This invention provides a conflict-aware transactional reconstruction method and apparatus for vehicular networks, belonging to the field of vehicular network configuration and scheduling control technology. It solves problems such as multi-node time slot conflicts, cross-device submission asynchrony, and inability to quickly roll back after update failures in existing vehicular network transactional reconstruction processes. The method includes: upon receiving a reconstruction request, generating a set of scheduling update operations based on the reconstruction request and the latest scheduling status table of each device node in the vehicular network; establishing a conflict graph and a dependency graph based on the scheduling update operation set; determining a set of transaction execution layers and the corresponding hierarchical execution sets for each transaction execution layer based on the conflict graph and dependency graph; and performing transactional reconstruction on each device node based on the set of transaction execution layers and the corresponding hierarchical execution sets, including differential patch pre-writing, atomic pointer switching triggered by a unified timestamp, and distributed consistency monitoring.
