Reliability Analysis of CAN nodes under Electromagnetic Interference

Abstract

The Controller Area Network (CAN) is widely used for distributed systems in automotive and other applications such as safety-critical applications. As such, it is necessary to evaluate the property of the continuous working ability of a CAN node. In this paper we setup a discrete time Malkov chain model based on the fault confinement mechanisms of CAN to calculate how long a CAN node can work normally before it goes into its "bus-off" state. An example will be given to show the theoretical conclusion finally.
