Development of Safety and Dependability Aspects for Fault Tolerant Automotive Embedded System

The objective of the paper is to propose a development of safety and dependability aspects (DSDA) model for a fault tolerant automotive embedded system with enhanced fault detection and recovery capability for future controlled behavior. The fault or error detection latency is to be minimal and then only any recovery action can be triggered at the earliest time to minimize the system failure. The synthesis of such a programmable system using fault tolerant dual controller area network (FT-CAN) is considered to predict the probable time of failure. The most probable input values that cause the failed state variable in a dependable system are identified in distributed embedded components. The focus is not only to identify the faulty states and developed safe transitions but also identify and predict the best recoverable states and minimize the recovery time. A working model with CAN and a micro controller is designed for the reliability prediction when the system satisfies the safety and stability criteria. This is essential with respect to several dependability attributes, such as safety reliability and Trust
