In recent years the number of electronic systems fitted to road vehicles worldwide has increased, with further growth forecast. Many such systems are appearing in safety-critical or safety-related applications.
An objective assessment of the integrity of the systems is necessary to ensure that the safety of the driver, occupants and other road users will not be compromised. Certain disciplines associated with reliability, namely environmental validation, failure mode and effects analysis and software verification and validation are examined. The need for a coordinated approach to system integrity is discussed, and the development of European standards and guidelines described.
