Recently, Cabin air filter is widely used in automotive vehicle to fulfill customer's 'well-being' demands. But survey reports show many customers feel difficulties in recognizing appropriate replacement schedule of cabin air filter which causes the performance downshift of air conditioning system. Accordingly, we studied a cabin air filter changing alarm system. HVAC conditions. driving area, and the material of cabin air filter are considered throughout this alarm system, and the analyzed results call inform the customers for the replacement schedule when dust amount of cabin air filter reaches to a set point. Test results of this system shows the detection accuracy is satisfied within 8 percents error range.

Step by step, Safety Regulations become strict rules in all countries of the world. Especially, In the ECE R-14, European Regulation, All seats will have to be equipped with 3 point seat belt from 2004. 10. So in this paper, We will investigate the safety regulation about 3 point seat belt and propose the high strength frame to rear center belt-in seat satisfying regulations, ECE R-14 and FMVSS 210. and then we will accomplish the FEA and Test with proposed seat frame. So we should confirm the application of proposed seat frame.

As OCS(occupant classification system) becomes an essential parts for the advanced airbag system in the north American market, various systems are introduced to the market. WCS(Weight Classification System) which place between leg mounting bracket and slide rail is one of the solution to match the regulation. In this paper, a series of design/analysis/optimization/test is performed in order to improve structural integrity and safety performance. A standard DFSS technique is adopted and the results shows the optimized configuration shows good behavior on both strength and safety without much weight increase.
