The research on minimizing the engine vibration by using Pneumatic Active Engine Mount (PAEM) was performed in the paper. The dynamics of the PAEM represented by analytical Matlab/Simulink model was analyzed. The PAEM model were verified compared with experimental results by using MTS. In addition, the parameter sensitivity analysis was also conduced to identify the dominant parameter for the PAEM performance.

When vehicle crashes into pedestrian, it perceives the crash. And automatically it goes up its hood which prevents pedestrian header from second collision of vehicle"s hood or wind shield part. And through impact buffer effect, it reduces bodily harm rate of pedestrian"s header. This system needs many kinds of components. First, It needs sensor for crashing perceive and ECU is for judging what is the crash object. If the object is a pedestrian, hood is gone up. At that time, this system also needs Actuator. Nowadays, AHLS is applied for many real vehicles. And this system is comprised of many kinds of sensor, ECU, Actuator. In this research, Actuator is one of AHLS major components. So, this research has been studied about workings of Actuator. But there are many kinds of Actuator workings. Especially, this research analyzed Spring, Solenoid, Latch Mechanism of Actuator.

In order to maximize the safety and convenience of the occupants in the automobile field in recent research and development of intelligent systems are actively conducted. In addition, the importance of pedestrian safety is increasing more and more. In recent years, the issue of pedestrian safety is emerging worldwide for decreasing the pedestrian injury and the established safety standards have been made in order to reduce the damage of the pedestrian. In Korea, automotive industries are committed to technology development of the active hood system to satisfy safety standards, but the development effort of parts manufacturers is insufficient. Therefore, it is expected that the core technology of the active hood system by developing a pedestrian discrimination algorithm.
