That’s exactly how we develop digital solutions. Not just technology for its own sake, but always with an eye to the benefits for users and developers. Driver assistance systems need to operate with foresight and work safely at all times. We explain the requirements that thereby emerge for development and how they can be effectively taken into account in the development process. Whether and to what extent digitalization is new, or in fact familiar, in the auto- motive industry is analyzed by two Porsche experts in our interview. Finally, you can read about how our in-house-developed testing proce dure for connectivity applications streamlines the development process—and highlights the possi- bilities of digitalization for developers and users alike. DIGITALIZATION Porsche Engineering MAGAZINE 9 Forward-Looking and Safe New requirements for the fields of function development, testing grounds and validation In recent years, advanced driver assistance systems (ADAS) have evolved from mere display and warning functions into applications with ever higher degrees of automation. Increasing automation yields new, substantially more demanding requirements in the fields of function development, test grounds and validation.

Porsche Engineering Magazine 1/2021 EDITORIAL 3 Dear Reader, “Next level”—scarcely any other expression sums the situation in which we currently find ourselves more succinctly: In many fields, we simply have to reach the next level. We are familiar with the term from the worlds of computer games and sports. Those who have reached a certain level there often move on to the next level right away. This also applies to our work in automotive development: We cannot rest on our laurels. We see this in trends such as artificial intelligence, the use of game engines in vehicle development and future E/E architectures, which we examine in the title series. They exemplify the increasing complexity of our work. We also have to reach the next level in our methods. In his article, Marius Mihailovici, Managing Director of our digital branch in Cluj, explains what this looks like in the software development sector.

The cylinder bores are formed using exposed hard silicon crystals, rendering the use of cylinder liners redundant. The lower crankcase (bedplate) is also constructed using die-cast aluminum. Due to the extreme forces, grey cast iron inlays are used to reinforce the bedplate construction. These also limit crankshaft bearing clearances over a greater temperature range and thus have a positive effect on the oil flow rate.

This acronym comes from the German words; VAriable NOckenwellen Steuerung, which means Variable Camshaft Control. The M62 TU VANOS system is a new variant providing stepless VANOS functionality on each intake camshaft. The system is continuously variable within its range of adjustment providing optimized camshaft positioning for all engine operating conditions.
