1. Linear log ceev sensor
Linear log ceev sensor yog tsim los ntawm cov hlau nplaum ruaj khov, ncej ncej, induction kauj thiab iav nplhaib. Thaum lub iav nplhaib tig, lub hau ntawm lub iav thiab lub nraub qaum rov qab hloov qhov sib txawv ntawm cov polar axis. Thaum lub sij hawm kev sib hloov ntawm lub nplhaib iav, cov hlau nplaum sib nqus nyob rau hauv lub induction coil hloov pauv los tsim kom muaj lub zog hluav taws xob, thiab cov teeb liab no tau pub rau ECU ntawm ABS los ntawm lub cable ntawm qhov kawg ntawm induction kauj. Thaum qhov ceev ntawm lub nplhaib iav hloov, qhov zaus ntawm qhov induced electromotive quab yuam kuj hloov.
2, lub nplhaib log ceev sensor
Lub nplhaib log ceev sensor yog tsim los ntawm cov hlau nplaum ruaj khov, induction kauj 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 sib nqus nyob rau hauv lub induction coil hloov pauv los tsim induced electromotive quab yuam, thiab cov teeb liab yog nkag mus rau hauv hluav taws xob tswj chav tsev ntawm ABS los ntawm cable nyob rau hauv qhov kawg ntawm induction kauj. Thaum qhov ceev ntawm lub nplhaib iav hloov, qhov zaus ntawm qhov induced electromotive quab yuam kuj hloov.
3, Hall hom log ceev sensor
Thaum lub iav nyob rau ntawm txoj hauj lwm qhia nyob rau hauv (a), cov kab hlau nplaum uas dhau los ntawm Hall lub caij yog dispersed thiab lub magnetic teb kuj tsis muaj zog; Thaum lub iav nyob rau hauv txoj hauj lwm qhia nyob rau hauv (b), cov kab hlau nplaum uas hla dhau lub Hall lub ntsiab yog concentrated thiab lub magnetic teb kuj muaj zog. Raws li cov iav rotates, qhov ntom ntawm cov kab hlau nplaum uas dhau los ntawm Hall lub caij hloov, yog li ua rau muaj kev hloov pauv hauv Hall voltage. Lub ntsiab Hall yuav tso tawm ib millivolt (mV) theem ntawm quasi-sine yoj voltage. Lub teeb liab kuj yuav tsum tau hloov los ntawm ib qho hluav taws xob hluav taws xob mus rau hauv tus qauv mem tes voltage.
