Kev txhim kho ntawm kev tsim qauv ntawm kev ntsuas speedometer raws li tus neeg tsav tsheb stepper tsav tsheb
Piv nrog rau analog hluav taws xob, stepper motor meters muaj uniform indexing, zoo repeatability ntawm pointers, ceev teb, jitter me me, stability thiab kev ntseeg tau ntawm cov khoom zoo [1], yog li stepping lub cev muaj zog-hom tsheb seev maj maj plaws hauv China. Xws li cov cuab yeej automotive feem ntau siv lub microcontroller los tsav lub cav xaib mus rau tus tsav lub cim ntsuas. Lub microcontroller tswj cov kauj ruam kev tsav tsheb feem ntau xav tau ib qho kev tsav tsheb sab nraud feem ntau, thiab cov cuab yeej tshwj xeeb ntawm kev tsav tsheb ua kauj ruam tsav tsheb ua ke yuav ua kom yooj yim rau kev siv software thiab kho vajtse kom zoo thiab ua kom muaj kev ruaj ntseg thiab kev ntseeg ntawm qhov ntsuas. Tsab ntawv no qhia thiab sib piv cov qauv kev ua haujlwm ntawm cov kws tsav tsheb nyob hauv Suav teb. Thaum kawg, tus speedometer yog tsim los nrog MC33991 ua los ntawm Freescale Semiconductor ua piv txwv.
