Purpose – This paper presents a VHDL-AMS based genetic optimisation methodology for fuzzy logic controllers (FLCs) used in complex automotive systems and modelled in mixed physical domains. A case study applying this novel method to an active suspension system has been investigated to obtain a new type of fuzzy logic membership function with irregular shapes optimised for best performance. Desi...

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...

α/β titanium alloys are choice materials for aeronautical and automotive industries due to their high performance to density ratio. For several applications, fatigue resistance is one of the critical design parameter. Particularly, initiation of fatigue crack plays a key role. Furthermore, hardly anything can be found in the literature on the fatigue crack initiation in multiphase microstructur...

Leaf springs are used as suspension elements in the front and rear axles of vehicles automotive industry, especially heavy commercial vehicles. working all road conditions under load, it provides damping loads transmitted from wheel ground to chassis. In this way, ensures safety comfort vehicle. Mechanical systems have been replaced by air new generation systems; Z type parabolic leaf springs, ...

Tire normal forces are difficult to measure, but information on the vehicle force can be used in many automotive engineering applications, e.g., rollover detection and wheel stability. Previous papers use algebraic equations estimate tire force. In this article, estimation of is formulated as an input problem. Two observers proposed solve problem by using a quarter-car suspension model. First, ...
