Summary:

A novel scheduling concept, called switched scheduling, for efficient bandwidth usage in a FlexRay cluster is introduced. It assumes a synchronized FlexRay cluster divided into several branches using an intelligent active star. The concept allows the simultaneous usage of the same timeslot by different nodes as well as the realization of slot multiplexing without changing the FlexRay protocol version 2.1. Furthermore it enables the usage of heterogeneous cycle configurations for each branch while synchronization is still provided for the whole cluster. In addition to the scheduling concept a design approach based on AUTOSAR is presented to enable the model-driven development of the resulting schedule which is called multidimensional schedule
