Current market trend indicates an increased interest in replacing mirrors by camera monitoring systems (CMS) to reduce CO2 emissions while at the same time improve driver visibility in future cars with a more aerodynamic profile. This improvement in visibility is expected to be more beneficial during the night or under extreme weather conditions. A CMS is an advanced system composed of an electronic imager, a display, and an intelligent electronic control unit. The CMS is intended to provide at least the same level of functionality of mandatory and legally prescribed interior and exterior mirrors in vehicles as specified in various international regulations and standards such as FMVSS 111 and SAE J985. Such system must take into consideration not only the required external field of view (FoV), but also the physical constraints of the human operator, i.e. visual acuity. This captured information is subsequently displayed to the driver inside the cockpit.

Magneto-rheological (MR) fluid is a novel composite material and can be used in different components of vehicle. Magneto-rheological fluids (MRF) are suspensions of micron sized whose yield stress varies rapidly as the change of magnetic field applied. The use of magneto-rheological (MR) fluids in vehicles has been gaining popular recently due to its strong rheological effect, fast response, good stability and low energy consumption, which give automotive designers more dimensions of freedom in functional designs. Nowadays, most of the related research of MRF is about the construction of the prototype and the realization of the brake force. However, due to a lack of optimal design and the understanding of MRF and magnetic field, the main research progress is only about the simulation which makes the braking effect of the prototype can hardly meet the requirement of vehicle.

Today new automotive engine design is optimized in term of mass. However, in term of stiffness, optimizations mainly consider eigenfrequency criteria. But in assembly components with quite low stiffness cumulated microslip phenomena can occur when the structures are subject to cyclic loadings. After a while, macro-displacements will be observed and then failures of the assembly will take place. Bush, plain bearing, roller bearing in conrod or in gearbox can be subject to this kind of problem. In this paper, after a short description of various mechanisms which can cause microreptation phenomena, two types of cumulated microslip occurring in engine and gearbox are presented. Behavior specifities will be highlighted to remind how particular are cumulated microslip. From the field, it appears that both phenomena arise with a low probability of occurrence. It implies not to use the devices concerned by this problem to investigate the phenomenon.

The condenser opening area plays a vital role in the A/C Performance of the vehicle particularly during the idling. This paper presents the detail study on the effects of the condenser opening area on the A/C performance. Based on the theory, the effect of the condenser opening area is studied and it is validated by the experimental results. Based on these results an optimum value of the condenser opening area required for the best A/C performance is concluded.
