Izinhlelo zebhuleki eziphuthumayo

Enye yamathuluzi ayisihluthulelo avimbela izingozi noma anciphise imiphumela yawo uhlelo lwamabhuleki oluphuthumayo. Kuyadingeka ukusebenza ngempumelelo kohlelo lwamabhuleki esimweni esibucayi: ngokwesilinganiso, ibhuleki lemoto lehliswa ngamaphesenti angamashumi amabili. Ngempela i-BAS noma i-Brake Assistant ingahunyushwa ngokuthi “umsizi wamabhuleki”. Uhlelo lokusiza amabhuleki oluphuthumayo (kuya ngohlobo) lungasiza umshayeli kubhuleki ophuthumayo (“ngokucindezela” ibhuleki), noma libhuleke imoto ngokuzenzakalela ngaphandle kokubamba komshayeli ize ime ngokuphelele. Esihlokweni, sizocubungula idivaysi, inqubo yokusebenza nezinhlobo zalezi zinhlelo zombili.

Izinhlobo zezinhlelo zokubopha eziphuthumayo ezisizayo

Kunamaqembu amabili amasistimu okusiza amabhuleki aphuthumayo:

• usizo lwamabhuleki oluphuthumayo;
• othomathikhi braking eziphuthumayo.

Eyokuqala idala ingcindezi enkulu yokubamba amabhuleki ngenxa yomshayeli ocindezela ibedali yebhuleki. Eqinisweni, "ibhuleki" kumshayeli. Owesibili wenza umsebenzi ofanayo, kepha ngaphandle kokubamba iqhaza komshayeli. Le nqubo iyazenzakalela.

Uhlelo lokusiza amabhuleki oluphuthumayo

Ngokuya ngomgomo wokudala ingcindezi enkulu yokubopha amabhuleki, lolu hlobo lohlelo luhlukaniswe lwangumoya kanye ne-hydraulic.

I-Pneumatic Emergency Brake Assist

Uhlelo lwe-pneumatic luqinisekisa ukusebenza kahle okuphezulu kwe-vacuum brake booster. Iqukethe izinto ezilandelayo:

1. inzwa etholakala ngaphakathi kwe-vacuum amplifier nokulinganisa ijubane lokuhamba kwenduku yokukhulisa;
2. i-electromagnetic rod drive;
3. iyunithi yokulawulwa kwe-elekthronikhi (ECU).

Uhlobo lwe-pneumatic lufakwe ikakhulu ezimotweni ezifakwe i-anti-lock braking system (ABS).

Umgomo wesistimu ususelwa ekwamukelweni kohlobo lwamabhuleki aphuthumayo ngejubane lapho umshayeli ecindezela khona iphedali yamabhuleki. Lesi sivinini siqoshwa inzwa, ehambisa umphumela ohlelweni lokulawula ngogesi. Uma isiginali inkulu kunenani elibekiwe, i-ECU isebenzisa i-rod actuator solenoid. I-vacuum brake booster icindezela i-pedal pedal esitobhini. Ngisho nangaphambi kokuba kuqale i-ABS, kwenzeka ukubopha amabhuleki okuphuthumayo.

Izinhlelo zokusiza amabhuleki eziphuthumayo zomoya zifaka:

• I-BA (I-Brake Assist);
• I-BAS (Uhlelo lwe-Brake Assist);
• I-EBA (Emergency Brake Assist) - efakwe ezimotweni zakwaVolvo, Toyota, Mercedes, BMW;
• I-AFU - yeCitroen, Renault, Peugeot.

Umfutholuketshezi Emergency Brake Assist

Uhlobo lwe-hydraulic lohlelo lwe "break assist" lwakha ingcindezi ephezulu kakhulu yohlelo lwamabhuleki ngenxa yezakhi ze-ESC (Vehicle Stability Control).

Ngokwesakhiwo, uhlelo luqukethe:

1. ukubopha ingcindezi inzwa;
2. inzwa yesivinini samasondo noma inzwa yokuphumula ku-amplifier yokukhulisa umoya;
3. ibhuleki switch;
4. ECU.

Uhlelo lunezinhlobo eziningana:

• I-HBA (Hydraulic Braking Assistance) ifakwe kwiVolkswagen, Audi;
• IHBB (Hydraulic Brake Booster) nayo ifakiwe kwa-Audi nakuVolkswagen;
• I-SBC (Sensotronic Brake Control) - eyenzelwe iMercedes;
• I-DBC (Dynamic Brake Control) - efake iBMW;
• I-BA Plus (Brake Assist Plus) - iMercedes.

Ngokuya ngamasignali avela ezinzwa, i-ECU ivula ipompo ye-hydraulic yohlelo lwe-ESC futhi inyuse ingcindezi ohlelweni lwamabhuleki iye enanini eliphakeme.

Ngaphezu kwejubane lapho kusetshenziswa khona iphedali yamabhuleki, i-SBC ibheka ingcindezi esephedini, ebusweni bomgwaqo, lapho kuhamba khona uhambo, nezinye izinto. Ngokuya ngezimo ezithile, i-ECU ikhiqiza amandla afanele amabhuleki esondo ngalinye.

Ukuhlukahluka kwe-BA Plus kucabangela ibanga lemoto engaphambili. Uma kunengozi, uxwayisa umshayeli, noma amabhuleki kuye.

Okuzenzakalelayo braking uhlelo oluphuthumayo

Uhlelo lwe-braking oluphuthumayo lwalolu hlobo seluthuthuke kakhulu. Ithola imoto ngaphambili noma isithiyo isebenzisa i-radar nekhamera yevidiyo. Isakhiwo ngokuzimela sibala ibanga lemoto futhi uma kwenzeka kwenzeka ingozi yehlisa ijubane. Ngisho nokushayisana okungenzeka, imiphumela ngeke ibe mibi kangako.

Ngaphezu kwe-braking ephuthumayo ezenzakalelayo, idivayisi ifakwe neminye imisebenzi. Okufana nalokhu: ukuxwayisa umshayeli ngengozi yokushayisana ngokusayina komsindo nokukhanya. Futhi, amanye amadivayisi okuphepha angenziwanga ayasebenza, ngenxa yokuthi okuyinkimbinkimbi kunegama elehlukile - "uhlelo lokuphepha lokuvikela".

Ngokwesakhiwo, lolu hlobo lohlelo lokubhaka amabhuleki oluphuthumayo lususelwa kwezinye izinhlelo zokuphepha ezisebenzayo:

• i-adaptive cruise control (ukulawula ibanga);
• izinga lokushintshaniswa kwesilinganiso sokushintshaniswa (ukubopha okuzenzakalelayo)

Izinhlobo ezilandelayo zezinhlelo zokubopha amabhuleki eziphuthumayo ziyaziwa:

• I-Pre-Safe Brake - yeMercedes;
• I-Collision Mitigation Braking System, ama-CMBS ayasebenza emotweni yakwaHonda;
• Idolobha Brake Control - Cityиат;
• I-Active City Stop and Forward Alert - efakwe kuFord;
• Phambili Ukunciphisa Ukungqubuzana, i-FCM- Mitsubishi;
• I-City Emergency Brake - Volkswagen;
• Ukuphepha Kwedolobha kusebenza kuVolvo.
