A method to handle CRC errors on the basis of FlexRay

Abstract

It is very important to communicate between the many electronic components in automobiles. If any component has an error, is possible for the error to affect other components. We propose a method of handling cyclic redundancy check (eRe) errors in the network using FlexRay. The FlexRay vehicle network protocol features fault-tolerance and guaranteed message latency. According to the FlexRay specification, each node in the FlexRay network decodes received messages and checks for various errors. However, if error occurs to any node, other nodes on the network do not know that a particular node generated an error. In this case, the node that did not receive the critical message cannot be guaranteed to demonstrate correct behavior. In order to solve this problem, we suggest a solution using dynamic messages supported by the FlexRay protocol. ©2009 IEEE.
