Method for operating communication node of flex ray communication system of e.g. car, involves determining whether reestablishment of communication between controller and process computer is allowed when error occurs in computer

摘要

The method involves providing a communication node, and interrupting communication between a communication controller i.e. flex raycontroller, and a processor computer of the node when an error occurs in the computer. A determination is made to find whether security instructions enable synchronous disconnection of communication to a communication system i.e. flex raycommunication system, when the error occurs. A determination is made to find whether reestablishment of the communication between the controller and computer is allowed when the error occurs. An independent claim is also included for a communication node comprising a processor computer.
