【Abstract】To adapt to the centralized computing electronic and electrical architecture under the trend of "software-defined vehicles"，this paper conducts adaptive developmentandoptimization design forthe digital keysystem. First，sortout theevolutionlogicofautomotiveelectronicand electricalarchitecturefrom distributed，domaincontrol to vehicle-cloudintegratedcentralized （EEA3.O）;Furthermore，thepainpointsexisting inthetraditionaldigitalkeysystem underthedistributedarchitecture，suchas functional independence，insuficientlogstorage，and weakdata collboration ability，are analyzed，and an adaptation solution based on the EEA 3.O architecture is proposed.
