Abstract—The CAN protocol is widely used in the distributed embedded systems. It has been shown that a shared-clock scheduling algorithm can be used along with CAN to implement time triggered architecture. However, the shared-clock scheduling algorithms are mostly used along with the time triggered co-operative schedulers, despite these algorithms provide reliable solutions for many applications, they suffer some key limitations. This paper proposes a shared-clock hybrid scheduling algorithm which employs the time triggered hybrid scheduler. And then the performance of the novel algorithm is analyzed. Finally, a simulation model is built by using TrueTime toolbox in MATLAB platform. The results indicate that the scheduler can improve clock synchronization accuracy, reduce the jitter, and strengthen the real-time character of the system.
