چکیده انگلیسی
CAN with flexible data rate (CAN FD) is considered the next generation in-vehicle network standard for automotive cyber-physical systems. CAN FD supports a data phase bit-rate of up to 10â¯Mbps and message payload of up to 64 bytes. However, the substantial differences regarding the allowed message payloads and the heterogeneity of the signal periods indicate the need for a systematic design method to fully utilize its large transmission bandwidth. We propose an optimized design method for CAN FD to minimize bandwidth utilization while meeting the signal timing constraint. First, two slack evaluation metrics are defined for the quantitative analysis of the potential packing choices. Based on these metrics, we propose a clustering-based signal packing algorithm, and the schedulability of the signals and the packed messages are both verified. The proposed method is compared with other design methods proposed for both CAN and CAN FD. The experimental results demonstrated that our method is the most bandwidth efficient and can meet the timing constraint simultaneously.
