    In recent years, ITS projects in Japan, Europe and the US have been characterized by a strong emphasis on safe driver assistance systems designed to prevent traffic accidents. As it has become clear that eradicating accidents will be impossible by means of vehicle passive safety and single-vehicle active safety efforts alone, research and development of systems for preventing accidents through road-to-vehicle cooperation and vehicle-to-vehicle cooperation have been promoted in Japan (ASV, AHS), Europe (PReVENT, SAFESPOT) and the US (VII). The key to such technologies is road-to-vehicle communications and inter-vehicle communications. On the other hand, a number of driver assistance systems have been brought to market, including lidar-based forward collision warnings, ACC, lane keeping support and drowsiness warnings, but their penetration rates in Japan are extremely low. Furthermore, one major challenge is that safe driver assistance systems based on road-to-vehicle and vehicle-to-vehicle cooperation are premised upon a high penetration rate. Finally, we introduce a system for improving driver acceptance of safe driver assistance systems based on driver monitoring and forward monitoring as well as cooperative driver assistance systems for elderly drivers, an issue now receiving attention in Japan.

    Nowadays, wide variety of rubber hoses is adopted in car with different construction, inner diameter and length, etc. As manifold fluids flow inside those hoses, wide variety of rubber material is utilized. Due to recent trend towards environmental protection, drastic change is expected in hose performance, especially of fuel and air conditioning hose. As for air conditioning hose, how to hold both flexibility and gas barrier performance is utmost concern. In this paper will be reported a recently tackled new approach for providing flexible high gas-barrier rubber materials by applying adsorption phenomena of currently used refrigerant, R-134a, to tetramethylammonium-treated mica. Also trend of future refrigerants will be discussed finally.

    Rubber is used in the fuel systems of cars, and so, it is important to predict the automotive fuel in the future. In this report, the history of automotive fuels is outlined, and the future of them is considered. Bio-fuels are expected for carbon-neutral fuels, but their use is in face of the food problem. It is very important to develop technologies to produce ethanol from cellulosic biomass.

    Wiper blade rubber is a very important part in the automotive wiper system. Wiper blade is used under the severe environment, then many characteristics are required besides wiping ratio, low-abrasion, low-friction, low-deformation and so on. To satisfy the function, besides the rubber material, surface treatment and coating are also important technologies.

    Tire technology has grown with the development of the automobile technology. A hundred years of the history have given lots of benefits to human life, but also put negative influence on the global environment. Tire manufacturers have been developing the innovative technology to meet the three major requirements, such as “safety”, “environment” and“comfort”. This review describes the history of tire materials developments, which have been stimulating the development of tire technology, and refers to the recent trends in tire technology.
