Abstract
Systems and methods described herein provide for assigning classifications to signals and corresponding messages for prioritization and transmission across a vehicle CAN bus. The assigned classifications are used to prioritize messages, signals, and nodes of the vehicle CAN bus. The classifications are used to prioritize critical messages and high priority messages that control operations of the vehicle system.
