e Electrics/Electronics Architecture of the New MAN Truck Generation The new MAN Truck Generation sets standards in terms of digitalizing the trucks of tomorrow. The futureproof, central electrics/electronics architecture is characterized by modularity, scalability, expandability and openness. It thus represents the platform for current and future technologies, such as the electrified powertrain or automated driving.

REQUIREMENTS FOR THE TRUCK OF TOMORROW
The developments in electronics over the last 20 years show an exponential increase in complexity, which has a massive impact on the underlying meth ods, processes, development tools, and people, but also on the E/E architecture and the systems themselves. The de mands on the truck of the future are constantly increasing. The product development cycle in the commercial vehicle sector has some special features and differs significantly from the cycles in passenger car develop ment. The long model cycles are particu larly characteristic. For example, a new model generation is launched every 15 to 20 years and a facelift of the model reaches the market about every six to
eight years. New functions and sys tems are developed further every year and integrated into the vehicle series over model years. A high degree of variance, driven by numerous everyday applications, continues to characterize the commercial vehicle sector. In addi tion to this, a commercial vehicle rep resents a capital good. The Total Cost of Ownership (TCO), reliability and future viability of the truck play an important role. In order to meet the requirements of a new, future-oriented truck genera tion in development, a new methodical architectural approach is needed. It is necessary to create a customer-oriented approach, which in particular guaran tees the temporal stability of the new E/E architecture in order to meet the requirements of long life cycles.

A NEW METHODOLOGY ENABLES THE ARCHITECTURAL APPROACH
The currently predominant image of an E/E architecture is a component- oriented representation that shows the mapping of control units and bus con nections. The disadvantages of this approach are particularly apparent in the implementation of new, innovative functions in which hardware and soft ware components interact with each other across ECUs and lead to higherlevel functionality. As early as 2003, MAN laid the foun dation for today’s E/E architecture and, with the help of a new meta-model, radi cally changed the previous approach to an architecture topology. The basic approach of requirements analysis, con cept development/programming and ATZ worldwide 09|2020
evaluation is not changed in the process. Rather, the goal is to create a time-stable, customer-oriented approach to how the results of hardware and softwa
