The benefits of computer-based or 'programmable electronics' systems are well accepted; such as standardised hardware, greater complexity and ease of modification. The merits of the computer-based systems, however, do not mean an improvement in safety or system integrity. The increasing capability and complexity of these systems can lead to errors introduced during development remaining undetected in the delivered system. In addition, random component failures may also contribute to undesirable vehicle control. In the control of risk, an analysis or random hardware failures should be considered to determine whether any potentially dangerous failures can occur and whether such failures are likely to be managed by the system. Furthermore, systematic (or design) failures should also to be subjected to various measures and techniques to determine any weaknesses in the design process that could result in errors in the system. The paper presents the viewpoint from emerging standards on the achievement of risk control.
