System Safety in Computer-Controlled Automotive Systems
نویسنده
چکیده
Computers are quickly taking over safety-critical functions in transportation systems. Not surprisingly, we are starting to experience incidents and accidents related to the software components in these systems, including a recent recall related to ABS failure. Software allows unprecedented complexity and coupling in these systems, and these factors are stretching our current engineering techniques for assuring acceptable risk. This paper summarizes the state of the art in software system safety and suggests some approaches possible for the automotive and other industries.

متن کاملAutomated Freedom from Interference Analysis for Automotive Software
Freedom from Interference for automotive software systems developed according to the ISO 26262 standard means that a fault in a less safety critical software component will not lead to a fault in a more safety critical component. It is an important concern in the realm of functional safety for automotive systems. We present an automated method for the analysis of concurrency-related interferenc...
