Authors Abstract
Content
Safety critical systems are taking demands on automotive systems where the distributed embedded system needs a communication system with properties of fault tolerant real-time communication. In order to increase reliability of systems with serial communication, a device called bus guardian can be added on physical layer to perform management of schedules and data independently from the communication controller, monitoring timing and sending signals of bus status notifying error occurrences to the host. The goal of this paper is to present and perform a comparative analysis of different strategies of bus guardian used in CAN, TTP/C and Flexray protocols, applied in safety critical system in automobile domain. A comparison was carried out to describe the properties and application for each protocol.
