Vibration of real vehicle originates an engine drive and form of road surface. It begins a fatigue accumulation of vehicle driver, with technology for restraint to vibration of vehicle is going to research and application. The vehicle seat vibrator is a simulator for vibration of real vehicle reappears. Vehicle vibration generated of virtual experiment a driver feel in vibration area. The oil pressure type vehicle seat vibrator of preexistence is limiting a vibration test plan of small scale for make because of high cost; with vehicle seat vibrator using single electric actuator develops. It study analyses systems limit and dynamics of vehicle seat vibrator. And control algorithms apply electric actuator for vibration test.

This paper proposes the lane recognition using the hough transform and the lane prominence. First, the lane recognition is started on a coordinate transformation. camera coordinate system is changed to world coordinate system by inverse perspective transform. Second, the lane extraction substitutes a embossing effect for the edge detection of the sobel and the canny. third. the hough transform is used to recover from the unreliable lane. Not only multiple lanes but also a lane is detected by the proposed algorithm that showed the lane recognition rate higher then canny edge detection.
