Abstract
The time-triggered architecture for CAN is analyzed. The implementation issue of time- triggered architecture based on 8052 single-chip processor and CAN controller SJA1000 is designed. The maximum number of transmission messages in basic cycle is given. And the scheduling capability is analyzed. The experiment is based on the automotive engine management, the result proves that using time-triggered architecture can not only manage the message transmission but also improve the bandwidth utilization.
