In view of the problems that the limited identifier bits of CAN frames make it difficult to implement information deadline encoding when applying earliest deadline first (EDF) scheduling in the controller area network (CAN) bus, and strict time synchronization is required for all nodes to update deadlines simultaneously, an EDF scheduling algorithm based on bus arbitration is proposed, and the principle of the EDF scheduling algorithm and the schedulability analysis method are introduced. Finally, the scheduling algorithm is applied to the scheduling of electric vehicle control system information, and the feasibility of the scheduling algorithm is verified.
