Nowadays, lightweight automotive component design, regarding fuel consumption, environmental pollutants and manufacturing costs, is one of the main issues in the automotive societies. In addition, considering safety reasons, the durability of the automotive components, as one of the most important design requirements should be guaranteed. In this paper, a two-step optimization process including...

the liquid metal flow and the solidification behaviours in a multi-cavity casting mould of two automotive cast parts were simulated in three dimensions. the commercial code, flow-3d® was used because it can track the front of the molten metal by a volume of fluid (vof) method and allows complicated parts to be modeled by the fractional area/volume obstacle representation (favor) method. the gre...

Security research and training using cyber-physical systems (e.g., automotive networks) is challenging because of the need to replicate the interactions between the hardware components and the control software of the systems. These interactions are challenging to replicate due to dynamic inputs in real-world environments that cause various interactions of hardware components and control softwar...

To transmit the revolutions of crankshafts to camshafts and auxiliary mechanisms, ordinary automotive engines are equipped with engine components such as timing belts, timing chains and accessory drive belts. Recently, as automotive engine performance is being greatly enhanced, the requirements for their components have become increasingly demanding. In this context, autotensioners play an impo...

Without further advances in standardization it no longer be possible to master the growing complexity of automotive electronics. In the 1990s automotive OEMs such as DaimlerChrysler went to great efforts to establish the OSEK[1] embedded operating system as a binding standard for in-house developments and supplier components. Today the real-time and multitasking capable operating system is used...

Modern vehicles consist of many interconnected, software-based IT components which are tested very carefully for correct functional behavior to avoid safety problems, e.g. that the brakes suddenly stop working. However, in contrast to safety testing systematic testing against potential security gaps is not yet a common procedure within the automotive domain. This however could eventually enable...
