These days automotive markets are launching models that include a variety of IT technologies. Tesla's Tesla model S and Google's unmanned automobiles are emerging one after another. This type of automobile with IT technology provides various convenience to the driver and the driver is getting benefit by various conveience services. on the contrary, it is also true that defects for errors in electronic components cause accidents that threaten the safety of drivers. There is a sudden unintended acceleration among these accidents. The cause of the accident is not clear yet, but the claim that the ECU device caused by the magnetic field causes accident of the car due is the most reliable. But, in Korea, when occur a car sudden unintended acceleration accident, the char maker often claims that an accident occurred due to driver's pedal malfunction. Also most drivers are responsible for the lack of grounds to refute. In this paper, the pedal operation image of the driver is acquired and the sensor is attached to the control part such as the excel and brake so as to discriminate whether the vehicle sudden unintended acceleration accident is the driver's pedal operation error or the fault of. i have implemented a system that can do this.

In the present study, we proposed a simulation model of vacuum booster with AMESIM software to predict the output characteristic. And we performed the sensitivity analysis of output characteristic with main design parameters, such as diaphragm diameter. All of these parameters are main design parameters in the procedure of vacuum booster design. The simulation results of this paper offer qualitative information of vacuum booster output. Therefore, the simulation results of this paper will be used effectively for the design procedure of vacuum booster in the industrial field.

A two-dimensional static biomechanical model of lower extremity in the seated posture was developed to assess muscular activities of lower extremity required for a variety of foot pedal operations. Muscle forces of the model were predicted using the double linear optimization scheme. For the model validation, three subjects performed the experiments which measured EMG activities of six lower extremity muscles. Predicted muscle forces were compared with the corresponding rectified intergrated EMG amplitudes and it showed reasonable results.

국내에서 사용되는 트랙터는 출력과 상관없이 쟁기 작업을 포함한 농작업, 운반작업 등이 주로 사용되는 편이나, 북미 또는 서유럽의 경우 소형 트랙터는 토목공사의 로더, 굴삭 작업 또는 잔디깍기 등의 농장 및 정원 관리용 등으로 주로 사용되며 쟁기 작업은 거의 하지 않는다. 이와 같은 목적으로 사용하는 트랙터는 견인력을 적게 요구하는 대신 잦은 변속 및 전후진의 방향 전환을 요구하므로, 기계식 트랙터로써는 많은 불편함을 느낄 수밖에 없다. HST 트랙터는 다양한 작업성을 만족시키는 동시에 조작성이 편리하다는 장점이 있다. (중략)
