Abstract (EN): Transmission errors in a flexible distributed communication system based on the Flexible Time-Triggered Controller Area Network protocol (FTT CAN) must be confined and controlled if such a system is to be used in a safety critical real-time environment. This paper presents a first approach to error confinement in FTT CAN using a deterministic error model. Two strategies to cope with such errors are presented. In the first one the error model is introduced in the schedulability analysis causing the allocation of extra time in each elementary cycle. The second one is based on bus traffic monitoring and on a dynamic scheduler with a schedulability analyzer. The impact of this last strategy on the FTT CAN master node architecture is discussed and a possible solution is presented. Copyright (C) 2001 IFAC.
