Ifanele Volvo iloli uwoyela umfutho inzwa 20796744

Ngokuthuthuka kobuchwepheshe be-elekthronikhi bedekhoda yezimoto, izinga lobunjiniyela lokuphazanyiswa kwe-automobile electronic liye lathuthukiswa ngokuqhubekayo. Uhlelo olujwayelekile lwemishini kube nzima ukuxazulula ezinye zezinkinga zokukhipha amakhodi ezihlobene nezidingo zokusebenza kwemoto, futhi luthathelwe indawo uhlelo lokulawula ngogesi. Umsebenzi wenzwa uwukunikeza ngobuningi amasignali awusizo okukhipha ugesi ngokuya ngosayizi okaliwe oshiwo, okungukuthi, inzwa iguqula amanani angokwenyama namakhemikhali afana nokukhanya, isikhathi, ugesi, izinga lokushisa, ingcindezi negesi kube amasignali. Njengengxenye eyinhloko yesistimu yokulawula i-elekthronikhi yezimoto, inzwa ithinta ngokuqondile ukusebenza kobuchwepheshe bemoto. Kunezinzwa ezingaba ngu-10-20 ezimotweni ezijwayelekile, nokunye okuningi ezimotweni zikanokusho. Lezi zinzwa zisatshalaliswa kakhulu ohlelweni lokulawula injini, uhlelo lokulawula i-chassis kanye nohlelo lokulawula umzimba.

Inzwa yokulawula i-chassis

Izinzwa zokulawula i-chassis zibhekisela kuzinzwa ezisatshalaliswa kusistimu yokulawula ukudluliswa, isistimu yokulawula ukumiswa, isistimu yokuqondisa amandla kanye ne-anti-lock braking system. Zinemisebenzi ehlukene kumasistimu ahlukene, kodwa izimiso zazo zokusebenza ziyefana nalezo ezisezinjinini. Ngokuyinhloko kunezinhlobo ezilandelayo zezinzwa:

1. Inzwa yokulawula ukudlulisa: isetshenziswa kakhulu ukulawula ukudluliswa okuzenzakalelayo okulawulwa ngogesi. Ngokolwazi olutholwe ekutholweni kwenzwa yesivinini, inzwa yokusheshisa, inzwa yomthwalo wenjini, inzwa yesivinini senjini, inzwa yokushisa kwamanzi kanye nenzwa yokushisa kawoyela, yenza idivayisi yokulawula i-elekthronikhi ilawule indawo yokushintsha futhi ikhiye isiguquli se-torque esebenza ngogesi, ukuze ukuze kuzuzwe amandla esiphezulu kanye esiphezulu fuel ukonga.

2. Izinzwa zokulawula isistimu yokumiswa: ikakhulukazi zihlanganisa inzwa yesivinini, inzwa yokuvula i-throttle, inzwa yokusheshisa, inzwa yobude bomzimba, inzwa ye-engeli yesiteringi, njll. Ngokolwazi olutholiwe, ubude bemoto bulungiswa ngokuzenzakalelayo, kanye nokushintsha kwemoto. ukuma kuyacindezelwa, ukuze kulawulwe ukunethezeka, ukusingatha ukuzinza kanye nokuzinza kokushayela kwemoto.

3. Inzwa yesistimu yokuqondisa amandla: Yenza uhlelo lokulawula amandla kagesi lubone ukusebenza kokuqondisa okukhanyayo, luthuthukise izici zokuphendula, ukunciphisa ukulahlekelwa injini, ukwandisa amandla okukhipha kanye nokulondoloza uphethiloli ngokusho kwenzwa yesivinini, inzwa yesivinini senjini kanye nenzwa ye-torque.

4. Inzwa yokubhuleka i-anti-lock: Ibona isivinini sesondo ngokwenzwa ye-angular velocity yesondo, futhi ilawula umfutho kawoyela wokubhuleka ukuze ithuthukise ukusebenza kwebhuleki lapho izinga lokushibilika kwesondo ngalinye liku-20%, ukuze kuqinisekiswe ukuhamba kahle nokuhamba. ukuzinza kwemoto.
