Review and Prospect of Integration Compatibility in Digital Vehicles: Multi-Dimensional Challenges and Industry Practice

Integration compatibility has emerged as a prominent challenge in the development of digital vehicles. This paper provides a comprehensive review of previous research on automotive integration compatibility, categorizing the relevant challenges into three main categories: technical, organizational, and methodological. Furthermore, the paper distinguishes between challenges encountered during the initial integration phase and those encountered during continuous integration according to the nodes of the start of production. By engaging in discussions with internal experts from an original equipment manufacturer (OEM) and other related enterprises regarding these challenges, the paper identifies the most pressing issues that require novel solutions, which are the current practical pain points of OEMs, thereby providing directions for future research.
