ITire Pressure Monitoring System (TPMS) ilumkisa umqhubi weenguqu eziphawulekayo zoxinzelelo kuyo nayiphi na amathayi amane kwaye ivumela umqhubi ukuba abonise uxinzelelo lomntu ngamnye kwiZiko loLwazi loMqhubi (i-DIC) ngelixa isithuthi sihamba kunye nendawo.
I-TPMS isebenzisa imodyuli yokulawula umzimba (BCM), i-instrument panel cluster (IPC), i-DIC, i-radio frequency (RF) i-sensors yoxinzelelo lokuhambisa kunye neesekethe zedatha ye-serial kwi-wheel / tire assembly ukwenza imisebenzi yenkqubo.
I-sensor ingena kwimodi yokumisa xa isithuthi simile kwaye i-accelerometer ngaphakathi kwe-sensor ayisebenzi.Kule modi, isampuli zenzwa zoxinzelelo lwesondo rhoqo ngemizuzwana ye-30 kwaye ithumela kuphela ukuhanjiswa kwemodi yokuphumla xa uxinzelelo lomoya lutshintsha.
Njengoko isantya semoto sinyuka, amandla e-centrifugal avuselela i-accelerometer yangaphakathi, ebeka i-sensor kwimodi yokuqengqeleka.Kule modi, iisampulu zenzwa zoxinzelelo lwesondo rhoqo ngemizuzwana ye-30 kwaye ithumela ukuhanjiswa kwemowudi yonke imizuzwana ye-60.
I-BCM ithatha idatha equlethwe kwi-transmission ye-RF ye-sensor nganye kwaye iyiguqulele kwi-sensor ye-sensor, i-sensor mode, kunye noxinzelelo lwesondo.I-BCM ke ithumela uxinzelelo lwesondo kunye nedatha yendawo yetayili kwi-DIC ngokusebenzisa i-serial data circuit, apho iboniswa khona.
I-sensor ihlala ithelekisa isampuli yoxinzelelo lwangoku kwisampuli yangaphambili yoxinzelelo kwaye idlulisele kwimodi yokulinganisa nanini na xa kukho utshintsho lwe-1.2 psi kuxinzelelo lwesondo.
Xa i-TPMS ibona ukwehla okukhulu okanye ukunyuka koxinzelelo lwesondo, umyalezo othi "CHECK TYRE PRESSURE" uya kubonakala kwi-DIC kwaye isalathisi esisezantsi siya kubonakala kwi-IPC. Bobabini umyalezo we-DIC kunye nesalathisi se-IPC sinokucinywa ngokulungelelanisa. Uxinzelelo lwetayara ukuya kuxinzelelo olucetyiswayo kunye nokuqhuba isithuthi ngaphezu kweekhilomitha ezingama-25 ngeyure (40 km/h) ubuncinane imizuzu emibini.
I-BCM nayo iyakwazi ukubona iimpazamo ngaphakathi kwe-TPMS.Nayiphi na impazamo efunyenweyo iya kubangela ukuba i-DIC ibonise umyalezo othi "SERVICE TYRE MONITOR" kwaye igcine ibhalbhu ye-TPMS IPC ilayitiwe umzuzu omnye ngexesha ngalinye ukulayishwa kuvuliwe de impazamo ilungiswe. .
Xa i-TPMS ibona ukuhla okuphawulekayo koxinzelelo lwesondo, umyalezo othi "CHECK TYRE PRESSURE" uya kubonakala kwi-DIC kwaye isalathisi soxinzelelo oluphantsi luya kubonakala kwipaneli yesixhobo.
Imiyalezo kunye nezalathisi zinokucocwa ngokulungelelanisa amathayi kuxinzelelo olucetyiswayo kunye nokuqhuba isithuthi ngaphezu kwe-25 mph (40 km / h) ubuncinane imizuzu emibini. Ukuba enye okanye ngaphezulu kweenzwa zoxinzelelo lwesondo okanye ezinye iinqununu zenkqubo ziye zahluleka, okanye ukuba zonke abenzi boluvo abacwangciswanga ngempumelelo.Ukuba isibane sesilumkiso sisakhanya, kukho ingxaki ngeTPMS.Nceda ubhekiselele kulwazi lwenkonzo yomenzi ofanelekileyo.
