Bit transmission error correction scheme for FlexRay based automotive communication systems

In the FlexRay communication network systems which are configured as a large number of ECUs (Electronic Control Units) and network topologies, the receivers have the different asymmetric transmission delays which cause the transmission errors. As the complexity of the communication network topology in vehicle increases, the asymmetric delay is getting longer. In this paper, the error estimation and correction scheme to ensure the integrity of the signal during operation when the transmission error occurs due to the asymmetric delay is proposed. Simulation results show the proposed scheme can correct the transmission errors effectively in performance.
