【Abstract】This paper systematicaly expounds the architecture scheme and design principle of the welcome light efect of thebody control module（BCM），analyzes the interaction logic of BCMand instrument module（ICM）in the lighteffectcontrol，and introduces thecomposition of common welcome light efect.In termsof architecture design， BCM，as thecoreunitof theefectcontrolof the welcomelight，accuratelycontrols the lightingonandoff and the combination modeaccording to various inputsignals.Atthe levelof interaction logic，BCMand ICMwork togetherto efectivelypreventtheabnormalpromptoftheinstrumentduring theexecutionofthelampeffect.Datainteractionwith infotainment system AVNTtorealize thepersonalizedsettng oflightefect；Combined withthedoor module DCM，the externalrearviewmirrorturnsignalisincorporatedintothelightefectsystem；ThroughthegatewayGWM，thespeed signalof the brakecontrol system BCSand the gear signalof thegearcontrolmodule GCMarereceived toensure that the welcomelightefectisactivatedonlywhenthevehicleisinPgearand thespeed iszero.Inaddition，various typesof headightssuch as low lightand high beam lightcreateadiversifiedwelcome light efectthrough diferentcombinationsof light and off.
