In the future the number of environment and safety-relevant intelligent systems will be rising to an even higher number. Advances in technology will result in a considerably higher degree of cross linking in vehicle systems in future. The present report of WP320 gives an overview on the actual status, future tendencies and the requirements of these developments. Due to an increasing number of vehicle systems in a coexistent architecture, a premium class vehicle can achieve a total number of up to 75 ECUs. The recent increase of complexity, especially for electronically controlled mechatronic systems is not only defeated in a clearly increased weight of vehicles but also in a degradation of the reliability of these new technologies what can recently seized e.g. through actual brake down statistics. In order to be able to be active towards the future developments it is necessary to anticipate them as they require new methods and mechanisms for their on- and off-board diagnostics for vehicle maintenance and technical inspection. Therefore, WP320 consist of a research of actual and future technologies and functions of vehicle safety and of exhaust relevant systems. In order to be able to set up different roadmaps for the derivation and anticipation of future tendencies, the systems have been categorised in a first and evaluated by vehicle experts in so-called function and technology matrixes in a second step. These matrixes including the corresponding functions ad technologies are available as MS-Excel tables. The most relevant and central aspects have been analysed in several roadmaps, further tendencies can easily be derived by the function and technology matrixes. This function and technology tables including the expert evaluation are joint to this report. The assessment of the reliability of the roadmapped future functions and technologies has not been assessed within the framework of WP320. Here the impact of multiple implicators like also the strong development of software development processes, set up like e.g. through AUTOSAR and legal regulations basing on IEC61508 are not assessable in an absolutely reliable way A central roadmap (Fig. 1-1) shows actual and future chassis technologies and their impact on driverassistant functions. The future of the development of automotive technology clearly shows a concentration on functions the customer needs and accepts. This trend is also driven in order to stabilize the reliability of electronic systems. Like the depicted roadmap shows, the assessment of functions and technologies witch has been carried out in this WP gives the possibility to categorise and to illustrate various interrelations between functions and technologies in all vehicle domains for today and for the future developments.
