini semoto, amandla ebhethri, imininingwane yephutha, njll.
6. Ukuxilongwa kwephutha nokwelashwa
Ngokuqhubekayo uqaphe uhlelo lokulawula imoto nge-elekthronikhi ukuze uthole ukuxilongwa kwephutha.Isikhombi sephutha sibonisa isigaba samaphutha namanye amakhodi amaphutha.Ngokusho kokuqukethwe okuyiphutha, yenza inqubo yokuvikela ukuphepha ngesikhathi esifanele.Ngamaphutha angathí sina kakhulu, kuyenzeka ukushayela ngesivinini esiphansi uye esiteshini sokulungisa esiseduze ukuze silungiswe.
7. Ukuphathwa kokushaja kwangaphandle
Bona ukuxhunywa kokushaja, qapha inqubo yokushaja, bika isimo sokushaja, bese umisa ukushaja.
8. Ukuxilongwa ku-inthanethi nokutholwa ungaxhunyiwe ku-inthanethi kwemishini yokuxilonga
Inesibopho sokuxhumanisa nokuxhumana kokuxilonga ngemishini yokuxilonga yangaphandle, futhi ibona izinsizakalo zokuxilonga ze-UDS, okuhlanganisa ukufundwa kokusakaza idatha, ukufundwa kwekhodi yephutha nokusula, kanye nokulungisa iphutha lamachweba okulawula.
