7、ion) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be r

8、epresented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards

9、 are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Internat

10、ional Standard requires approval by at least 75 % of the member bodies casting a vote. In exceptional circumstances, when a technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art“, for example), it may decide b

11、y a simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely informative in nature and does not have to be reviewed until the data it provides are considered to be no longer valid or useful. Attention is drawn to the possibility that some of the

12、 elements of this Technical Report may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/TR 15497 was prepared by the United Kingdom Motor Industry Software Reliability Association (MISRA) as guidelines published in 1994, and was ad

25、d by the Department of Trade and Industry and the Engineering and Physical Sciences Research Council, I am pleased to support the publication of these guidelines. In this programme we have been concerned to ensure that the results of research should not be buried in learned papers, but promulgated i

26、n ways which will affect practice in industry. We have therefore sought the involvement of user organizations so that the work based on an understanding of their real industrial needs, and so that the results will be credible to their peers. The MISRA Study, with its combination of vehicle and equip

27、ment manufacturers, has admirably realized that ambition. The voluntary nature of the guidelines is important. They were produced voluntarily, for the benefit of both the industry and the public. Their adoption will also be voluntary. This has encouraged the MISRA consortium to develop guidelines wh

28、ich offer genuine benefits for their users, rather than burdensome restrictions. The renowned cost-consciousness of the automotive industry might be thought by some to diminish its contribution to technological development. On the contrary: while this industry is properly cautious in the interests o

29、f safety, the fiercely competitive market and the public exposure of any problems ensures that the commercial value of new technology is thoroughly evaluated. This sector is a hard proving-ground for technology. So, while many of the issues on which the MISRA consortium has concentrated are specific

30、 to vehicles, other sectors might do well to see what they might glean from the trends here. Bob Malcolm DTI-EPSRC Safety Critical systemsISO/TR 15497:2000(E) ISO 2000 All rights reserved ix Foreword (continued) iii The motorist gains many benefits, including enhanced safety features, from advances

31、in vehicle electronics. The development of software is a specialized and often complex area where much relies on an effective approach by those directly involved. I welcome MISRAs initiative and efforts in developing these safety related guidelines and advice under a joint DTI, EPSRC and industry fu

32、nded programme. The guidelines reflect a responsible and serious industry attitude to safety issues. Malcolm Fendick BSc CEng FIMechE Chief Mechanical Engineer Department of Transport The use of electronic systems in vehicles has increased significantly over recent years and will continue to increas

33、e. Much time and resources are being committed by vehicle manufacturers to deal with the compatibility of such systems in particular the problem of interference from external sources. The vehicle owner expects his vehicle to be reliable and safe, and this includes the electronic systems. Electronic

34、systems are dependent on the software provided by the manufacturer. The greater complexity of such systems is increasing the need to maintain software quality and reliability. This has resulted in the need for a unified approach to software design. It is therefore pleasing that an independent group

35、has produced these guidelines on vehicle-based software which will be of benefit to the Motor Industry and also more importantly the motorist.
