The purpose of this study is to suggest a concept of automotive seat design to reduce the structural weight and to develop the seat frame strength. In the paper, structural analysis required for development of seat frame was accomplished according to the test requirements by FMVSS 202. Using optimum design, upper and lower bracket detected as stress concentrated points were reinforced to reduce the maximum stress value. The most effective way to reduce the weight of seat frame is to use lighter materials like aluminum. The weight of aluminum seat frame could be reduced to about 43% compared with the existing steel seat frame.

The latest vehicle yields a superior safety and reduction of driving burden by monitoring the driving state of vehicle and its environment with various sensors. To detect other vehicles and objects of the rear left and right-side blind spot area of driver. provide the information about a existence of objects inside the blind spot, and give a signal to avoid collision, this study proposes the intelligent outside rear-view mirror system. This task has substantially complicated several factors. For example, the size, geometry and features of the various vehicles which might enter the monitored zone is varied widely and therefore present various reflective characteristics. This study proposes the optical system and optimal configuration of IR array sensor, controller design to detect and judge a presence of other vehicles and shows the results of the performance evaluation of developed system.

To detect other vehicles and objects of the rear left and right-side blind spot of driver, provide the information about a existence of objects inside the blind spot, and give a signal to avoid collision, this study proposes the intelligent outside rear-view mirror(IOSRVM) system. This task has substantially complicated several factors.
