Ibrake pedal anti-lock braking system (antilockbrakesystem) yemoto ngokudibeneyo ibizwa ngokuba yi-ABS. Umsebenzi kukulawula ukunyanzeliswa kwenkqubo ye-braking system ye-braking system xa i-braking i-braking, ukwenzela ukuba amavili angavalwanga ngamavili kwaye abe kwimeko yokuguqa kunye nokutyibilika (izinga lokuhamba li malunga ne-20%), ukwenzela ukuba kuqinisekiswe ukunamathela kwamavili kunye nomhlaba. Amandla eqhina akwixabiso eliphezulu.
Umsebenzi woluvo lwesantya sevili kwi-ABS kukulinganisa ngokuchanekileyo umlinganiselo wokuhanjiswa kwevili kwimoto. Isivamvo sesantya sevili sibhaqa isiginali yefrikhwensi (uphawu lobungakanani bokudluliselwa) kokujikeleza kwevili ngalinye, kwaye emva koko ithumela lo mqondiso kwikhompyuter ye-ABS yombane. Xa isantya siqinisekisiwe kwixabiso elilinganisiweyo, i-pad ye-brake ye-emergency brake i-brakes inkqubo kwaye inkqubo ye-ABS iqala ukusebenza. Xa ikhompyuter ye-ABS ilawula ivili ukuze ikhulule umzuzwana, isantya soluvo lwesondo sithumela umqondiso wekhefu obona ukujikeleza kwetayara ukusuka kwi-braking ukuya kwikhompyuter ye-elektroniki ye-ABS, ukuze i-ABS ilawule i-brake pad ukuphumeza owona mgama ungcono wokuqhawuka. Uluhlu olubanzi lwezivamvo zesantya samavili ikakhulu lubandakanya izivamvo zesantya zesondo zemagnetoelectric kunye neHolo yohlobo lwesantya sevili.
Isivamvo sesantya sesondo semagnetoelectric siyilwe ngokufaka iskimu sempembelelo yemagnethi yombane wangoku. Ilula kwisakhiwo, indleko ephantsi, ingoyiki amabala odaka, kwaye ayifuni izixhobo zokuhambisa amandla, kwaye isetyenziswa ngokubanzi kwiinkqubo zokunqanda ukutshixa i-ABS. Kodwa kukho nezinye izinto ezingalunganga, ezifana ne-phase-frequency characterism ayiphezulu, xa isantya siphezulu kakhulu, i-phase-frequency factor of the sensor ayikwazi ukugcina, nto leyo enokukhokelela lula kwiimpawu zobuxoki. Kukwakho ukungakwazi ukumelana nokuphazamiseka kwe-electromagnetic. Imo yamaza ilinganiswe ngokuchanekileyo yi-analog oscilloscope ikwimilo ye-sine function wave, kwaye okukhona uphezulu umlinganiselo wothumelo lwevili, kokukhona umqondiso wemveliso usebenza umgangatho wobungakanani bomgangatho wombane.
I-Hall-type-wheel speed sensor yenziwa ngokusebenzisa ingcamango esisiseko yesiphumo seHolo. Isignali yayo yokuphuma ayonakaliswa lula ngesantya sombane oqhelekileyo kunye nexabiso lamandla. Ineempawu eziphezulu zenqanaba lokuphindaphinda kunye nekhono elinamandla lokuchasana ne-anti-electromagnetic wave, kodwa kufuneka libe nezixhobo zokuhambisa amandla. Bafana, ngoko ke inzwa yenza imilinganiselo echanekileyo yomzekelo:
Ekuqaleni, qhagamshela i-BNC kwintambo yentloko yebhanana kwindawo yokukhusela ye-analog oscilloscope. Intloko ebomvu ixhunywe kwinaliti njengenqanaba elihle, kwaye umgca wesignali we-sensor uxhunyiwe. Intloko emnyama ye-acne inokudibaniswa nekliphu ye-alligator okanye inaliti njengenkqubo engafanelekanga yokumisa.
Vula i-toolbar yokuphuma yokhuseleko ye-oscilloscope ye-analog, setha umlinganiselo wokulahleka kokhuseleko lokuphuma kwi-1X, ulungelelanise igiya yemoto ethe nkqo kwi-1V / div, kwaye ufake isiseko sexesha malunga ne-10ms, emva koko ungayilungisa ngokweenkcukacha.
Kuba isivamvo sesantya sesondo sohlobo lweHolo sinesixhobo sokuhambisa umbane wesekethe, kufuneka kubekho umbane olawulwa yi-DC omalunga ne-11-12V ukujonga i-waveform ngeli xesha.
Phakamisa isithuthi ngejekhi, jija ivili, kwaye ulinganise ngokuchanekileyo i-wave wave ye-sensor yesiginali nge-oscilloscope yemoto ye-analog.
Abenzi boluvo besiphumo seholo babandakanya umazibuthe osisigxina okanye isiphaluka esivaliweyo kunye nentsimi ye-electromagnetic ephantse yacinywa ngokupheleleyo, i-magnetic tile fan impeller ijika isithuba phakathi kwemagnethi kunye nentsimi ye-electromagnetic, kwaye ayinabungozi xa ibhokisi yencam kwi-impeller ye-fan ivumela intsimi yamagnetic. i-fan impeller ivumela isiseko semagnethi kunye nemagnethi yomoya iyonke xa ibhokisi yokukhawuleza ivuliwe kwaye ivaliwe, okukhokelela kwisiphumo seHolo. Isivamvo sesiphumo siqhagamshelene kwaye sicinywe njengokutshintsha kwamandla, yiyo loo nto ezinye iinkampani zeemoto zibhekisa kwi-sensor yesiphumo seholo kunye nezinye izixhobo zombane ezifanayo njengesixhobo sokutshintsha amandla eholo, esi sixhobo somatshini sinombane ophezulu weSwitchgear. Ke ngoko, umqondiso we-waveform ye-Hall effect sensor yi-pulse enye emva kwenye, oko kukuthi, i-waveform.
Ukukhawuleza umlinganiselo wokuhanjiswa kwevili kukuba, ukukhawuleza ukuphindaphinda kwe-waveform yesignali iba, kodwa i-AC yangoku yonxibelelwano lwayo ihlala ifana, yonke ukusuka kwi-0V ukuya kwi-1V. Ukucothisa isantya sokujikeleza kwevili, unokubona ukuba ukuphindaphindeka kwefom yesignali kuyancipha.
Ukuba i-digital display ye-ABS sensor ine-voltage ye-0 kuphela yokusebenza kwe-voltage esemgangathweni yemveliso, kufuneka ihlolwe kuqala ukufumanisa ukuba inokutshintshwa kobonelelo lwesekethe yombane. Emva koko kugqitywe ukuba i-frequency ye-signal ye-sensor ilandela ngokusondeleyo umlinganiselo wevili, ngaphandle koko kubonisa ingxaki eqhelekileyo.
