Nekuda kwekuwedzera kuri kuita kudiwa kwemotokari dzinotakura vanhu nemotokari dzekutengeserana, zvishandiso zvemagetsi zvemotokari zvinoshandiswa zvakanyanya mumotokari. Kuti zvive nechokwadi chekuti zvishandiso izvi zvemagetsi zvinoshanda zvakanaka mumagetsi akagadzikana, zvakakosha kukunda dambudziko rekukanganiswa kukuru kwemagetsi kunokonzerwa nemotokari panguva yekushanda, uko kunopararira kumagetsi kuburikidza nekubatanidza, kufambisa, uye mwaranzi, zvichikanganisa mashandiro emidziyo iri muchikepe. Nokudaro, standard yepasi rose ISO 7637 yakaisa zvinodiwa zvekudzivirira hutachiona hwezvigadzirwa zvemagetsi zvemotokari pamagetsi.
ISO 7637 standard, inozivikanwawo se: Road vehicles–Electrical interference inokonzereswa ne conduction and coupling, ndiyo electromagnetic compatibility standard yemotokari 12V ne 24V power supply systems. Inosanganisira zvikamu zve electromagnetic endurance uye emission pakuongorora electromagnetic compatibility. Mitemo iyi yese inotsanangura zvinodiwa zve parameter yemidziyo nemidziyo inogona kushandiswa kuburitsa tsaona dzemagetsi nekuita bvunzo. Nhasi uno, ISO 7637 standard yaburitswa muzvikamu zvina. Nhasi uno, ISO 7637 standard yaburitswa muzvikamu zvina kuratidza nzira dzekuyedza uye ma parameter ane chekuita nazvo zvizere. Zvadaro tichanyanya kuunza chikamu chechipiri cheiyi standard, ISO 7637-II, iyo inoshandiswa kuyedza compatibility ye tablet yedu yakasimba.
ISO 7637-II inodaidza magetsi enguva pfupi ari mumitsetse yekugovera chete. Inotsanangura bvunzo dzebhenji dzekuyedza kuenderana nemagetsi enguva pfupi ari mumichina yakaiswa pamotokari dzevatakuri nemotokari dzebhizinesi dzakareruka dzine sisitimu yemagetsi ye12 V kana mota dzebhizinesi dzine sisitimu yemagetsi ye24 V - yekupinza uye yekuyera ma transients. Kupatsanurwa kwehuremu hwenzira yekukundikana kwekudzivirira ma transients kwakapihwawo. Inoshanda kune idzi mhando dzemotokari dzemumugwagwa, dzisingabatanidzwi nesystem yekufambisa (semuenzaniso spark ignition kana injini yedhiziri, kana mota yemagetsi).
Bvunzo yeISO 7637-II inosanganisira mafungu akasiyana-siyana emagetsi anochinjika. Mipendero inokwira nekudzika yemafungu aya kana mafungu inokurumidza, kazhinji iri mu nanosecond kana microsecond range. Kuedza uku kwemagetsi anochinjika kwakagadzirirwa kutevedzera tsaona dzese dzemagetsi dzingangosangana nemotokari mumamiriro ezvinhu chaiwo, kusanganisira load dump. Kuve nechokwadi chekuti michina iri mundege inoshanda zvakanaka uye kuti vafambi vakachengeteka.
Kubatanidza piritsi rakasimba rinotevedzera ISO 7637-II mumotokari kune mabhenefiti akawanda. Chikuru ndechekuti, kugara kwenguva refu kwavo kunovimbisa kushanda kwenguva refu uye kushanda kwakavimbika, kuderedza mari yekugadzirisa uye kuwedzera kugadzirwa kwezvinhu. Chechipiri, piritsi rakasimba rinotevedzera ISO 7637-II rinopa kuoneka uye kudzora ruzivo rwakakosha panguva chaiyo, richivandudza kuongororwa kwemotokari uye rinowedzera kushanda zvakanaka. Chekupedzisira, piritsi iri rinogona kubatana zvakanaka nedzimwe nzira dzemotokari nemidziyo yekunze, zvichiwedzera kutaurirana uye kushanda pamwe chete. Nekutevedzera mwero uyu, tinogona kuvaka kuvimbika, kusimbisa kuvimbana, uye kupa zvigadzirwa zvepamusoro zvinosangana nezvinodiwa nevatengi.
Zvichienderana neISO 7637-II standard transient voltage protection, mapiritsi aya akasimba anobva ku3Rtablet anokwanisa kutsungirira kusvika ku174V 300ms vehicle surge impact uye anotsigira DC8-36V wide voltage power supply. Izvi zvinoita kuti zvive nyore kushandisa masisitimu akakosha mumota akadai setelematics, navigation interfaces uye infotainment displays mumamiriro ezvinhu akaoma uye kudzivirira kurasikirwa kunokonzerwa nekusashanda zvakanaka.
