In the different domains, as shown in Chapter 1, there are different types of electronic control units (ECUs). Many automotive ECUs differ from non-automotive equipment in the requirements (environment, reliability) and realisation details. Besides general advice on EMC design, these particular problems of automotive ECUs are highlighted in this chapter.
