Abstract: CAN bus real-time scheduling algorithm is proposed to satisfy the need for real-time and bandwidth dynamic allocation of CAN bus in electric vehicle. Backend channel configure database is used for modification of CAN bus channels at runtime. Requirements of modification in research and execute phases are meet properly by this algorithm. The algorithm shortens the time of the research and development time.

Key words: CAN bus, real-time scheduling, electric vehicle
