Nekuwedzera kuri kuda kwemota dzevatyairi uye mota dzekutengesa, midziyo yemagetsi yemotokari inoshandiswa zvakanyanya mumotokari. Kuti ive nechokwadi chekuita kwakajairika kweaya maturusi emagetsi mune yakagadzikana magetsi emagetsi system, zvakakosha kukunda dambudziko rekukanganiswa kukuru kwemagetsi kunokonzerwa nemotokari panguva yekushanda, iyo inopararira kune magetsi emagetsi system kuburikidza nekubatanidza, conduction, uye radiation, kuvhiringidza kushanda kwe-on-board equipment. Naizvozvo, iyo yepasi rose mwero ISO 7637 yakaisa pamberi kusadzivirirwa zvinodiwa zvemotokari zvigadzirwa zvemagetsi pane magetsi.
ISO 7637 yakajairwa, inozivikanwawo se: Mota dzemumugwagwa-Kukanganisika kweMagetsi kunogadzirwa nekuita uye kubatanidza, ndeye electromagnetic kuenderana chiyero chemotokari 12V uye 24V magetsi emagetsi masisitimu. Iyo inosanganisira ese ari maviri emagetsi kutsungirira uye emission zvikamu zve electromagnetic kuenderana bvunzo. Ese aya mazinga anotsanangura zvinodikanwa zveparameter zvezviridzwa nemidziyo inogona kushandiswa kuburitsa tsaona dzemagetsi uye kuita bvunzo. Kubva nhasi, ISO 7637 standard yakaburitswa muzvikamu zvina. Kubva nhasi, ISO 7637 yakajairwa yakaburitswa muzvikamu zvina kuratidza nzira dzekuyedza uye maparamendi ane hukama zvizere. Ipapo isu tichanyanya kusuma chikamu chechipiri chechiyero ichi, ISO 7637-II, icho chinoshandiswa kuyedza kuenderana kwepiritsi redu rakashata.
ISO 7637-II inodaidza magetsi ekufamba-famba pamwe chete nemitsetse yekugovera chete. Inodoma bvunzo dzebhenji dzekuyedza kuenderana nekuita magetsi emidziyo yakaiswa pamotokari dzevatyairi uye dzakareruka dzekutengesa mota dzakaiswa 12 V yemagetsi system kana mota dzekutengesa dzakaiswa 24 V yemagetsi system-yese majekiseni uye kuyerwa kwezvipfupi. Failure mode severity classification yekusadzivirirwa kune zvenguva pfupi inopihwa zvakare. Inoshanda kune aya marudzi emotokari yemumugwagwa, yakazvimirira yepropulsion system (semuenzaniso spark ignition kana injini yedhiziri, kana mota yemagetsi).
ISO 7637-II bvunzo inosanganisira akati wandei akasiyana enguva pfupi voltage waveform. Mipendero inokwira nekudonha yeaya pulses kana waveforms inokurumidza, kazhinji mu nanosecond kana microsecond renji. Izvi zviyedzo zvemagetsi zvenguva pfupi zvakagadzirirwa kutevedzera tsaona dzese dzemagetsi dzinogona kusangana nemotokari pasi pemamiriro epasirese, kusanganisira kuremerwa. Kuve nechokwadi chekushanda kwakagadzikana kwe-on-board zvishandiso uye kuchengetedzeka kwevafambi.
Kubatanidza ISO 7637-II inoenderana rugged piritsi mumotokari kunopa akawanda mabhenefiti. Kunyanya, kusimba kwavo kunovimbisa kushanda kwenguva refu uye kushanda kwakavimbika, kuderedza mari yekugadzirisa uye kuwedzera kubereka kwese. Chechipiri, iyo ISO 7637-II inoenderana nerugged piritsi inopa chaiyo-nguva kuoneka uye kutonga kweruzivo rwakakosha, optimize mota diagnostics uye kuwedzera kugona. Chekupedzisira, mahwendefa aya anogona kubatana zvisina mutsetse nemamwe masisitimu emotokari nemidziyo yekunze, achiwedzera kutaurirana uye kudyidzana. Nekutevedzera chiyero ichi, tinogona kuvaka kuvimbika, kuisa kuvimba, uye kuendesa zvigadzirwa zvepamusoro zvinosangana nezvinodiwa nevatengi.
Inoteedzerwa neISO 7637-II yakajairwa yekudzivirira magetsi ekudzivirira, iwo mahwendefa ane rugged kubva ku3Rtablet anokwanisa kumira kusvika ku174V 300ms mota yekukwira kwemoto uye inotsigira DC8-36V yakakura voltage magetsi. Iyo inovandudza kusimba kwekushanda kwakakosha mu-motokari masisitimu akadai telematics, navigation interfaces uye infotainment kuratidza pasi pemamiriro ezvinhu akaomarara uye kudzivirira kurasikirwa kunokonzerwa nekusashanda zvakanaka.
