Automotive sensors yog lub luag haujlwm rau kev sau thiab xa cov ntaub ntawv.
1. Lub tsheb sensor yog cov khoom siv nkag ntawm lub tsheb computer system. Nws hloov cov ntaub ntawv ntawm ntau yam kev ua haujlwm thaum lub sijhawm ua haujlwm ntawm lub tsheb mus rau hauv cov teeb liab hluav taws xob thiab xa mus rau lub khoos phis tawj kom lub cav ua haujlwm zoo tshaj plaws. Thaum lub tsheb sensor tab tom nrhiav kev ua txhaum, ntxiv rau kev kuaj xyuas lub sensor, tab sis kuj tseem kuaj xyuas cov hlua hluav taws xob, cov khoom sib txuas, thiab cov khoom sib txuas ntawm lub sensor thiab lub tshuab hluav taws xob tswj.
2. Lub sensor tuaj yeem muab faib ua ob pawg raws li kev sib raug zoo ntawm lub zog, hom nquag, thiab hom passive. Feem ntau ntawm cov sensors siv nyob rau hauv tsheb yog passive, thiab lub sensor xav tau ib tug sab nraud fais fab mov los tsim ib tug hluav taws xob teeb liab. Lub teeb liab tso zis los ntawm lub sensor feem ntau suav nrog cov cim analog thiab cov teeb liab digital. Cov teeb liab digital tuaj yeem nkag ncaj qha mus rau chav tswj hluav taws xob, thaum lub teeb liab analog yuav tsum tau hloov mus rau hauv cov teeb liab digital los ntawm A / D converter thiab tom qab ntawd nkag mus rau hauv chav tswj hluav taws xob.
3. Nyob rau hauv lub tsheb instrumentation system, lub luag hauj lwm ntawm lub sensors ntawm ntau yam twj paj nruag yog hloov lub cev tsis xws li engine kub, roj siab, ceev, kis tau tus mob tso zis ncej ceev, thiab roj tank roj theem mus rau hauv cov voltages, thiab tam sim no, los yog hluav taws xob. mem tes. Lub tsheb tswj hluav taws xob muaj xws li cov sensors, hluav taws xob tswj ECU, thiab actuators.
