Hauv lub neej feem ntau cov neeg tuaj yeem tsav tau, thiab ntau tus neeg paub txog Anti-lock Braking System (ABS), tab sis pes tsawg tus neeg paub txog ABS sensors?
ABS sensor yog siv nyob rau hauv ABS ntawm lub cev muaj zog tsheb.Hauv ABS system, inductive sensors yog siv los saib xyuas lub tsheb ceev.Lub ABS sensor tso tawm ib txheej ntawm quasi-sinusoidal alternating tam sim no cov cim los ntawm kev ua ntawm lub nplhaib iav uas tig nrog lub log.Qhov zaus thiab amplitude muaj feem xyuam rau lub log ceev.Lub teeb liab tso zis tau xa mus rau ABS hluav taws xob tswj chav tsev (ECU) kom paub txog lub sijhawm saib xyuas lub log ceev.
Hom tsiaj loj
Linear log ceev sensor
Lub linear log ceev sensor yog tsim los ntawm cov hlau nplaum ruaj khov, ncej ncej, induction coils thiab lub nplhaib iav.Thaum lub nplhaib iav tig, cov hniav txhuam hniav thiab qhov sib txawv ntawm cov hniav sib hloov tawm tsam cov polar axis.Thaum lub sij hawm kev sib hloov ntawm lub nplhaib iav, cov hlau nplaum flux hauv induction coil hloov ua ib qho induced electromotive quab yuam.Cov teeb liab no yog nkag mus rau ABS hluav taws xob tswj chav tsev los ntawm lub cable ntawm qhov kawg ntawm induction kauj.Thaum qhov ceev ntawm lub nplhaib iav hloov, qhov zaus ntawm induced electromotive quab yuam kuj hloov.
Lub nplhaib log ceev sensor
Lub nplhaib log ceev sensor yog tsim los ntawm cov hlau nplaum ruaj khov, induction coils thiab lub nplhaib iav.Cov hlau nplaum ruaj khov yog tsim los ntawm ob peb khub ntawm cov hlau nplaum.Thaum lub sij hawm kev sib hloov ntawm lub nplhaib iav, cov hlau nplaum flux hauv induction coil alternately generated induced electromotive quab yuam.Cov teeb liab no yog nkag mus rau ABS hluav taws xob tswj chav tsev los ntawm lub cable ntawm qhov kawg ntawm induction kauj.Thaum qhov ceev ntawm lub nplhaib iav hloov, qhov zaus ntawm induced electromotive quab yuam kuj hloov.
Hall hom log ceev sensor
Thaum lub iav tig, qhov sib nqus flux ceev dhau los ntawm Hall lub caij hloov, uas ua rau Hall voltage hloov.Lub ntsiab Hall yuav tso tawm ib millivolt (mV) theem quasi-sine yoj voltage.Cov teeb liab no kuj yuav tsum tau hloov mus rau hauv tus qauv pulse voltage los ntawm hluav taws xob circuit.
ABS sensor yog ib feem tseem ceeb ntawm ABS system.ABS tuaj yeem muab kev ua si tag nrho rau qhov cuam tshuam ntawm nres thaum tsav tsheb, txo qhov kev ncua deb, tiv thaiv kev sib tsoo lossis log tsheb xauv thaum muaj xwm txheej ceev, ua kom lub tsheb ruaj khov thiab ua kom lub zog tswj tau ntawm lub tsheb, Nws tuaj yeem zam qhov kev sib txhuam hnyav ntawm lub log tsheb thiab hauv av, txo cov log tsheb noj thiab ua kom lub neej ua haujlwm ntev ntawm lub log tsheb.
