Brake Assist - ke eng ka koloing 'me ke ea eng?

Ho netefatsa polokeho e kholo bakeng sa bakhanni, bapalami le ba tsamaeang ka maoto, bahlahisi ba likoloi ba kenya litsamaiso tse fapaneng tsa lithuso lihlahisoa tsa bona tse nolofatsang ts'ebetso ea ho khanna haholo.

E 'ngoe ea litsamaiso tsena ke brake assistant kapa Brake Assist System. Tlhalosong ea tlhophiso ea mohlala o itseng, o bitsoa BAS kapa BA. E qalile ho kenngoa ho tloha bohareng ba bo-1990 likoloing tsa Mercedes. Hamorao morero ona o ile oa nkoa ke Volvo le BMW.

BAS e fumaneha mefuteng e meng e mengata ea likoloi, ka mabitso a fapaneng feela:

• EBA (Emergency Brake Assist) - ka likoloi tsa Majapane, haholo-holo Toyota;
• AFU - likoloi tsa Fora Citroen, Peugeot, Renault;
• NVV (Hydraulic Brake Booster) - Volkswagen, Audi, Skoda.

Ke habohlokoa ho bolela hore litsamaiso tse joalo li kenngoa likoloing tseo ho nang le "anti-lock braking system" (ABS), 'me tabeng ea likoloi tsa Fora, AFU e etsa mesebetsi e' meli:

• vacuum brake pedal booster - analogue ea BAS;
• kabo ea braking force ka mabili ke analogue ea EBD.

A re boneng sehloohong sena sa Vodi.su hore na mothusi oa brake o sebetsa joang le hore na mokhanni o fumana melemo efe ka ho e sebelisa.

Molao-motheo oa ts'ebetso le morero

Emergency Brake Assist (BAS) ke sistimi e tsoetseng pele ea elektroniki e thusang mokhanni ho emisa koloi nakong ea braking e thata. Liphuputso le liteko tse ngata li bontšitse hore maemong a tšohanyetso, mokhanni o hatella brake pedal ka tšohanyetso, ha a sa sebelise matla a lekaneng ho emisa koloi kapele kamoo ho ka khonehang. Ka lebaka leo, sebaka sa ho emisa se telele haholo 'me likhohlano li ke ke tsa qojoa.

Setsi sa elektroniki sa Brake Assist, se thehiloeng ho data ho tsoa ho sensor ea brake pedal le li-sensor tse ling, se lemoha maemo a joalo a tšohanyetso mme se "tobetsa" pedal, ho eketsa khatello ea brake fluid tsamaisong.

Ka mohlala, likoloing tsa Mercedes, mothusi o bulela feela haeba lebelo la brake pedal rod le feta 9 cm / s, ha ABS e buletsoe, mabili le mabili a tsamaisoang ha a thijoe ka ho feletseng, kahoo mokhanni o fumana monyetla oa ho qoba. skidding, mme sebaka sa ho emisa se fetoha se khuts'oane - re se re buile ka Vodi.su ka bolelele ba sebaka sa braking le hore na se angoa joang ke boteng ba anti-lock.

Ke hore, mosebetsi o tobileng oa Brake Assist ke ho sebelisana le brake booster le ho eketsa khatello tsamaisong ea maemo a tšohanyetso. Sesebelisoa se sebetsang sa mothusi oa brake ke makenete ea motlakase bakeng sa koloi ea molamu - ho sebelisoa tšusumetso ho eona, ka lebaka leo pedal e hatelloang fatše.

Haeba re bua ka molekane oa Fora - AFU, joale molao-motheo o tšoanang o sebelisoa mona - maemo a tšohanyetso a tsejoa ka lebelo la ho hatella brake. Tabeng ena, AFU ke sistimi ea vacuum mme e sebelisana le "vacuum brake booster". Ho phaella moo, haeba koloi e qala ho skid, AFU e etsa mosebetsi oa ho arola ka matla a elektronike (EBD), ka ho koala kapa ho notlolla mabili a motho ka mong.

Ho hlakile hore moetsi leha e le ofe o leka ho atolosa haholo bokhoni ba likoloi tsa bona, kahoo mefuta e mengata e mecha e na le mefuta e fapaneng ea sehlooho sa mothusi oa brake. Ka mohlala, ho Mercedes e tšoanang, ba ile ba qala ho kenya tsamaiso ea SBC (Sensotronic Brake Control), e etsang mesebetsi e mengata hang-hang:

• kabo ea matla a braking lebiling le leng le le leng;
• e sekaseka boemo ba sephethephethe;
• e lekanya linako tsa ts'ohanyetso, eseng feela lebelo la ho hatella brake pedal, empa hape le lebelo la ho fetisetsa leoto la mokhanni ho tloha pedal ea khase ho ea ho brake;
• ho eketseha ha khatello tsamaisong ea mariki.
