Abstract:
Real-time theory is introduced to analyze reliability and robustness for ECU (Electronically Controlled Unit) of vehicle AMT (Automatic Mechanical Transmission). Real time analysis architecture is proposed. Analysis and simulation for the four working stages of AMT are illustrated. The results show, the real time system model with 9 tasks working on 4 processors is reasonable, and the designed Blended Timer-Triggered Scheduler is feasible as well as robust, which provide the system more extendibility and reliability.
