ECU chii ichocho? Electronic control unit yeinjini yemotokari

ECU inhengo yemagetsi inodzora injini yemotokari, rimwe zita rayo mutungamiriri. Iyo inogamuchira ruzivo kubva kune akawanda ma sensors, inoagadzirisa zvinoenderana neakakosha algorithms uye, zvichibva pane yakagamuchirwa data, inopa mirairo kune iyo activator yehurongwa.

Iyo yemagetsi control unit chikamu chakakosha chemotokari pa-board network, inogara ichitsinhana data nezvimwe zvikamu zvehurongwa: anti-lock braking system, otomatiki kutapurirana, kudzikamisa mota uye kuchengetedza masisitimu, rwendo rwekufamba, kutonga kwemamiriro ekunze.

Kutsinhana kwemashoko kunoitwa kuburikidza neCAN bhazi, iyo inosanganisa ese emagetsi uye edhijitari masisitimu emotokari yemazuva ano mune imwe network.

Nekuda kweiyi nzira, zvinokwanisika kukwirisa kushanda kweinjini: kushandiswa kwemafuta, kupihwa kwemhepo, simba, torque, nezvimwe.

Mabasa makuru eECU ndeaya:

• manejimendi uye kutonga kwejekiseni remafuta mumajini ejekiseni;
• ignition control;
• kudzora nguva yevhavha;
• kudzora uye kuchengetedza tembiricha mujini inotonhorera system;
• throttle position control;
• kuongororwa kwekuumbwa kwemagesi emhepo;
• kutarisa kushanda kweiyo exhaust gasi recirculation system.

Uye zvakare, mutongi anogamuchira ruzivo nezve chinzvimbo uye kumhanya kwe crankshaft, kumhanya kwazvino kwemotokari, uye voltage mumotokari pa-bhodhi network. Zvakare, iyo ECU inoshongedzerwa neiyo diagnostic system uye, kana ichinge yaonekwa chero kusashanda kana kutadza, inozivisa muridzi nezvavo vachishandisa Check-Injini bhatani.

Chikanganiso chega chega chine kodhi yayo uye makodhi aya anochengetwa mumudziyo wekurangarira.

Paunenge uchiita diagnostics, nyanzvi dzinobatanidza mudziyo wekuongorora kune controller kuburikidza nekubatanidza, pane iyo skrini iyo makodhi ese ekukanganisa anoratidzwa, pamwe neruzivo nezve mamiriro einjini.

Electronic injini control unit.

Mutongi ibhodhi remagetsi rine microprocessor uye chiyeuchidzo chakavharwa mupurasitiki kana simbi. Panyaya yacho pane zvinongedzo zvekubatanidza kune mota pa-board network uye mudziyo wekuongorora. Iyo ECU inowanzoiswa mukati mejini compartment kana kumberi dashboard parutivi rwevafambi, kuseri kwegirovhosi. Mirayiridzo inofanira kuratidza nzvimbo yemutongi.

Kune yakajairika kushanda, akati wandei marudzi endangariro anoshandiswa mune yekudzora unit:

• PROM - programmable kuverenga-chete ndangariro - ine huru zvirongwa uye parameters injini;
• RAM - isina kurongeka yekuwana ndangariro, inoshandiswa kugadzirisa iyo yese dhata data, chengetedza yepakati mhedzisiro;
• EEPROM - chishandiso chemagetsi chinogadzirika chiyeuchidzo - chinoshandiswa kuchengetedza ruzivo rwakasiyana rwenguva pfupi: makodhi ekuwana uye makiyi, uye zvakare inoverenga ruzivo nezve mileage, injini yekushandisa nguva, kushandiswa kwemafuta.

Iyo ECU software ine maviri module: inoshanda uye kutonga. Yekutanga ine basa rekugamuchira data nekuigadzirisa, inotumira pulses kumidziyo yekuuraya. Iyo control module ine basa rekurongeka kwemasaini anouya kubva kune sensors uye, kana yekuona kusawirirana kupi neakatsanangurwa paramita, inotora zviito zvekugadzirisa kana kuvhara zvachose injini.

Shanduko kuECU software inogona kungoitwa kunzvimbo dzakatenderwa masevhisi.

Iko kudikanwa kwekugadzirisazve kunogona kusimuka kana chip tuning injini kuwedzera simba rayo uye kugadzirisa hunyanzvi hunhu. Kuvhiya uku kunogona kuitwa chete nesoftware yakasimbiswa. Zvisinei, vagadziri vemotokari vanozeza zvikuru kugovera ruzivo urwu, nokuti hazvisi mukufarira kwavo kuti vashandisi vachinje zvirongwa ivo pachavo.

ECU kugadzirisa uye kutsiva.

Kana mutongi akakundikana kana kuti asingashande zvakanaka, saka kutanga kune zvose zvinoratidzwa mukukundikana mukushanda kwejini, uye dzimwe nguva mukuvharwa kwayo kwakakwana. Check Engine inogona kugara ichiratidza kukanganisa kusingabviswe. Zvikonzero zvikuru zvekutadza kweECU ndezvi:

• kuwandisa, kupfupika kwedunhu;
• pesvedzero yezvinhu zvekunze - mwando, ngura, kuvhunduka, kutenheka.

Mukuwedzera, chero microprocessor inopisa kana iyo inotonhorera system ikatadza.

Kugadzirisa, pamwe nekutsiviwa kwechikwata chekutonga hazvizove zvakachipa. Sarudzo yakanakisa ndeyekutenga yuniti nyowani. Kuti uitore, iwe unofanirwa kuziva ese maparameter emuchina. Zvakakoshawo kuita zvigadziriso zvakanaka. Iyo komputa ichashanda zvakajairika chero inogamuchira masaini kubva kune ese ma sensors uye inochengetedza yakajairika voltage level munetiweki.
