- Abstract:
- This work deals with an educational system for the teaching of standard FlexRay (FR). The FR is a new communication standard intended to be used in cars in the near future. It is primarily intended for communication among so-called x-by-wire systems. Many fundamental and advanced features of FR standard, as well as basic kinds of x-by-wire systems, can be demonstrated by this educational system. The largest benefit is in an illustrative presentation of the FR synchronization mechanism (SM) in operation, as well as of its robustness. The SM is probably the most important FR process, and provides synchronization among time bases in a FR network. The educational system allows the disturbance of the time bases by modification of clock frequency. External generators are used for this purpose. The changes in SM behaviour can be observed as a result of time base disturbing. The most interesting observation is to what degree the SM is able to cope with this clock frequency fluctuation. No similar FR educational systems have previously been equipped with a possibility like this.
