to be aware of the transmission error. The corrupted frame by Abstract-The Controller Area Network (CAN) is widely used errors will be retransmitted automatically when the bus is idle for distributed systems in automotive and other applications such again. as safety-critical applications. As such, it is necessary to evaluateThe error detection and recovery features provide CAN a the property of the continuous working ability of a CAN node. In this paper we setup a discrete time Malkov chain model based on mhigh tolerance to network faults. However, as the recovery the fault confinement mechanisms of CAN to calculate how long a mechanism involves retransmitting any corrupted messages, a CAN node can work normally before it goes into its "bus-off' faulty node could flood the network with erroneous error state. An example will be given to show the theoretical conclusion frames or unnecessary retransmissions. To prevent such events finally. happening, the CAN protocol uses fault confinement mechanisms to detect permanent hardware disfunctioning and Index Terms-Controller Area Network (CAN), reliability, wthoffut oe.Tedtie ehnssi ecie electromagnetic interference, fault confinement, real-time in on fes systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
